Multi-State Sales Tax Nexus Exposure for Growing Businesses

How a growing business accidentally accumulates sales tax obligations in states it has never set foot in, what triggers that obligation, and how Mike Habib, EA — a Whittier, California tax representation firm — helps businesses find and fix multi-state exposure before it becomes a crisis.

A business does not have to open an office in another state, hire an employee there, or even ship a single truck across state lines to end up owing that state sales tax. Under the rules that have governed interstate commerce since 2018, simply selling enough into a state — through your own website, through Amazon, through a wholesale customer, through anything — can be enough to create a legal obligation to register, collect, and remit sales tax there, whether or not you ever realized the obligation existed. This is called economic nexus, and it is the single most common way a genuinely successful, growing business ends up with a multi-state tax problem it never saw coming.

The exposure tends to surface at exactly the worst possible moment: during due diligence for a sale of the business, during a bank’s underwriting process for a loan or line of credit, or years later when a state’s automated data-matching program flags a mismatch between marketplace-reported sales and registered tax accounts. By that point, the business may owe back taxes across a dozen states, with penalties and interest compounding the entire time no one realized there was a problem to solve.

This guide explains exactly what “nexus” means, how the rules changed in 2018, what specific dollar and transaction thresholds different states use, why marketplace sales complicate the calculation rather than simplifying it, what a Voluntary Disclosure Agreement actually does, and how Mike Habib, EA — a Whittier, California based tax representation practice — helps growing businesses find their real exposure and resolve it on the most favorable terms available. Every legal citation, dollar threshold, and program detail in this guide has been verified against primary state and federal sources before being written down.

Part One: What “Nexus” Actually Means, and Why the Rules Changed Completely in 2018

What Does “Sales Tax Nexus” Mean in Plain Terms?

Nexus is simply the legal term for the connection between a business and a state that is sufficient to give that state the constitutional authority to require the business to collect and remit its sales tax. For most of the history of American sales tax law, that connection required physical presence — an office, a warehouse, an employee, inventory stored in the state, or some other tangible footprint. If your business had no physical presence in a state, that state could not require you to collect its sales tax, no matter how much you sold to customers located there.

What Changed, and Why Does Every Discussion of This Topic Mention a Case Called “Wayfair”?

On June 21, 2018, the United States Supreme Court decided South Dakota v. Wayfair, Inc., and the decision fundamentally rewrote the rules that had governed this area for decades. The Court overturned two earlier precedents — National Bellas Hess v. Department of Revenue (1967) and Quill Corp. v. North Dakota (1992) — that had required physical presence before a state could impose a sales tax collection obligation. In their place, the Court upheld a South Dakota law that asserted economic nexus: the idea that a sufficiently large volume of sales into a state, on its own, creates enough of a connection to justify the tax obligation, even with zero physical footprint in that state.

The specific South Dakota law at issue in the case required out-of-state sellers to collect and remit sales tax once they delivered more than $100,000 of goods or services into the state, or engaged in 200 or more separate transactions with South Dakota customers, in the current or prior calendar year. The Supreme Court found this threshold reasonable — large enough to protect genuinely small, incidental sellers from an unreasonable compliance burden, while still capturing the kind of substantial, ongoing commercial activity that justified requiring the seller to collect tax. Critically, the Court did not create a single national standard; it simply held that an economic nexus law structured this way was constitutionally permissible, opening the door for every other state to enact its own version.

Did Every State Adopt Exactly the Same $100,000/200-Transaction Threshold?

No, and this is precisely where the compliance burden for a growing business becomes genuinely difficult. In the years following Wayfair, every state that imposes a sales tax enacted its own economic nexus law, but no two are identical. Dollar thresholds across the states range from roughly $100,000 up to $500,000, and some states pair the dollar threshold with a transaction-count requirement (typically 200 transactions) while others rely on the dollar figure alone. Some states require both a dollar and transaction threshold to be met before nexus is triggered; others require either one to be met. Some measure the threshold using gross sales including exempt and resale transactions; others count only taxable retail sales. A handful of states have no transaction-count threshold at all, using a pure dollar test regardless of how many individual transactions it took to get there.

This lack of uniformity is not a minor technical footnote — it is the entire reason multi-state nexus tracking is genuinely difficult for a growing business to manage without dedicated attention. A business selling into all fifty states is not applying one rule fifty times; it is tracking fifty different, independently defined tests, each with its own measurement period, its own definition of what counts toward the threshold, and its own effective date.

Part Two: California’s Own Rules, and Why Marketplace Sales Complicate Everything

What Is California’s Specific Economic Nexus Threshold?

California set its threshold through Assembly Bill 147, codified at California Revenue and Taxation Code section 6203(c)(4), effective April 1, 2019. The rule requires a remote retailer to register with the California Department of Tax and Fee Administration (CDTFA) and collect California use tax once its combined sales of tangible personal property delivered into California exceed $500,000 in the preceding or current calendar year. This threshold has not changed since it took effect, and it remains one of the highest dollar thresholds of any state — five times the $100,000 figure most other states adopted.

Two details about California’s rule matter enormously in practice. First, California uses a pure dollar test with no transaction-count threshold at all — a business that ships ten thousand small orders totaling $499,999 into California has not triggered nexus, while a business that ships three enormous orders totaling $500,001 has. Second, and this catches an enormous number of growing businesses by surprise: marketplace-facilitated sales still count toward your $500,000 threshold, even though the marketplace itself (not you) is the one actually collecting and remitting the tax on those specific transactions.

If Amazon Is Already Collecting California Tax on My Marketplace Sales, Why Would I Ever Need to Register Myself?

Because your obligation is measured by your total California sales across every channel combined — your own website, wholesale accounts, and every marketplace you sell through — not by whether any particular channel already has its own tax collection arrangement. A seller with $300,000 in Amazon sales (where Amazon collects and remits as the marketplace facilitator) and $210,000 in direct sales through their own website has $510,000 in total California sales. That crosses the $500,000 threshold. The Amazon sales themselves remain Amazon’s collection responsibility as the marketplace facilitator, but the direct website sales — which no marketplace is collecting tax on — now require the seller to register with CDTFA and begin collecting and remitting tax on that direct channel, purely because the combined total crossed the line.

This is one of the most common and most expensive misunderstandings among growing e-commerce businesses: assuming that because “Amazon handles my sales tax,” the business has no sales tax exposure at all. Amazon handles tax on the transactions Amazon itself facilitates. It says nothing about a business’s direct sales, wholesale sales, or sales through any other channel — and it is precisely the combination of all channels together that determines whether the underlying registration obligation exists in the first place.

What Is a “Marketplace Facilitator,” and Does Every Platform I Sell on Qualify as One?

A marketplace facilitator is a platform that meets a state’s specific statutory definition of an entity that facilitates sales on behalf of third-party sellers and, as a result, takes on the tax collection responsibility for those specific transactions. Amazon’s standard marketplace, Etsy, and eBay are commonly treated as marketplace facilitators under most states’ laws, including California’s. But not every platform a business uses actually qualifies. Shopify’s standard e-commerce store platform, for example, is generally not a marketplace facilitator — the merchant using Shopify remains the seller of record and retains full responsibility for tax collection on those sales, even though the checkout technology looks similar to a marketplace experience from the customer’s perspective. A business selling across several different platforms needs to verify, platform by platform, which ones are actually treated as marketplace facilitators under the relevant state’s law and which ones leave collection responsibility squarely with the business itself.

Does Having Any Physical Presence at All in a State Still Matter, Now That Economic Nexus Exists?

Yes — economic nexus supplemented the physical presence rule; it did not replace it. A business can still create nexus in a state the old-fashioned way, and growing businesses frequently trigger physical presence nexus without realizing it, through activity that has nothing to do with the Wayfair economic thresholds at all. Common triggers include: storing inventory in a state, including inventory held in a third-party fulfillment warehouse (this is a particularly common trap for businesses using Fulfillment by Amazon, where Amazon may distribute a seller’s inventory across multiple state warehouses without the seller’s direct involvement in choosing which states); having even a single remote employee or independent contractor performing sales or service functions in a state; attending a trade show or maintaining a temporary sales presence; or owning or leasing any property, however small, in a state. A business can be well under every state’s economic nexus dollar threshold and still owe sales tax somewhere purely because of a warehouse pallet or a single remote hire.

What About the Income Tax Side — Does Economic Nexus for Sales Tax Also Create an Income Tax Filing Obligation?

Not automatically, and this distinction is important because sales tax nexus and income tax nexus are governed by different, independent legal frameworks. For income tax purposes specifically, a business that sells only tangible personal property, and whose in-state activity is limited strictly to the solicitation of orders that are approved and shipped from outside the state, is generally protected from a state’s net income tax under a federal law called Public Law 86-272, enacted in 1959. This protection is real, but it is also narrow and has eroded significantly as commerce has moved online. The Multistate Tax Commission has taken the position, adopted by a growing number of states, that certain routine website functionality — post-sale customer chat support, certain cookie-based tracking used for purposes beyond pure solicitation, or offering products through an app with functionality beyond simply displaying and ordering items — can exceed the narrow “solicitation” activity the statute protects, exposing the business to income tax nexus in states where it believed it was fully protected. And critically, P.L. 86-272 provides no protection at all for businesses selling services or for taxes other than a net income tax — meaning it does nothing to protect a business from sales tax collection obligations, which are governed entirely by the separate economic nexus analysis described throughout this guide.

Part Three: What Happens When Exposure Is Discovered, and How to Fix It

How Does a State Actually Find Out That an Out-Of-State Business Has Crossed Its Threshold?

States have gotten considerably better at this over the years since Wayfair, and the mechanisms are worth understanding because they explain why “no one has contacted us yet” is a poor basis for assuming there is no exposure. States cross-reference data from marketplace facilitators, who are generally required to report aggregate seller activity; they analyze 1099-K filings, which payment processors file with both the IRS and, increasingly, state tax agencies, showing gross payment volume by business; they participate in information-sharing arrangements with other states and with the Multistate Tax Commission; and they run nexus questionnaires and audit sweeps targeting industries or sales channels known for high rates of non-compliance. A business that assumes its exposure is invisible because it has never registered anywhere is, in practice, relying on a gap in enforcement that has been closing steadily for years, not on any genuine legal protection.

If We Discover That We Have Had Unregistered Exposure in Several States for a Few Years, What Are the Actual Options?

There are, broadly, three paths, and they produce dramatically different outcomes. The first is to do nothing and wait to be caught — this is the worst option by a wide margin, because most states have no statute of limitations that protects an entity that never registered at all; an unregistered business can be assessed for every year it should have been collecting, with no lookback limit, plus penalties and interest compounding the entire time. The second is to simply register today and start collecting prospectively, without addressing the past — this stops the exposure from growing further but does nothing about the liability that has already accumulated, which remains fully assessable if the state later discovers it. The third, and by far the most favorable option for a business that discovers meaningful past exposure, is a Voluntary Disclosure Agreement (VDA).

What Is a Voluntary Disclosure Agreement, and What Does It Actually Do?

A VDA is a formal agreement between a taxpayer and a state, entered into before the state has contacted the taxpayer about the specific liability, under which the business agrees to register, file returns, and pay the tax due for a limited lookback period, in exchange for the state agreeing to waive penalties for that period and, critically, to forgo assessment for any years prior to the lookback period entirely. Interest is still generally charged for the lookback period — VDAs virtually never waive interest — but the penalty waiver and the limitation on how far back the state can reach are the two features that make this program so valuable for a business with genuine, multi-year unregistered exposure.

The specific lookback period varies by state and by program, but a commonly used benchmark is three to four years, though it can run shorter or longer depending on the specific state and the taxpayer’s particular facts. For a business that has been out of compliance for six or seven years, the difference between a VDA-negotiated three-year lookback and a state discovering the full unregistered history on its own — with no limit on how far back it can assess — can represent an enormous, genuinely business-threatening reduction in exposure.

Is a VDA Available in Every State, and Does It Work the Same Way Everywhere?

No, and this is an area where a coordinated, professionally managed process matters considerably. VDA programs exist in most states, but some are codified directly in statute (as in California and Connecticut), which tends to make the terms less flexible, while others are administered at the tax agency’s discretion (as in Maryland and New York), which allows more room for negotiation based on a taxpayer’s specific circumstances. For a business with exposure in many states simultaneously, negotiating each state’s VDA individually and separately would be an enormous undertaking. The Multistate Tax Commission (MTC) operates a Multistate Voluntary Disclosure Program, coordinated through its National Nexus Program staff, that allows a single taxpayer to negotiate VDA terms with up to 37 states and the District of Columbia simultaneously, using one uniform application process rather than fifty separate negotiations. Notably, the Commission treats an applicant’s identity as confidential throughout the process — a state does not learn who the taxpayer actually is until that specific state’s VDA has been signed — which allows a business to explore and negotiate terms before committing to disclosure in any state where the numbers do not ultimately make sense.

Is There Ever a Situation Where a VDA Is Not Available or Not the Right Choice?

Yes, in a few specific circumstances. Most importantly, a VDA generally requires that the disclosure be genuinely voluntary — meaning it happens before the state has already contacted the business about that specific liability. Once a state has sent a nexus questionnaire, opened an audit, or otherwise made contact regarding the tax at issue, the voluntary disclosure door typically closes for that state, and the business is left negotiating from a considerably weaker position within whatever audit or examination process the state has already initiated. Separately, VDA programs generally do not offer penalty waivers or lookback relief for sales tax that was actually collected from customers but never remitted to the state — a materially more serious category of noncompliance than simply failing to register and collect in the first place, since the money was collected from the customer and the state views retaining it as fundamentally different from an honest failure to register.

Part Six: Additional Layers That Compound the Complexity

Does Having Remote Employees Working From Home in Other States Create Nexus, Even if the Business Has No Office There at All?

Yes, and this has become a significantly larger issue since remote work became widespread. A single employee working from their home in another state — even in a purely administrative or customer-support role with no direct sales function — generally constitutes physical presence in that state for both sales tax and income tax nexus purposes. This is easy to overlook because it does not feel like the business has “expanded” into that state in any meaningful commercial sense; from the business’s perspective, it simply hired a good candidate who happened to live somewhere else. From the state’s perspective, that employee’s presence is enough of a connection to potentially require sales tax registration if the business sells taxable goods or services, and separately to require income tax filing in that state as well. A growing business that has hired remote employees across several states over the past few years, without ever mapping those hires against a nexus analysis, often discovers this is an entirely separate and independent source of exposure from anything related to its sales volume.

Once Nexus Is Established in a State, Is That the End of the Complexity, or Does the Actual Tax Calculation Get More Complicated From There?

Establishing nexus is really just the starting point. Once a business is required to collect a state’s sales tax, it then has to navigate that state’s specific rules about what is taxable (which varies enormously — some states tax software as a service, others do not; some tax digital goods, others do not; some exempt clothing below a certain price point, others do not exempt clothing at all) and, in states that allow it, local and district tax rates layered on top of the state rate. California is a particularly clear example of this second layer: the statewide base rate is 7.25%, but cities, counties, and special taxing districts can add their own district taxes on top, pushing the combined rate in cities like Los Angeles, San Francisco, and Long Beach above 10%. A business that has correctly identified it has California nexus still has to determine the correct combined rate for every specific delivery address within the state, since district tax boundaries do not always align neatly with city or county lines.

What Is the Difference Between “Sales Tax” and “Use Tax,” and Does That Distinction Matter for a Growing Business?

Sales tax and use tax are, functionally, two sides of the same obligation, and understanding the distinction helps explain why a business cannot avoid the issue simply by structuring transactions a particular way. Sales tax is collected by the seller from the buyer at the point of sale. Use tax is owed by the buyer directly to the state when the buyer purchases a taxable item without paying sales tax at the time — most commonly because the seller was not required (or did not know it was required) to collect it. States generally impose both taxes at the same rate specifically so that a purchase does not become effectively tax-free just because it crossed state lines. For a business, this means that even in a scenario where a customer’s home state never successfully requires the seller to collect tax, the customer likely still owes use tax directly — but as a practical matter, states have found direct consumer use tax enforcement extremely difficult, which is precisely why the seller-side economic nexus framework created after Wayfair exists: it is far more efficient for a state to require a small number of sellers to collect tax on many transactions than to chase down use tax from individual consumers one purchase at a time.

If We Discover Exposure but the Dollar Amounts in a Particular State Are Genuinely Small, Is It Still Worth Pursuing a Formal VDA There?

Not always, and this is exactly the kind of judgment call that benefits from an experienced, state-by-state assessment rather than a blanket policy applied uniformly everywhere. The Multistate Tax Commission itself will not process a voluntary disclosure application through its National Nexus Program staff when the good-faith estimated tax due for the lookback period is under $500 — reflecting the practical reality that below a certain threshold, the administrative cost of a formal VDA process exceeds the benefit, and a business is generally better served simply registering and paying any minimal liability directly with that state rather than pursuing the full disclosure process. For states where the exposure is more than nominal but still modest, the right approach requires weighing the actual dollar exposure, the specific state’s VDA terms, and the administrative cost of pursuing formal disclosure against simply registering and addressing the liability directly — a calculation that looks different in every state and for every business, depending on the specific numbers involved.

Part Four: Questions Growing Businesses Actually Ask

Q: We are a small business. Do we really need to worry about this, or is this only a concern for large e-commerce companies?

A: Size is not really the relevant variable — sales volume into specific states is. A business with a single, highly successful product that happens to sell well in a handful of populous states can cross several states’ economic nexus thresholds long before it would consider itself a “large” company by any other measure. A modest business doing $150,000 a year into Texas or Florida, for example, has already crossed thresholds that many states set considerably lower than California’s $500,000 figure. Genuine growth in even one or two concentrated markets is often enough to trigger obligations most small business owners never think to check for.

Q: We sell exclusively through wholesale to other businesses, not directly to consumers. Does nexus still apply to us?

A: Generally, wholesale sales for resale are exempt from sales tax collection at the point of sale, because the tax is intended to apply when the product finally reaches an end consumer, not at each stage of a supply chain. However, this does not mean wholesale activity is entirely irrelevant to nexus — some states include wholesale and resale sales in the gross sales figure used to calculate whether the economic nexus dollar threshold has been crossed, even though those specific sales are not themselves taxable once nexus is established. A wholesale-only business can still trigger a registration obligation based on total sales volume, even if the actual tax collected once registered is minimal because most transactions qualify for a resale exemption. The registration and filing obligation, and the resale certificate documentation requirements that come with it, still apply.

Q: We use Amazon FBA (Fulfillment by Amazon) for our inventory. Can that alone create nexus, separate from our sales volume?

A: Yes, and this is one of the most common and most easily overlooked sources of physical presence nexus for growing e-commerce businesses. When a seller enrolls in Amazon’s FBA program, Amazon may store that seller’s inventory across a network of fulfillment centers in multiple states, often without the seller having direct, ongoing visibility into or control over exactly which states their inventory sits in at any given time. Because storing inventory in a state has long been recognized as a form of physical presence, a business using FBA can have physical presence nexus in states well before its sales volume into those states approaches any economic nexus threshold at all. This means an FBA seller’s actual nexus footprint often needs to be evaluated using warehouse location data pulled directly from Amazon’s own seller reporting tools, not simply by tracking sales dollars by destination state.

Q: If we register in a new state, does that create any risk of a broader audit into unrelated issues?

A: Registering itself is a routine, administrative act and does not, by itself, invite scrutiny beyond the specific tax type being registered for. What matters more is how the registration is handled — registering prospectively without addressing genuine, material past exposure in that same state can leave an unresolved liability sitting on the books that a future audit, triggered for entirely unrelated reasons, could then uncover on far worse terms than a proactive VDA would have offered. This is precisely why the sequencing matters: evaluating past exposure and deciding whether a VDA makes sense before simply registering and beginning prospective collection, rather than registering first and hoping the past liability goes unnoticed.

Q: We are considering selling our business in the next year or two. Should nexus exposure be addressed now, or can it wait until a buyer raises it during due diligence?

A: Addressing it now is almost always the better strategic choice. Sophisticated buyers, and particularly buyers backed by private equity or institutional capital, routinely include multi-state sales tax nexus review as a standard part of due diligence, precisely because unresolved exposure represents a real, quantifiable liability that a buyer does not want to inherit unknowingly. Discovering unregistered exposure during due diligence typically results in either a purchase price reduction, an escrow holdback specifically tied to the estimated liability, or, in more serious cases, a delayed or restructured transaction while the issue gets resolved. A business that identifies and resolves its exposure — ideally through a VDA that caps the lookback period and eliminates penalty exposure — well before a sale process begins controls both the cost and the narrative, rather than having a buyer’s advisors discover it and use it as negotiating leverage.

Q: How do we even begin figuring out where we might have exposure across fifty states?

A: The starting point is a comprehensive nexus study: pulling sales data by destination state across every sales channel — direct website sales, wholesale, and every marketplace platform used — for the past several years, and comparing that data against each relevant state’s specific economic nexus threshold, measurement period, and definition of what counts toward it. This needs to be layered with a separate review of physical presence indicators: inventory location data (particularly for FBA sellers), remote employee or contractor locations, and any other tangible footprint the business may have. Only once this complete picture exists — state by state, channel by channel, physical presence and economic nexus both accounted for — can a business make an informed decision about which states actually warrant a VDA, which can simply be addressed through prospective registration, and which present no meaningful exposure at all.

Part Five: How These Cases Actually Play Out

Scenario 1: The E-Commerce Brand That Assumed Amazon Had It Covered

A consumer products company selling primarily through Amazon, with a smaller direct-to-consumer website, had never registered for sales tax in any state outside California, operating for years under the belief that Amazon’s marketplace facilitator collection responsibility meant the business itself had no separate exposure. A comprehensive channel-by-channel review found that in several states, the combination of Amazon-facilitated sales and direct website sales had crossed the relevant economic nexus threshold years earlier — meaning the direct website sales in those states had been unregistered and uncollected the entire time.

Mike Habib quantified the specific exposure state by state, distinguishing clearly between the Amazon-facilitated sales (already properly taxed by Amazon as the marketplace facilitator) and the direct website sales that had never been registered or taxed anywhere. For the states with the most significant, multi-year direct-sales exposure, Mike pursued Voluntary Disclosure Agreements through the Multistate Tax Commission’s coordinated program, securing a limited three-year lookback and full penalty waivers in each participating state, rather than the business facing an open-ended assessment period if a state had discovered the gap independently.

Scenario 2: The Wholesale Distributor Surprised by a Registration Requirement Despite Selling Almost Entirely Tax-Exempt

A wholesale distributor selling almost exclusively to other businesses for resale assumed that because nearly all of its sales were exempt, no state sales tax obligation could ever apply to it. When the business began exploring expansion into several new states, it discovered that its total gross sales volume — including the exempt wholesale transactions used to measure the economic nexus threshold in several states — had already crossed multiple states’ registration thresholds.

Mike Habib walked the business through which specific states counted gross sales (including exempt resale transactions) toward the threshold versus which states measured only taxable retail sales, identifying exactly where a registration obligation actually existed despite the business collecting little or no tax in practice once registered. Registering proactively and implementing a proper resale certificate collection process for its wholesale customers resolved the compliance gap going forward, while a review of the historical exposure confirmed it was immaterial enough in the affected states that a full VDA process was not cost-justified relative to simply registering prospectively.

Scenario 3: The SaaS Company Navigating Income Tax Nexus Questions Alongside Sales Tax

A growing software company selling a cloud-based subscription product had properly registered for sales tax in the relatively small number of states that tax software-as-a-service, but had not separately evaluated whether its multi-state activity created state income tax filing obligations independent of the sales tax question. The company’s sales team included remote employees in several states, and its product involved ongoing customer support functionality that went beyond simple order solicitation.

Mike Habib evaluated the company’s income tax nexus footprint separately from its sales tax position, confirming that because the business sold services rather than tangible personal property, Public Law 86-272’s narrow protection never applied to it in the first place — a common point of confusion for growing service and software businesses that assume this federal protection covers them the same way it might cover a business selling physical products. The remote employees created clear income tax nexus in their respective states regardless of any other analysis, and the company registered and began filing the appropriate state income tax returns in those states going forward, addressing a real, previously unaddressed obligation before it compounded further.

How Mike Habib, EA Approaches Multi-State Nexus Cases

Start With a Complete, State-By-State, Channel-By-Channel Picture

Every engagement begins with pulling the actual sales data — by destination state, by channel, across the relevant historical period — and mapping it against each state’s specific threshold, measurement period, and counting rules, alongside a separate review of physical presence indicators like inventory location and remote personnel. This is detailed, data-intensive work, and it is the only way to move from a vague sense of “we probably have exposure somewhere” to a precise, state-by-state assessment of where real obligations exist and how large they actually are.

Distinguish Material Exposure From Immaterial Exposure

Not every state where a threshold was technically crossed justifies the same response. Mike Habib helps businesses distinguish between states with genuinely material, multi-year unregistered liability — where a Voluntary Disclosure Agreement is clearly worth pursuing — and states where the exposure is minor enough that simple prospective registration is the more cost-effective path, avoiding unnecessary VDA costs and administrative burden where the underlying liability does not justify it.

Coordinate Multi-State Resolution Efficiently

For businesses with exposure across several states simultaneously, Mike coordinates the disclosure and registration process — including, where appropriate, using the Multistate Tax Commission’s coordinated program to negotiate terms with multiple states through a single application — rather than requiring the business to manage separate, uncoordinated processes with each state individually.

Why Flat-Fee Representation Fits Multi-State Nexus Cases

A comprehensive nexus review and multi-state resolution can involve real, substantial work — pulling and analyzing years of sales data across dozens of states and multiple channels, then negotiating individual VDA terms with several tax authorities. An hourly billing structure creates exactly the wrong incentive here: the more states involved, the more channels to analyze, the larger the bill grows, right when a growing business is trying to invest its resources into continued growth rather than an open-ended compliance project.

What to Do Right Now

If your business has grown its multi-state sales significantly and has never conducted a formal nexus review, the most valuable thing you can do is find out where you actually stand before a state, a lender, or a prospective buyer finds out for you. If you already suspect you have unregistered exposure in one or more states, moving toward a Voluntary Disclosure Agreement before any state makes contact is the single most important timing decision available to you — that option closes permanently the moment a state reaches out first.

Multi-state nexus exposure is one of the most common blind spots for a genuinely successful, growing business — precisely because growth itself is what creates the exposure, one state at a time, often without any single dramatic moment that would have flagged the problem. A clear, complete picture of where you actually stand is the foundation for resolving it on the best terms still available to you.
