When the economy slows down, consumer spending slows down with it, and sales tax collections slow down right along with spending. States still have the same obligations, schools, roads, Medicaid, public safety, so a revenue shortfall doesn't make the bills disappear. It just changes where states look to close the gap. Sales and use tax enforcement is one of the first places they turn, because unlike raising rates, which requires legislative action and public buy-in, stepping up enforcement of taxes already on the books doesn't.
If your business has any nexus exposure sitting unresolved, a downturn is exactly the wrong time to leave it there.
Why States Lean Harder on Enforcement When Revenue Drops
Sales tax is one of the more visible, immediate revenue lines in a state budget, and it's also sensitive to consumer spending in a way that shows up quickly. When spending contracts, states notice the shortfall in sales tax collections faster than in some other revenue sources.
Raising the sales tax rate is politically difficult and slow, since it usually requires legislative approval. Redirecting existing audit resources toward higher-yield targets, leaning more on data-matching programs, and pursuing known noncompliance more aggressively doesn't require new legislation. It's a lever states can pull with the staff and tools they already have.
What Enforcement Tends to Look Like When Budgets Tighten
Prioritization shifts, even without new hiring. States rarely staff up meaningfully during a downturn, since hiring freezes often coincide with revenue shortfalls. What tends to change instead is where existing auditors get pointed: businesses with irregular filing patterns, industries with historically higher noncompliance, and sellers who appear to have crossed economic nexus thresholds without registering.
Greater reliance on data matching. States increasingly cross-reference sales tax filings against third-party data, including marketplace facilitator reporting and information shared through the Streamlined Sales Tax Governing Board and the Multistate Tax Commission. This kind of matching is comparatively inexpensive next to fieldwork, so it becomes more attractive when budgets are constrained.
Less appetite for informal resolution. States that might otherwise work informally with a business on a minor issue tend to lean more on formal processes, structured payment plans and voluntary disclosure agreements, when their own budget planning has less flexibility.
Faster movement once an assessment is final. A state under its own cash pressure has less patience for drawn-out collection timelines. Liens, levies, and license actions tend to move faster once a liability is finalized.
What This Means If You Have Unresolved Exposure
If you suspect you have exposure in a state, whether from an economic nexus threshold crossed without registering, or tax collected but not remitted, a downturn works against you in two ways at once. Your odds of coming forward before the state finds you get worse, not better, since enforcement activity itself increases. And the informal leniency you might expect in a stronger revenue year tends to shrink exactly when state budgets are tightest.
What to Do Before the State Finds You First
- Get a clear, current picture of where you actually have nexus. Physical presence, economic thresholds, marketplace activity. You can't prioritize what you haven't mapped.
- Estimate your actual exposure, including penalties and interest, so you're working from a real number rather than a guess.
- Move on voluntary disclosure before contact, not after. A VDA generally limits your lookback period and reduces penalties, but only if the state hasn't reached out first.
- Build compliance systems now, not after the next downturn arrives. Regular reconciliation and nexus monitoring reduce the odds you're caught flat-footed the next time enforcement tightens.
Enforcement intensity tends to track the broader economy, but exposure doesn't wait quietly between cycles, it compounds. If you're carrying unresolved risk and want a clear picture of where you stand, schedule a free What's NexT call with The Sales Tax People.

Not necessarily in raw numbers — states facing budget shortfalls often implement hiring freezes that limit audit staffing — but they do intensify enforcement in ways that increase the odds of a non-compliant business being found. The shift is one of prioritization and methodology rather than headcount. Existing auditors get redirected toward higher-yield targets: businesses with irregular filing patterns, industries with historically elevated noncompliance rates, and sellers who appear to have crossed economic nexus thresholds without registering. States also lean more heavily on data-matching programs that are far less staff-intensive than fieldwork audits, allowing them to identify potential non-filers at scale without proportionate increases in audit hours. The net effect for a business carrying unresolved exposure is that the probability of being found increases precisely when the state's tolerance for informal resolution decreases.
Sales tax enforcement is one of the few revenue levers states can pull without new legislation. Raising tax rates requires a legislative process, political consensus, and public buy-in that can take months or years. Redirecting existing audit resources toward higher-yield targets, expanding data-matching programs, and pursuing known noncompliance more aggressively can happen within the current budget cycle using staff and tools already in place. States also face a structural incentive during downturns: consumer spending contracts, which reduces organic sales tax collections, creating pressure to recover revenue from existing obligations rather than relying on future spending growth. In 2026, with 10 states projecting budget deficits, 40 states underperforming their 15-year revenue trends, and federal funding reductions adding further pressure, the conditions for intensified enforcement are directly present in the current fiscal environment.
A state tax amnesty program is a limited-time offer in which a state allows businesses and individuals with unpaid tax liabilities to come forward, pay the outstanding tax, and receive full or partial relief from penalties and interest. States typically offer amnesties when they need a quick revenue infusion without raising rates — Indiana, Illinois, and New Hampshire all offered amnesties in 2025 and early 2026 as fiscal pressure mounted. For businesses with known, quantified exposure, an amnesty can be a cost-effective way to resolve the liability. However, amnesties have important limitations: they are time-limited and unpredictable, they typically require full payment of the base tax, and they do not provide the lookback protection that a Voluntary Disclosure Agreement offers. A VDA — which allows businesses to come forward before the state contacts them, limit the lookback period, and reduce penalties — is generally a superior option when it is available, because it provides more structural protection than a time-limited amnesty program.
States have become significantly more sophisticated at identifying non-filers through data matching, which is far less expensive than traditional fieldwork and increasingly automated. Common data sources include marketplace facilitator reporting — Amazon, Etsy, and Walmart are required to report seller activity to states, allowing revenue departments to cross-reference that data against sales tax registrations and filings. States also share data through programs run by the Streamlined Sales Tax Governing Board and the Multistate Tax Commission, which allows them to identify sellers registered in other states but not their own. Payroll tax registrations that are not matched by sales tax registrations flag businesses with employees in a state but no sales tax account. Federal income tax data shared through information exchange agreements can reveal revenue flowing through states where no corresponding sales tax was filed. In 2026, states are increasingly applying AI-assisted matching tools that can process these cross-references at scale, identifying non-filer targets faster and more cost-effectively than any manual review process.
States under fiscal pressure tend to move faster through the collection process once a liability is finalized — and that acceleration shows up most clearly in lien and levy timelines. In a strong revenue year, states may show more patience with payment plan negotiations and extended timelines for resolving finalized assessments. When budgets are tight, that patience shrinks: liens are filed more quickly after assessments become final, bank levies are executed with less informal warning, and license or permit actions — including the revocation of a business's authority to collect sales tax — move faster. The practical consequence for a business with an outstanding or pending assessment is that the window for informal resolution narrows exactly when the state's own cash position is most constrained. Acting before an assessment is finalized — through a VDA, an audit appeal, or a structured payment agreement — consistently produces better outcomes than waiting until collection action has already started.
States with the tightest fiscal positions in 2026 and the most active enforcement programs include California, New York, Texas, Illinois, and Pennsylvania — all of which combine large revenue stakes, sophisticated data-matching infrastructure, and active audit programs. California in particular is known for aggressive multistate data sharing and a broad interpretation of nexus that captures many remote sellers. Texas runs one of the country's most active sales tax audit programs and has intensified enforcement of local jurisdiction under-collection given more than 900 taxing jurisdictions and over 60 new local rate changes effective in 2026. States facing specific fiscal stress in 2026 — including Colorado, Minnesota, and North Carolina, which experienced substantial rainy-day fund reductions in 2025 — are also more likely to redirect enforcement resources toward known noncompliance. For businesses operating across multiple states, the states where they have the most unresolved exposure and the weakest compliance documentation are the highest-priority ones to address.
The most important first step is to get a clear, current picture of where the exposure actually lives — which states, which periods, and what the estimated liability is including penalties and interest. You cannot prioritize or remediate what you have not mapped. Once quantified, the path forward depends on whether the state has already made contact. If no state has reached out, a Voluntary Disclosure Agreement is almost always the most favorable option: it limits the lookback period, reduces or eliminates penalties, and allows the business to come into compliance proactively before enforcement finds it. If a notice or questionnaire has already arrived, the VDA window in that state has typically closed, and the response strategy needs to be handled carefully to preserve appeal rights and avoid making admissions that expand the scope of the inquiry. In both cases, acting now rather than waiting for the next filing cycle or the next downturn is the financially rational decision: penalties and interest compound every month the liability remains unaddressed, and enforcement conditions in 2026 make the odds of being found higher than they have been in years.
