2026 Tax Changes - States Are Getting More Aggressive

If you thought state tax compliance was complicated before, the 2026 tax changes are making it even more challenging. States are facing serious budget problems, federal funding is getting cut, and tax departments are using new technology to find businesses that aren’t compliant.

The result? More aggressive enforcement, tighter rules, and a much higher chance of getting caught if you’re not registered where you should be.

Here’s what’s changing and why it matters for your business.

The biggest driver of increased tax enforcement in 2026 is simple: states need money.

After years of strong revenue during the pandemic, many states are now dealing with budget shortfalls. At least 10 states are facing challenging fiscal situations, with another 13 in conditional status where things could go either way.

Here are some examples:

California is dealing with a $12 billion shortfall. The state blames federal tariff policies, stock market declines, and inflation fears.

Illinois reduced its revenue forecast by $500 million due to uncertainty around federal funding cuts and weakening consumer confidence.

Indiana faces a $2 billion shortfall. Lawmakers had to raise cigarette taxes, cut funding, and spend down reserves just to balance the budget.

Iowa’s revenue dropped from $9.76 billion to $9.13 billion in one year. That’s a 6.4% decrease, and it’s expected to drop another 6.9% in 2026.

Nebraska has a $432 million shortfall, and some lawmakers are calling to pause planned income tax cuts to avoid making the problem worse.

These aren’t small numbers. And when states run short on money, they look for new revenue sources. Sales tax enforcement becomes a top priority.

The budget pressure is getting worse because of cuts to federal funding.

The federal government provides a lot of money to states for programs like Medicaid and SNAP (food assistance). But those funding formulas are changing, and states are going to have to cover more costs themselves.

What’s coming:

New Medicaid work requirements start in January 2027. This will increase administrative costs for states right away.

States’ share of SNAP costs goes up in October 2026, with more cost increases coming in 2027.

Colorado estimates an additional $10.7 million needed just for SNAP administration in 2027.

Arizona requested $75.8 million in new recurring funds starting in 2027 to manage federal policy changes.

Some estimates show states could face cuts of $880 billion in Medicaid funding and $230 billion in SNAP over 10 years.

When federal money disappears, states have three choices: cut services, raise taxes, or enforce existing taxes more aggressively. Most states are choosing option three.

States aren’t just auditing more businesses. They’re getting smarter about how they find non-compliant sellers.

Here’s what’s happening:

Data sharing between states: States are working together now. Illinois requests sales data for neighboring states during their audits. If you’re audited in one state, your information might be shared with five other states. They’re specifically targeting the Great Lakes region and other regional partnerships.

Pre-audit questionnaires: Many states are sending letters to businesses that aren’t even registered yet. They’re asking for three years of sales data. These aren’t friendly requests. States send these because they already suspect you owe them money. States doing this most aggressively include Washington, Minnesota, Illinois, California, and New York.

AI and automated matching: States are using artificial intelligence to identify non-compliant businesses. New York and other states are testing AI-driven audit selection. The technology cross-matches data from marketplaces, payment processors, and tax returns to find businesses that should be collecting tax but aren’t.

Marketplace data access: States have partnerships with platforms like Amazon. They’re getting detailed seller data and comparing it to their registration lists. If you’re selling on Amazon but not registered in a state, they know.

Stricter documentation standards: States like Florida are applying extremely strict rules about exemption certificates and resale certificates. Even if a transaction qualifies for exemption, you can lose the exemption in an audit if your documentation isn’t perfect.

The bottom line: the days of flying under the radar are over. If you have nexus and aren’t registered, states will find you.

One trend that’s been building for years is continuing in 2026: states are dropping their transaction thresholds.

Back when South Dakota v. Wayfair was decided in 2018, most states adopted a two-part test: $100,000 in sales OR 200 transactions. The idea was to catch both high-volume sellers and high-dollar sellers.

But transaction thresholds created problems. They were hard to track, they caught a lot of small sellers, and they didn’t actually generate much revenue.

States that have already dropped transaction thresholds: - Utah (July 2025) - Indiana - North Carolina - Wyoming - New Jersey - Illinois (January 2026)

Now the trend is toward simple, revenue-only thresholds. Most states use $100,000 in annual sales. Some use higher thresholds like $500,000 (California) or $250,000 (New York, Arkansas for corporate income tax).

Why this matters:

If you sell expensive items with low transaction counts, you might now have nexus in states where you didn’t before.

On the positive side, you only need to track one number per state (total sales) instead of two numbers (sales and transactions).

But don’t think this makes compliance easier overall. States are still adding complexity in other ways.

States are constantly expanding what they tax. This is an easy way to increase revenue without raising rates.

Digital products and services are a major focus in the 2026 tax changes:

Maine added digital audiovisual works and digital audio works to its taxable services starting January 1, 2026. This includes streaming services (Netflix, Hulu, Disney+), music streaming (Spotify, Apple Music), and audiobook and podcast subscriptions.

Louisiana is clarifying and expanding its digital product taxability rules with updated guidance issued in 2025.

New York continues exploring a tax on streaming services, though it hasn’t passed yet.

Chicago proposed new taxes on cloud services, online sports betting, and even social media for its 2026 budget.

Other taxability changes:

Arkansas removed the state sales tax on food for human consumption. However, local taxes might still apply.

Utah is expanding sales tax on certain prepared and customized foods sold through convenience stores and grocery channels.

Ohio repealed several exemptions including advertising materials, certain copyrighted films, and a 25% refund for electronic information services.

Why this matters:

If you sell digital products, SaaS, streaming services, or online subscriptions, you need to review taxability rules state by state. What’s exempt in one state might be fully taxable in another.

Product classification is becoming more important. The same item might be classified differently depending on its ingredients, format, or delivery method.

Don’t forget about corporate income tax. Several states are establishing or changing economic nexus thresholds for income tax, not just sales tax.

Arkansas adopted a $250,000 economic nexus threshold for corporate income tax starting January 1, 2026. If your Arkansas-sourced receipts exceed $250,000, you have corporate income tax nexus even without physical presence.

Arkansas also switched to market-based sourcing for services and intangibles. This means they look at where your customer is located, not where you perform the service.

Massachusetts updated its corporate nexus rules to address internet-based activities and businesses claiming protection under P.L. 86-272.

New York City issued proposed regulations addressing economic nexus and P.L. 86-272 for the Business Corporation Tax.

This is separate from sales tax nexus. You could owe state corporate income tax in states where you don’t collect sales tax. Most businesses don’t realize this until they get a notice from the state.

With all this increased enforcement, amnesty programs become extremely valuable.

Several states are offering amnesty in 2025-2026. These programs let you pay back taxes without the usual penalties and interest. Some states also offer simplified rates that make compliance easier.

Why amnesty matters now:

States are finding non-compliant sellers faster than ever. If you have exposure, it’s better to come forward voluntarily through amnesty than to wait for an audit.

Penalties can be devastating. Some states charge 5-25% penalties on top of the tax owed. Interest can run 3-12% per year. Over multiple years, penalties and interest can exceed the actual tax.

Once an audit starts, you lose negotiating power. Amnesty programs typically offer the best terms you’ll ever get.

Amnesty programs available in 2025-2026:

Illinois has three amnesty programs. One for general taxes, one for franchise tax, and one specifically for remote retailers starting August 2026. [Link to your detailed Illinois article here]

New Hampshire ran an amnesty from December 2025 to February 2026 that waived penalties and more than 50% of interest.

Iowa is establishing an amnesty program that must conclude by January 2027, with details still being finalized.

Other states run amnesty programs periodically. Check with your state’s Department of Revenue to see if one is coming.

If your state doesn’t have amnesty:

Consider a Voluntary Disclosure Agreement (VDA). These programs exist in most states year-round. VDAs typically offer: - Limited lookback periods (usually 3-4 years instead of unlimited) - Waived penalties (but not always interest) - Protection from criminal prosecution - A clear path to compliance going forward

The key is to act before the state finds you. Once they send you a notice or start an audit, VDA options disappear.

Some businesses still think they can avoid registration and hope they don’t get audited. That strategy is much riskier in 2026 than it was even two years ago.

Here’s why:

States have better tools. AI-powered audit selection, marketplace data sharing, and interstate cooperation mean states find non-compliant sellers much faster.

Lookback periods are long. If you never registered, many states can go back to your first sale with no time limit. That could be 5, 7, or 10 years of back taxes.

Penalties compound. A $50,000 tax liability can easily become $75,000 or $100,000 with penalties and interest. Washington State charges up to 39% in penalties. That’s money straight out of your profit.

Criminal prosecution is possible. While rare, some states can pursue criminal charges for willful tax evasion. Amnesty programs specifically protect against this. Regular audits don’t.

Audits are time-consuming and expensive. Even if you eventually win an audit, the process takes months or years. You’ll need professional representation. Your staff will spend dozens of hours pulling records. The disruption to your business is significant.

Other states will find out. Remember, states share information now. An audit in Illinois might trigger inquiries from Michigan, Indiana, Wisconsin, and Ohio.

Real example: A seller with $500,000 in annual sales across 10 states who hasn’t registered anywhere could owe $200,000-300,000 in back taxes, plus $50,000-100,000 in penalties and interest. That’s enough to put a small business out of business.

Compare that to the cost of registering and staying compliant going forward. For most businesses, the monthly cost of compliance is a few hundred dollars. The cost of getting caught is catastrophic.

If you’re not sure whether you need to worry about nexus in various states, here are the questions to ask:

Sales tax nexus: - Do you have more than $100,000 in sales into any state in a 12-month period? - Do you have employees working remotely in other states? - Do you store inventory in other states (including Amazon FBA warehouses)? - Do you have sales people traveling to other states? - Do you attend trade shows in other states?

If you answered yes to any of these, you likely have nexus somewhere.

Income tax nexus: - Do you have employees or contractors in other states? - Do you own or rent property in other states? - Do you have significant sales into states with economic nexus thresholds for income tax?

Income tax nexus can exist even when you don’t have sales tax nexus.

The compliance landscape is changing fast. Here’s your action plan for navigating the 2026 tax changes:

1. Let us help you conduct a comprehensive nexus review

Review where you have nexus right now: - Physical nexus: employees, offices, inventory, trade shows, contractors - Economic nexus: sales exceeding state thresholds - Affiliate nexus: related companies creating nexus on your behalf - Click-through nexus: affiliates driving sales to you

Don’t just look at sales tax. Check corporate income tax nexus too.

2. Let’s calculate your exposure if you’re not compliant

For each state where you have nexus but aren’t registered: - How long have you had nexus? - What’s your total taxable sales? - What’s the tax rate? - Estimate penalties and interest

This tells you how big the problem is and helps you prioritize which states to address first.

3. We can monitor amnesty programs and VDA opportunities

Set up alerts for: - Amnesty programs in states where you have exposure - VDA programs as a backup option - Changes to state nexus rules that might affect you

If you have significant exposure in Illinois, the August 2026 remote retailer amnesty program could save you a lot of money.

4. We’ll fix your registration and filing processes

For states where you need to register: - Register properly (some states have separate registrations for state and local taxes) - Set up correct tax calculation (including local taxes) - Schedule filing deadlines (monthly, quarterly, or annual depending on the state) - Keep proper documentation for exemptions and resale certificates

5. Let us help you implement better systems and controls

Manual tracking doesn’t work anymore. Consider: - Automated tax calculation software that updates rates automatically - Nexus monitoring tools that alert you when you cross thresholds - Automated filing services to avoid missing deadlines - Document management systems for exemption certificates

6. Get started

We can: - Conduct nexus studies to identify exactly where you need to register - Help you evaluate amnesty vs. VDA vs. current registration - Negotiate with states on your behalf - Represent you in audits

The cost of hiring us is nothing compared to the cost of major penalties or a full-scale audit in multiple states.

7. Document everything

Keep records of: - When you first made sales into each state - When you crossed economic nexus thresholds - All registration dates - All exemption certificates - All correspondence with state tax departments

Good documentation can reduce penalties if you’re audited and proves you acted in good faith.

The state tax compliance environment is more challenging in 2026 than it’s ever been. States need revenue, federal funding is declining, and enforcement technology is getting better every month.

But there’s good news too:

Rules are getting simpler in some ways. Transaction thresholds are disappearing. Some states are offering amnesty programs with generous terms.

If you act now, you can get compliant before problems arise. Amnesty and VDA programs exist specifically to help businesses come forward voluntarily.

The worst thing you can do is nothing. States are actively looking for non-compliant sellers. Data sharing and AI-powered enforcement mean they will find you eventually.

The choice is simple:

Come forward now on your terms, pay what you owe, and get penalties waived. Or wait and deal with audits, full penalties and interest, and potential exposure in multiple states at once.

Key takeaways from the 2026 tax changes: - State budget problems are driving much more aggressive tax enforcement - Technology (AI, data sharing, marketplace partnerships) makes hiding impossible - Economic nexus thresholds are simplifying, but enforcement is intensifying - Digital products and services are becoming taxable in more states - Corporate income tax nexus is expanding separate from sales tax - Amnesty programs offer the best terms you’ll get, but windows are short - Professional help pays for itself many times over

The businesses that thrive in 2026 will be the ones that treat sales tax compliance as a priority, not an afterthought.

Don’t wait for a letter from a state tax department. By then, your options are limited and expensive.

Get compliant now, protect your business, and focus on growth instead of audit defense.
