Are you prepared for what’s coming? Moreover, do you even know what’s heading your way?
If you’re running a business in the United States, 2026 isn’t just another year on the calendar. It’s a pivotal moment when sales tax law changes will reshape how you handle compliance, potentially saving you thousands or costing you dearly. Furthermore, these changes affect everyone from small ecommerce sellers to established brick-and-mortar retailers.
Think of sales tax law changes like shifting tectonic plates. On the surface, everything seems stable. However, beneath your business operations, fundamental rules are moving. Consequently, those who ignore these shifts risk getting caught in the earthquake. Meanwhile, smart business owners are already preparing.
This comprehensive guide breaks down the critical sales tax law changes arriving in 2026. Additionally, we’ll explore what they mean for your business and, most importantly, how to stay ahead of potential compliance disasters.
Let’s be honest. Sales tax compliance already feels overwhelming. Nevertheless, 2026 brings significant modifications that could directly impact your bottom line.
Starting in 2026, Colorado will eliminate its state sales tax vendor fee while allowing retailers to retain a small collection allowance (Sales Tax Updates | Sales Tax Tools Sales Tax institute). Meanwhile, other states are implementing their own unique adjustments. Therefore, understanding these changes isn’t optional anymore.
Here’s what makes 2026 different. First, states are simplifying some rules while complicating others. Second, technology services face increased scrutiny. Third, delivery fees are spreading rapidly. Finally, economic nexus thresholds are shifting in ways that might surprise you.
But here’s the real kicker: these sales tax law changes don’t happen in isolation. Instead, they create a ripple effect across your entire business operations. Accordingly, your current compliance strategy might become obsolete overnight.
You might be wondering, “Can’t I just use automation software and call it a day?” Unfortunately, that’s exactly where many businesses make their costliest mistake. While technology helps, it cannot replace human expertise when interpreting complex regulatory changes. For more context, check out our article on sales tax automation risks for small businesses.
Good news exists among all these changes. Specifically, several states are simplifying their economic nexus requirements.
Effective January 1, 2026, Illinois will eliminate its 200-transaction threshold, requiring remote sellers to establish economic nexus based solely on meeting or exceeding the $100,000 gross receipts threshold (US Illinois ends transaction nexus threshold sales tax 2026 – vatcalc.com). This represents a significant streamlining effort.
What does this mean practically? Previously, you needed to track both your sales revenue and transaction count. Now, you only watch one number. Consequently, compliance becomes slightly easier.
However, don’t celebrate too quickly. While Illinois simplifies, you still need to monitor thresholds across all states where you sell. Moreover, each state measures these thresholds differently.
As of July 1, 2025, fifteen states have already eliminated the 200-transaction threshold from their economic nexus laws (States eliminating economic nexus transaction thresholds in 2025 – Avalara). Therefore, the trend toward simplification is real.
Think of it this way. Remember when you needed separate keys for your house, car, office, and mailbox? Then keyless entry arrived, making life easier. Similarly, eliminating transaction thresholds removes one variable from your compliance calculations. Nevertheless, you still have multiple states to track.
Here’s what you should do now:
Additionally, understand that crossing a threshold triggers immediate collection obligations in approximately twelve states. Therefore, preparation isn’t just smart; it’s essential. Learn more about this in our guide on what is sales tax nexus.
Do you sell on Amazon, Etsy, or eBay? Then marketplace facilitator laws directly affect you.
Marketplace facilitator laws impose obligations on platforms that facilitate sales to collect and remit sales tax on behalf of marketplace sellers (State-by-state guide to marketplace facilitator laws). This sounds simple, right? Actually, it’s more complicated than it appears.
Currently, most states require marketplaces to handle tax collection for your platform sales. However, you remain responsible for sales through your own website. Furthermore, some states require you to report marketplace sales even when the platform collects tax.
Consider this scenario. You sell through Amazon and your website. Amazon collects tax for those transactions. Great! But then you realize some states want you to file zero-dollar returns. Others don’t. Meanwhile, a few states count marketplace sales toward your economic nexus threshold in other channels.
Confused yet? You’re not alone. This complexity is precisely why relying solely on automation software creates dangerous gaps. For deeper insights, read our article about marketplace facilitator sales tax laws.
Here’s what keeps tax professionals awake at night. In states where marketplace sales count toward economic nexus thresholds, marketplace transactions could help create a sales tax registration requirement for manufacturers (Key 2025 sales tax law changes: Essential insights for businesses and accounting professionals).
Let me explain this trap clearly. Imagine you manufacture products and sell them through Amazon. Amazon collects the tax, so you think you’re covered. However, those Amazon sales might trigger nexus for your direct sales. Suddenly, you need to register and collect tax for your website orders. Meanwhile, you had no idea this was coming.
Furthermore, inventory stored in marketplace fulfillment centers creates physical nexus. Therefore, even if you never visited a state, your products sitting in an Amazon warehouse might obligate you to collect tax. This represents one of the most common and costly mistakes businesses make.
Technology companies, listen up. The sales tax law changes in 2026 particularly target digital and IT services.
Beginning January 1, 2026, Washington’s expanded definition of tobacco products will include synthetically created nicotine products for tax purposes (Changes Coming to the Washington Sales Tax Landscape on October 1, 2025 | Alvarez & Marsal | Management Consulting | Professional Services). Moreover, effective October 1, 2025, Washington imposes retail sales tax on numerous information technology services including training, technical support, help desk services, network operations, data processing services, and implementation services (Washington Enacts Significant B&O and Sales Tax Changes | Forvis Mazars).
Additionally, Washington’s revised definition of digital automated services eliminates exclusions for live presentations, advertising services, data processing services, and services primarily involving human effort (Changes Coming to the Washington Sales Tax Landscape on October 1, 2025 | Alvarez & Marsal | Management Consulting | Professional Services). This massive expansion catches many businesses off guard.
Think about what this means. Previously, if your service involved significant human effort, you likely escaped taxation. Now, that protection disappears. Consequently, consultants, IT professionals, and service providers face new obligations.
Custom software and customization of pre-written software, regardless of delivery method, become taxable under Washington’s changes (Alvarez & Marsal). This represents a fundamental shift in how technology services are treated.
Here’s the catch. Different states define “software” differently. Some states tax software as a service (SaaS) while exempting custom development. Others do the opposite. Meanwhile, Washington now taxes both. Therefore, you need state-specific knowledge, not generic rules. Our guide on SaaS sales tax provides additional clarity on this complex topic.
Furthermore, sellers with existing contracts prior to October 1, 2025, aren’t required to collect sales tax until April 1, 2026, provided there’s no material change in the contract (Washington Enacts Significant B&O and Sales Tax Changes | Forvis Mazars). This grace period offers planning time, but only if you act now.
Now we enter truly controversial territory. Retail delivery fees represent an entirely new compliance burden separate from traditional sales tax.
Maryland Governor Wes Moore proposed a 75-cent fee on retail deliveries as part of his 2026 budget, expected to generate $225 million (States Eye Retail Delivery Fees to Address Gas Tax Erosion). Additionally, bills have been introduced in Hawaii for a 50-cent delivery fee and Mississippi for a 30-cent fee (States Eye Retail Delivery Fees to Address Gas Tax Erosion).
Currently, retail delivery fees are being considered by lawmakers in more than ten states, including Hawaii, Indiana, Maryland, Mississippi, Nebraska, Nevada, New York, Ohio, Oregon, Vermont, and Washington (Retail delivery fees under fire in 2025). This isn’t a passing trend; it’s a movement.
Why should you care? Because delivery fees operate differently than sales tax. First, they apply per delivery, not per item. Second, exemption rules vary wildly. Third, they require separate returns and tracking. Finally, some states let you absorb the fee while others mandate customer collection.
Let’s break down the complexity. Colorado currently charges 29 cents per order on retail deliveries involving tangible personal property subject to sales tax (The Next Frontier in Sales Tax Compliance: Retail Delivery Fees | Sales Tax Institute). Meanwhile, Minnesota charges 50 cents per order when the retail delivery transaction equals or exceeds $100 (Sales Tax Institute).
Notice the differences? Colorado charges per delivery regardless of amount. Minnesota only charges on orders over $100. Additionally, Minnesota exempts food but includes clothing. Colorado doesn’t exempt food. Therefore, you need different procedures for each state.
Moreover, Washington estimates each resident could make between 42 and 46 online retail orders for delivery in 2026, and if implemented, the fee could generate between $45 million and $112 million annually (Will Washington be the next state to implement a retail delivery fee?). With revenue projections like these, expect more states to jump on this bandwagon.
Here’s the practical challenge. You already track:
Now add delivery fees with their own rules, exemptions, and thresholds. Consequently, your compliance complexity multiplies exponentially. This is precisely why many businesses discover too late that they needed professional guidance, not just software. Explore common pitfalls in our article about (5 sales tax mistakes that could cost your business thousands).
Business and Occupation (B&O) taxes primarily affect Washington state businesses. However, the changes coming in 2026 set precedents other states might follow.
Effective January 1, 2026, Washington increases the B&O tax rate for the services and other activities classification by imposing a 1.2 percent surcharge on gross income exceeding $1 million annually (Forvis Mazars). This hits service businesses particularly hard.
Furthermore, exemptions exist for certain industries. Exemptions include taxpayers paying different surcharges such as those for advanced computing and financial institutions, plus manufacturers, sellers of manufactured goods, and fuel wholesalers and retailers (Forvis Mazars).
But here’s what matters most. If you’re a service provider in Washington earning over $1 million, your B&O tax burden just increased significantly. Additionally, you need to determine whether your business qualifies for exemptions.
This surcharge affects various service sectors differently. Consulting firms, marketing agencies, professional services, and IT companies all face increased costs. Moreover, this comes on top of the expanded sales tax requirements discussed earlier.
Think of it as a one-two punch. First, more of your services become taxable. Second, your B&O rate increases. Consequently, Washington-based service businesses face substantial new tax obligations in 2026.
Furthermore, similar to how remote employees can trigger sales tax nexus, your service activities in multiple states create complex obligations requiring careful navigation.
Now for the most important section. How do you actually prepare for these sales tax law changes?
Let’s get tactical. Here’s your action plan:
First, conduct a comprehensive nexus analysis. Review where you have physical presence, economic activity, marketplace sales, and potential obligations. Don’t guess; calculate precisely.
Second, map your products and services to new taxability rules. This goes beyond simple software categorization. You need state-specific determinations for each revenue stream.
Third, update your systems and processes. This includes your accounting software, shopping cart, and internal procedures. However, remember that technology only executes what you tell it to do.
Fourth, establish monitoring procedures. Sales tax law changes don’t stop in 2026. You need ongoing awareness of regulatory developments across all your nexus states.
Fifth, document everything. When auditors come knocking (and they will), documentation protects you. Keep records of your analysis, decisions, and implementation steps.
Here’s the uncomfortable truth that software companies won’t tell you. Automation tools are powerful, but they have critical limitations.
Software calculates rates based on addresses. Great! But it can’t determine whether your specific service qualifies for an exemption in Louisiana versus Washington. Moreover, it can’t interpret whether your manufacturing process creates nexus in Tennessee. Additionally, it can’t advise you on voluntary disclosure strategies when you discover past non-compliance.
Think of sales tax automation like a calculator. It’s an essential tool. However, you still need to know which numbers to enter and how to interpret the results. Otherwise, garbage in, garbage out. Our detailed analysis of why Avalara and TaxJar aren’t enough explains these limitations thoroughly.
Furthermore, consider this. When sales tax law changes occur, software companies update their systems. But who interprets how those changes apply to your unique business model? Who decides your compliance strategy? Who handles the gray areas where rules are ambiguous?
That’s where human expertise becomes irreplaceable. Experienced tax professionals understand:
Sales tax law changes in 2026 create both challenges and opportunities for your business. From Illinois simplifying economic nexus thresholds to Washington expanding digital service taxation, from spreading retail delivery fees to B&O tax increases, the landscape is shifting dramatically.
However, you don’t have to navigate these sales tax law changes alone. Moreover, the cost of getting compliance wrong far exceeds the investment in getting it right. Therefore, smart business owners combine powerful automation tools with expert guidance.
Think of it this way. You wouldn’t perform surgery on yourself just because medical instruments are available for purchase. Similarly, sales tax compliance for multi-state businesses requires professional expertise, especially during periods of significant regulatory change like 2026.
Don’t wait until you’re facing an audit, penalty notice, or registration requirement to seek help. Furthermore, don’t assume your current approach remains adequate as sales tax law changes take effect. Instead, take proactive steps now to protect your business.

Most sales tax law changes take effect on January 1, 2026, although some states have different effective dates. For example, Illinois eliminates its transaction threshold on January 1, 2026, while Washington’s B&O surcharge also begins January 1, 2026. However, some Washington sales tax changes for digital services took effect in October 2025. Therefore, you need to track specific dates for each state where you have obligations. Don’t assume all changes happen simultaneously.
No, this is a dangerous misconception. While marketplace platforms like Amazon collect tax for sales made through their platforms, you remain responsible for sales through your own website, at trade shows, or through other channels. Furthermore, some states require you to file returns even when marketplaces collect tax. Additionally, marketplace sales might count toward your economic nexus threshold in other states. Therefore, marketplace facilitator laws reduce some burdens but don’t eliminate your compliance obligations entirely.
Retail delivery fees operate separately from sales tax with their own rules, thresholds, exemptions, and filing requirements. They’re charged per delivery rather than per item, require separate returns, and have different exemption criteria than sales tax. For instance, Minnesota’s 50-cent delivery fee only applies to orders over $100 and exempts food but includes clothing. Meanwhile, sales tax applies per transaction with completely different exemption rules. Therefore, you need separate tracking and compliance procedures for delivery fees.
This situation requires careful handling through voluntary disclosure agreements (VDAs). Most states offer programs allowing businesses to come forward voluntarily, often with reduced penalties or lookback periods. However, timing and approach matter significantly. Coming forward voluntarily before an audit typically results in better outcomes than waiting to be discovered. Additionally, each state handles VDAs differently, so you need state-specific strategies. This represents one situation where professional guidance becomes particularly valuable, as mistakes in the disclosure process can be costly.
While automation software is essential for calculating rates and managing filings, it cannot replace professional expertise for interpreting complex regulatory changes, determining product taxability, analyzing nexus obligations, or developing compliance strategies. Software executes calculations based on the information you provide, but it cannot interpret how new laws apply to your specific business model or advise you on strategic decisions. Think of it as a powerful tool that requires expert guidance to use effectively, especially during periods of significant regulatory change like 2026.
