Key Takeaways
- Sales tax rules have expanded significantly following South Dakota v. Wayfair, Inc., allowing states like Connecticut to impose obligations based on sales activity, not just physical presence.
- Connecticut businesses can trigger sales tax requirements through “economic nexus,” even when selling remotely or online.
- Sales tax in Connecticut may apply to more than physical goods, including certain digital products and software-related offerings.
- Many compliance issues arise not from intent, but from businesses not realizing they’ve crossed thresholds or created new obligations.
- Reviewing where your customers are located and how your revenue is generated can help identify potential risks before they become costly problems.
Sales tax used to be relatively straightforward. If you had a physical location in a state, you collected and remitted tax there. If you didn’t, you generally didn’t have to worry about it.
That’s no longer the case. Over the past several years, sales tax rules have expanded in ways that are easy to miss. And while this is happening nationwide, it has very real implications for businesses based here in Connecticut.
Why Sales Tax Has Become More Complicated
The shift started after the South Dakota v. Wayfair, Inc. decision, which allowed states to require businesses to collect sales tax even without a physical presence.
In practical terms, that means your sales activity alone can create a tax obligation.
Connecticut follows this approach through what’s called “economic nexus.” If your business exceeds certain thresholds in the state, you may be required to register, collect, and remit sales tax, even if you’re based elsewhere or operating primarily online.
Connecticut’s current threshold is:
- $100,000 in sales and
- 200 separate transactions into the state
For many business owners, the surprise isn’t the rule itself; it’s how easy it is to cross that line without realizing it. What often gets missed is that this doesn’t stop with Connecticut. Each state has its own economic nexus thresholds, and they’re not all the same. As your business grows and you sell into other states, you may be creating sales tax obligations outside of Connecticut as well. That means it’s not just a question of whether a sale is taxable; it’s also a question of where it’s taxable and whether you’ve crossed a threshold that requires you to register in that state.
This Isn’t Just About Retail Anymore
One of the biggest misconceptions is that sales tax only applies to businesses selling physical products. In Connecticut, that’s not always true. Depending on what you offer, you may have exposure if you sell:
- Software or SaaS products
- Digital goods or subscriptions
- Certain services tied to taxable products
Since Connecticut taxes many digital goods and software-related offerings, this can pull in businesses that don’t think of themselves as “product-based” at all. That’s where we see businesses get caught off guard. They’re growing, adding new revenue streams, or expanding how they deliver services, and unintentionally stepping into sales tax territory.
Where Businesses Run Into Trouble
Most sales tax issues don’t come from intentional avoidance. They come from not realizing there was an obligation in the first place. A few common scenarios include:
- A Connecticut-based business begins selling to customers in multiple states and doesn’t realize each state has its own thresholds that may trigger registration requirements
- An online store grows past threshold levels without tracking transaction counts
- A service-based business adds a digital or software component
- A company assumes its accounting platform is “handling sales tax” automatically
The challenge is that sales tax compliance isn’t always centralized. It can sit between accounting, operations, and sales, and that’s where things fall through the cracks.
And in Connecticut, enforcement is active. The state has the authority to assess penalties, revoke permits, and require back payments if a business is out of compliance, as Place2Be Restaurants recently learned.
Don’t Overlook Use Tax
Use tax is another area where we see issues come up, especially during audits.
This applies when you purchase something taxable, but sales tax wasn’t collected at the time of the transaction. In those cases, the responsibility shifts to you to report and pay the tax directly.
Most businesses don’t do this intentionally. It’s usually a byproduct of how purchases are made, including from out-of-state vendors, online orders, or situations where tax simply wasn’t applied.
But from an audit perspective, that doesn’t change the obligation.
In Connecticut, use tax is something auditors look for specifically. If it hasn’t been tracked or reported, it can add up quickly once it’s reviewed.
What to Pay Attention to Right Now
This isn’t about overreacting or assuming you have a problem. It’s about being intentional.
If you’re a Connecticut-based business, this is a good time to step back and ask:
- Where are your customers located?
- Have your sales patterns changed over the past 1–2 years?
- Are you offering anything new that could be considered taxable?
- Do you have visibility into whether you’ve crossed any thresholds?
- Have you created sales tax obligations in other states based on where your customers are located?
You don’t need a full audit to start. But you do need a clear understanding of how your revenue flows, and where it might trigger obligations.
Why This Matters as Your Business Grows
Sales tax has shifted from a location-based issue to a growth-related issue. As your business expands, whether through new markets, new offerings, or new delivery models, your compliance requirements could expand with it.
For many Connecticut businesses, this isn’t urgent because something has gone wrong. It’s important because things are going right. Growth is what creates exposure.
If you’re not sure where your business stands, this is the kind of issue that’s much easier to address early than after the fact.
We work with businesses to identify where sales tax obligations may exist, clarify what’s required, and put practical processes in place to stay compliant without overcomplicating your operations.
