What’s taxable in Connecticut?

Services

Services include professional services provided by lawyers, architects, landscapers, etc. The definition can be pretty wide, and many exemptions can apply. Your best bet would be to check with Connecticut Department of Revenue to confirm your service is even taxable.


Tangible products

Tangible products, as you might guess, are physical items. Connecticut taxes most tangible products, but there can be exemptions! To be absolutely clear about which products are subject to sales tax, and which are exempt, check Connecticut Department of Revenue.


Digital products

Digital products are goods that are delivered or accessed electronically, usually through the internet. Media streaming services and eBooks usually fall into this category, too, but rules can vary. Check Connecticut Department of Revenue website to be sure.


Software-as-a-Service products

Better known as SaaS, these products are cloud-based software products, accessed online by customers. The definition of SaaS sometimes falls in the gray area of “digital service.” Connecticut does tax SaaS products, but check the website to confirm that the definition firmly applies to your service.


Do you have nexus in Connecticut?

The word “nexus” refers to a commercial connection in the state. Nexus determines the following questions for a state tax agency: Do you do business here, what kind, and how much? And when you do have nexus, that means you’re obligated to collect tax on your sales there.

So the first question for you to answer is whether you have nexus in Connecticut.

You probably have nexus in Connecticut if any of the following points describe your business:

  • A physical presence in Connecticut: a store, an office, a warehouse or distribution center, storage space, you, an employee, a representative, etc.
  • Online ads or links on a Connecticut-based website, which channels potential customers and new business.
  • A significant amount of sales in Connecticut within twelve months. *

* This is called an economic nexus, a sales tax nexus determined by economic activity, i.e. - the amount of sales you make in a particular state. Any kind of economic activity could trigger the nexus, once your total sales reach a certain threshold amount.

The threshold in Connecticut is $250,000 in annual sales and 200 separate sales transactions. To learn more about how this works, check out the Ultimate Guide to US Economic Nexus.


How to register for sales tax in Connecticut

Okay, so you have nexus! Now what?

The next crucial step in complying with Connecticut sales tax is to register for a sales tax permit. It’s actually illegal to collect tax without a permit. So to get all your ducks in a row, start with tax registration first.

You can find directions about how to register in Connecticut on their Department of Revenue website.

When registering for sales tax, you should have at least the following information at hand:

  • Your personal contact info
  • Your business contact info
  • Social security number (SSN) or Employer Identification Number (EIN)
  • Business entity (sole-proprietor, LLC, S-Corp, etc.)
  • Bank account info (account number and routing number) where you’ll deposit the collected sales tax

How to collect sales tax in Connecticut

Now it’s time to tackle the intricate stuff! Tax rates can vary based on the location of your business and the location of your customer, plus the levels of sales tax that apply in those specific locations.

The state-wide sales tax in Connecticut is 6.35%.

Connecticut has a destination-based sales tax system, * so you have to pay attention to the varying tax rates across the state. Charge the tax rate of the buyer’s address, as that’s the destination of your product or service.

* Important to note for remote sellers: While this is generally true for Connecticut, some state have peculiar rules about tax rates for remote sellers. Contact the state’s Department of Revenue to be sure.


Sales tax on shipping charges in Connecticut

Connecticut does apply sales tax to shipping costs. The rule of thumb is that if what you’re selling is subject to tax, then the shipping charges are also subject to tax. (And vice versa is true: If the item being shipped is not subject to sales tax, neither are the shipping charges.)

If you happen to be shipping products that are both taxable and nontaxable, then shipping charges for the entire shipment are subject to tax.


When to file taxes in Connecticut

When you register for sales tax, Connecticut will assign you a certain filing frequency. You’ll be asked to file and pay sales tax either monthly, quarterly, or annually.

Usually the frequency they choose is based on the amount of sales tax you collect from buyers in Connecticut. High-revenue businesses file more frequently than lower volume businesses, for example.

Connecticut sales tax returns are usually due on the last day of the month following the reporting period. If the due date falls on a weekend or holiday, then your sales tax filing is generally due the next business day.


How to file taxes in Connecticut

When tax time rolls around in Connecticut, whether it’s monthly or annually, you must do three things:

  1. Calculate how much sales tax you owe
  2. File a sales tax return
  3. Make a payment

Connecticut requires that any seller with a sales tax permit file a sales tax return on your due date, even if you don’t have any sales tax to report or pay. Even if you didn’t make a single sale in Connecticut during the reporting period, you should must do a “zero tax filing.”

Penalties

If you miss a filing or payment deadline, certain penalties can apply. Such a pain! Check the state’s website for up-to-date penalty fees.


Discounts

On a brighter note, you could be eligible for sales tax discounts in Connecticut! Usually these discounts are designed to save you a bit of money, as a reward for complying with the sales tax system. Check the state’s website for up-to-date discount policies.


Sales Tax Holidays

One final tricky aspect about Connecticut sales tax are the sales tax holidays. During these days of the year, you aren’t required to charge sales tax, and buyers will expect to not be charged. Check the state’s website for current sales tax holidays.
