Connecticut’s sales tax system is a little different from many other states, and it’s important for businesses to understand the rules so they can stay compliant and avoid surprises. Whether you’re just getting started or expanding into Connecticut for the first time, this guide walks you through everything you need to know, from how sales tax works in the state to registration, filing, payment, deadlines, and more. Our goal is to help you navigate sales tax with confidence, so you can focus on running your business instead of stressing over compliance.
What is the Connecticut sales tax?
Connecticut has a single statewide sales tax rate of 6.35%. Unlike some states that layer city, county, or local district taxes on top of a base rate, Connecticut keeps things simple. No matter where you do business in the state, the standard rate is the same.
That said, Connecticut does apply different rates for specific goods. A few categories are taxed at a higher rate, including:
- 7.75% on luxury items like certain motor vehicles, jewelry, and clothing or footwear priced over $1,000
- 1% on computer and data-processing services
- Meal tax add-on: Prepared meals, certain beverages, and restaurant sales include an additional 1% “Meals Tax,” bringing the effective rate to 7.35%
Because Connecticut uses both a general rate and item-specific rates, it’s important for businesses to understand which category their products or services fall into. Applying the correct rate helps you avoid under- or over-collecting sales tax and keeps you compliant with the Connecticut Department of Revenue Services (DRS).
How to calculate sales tax in Connecticut?
Calculating sales tax in Connecticut is straightforward because the state doesn’t use local add-on taxes. In most cases, you’ll apply the 6.35% statewide rate to the price of a taxable item or service. If you sell goods that fall into one of Connecticut’s special-rate categories, you’ll apply the rate assigned to that item instead, such as 7.75% for certain luxury goods or 7.35% for meals.
Your point-of-sale (POS) system should automatically apply the correct rate once you’ve categorized your products. For example, if you sell a taxable item for $50 at the standard 6.35% rate, the sales tax would be $3.18, for a total of $53.18.
Use our reverse sales tax calculator
Some businesses, especially restaurants or retailers that include tax in the listed price, need to work backward to find the pre-tax amount. A reverse sales tax calculator makes this simple. Enter the Connecticut tax rate, the desired final price, and the tool will show you the actual sale amount before tax.
What is subject to sales tax in Connecticut?
In Connecticut, most retail sales of tangible personal property and a wide range of taxable services are subject to the state’s 6.35% sales tax. If your business sells physical goods, prepared meals, or certain listed services, you’ll generally need to collect and remit sales tax. While there are exemptions (we’ll cover those later), here’s a clear look at what Connecticut typically considers taxable:
- Most physical goods sold at retail, such as electronics, appliances, furniture, home goods, and everyday consumer products.
- Prepared meals and beverages, including restaurant food, takeout, deli items, and food meant for immediate consumption.
- Certain services, especially those specifically listed in Connecticut law, like repair and maintenance services, janitorial and landscaping services, and various business-support services.
- Digital products and software, when they fall under Connecticut’s definitions of taxable digital goods or software-as-a-service.
- Special-rate or luxury items, which may be taxed at the standard rate or higher depending on category and price thresholds.
Does Connecticut have sales tax on clothing?
Connecticut taxes most clothing and footwear at the standard 6.35% sales tax rate. Everyday apparel, from T-shirts and jeans to winter coats and children’s shoes, generally follows this statewide rate without any special rules.
However, Connecticut does apply a higher tax rate to certain high-priced items. This includes:
- Luxury clothing or footwear priced over $1,000 per item
- Handbags, luggage, wallets, umbrellas, and watches priced over $1,000
- Jewelry priced over $5,000
These items are considered luxury goods and are taxed at 7.75% instead of the standard rate.
For retailers, that means most clothing will be taxed at 6.35%, but higher-value items must be rung up at the 7.75% rate. Making sure your POS system is set up to distinguish between these thresholds can help ensure you’re charging the correct tax every time.
Connecticut sales tax rate on food and beverages
Connecticut taxes food differently depending on whether it’s grocery items or prepared meals intended for immediate consumption. This distinction matters for restaurants, food trucks, cafés, and even grocery or convenience stores that sell a mix of items.
Groceries
Most grocery staples are exempt from sales tax. Items like produce, dairy, pantry goods, and beverages such as bottled water generally fall outside the sales tax rules when they’re meant for home use.
But the moment food is hot, prepared, or packaged in a way that suggests immediate consumption, it’s often considered a taxable prepared meal, even if you find it at a grocery store.
Prepared meals (taxed at 7.35%)
Prepared meals are subject to Connecticut’s “Meals Tax,” which adds a 1% surcharge on top of the standard 6.35% rate, creating an effective rate of 7.35%. This applies to:
- Restaurant and food truck meals
- Takeout and delivery orders
- Hot deli items from grocery stores
- Certain beverages served with meals, like fountain drinks
If your business prepares food to be eaten right away, most of what you sell will fall under this higher rate.
Grocery items that are still taxable
Connecticut also taxes certain ready-to-eat or small-portion grocery items that consumers often assume are exempt. A few examples include:
- Sandwiches, wraps, and grinders, whether hot or cold
- Slices of pizza or pies, and whole pizzas
- Ice cream cones, sundaes, and individual servings of frozen desserts
- Small salads (8 ounces or less), whether greens-based or not
- Donuts, muffins, pastries, or cookies, when sold in small quantities
- Hot dogs, heated or served on a bun
- Cooked chicken or ribs, whether by the piece or as part of a family meal
- Smoothies and certain snack foods, especially when packaged in small single-serving sizes
These items are considered prepared or portioned for immediate consumption, which places them in the taxable category even when sold in a grocery environment.
For the complete list of taxable items and detailed definitions, businesses can refer to Connecticut’s official guidance on sales tax for meals from the Department of Revenue Services.
Whether you’re running a grocery store with a mix of taxable and exempt items or operating a restaurant or food truck that charges the meals tax on every order, keeping track of Connecticut’s rules can be time-consuming. DAVO by Avalara sets aside the exact sales tax you collect each day and files and pays it to the Connecticut Department of Revenue Services on your behalf. This helps you stay accurate, avoid missed deadlines, and focus more on your customers, not tax paperwork.
What items are exempt from sales tax in Connecticut?
Connecticut exempts a variety of everyday goods and essential services from sales tax to help reduce costs for residents. Most exemptions focus on necessities, health-related products, and certain life-essential services.
Common Connecticut sales tax exemptions include:
- Most grocery items intended for home consumption
- Prescription medications and many over-the-counter drugs
- Medical equipment such as walkers, wheelchairs, and certain durable medical devices
- Newspapers and magazines sold by subscription
- Utilities for residential use, including electricity, gas, and heating fuel
- Certain manufacturing equipment and machinery
- Digital goods that fall under exempt categories, such as specific educational materials
While Connecticut does exempt many categories, not all items that feel “essential” qualify. Prepared meals, candy, carbonated beverages, and small-portion grocery items are still taxable.
Because exemption rules can be specific and sometimes nuanced, retailers should review the Connecticut Department of Revenue Services tax exemption guidance when unsure. Keeping accurate records and understanding exempt categories ensures you apply the right tax at checkout and stay compliant.
Connecticut sales tax on services
Unlike many states that tax only tangible goods, Connecticut also taxes a wide range of services. If your business provides one of these services, you’re required to collect and remit sales tax on the full charge for that service. Examples of common taxable services in Connecticut include:
- Professional and business services, such as advertising, public relations, business consulting, and credit reporting
- Digital and technology services, including computer and data-processing services, website hosting, and electronically delivered canned software
- Personal services, such as dry cleaning, nail services, spa services, pet grooming, and photography studio services
- Repair and maintenance services, ranging from motor vehicle repair and towing to electrical, appliance, and electronics repair
- Home and property services, including landscaping, janitorial work, extermination, and certain contractor services
- Recreation and membership services, such as health and athletic club memberships and yoga classes offered at yoga studios
- Transportation and parking services, including livery, limousine services, and most paid parking
- Storage services, including self-storage units, boat storage, and storage of personal property
Connecticut taxes many other services as well. Businesses offering any type of service should review the state’s full guidance on taxable services to confirm whether their activities fall under taxable categories.
How to manage tax-exempt sales in Connecticut?
In Connecticut, every sale is considered taxable unless you can document why tax wasn’t collected. If your business makes exempt sales, you’ll need to gather the right paperwork and keep it on file.
Buyers must provide a proper Connecticut exemption certificate, such as CERT-119 for exempt organizations or CERT-123 for resale purchases. Make sure the certificate is complete, accurate, and applicable to the sale. The business owner must keep a copy of the exemption certificate as proof of the exempt transaction. If the certificate is missing or invalid, the tax liability could fall on you.
Only accept certificates when they reasonably apply to the transaction. This helps protect your business from penalties or interest if the exemption is later questioned.
Keeping clean records and verifying certificates upfront is the best way to stay compliant and avoid unexpected assessments. For more details on managing exemptions, visit Connecticut’s Department of Revenue’s website.
Connecticut sales tax-free week
Each year, Connecticut hosts a Sales Tax Free Week, typically in mid-August, giving shoppers a temporary break from sales tax on certain back-to-school essentials. During this week, most clothing and footwear items priced under $100 are exempt from the state’s 6.35% sales tax. The exemption applies whether purchases are made in-store or online, making it easier for shoppers to save regardless of where they buy.
Most everyday clothing and footwear intended to be worn on the body qualify for the exemption as long as each item costs less than $100 after any coupons or discounts are applied. There’s no limit to how many eligible items a customer can buy. If each piece is under the threshold, the purchase is tax-free.
Some items fall outside the exemption, even if they cost less than $100. These include:
- Athletic or protective gear (like cleats or safety boots) designed for a specific activity
- Accessories such as jewelry, handbags, watches, wallets, umbrellas, and luggage
These products remain taxable regardless of price.
The exemption applies based on when the customer pays for the item, not when it’s delivered. If the item is fully paid for during Sales Tax Free Week, it qualifies, even if it’s shipped later. If the purchase is completed before the holiday but delivered during the week, tax still applies.
Discounts and coupons can bring an item under $100 and make it eligible. However, rebates do not reduce the sales price for exemption purposes. Visit the Connecticut Department of Revenue Services website for more information on the annual sales tax-free week.
How to apply for a Connecticut sales tax license?
Any business that sells taxable goods or services in Connecticut must register for a sales and use tax license before making sales. The state requires that all new businesses must register online through the state’s online tax portal, myconneCT.

How to pay Connecticut sales tax?
All Connecticut sales tax payments must be made electronically through myconneCT. After you file Form OS-114, the system guides you directly to the payment page so you can submit your payment in the same session.
Direct payment through myconneCT

Connecticut sales tax due dates
Connecticut sales tax returns are due on or before the last day of the month following the end of your filing period. Your filing frequency is assigned by the Department of Revenue Services based on your sales volume.
Filing deadlines
- Monthly filers: Due on the last day of the following month
- Quarterly filers: Due on the last day of the month after the quarter ends
- Annual filers: Due on the last day of the month following the end of the year
If a due date falls on a weekend or state holiday, your deadline automatically shifts to the next business day.
Connecticut does not offer a vendor discount for collecting and remitting sales tax on time. If you operate in multiple states, some may provide this incentive. You can refer to our sales tax discount guide to see where you might qualify for savings. With DAVO, this collection allowance is returned to the business in full, sometimes covering the full subscription cost to DAVO.
What are the penalties for filing Connecticut sales tax late?
If you file or pay your Connecticut sales tax late, the state imposes both interest and penalties. These charges can add up quickly, so staying on schedule is important.
Interest
Late payments accrue interest at 1% per month or part of a month, starting from the original due date until the tax is paid in full. Interest is calculated on the amount that should have been remitted on time.
Penalty for late or nonpayment
If you don’t pay your sales tax by the deadline, Connecticut charges a penalty of 15% of the tax due or $50, whichever is greater.
Penalty for failing to pay electronically
Connecticut requires sales tax to be paid electronically. If you submit a payment by an unauthorized method, the following penalties apply:
- First offense: 10% of the required payment, up to $2,500
- Second offense: 10% penalty, up to $10,000
- Third and subsequent offenses: 10% penalty with no cap
Filing and paying electronically through myconneCT helps you avoid these charges and stay compliant.
