Connecticut Sales Tax Calculator 2026

How to Use the Connecticut Sales Tax Calculator

Use the Connecticut sales tax calculator when you know the pre-tax purchase price and want to estimate the sales tax and final total. For most taxable retail purchases, use Connecticut's standard 6.35% rate.

Unlike many states, Connecticut does not add local city, county, or district sales taxes. That means the general sales tax rate is the same in Hartford, Bridgeport, New Haven, Stamford, Waterbury, Norwalk, Danbury, Greenwich, and other Connecticut cities.

However, not every transaction uses the 6.35% rate. Meals and certain beverages are taxed at 7.35%, selected luxury goods can be taxed at 7.75%, short-term passenger vehicle rentals are taxed at 9.35%, and some computer/data processing or business-use software transactions can use a 1.00% rate. For exact business compliance, confirm the item category before using the calculator.

How Connecticut Sales Tax Works

Connecticut has one of the simpler sales tax rate structures in the United States. The standard statewide sales and use tax rate is 6.35%, and Connecticut does not allow local jurisdictions to add separate city, county, or district sales taxes. This means a standard taxable retail purchase generally has the same 6.35% rate anywhere in the state.

That simplicity is useful for consumers. A $100 taxable purchase in Hartford, New Haven, Stamford, Bridgeport, Norwalk, Danbury, Greenwich, or Waterbury generally uses the same state rate. A buyer does not usually need to compare city rates like they would in states such as Alabama, Arizona, Colorado, or Arkansas.

Connecticut becomes more nuanced when the product or service category changes. Meals and certain beverages have a 7.35% rate. Some luxury categories, including certain high-value vehicles, jewelry, clothing, footwear, handbags, luggage, umbrellas, wallets, and watches, can be taxed at 7.75%. Short-term passenger motor vehicle rentals can be taxed at 9.35%. Computer and data processing services and some electronically accessed canned software purchased by a business for business use can be taxed at a reduced 1.00% rate.

Connecticut also taxes certain services that are specifically listed by law. Many services are not taxable unless enumerated, but taxable service categories include selected repair, maintenance, storage, business, personal, telecommunications, and other services.

For consumers, the calculator is simple for normal purchases: use 6.35%. For businesses, the key is not local-rate lookup; the key is correct taxability classification, special rates, exemption documentation, and proper filing through the Connecticut Department of Revenue Services.

Connecticut Sales Tax Examples

Example 1: $100 purchase in Connecticut

Using Connecticut's standard 6.35% rate:

Example 2: $250 taxable purchase in Stamford, Connecticut

Using Connecticut's standard 6.35% rate:

This same general rate applies in Stamford, Hartford, Bridgeport, New Haven, Waterbury, Norwalk, Danbury, and most other Connecticut locations because Connecticut has no local sales tax add-ons.

Example 3: Reverse sales tax from a Connecticut receipt

Suppose your Connecticut receipt total is $106.35 and the tax rate was 6.35%:

Use this reverse calculation when the final receipt total includes tax and you need to estimate the original taxable price.

Major Connecticut City Sales Tax Rates

Before deployment, verify the standard rate and special-rate categories against the Connecticut Department of Revenue Services. Connecticut city rates are simple because there are no local sales taxes, but item-specific rates can change the final tax.

Why Sales Tax Does Not Vary by City in Connecticut

Connecticut sales tax does not vary by city because local jurisdictions do not impose additional city, county, or district sales taxes. The standard statewide rate is 6.35%, so a normal taxable retail purchase usually uses the same rate whether it happens in Hartford, Bridgeport, New Haven, Stamford, Waterbury, Norwalk, Danbury, or Greenwich.

This is the main difference between Connecticut and many other states. In states like Colorado or Alabama, the local city or county can dramatically change the final rate. In Connecticut, location usually matters less than the type of item or service being sold.

For shoppers, this makes Connecticut sales tax easier to calculate. For businesses, the harder part is classifying the transaction correctly. A standard retail item may be taxed at 6.35%, a restaurant meal may be taxed at 7.35%, selected luxury goods may be taxed at 7.75%, and some business-use computer/data processing services may be taxed at 1.00%.

What Is Taxable in Connecticut

Online Purchases and Remote Sellers in Connecticut

Online purchases delivered into Connecticut may be subject to Connecticut sales or use tax. Since Connecticut does not have local sales tax, the rate calculation is usually simpler than in many states. Most taxable online retail purchases use the 6.35% statewide rate unless a special product category rate applies.

Remote sellers can have Connecticut collection obligations when they meet the state's economic nexus threshold. Connecticut is commonly treated as an "and" threshold state: remote sellers generally need to exceed both $100,000 in gross receipts and 200 retail sales transactions into Connecticut during the applicable measurement period before collection is required.

Marketplace facilitators may also have Connecticut sales tax collection obligations. Marketplace sellers should verify whether the marketplace is collecting Connecticut tax on their behalf and whether any direct sales create separate registration or filing duties.

Plain-English example: if an ecommerce seller ships taxable products to Connecticut customers and exceeds both the dollar and transaction thresholds, it should review Connecticut registration requirements, collect the correct 6.35% or special rate where applicable, file returns through DRS, and keep records of taxable, exempt, and marketplace sales.

Common Connecticut Sales Tax Mistakes

• Looking for city sales tax rates even though Connecticut has no local sales tax.
• Using a local-rate calculator when the standard statewide rate is usually 6.35%.
• Applying 6.35% to restaurant meals when meals and certain beverages use the 7.35% rate.
• Forgetting the 7.75% special rate for selected luxury vehicles, jewelry, clothing, footwear, handbags, luggage, umbrellas, wallets, and watches.
• Treating software, SaaS, digital goods, or computer/data processing services as automatically exempt.
• Assuming all services are exempt, even though Connecticut taxes many specifically listed services.
• Ignoring Connecticut use tax on taxable out-of-state or online purchases.
• Forgetting that businesses must file Form OS-114 even for periods with no taxable sales if they are assigned a filing requirement.

Connecticut Sales Tax for Businesses

Businesses selling taxable goods or taxable services in Connecticut may need to register with the Connecticut Department of Revenue Services for a Sales and Use Tax Permit. Registration is required for sellers of goods, taxable services, rentals, leases, lodging, and certain temporary sellers such as craft show, trade show, flea market, or fair vendors.

Connecticut's rate structure is simpler than many states because there are no local sales tax rates. However, business compliance still requires careful product classification. A sale may be taxed at 6.35%, 7.35%, 7.75%, 9.35%, or 1.00% depending on the item or service.

Connecticut businesses generally file Form OS-114 through myconneCT. Filing frequency may be monthly, quarterly, or annual depending on the business. Businesses must report taxable and nontaxable sales according to the filing frequency assigned by DRS.

Good records should include taxable sales, exempt sales, resale certificates, service classifications, digital product sales, software/SaaS treatment, marketplace sales, remote sales, tax-free week sales, luxury-rate transactions, and use-tax accruals.

This calculator is useful for estimates, but businesses should verify exact rates, exemptions, special categories, and filing obligations through Connecticut DRS, myconneCT, official DRS publications, or a qualified tax professional.
