Connecticut Sales Tax Rate 2026

Connecticut charges a flat 6.35% sales tax statewide — the same rate in every city and town. Hartford, New Haven, Stamford, Bridgeport — all 6.35%. Connecticut does not allow local governments to add their own sales taxes, making it one of the simpler sales tax states.

However, Connecticut has a unique luxury goods tax rate of 7.75% that applies to certain high-value purchases — jewelry and clothing over $1,000 per item, most motor vehicles over $50,000, and certain other luxury items. Connecticut also has a narrow clothing exemption: items under $50 per item are exempt, but items $50 and over are fully taxable at 6.35%.

Reverse Calculation Formula for Connecticut

For standard Connecticut purchases at 6.35%:

Original Price = Total Paid ÷ 1.0635

For luxury items at 7.75% (jewelry/clothing over $1,000, cars over $50,000):

Original Price = Total Paid ÷ 1.0775

Tax Amount = Total Paid − Original Price

One formula covers all standard Connecticut purchases — no city or county lookups needed.

Step-by-Step Examples

Example 1 — Electronics in Hartford (6.35%): $530.63

Total paid: $530.63. CT rate: 6.35%. Tax factor: 1.0635. Pre-tax price: $530.63 ÷ 1.0635 = $499.00. Tax: $530.63 − $499.00 = $31.63. Verify: $499.00 × 1.0635 = $530.69 ✓ (rounding)

Example 2 — Restaurant in New Haven (6.35%): $84.44

Example 3 — Luxury jewelry in Stamford (7.75%): $2,155.00

Connecticut City Reference — All 6.35%

Connecticut's Luxury Tax Rate — 7.75%

Connecticut is one of the few US states with a dedicated luxury goods tax rate. Items that trigger the 7.75% rate instead of 6.35%:

Items taxed at 7.75%

• Jewelry and watches — items priced at $1,000 or more per item
• Clothing and footwear — items priced at $1,000 or more per item
• Motor vehicles — vehicles with a sales price over $50,000
• Boats and vessels — boats with a sales price over $100,000
• Aircraft — aircraft over certain value thresholds

How the luxury rate works

The 7.75% applies to the full purchase price — not just the amount over the threshold. A $1,200 diamond necklace is taxed at 7.75% on the entire $1,200 — not just the $200 above the $1,000 threshold. This is different from Massachusetts's clothing exemption, where only the amount above $175 is taxable.

Example: $1,500 watch in Stamford — full 7.75% applies. Tax = $1,500 × 7.75% = $116.25. Total = $1,616.25. Reverse: $1,616.25 ÷ 1.0775 = $1,500.00 ✓

Example: $900 watch in Stamford — standard 6.35% applies (under $1,000). Tax = $900 × 6.35% = $57.15. Total = $957.15.

Connecticut's Clothing Exemption — Under $50 Per Item

Connecticut has the narrowest clothing exemption among the northeastern states — only clothing and footwear items under $50 per item are exempt. Items $50 and over are fully taxable at 6.35% (or 7.75% if over $1,000).

Connecticut clothing tax tiers

Compare Connecticut's $50 threshold to neighboring states: New Jersey exempts all clothing regardless of price, New York exempts clothing under $110, Massachusetts exempts clothing under $175, and Pennsylvania exempts all clothing. Connecticut's $50 threshold is the most restrictive in the region — most clothing items are taxable.

For Connecticut Business Owners

Connecticut Sales and Use Tax Return (OS-114)

Connecticut businesses file Form OS-114 with the Department of Revenue Services (DRS). Returns are filed monthly, quarterly, or annually depending on tax liability. Because the rate is flat statewide (with the luxury rate exception), filings are relatively straightforward — but businesses selling clothing must track the $50 and $1,000 thresholds carefully, and luxury goods sellers must flag high-value transactions for the 7.75% rate.

Permit to collect sales tax.

Connecticut businesses must obtain a Sales and Use Tax Permit from the DRS before collecting sales tax. This is obtained online and is required before making any taxable sales. The permit must be displayed at the business location.

Economic nexus

Connecticut's economic nexus threshold is $100,000 in annual sales or 200 transactions. Remote sellers crossing either threshold must register for Connecticut sales tax. Connecticut was one of the earlier states to implement economic nexus rules after the Wayfair ruling.

Luxury rate compliance

Businesses selling jewelry, high-end clothing, or luxury vehicles must have systems in place to automatically apply 7.75% to qualifying purchases. POS systems should flag items at or above $1,000 (for jewelry/clothing) and $50,000 (for vehicles) to trigger the correct rate. Failure to apply the luxury rate results in undercharging customers and underpaying the state.

Excel Formula for Connecticut Sales Tax

For standard Connecticut at 6.35%:

=A2/1.0635

For luxury items at 7.75%:

=A2/1.0775

For mixed receipts with both standard and luxury items:

=IF(B2>=1000, A2/1.0775, IF(B2<50, A2, A2/1.0635))

Where B2 is the pre-tax item price — this formula applies the correct rate based on price tier.

Common Mistakes with Connecticut Sales Tax

• Using the $50 clothing threshold incorrectly. Connecticut exempts clothing under $50 — not $50 and under. A $50.00 item is taxable; a $49.99 item is exempt. The threshold is strictly under $50, making $49.99 the highest price for tax-free clothing.
• Not applying the 7.75% luxury rate on jewelry over $1,000. A $1,200 necklace should show 7.75% tax ($93.00), not 6.35% ($76.20). The 7.75% applies to the full purchase price — not just the amount over $1,000. Sellers who apply 6.35% to luxury items are undercharging and underremitting.
• Applying the luxury rate to the excess only. Unlike Massachusetts, where only the amount over $175 is taxable, Connecticut's luxury rate applies to the entire purchase price once the threshold is crossed. A $1,001 item is taxed at 7.75% on the full $1,001 — not just $1.
• Thinking most clothing is exempt. Connecticut's $50 threshold is very low — the vast majority of clothing items (jeans, shoes, jackets, dresses) are $50 or more and therefore taxable. Connecticut is not a good state for tax-free clothing shopping compared to New Jersey or Pennsylvania.
• Forgetting that soft drinks are taxable at grocery stores. Connecticut exempts grocery food but not soft drinks and candy. A grocery receipt will show tax on soda and candy but not on food — separating these correctly is important for business bookkeeping.

Connecticut vs Neighboring States

Connecticut at 6.35% is lower than Rhode Island (7%), Massachusetts (6.25% — very close), New York (8.875% in NYC), and New Jersey (6.625%). For cross-border shopping, Connecticut's main competitor is New Hampshire — which charges no sales tax at all.

Many Connecticut residents shop in New Hampshire for electronics, appliances, and clothing — the NH border is accessible from northern Connecticut. For luxury goods specifically, New Jersey's unlimited clothing exemption makes it superior to Connecticut for high-end apparel shopping, even accounting for the drive.
