Connecticut runs a graduated state income tax in 2026, with rates from 2% up to 6.99% depending on how much you earn, on top of federal income tax and FICA. Use the calculators below to see your exact 2026 take-home pay in Connecticut, check the sales tax on a purchase, and estimate a mortgage payment with Connecticut property taxes factored in.
State Paycheck Calculator 2026
Estimate take-home pay after federal tax, FICA and your state’s income tax for the 2026 tax year.
How it works: the 2026 federal standard deduction ($16,100 single, $32,200 married filing jointly) comes off your salary first, then the 2026 federal brackets (10%–37%). FICA is applied properly: 6.2% Social Security on the first $184,500 of wages (2026 wage base), 1.45% Medicare on all wages, plus 0.9% additional Medicare on wages above $200,000 single / $250,000 married filing jointly. State tax applies each state’s own standard deduction/exemptions, then its brackets or flat rate. Local income taxes are not included — many cities and counties (e.g. New York City, Philadelphia, most of Ohio, Maryland counties, Indiana counties, Kentucky) levy their own payroll taxes on top of the state tax.
Connecticut sales tax calculator
The statewide base sales tax rate in Connecticut is 6.35% in 2026. Cities and counties can add their own local tax on top of the base rate — enter any local add-on below to see the full tax and total price.
Sales Tax Calculator 2026
Estimate the sales tax and total price using each state’s base rate (2026), plus any local add-on.
State base rates are the 2026 state-level rates (local add-ons excluded). Actual combined rates vary widely by city and county — many localities add 1–5%. Five states have no statewide sales tax (Alaska, Delaware, Montana, New Hampshire, Oregon), though some localities still levy local taxes.
Mortgage calculator for Connecticut homes
The average effective property tax rate in Connecticut is about 1.81% of a home’s value per year. When you use the mortgage calculator below, enter roughly that percentage of the home price in the yearly property tax field for a realistic Connecticut monthly payment.
Mortgage Payment Calculator
Work out your monthly principal & interest payment, total interest and the true total cost of your loan.
How it works: your loan amount (price minus down payment) is repaid in equal monthly instalments using the standard amortisation formula, so early payments are mostly interest and later ones mostly principal. Property tax and insurance, if entered, are simply spread evenly across each month. Your actual rate and payment will depend on your lender, credit profile and the deal you choose.
$5,430 a year. That’s the property tax on a $300,000 home in Connecticut — nearly five times the same bill in Alabama. Connecticut doesn’t hide where it gets its money. It taxes high earners through seven income brackets with an exemption that vanishes as you earn more, and then it taxes homeowners harder than almost anywhere else in America.
Income tax in Connecticut in 2026
Seven progressive brackets for a single filer:
- 2% on taxable income from $0 to $10,000
- 4.5% on taxable income from $10,000 to $50,000
- 5.5% on taxable income from $50,000 to $100,000
- 6% on taxable income from $100,000 to $200,000
- 6.5% on taxable income from $200,000 to $250,000
- 6.9% on taxable income from $250,000 to $500,000
- 6.99% on taxable income over $500,000
Now the unusual part. Connecticut has no standard deduction. None. In its place sits a $15,000 personal exemption — which sounds generous until you read the fine print. The exemption phases out $1 for every $1 of Connecticut AGI over $30,000. By $45,000 of income, it’s completely gone.
So a lower earner gets a real break, and someone on $75,000 gets nothing. No deduction, no exemption, tax on the full salary from dollar one. It’s the opposite of Colorado’s approach, where the federal standard deduction quietly shelters the first $16,100 for everyone. Connecticut’s system is deliberately built to shift the load up the income scale — and at $75,000, you’re already on the scale.
Worked example: $75,000 salary, single filer
Step 1: State taxable income. The personal exemption has fully phased out at this salary, and there’s no standard deduction, so Connecticut taxes the entire $75,000.
Step 2: Run the brackets. 2% on the first $10,000 is $200. 4.5% on the next $40,000 is $1,800. And 5.5% on the remaining $25,000 is $1,375. Total Connecticut income tax: $3,375.00, an effective rate of 4.5% of gross pay.
Step 3: Federal income tax, after the federal standard deduction of $16,100, is $7,670.00.
Step 4: FICA totals $5,737.50 — Social Security $4,650.00 and Medicare $1,087.50.
Step 5: $75,000 minus $3,375.00, $7,670.00 and $5,737.50 leaves take-home pay of $58,217.50 a year, about $2,239.13 every two weeks. That’s the lowest take-home of the states in this series at this salary — the missing exemption is exactly why.
Sales tax in Connecticut
Connecticut’s sales tax is 6.35%, charged at one statewide rate. A $1,000 purchase costs $63.50 in tax.
No local add-ons, no patchwork of district rates like California or Colorado. What you see is what you pay, anywhere in the state. It’s a middling rate nationally — not cheap, not punishing — and in Connecticut’s tax mix it’s almost the gentle part.
Property tax in Connecticut
This is where Connecticut really collects. The average effective property tax rate is 1.81%, a statewide average and the 3rd highest in the US.
On a $300,000 home, that’s about $5,430 a year — every year, for as long as you own it. Towns set their own mill rates and Connecticut towns lean heavily on property tax to fund schools and services, so bills in some communities run higher still. Comparing a Connecticut mortgage with an identical one in Arizona (0.48%) without checking the property tax line is how buyers get blindsided.
Frequently asked questions
Why don’t I get the $15,000 personal exemption?
Because it phases out. The exemption shrinks $1 for every $1 of Connecticut AGI above $30,000 and disappears entirely at $45,000. If you earn $75,000, you’re well past the cut-off — Connecticut taxes your full income, with no standard deduction to fall back on either.
What is tax benefit recapture?
It’s a rule that claws back the benefit of Connecticut’s lower brackets from very high earners, so they effectively pay near-top rates on all their income. The calculator on this page models the exemption phase-out but not recapture, so treat results at very high incomes as an approximation.
Why is Connecticut property tax so high?
Towns fund themselves — especially schools — largely through property tax, and the statewide average effective rate of 1.81% ranks 3rd highest in the country. On a $300,000 home, budget around $5,430 a year.
Is the sales tax the same everywhere in Connecticut?
Yes, 6.35% statewide, with no local add-ons. One rate, every town.
How does Connecticut compare with neighboring states for a $75,000 earner?
Harshly, at least on paper. The vanished exemption means Connecticut taxes the full $75,000, producing a $3,375 state bill and a 4.5% effective rate — higher than the effective rate a Californian pays at the same salary, despite California’s famous top rate.
Connecticut rewards people who run the numbers first: check your take-home in the paycheck calculator above, sanity-check a purchase with the sales tax calculator, and weigh a home’s true cost in the mortgage calculator before you sign anything.
