Comparing Connecticut taxes versus New York taxes doesn’t produce a single winner. New York generally costs more if you earn a high income, live in New York City, or buy an expensive home there. Connecticut generally costs more if you own multiple cars, sell a mid-range home, or plan to make large lifetime gifts. The rest turns on where you actually work and where you actually sleep.
Income Tax: The Headline Rates
Connecticut’s income tax runs from 2% at the bottom to 6.99% at the top, with the highest rate kicking in above $500,000 for single filers and $1,000,000 for joint filers.1Connecticut General Assembly Office of Legislative Research. Connecticut Income Tax Rates and Brackets Since 1991 No Connecticut town adds its own income tax.
New York’s state rates run from 4% to 10.9%, with the top rate applying to taxable income above $25,000,000 for single filers. Rates of 9.65% and 10.3% hit at lower thresholds well within reach of professional households. New York City residents pay an additional city income tax of up to 3.876% on top of the state tax.2Office of the New York City Comptroller. The NYC Personal Income Tax Before and After the Pandemic
A high earner in Manhattan can face a combined state and city rate above 14.7% on ordinary income and long-term capital gains, since both states tax investment gains as ordinary income. Connecticut’s top 6.99% is roughly half that. For anyone north of about $500,000 in income, this alone can swing the annual tax bill by tens of thousands of dollars.
One Connecticut wrinkle worth knowing: the state uses a benefit recapture that phases out the value of the lower brackets for high earners, so once your income crosses certain thresholds you’re effectively paying 6.99% on all your taxable income, not just the amount above $500,000.3Connecticut General Assembly Office of Legislative Research. OLR Backgrounder – A Guide to Connecticut’s Personal Income Tax Connecticut’s property tax credit against the income tax tops out at $200 and phases out entirely for higher earners.4Connecticut General Assembly Office of Legislative Research. Connecticut’s Property Tax Credit Against the State Income Tax
Who Owes What When You Live in One State and Work in the Other
Your home state taxes all your income no matter where you earned it. The state where you work taxes the wages sourced to that state. A resident credit stops the double taxation: your home state gives you credit for taxes paid to the work state on the same dollars. In practice, you end up paying the higher of the two rates.
A Connecticut resident commuting to a Manhattan office pays New York on the portion of wages earned during days physically present in New York, then claims that as a credit against Connecticut tax. If New York’s combined rate is 12% and Connecticut’s is 6.99%, you effectively pay 12% and Connecticut adds nothing on those wages. Both revenue departments audit workday tracking closely.
The Remote Work Trap for Connecticut Residents
The credit doesn’t always save you, and the reason is New York’s “convenience of the employer” rule. If you work for a New York employer but telecommute from Connecticut, New York still treats those remote days as New York workdays unless the remote arrangement is required by the employer, not just convenient for you.
The bar for “necessity” is deliberately hard to clear. New York’s guidance looks for things like employer reimbursement for a home office (including fair rental value), the home office address on business letterhead and cards, and public advertising that lists it as a place of business. Auditors rejected pandemic-era remote work as a necessity, and the rule was reaffirmed in 2024 litigation.5National Conference of State Legislatures. State and Local Tax Considerations of Remote Work Arrangements
The result: New York taxes income you earned while sitting in your Connecticut home office. Connecticut grants a credit, but only up to what Connecticut itself would have charged. If New York’s rate is higher, you eat the difference. Employees who never set foot in a New York office generally shouldn’t be caught by the rule, but making sure your employment agreement reflects a non-New York work location and no obligation to report to a New York office is the single most important defensive step.
Connecticut has its own version of the convenience rule, but it only reaches residents of other convenience-rule states, so it’s a much narrower problem.
Property Taxes
For most homeowners, property tax is the biggest annual tax expense in either state. Both rank among the country’s highest.
Connecticut assesses real property at 70% of fair market value and reassesses at least every five years.6Connecticut General Assembly. Getting Up to Speed on Property Revaluation The local mill rate is applied to that assessed value. Effective rates typically run between 1.75% and 2.5% of market value. Fairfield County towns often have lower mill rates but pricier homes, so the dollar bills stay large. Hartford and New Haven pair high mill rates with modest home values.
New York technically requires uniform-percentage assessment, but localities assess at varying fractions of market value and the state uses equalization rates to sort it out. In the suburbs that matter most to comparison shoppers, effective rates are higher than Connecticut’s: Westchester, Nassau, and parts of Suffolk regularly land between 2.5% and 3.5%. A $1 million home in a high-tax Westchester school district can generate $30,000 to $35,000 a year, compared to $18,000 to $25,000 for a comparable Connecticut home.
The Car Tax
Connecticut taxes cars and trucks as personal property, assessed at 70% of value under a depreciation schedule tied to MSRP. A new $50,000 vehicle would be assessed at roughly $29,750 in year one, declining over 20 years to a $500 floor.7Connecticut General Assembly. Personal Motor Vehicle Property Tax Assessments and Rates New York municipalities generally don’t impose an annual property tax on vehicles. For a household with multiple newer cars, that gap alone can run several hundred dollars a year in New York’s favor.
Sales Tax
Connecticut has a flat 6.35% statewide sales tax with no local add-ons, so the rate is the same in every town.8Connecticut State Department of Revenue Services. Sales and Use Tax Information A higher 7.75% rate applies to certain luxury items, including clothing, footwear, and handbags priced above $1,000 and most motor vehicles above $50,000.
New York’s state rate is just 4%, but counties and cities layer on local taxes. New York City’s combined rate is 8.875%.9Department of Taxation and Finance. Find Sales Tax Rates Most other densely populated areas land between 7% and 8.75%. Connecticut’s 6.35% looks high on paper but ends up cheaper than most of New York in day-to-day shopping.
Clothing is one clear New York advantage. Items priced under $110 are exempt from the state’s 4% sales tax, and New York City extends the exemption to its local portion as well.10Department of Taxation and Finance. Clothing and Footwear Exemption – Tax Bulletin ST-122 Connecticut repealed its year-round clothing exemption in 2011.11Connecticut State Department of Revenue Services. SN 2003(3), Sales and Use Taxes on Retail Sales of Clothing The state now offers a single annual Sales Tax Free Week during which clothing and footwear under $100 per item is temporarily exempt. Both states exempt most groceries and prescription medications.
Real Estate Transfer Taxes
Buying or selling in either state carries a one-time hit that can run into tens of thousands of dollars.
Connecticut charges a conveyance tax paid by the seller: 0.75% on the first $800,000 of the sale price, 1.25% on the portion between $800,000 and $2.5 million, and 2.25% on any amount above $2.5 million.12Connecticut General Assembly. Real Estate Conveyance Tax Municipalities add roughly 0.25% to 0.50%, bringing the total to about 1% to 2.75% of the sale price. A $2 million Connecticut home sale runs roughly $17,500 to $19,000 in combined state and local conveyance taxes.
New York’s base transfer tax is $2 per $500 of consideration (effectively 0.4%), also paid by the seller.13Department of Taxation and Finance. Real Estate Transfer Tax The state mansion tax adds 1% to any residential purchase of $1 million or more, paid by the buyer. In New York City, additional transfer taxes apply above $2 million (commercial) or $3 million (residential), and a supplemental graduated mansion tax ranging from 0.25% to 2.9% applies to residential purchases of $2 million or more. A $5 million New York City apartment purchase can trigger well over $200,000 in combined transfer taxes between buyer and seller.
So Connecticut’s conveyance tax hits sellers harder on mid-range homes. New York City’s layered mansion taxes punish buyers of expensive properties far more. Outside New York City, New York’s base transfer tax is actually one of the lowest costs in the transaction.
Estate and Gift Taxes
Both states impose an estate tax, neither has an inheritance tax, and this is where wealthy households often see the biggest planning difference.
New York’s 2026 estate tax exemption is $7,350,000.14Department of Taxation and Finance. Estate Tax Rates are graduated up to 16%. The trap is the cliff: if your taxable estate exceeds 105% of the exemption (roughly $7,717,500 for 2026), the entire exemption disappears and the full estate is subject to tax. A $7.3 million estate owes nothing. A $7.8 million estate can owe roughly $650,000 or more. Taxable gifts made within three years of death get pulled back into the estate, which can push a borderline estate over the cliff.
Connecticut ties its estate tax exemption to the federal amount. For 2025 that was $13.99 million,15CT.gov. Estate and Gift Tax Information and the 2026 federal exemption rose to a $15 million baseline under new legislation, so Connecticut’s threshold rises accordingly. Connecticut imposes a flat 12% on the amount above the exemption.16Connecticut General Assembly Office of Legislative Research. Estate, Inheritance, and Gift Taxes in CT and Other States There’s no cliff, so a dollar over the threshold triggers a modest bill rather than an avalanche.
Connecticut is one of the few states with a separate gift tax on lifetime transfers, using the same exemption amount as the estate tax.17CT.gov. Connecticut Estate and Gift Tax – General Instructions 2024 New York has no state gift tax, which gives New York residents more room to shrink their taxable estate through lifetime giving. Given New York’s cliff, that flexibility can be the difference between owing nothing and owing several hundred thousand dollars.
Which State Costs You More
A high-income earner in New York City almost always pays more, because state and city income tax stack and top out well above Connecticut’s rate. A Connecticut commuter to a New York office generally pays the New York rate anyway through the credit mechanism, but avoids the New York City surtax by living outside the city.
A remote worker for a New York employer living in Connecticut is the profile most likely to lose money to the convenience of the employer rule, because New York keeps taxing wages Connecticut can’t fully credit back.
A suburban homeowner often pays more in New York than in Connecticut, particularly in Westchester and Nassau, though Connecticut’s car tax narrows the gap for multi-vehicle households.
A shopper generally pays less in Connecticut outside New York City limits and less in New York City on clothing under $110.
A seller of a mid-range home pays more in Connecticut. A buyer of an expensive New York City home pays dramatically more there.
A wealthy family planning wealth transfers faces the sharpest tradeoff: New York’s cliff is punishing, but its lack of a state gift tax gives you tools to plan around it, while Connecticut is more forgiving at death but limits lifetime giving with its own gift tax.
