Hartford property tax for fiscal year 2026 is set at 68.95 mills on real estate and personal property and 32.46 mills on motor vehicles, applied to 70% of each property’s fair market value. Bills come in two installments due July 1 and January 1, and anything paid late accrues 18% annual interest from the original due date.
How Your Bill Is Calculated
Every taxable property in Hartford is assessed at 70% of its fair market value, the uniform ratio required by Connecticut law.1Connecticut General Statutes. Connecticut Code 12-62a – Uniform Assessment Date and Rate A home with a fair market value of $200,000 has an assessed value of $140,000. The city then applies the mill rate to that assessed value, where one mill equals one dollar of tax per $1,000 of assessed value.2City of Hartford. Office Of The Tax Collector
At the current real estate rate of 68.95 mills, that $140,000 assessment produces an annual bill of $9,653 ($140,000 ÷ 1,000 × 68.95). The real estate and personal property rate is 68.95 mills; motor vehicles are taxed separately at 32.46 mills.2City of Hartford. Office Of The Tax Collector
A citywide revaluation takes effect with the October 1, 2026 Grand List.3City of Hartford. Office of the Tax Assessor Connecticut requires municipalities to revalue property at least every five years, and the last Hartford revaluation was in 2021. Expect assessments to shift to reflect current market conditions. If values in your neighborhood have climbed since 2021, your assessed value will likely rise even if the mill rate falls.
What Hartford Taxes
Three categories of property are on the tax rolls. Real estate covers land and permanent structures of every kind, from single-family homes to apartment buildings, commercial properties, and vacant lots. Motor vehicles include cars, trucks, and trailers registered with the state as of October 1. Personal property covers tangible business assets such as equipment, furniture, fixtures, and machinery.3City of Hartford. Office of the Tax Assessor
Motor Vehicles
Your vehicle’s assessed value uses the same 70% ratio and is based on its market value as of the October 1 Grand List date. Buy or register a car after October 1, and it won’t show up on the regular bill. Hartford issues a supplemental motor vehicle bill for vehicles registered between October 2 and the following summer, prorated by the month you registered.4Connecticut General Statutes. Connecticut Code 12-71b – Taxation of Motor Vehicles Registered After Assessment Date Supplemental bills are due January 1, with a final payment deadline of February 1.
Business Personal Property
If you run a business in Hartford, you must file a personal property declaration with the Assessor’s Office in early November each year. The 2025 deadline was November 3. Miss it and the city adds a 25% penalty on top of your assessment and sets the valuation itself.5City of Hartford. Business Personal Property Declarations Taxable personal property includes office furniture, computers, tools, machinery, leasehold improvements, and unregistered vehicles like trailers or snowmobiles. Equipment stays taxable as long as it’s on your books, even after it has fully depreciated.
When Payment Is Due
Hartford splits most tax bills into two installments:6City of Hartford. Tax Information
- First installment: due July 1, with a final payment date of August 1.
- Second installment: due January 1, with a final payment date of February 1.
If your total bill is $100 or less, the full amount is due July 1.6City of Hartford. Tax Information When a final payment date lands on a weekend, the deadline shifts to the following Monday. The same dates apply to real estate, personal property, and motor vehicle bills.
Qualifying elderly taxpayers approved for the installment program pay four times a year instead of twice: July 1, October 1, January 1, and April 1, each with a one-month payment window.6City of Hartford. Tax Information
How to Pay
Hartford accepts payment three ways. The city’s online tax portal takes credit cards (Visa, Mastercard, Discover, Amex) and electronic checks. Credit cards carry a 2.99% convenience fee with a $3.95 minimum. Electronic checks cost a flat $0.50.7City of Hartford. City of Hartford – Tax Bills Search and Pay On a four-figure installment, the e-check option saves meaningful money.
Mailed payments go to City of Hartford, P.O. Box 412834, Boston, MA 02241-2834.2City of Hartford. Office Of The Tax Collector The postmark date counts as your payment date. You can also pay in person at City Hall during business hours.
If you have a mortgage, your lender may pay the city directly from an escrow account funded through your monthly mortgage payment. Confirm with your servicer before paying anything yourself, or you may create a double payment. Escrow accounts generally don’t cover supplemental motor vehicle bills, so plan to handle those on your own.
What Late Payment Costs
Connecticut law applies interest at 18% per year on any delinquent tax balance, running from the original due date until the balance is paid in full.8Connecticut General Statutes. Connecticut Code 12-146 – Delinquent Tax or Installment That’s 1.5% per month, and any partial month counts as a full month. The minimum interest charge is $2 per installment. The city has no authority to waive it.
Motor vehicle registrations add a second deadline. If you owe back taxes, the DMV won’t let you renew your registration. Credit card payments clear in two business days for motor vehicle purposes; check payments take ten business days.7City of Hartford. City of Hartford – Tax Bills Search and Pay If a registration deadline is close, pay by credit card.
What Happens If You Still Don’t Pay
Unpaid property taxes in Connecticut create an automatic lien on your real estate. Let the balance sit long enough and the tax collector can levy on the property and sell it at public auction. Before any sale, the collector must post notice publicly, file it with the Town Clerk’s land records, and send certified notice to the owner and to any mortgage holders or lienholders of record.9Connecticut General Statutes. Connecticut Code 12-157 – Method of Selling Real Estate for Taxes
You get a six-month redemption window after a tax sale. During that period you can reclaim the property by paying all delinquent taxes, interest, and charges, plus 18% annual interest on whatever the buyer paid at auction.9Connecticut General Statutes. Connecticut Code 12-157 – Method of Selling Real Estate for Taxes If no one bids, the municipality itself can take ownership.
Exemptions That Can Lower Your Bill
Hartford administers several programs that reduce or eliminate property tax for qualifying residents. All require an application, and most have firm annual deadlines.
Veterans
Connecticut exempts $1,000 in assessed value for veterans who served during wartime and received an honorable discharge.10Connecticut General Statutes. Connecticut General Statutes Title 12 Taxation 12-81 – Exemptions Veterans with a VA disability rating of 10% or more qualify for a larger exemption of up to $3,500 in assessed value. Those with a 100% permanent and total disability rating are fully exempt from property tax on their primary home and vehicle. File your DD-214 discharge papers with the Town Clerk before October 1 of the assessment year to claim any veteran exemption.11State of Connecticut Office of Policy and Management. Additional Veterans Tax Relief Program
Elderly and Disabled Residents
The Circuit Breaker program provides a property tax credit for homeowners who are 65 or older or totally disabled. The credit runs up to $1,250 for married couples and $1,000 for single applicants, calculated on a graduated income scale.12State of Connecticut Office of Policy and Management. Homeowners – Elderly/Disabled (Circuit Breaker) Tax Relief Program Income from all sources counts, including Social Security and tax-exempt interest. For the 2026 application period (based on 2025 income), the limits are $56,500 for married applicants and $46,300 for single applicants. Bring your federal tax return (if you filed one) and your SSA-1099 form to the Assessor’s Office. Approved elderly taxpayers also get the four-installment payment option.6City of Hartford.

Appealing an Assessment You Think Is Wrong
Your first stop is the Board of Assessment Appeals. Written appeals are due by February 20 of the year following the assessment date, or by March 20 if the assessor received a filing extension. The appeal must include your name, a description of the property, your estimate of its value, and the reason you’re challenging the assessment.13Connecticut General Statutes. Connecticut Code 12-111 – Appeals to Board of Assessment Appeals
Strong appeals carry evidence. Recent comparable sales in your neighborhood tend to be the most persuasive. A professional appraisal helps. So do photographs documenting condition issues the assessment missed, and records showing errors in the property file such as wrong square footage, wrong lot size, or features that aren’t actually there. The board will schedule a hearing and notify you at least seven days in advance.
If the board rules against you, you can appeal to Superior Court within two months of receiving the decision.14Connecticut Judicial Branch. Tax and Administrative Appeals Session FAQs Pay your taxes while any appeal is pending. Winning later produces a refund; skipping payment produces interest charges whether you win or lose. With the 2026 revaluation coming, pay close attention to the new assessed value on your notice. The February 20 deadline doesn’t move.
