Hartford Property Tax: Rates, Exemptions & Appeals (2026)

For residential real estate in Hartford County, you appeal to your town or city Board of Assessment Appeals (BAA), not to a county office. The standard Connecticut deadline is February 20 after the October 1 assessment date—so the next regular residential deadline is February 20, 2027 for the October 1, 2026 Grand List, unless your municipality grants an assessor extension, which moves the filing deadline to March 20.

File with the assessor/BAA in the municipality where the home sits. For example, City of Hartford appeals go to Hartford Board of Assessment Appeals, c/o Assessor’s Office, 550 Main Street, Room 108, Hartford, CT 06103, or assessment@hartford.gov; West Hartford accepts hand delivery, mail, fax, or email; East Hartford and New Britain publish their own town/city forms and return addresses.

How assessments work in Hartford County

Hartford County is not the property-tax assessing authority. Connecticut counties do not run assessors or tax collectors for homeowners; your municipality does. That means a home in Hartford, West Hartford, East Hartford, New Britain, Bristol, Farmington, Glastonbury, Enfield, etc. has its own assessor, Board of Assessment Appeals, mill rate, exemptions administration, and tax collector.

The statewide assessment date is October 1. Real estate is generally assessed at 70% of fair market value as of the last revaluation date. Between revaluations, the assessor usually carries the value forward, with updates for new construction, demolition, corrections, splits/combines, and other taxable changes.

Connecticut requires municipal revaluation every five years. Several large Hartford County municipalities are in a 2026 revaluation cycle. The City of Hartford says it implemented the October 1, 2021 revaluation and that the next revaluation is scheduled for October 1, 2026. West Hartford’s 2026 revaluation page says its last revaluation was 2021 and the town selected Vision Government Solutions and Municipal Valuation Services for the 2026 residential/commercial revaluation. East Hartford says its state-mandated 2026 revaluation is for the Grand List of October 1, 2026, with assessment notices expected in December 2026, informal hearings in December 2026–January 2027, BAA in March 2027, and tax bills due July 2027 and January 2028.

A mill rate is the tax per $1,000 of assessed value. OPM’s formula is: assessment × mill rate ÷ 1,000 = tax bill. The City of Hartford’s FY2026 tax page lists a 68.95 mill rate for real property and personal property and 32.46 for motor vehicles; the first semiannual installment on the October 1, 2025 Grand List was due July 1, 2026 and payable by August 3, 2026.

Whether you should appeal

Appeal if you can show the assessment is too high, not merely that the tax bill is painful. For residential property, start by dividing your assessment by 0.70. If Hartford assesses your home at $210,000, the implied market value is $300,000. Your question is: could your house realistically have sold for about $300,000 as of the relevant October 1 valuation date?

Good evidence includes: comparable sales before the valuation date, an appraisal tied to that date, photos of condition problems, incorrect property-card data, or proof that the assessor counted finished area, bathrooms, garages, outbuildings, or land incorrectly. In a revaluation year, use the revaluation company’s informal review first if your town offers it; East Hartford’s 2026 schedule specifically includes informal hearings before the March 2027 BAA.

Do not rely on Zillow alone, your mortgage appraisal from a different date, or taxes in another town. West Hartford warns that real estate assessments are as of the last revaluation date and that sales/appraisal information after that date will not be considered.

No official Hartford County-wide appeal success rate or median reduction is published by the state or county because appeals are municipal. I did not find an official Hartford, West Hartford, East Hartford, or New Britain page publishing a clean annual homeowner success-rate table, so do not assume a typical percentage reduction.

Worked example using Hartford’s actual FY2026 real-property mill rate: suppose a Hartford homeowner’s assessment is $245,000, implying a market value of $350,000. If comparable October 1-value-date sales support a market value of $325,000, the corrected assessment would be $227,500. Assessment reduction: $17,500. Annual tax reduction at 68.95 mills: $17,500 × 68.95 ÷ 1,000 = $1,206.63. Because Hartford bills in two installments, that is about $603 per installment. Your savings in another Hartford County town will be different because the mill rate is different.

Step-by-step how to file

1. Find your town’s current property card. Use your assessor’s online records or visit the assessor. Confirm living area, lot size, year built, condition, grade, finished basement, garages, porches, and outbuildings.

2. Check the correct valuation date. For Hartford, West Hartford, and East Hartford homes affected by 2026 revaluation, the key date is expected to be October 1, 2026. For towns not revaluing in 2026, the assessment normally traces back to that town’s last revaluation date, adjusted for later physical changes.

3. Use the official BAA form. Form names vary by municipality. City of Hartford’s PDF is titled “Hartford Board of Assessment Appeals — Application to Appeal” and cites C.G.S. §12-111. East Hartford’s form is “Petition to the Board of Assessment Appeals, Town of East Hartford, Connecticut, for the Grand List of October 1, 2025.” West Hartford lists a “Board of Assessment Appeals Application” and an “Agent Appointment Form.” New Britain’s appeals page says appeal forms are available in the Assessor’s Office.

4. Include the required information. Connecticut requires the property owner’s name, signer’s name/position, property description, mailing and email address for correspondence, reason for appeal, your estimate of value, owner/authorized-agent signature, and date. If an agent appears, attach written authorization.

5. File by the deadline your town publishes. The normal deadline is February 20. If an extension is granted under C.G.S. §12-117, the taxpayer appeal deadline becomes March 20 and hearings move to April. For the City of Hartford’s 2026 posted deadline, applications had to be filed on or before February 20, 2026; hearings were scheduled throughout March 2026.

6. Use an accepted delivery method. Hartford’s notice says applications may be submitted by mail, in person, or email to assessment@hartford.gov; the form also lists fax 860-722-6142. West Hartford accepts hand delivery, mail, fax, or email to whassessment@westhartfordct.gov, fax 860-561-7590, Assessment Office, Town Hall, 50 South Main Street, Room 142, West Hartford, CT 06107. East Hartford’s 2026 form directs completed forms to Board of Assessment Appeals, c/o Assessor’s Office, Town of East Hartford, 740 Main Street, East Hartford, CT 06108. New Britain directs returns to Assessor’s Office, 27 West Main Street, New Britain, CT 06051. I found no countywide appeal portal and no official filing fee for a municipal BAA residential appeal.

What happens after

For a regular March BAA cycle, the board must notify timely applicants of the hearing date, time, and place by March 1, hold hearings in March, and decide by the last business day of March. If the assessor-extension rule applies, notice is due by April 1 and hearings are in April.

A residential hearing is usually short. Bring three copies if your town does not specify otherwise: your property card, a one-page value calculation, comparable sales, photos, repair estimates, and any appraisal. Be ready to answer questions under oath. The BAA may reduce, leave unchanged, or increase an assessment, though increases in homeowner appeals are uncommon when the issue is simply your own value.

The board sends written notice of its decision, generally within one week after determination. If you still disagree, a further appeal is to Connecticut Superior Court, generally within two months of the BAA action/notice. That is a lawsuit, not another assessor meeting, so evaluate the dollars at stake before filing.

Local tips

Hartford: use the Assessor’s Office at 550 Main Street, Room 108. Hartford also has meaningful relief programs: for 2025 applications, the city page lists State elderly/disabled homeowner income limits of $46,300 single / $56,500 married and a Hartford local elderly credit with higher limits, plus veterans, disabled veterans, active-duty motor vehicle, blind, farm/forest/open space, and other exemptions.

West Hartford: 2026 is a revaluation year. Its BAA page is unusually clear that post-revaluation-date sales/appraisals will not be considered for real estate appeals, so focus on sales before the valuation date and property-data errors.

East Hartford: watch the 2026 revaluation mailings. The town’s schedule says assessment notices are mailed in December 2026, informal hearings occur December 2026–January 2027, and the BAA follows in March 2027.

New Britain: its appeals page says hearings are by appointment only and warns that postmarks are not accepted when the deadline rule applies. If you own there, use the assessor’s published process rather than a neighboring town’s form.

Finally, check exemptions before you appeal. Connecticut has no universal “homestead exemption” like some states, but Hartford County homeowners may qualify for elderly/disabled tax relief, veterans exemptions, blind/totally disabled exemptions, active-duty motor vehicle exemptions, or PA 490 farm/forest/open-space classification depending on the property and town rules.

Hartford County Property Tax Rate

No Hartford County-wide property-tax millage exists; Connecticut counties are geographic subdivisions only, and property-tax mill rates are municipal rather than countywide.

When Are Property Taxes Due in Hartford County?

No Hartford County-wide property-tax payment due dates exist; Connecticut law leaves installment choice and due-date designation to each municipality's legislative body. Municipalities may set property taxes as a single installment, two semiannual installments, or four quarterly installments, subject to Connecticut General Statutes Sec. 12-142.

This is not the same as the assessment appeal deadline above. The appeal deadline is your window to contest your assessed value; the payment due date is when the resulting tax bill must be paid. Missing one does not affect the other, but missing either has real consequences — one forfeits your right to appeal for the year, the other can trigger penalties and interest.
