Board of Assessment Appeals: February 20 or March 20 (depending on municipality's Grand List completion)
Superior Court appeal: Within 2 months of BAA decision mailing date

⚠️ Missing the deadline means waiting another year and paying higher taxes. Mark your calendar now!
Step-by-Step Connecticut Appeal Process
Review Your Assessment Notice
Your assessment notice shows your property's taxable value. Look for the "assessed value" or "market value" – this is what you're appealing. Compare it to recent sales of similar homes in your neighborhood.
Gather Compelling Evidence
The - First level: Board of Assessment Appeals wants to see hard data, not opinions. Focus on:
- •Comparable sales: 3-5 similar properties that sold for less than your assessed value
- •Property condition: Photos and repair estimates documenting any issues
- •Assessment errors: Wrong square footage, features, or lot size
- •Market analysis: Evidence of declining values in your area
File Your Appeal Application
Submit your appeal to the - First level: Board of Assessment Appeals before the deadline. Most Connecticut counties now offer online filing, but some still require paper forms. Include all your evidence with the initial filing when possible.
Prepare Your Presentation
If your appeal goes to a hearing, you'll typically have 5-15 minutes to present. Organize your evidence clearly, practice your key points, and prepare to answer questions about your property value.
Attend Your Hearing
Present your evidence professionally and stick to facts about market value. The board members are usually reasonable people – they just need solid evidence to justify a reduction.
What Makes Connecticut's Appeal Process Unique
Connecticut stands virtually alone among states in lacking meaningful property tax limitations, making successful appeals crucial for taxpayers facing steep increases. The state's reliance on property taxes (with no county government layer) creates wide disparities - wealthy towns like Greenwich have low mill rates while struggling cities like Hartford have rates 3-4 times higher on similar property values.
The "crumbling foundation" crisis affecting thousands of homes in northeastern Connecticut created unique assessment challenges. Properties with defective concrete (containing pyrrhotite) can receive permanent assessment reductions until repaired, and the IRS allows casualty loss deductions. This regional disaster shaped Connecticut's approach to catastrophic property damage assessments. Additionally, Connecticut's two-tiered appeal deadline system (February 20 vs. March 20) based on Grand List timing creates confusion, as neighboring towns may have different deadlines despite being in the same region.
Assessment Cap/Protection
Connecticut lacks traditional property tax caps found in 45 other states. Limited protections include:
- Phase-in option: Municipalities may spread revaluation increases over 5 years
- Crumbling foundation relief: Special reassessment for homes with defective concrete (no 5-year limit)
- No general assessment increase limitation
- No homestead exemption beyond basic $1,000 for veterans
Required Filing Form
No standardized state form. Each municipality provides its own BAA application. Contact local tax assessor for proper form and filing requirements.

Start Your Connecticut AppealWhat Makes a Winning Appeal in Connecticut
The - First level: Board of Assessment Appeals is looking for objective evidence that your property is overvalued. The strongest cases combine multiple types of evidence:
✓ Strong Evidence
- • Recent comparable sales (within 6-12 months)
- • Professional appraisals
- • Clear documentation of errors
- • Photos of property condition issues
- • Contractor repair estimates
✗ Weak Arguments
- • "My taxes are too high"
- • Old or distant comparable sales
- • Zillow estimates alone
- • General market opinions
- • Emotional appeals
Common Connecticut Appeal Mistakes to Avoid
❌ Missing the deadline
Connecticut has strict filing deadlines with no extensions. Set multiple reminders!
❌ Using weak comparables
Properties must be truly similar – same neighborhood, size, age, and condition
❌ Being unprepared
Board members ask questions. Know your evidence inside and out
❌ Getting emotional
Stay professional and factual. The board responds to data, not frustration
❌ Giving up after denial
Many successful appeals happen at the state level after local denial
💰 The Cost of Waiting
Every year you don't appeal is money left on the table. The average Connecticut homeowner who successfully appeals saves $400-$1,200 per year. Over 10 years, that's $4,000-$12,000!

Connecticut Tax-Saving Strategies Beyond the Appeal
A successful appeal is just one way to lower your Connecticut property taxes. These additional strategies can stack with your appeal for maximum savings.
Strategy 1: Appeal During Your Revaluation Year
Connecticut mandates revaluation every 5 years. This is when the biggest assessment changes happen. If your town is in a reval year, review your new value immediately. The February 20 deadline is one of the earliest in the country -- don't miss it.
Strategy 2: Claim the State Income Tax Property Tax Credit
Connecticut offers a property tax credit of up to $300 on your state income tax return. Income limits apply. This isn't well-known and many qualifying homeowners miss it. Claim it on your CT-1040.
Strategy 3: Apply for Senior/Disabled Tax Relief
Connecticut has multiple senior programs that vary by municipality:
- Local option freeze: Assessment freezes for 65+ (income limits set by town)
- State circuit breaker: $250-$1,250 credit based on income for 65+ and disabled
- Local tax deferrals: Some towns allow seniors to defer as a lien
Strategy 4: Compare Mill Rates Across Town Lines
Connecticut has extreme mill rate variation -- from under 10 mills in Greenwich to over 40 in Hartford. If your property is near a town boundary, compare your assessment to similar homes in the neighboring town. A home assessed at the same value can have a 4x different tax bill depending on which town it's in. This doesn't help your appeal directly, but knowing the landscape helps you understand if you're relatively overpaying.
Strategy 5: Verify the 70% Ratio
Connecticut assesses at 70% of fair market value. Your assessment notice should show both the appraised value and the 70% assessed value. Challenge the appraised value if it exceeds what comparable properties have sold for. A $10,000 reduction in appraised value saves $7,000 in assessed value.
Strategy 6: Request Your Property Record Card
Connecticut assessors maintain detailed property record cards. Request yours and verify every field: square footage, number of rooms, condition grade, quality grade, year built, and improvements. Errors are common, especially in towns that haven't done a recent physical inspection.
Strategy 7: Apply for the Veteran Exemption
Connecticut veterans with an honorable discharge receive a $1,500 property tax exemption. Disabled veterans receive additional exemptions based on disability rating. Surviving spouses of veterans may also qualify. Apply through your town assessor.
2026 Connecticut Law Changes Affecting Your Appeal
Recent legislative changes in Connecticut may affect your property tax bill and appeal strategy.
70% Assessment Ratio and 5-Year Revaluation
Connecticut assesses property at 70% of fair market value. Municipalities must conduct a full revaluation every 5 years (with an interim adjustment at 2.5 years in some towns). Revaluation years often bring the largest assessment changes -- if your town is in a reval year, pay extra attention to your new value. The 70% ratio is applied to the appraised value. A $300,000 home has an assessed value of $210,000. Verify both the appraised value and the ratio application on your assessment notice.
Property Tax Credit (State Income Tax)
Connecticut offers a property tax credit on your state income tax return -- up to $300 for qualifying taxpayers. This isn't a property tax exemption but a state income tax credit based on property taxes paid. Income limits apply. Claim it on your CT-1040.
Senior and Disabled Tax Relief
Connecticut has multiple senior programs:
- Local option freeze: Municipalities can offer assessment freezes for seniors 65+ (income limits vary by town, typically $40,000-$60,000)
- State circuit breaker: Income-based property tax credit for seniors 65+ and disabled, worth $250-$1,250 depending on income and marital status
- Local tax deferrals: Some towns allow seniors to defer taxes as a lien
Mill Rate Variation
Connecticut has extreme variation in mill rates across municipalities. Rates range from under 10 mills in wealthy towns like Greenwich to over 40 mills in cities like Hartford and Bridgeport. This means the same home could have a tax bill 4x higher depending on which side of a town line it sits on. If you're near a municipal boundary, compare your assessment to comparable properties in the neighboring town.
