Fairfield County Property Tax Appeal, Connecticut

Travis Bunn·Updated July 24, 2026

Fairfield County is Connecticut's most populous county with 957,419 residents located in the southwestern corner of the state along Long Island Sound. The county includes four of Connecticut's seven largest cities, Bridgeport, Stamford, Norwalk, and Danbury, and is known for its affluent communities, proximity to New York City, and high property values. Connecticut abolished county governments in 1960, so property assessments are handled at the municipal level by each town's assessor. Property tax appeals matter significantly here because Fairfield County has the highest median property tax in Connecticut at $6,221 annually, substantially above both state and national averages, with effective rates varying widely by municipality from under 1.5% in Greenwich to over 3.5% in some towns.

Notable cities: Bridgeport, Stamford, Norwalk, Danbury, Greenwich, Westport, Fairfield, New Canaan

How Fairfield County Assesses Property

70%of market value

Assessed by: Municipal Tax Assessor (each town has its own assessor; no county-level assessment office)

Assessment cycle: Revaluation required at least every 5 years; timing varies by municipality

Notices typically mailed: November-December (for 2025 revaluation affecting July 2026 tax bills)

In Connecticut, all property is assessed at 70% of its fair market value as mandated by state statute. This assessment ratio applies uniformly across all municipalities. For example, if your home's market value is $477,700 (Fairfield County's median), at Connecticut's 70% assessment ratio your assessed value would be $334,390. At the county's effective rate of 1.30%, this results in approximately $4,347 in annual property taxes, though actual bills vary significantly by municipality due to differing mill rates.

The Appeal Process

Appeals are heard by the Board of Assessment Appeals. Board of Assessment Appeals hearings are informal, non-judicial proceedings typically lasting 10-15 minutes where you present evidence to one or more board members under oath. The hearing is recorded, and board members may ask questions about your evidence. Decisions are made separately at deliberation meetings, not at the hearing itself, and you'll receive written notice of the outcome within approximately one week.

Step 1: Review your property assessment notice received in November-December 2025 showing your new market value and assessed value (at 70% ratio) for the October 1, 2025 Grand List

Step 2: Gather evidence supporting your claim that the assessed value is too high, including comparable sales from the same time period as the revaluation, recent appraisals, photographs documenting property condition, or proof of assessment errors in property characteristics

Step 3: Complete and file your written appeal application with your town's Board of Assessment Appeals by February 20, 2026 (or March 20 if extended), including your property information, estimated market value, and reason for appeal

Step 4: Request or attend an informal hearing with the assessor's office if your municipality offers this option, which may resolve issues without formal Board review, particularly for clerical errors or property data corrections

Step 5: Attend your formal hearing before the Board of Assessment Appeals in March or April 2026, where you'll have 10-15 minutes to present your evidence; hearings are recorded but informal and non-judicial

Step 6: Receive the Board's written decision within one week after deliberations; the Board may increase, decrease, or maintain your assessment

Step 7: If dissatisfied with the Board's decision, appeal to Connecticut Superior Court within two months of the date the Board mails its decision notice, under Connecticut General Statutes § 12-117a

Frequently Asked Questions

What is the deadline to appeal my property taxes in Fairfield County, Connecticut?

The deadline to file a property tax appeal with your municipal Board of Assessment Appeals is February 20, 2026, for most towns in Fairfield County. Some municipalities may extend this deadline to March 20, 2026. Connecticut statute requires appeals to be filed by these dates, and when February 20 falls on a weekend, the deadline typically moves to the preceding business day. You must file with your specific town's Board of Assessment Appeals since Connecticut has no county-level appeal process. Missing this deadline means you lose your right to appeal for that assessment year, so it's critical to file on time even if you're still gathering evidence.

How do I file a property tax appeal in Fairfield County online?

Online filing availability varies by municipality in Fairfield County since each town handles its own assessments and appeals. Some larger municipalities like Stamford and Fairfield offer online appeal submission portals through their assessor websites. However, most towns require you to download an appeal application form from the assessor's website, complete it, and submit it by mail or in-person to the Board of Assessment Appeals. Check your specific town assessor's website or call their office to confirm whether they accept electronic submissions. If online filing is not available, you can mail your completed appeal form to your town's Tax Assessor's office, but remember that postmarks are not accepted, the appeal must be received by the February 20 deadline.

What happens at a Board of Assessment Appeals hearing in Fairfield County?

Board of Assessment Appeals hearings in Fairfield County municipalities are informal, non-judicial proceedings where you present your case in 10-15 minutes. You'll be sworn in under oath and asked to explain why you believe your assessment is incorrect, using evidence such as comparable sales, appraisals, photographs, or documentation of property errors. One or more board members will hear your presentation, may ask questions, and will record the proceedings. Importantly, the Board does not make decisions during the hearing itself, they deliberate separately at a later meeting and will mail you their written decision within about one week. The Board has authority to increase, decrease, or maintain your assessment. You may represent yourself or hire a professional such as an attorney or appraiser to present your case.

How much can I save by appealing my property taxes in Fairfield County?

Potential savings from a successful appeal in Fairfield County depend on your property's assessed value and your municipality's mill rate. With the county's median annual tax bill of $6,221 and effective rate of 1.30%, even a modest 10% reduction in assessed value could save approximately $622 annually. However, savings vary dramatically across the county, towns like Greenwich with low mill rates see smaller dollar savings per assessment reduction, while higher-tax municipalities like Bridgeport or Stamford produce larger savings. Any assessment reduction you achieve typically applies not just to one year but until the next revaluation (usually 5 years), multiplying your total savings. For example, a $30,000 reduction in assessed value in a town with a 30 mill rate saves about $900 annually, or $4,500 over five years.

What evidence do I need for a successful property tax appeal in Fairfield County?

The strongest evidence for Fairfield County appeals includes comparable sales of similar properties that sold near your town's revaluation date (typically October 1, 2025 for the current appeal cycle), showing that similar homes sold for less than your assessed market value. A professional appraisal from a licensed appraiser dated close to the assessment date carries significant weight. Additionally, bring photographs documenting property defects, damage, or deferred maintenance that affect value, a copy of your property record card showing any errors in square footage or property characteristics, and repair estimates for significant issues. Board members particularly value comparable sales data from your immediate neighborhood with similar size, age, and condition properties. Remember that Connecticut assesses at 70% of market value, so your evidence should demonstrate that the market value used by the assessor was too high.

Can I appeal my Fairfield County property taxes if I missed the revaluation year?

Yes, Connecticut law allows property owners to file appeals annually, not just during revaluation years. While the first year after a municipality's revaluation offers the greatest savings potential because the assessment remains in effect until the next revaluation (typically 5 years), you can still appeal in subsequent years if circumstances change. However, appeals in non-revaluation years are more challenging because you must demonstrate that your property's value has declined relative to other properties in town or that errors exist in your assessment. Successful appeals in off-revaluation years often involve properties with new damage, significant market changes affecting specific property types, or discovered assessment errors. The same February 20 deadline applies regardless of whether it's a revaluation year, and you follow the identical Board of Assessment Appeals process.

What is Connecticut's 70% assessment ratio and how does it affect my Fairfield County property taxes?

Connecticut law requires all municipalities to assess property at exactly 70% of fair market value, as mandated by Connecticut General Statutes § 12-62. This means if your Fairfield County home has a market value of $500,000, your assessed value for tax calculation purposes will be $350,000 (70% of market value). Your actual tax bill is then calculated by multiplying this assessed value by your town's mill rate. For example, with an assessed value of $350,000 and a mill rate of 30, your annual tax would be $10,500. Understanding this ratio is critical for appeals because you need to prove the market value was wrong, not challenge the 70% assessment ratio itself, which is fixed statewide. When comparing your assessment to neighboring properties, remember that everyone's assessed value should be 70% of their actual market value.

What if I disagree with my Board of Assessment Appeals decision in Fairfield County?

If you're dissatisfied with your Board of Assessment Appeals decision, you have the right to appeal to Connecticut Superior Court, but you must act quickly. Connecticut General Statutes § 12-117a requires that you file your Superior Court appeal within two months of the date the Board mails its decision notice, this deadline is strictly enforced and missing it means losing your appeal rights for that tax year. The Superior Court hears property tax appeals de novo, meaning they review the case fresh without deference to the Board's decision. Superior Court appeals are more formal than Board hearings and typically require expert testimony from a licensed appraiser to prove your property's value. For commercial, industrial, or apartment properties assessed over $1 million, you must file an appraisal with the court within 120 days. Many property owners hire tax appeal attorneys for Superior Court proceedings given the complexity and procedural requirements.
