Assessment
Connecticut assesses property at 70% of fair market value. Each municipality conducts a full revaluation every 5 years. Between revaluations, values are adjusted through a physical inspection revaluation program.
Understanding this topic fully means looking at both the big picture and the specific details that apply to your situation. Every property is different, and the strategies that save the most money are the ones tailored to your particular home, location, and circumstances.
Start by gathering the basic facts about your property: its assessed value, the tax rate in your jurisdiction, and any exemptions currently applied. Then compare your situation to what is available. You may find opportunities for savings that you did not know existed.
Mill Rates
Connecticut mill rates vary dramatically by municipality. Wealthy communities with large grand lists (total assessed value) tend to have lower mill rates. Urban areas with lower property values and higher service needs tend to have higher rates. The statewide range typically spans from about 11 mills to 45+ mills.

Exemptions
| Program | Benefit | Who Qualifies |
|---|---|---|
| Elderly/Disabled Homeowner | $150-$1,250 tax credit (state-funded) | 65+ or totally disabled, income limits apply |
| Local Option Senior Freeze | Varies by municipality | 65+, adopted by some towns |
| Veterans | $1,500 off assessed value (basic) | Veterans with qualifying service |
| Disabled Veterans | $3,000+ off assessed value | Veterans with disability rating |
| Blind | $3,000 off assessed value | Legally blind |
Do not assume you are automatically enrolled. Most exemptions require an application, and many homeowners lose years of savings simply because they never filed. Contact your county assessor's office or check their website for the application form. Bring proof of eligibility (age verification, disability documentation, veteran status, etc.) and file well before the deadline.

The appeal process is designed to be accessible to regular homeowners, not just attorneys and tax professionals. You do not need to hire anyone to file. The key is preparation. Gather your evidence before the hearing, organize it clearly, and practice presenting your case in under 10 minutes. Lead with comparable sales, then cover any property record errors, and finish with photos or documentation of condition issues.
Keep your tone professional and factual. Review boards respond to evidence, not complaints. If you walk in with 3 strong comparable sales and a calm, organized presentation, you are already ahead of most appellants.
Your Next Steps
Here is exactly what to do this week to start lowering your Connecticut property taxes:
- Pull your property record card. Contact your county assessor's office or check their website. Compare every detail to your actual property. Flag anything that looks wrong.
- Check recent sales in your neighborhood. Look up 3 to 5 homes similar to yours that sold in the past 12 months. If they sold for less than your assessed value, you have a case.
- File for any exemptions you have not claimed. If you are a senior, veteran, or disabled homeowner in Connecticut, there may be exemptions saving you hundreds or thousands per year that you have not applied for yet.
- Mark your appeal deadline. Find the date on your most recent assessment notice and set a reminder for two weeks before. Do not let the deadline pass without acting.
Why Acting Now Matters in Connecticut
Every month you delay is money lost. Property taxes are assessed annually, and once the tax year begins, you are locked in at your current assessed value unless you file an appeal. There is no retroactive correction for years when you overpaid but did not challenge the assessment.
In Connecticut, the appeal window is limited. Once it closes, you wait a full year for your next opportunity. Homeowners who act promptly after receiving their assessment notice have the best outcomes because they have the most time to gather evidence, review comparable sales, and prepare a clear case.
If you are reading this and your current assessment notice is sitting unopened, go read it now. That single step puts you ahead of the majority of homeowners who never check their assessments at all.
