Property taxes are one of the most important numbers to understand before buying in Stamford — and one of the most misunderstood. The mill rate sounds large, but it is applied to the assessed value (70% of market value), not the sale price. Here is what it actually means for your budget. For where Stamford home values themselves stand, see my Stamford market report.
How to calculate your Stamford property tax
- Look up the property's current assessed value in city records.
- Confirm its taxing district and the rate for the fiscal year.
- Multiply assessed value by mill rate ÷ 1,000. Account for applicable exemptions and additional district charges.
Connecticut assesses real property at 70% of the assessor's estimated market value as of the applicable revaluation date. Stamford's last revaluation was October 1, 2022. A purchase does not automatically reset the assessment to 70% of the sale price. Use the current assessed value in city records: a $455,000 assessment at District A's 25.14 mills produces $11,438.70 in annual base tax before exemptions or additional district charges.

Key things to know before you close
- Use the current parcel assessment and bill; do not substitute 70% of your offer price.
- Confirm payment dates and mortgage escrow arrangements with the city and your lender.
- Condos and houses in the same district use the same real-property rate, but their assessments and total bills differ.
- You can ask Stamford's Board of Assessment Appeals to review your assessment. Check the city's current application instructions and deadline, and use evidence appropriate to the applicable valuation date. A recent purchase price alone does not establish the correct assessment.
How Stamford compares to neighboring towns
Compare the actual assessed value, current district rate, exemptions, and any additional charges for each property. A lower mill rate alone does not guarantee a lower annual bill. Different towns' revaluation dates can also make rate-only comparisons misleading.

Are property taxes included in my mortgage payment in Connecticut?
Usually yes, if your lender requires an escrow account (common when you put less than 20% down). The lender collects 1/12 of your estimated annual property tax each month and pays the bill when it is due. If you put 20% or more down, some lenders allow you to waive escrow and pay the tax bill yourself, directly to the City of Stamford twice per year (July and January are the typical due dates). Confirm the escrow terms with your lender before closing.
Can I appeal my property tax assessment in Stamford?
You can ask Stamford's Board of Assessment Appeals to review your assessment. Check the city's current application instructions and deadline, and use evidence appropriate to the applicable valuation date. A recent purchase price alone does not establish the correct assessment.
