Connecticut Property Taxes & Your Mortgage
- ✔ Connecticut has the 3rd highest property taxes in the nation
- ✔ Mill rates range from 11 (Greenwich) to 69 (Hartford)
- ✔ Property taxes directly affect your monthly mortgage payment
- ✔ Location matters: similar homes can have vastly different tax bills
If you're buying a home in Connecticut property taxes are as important as the purchase price. With the third highest property taxes in the country behind only New Jersey and Illinois, Connecticut's taxes can add hundreds or even thousands of dollars to your monthly housing costs. This guide explains how Connecticut property taxes work, how they affect your mortgage approval and monthly payment and which areas have the highest and lowest tax rates.
How Connecticut Property Taxes Work
Connecticut's property tax system is unique in several ways that directly impact homebuyers:
Municipal Control
Unlike states where counties handle property taxes, each of Connecticut's 169 municipalities sets its own tax rate. This creates variation: a home in Greenwich faces completely different taxes than an identical home in Hartford even if both have the same market value.
Assessment Ratio
Connecticut law requires properties to be assessed at 70% of fair market value. This assessment ratio is consistent statewide though the frequency of revaluations varies by town (state law requires revaluation at least every five years).
Mill Rates
Each municipality sets an annual mill rate, the amount of tax per $1,000 of assessed value. One mill equals $1 of tax for every $1,000 of assessed value.
The formula:
Market Value × 0.70 (assessment ratio) ÷ 1,000 × Mill Rate = Annual Property Tax
Example Calculation
| Step | Calculation | Result |
|---|---|---|
| Home market value | — | $500,000 |
| Assessed value (70%) | $500,000 × 0.70 | $350,000 |
| Divide by 1,000 | $350,000 ÷ 1,000 | 350 |
| Apply mill rate (example: 30 mills) | 350 × 30 | $10,500/year |
| Monthly property tax | $10,500 ÷ 12 | $875/month |
Connecticut Mill Rates
Connecticut mill rates for fiscal year 2025-26 range from about 11 mills to nearly 69 mills. This creates dramatic differences in property tax bills across the state.
Towns with the Lowest Mill Rates
| Town | Mill Rate (FY 2025-26) | Annual Tax on $500K Home | Monthly Tax |
|---|---|---|---|
| Washington | 10.85 | $3,798 | $316 |
| Salisbury | 11.00 | $3,850 | $321 |
| Sharon | 11.15 | $3,903 | $325 |
| Greenwich | 12.04 | $4,214 | $351 |
| Darien | 16.86 | $5,901 | $492 |
| Westport | 17.48 | $6,118 | $510 |
| New Canaan | 17.79 | $6,227 | $519 |
| Wilton | 19.24 | $6,734 | $561 |

Note: Low mill rates often correlate with high home values. Towns like Greenwich have low mill rates because the tax base (total assessed property value) is so large that a smaller percentage still generates substantial revenue.
Towns with the Highest Mill Rates
| Town | Mill Rate (FY 2025-26) | Annual Tax on $500K Home | Monthly Tax |
|---|---|---|---|
| Hartford | 68.95 | $24,133 | $2,011 |
| Waterbury | 60.21 | $21,074 | $1,756 |
| New Britain | 49.50 | $17,325 | $1,444 |
| Bridgeport | 43.45 | $15,208 | $1,267 |
| New Haven | 43.88 | $15,358 | $1,280 |
| Hamden | 47.13 | $16,496 | $1,375 |
| East Hartford | 44.56 | $15,596 | $1,300 |
| Meriden | 36.92 | $12,922 | $1,077 |

Note: Cities with higher mill rates often have lower median home values, commercial/industrial tax base challenges, and higher service demands.
The Difference Mill Rates Make
For a home with a $500,000 market value:
| Town | Annual Property Tax | Monthly Tax | Difference from Greenwich |
|---|---|---|---|
| Greenwich (12.04 mills) | $4,214 | $351 | — |
| Stamford (25.48 mills) | $8,918 | $743 | +$392/month |
| New Haven (43.88 mills) | $15,358 | $1,280 | +$929/month |
| Hartford (68.95 mills) | $24,133 | $2,011 | +$1,660/month |
The takeaway: A $500,000 home in Hartford costs $1,660 more per month in property taxes alone than the same priced home in Greenwich. Over a 30 year mortgage that's nearly $600,000 in additional property tax payments.
How Property Taxes Affect Your Mortgage
Property taxes directly impact your mortgage approval, monthly payment and how much house you can afford.
Understanding PITI
Your mortgage payment is broken down as PITI:
- Principal – paying down your loan balance
- Interest – the cost of borrowing
- Taxes – property taxes
- Insurance – homeowners insurance
Most lenders require you to escrow property taxes, meaning they collect 1/12 of your annual tax bill each month and pay it on your behalf. This means your monthly mortgage payment includes your property taxes.
Impact on Debt-to-Income Ratio
When lenders calculate your debt-to-income (DTI) ratio to determine how much you can borrow they include the full PITI payment and not just principal and interest.
Lenders typically want:
- Front-end DTI: Housing payment (PITI) below 28-31% of gross monthly income
- Back-end DTI: Total debt payments below 43-45% of gross monthly income
In high tax Connecticut towns property taxes can consume a significant portion of your allowable DTI reducing how much you can borrow for the home itself.
How Property Taxes Reduce Buying Power
Let's compare two buyers with identical income and down payments purchasing in different Connecticut towns:
| Factor | Buyer A: Greenwich | Buyer B: Hartford |
|---|---|---|
| Gross monthly income | $15,000 | $15,000 |
| Max housing payment (28%) | $4,200 | $4,200 |
| Homeowners insurance (est.) | $200/month | $200/month |
| Property tax on $600K home | $421/month | $2,413/month |
| Remaining for P&I | $3,579/month | $1,587/month |
| Approximate loan amount supported (at 6.5%) | $565,000 | $250,000 |
Note: Example calculations assume 70% assessment ratio and current mill rates. Actual loan qualification depends on credit score, down payment, other debts and lender guidelines.
The same income supports a loan more than twice as large in Greenwich compared to Hartford entirely because of property taxes.
Property Tax Strategies for Connecticut Homebuyers
Compare Total Monthly Cost, Not Just Price
When evaluating homes in different towns calculate the full monthly PITI payment for each property. A $450,000 home in a high tax town may cost more monthly than a $550,000 home in a low tax town.
Quick comparison tool:
- Home price × 0.70 ÷ 1,000 × mill rate = annual property tax
- Divide by 12 for monthly tax
- Add to estimated principal, interest and insurance for true monthly cost
Understand Revaluation Timing
Connecticut towns must revalue properties at least every five years. If you buy shortly before a revaluation in a rapidly appreciating market your assessed value and taxes may increase significantly.
Ask your real estate agent when the town last completed a revaluation and when the next one is scheduled.
Research Tax Abatements and Exemptions
Connecticut offers several property tax relief programs:
- Elderly/Disabled Tax Relief: Homeowners 65+ or totally disabled may qualify for tax credits
- Veterans Exemption: Eligible veterans receive a $1,500 assessment exemption (higher for disabled veterans)
- Property Tax Credit: State income tax credit up to $300 for qualifying homeowners
- Circuit Breaker: Additional relief for seniors with limited income
Connecticut Property Taxes by Region
Fairfield County (Gold Coast)
Generally the lowest mill rates in the state, particularly in the coastal towns. Greenwich, Darien, Westport, New Canaan and Wilton all have mill rates under 20. However, home prices are among the highest in the Northeast so actual tax bills can still be substantial.
Best for: Buyers who can afford higher home prices and want to minimize the tax rate on their investment.
Hartford County
Wide variation within the county. Suburban towns like Simsbury, Avon and Glastonbury have moderate mill rates (25-35 mills), while Hartford itself has the state's highest rate (69 mills). West Hartford, a popular family community, has a mill rate around 41 mills.
Best for: Buyers seeking suburban amenities with easier Hartford commutes.
New Haven County
Similar pattern to Hartford County. Coastal towns like Madison, Guilford and Branford have lower mill rates (20-30 mills), while New Haven, Waterbury, and Hamden have rates above 40 mills. Milford and Orange offer moderate rates with good access to both New Haven and Fairfield County.
Best for: Buyers working in New Haven who want lower taxes should look at shoreline communities or towns like Orange, Woodbridge or Bethany.
Litchfield County
Northwest Connecticut has some of the state's lowest mill rates. Washington, Salisbury, Sharon and Cornwall all have rates under 15 mills. These are rural communities with lower service demands and significant second home populations that expand the tax base.
Best for: Buyers seeking rural living, second homes or remote work flexibility who don't need daily access to employment centers.
New London County
Southeastern Connecticut offers moderate mill rates generally in the 25-40 range. Groton, Stonington and Old Lyme are popular choices. The presence of the Naval Submarine Base and Electric Boat provide economic stability.
Best for: Buyers with ties to the defense industry or seeking shoreline living at lower prices than Fairfield County.

Connecticut municipalities rely heavily on property taxes to fund local services such as public schools. Unlike states that use county level taxation or have broader tax bases, Connecticut's 169 towns each set their own budgets and mill rates. The state also has limited revenue sharing meaning towns must generate most of their own funding.
A mill rate is the amount of tax per $1,000 of assessed property value. One mill equals $1 of tax per $1,000. Connecticut mill rates typically range from about 11 mills in wealthy towns to nearly 70 mills in some cities.
Connecticut properties are assessed at 70% of fair market value. So a home worth $500,000 has an assessed value of $350,000. Your tax bill is the assessed value divided by 1,000, multiplied by your town's mill rate.
State law requires towns to revalue all properties at least every five years. Some towns do it more frequently. During a revaluation assessed values are adjusted to reflect current market conditions which can significantly change your tax bill.
Yes. If you believe your property is over assessed you can file an appeal with your town's Board of Assessment Appeals. You'll need to provide evidence that the assessed value exceeds 70% of your home's fair market value through comparable sales data or an independent appraisal.
