Hartford mill rate: what it is, how it's set, and what you pay

Last updated 2026-07-09

What is a mill rate and how does it work in Hartford?

A mill rate is the tax you owe per $1,000 of assessed value. One mill equals $1 of tax for every $1,000 assessed. Hartford's mill rate for fiscal year 2024-25 is 68.95 mills ^[1].

Connecticut law sets assessed value at 70% of fair market value. That ratio comes from Connecticut General Statutes Section 12-62a, which requires that real property be assessed at "seventy per cent of its present true and actual value" ^[2]. So getting to your bill takes three steps. Find the assessor's market value estimate. Multiply by 0.70 to get assessed value. Then multiply by the mill rate as a decimal (mills divided by 1,000).

Here's the whole formula in one table:

Step	Calculation	Example
Market value (appraised)	Assessor's estimate	$200,000
Assessed value	Market value × 0.70	$140,000
Mill rate (decimal)	68.95 ÷ 1,000	0.06895
Gross tax bill	Assessed value × decimal rate	$9,653
After exemptions	Subtract exemption savings	Varies

That $9,653 is before exemptions. Veterans, seniors, and disabled homeowners can each knock real money off that number. The exemptions section below covers who qualifies for what.

What is Hartford's current mill rate?

Hartford's adopted mill rate for fiscal year 2024-25 (July 1, 2024 through June 30, 2025) is 68.95 mills ^[1]. The City Council sets it each spring, usually in May or early June, when it passes the municipal budget.

The Connecticut Office of Policy and Management publishes a statewide mill rate table every year. For the 2023 grand list year, which drives 2024-25 taxes, Hartford sat at the top of the state alongside Waterbury (60.21 mills) and Bridgeport (54.37 mills) ^[3]. Most suburban Connecticut towns land between 25 and 40 mills. Hartford's rate runs roughly two to three times higher than Glastonbury (34.71 mills) or Simsbury (34.18 mills), both near Hartford County ^[3].

The result is blunt. A $200,000 home in Glastonbury carries a gross bill around $4,860. The same appraised home in Hartford generates a bill around $9,653. Same house, same county, nearly double the tax.

Why is Hartford's mill rate so high compared to other Connecticut towns?

Hartford's high mill rate is not a budgeting mistake. It reflects a structural mismatch that's been building for decades.

Start with the taxable grand list, which is unusually small for a city this size. A large share of Hartford's land belongs to tax-exempt owners: hospitals, universities, state government buildings, and nonprofits. City officials have estimated that roughly half of Hartford's property is exempt from taxation ^[4]. That pushes the entire burden onto a smaller pool of taxable properties, which drives the rate up for everyone left paying.

Hartford's population also skews toward lower-income households, which holds down residential values and shrinks the taxable base further. Meanwhile the city spends heavily on schools, public safety, and municipal services.

Connecticut's education funding formula (the Education Cost Sharing grant) sends Hartford money, but not enough to close the gap between what the city spends and what it can raise. State aid keeps the mill rate from being even worse than it is.

Then there's the history. Hartford came close to bankruptcy in 2017 before the state stepped in with a restructured aid package ^[4]. That shadow hangs over every budget cycle. The city has little room to cut without hurting services residents rely on, and no fast way to grow the grand list.

How does Hartford's mill rate get set each year?

The mill rate runs on a fixed annual calendar tied to the grand list and the city budget. It is not a number someone picks. It's a quotient.

The assessor finalizes the grand list as of October 1 each year. That grand list is the total assessed value of all taxable property in Hartford. The finance department then builds a proposed budget for the Mayor and City Council. The Council holds public hearings in spring and adopts a final budget, which sets total spending. Take total spending, subtract other revenue like state aid and fees, divide by the grand list, and you have the mill rate needed to balance the books ^[5].

So the direction of the rate depends on two moving parts. If the grand list grows through new development or rising values, the mill rate can hold flat or even drop while raising the same money. If the grand list stalls while spending climbs, the rate goes up.

Hartford's grand list has grown modestly in recent years, which has slowed the rate's climb. The city's 2023 grand list came to roughly $3.5 billion in assessed value ^[1].

How do I calculate my Hartford property tax bill?

Pull your property record card from the Hartford Assessor's office or the city's online property search. The card lists your assessed value directly, already set at 70% of the appraiser's market estimate. Don't apply the 70% factor a second time. The assessed value line is your starting point.

The math is short:

Tax bill = (Assessed Value ÷ 1,000) × Mill Rate

So with an assessed value of $98,000:

($98,000 ÷ 1,000) × 68.95 = $6,757.10 gross tax

If you qualify for a state elderly or disability credit or a local exemption, subtract that benefit from the gross tax. The assessor's office can tell you which programs apply to you.

Hartford bills property taxes twice a year. The first installment is due July 1, the second is due January 1, with a 30-day grace period on each ^[5]. Interest on unpaid amounts runs at 1.5% per month (18% annually), the maximum Connecticut allows under Connecticut General Statutes Section 12-146 ^[2].

What exemptions can reduce a Hartford property tax bill?

Several exemptions cut what you owe. Each has its own eligibility rules and deadline, so check dates with the assessor before you count on anything.

Veterans' exemption: Connecticut's base veterans' exemption takes $1,500 off assessed value, which saves about $103 a year at 68.95 mills. Disabled veterans get a larger benefit, and surviving spouses may qualify ^[2].

Elderly and totally disabled tax relief (state program): Connecticut's state circuit breaker gives qualifying homeowners a credit against local tax. Income limits and benefit amounts adjust yearly. For the 2024 grand list year, the program covers single filers with income up to $49,100 and married filers up to $60,100, with credits from $150 to $1,250 depending on income tier ^[6]. Apply through Hartford's Assessor's office by May 15.

Hartford's local elderly freeze: The city runs a local freeze that caps a qualifying senior's tax at the amount owed the year they first qualified, so the bill holds steady even if the mill rate rises. Income limits apply. Ask the assessor for current thresholds.

Disabled homeowners: A parallel state program covers totally disabled persons under the same income limits as the elderly program.

Manufactured housing: Mobile homes assessed as real property may qualify for different treatment in some cases. Confirm with the assessor.

Commercial owners get none of these. Their only lever is appealing the assessment itself, which the next section covers.

Can I appeal my Hartford assessment to lower my tax bill?

Yes. Appealing your assessment is the most direct way to lower your bill without waiting for a mill rate cut that may never come.

Your assessment is set as of October 1 each year. If you think the assessor's market value estimate runs too high, you have two paths. First, ask the assessor's office for an informal review, usually in fall or winter after your assessment notice arrives. Second, file a formal appeal with the Hartford Board of Assessment Appeals (BAA).

The BAA meets in March ^[5]. The written appeal deadline is generally February 20 for real property, though the exact date shifts slightly with the calendar some years, so confirm it with the city clerk. You file on the standard BAA form from the assessor's office and either appear in person or submit written evidence.

Winning cuts your assessed value, which cuts your tax at whatever the mill rate is. A $20,000 reduction in assessed value at 68.95 mills saves $1,379 a year, every year, until the next revaluation.

Your best evidence is a recent appraisal from a licensed Connecticut appraiser, or at least three to five comparable sales (comps) that point to a lower market value than the assessor used. The board is supposed to defend the assessment, but in practice you need something concrete on the table.

If the BAA rules against you, you can appeal to Superior Court within two months of the decision under Connecticut General Statutes Section 12-117a ^[2]. Court appeals get expensive fast, so they make sense mainly for commercial properties or large residential gaps.

Doing this yourself is realistic for most homeowners. A structured appeal kit, like the one at TaxFightBack, walks you through pulling comps and building your BAA presentation without handing a contingency firm 30 to 40% of your first year's savings.

When does Hartford reassess property values (revaluation schedule)?

Connecticut law requires each town to revalue all property at least every five years, with a full revaluation using physical inspection at least every ten years ^[2]. Hartford completed a revaluation for the October 1, 2021 grand list, which put the next full revaluation due by October 1, 2026.

Revaluations matter because they reset assessed values to current market conditions. If your neighborhood's values climbed between 2021 and 2026, your assessed value jumps in the next cycle and your bill rises even if the mill rate holds flat.

The years between revaluations are an opening. If your property's market value has fallen relative to what the assessor has on the books, you can appeal to correct the assessed value before the next revaluation locks in a new number. If the market has risen and your assessment hasn't caught up yet, brace for a bigger bill after the reval.

After a revaluation year, cities often lower the mill rate to offset rising assessments, so the average homeowner doesn't get hit with a huge jump. That's called revenue-neutral ratemaking. Connecticut doesn't require it.

How does Hartford's mill rate compare to other Connecticut cities?

The Connecticut Office of Policy and Management publishes mill rates for all 169 municipalities every year. Here's a snapshot of major cities and selected suburbs for the 2023 grand list (FY 2024-25) ^[3]:

Municipality	Mill Rate (FY 2024-25)
Hartford	68.95
Waterbury	60.21
Bridgeport	54.37
New Haven	43.88
New Britain	49.50
Glastonbury	34.71
Simsbury	34.18
West Hartford	41.80
Greenwich	11.28
Darien	16.80

These figures come from OPM's published table for the 2023 grand list year ^[3]. Verify the current rate with the municipality before you rely on it for planning, since rates are set annually.

The spread is extraordinary. A Greenwich owner pays about 16 cents in tax for every dollar a Hartford owner pays on the same assessed value. That gap reflects differences in grand list size, spending needs, and reliance on state aid, not the quality of local government.

What is Hartford's grand list and why does it matter?

The grand list is the total assessed value of all taxable property in the city, compiled by the assessor as of October 1 each year. It has three parts: real property (land and buildings), personal property (business equipment and machinery), and motor vehicles.

The grand list is the denominator in the mill rate calculation. A bigger grand list means the same revenue can be raised at a lower rate. Hartford's growth here has been held back by the city's heavy share of tax-exempt property and flat residential values in many neighborhoods.

For a single homeowner, the grand list matters indirectly. New development grows the list and can stabilize or lower the rate. If anchor employers leave or exempt institutions expand, the rate rises on everyone still taxable.

The assessor publishes the grand list each January, after the October 1 assessment date. The Finance Department uses the preliminary list to model mill rate scenarios during budget season. You can request the grand list abstract from the assessor's office, and in many years it's posted on the city's website.

What happens if I don't pay Hartford property taxes?

Unpaid Hartford property taxes accrue interest at 1.5% per month from the due date, set by Connecticut General Statutes Section 12-146 ^[2]. That's 18% a year. On a $9,000 bill, a year of non-payment adds $1,620 in interest alone.

Stay delinquent long enough and the city can place a tax lien on the property. Connecticut lets municipalities enforce those liens through foreclosure. The city rarely moves fast on a first-year delinquency, but by year two or three, enforcement becomes a real risk. A Connecticut tax lien takes priority over most other claims, including mortgages recorded after the lien date.

If you're struggling to pay, call the Hartford Tax Collector's office about a payment plan before the bill goes deeply delinquent ^[9]. Connecticut also runs a separate relief program for qualifying elderly renters, worth checking if you rent rather than own ^[6].

Homeowners facing genuine hardship can look into additional state assistance through the Connecticut Department of Housing, though those programs are narrower than the assessor-administered exemptions.

Frequently asked questions

What is Hartford CT's mill rate for 2024-25?

Hartford's mill rate for fiscal year 2024-25 is 68.95 mills. You owe $68.95 for every $1,000 of assessed value. Connecticut law sets assessed value at 70% of market value. So a home with a $200,000 appraised value has an assessed value of $140,000 and a gross tax bill near $9,653 before any exemptions.

How do I find my Hartford property's assessed value?

Use the City of Hartford's online property search through the Assessor's office, or visit the office at 550 Main Street. Your fall assessment notice also lists the assessed value. That figure is already at 70% of the appraiser's market estimate, so you apply the mill rate directly to the assessed value on the card, no further discount needed.

When is the deadline to appeal a Hartford property tax assessment?

The written appeal deadline to the Hartford Board of Assessment Appeals is generally February 20 for real property, with hearings held in March. Missing it almost certainly waives your appeal rights for that tax year. Confirm the exact date with the Hartford City Clerk each year, since it can shift by a day or two around weekends.

Does Hartford offer any property tax exemptions for seniors?

Yes. Connecticut's state elderly circuit breaker gives credits of $150 to $1,250 for qualifying homeowners with income under $49,100 (single) or $60,100 (married). Hartford also runs a local senior freeze that caps your tax at the amount owed when you first qualified. Apply by May 15 through the Hartford Assessor's office. Income limits apply to both programs.

Why is Hartford's mill rate so much higher than surrounding towns?

Roughly half of Hartford's land belongs to tax-exempt owners: hospitals, universities, and state government buildings. That shrinks the taxable grand list while spending needs stay high. The remaining taxable properties carry a disproportionate share of the load, which is why the rate runs two to three times higher than most suburban Connecticut towns.

How often does Hartford reassess property values?

Connecticut requires revaluation at least every five years, with a full physical-inspection revaluation at least every ten years. Hartford completed a revaluation for the October 1, 2021 grand list. The next is due by October 1, 2026. After a revaluation, the city usually adjusts the mill rate to offset the average change in assessments.

What is the interest rate on late Hartford property tax payments?

Interest runs at 1.5% per month (18% a year) on delinquent Hartford property taxes, the maximum set by Connecticut General Statutes Section 12-146. On a $9,000 bill unpaid for one year, that's $1,620 in interest alone. The city can also place a tax lien on the property and eventually pursue foreclosure.

What evidence should I bring to a Hartford Board of Assessment Appeals hearing?

The strongest evidence is a recent appraisal from a licensed Connecticut appraiser. If you'd rather skip that cost upfront, bring three to five recent sales of similar properties (comps) that support a lower market value than the assessor used. Print the property record cards for your comps from the assessor's database. A clear, organized presentation carries weight.

Do motor vehicles get taxed at Hartford's mill rate?

Yes, but Connecticut caps the motor vehicle mill rate at 32.46 mills statewide, no matter how high a town's real property rate is. The cap protects vehicle owners in high-rate cities like Hartford from paying the full 68.95 mills on their cars. The state sends grants to municipalities to make up for the capped revenue.

Can commercial property owners appeal Hartford assessments?

Yes. Commercial owners use the same BAA process as homeowners, with the same February deadline and March hearings. For commercial property, income-approach appraisals built on actual rent rolls and capitalization rates often carry more weight than sales comps. If the BAA denies the appeal, commercial owners can escalate to Superior Court under CGS Section 12-117a, though litigation costs make that realistic only for larger discrepancies.

What is the assessed value ratio in Connecticut and how does it affect my Hartford tax bill?

Connecticut sets assessed value at exactly 70% of market value statewide, by statute. That's the assessment ratio. You apply the mill rate to assessed value, not market value. So a property appraised at $300,000 is assessed at $210,000, and at 68.95 mills the gross tax is $14,479.50. If the assessor's market estimate is wrong, appealing it lowers both the assessed value and the tax.

Is there a veterans' property tax exemption in Hartford?

Yes. Connecticut's base veterans' exemption cuts assessed value by $1,500, saving roughly $103 a year at Hartford's current rate. Disabled veterans qualify for larger reductions, and surviving spouses may be eligible. Apply through the Hartford Assessor's office. Some Connecticut municipalities add local grants for veterans, so confirm current offerings directly with the assessor.

How do I get Hartford to lower my mill rate?

You can't lower the mill rate yourself. The City Council sets it every year through the budget. What you can do is lower your own assessed value through an appeal, which cuts your bill at whatever rate is in effect. Collectively, residents can attend budget hearings and push for lower spending or more non-tax revenue. Growing the taxable grand list through development also dilutes the rate over time.

Where can I find the official Hartford mill rate history?

The Connecticut Office of Policy and Management publishes a historical mill rate table for all 169 municipalities on its website. Hartford's Finance Department also publishes budget documents with rate history. The assessor's office can provide point-in-time figures for specific tax years. Use OPM or city sources directly, since third-party sites sometimes carry outdated numbers.
