Montville property tax in Connecticut runs at 28.87 mills for fiscal year 2025–2026, which works out to $28.87 in tax for every $1,000 of assessed value. Assessed value is 70% of fair market value, not the full price your property would sell for. The town taxes three things: real estate, registered motor vehicles, and business personal property. A home with a $300,000 market value carries a $210,000 assessment and an annual tax bill of $6,062.70 at the current rate.1Town of Montville. Taxes
How Your Bill Is Calculated
Every Montville tax bill starts from two numbers. The first is the assessed value, which Connecticut law fixes at 70% of the property’s present true and actual value.2Justia. Connecticut Code 12-62 – Revaluation of Real Property The second is the mill rate, set each year by the town based on its approved budget and the total value of the grand list. Multiply the assessment by the mill rate and divide by 1,000, and you have your annual tax.3State of Connecticut Office of Policy and Management. Mill Rates
Real estate covers land and permanent structures. Motor vehicles include cars, trucks, and motorcycles registered with the state. Personal property is a business category, covering equipment, machinery, furniture, and fixtures. Unregistered vehicles kept on your property are taxed as personal property, not motor vehicles.4Town of Montville. Assessor’s Office
The grand list is finalized as of October 1 each year. Bills based on that list are mailed the following summer.
Payment Deadlines
Montville’s fiscal year runs July 1 through June 30. Motor vehicle and personal property taxes are due in full on July 1. Real estate taxes can be paid in two installments, the first on July 1 and the second on January 1. Real estate bills of $100 or less are the exception; those must be paid in full with the July installment.5Town of Montville, CT. Tax Collection
Each installment has a grace period through the end of the month. A bill due July 1 does not draw a late charge until after July 31. If the 31st falls on a weekend or holiday, the deadline extends to the next business day. The January installment works the same way.1Town of Montville. Taxes
Ways to Pay
You can mail a check in the envelope that came with your bill, pay online through the town’s portal with a credit card, debit card, or electronic check, or pay in person at Town Hall during business hours. If you pay in person, bring the full bill so the clerk can validate a receipt.
One caveat matters if you are close to a deadline or need a DMV release: electronic check payments carry a 10-business-day hold. A debit or credit card clears faster.6Town of Montville, CT. Paying Taxes Online
What Happens If You Pay Late
Once the grace period ends, interest runs at 1.5% per month, or 18% a year. It is calculated from the original due date, not from the end of the grace period, and any partial month counts as a full month. Connecticut law sets a $2 minimum interest charge per installment.7Justia. Connecticut Code 12-146 – Delinquent Tax or Installment, Interest, Waiver of Interest Miss the August 1 cutoff on a $3,000 real estate installment and you have already accrued two months of interest by the time you pay in September, roughly $90.
Unpaid real estate taxes do more than accumulate interest. A lien attaches to the property automatically when the tax goes delinquent, and that lien takes priority over almost all other mortgages and encumbrances. The tax collector can continue the lien by filing a certificate with the Town Clerk, keeping it in force for up to 15 years. If it is not continued, the lien lapses after two years. Prolonged nonpayment can lead to foreclosure and a public sale of the property.
Business Personal Property: A Separate Deadline
If you run a business in Montville, or you keep an unregistered vehicle on your property, you have to file a Personal Property Declaration with the Assessor by November 1 each year.8Justia. Connecticut Code 12-41 – Filing of Declaration The declaration lists each item’s description, acquisition date, and original cost, and the Assessor applies a depreciation schedule to arrive at the assessed value.4Town of Montville. Assessor’s Office
Miss the deadline and Connecticut law imposes a flat 25% penalty on the assessed value of anything not declared on time. The same penalty applies to property left off a declaration that is later discovered.8Justia. Connecticut Code 12-41 – Filing of Declaration On $50,000 of equipment, that is thousands of dollars in penalty on top of the tax.
Supplemental Motor Vehicle Bills
Register a vehicle after the October 1 assessment date but before the following August 1, and you will receive a separate supplemental motor vehicle tax bill. It is prorated for the portion of the year you owned the vehicle. If the new vehicle replaced one you had already registered, you may see a credit for the old vehicle’s remaining assessed value. The supplemental bill is due January 1, not July 1.
Exemptions and Tax Relief
Montville honors several state programs that reduce what homeowners owe. Each has its own form and deadline.
Veterans
Wartime veterans, and veterans with at least 30 years of service, qualify for a basic property tax exemption of $1,000 in assessed value under state law. To claim it, file your DD-214 (honorable discharge papers) with the Town Clerk before October 1. Filing is a one-time step, but the October 1 date matters because exemptions apply to the grand list as of that date. Montville may offer additional local veterans exemptions tied to income under its municipal authority.9Justia. Connecticut Code 12-81f – Municipal Option to Provide Additional Veterans Exemptions
Elderly and Disabled Homeowners
Connecticut’s circuit breaker program provides a property tax credit to homeowners who are 65 or older, or totally disabled, and whose income falls within a graduated state scale. The maximum credit is $1,250 for married couples and $1,000 for single filers. Applications go to the Assessor’s Office between February 1 and May 15, with proof of income such as a federal tax return or Social Security statement.10State of Connecticut Office of Policy and Management.

Disagreeing With Your Assessment
If the number on your assessment looks too high, start informally with the Assessor’s Office. Errors in the property record, like the wrong square footage or an unrecorded note about damage, can often be fixed without a formal appeal.
If that does not settle it, file a written appeal with Montville’s Board of Assessment Appeals by February 20. The appeal has to include your name, a description of the property, the reason you disagree with the assessment, and your own estimate of value.11Justia. Connecticut Code 12-111 – Appeals to Board of Assessment Appeals The board will schedule a hearing and send notice at least seven days in advance. Bring your evidence: recent comparable sales, a professional appraisal if you have one, photographs of the property’s condition, and your property record card from the Assessor.
If the board rules against you, Connecticut law allows a further appeal to Superior Court, and for residential property to the state’s Office of the Property Tax Ombudsman. Keep paying your taxes while any appeal is pending. An open dispute does not pause the obligation, and interest keeps running on anything you leave unpaid.
