Property Tax

The fiscal year for property tax covers the period from July 1 to June 30. The usual billing dates are as follows:
Quarter Issue Date Due Date
First July 1
August 1
Second October 1
November 1
Third January 1
February 1
Fourth April 1
May 1

If the normal due date falls on a weekend or a holiday, the actual due date is the next business day. Interest at an annual rate of 14% is charged for late payments.

The first and second quarter preliminary property tax bills are estimated based on one fourth of the prior year's net tax, adjusted to reflect the annual 2.5% tax increase allowed under Proposition 2 1/2 plus any other tax increase attributable to approved overrides or exclusions.

The tax rate history can be found here.

The Abatement Process

An abatement application can be filed as soon as you receive your Third Quarter tax bill. The Assessors Office cannot accept applications before those bills are mailed in December. The deadline for filing an abatement application with the Assessors' Office is the due date of the third quarter tax bill (usually February 1.)

Application for Exemption or Deferral

If you qualify for an exemption or a deferral, the deadline for filing an application is April 1. If approved after the issuance of the third quarter tax bills, the entire amount of the exemption will be deducted from the fourth quarter tax bill. If approved earlier, the exemption will be deducted equally from the third and fourth quarter tax bills.

Penalties for Late Payment

Under the quarterly payment system, interest of 14% per annum will be charged for the number of days the payment is overdue after the due date. Timely payment (of all quarterly bills) is generally a prerequisite to preserving an owner's right to appeal an abatement decision of the Board of Assessors.

Property Valuation

In accordance with state law, a town-wide property revaluation is completed in the fall (assessment date of January 1). The assessed values are used to set the new tax rate in December and appear on your third and fourth quarter tax bills.

  • Payments not received in the Tax Collector's Office by 4:30 p.m. on the due date will be subject to interest penalty at the rate of 14% per year, daily basis, from the due date until payment is made.
  • Postmarks do not verify timely payment. Mail early to ensure delivery through the Post Office.
  • Mail payments, payable to "Town of Concord," in the enclosed pre-addressed yellow envelope. Enclose the return copy of the bill with your check. Please do not enclose any other payment in the property tax envelope. If you have a change of mailing address, do not write it on your bill. Please note your property address, your parcel number, and your new mailing address on a separate piece of paper and include it with your payment.
  • If taxes are paid from a bank escrow account, send both copies of your bill to your bank immediately. You may request the bank to make payment in advance of the final due date.
  • Do not enclose cash.
  • Sign and date your check. Do not date the check ahead.
  • Checks cannot be held by the Collector for later deposit. A post-dated check that is processed and not honored by the bank will result in additional charges imposed by the bank and the Town.
