2026 Town and County tax rates are published by town and taxing district; no single countywide effective rate verified.

Statement mailing

Published

January 1 for town and county bills; March 1 for Village of Fort Ann; June 1 for other village bills; September 1 for school bills.

Payment deadline

Published

2026 schedule verified: town/county bills January 1, Village of Fort Ann March 1, other village bills June 1, and school bills September 1; payment deadlines are administered by the applicable collector.

Valuation protest

Published

Fourth Tuesday in May 2026 is the usual Grievance Day; Washington County says owners must confirm the exact date and time with the town assessor.

Do not assume a grace period.

The reviewed record identifies the payment timing above but does not establish a universal penalty schedule for this page. Late charges, interest, collection costs, tax-sale procedures, and lien or foreclosure timelines can depend on state law and the local collector’s process. If the deadline is close or a balance is delinquent, contact the tax collector directly and request the current payoff amount in writing.

Treat a published payment deadline as a hard operational date and retain your receipt or confirmation number.

From assessment to collection

01Valuation and notice

Review the assessment notice as soon as it arrives. The protest window may run from the notice date rather than from the payment due date.

02Statement and account review

Match the tax statement to the parcel or account number and confirm exemptions, assessed value, taxing units, credits, and balance.

03Payment confirmation

Use the official collector channel, then save the receipt, transaction reference, and date posted. A bank submission is not always the same as a county posting date.
