Washington County, Mississippi property-tax payment and appeal deadlines
Tax bills, payment rules, and valuation-review windows are controlled by the local jurisdiction and the governing state framework. The reviewed record below separates published figures from items that still require confirmation with Washington County Tax Assessor and Tax Collector (Mark Seard; Patricia Lee).
Rate context
Confirmno single countywide effective rate was published; Washington County millage varies by taxing district.
Statement mailing
Confirmofficial county sources reviewed did not publish a specific 2026 tax-bill mailing date.
Payment deadline
PublishedFor the 2026 tax year, Mississippi property taxes are due February 1, 2027; at least one-half may be paid by that date, and unpaid balances accrue interest and penalties under Mississippi law.
Valuation protest
PublishedFor the 2026 assessment, file a valuation appeal with the county Board of Supervisors by the first Monday in August preceding the tax due date: August 3, 2026.
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.
