2026 fiscal calendar
Know the tax date before it becomes a penalty date.
Tax bills, payment rules, and valuation-review windows are controlled by the local jurisdiction and the governing state framework. The verified record below separates published figures from dates that require confirmation with Dauphin County Office of Tax Assessment.
Effective rate
county, municipal, and school district millage varies; Dauphin County's base year is 2001 and its assessment ratio is 100%.
Statement mailing
February 1, 2026 for annual county/municipal bills; school district bills are mailed July 1, 2026.
Payment deadline
2026 county real estate tax bill: 2% discount through March 31; face amount through May 31; 5% penalty through July 31; 10% penalty through December 31; unpaid amounts go to Tax Claim after December 31.
Valuation protest
June 1 through August 1, 2026 for annual assessment appeals; hearings are conducted August 1 through October 31. Newly revised assessments follow the notice deadline.
Critical payment warning
Do not assume a grace period.
The verified county 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 the published payment deadline as a hard operational date and retain your receipt or confirmation number.
Read the calendar in order
From assessment to collection
1. Valuation 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.
2. Statement and account review
Match the tax statement to the parcel or account number and confirm exemptions, assessed value, taxing units, credits, and balance.
3. Payment 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.
