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 Lehigh County Assessment Office.
Effective rate
county, municipal, and school millage varies by taxing district; official 2026 property records show district-specific millage rather than a single countywide effective rate.
Statement mailing
official Lehigh County sources reviewed do not publish one countywide 2026 current-tax mailing date; municipal collectors administer bills.
Payment deadline
official Lehigh County collector information shows municipal tax authorities set their own 2026 billing and payment schedules; no single countywide discount, face, or penalty deadline was published.
Valuation protest
August 1, 2026 for annual assessment appeals, or the date on the change-of-assessment notice; the original must be received by the deadline and postmarks or fax are not accepted.
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.
