Northampton County property tax records are searchable online through the county’s public records portal at ncpub.org, where you can look up any parcel by address, parcel number, owner name, or recent sale. Each record shows the assessed value, property classification, current billing status, and the millage rates applied by the county, municipality, and school district. For records that aren’t online or questions the portal can’t answer, the Assessment Office at 669 Washington Street in Easton handles walk-in and phone requests.
Searching the Online Portal
The property records site lives at ncpub.org, separate from the main county website. You can search four ways: by street address, by parcel number, by recent sales, or through an advanced search that combines fields. A map-based search is also available if you know roughly where the property sits but not its parcel details.
Address search is the simplest starting point. Just confirm the municipality before you search, because street names repeat across the county’s townships and boroughs. Parcel numbers follow a map-block-lot structure and appear on any prior tax bill or deed. If you’re searching by owner name, use the legal name exactly as recorded; a middle initial or a misspelling can return nothing.
For anything the portal doesn’t answer, the Assessment Office is at the Northampton County Government Center, 669 Washington Street, Easton, PA 18042, and reachable at 610-829-6155.1Northampton County, PA. Assessment Office
What Each Record Contains
Every parcel record shows the assessed value the county uses to calculate the tax bill. Northampton County runs a base-year assessment system, which means the value reflects property conditions and market data from a fixed reference year rather than today’s market. Assessed values and current sale prices can differ substantially, so the number on the record is not an appraisal. The methodology is set by Pennsylvania’s Consolidated County Assessment Law.2Pennsylvania General Assembly. Pennsylvania Consolidated Statutes Title 53 Chapter 88 Section 8801
The record also lists the property’s classification (residential, commercial, or industrial), which affects tax rates and eligibility for certain exclusions. Alongside that, you’ll see the current billing status showing whether taxes are paid, still within the payment window, or delinquent, and a breakdown of the millage applied by each taxing body: the county, the municipality, and the school district.
How Millage Turns Into a Bill
Your bill is assessed value multiplied by the combined millage rate. One mill equals one dollar of tax per $1,000 of assessed value. Three separate taxing bodies set their own rates every year, and the sum drives the annual bill.
As of July 2025, the county portion is 10.8 mills. Municipal and school rates vary widely by location, and the school portion is usually the largest. A property assessed at $50,000 in Allen Township, where the combined rate totals 74.32 mills, would owe roughly $3,716 for the year. The full table of rates for every municipality is published by the county and linked from the records site.3Northampton County Tax. Millage Rates as of July 1, 2025
Reading the Billing Status
Pennsylvania’s Local Tax Collection Law sets a three-tier payment structure that Northampton County follows, and the record’s billing status reflects where the bill sits within it. When a tax bill goes out, you get a discount period of roughly two months during which you can pay at a 2% reduction. After that closes, the face amount is due for another two-month window. Once that window passes, a 10% penalty is added. The exact dates print on each year’s bill and can vary by taxing body.
If the bill still isn’t paid by December 31, the account becomes delinquent and moves to the county’s Revenue and Tax Claim Office, where additional fees and interest accrue. Delinquent accounts should be handled directly with the Revenue Office at 610-829-6186.4Northampton County, PA. Pay My Bill
Paying Online
Current-year real estate taxes can be paid through the county’s portal at norcopa.gov by credit card or e-check. Both carry a convenience fee: 3.5% for credit cards, and $4 for e-checks under $29,999. On a $3,000 bill, the credit card fee alone adds $105, so e-check is the cheaper option for most homeowners.4Northampton County, PA. Pay My Bill
Only current taxes are handled online right now. The county has indicated that past-due accounts less than two years behind and not subject to sale may become available for online payment later in 2026. Until then, past-due balances have to be settled through the Revenue Office directly.4Northampton County, PA. Pay My Bill
Delinquent Accounts and Tax Sales
Unpaid taxes eventually become liens, and unresolved liens can lead to the property being sold at public auction. Northampton County holds two kinds of sales: an upset sale, which is the first attempt to recover delinquent taxes, and a judicial sale, which follows if the property doesn’t sell or the debt isn’t cleared. Bidders have to register with the county before either sale.5Northampton County, PA. Judicial and Upset Sale Information
If a record you’re checking shows a delinquent balance, contacting the Revenue Office early is the practical move. Payment arrangements are easier to set up before an account is scheduled for sale than after.
Keeping the Mailing Address Current
The mailing address on the record is where tax bills go, and a bill sent to an old address doesn’t pause any deadline. To change it, Northampton County requires a written request using the Address Change Request Form from the county’s frequently used forms page. Submit the completed form in person at the Government Center or by mail to the Assessment Office at 669 Washington Street, Easton, PA 18042.6Northampton County, PA. Frequently Used Forms
Update the address well before the next billing cycle. If a bill goes to the wrong place and you miss the discount period or the face-amount window as a result, the penalty still applies.
Related Programs Worth Knowing About
A few things the records portal won’t show you, but that shape what you actually owe: the homestead and farmstead exclusions can reduce the school-tax portion of your assessment for qualifying owner-occupied homes and working farms, with a March 1 application deadline through the county. Pennsylvania’s Property Tax/Rent Rebate Program pays rebates of $380 to $1,000 to eligible homeowners and renters age 65 or older, widows and widowers 50 or older, and people with disabilities 18 or older, subject to income limits. And if the assessed value on your record looks wrong, you can file a challenge with the Northampton County Revenue Appeals Board. Each of those has its own forms, deadlines, and eligibility rules worth checking directly before you rely on them.
