The Erie County PA tax map is available free online through the county’s GIS Parcel Viewer, where you can search by street address or by a property’s 14-digit parcel index number to see boundary lines, lot dimensions, acreage, and links to the assessment and tax record for any parcel in the county.1Erie County, PA. Geographic Information System You can reach it through the county’s main GIS page at eriecountypa.gov or directly through the ArcGIS hub at ecgis-eriecopa.hub.arcgis.com.
Find the Parcel Index Number First
Searches go faster if you have the parcel index number in hand. It’s a 14-digit code assigned to every tract of land in Erie County, and it ties the map record to the assessment and tax history.2Erie County eGovPlus. Property Tax Search When you type it into the county’s online tools, enter only the digits. No spaces, no periods, no dashes.
If you don’t know the number, check the top of your most recent property tax bill, where it appears alongside the legal description and the municipality. Your recorded deed also lists it; deeds are kept by the Erie County Recorder of Deeds.3Erie County Courts. Recorder of Deeds Knowing the correct municipality helps too. Erie County contains dozens of boroughs and townships, and street names repeat across them.
You can also search by address alone in the Parcel Viewer if the number isn’t handy, then pull the parcel number from the record once you’ve found the lot.
Using the Parcel Viewer
The county has made its GIS data public at no cost so property owners and buyers can see how land is mapped and assessed.1Erie County, PA. Geographic Information System Once the viewer loads, enter the parcel number or address in the search box. The map will zoom to the lot and outline it.
From there, a few controls do most of the work. You can zoom from a neighborhood view down to an individual lot. The layer toggle switches the background from a simple line-drawn map to aerial satellite imagery, which lets you see actual terrain, tree cover, driveways, and structures on the ground. Additional overlays can be turned on for zoning classifications, flood zones, and roads.
Clicking directly on a parcel opens basic information for that lot. For deeper data — assessed value, tax amount, payment history — the county runs a separate Property and Tax Search tool that works from the same parcel number.4Erie County, Pennsylvania. Property and Tax Search
One limit to know about: the county charges a $100 fee to unlock property owner information on its online portal, and you need a registered logged-in account to see it. If you just want to look at boundaries, acreage, and tax figures, the free Parcel Viewer and the public tax search give you that without the fee.
What the Tax Map Shows, and What It Doesn’t
The map itself is a spatial record. It shows where one property ends and the next begins, the dimensions of the lot, and the total acreage. These maps are maintained to keep accurate property descriptions tied to the county’s assessment roll.
The map alone won’t tell you what a property is worth or what it pays in taxes. That lives in the assessment record you reach through the parcel number: assessed value of the land, assessed value of any structures, year built, square footage, and general characteristics of the improvements. That’s the data that drives tax bills.
One figure worth keeping in perspective: Erie County’s assessed values sit well below current market values. The State Tax Equalization Board publishes a common level ratio each year that reflects the gap. For the period from July 2025 through June 2026, the ratio is 1.88, meaning assessed values run at roughly half of fair market value. So an assessed value of $100,000 on the map record does not mean the property would sell for $100,000.
Your actual tax bill is calculated by applying three separate millage rates to the assessed value: one set by the county, one by your municipality, and one by your school district. The Erie County Department of Assessment publishes a combined millage rate schedule for every jurisdiction each year.5Erie County, PA. Documents and Forms One mill equals $1 of tax per $1,000 of assessed value, so a $100,000 assessment in a jurisdiction with 30 combined mills yields $3,000 a year.
When You Need a Certified Copy
A screenshot from the Parcel Viewer is fine for most personal use. It isn’t enough for a court filing, a mortgage application, or a surveyor’s work. For those, you need a certified paper copy from the Erie County Department of Assessment at the courthouse.6Erie County, Pennsylvania. Erie County Department of Assessment You can visit in person during business hours or call the office at 814-451-6225 to ask about mailing and current fees.
Certified copies carry the weight of an official county record, which is what title companies, surveyors, and courts generally require. Assessment office staff can also help if what you see online conflicts with older paper records. The department’s documents and forms page has downloadable resources including the current millage schedule, appeal forms, and homestead exclusion applications.5Erie County, PA. Documents and Forms
If the Map or Assessment Looks Wrong
If the assessed value tied to the parcel looks too high, you can file a formal appeal with the county. The window runs from January 1 through August 1 each year, and the filing fee is $50 per parcel.7Erie County, PA. Notice of Intention to Appeal Property Assessment If a boundary line on the map itself appears wrong, start with the assessment office; they can tell you whether it reflects the recorded deed or needs correction from a different source.
