Grant County Property Tax Records

Grant County property tax records are available online through the county's PACS property search portal and the Treasurer's office in Ephrata. You can look up current parcel data, view assessed values, pay your tax bill, and access historical records going back to 2010. This page explains the tools Grant County provides for searching and managing property tax records.

Grant County PACS Property Search

The official Grant County property search portal is the Grant County PACS system. This covers current property data from 2024 to the present. You can search by parcel number, property address, or owner name. An Advanced option provides additional filters. Within the application, you can also switch to Sales Search or Map Search for more options. To see the most current ownership, change the Results Display to 2026-2027 when prompted.

Grant County updated to the PACS system in 2024. Before that, the county used the TaxSifter platform. For older property information from 2010 through 2023, use the Grant County legacy TaxSifter archive. This older database still allows searches by parcel, owner, and address and is useful for researching prior-year valuations, ownership history, and historical tax distributions. The archive is maintained as a historical reference. Current and active records are in PACS.

Tax statements can also be downloaded through the Grant County Laserfiche WebLink repository. This system hosts digitized tax rolls and statements that you can retrieve without creating an account. It is organized by repository and database ID for structured access to official county records.

The PACS portal allows parcel searches, sales lookups, and map searches for all Grant County properties.

Grant County Treasurer - Payments and Accounts

The Grant County Treasurer's Office is the custodian of county funds and the main office for property tax collection. The office has seven full-time employees trained to help the public with tax questions and payments. The Treasurer also runs a Tax Statement Download portal where taxpayers can search for 2025 and 2026 tax statements using property ID, parcel number, or owner name. This is useful if you did not receive your mailed statement or need a copy for records.

Online payments are handled through Point and Pay at paydici.com/grant-county-treasurer-wa. The portal accepts credit card, debit card, and electronic check payments around the clock. Credit card payments carry a 2.5 percent fee. Debit card payments have a $3.95 charge. eCheck payments cost $1.00. All fees go to the vendor and are not retained by the county. Payments made online may take three to five business days to post to your account. The Point and Pay helpline is 888-891-6064 if you need payment help.

Returned payments are subject to a $30 returned item fee plus potential additional interest and penalties. Property taxes are due April 30 for the first half and October 31 for the second half. The Treasurer handles legal proceedings to collect past-due amounts, including tax foreclosure actions. Contact the office directly if you are behind on taxes and want to discuss your options before the situation escalates.

The Grant County Public Records page at grantcountywa.gov/235/Public-Records explains how to request physical copies of records and notes that current data is in PACS while older data (2010-2023) is in the legacy TaxSifter archive. Formal public records requests can be submitted through that page as well.

Grant County's Treasurer office manages tax billing, collection, and the online payment gateway for property owners across the county.

Grant County Property Valuation

Property assessments in Grant County are based on 100 percent of market value as required by Washington State law. The Assessor's Office maintains all parcel data including ownership, assessed values, and property characteristics. Washington's general framework for property assessment is set under RCW 84.40, which establishes how all property must be listed and valued. Annual revaluation ensures that assessments reflect current market conditions.

Delinquent taxes in Grant County accrue interest and penalties under RCW 84.56. If taxes go unpaid long enough, the county can begin foreclosure proceedings to collect what is owed. The foreclosure process involves legal steps and public notice. Owners who receive delinquency notices should contact the Treasurer's office promptly to explore payment options before reaching the foreclosure stage.

Exemptions and Property Value Appeals

Washington State has exemption and deferral programs for qualifying senior citizens and disabled persons. Grant County property owners who qualify may see a reduction in their assessed value or be able to defer a portion of their taxes. Income and age requirements apply. Contact the Grant County Assessor's office for application details. The state Department of Revenue covers these programs at dor.wa.gov.

If you disagree with your assessed value, you can appeal to the Grant County Board of Equalization. The Board reviews evidence from property owners and the Assessor. Appeals that are not resolved at the county level go to the Washington State Board of Tax Appeals at bta.wa.gov. File your appeal before the deadline stated on your Change of Value notice.

Note: Check the Grant County PACS portal before your appeal to confirm the values currently on record. Having accurate data ready will help you build your case.
