Oregon, WA Property Tax: Lookup, Pay & Rates Guide

Washington County’s Department of Assessment & Taxation handles property valuation, property-tax accounts, annual tax statements and the collection of taxes for many local governments and special districts.

Your tax bill may contain taxes for the county, your city, school district, fire protection, parks, community college, Metro and other applicable districts. The county collects and distributes the taxes according to the property’s location.

The county maintains a central Property Taxes page with separate services to view your account balance, print a tax statement and retrieve payment receipts.

How to look up your current property tax balance

1. Open the Property Taxes homepage. Use the county link above.
2. Find “Pay Your Property Taxes.” This section contains the balance and payment services.
3. Select “View Account Balance.” The county directs users to its account-information service.
4. Use the search method presented. Enter the property tax account number or other supported property identifier.
5. Identify the matching property. Verify the address and account number before relying on a result.
6. Review the balance. Check the tax year, installments, any payments posted and any delinquent amounts.
7. Save the information. Print or download the tax statement when a detailed breakdown is needed.

Where can you find the property tax account number?

Washington County uses a tax account number to identify the property for payment purposes. It appears on the annual property-tax statement.

If the statement is missing, locate your property through the county’s InterMap service, which supports searching by property address, tax lot ID or an R-number account identifier.

1. Open the Property Values & Improvements page.
2. Select Search the InterMap site.
3. Search by street address, Taxlot ID or R number.
4. Select the correct parcel on the map.
5. Scroll to the Additional Information section.
6. Open Assessment & Taxation Information.
7. Record the account information and return to the tax bill lookup.

Washington County accepts online payments by electronic check (ACH) and major debit or credit cards. The county states that online payments involve a six-step process and are not complete merely because you opened the checkout.

Step-by-step online payment instructions

1. Open the county’s Property Tax Payment Methods page. Use the authorized county link below.
2. Find “Pay online.” Review the listed electronic-check and card processing fees.
3. Select “Make a payment online.” This launches the payment service.
4. Enter the property-tax account number. Use the number from your current tax statement.
5. Review the property and amount. Confirm the correct account, installment and tax year.
6. Choose a payment method. Enter your banking information for an electronic check or card information for an eligible card payment.
7. Check the convenience fee. The fee is charged by the payment processor and displayed separately from taxes.
8. Continue through all six payment steps. Review and submit the final confirmation.
9. Save the step-six confirmation page. The county specifically recommends printing the final confirmation for your records.
10. Verify settlement and posting. Electronic-check payments can take several days to process and may fail if account or routing information is incorrect.

Can you pay over the phone?

Yes. Washington County provides an automated telephone payment line:

Have your property-tax account number and card or banking information available. The automated service requires you to complete all prompts and keep the payment confirmation number.

Compare e-check and card costs

Oregon property taxes are generally due in three installments, although owners can pay the full year or the first two-thirds early to receive a discount.

The regular statutory installment dates are November 15, February 15 and May 15. If a due date falls on a weekend or legal holiday, Oregon’s next-business-day rule applies.

*February 15, 2027 is the observed Presidents’ Day holiday and May 15, 2027 is a Saturday. These dates are calculated using the standard next-business-day rule. Always confirm your statement and any county notices before relying on a deadline.

How Oregon’s property-tax discounts work

Example: $6,000 annual property-tax bill

The example assumes all $6,000 qualifies for the stated discounts, no previous delinquency, and no separately billed charges. The actual discount and remaining balance should be taken from the county statement.

Late-payment interest

Washington County states that delinquent property-tax installments accrue interest at a rate of 16% annually, equivalent to approximately 1⅓% per month, with interest applied according to its monthly collection rules.

The county applies payments to the oldest outstanding tax year first. If you owe taxes from several years, a payment intended for the current year may instead be applied to the oldest delinquency.

Washington County does not have one combined property-tax rate for every home. Rates are determined by a property’s tax code area, which represents the combination of local taxing districts serving the parcel.

The county’s 2025–26 release identified 360 separate tax code areas across 64 taxing districts. A home in Hillsboro can have a different combined rate from another property in Beaverton, Tigard or Forest Grove. Different parcels within the same city can also belong to different tax code areas.

How to find your property’s combined rate

1. Find your current Washington County property-tax statement.
2. Locate the tax code area or taxing-district information.
3. Open the official Assessment & Taxation Publications page.
4. Find the current year’s Summary of Assessment & Levy reports.
5. Locate Table 6a — Detail of Code Area Consolidated Billing Rates or another published tax-rate detail report.
6. Match the tax code area on your statement to the report.
7. Review the applicable education, general government and excluded/unlimited components.
8. Compare the rate and resulting taxes with the actual statement.

Rate example from an official county report

A county-published 2025–26 rate detail lists tax code area 015.15, which includes Forest Grove School District and other applicable districts, at a combined rate of 14.2227 per $1,000 of assessed value.

This is a specific historical tax-code-area example, not a countywide average and not a confirmed rate for 2026–27.

Your real tax bill can differ because of different tax code areas, special assessments, Measure 5 compression, local option levies, bond levies and other account-specific conditions.

What are Measure 5 and Measure 50?

Oregon’s property-tax system is governed partly by two major constitutional limitations.

These rules do not mean every tax bill can grow only 3% per year. New levies, bond taxes, changes in property value relationships, new construction and other factors can increase the final billed amount.

Use this estimator with your assessed value and the combined billing rate corresponding to your tax code area. It also allows you to add known non-value-based charges.

You can enter a real market value and maximum assessed value instead if you want to calculate the lower of the two, which is normally the property’s assessed value under Oregon’s Measure 50 framework.

Why the assessed value matters more than purchase price

Oregon property taxes generally are not calculated directly from the price paid for a house.

For example, a home might have a real market value of $550,000 but a maximum assessed value of $320,000. If the county records those values, the assessed value normally is $320,000 because Oregon uses the lower figure.

The tax is then calculated using the applicable property-specific rates and adjustments.

Washington County’s InterMap application allows residents to view general parcel records, assessed values, recorded sales, deed information and improvement details.

InterMap is useful if you do not have your tax bill or need to verify how the Assessor describes your property.

Search InterMap step by step

1. Open Property Values & Improvements.
2. Select the InterMap search link.
3. Choose an available search method: property address, Taxlot ID or R number.
4. Enter the identifier and locate the matching result.
5. Open the parcel’s map location.
6. Scroll to Additional Information.
7. Click the Assessment & Taxation Information subreport.
8. Review the available property and valuation information.
9. Compare the assessment year with your tax statement.

Can your assessed value increase more than 3%?

In certain situations, yes. The 3% rule generally concerns annual growth of Maximum Assessed Value, not a guarantee that every property’s assessed value or tax bill increases by no more than 3%.

If real market value was previously below maximum assessed value, changes in the relationship between the two values can cause assessed value to rise by more than 3%. New construction, partitioning and other property changes also have special rules.

Oregon has several property-tax relief programs, but not every homeowner qualifies for an automatic reduction solely because the property is a primary residence.

Washington County lists specific exemptions and deferral programs for eligible veterans, qualifying surviving spouses, senior homeowners, disabled homeowners and other applicants.

Senior and disabled homeowner deferral

Washington County explains that the Oregon Department of Revenue can pay qualifying homeowners’ property taxes under its senior or disabled homeowner deferral programs.

The deferred amount becomes a debt secured by a lien on the home, and interest accrues. The county’s published FAQ describes 6% interest under the program.

Steps to investigate tax deferral

1. Open the county’s Exemptions and Deferrals page.
2. Choose Senior Deferral or Disabled Homeowner Deferral.
3. Review the current state eligibility and financial conditions.
4. Check the program’s application and renewal deadlines.
5. Prepare the ownership, residency, income and eligibility documents required by Oregon DOR.
6. Complete the official application.
7. Retain confirmation and check whether the program is reflected on your property-tax statement.

Disabled veteran property tax exemption

Washington County states that a veteran with a qualifying disability rating of at least 40%, or an eligible surviving spouse or domestic partner, may qualify for a partial property-tax exemption.

Applicants generally must satisfy Oregon residency, ownership, principal-residence and documentary requirements.

Special Programs: 503-846-8741.

Official Washington County Special Programs ↗

If you disagree with your property’s real market value, maximum assessed value, assessed value or certain other valuation details, you may be able to file an appeal with the Property Value Appeals Board (PVAB).

The county uses the term PVAB; this process was previously known as the Board of Property Tax Appeals (BOPTA).

How to appeal your assessed property value

1. Find the current tax statement. Review the Real Market Value, Maximum Assessed Value and Assessed Value.
2. Identify the precise disagreement. The appeal should focus on valuation or another issue the board is authorized to hear.
3. Gather supporting evidence. Relevant comparable sales, independent appraisals and documentation of factual property errors can help.
4. Open the Property Value Appeals page. Use the official county link below.
5. Choose the correct petition. Real property, personal property and certain other assessment types require different forms.
6. Complete the form. Enter the property identifier, assessment year, requested value and relevant evidence.
7. Submit before the deadline. The county requires the petition to be delivered or postmarked within the authorized period.
8. Retain proof of filing. Keep the petition and supporting documents.
9. Attend the hearing if scheduled. The board provides an opportunity to present evidence under its hearing procedures.

What can the board change?

PVAB can review property values within its statutory authority. It generally cannot simply lower a tax rate because an owner believes the bill is too high, and a reduction in Real Market Value does not automatically produce a reduction in tax.

If Maximum Assessed Value remains below Real Market Value, a smaller but still higher-than-MAV Real Market Value can leave taxable Assessed Value unchanged.

PVAB questions: 503-846-3854.

What if your property taxes are seriously overdue?

Washington County maintains separate delinquency timelines for real property, manufactured structures and business personal property.

Real property can eventually become subject to foreclosure procedures if property taxes remain delinquent under Oregon law. The applicable dates and redemption procedures require account-specific review.

If you have a tax foreclosure or delinquency notice, immediately contact the county at 503-846-8801 rather than relying on a generic online tax estimate.

Drop-box payment locations

The county operates an indoor and outdoor tax-payment drop box at the Public Services Building in Hillsboro.

Mail your property tax payment

Make your check payable to Washington County, include the tax account number and payment stub, and use blue or black ink.

The county recommends including a self-addressed stamped envelope if you want a receipt mailed back.
