Washington County Property Tax Guide: Pay, Search, Due Dates & Exemptions
Washington County property taxes are easier to manage when you start with the account record, not the payment screen. A missing statement, old amount, wrong account number, escrow payment, appeal question, or exemption issue can change what you should do next. This guide explains how to search your property, read the tax statement, choose the correct payment method, understand due dates, review tax programs, and avoid late-payment problems before using an official Washington County portal for final action.
Quick Answer
For Washington County property tax help, search your account first, confirm the property and account number, review the current tax statement, check whether your mortgage company requested or paid the bill, verify the payment schedule, then choose the official payment method that fits your situation. Do not pay from an old statement or guessed balance without checking the current account record.
- Open the Washington County property tax information portal.
- Search using your tax account number, property information, or available owner/property search option.
- Confirm the property and tax year before paying.
- Open account balance, tax statement, receipt, payment or appeal information as needed.
Important: Which Washington County Is This?
This guide is written for Washington County, Oregon, handled by Washington County Assessment & Taxation in Hillsboro. Many U.S. states have a Washington County, so always confirm the state and county before paying a tax bill.
Do not pay the wrong county. If your property is in Washington County, Maryland, Minnesota, Utah, Pennsylvania, Arkansas, Wisconsin, or another state, use that county’s own treasurer, collector, assessor, or tax office instead.

Most payment mistakes happen because users move directly to the payment screen. Take a few minutes to confirm the record first.
How to Search Washington County Property Tax Records
The property tax search should be your starting point for account balance, payment status, statement review, receipts, and property tax information. Search before you pay, before you call, and before you assume a lender has handled the bill.
- Open the Washington County tax information portal.
- Use the tax account number if you have it.
- If you do not have the account number, use the available property search options.
- Confirm the correct property and tax year.
- Review balance, statement, payment status, or receipt information.
Best when you have the annual statement, a prior receipt, or mortgage tax paperwork.
Use when the account number is missing. Confirm the property carefully before paying.
Check whether payment has posted before sending a new payment.
Print or save receipts for escrow, closing, tax records, reimbursement, or dispute proof.
How to Pay Washington County Property Tax
Washington County lists several ways to pay property taxes, including online, by phone, by mail, in person, at a drop box, and by bill pay. The best method depends on how close the due date is, whether you need a receipt, and whether your bank or lender is involved.

Washington County Property Tax Due Dates, Discounts and Installments
Washington County property tax statements are generally mailed by October 25. The key due date is November 15. If the 15th falls on a weekend, official guidance says timely payment may carry through the next business day.
| Date / Option | What It Means | Practical Action |
|---|---|---|
| October 25 | Annual property tax statements are mailed on or before this date. | If your statement does not arrive, use the online tax portal instead of waiting too long. |
| November 15: full payment | Full payment by the due date can qualify for a 3% discount. | Best option if you want the discount and can pay the full amount. |
| November 15: two-thirds payment | Two-thirds payment can qualify for a 2% discount, with remaining payment due later. | Good option if you can pay most of the bill but want to split the final portion. |
| November 15: one-third payment | One-third installment starts the installment route, with no discount. | Use if you need to spread payments across the allowed schedule. |
| February 15 | Second installment due date for those using the installment schedule. | Verify posted first installment before paying the second. |
| May 15 | Third installment due date. Real property accounts become delinquent if not paid in full by May 15. | Resolve unpaid balances before delinquency and foreclosure timelines become more serious. |
Interest warning: Official FAQ guidance lists interest on past-due installments at 1.333% monthly, or 16% annually. If a payment is late, check your current account balance before paying because the amount may have changed.
How to Read Your Washington County Property Tax Statement
The tax statement is more than a bill. It helps you understand account information, property values, taxable value, payment choices, due dates, discounts, and whether a tax program appears on the account.
- Open the official sample tax statement page.
- Compare your statement sections with the sample.
- Review Real Market Value, Assessed Value, tax account details and payment options.
- Check whether any veteran exemption or program note appears.
- If value looks wrong, contact appraisal or review appeal options.
RMV is the assessor’s estimate of what the property would sell for as of January 1.
Oregon tax calculation often uses Assessed Value based on Market Value or Maximum Assessed Value, whichever is lower.
The statement shows full-payment, two-thirds and one-third payment options with due dates and discount rules.
If a veteran exemption is already being received, the official sample statement says it will be noted in the statement section.
Why Did My Washington County Property Tax Go Up?
A property tax increase can happen even when you expected a smaller change. Value changes, local levies, bonds, special assessments, changed property use, improvement activity, and Oregon’s assessed-value rules can all affect the final bill.
| Possible Reason | Where to Look | What to Do |
|---|---|---|
| Value changed | RMV, AV and appraisal information on the tax statement. | If the value seems wrong, contact appraisal or review PVAB appeal options. |
| Local levies or bonds changed | Taxing district and levy sections on the statement. | Compare the current statement with last year’s statement. |
| Discount was missed | Payment option and due date area. | Pay by the correct November deadline if you want full-payment or two-thirds discount treatment. |
| Payment became late | Account balance and interest section. | Check live balance because interest can change the amount due. |
| Exemption or deferral not active | Program note section and tax program resources. | Review veteran exemption, active duty exemption, or senior/disabled deferral rules. |
Washington County Property Tax Exemptions and Deferral Programs
Washington County’s property tax program pages include veteran exemption, active duty military service member exemption, senior/disabled deferral, manufactured home information and property value appeals. Read eligibility carefully because a deferral is not the same thing as a permanent exemption.
| Program | Who Should Review It | Practical Step | Official Link |
|---|---|---|---|
| Veteran’s Property Tax Exemption | Disabled veterans and qualifying surviving spouses or registered domestic partners. | Check disability/residency/ownership/primary residence rules and file with supporting documents. | Veteran’s Exemption |
| Active Duty Military Exemption | Qualifying Oregon National Guard or Reserve members with qualifying federal active duty service. | Review service period and filing instructions before assuming eligibility. | A&T Program FAQ |
| Senior Citizen Deferral | Older homeowners who may qualify through Oregon Department of Revenue rules. | Remember deferral means taxes are postponed and must be paid later. | Tax Programs |
| Disabled Citizen Deferral | Homeowners receiving qualifying disability benefits and meeting DOR requirements. | Check income, ownership and state program requirements before applying. | Tax Programs |
| Manufactured Home Information | Manufactured home owners with tax, ownership or delinquent-tax questions. | Use Washington County Assessment & Taxation for manufactured home ownership and tax help. | Manufactured Home FAQ |
Important wording: Oregon senior/disabled programs are often deferral programs, not simple “senior exemptions.” A deferral can postpone taxes, but the taxes may need to be paid later under state rules.
Washington County Property Value Appeals
If your issue is the value of the property, the payment office is not the only place to look. Washington County uses the Property Value Appeals Board process for many value disputes. This is about value, not simply whether you like the amount of tax.
- Read your tax statement and compare RMV/AV with your evidence.
- Call appraisal if you have value questions.
- Review Property Value Appeals Board instructions and deadlines.
- Prepare evidence, such as sales, condition issues, appraisal support or property facts.
- File before the applicable deadline for the tax year.
Helpful detail: Washington County appeal guidance says there is no fee for filing an appeal with the Property Value Appeals Board in Washington County. Always verify the current tax-year deadline before filing.
Late, Delinquent and Tax Foreclosure Timeline
Late property tax payments can become more serious over time. Washington County states that real property accounts are delinquent if not paid in full by May 15. If taxes remain unpaid for three years, the County will initiate tax foreclosure proceedings.
- Search your property tax account.
- Confirm which tax years are unpaid.
- Review interest and delinquent balance before paying.
- Check whether the account is still in installment status or delinquent status.
- If a foreclosure or legal deadline is involved, contact the County or a qualified professional quickly.
Urgent warning: Do not ignore delinquent, foreclosure, manufactured home, business personal property or legal notices. Timelines and remedies can be different depending on the property type and tax year.
If Your Mortgage Company Pays Your Taxes
If your lender or escrow company pays your Washington County property taxes, still check the online account record. A lender may request the bill, but you should confirm that payment actually posts before the deadline.
- Search the property tax account after statements are issued.
- Compare the tax bill with your escrow statement.
- Check if the lender requested the bill or has already paid.
- Do not pay personally until you know whether the lender payment is pending.
- Save your escrow statement and Washington County payment-status proof.
If You Just Bought a Property in Washington County
New owners often receive confusing tax information because Oregon property taxes are tied to the tax year, the prior owner, escrow setup, closing credits and mailing address timing. Do not assume the seller credit means the tax bill has already been paid to the County.
- Find your tax account number from closing documents or the online tax portal.
- Compare the current bill with your settlement statement.
- Check whether your lender is responsible for the next payment.
- Confirm the mailing address on the tax account.
- Save the tax statement, closing disclosure, escrow documents and payment proof together.
Mailing Address, Statement and Receipt Problems
A wrong mailing address can cause missed statements, missing notices, delayed refund correspondence and confusion after a sale. If you do not receive the statement, use the online record and contact Assessment & Taxation instead of waiting past the due date.
Statements are mailed by the official deadline, but online records are the safer backup when the due date is close.
Use the official property tax tools to print or save a receipt after payment posts.
If the Oregon Department of Revenue or lender requested the bill, check with your lender before paying personally.
Update mailing information and keep proof of any address-change request.
