At InterMap, searches can be done using a situs address, account number or Tax Lot ID. If the first search does not work, simplify the address, remove punctuation, or try the account/R number from your tax statement.

- Use InterMap when you need parcel, map, value, sales or improvement information.
- Search by situs address first if you do not know the account number.
- Use Account Number/R number or Tax Lot ID for a more exact match.

How to Look Up or Print a Washington County Property Tax Statement
If you need the tax bill amount, payment options, delinquent balance or a printable statement, use the tax statement route rather than a map-only parcel search.
Washington County says all property owners receive a tax statement. If you do not receive one by November 1, the county directs owners to call Tax Collections or use the county tax lookup route to view or print a copy.
- Go to the Washington County property tax statement lookup route.
- Search using the property tax account number when possible.
- Check the payment options area on the front of the statement.
- Look for current, prior-year or delinquent amounts before paying.
- Print or save the statement and payment confirmation for your records.
Missing statement warning: Not receiving a paper statement does not remove the owner’s responsibility to pay. Use the lookup tool or call Property Tax Collections if the statement does not arrive by November 1.
Washington County Property Tax Due Dates and Installments
Washington County property taxes follow Oregon’s common installment schedule. Tax statements are usually mailed in October, and payment options begin with the November due date.
If a due date falls on a weekend or holiday, the actual date may move to the next business day. Always check the current tax statement before making a deadline decision.
| Date or Period | What It Usually Means | What to Do |
|---|---|---|
| July 1 | First day of the fiscal tax year. | Use this as the start of the tax-year timeline, not the payment due date. |
| Early October | Tax roll certification period. | Watch for updated statement and value information. |
| By October 25 | Tax statement mailing deadline. | Expect statement delivery before November, then verify online if needed. |
| November 15 | First installment due date and full-payment discount deadline in many years. | Pay full, two-thirds or one-third according to statement options. |
| February 15 | Second installment due date when paying in thirds. | Confirm prior payment posted before paying the next installment. |
| May 15 | Third installment due date and final real-property payment deadline. | Pay remaining balance before delinquency and interest issues grow. |
| December 31 | General Property Value Appeals Board filing deadline. | File a value appeal before this date if you disagree with the current-year value. |
How to Pay Washington County Property Taxes Safely
Washington County accepts property tax payments online, by phone, by mail, in person, by drop box and through bank bill pay. The safest payment method depends on your deadline, confirmation needs and fee tolerance.
Online and phone payments require the property tax account number. Washington County says online payment steps must be completed fully, and taxpayers should print or save the final confirmation page.

Yellow vs Green Washington County Tax Statements
Statement color matters because it can signal who intends to pay. A yellow statement generally indicates that a mortgage company or the Oregon Department of Revenue requested the statement and intends to pay.
A green statement generally means the owner is responsible for payment. Even if a mortgage company is involved, property owners should confirm payment responsibility to avoid double payments or missed payments.
| Statement Color | Plain Meaning | Owner Action |
|---|---|---|
| Yellow | A mortgage company or Oregon Department of Revenue requested a copy and may intend to pay. | Confirm with your mortgage company or deferral program before ignoring the bill. |
| Green | The owner is responsible for paying the tax statement. | Choose a payment method and save proof before the due date. |
| Recently refinanced | Escrow responsibility may have changed. | Contact the mortgage company and verify who will pay. |
| Recently bought or sold | Ownership updates may not have been complete when bills printed. | Contact Tax Collections if the statement went to the wrong owner. |
Washington County Property Values: RMV, MAV and Assessed Value
Oregon property tax records often show more than one value. Real Market Value, Maximum Assessed Value and Assessed Value can differ, so do not assume the highest number is the amount used to calculate taxes.
Washington County explains that Oregon law requires the assessor to value property at 100 percent of real market value. For many accounts, maximum assessed value can increase by 3 percent per year, unless exceptions apply.
| Value Term | What It Means | Why It Matters |
|---|---|---|
| Real Market Value | The county’s estimate of market value. | This is often the number challenged in a value appeal. |
| Maximum Assessed Value | A limit used under Oregon’s property tax system. | It can grow differently than market value. |
| Assessed Value | The value used for taxation after Oregon value rules are applied. | This may be lower than real market value. |
| Changed Property Ratio | A factor used for new construction or changed property in some situations. | New improvements may affect value differently than existing property. |
How to Appeal a Washington County Property Value
If you disagree with the property value on your tax statement, you may be able to file with the Property Value Appeals Board. The board hears value appeals, not complaints about the amount of tax you pay.
Washington County says petitions are filed between late October, when statements are mailed, and December 31. If December 31 falls on a weekend or holiday, the deadline moves to the next business day.
- Review the real market, maximum assessed and assessed values on your statement.
- Decide what value you believe is correct for the current tax year.
- Gather evidence such as sales, appraisals, condition issues, income records or comparable properties.
- File the PVAB petition by the deadline.
- Choose whether to appear at the hearing or let the board decide from written evidence.
Appeal warning: PVAB generally reviews the current year. Prior-year issues, industrial property appraised by Oregon Department of Revenue, or court-level appeals may follow different rules.
Evidence Checklist for a Washington County Value Appeal
A value appeal is stronger when your evidence explains why the county value is wrong. Do not rely only on “my taxes are too high.” The board needs evidence tied to value.
| Evidence Type | Best For | How to Use It |
|---|---|---|
| Recent comparable sales | Residential or land value disputes. | Use similar location, size, age, condition and sale timing. |
| Independent appraisal | Higher-value or complex disputes. | Use an appraisal close to the assessment date. |
| Photos of condition problems | Damage, deferred maintenance or construction issues. | Date photos and explain the value impact. |
| Repair bids or inspection report | Showing cost to cure defects. | Connect the repair cost to your requested value. |
| Income and expense records | Rental, commercial or income-producing property. | Use clear, organized current-year support. |
| Business personal property records | Equipment, furniture, fixtures or business assets. | Use asset lists, depreciation schedules and disposal records. |
Business Personal Property Tax Search and Return Issues
Nearly all businesses operating in Oregon may need to file a business personal property return and pay taxes on furniture, fixtures, equipment and other taxable business assets.
If a business account, return, value, penalty or asset listing looks wrong, use the Business Personal Property Assessment route before filing an appeal or making assumptions from a real-property record.
- Confirm whether the business had taxable assets in Washington County.
- Review the return, asset list, value and penalty information.
- Check whether the issue is a filing issue, value issue or payment issue.
- Use PVAB or Tax Court routes only when the official appeal rules apply.
Ownership, Mailing Address and Sold Property Problems
Property tax records may not update immediately after a sale, refinance, divorce, trust transfer or probate event. If you receive a statement for a property you sold, the bill may have printed before the ownership update was complete.
For legal ownership disputes, contact a title company or attorney. For county record updates, use Washington County Assessment & Taxation or Cartography guidance.
Search the account, confirm mailing address and check whether escrow or the prior owner received the statement.
Contact Tax Collections if the statement still shows you and a new bill may need to be generated.
Use the official statement or county process to update mailing information.
This can happen when a tax lot is split by taxing boundaries or a manufactured structure is separate from land.
Delinquent Washington County Property Taxes
Washington County states that real property accounts are delinquent if not paid in full by May 15. Delinquent taxes may be included in the payment options on the front of the statement.
Interest and foreclosure timelines can become serious. If you have prior-year taxes, confirm the payoff amount with Tax Collections before making partial or duplicate payments.
| Issue | What It Means | What to Do |
|---|---|---|
| Past due balance | Older taxes may be included in the payment options. | Call Tax Collections if you are unsure which amount pays the account current. |
| Interest | Past due amounts accrue interest after deadlines. | Confirm total before sending payment. |
| Real property foreclosure risk | After several years unpaid, tax foreclosure proceedings may begin. | Do not ignore notices; contact the county quickly. |
| Business personal property collection | Delinquent BPP can lead to collection action. | Resolve return, penalty and payment questions promptly. |
Common Washington County Property Tax Search Mistakes
Most property tax search problems come from using the wrong tool, searching the wrong identifier, or confusing value records with payment records.
Names can be abbreviated, outdated or listed differently after a sale or trust transfer.
InterMap helps with parcel research, but payment details belong to the tax statement route.
A yellow statement may mean a mortgage company or DOR requested a copy, but you should still confirm payment responsibility.
Use the property tax account number so payment posts to the correct account.
Value appeals generally must be filed by December 31 for the current tax year.
Debit and credit card convenience fees can be significant on large tax bills.
