Multnomah County Property Tax Guide: Pay, Search, Due Dates & Exemptions
Multnomah County property tax is easier to handle when you verify the property record before making a payment. A missing statement, mortgage-company request, yellow tax bill, old PDF, unpaid prior year, exemption question, or appeal deadline can change what you should do next. This guide explains the process in plain English so you can understand the bill here, then use the official county site only when you are ready to search, pay, file, appeal, or contact DART.
Quick Answer
To manage Multnomah County property tax, search the property on multcoproptax.com by Property ID or address, confirm the correct account, open the Bills tab, review the current statement, payment history, value information and due dates, then pay through an official county-supported option. If the bill is yellow, check with your mortgage company or deferral program before paying yourself.
Important: Do not pay from an old saved bill without checking the live record. Discounts, interest, prior-year balances, payment history and mortgage activity can change what you owe or how your payment should be applied.

Multnomah County Property Tax Due Dates
Property tax statements are mailed before October 25 each year. Payments are due November 15 unless the 15th falls on a weekend or holiday, in which case the due date moves to the next business day. County guidance currently lists property tax payments as due November 15, 2026.

| February 15 installment | Second installment applies if you choose the 1/3 payment route. | Track the date because no discount applies to the 1/3 plan. |

How to Read a Multnomah County Property Tax Statement
The property tax statement is more than a payment notice. It helps you confirm account number, property ID, owner, address, assessed value, tax districts, due date, payment options, discounts, mortgage/deferral requests and appeal information.
| Statement Area | Why It Matters | What To Do |
|---|---|---|
| Account Number / Property ID | This identifies the property tax account. | Use it for search, payment, phone questions and mailed payments. |
| Owner and situs address | Confirms you are viewing the correct property. | Check for ownership, mailing or unit-number mistakes. |
| Tax year and amount due | Shows current-year tax and any amount due. | Compare with payment history before paying. |
| Discount and installment table | Shows how much is due for full, 2/3 or 1/3 payment choices. | Choose a payment path before the deadline. |
| Yellow bill notice | May indicate a mortgage company or deferral program requested tax information. | Check with that payer before making a duplicate payment. |
| Appeal information | Explains deadline and value appeal basics. | Appeal value by December 31 if eligible and supported by evidence. |
Why Did My Multnomah County Property Tax Increase?
Oregon property tax is often misunderstood. The tax bill itself is not capped at 3% per year. Multnomah County explains that the 3% limit applies to Maximum Assessed Value, and tax amounts can increase by more than 3% because of levy code rate changes, loss of compression savings, exception events or a combination of factors.
- Open the county’s “How Your Property Taxes Are Calculated” page.
- Compare Real Market Value, Maximum Assessed Value and Assessed Value.
- Review your Levy Code Area and taxing districts.
- Check for compression changes and bond or special assessment items.
- Use the five-year graph tool to compare value and taxes.
The 3% limit applies to MAV, not automatically to the full tax bill.
Changes in the tax rate for the Levy Code Area can affect the amount due.
Compression can reduce taxes under Oregon constitutional limits, but loss of compression savings can increase a bill.
New construction, changes or other exception events can affect assessed value and taxes.
Multnomah County Property Tax Exemptions and Special Programs
Multnomah County DART Special Programs Group explains that Oregon law provides property tax exemptions for individuals and certain organizations. Some programs are homeowner-focused, while others apply to nonprofit, housing, farm/forest, veteran, surviving spouse or special property situations.
- Open the DART Special Programs Group page.
- Identify whether your question is a homeowner, housing, nonprofit or other program.
- Read the program-specific requirements before applying.
- Prepare proof of ownership, occupancy, disability, veteran status, organizational purpose or income if required.
- Submit application and documentation through the official route listed for that program.
| Program Topic | Who Should Review | Practical Step |
|---|---|---|
| Disabled Veteran Exemption | Disabled veterans who own and live in a Multnomah County home as primary residence. | Review disability certification and honorable discharge documentation rules. |
| Veteran surviving spouse exemption | Surviving spouses who may qualify under Oregon veteran exemption rules. | Check eligibility and documentation before filing. |
| Senior or disabled citizen deferral | Owners using or considering an Oregon deferral program. | If your bill is yellow, confirm whether a deferral program has requested tax information. |
| Nonprofit exemption | Qualifying nonprofit organizations seeking property tax exemption. | File within the official application window and include required documents. |
| Farm or forest deferral | Owners with land that may qualify under farm or forest program rules. | Contact DART farm and forest program support before assuming eligibility. |
Disabled veteran note: County guidance says disabled veterans must own and live in the Multnomah County home as a primary residence, be certified as 40% or more disabled by an approved source, and have received an honorable discharge.
How to Appeal Multnomah County Property Value
You generally cannot appeal only because the tax bill feels too high. The Property Values Appeals Board process focuses on value or qualifying penalty issues. For value appeals, you are asking for a reduction of the property value shown on the statement.
- Wait until the current year property tax statement is available.
- Review Real Market Value and Assessed Value.
- Compare your property with sales, condition issues, photos, appraisals or repair estimates.
- File a separate petition for each account if appealing more than one property.
- Submit the petition by the December 31 deadline unless the deadline moves due to weekend or holiday.
- Include the required filing fee per account.
| Appeal Detail | Official Rule | What To Do |
|---|---|---|
| Deadline | Appeal petitions are due by December 31 for the current tax year value. | Do not wait for payment deadline confusion to pass. |
| Filing fee | $30 per account. | Submit fee with the petition to avoid dismissal risk. |
| Submission method | Appeals are accepted by mail or in person only; email or fax is not accepted. | Mail early or deliver in person with proof. |
| What to appeal | Value appeals challenge value, not simply the tax amount. | Prepare evidence tied to the valuation date. |
Payment warning: Appeal deadlines and tax payment deadlines are separate. Filing an appeal does not automatically stop interest, delinquency or payment requirements.
Mortgage Company, Yellow Bill or Deferral Program
If your property tax bill is yellow, Multnomah County says it means a mortgage company or senior/disabled citizen deferral program requested tax information to pay the bill. This does not mean you should ignore the account. It means you should verify who is responsible before paying yourself.
- Search the property record and open the current tax statement.
- Review payment history and the current amount due.
- Check whether the bill is yellow or whether a lender has requested tax information.
- Compare the record with your mortgage escrow statement.
- If you recently paid off or changed loans, confirm who will pay the tax.
- Do not make a duplicate payment until you understand refund and overpayment handling.
Overpayments, Refunds and Duplicate Payments
Overpayments can happen when an owner and mortgage company both pay, a mailed check posts after an online payment, a prior-year issue is corrected, or an exemption or value decision changes the account. Multnomah County says overpayments from a single party above $10 are automatically refunded, and an overpayment may instead be credited to outstanding property tax liability of the paying party.
- Search the property account and review payment history.
- Compare county records with bank, card, escrow, mail or drop-box proof.
- Check whether the overpayment was from one party or multiple payers.
- Review whether outstanding property tax liability exists.
- Contact DART Customer Service for account-specific refund questions.
Can happen when an online payment is made after a mailed check or bank payment is already moving.
Can happen when the owner pays while the lender or deferral program also pays.
Refund checks and notices can be delayed if the mailing address is wrong.
A value decision, correction or program change can affect final tax liability.
Late, Delinquent or Foreclosure-Related Property Taxes
If taxes are late, interest is charged on past-due amounts. If a property is in foreclosure, the county payment page says to call 503-988-3334 to discuss payment options. For business, manufactured structure, floating property, machinery and equipment, or utility delinquency questions, review the county’s delinquent payment plan guidance.
- Search the property account and identify the earliest unpaid year.
- Review payment history and any interest shown.
- Remember payments may be credited to the earliest year due.
- If foreclosure is involved, call the county foreclosure payment number.
- If business or special property is delinquent, use the county delinquent plan request guidance.
- Keep proof of every payment and every county communication.
Urgent note: If the property involves foreclosure, bankruptcy, probate, estate ownership, tax title, large delinquency or legal deadlines, use official county help and qualified professional advice before relying only on a general guide.
If You Just Bought a Multnomah County Property
New owners often get confused because the property tax year, closing credits, mortgage escrow setup, mailing address and prior owner payment timing can overlap. Do not assume a closing credit means the county tax is already paid.
- Find the Property ID from your closing documents or online search.
- Search the current tax statement on multcoproptax.com.
- Compare the statement with your closing disclosure and escrow setup.
- Check whether a lender or deferral program is expected to pay.
- Update mailing address if ownership or mailing information is wrong.
- Save closing documents, tax statement, payment history and escrow proof together.
Mailing Address, Ownership and Other Property Changes
A wrong mailing address can cause missed tax statements, late notices, refund delays and appeal confusion. If ownership, mailing address or property information is wrong, use the county’s official assessment and taxation change resources.
- Search the property on multcoproptax.com.
- Check owner, mailing address, situs address and Property ID.
- If something is wrong, review the county’s address or ownership change instructions.
- Keep proof of submitted changes and county responses.
- Still check the tax bill online near October even if a change request is pending.
Documents to Keep Before and After Payment
Good records help if you need to prove payment, request help, review a refund, correct an address, appeal value or compare mortgage escrow activity.
Property ID, statement PDF, Bills tab screenshot, payment amount, discount option, due date and mortgage statement.
Receipt, confirmation number, card or bank proof, drop-box check image, mailed postmark proof and payment history screenshot.
Ownership proof, occupancy proof, veteran/disability certification, organization documents or program-specific evidence.
Tax statement, value notice, photos, repair estimates, comparable sales, appraisal reports and the filed petition copy.
