Instructions for Form MC-40-NP (Tax Year 2025)

Revised 01/23/2026

Employer Withholding Information

If your employer withheld the Multnomah County tax from your wages, the "Locality name" will be reported in box 20 of your W-2 as "Mult" or "Mult PFA" and the amount will be reported in box 19. To claim your withholding credit, complete Schedule W-2 (refer to the "Schedule W-2 Employer Withholding Summary for Multnomah County PFA Tax" instructions) and submit a copy of your W-2(s) with your return. Each W-2 may consist of multiple pages, and local jurisdiction information might not be reported on page 1 but may be reported on subsequent pages. Certain employers use "Total" or "Total City" in box 20 on page 1 of the W-2 to report the combined amount withheld for both the Metro and Multnomah County jurisdictions. This combined amount is not equivalent to Multnomah County withholding, which will be reported with the locality name "Mult" in box 20 on subsequent pages.

Failure to submit a copy of your W-2(s) or failure to respond to our requests for additional documents to verify W-2 information may mean that your Multnomah County withholding cannot be verified. This may cause delays in your return processing and/or result in the removal of the withholding claim from your return, which will reduce your refund or increase the amount you owe. You will receive a bill for any outstanding amounts due.

Contact your employer to request a corrected W-2 if you believe there are errors on your W-2.

Individuals Required to File a Non-Resident/Part-year Resident (NP) Multnomah County Preschool for All (PFA) Tax Return

Every non-resident or part-year resident of Multnomah County required to file an Oregon income tax return for the taxable year and who reports Multnomah County taxable income over $200,000 using Oregon filing status married filing jointly, head of household or qualifying surviving spouse, or over $125,000 using Oregon filing status single or married filing separately is required to file a Multnomah County NP personal income tax return. You must also file a Multnomah County NP personal income tax return if you file a joint return and you are a full-year resident, but your spouse or domestic partner is a non-resident or part-year resident. 

Residency

You are a non-resident if your permanent home was outside Multnomah County all year. An RV is not considered a permanent home outside of Multnomah County. You are a part-year resident if you moved into or out of Multnomah County during the year. There are special circumstances where a resident is treated as a non-resident and a non-resident is treated as a resident. Multnomah County follows these treatments. More information can be found in Oregon's "Publication 17, Individual Income Tax Guide" at oregon.gov/dor/forms.

• Part-year residents. Multnomah County taxes your income from all sources earned or received while you were a Multnomah County resident. Multnomah County also taxes your income from Multnomah County sources while you were a non-resident.
• Non-residents. Multnomah County taxes income you earned while working in Multnomah County and your income from other Multnomah County sources.

Multnomah County Sourced Income

Multnomah County income includes income shown on your federal return for services performed in Multnomah County. Non-resident telecommuters who work for a Multnomah County employer are taxed only on the income earned from work performed in Multnomah County.

Other Multnomah County sources of income (and losses) include:

• Businesses, partnerships, limited liability companies taxed as partnerships, and S corporations located or doing business in Multnomah County or providing services within Multnomah County boundaries.
• Unemployment insurance benefit received because of a Multnomah County job.
• Severance pay received because of a Multnomah County job.

  • Passed through from an S corporation or partnership doing business in Multnomah County.
• Multnomah County retirement income received while you were a non-resident unless you were domiciled within Multnomah County.

Payment Deadline

The payment deadline for this return is April 15, 2026.

Filing Deadline

The filing deadline for this return is April 15, 2026.

Extensions

Multnomah County does not allow an extension of time to pay your tax. The submission of an extension payment by the original return due date provides an automatic six-month filing extension. If you do not have a tax balance due but would like to file an extension, your federal and/or state extension will serve as your extension. When filing your return on the extended due date, check the "Extension Filed" box on the return. If no extension payment was made, please attach a copy of your federal extension or verification of your Oregon extension payment with your return.

Amended Returns

The Revenue Division does not have a separate form for amended tax returns. To amend your 2025 MC-40-NP, use the form for the tax year being amended and check the "Amended Return" box. If the address for the year you are amending has changed, use your current mailing address and check the "Mailing Address Change" box.

Fill in all amounts on your amended return, even if they are the same as originally filed. If you are amending to make a change to additions, subtractions, or credits, include detail of all items and amounts as well as any carryovers. Please include a statement explaining what changed from the original return. 

If you change taxable income by filing an original or amended federal or Oregon income tax return, you must file an amended Form MC-40-NP within 60 days of when the original or amended federal or Oregon income tax return is filed. Include a copy of your original or amended federal or Oregon income tax return with your amended Form MC-40-NP and explain the adjustments made.

On the prepayments line of your amended Form MC-40-NP, enter the net tax as reflected on the original return or as previously adjusted. Do not include any penalty or interest portions of payments already made.

Penalty Calculation

You may be subject to penalties for underpaying your tax liability, filing a late personal income tax return, and/or paying your income tax liability after the original due date of the return. 

Although there is a late penalty for both failing to file a personal income tax return by the due date and failing to pay the tax by the original due date of the return, only one of these late penalties will be applied, even if there is a failure of both requirements.

Late penalties will also be applied if an extension has been requested and the return is filed after the extension due date.

For the purposes of penalty calculations, unpaid tax is your tax liability reduced by any payment of tax made before the original due date and any credit against tax that is claimed on the return.

Underpayment Penalty

You may be subject to a penalty for underpaying your tax liability if, by the original due date of the return, timely payments are not made which are either:

• At least 90% of the total tax balance due, or
• 100% of the prior year's tax liability paid by the original due date.

If you did not satisfy either requirement, you will be charged an underpayment penalty of 5% of the unpaid tax, but not less than $5.

Late Filing Penalty

If you do not file your 2025 Form MC-40-NP by the original due date, file an extension with the Revenue Division by the original due date, or include a copy of your federal extension with your return when you file by the extended due date, the following late filing penalties will be applied:

• 5% of the amount of the unpaid tax 
• An additional penalty of 100% of the unpaid tax of all tax years if the failure to file is for three or more consecutive tax years.

No late filing penalty is due if a timely extension is filed with the Revenue Division and a 2025 Form MC-40-NP is filed by the extended due date, or a copy of the federal extension is included with the return and the ‘Extension Filed' box is checked.

Late Payment Penalty

Your 2025 income tax must be paid by April 15, 2026, even if you requested an extension to file your personal income tax return. If you do not pay your tax by the original due date, the following late payment penalties will be applied:

• 5% of the amount of the unpaid tax 
• An additional penalty of 100% of the unpaid tax of all tax years if the failure to pay is for three or more consecutive tax years.

Interest Calculation

Calculate your interest from the original due date to the 15th day of the month following the date of the payment. The interest rate to use can be found in our Tax Administration Policy – Personal Income Tax Interest Rates on Tax Due and Refunds.

Quarterly Underpayment Interest

Quarterly underpayment interest will be due if estimated payments were required and were underpaid. Estimated payments can be made through quarterly estimated payments, employer-provided withholding from a filer's wages, or a combination of both. Calculate your quarterly underpayment interest at the rate in effect for the tax year from the due date of each quarterly estimated payment to the original due date of the tax return to which the estimated payments apply. The amount of underpayment is determined by comparing the 90% of the current total tax liability amount to quarterly estimated payments made prior to the original due date of the tax return. 

There is no interest on underpayment of quarterly estimated payments if:

• The total tax liability of the prior tax year was less than $1,000.
• An amount equal to at least 90% of the total tax liability for the current tax year was paid in accordance with Section 11.548; or
• An amount equal to at least 100% of the prior year's total tax liability was paid in accordance with Section 11.548.

Schedule INC for Multnomah County PFA Tax

Use this schedule to calculate your Multnomah County taxable income reported on line 1 in Part I of the return and your Multnomah County allowable deductions reported on line 3 in Part I of the return.

Lines 1 through 29 of Schedule INC consist of two columns. The amounts reported on the federal column (F) correspond to your federal adjusted gross income (AGI), additions, and subtractions. The amounts reported on the Multnomah County column (M) correspond your income from all sources earned or received while you were a Multnomah County resident and your income from Multnomah County sources while you were a non-resident, and includes Multnomah County adjustments, additions, and subtractions. 

The sum of your Multnomah County column will determine your Multnomah County taxable income and will be reported on line 1 of Part I of the return. 

Your Multnomah County total divided by your federal total will determine your Multnomah County percentage. The deductions allowed on your Oregon return multiplied by your Multnomah County percentage, plus your charitable art donation if claimed on your Oregon return, will determine your total allowed Multnomah County deduction and will be reported on line 3 of Part I of the return.

For lines 1F through 20F of the federal column, you will enter the amounts reported on your federal return for the corresponding line items. If you filed Form 1040 or 1040-SR, these will be the amounts on lines 1 through 11b and Schedule 1, lines 1 through 22.

In the Multnomah County column, you will report the amounts from the corresponding federal line that are taxed by Multnomah County. For non-residents, Multnomah County taxes only your income from Multnomah County sources. For part-year residents, Multnomah County taxes your income from all sources earned or received while you were a Multnomah County resident and also taxes your income from Multnomah County sources while you were a non-resident. For full-year residents, Multnomah County taxes your income from all sources. If you are a full-year resident filing jointly with a spouse who has a part-time resident or non-resident residency status on Form MC-40-NP, all of your income in the federal column must be included in the Multnomah County column. For more information on how to determine your Multnomah County-source income, refer to Multnomah County Sourced Income in the General Information section.

Schedule PTI – Previously Taxed Income Modification for Multnomah County PFA Tax

Use this schedule to determine the amount of previously taxed income modification to report for pass-through income/loss that was already subject to the Multnomah County Business Income Tax (MCBIT). This schedule must be completed to determine the value for line 2 in Part I of the return. If your pass-through income was not subject to tax under the MCBIT for any reason, you are not eligible to claim a previously taxed income modification.

Income from Pass-Through Entity Subject to MCBIT

You are allowed a deduction from personal taxable income for previously taxed income derived from a pass-through entity (PTE) subject to the MCBIT. To take this deduction, you must have documentation from the PTE showing your share of income that was subject to tax on the business's MCBIT return. The deduction is limited to the amount of pass-through income, from the entity that paid the MCBIT, that is included in your federal Form 1040.

For more information related to this modification, please read our Tax Administration Policy – Deduction for Previously Taxed Income Received from a Pass-Through Entity.

Losses from Pass-Through Entity Subject to MCBIT

Net operating losses generated in the current tax year at the PTE level are allowed to be claimed at the individual level to the extent that the loss is allowed on the federal and Oregon return. A pass-through loss cannot exceed the amount of pass-through loss included in Multnomah County taxable income and cannot reduce your Multnomah County taxable income to an amount below zero.

If you claimed a net operating loss deduction on your federal Form 1040 that was from a carryforward of a net operating loss from a year that the PTE was subject to the MCBIT, the deduction is disallowed for purposes of the Multnomah County PFA Personal Income Tax and must be added back to your Multnomah County taxable income as a pass-through modification. Include a statement explaining the adjustment.

For more information related to pass-through losses, please read our Tax Administration Policy – Net Operating Losses and Net Operating Loss Deduction from Pass-Through Entities.

Schedule PTI Instructions

Schedule ASC For Multnomah County PFA Tax

If you file an Oregon return and claim additional income adjustments, additions, subtractions, and modification on Schedule OR-ASC or Schedule OR-ASC-NP, use Schedule ASC to make the corresponding applicable Multnomah County adjustments, additions, subtractions, and modifications on your Multnomah County return. Any adjustment, addition, subtraction, or modification reported on Schedule ASC must be identified with the same numerical code that was used to claim the corresponding adjustment, addition, subtraction, or modification on the Schedule OR-ASC or Schedule OR-ASC-NP. As with the Oregon schedule, each code may only be used one time on the Schedule ASC.

If any adjustments, additions, subtractions, or modifications are claimed on Schedule ASC, include the schedule when filing your Form MC-40-NP, and also include a copy of your Schedule OR-ASC or Schedule OR-ASC-NP with your supporting tax pages. If you require more lines than are available on Schedule ASC, use additional copies of the schedule as needed to report any additional information and be sure to include all pages with your return. Enter the totals of all line items of each section of each page of Schedule ASC on Schedule INC. If your Schedule ASC has more than one page, be sure that you submit all pages with your return.

When determining the federal amount to report on the Schedule ASC, enter the amount that would be reported on your Multnomah County return if you were a full-year resident of Multnomah County.

When determining the Multnomah County amount to report on the Schedule ASC, calculate the portion of the Oregon amount from Schedule OR-ASC or Schedule OR-ASC-NP that applies to Multnomah County for the portion of the year you were a Multnomah County resident and the portion of the year you were a non-resident with Multnomah County sourced income. For more details about codes and adjustments, additions, subtractions, and modifications reported on Schedule OR-ASC and Schedule OR-ASC-NP, refer to Oregon's Publication OR-17.
