Portland Oregon Tax Guide 2026: OR 9.9%, Multnomah County Income Tax & No Sales Tax

KEY INSIGHT

Portland has one of the highest combined income tax burdens of any major US city. Oregon state income tax tops at 9.9% (on income above $125,000 single / $250,000 married). Multnomah County adds a Preschool for All income tax (1.5% above $125K single, 3% above $250K single). The Metro district adds another 1% on income above $125,000 for Supportive Housing Services. A high-income Portland resident can face a combined state+county+metro income tax of 13.4% — similar to California. The compensating factor: Oregon has NO sales tax. Portland also has a $35/year arts tax on residents.

Key Facts

Oregon State Income Tax — Up to 9.9%

Oregon state income tax brackets (2026, approximate): 4.75% on first $10,200 single / $20,400 MFJ; 6.75% on $10,200–$25,500 single / $20,400–$51,000 MFJ; 8.75% on $25,500–$125,000 single / $51,000–$250,000 MFJ; 9.9% on income above $125,000 single / $250,000 MFJ. Oregon's 9.9% top rate applies broadly — kicking in at $125,000 for single filers (lower threshold than California's 13.3% which starts at $1M+). Oregon standard deduction: $2,420 single / $4,840 MFJ (2026, adjusted for inflation). Oregon personal exemption credit: $236/exemption. Oregon does not have a capital gains preference — long-term capital gains taxed at ordinary income rates up to 9.9%.

Multnomah County Preschool for All Income Tax (PFA)

Multnomah County's Preschool for All tax was approved by voters in 2020 and took effect January 1, 2021. Rates (2026): 1.5% on taxable income between $125,000–$250,000 (single); 3% on taxable income above $250,000 (single). For joint filers: 1.5% on $200,000–$400,000; 3% on income above $400,000. The tax applies to: Multnomah County residents (including Portland, Gresham, Troutdale); non-residents with Multnomah County-source income. Administration: self-assessed via annual return filed with Revenue Division. Employer withholding: employers can voluntarily withhold — most larger employers do. Applies to: wages, self-employment income, and pass-through income from businesses. Does not apply to: retirement income from public pension plans (PERS), Social Security.

Metro Supportive Housing Services Income Tax (SHS)

The Metro district (greater Portland region including parts of Washington and Clackamas counties as well as Multnomah County) enacted a 1% income tax on taxable income above $125,000 single / $200,000 MFJ for Supportive Housing Services, effective January 1, 2021. Rate: 1% flat on all taxable income above the threshold. No upper limit. Applies to Metro district residents and non-residents with Metro-source income. Filed with Revenue Division. Stacks directly on top of both Oregon state income tax and Multnomah County PFA. A Portland resident earning $300,000 pays: 9.9% OR state + 3% Multnomah PFA + 1% Metro SHS = 13.9% combined state/local income tax rate on the top dollar (before federal).

Oregon Has No Sales Tax — The Key Offset

Oregon is one of only five states with no state sales tax (alongside New Hampshire, Montana, Alaska, and Delaware). Portland and all Oregon municipalities cannot impose sales tax — the state constitution prohibits it. Practical impact: every purchase in Oregon — groceries, clothing, electronics, cars, furniture, services — is free from sales tax. For residents who spend heavily, the lack of sales tax partially offsets the high income tax. Example: on $100,000 in annual spending, a California resident might pay $8,000+ in sales tax (8%+ combined rate); an Oregon resident pays $0. For high-income earners with modest spending relative to income, the sales tax offset is limited — the income tax burden at high incomes is not fully offset by zero sales tax savings.

Portland Arts Tax — $35/Resident/Year

Portland imposes a small arts tax on residents: $35/year per adult resident aged 18+ with annual income above the federal poverty level. The arts tax funds arts education programs in Portland public schools. It is a flat per-person tax — not income-based above the poverty threshold. Extremely low-income residents are exempt. Filing: due April 15 with an annual return to Revenue Division. Enforcement: the city has the authority to garnish wages and intercept state tax refunds for non-payers. While the dollar amount is trivial, the arts tax is notable as one of the few per-head income taxes in the US.

Oregon Corporate Activity Tax (CAT) — For Business Owners

Oregon's Corporate Activity Tax (CAT), effective 2020, applies to businesses with more than $1 million in Oregon commercial activity. Rate: $250 plus 0.57% on Oregon commercial activity exceeding $1 million. Not an income tax — applies to gross receipts (commercial activity), not net profit. Pass-through businesses (S-corps, LLCs, partnerships) are subject if their Oregon commercial activity exceeds $1M. Self-employed Portland professionals with high client billing may reach the CAT threshold. Key: the CAT is a cost of doing business in Oregon, not deductible for Oregon income tax purposes. Planning implication: business owners approaching $1M in Oregon commercial activity face a new tax layer not present in most peer states.

Introduction

Portland occupies an unusual position in US tax comparisons: among the highest income tax burdens of any major city, but with zero sales tax statewide. The income tax picture has become significantly more complex in recent years with the addition of Multnomah County's Preschool for All tax (2021) and the Metro district's Supportive Housing Services tax (2021) — both new income taxes layered on top of Oregon's already-high state rates. This guide explains all four layers of Portland income taxation (federal, Oregon state, Multnomah County, Metro), the no-sales-tax advantage, and the specific tax considerations for Portland's technology, healthcare, and professional workforce.

Section 01

Understanding Portland's Three-Layer Local Income Tax

Portland is unusual in having three distinct local income taxes stacked on top of state income tax. This creates complexity that most tax software handles poorly without local knowledge.

How All Three Interact

For a single Portland resident earning $300,000 in wages (all sources in Multnomah County / Metro district): Oregon state income tax at 9.9% on income above $125,000 — approximately $20,625 on the top $208,750 above $125K. Multnomah PFA at 3% on income above $250,000 — $1,500 on the top $50,000. Metro SHS at 1% on income above $125,000 — $1,750 on the $175,000 above $125K. Total state+local income tax on $300,000: approximately $34,000–$35,000 (11.3–11.7% effective rate on total income). Federal income tax on top of this adds approximately $73,000–$75,000 (24.3–25% effective). All-in effective rate (federal+state+local): approximately 36%.

Filing Requirements for Portland Locals

Three separate filings may be required: Oregon Form OR-40 (state return, due April 15); Multnomah County PFA return (Revenue Division, due April 15); Metro SHS return (Revenue Division, due April 15). Revenue Division handles both the county and Metro filings — they share a portal. Estimated payments: required quarterly for each tax if you expect to owe more than $1,000. For W-2 employees, employer withholding should cover most of the state and federal liability — but employer withholding for PFA and SHS is voluntary, so many employees receive unexpected bills.

Non-Residents Working in Portland

If you live in Washington state (no income tax) but work in Portland, you owe: Oregon non-resident income tax on Oregon-source wages (up to 9.9%); Multnomah County PFA on Multnomah County-source income (if above thresholds); Metro SHS on Metro district-source income (if above thresholds). The three-layer burden on non-residents commuting from Washington (Clark County / Vancouver WA) is a real consideration — many Portland metro workers have made the deliberate choice to live in Vancouver, WA (no state income tax, no county/metro taxes) while working in Portland. The commute across the Columbia River is common specifically for this reason.

FAQ

Frequently Asked Questions

I live in Vancouver, WA and work in Portland — what taxes do I owe?

As a Washington resident working in Portland, you owe Oregon non-resident income tax on wages earned in Oregon (Oregon taxes non-residents on Oregon-source income). You'd file Form OR-40-N. You also likely owe the Multnomah County PFA and Metro SHS taxes if your Oregon-source income exceeds the thresholds. Washington residents do not owe Washington state income tax (WA has none). You do NOT owe Oregon tax on investment income (dividends, interest, capital gains) earned from non-Oregon sources — only on Oregon-source wages. Many Vancouver WA residents specifically choose to live there to avoid Oregon state income tax on passive income and retirement income while still working in Portland.

Does Portland's no-sales-tax advantage actually offset the high income tax?

For very high earners, generally no — the offset is limited. A $500,000 income earner paying 13%+ in state/county/metro income taxes saves perhaps $5,000–$10,000 in sales tax on $100,000 of spending. The income tax cost dwarfs the sales tax saving. For middle-income earners ($80,000–$150,000), the calculation is more balanced — the 8.75% Oregon rate on most income is comparable to California's 9.3%, but without sales tax, the overall burden may be similar. For retirees with fixed incomes who spend heavily, the no-sales-tax benefit is more meaningful. Oregon is also sales-tax-free on groceries, medications, and clothing (which many states exempt anyway), limiting the marginal benefit for low-income households.

Are there ways to reduce exposure to Portland's Multnomah and Metro income taxes?

Legitimate planning strategies include: Retirement contributions — maximise 401(k), IRA, and HSA contributions; these reduce taxable income that triggers PFA and SHS; Capital gains timing — long-term capital gains are subject to full Oregon rates; consider harvesting losses or timing realisation in lower-income years; Qualified opportunity zone investments — Oregon conforms to federal QOZ tax deferral, which can defer recognition of capital gains. Oregon does not offer a capital gains exclusion like some states. Relocation: some high-earners have moved their residency outside Multnomah County (e.g., to Washington County or Clackamas County suburbs) to avoid the PFA while remaining in the Metro district for SHS. Moving to Vancouver, WA eliminates Oregon state tax entirely on non-OR-source income. Consult a CPA for your specific situation.

How does Oregon tax capital gains compared to other states?

Oregon taxes long-term capital gains as ordinary income at the state income tax rate (up to 9.9%). There is no preferential capital gains rate in Oregon — unlike the federal system (0/15/20%) or states like Wisconsin that offer partial exclusions. This means Oregon residents pay up to 9.9% state capital gains tax on top of up to 23.8% federal (20% + 3.8% NIIT). Combined federal+state capital gains tax for a high-income Oregon investor: up to 33.7%. This compares unfavourably to Texas, Florida, and other no-income-tax states. Portland residents with substantial investment portfolios often consult about domicile planning — establishing residency in a no-tax state before selling appreciated assets.
