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 $128,000 (2026, single) for Supportive Housing Services. A high-income Portland resident can face a combined state+county+metro income tax of 13.9% — similar to California. The compensating factor: Oregon has NO sales tax. Portland also has a $50/year arts tax on residents (2026).

Key Facts

Oregon State Income Tax — Up to 9.9%
Oregon state income tax brackets (2026, approximate): 4.75% on first $4,550 single / $9,100 MFJ; 6.75% on $4,550–$11,400 single / $9,100–$22,800 MFJ; 8.75% on $11,400–$125,000 single / $22,800–$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: $2,910 single / $5,820 MFJ (2026, adjusted for inflation). Oregon personal exemption credit: $263/exemption (2026); not available if federal AGI is above $100,000 (single). 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 must withhold from employees earning over $200,000 a year (employees can opt out or opt in to a different amount using the Metro/MultCo opt form). Applies to: wages, self-employment income, and pass-through income from businesses.
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 $128,000 single / $205,000 MFJ (2026 thresholds) 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). Oregon has no general state or local sales tax. 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 — $50/Resident/Year
Portland imposes a small arts tax on residents: $50 per person for 2026 ($100 for married filing jointly), owed by residents aged 18+ who lived in Portland more than 30 days and have Oregon taxable income of at least $20,000 (single) or $40,000 (joint, head of household, qualifying surviving spouse). The arts tax funds arts education programs in Portland public schools. It is a flat per-person tax once the income threshold is met; residents below the thresholds are exempt. Due at the same time as your federal return (generally April 15). Late-payment penalties apply ($15 after the deadline, plus $20 more if still unpaid after six months). 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 taxable commercial activity exceeding $1 million (commercial activity is reduced by a subtraction for cost inputs or labor). 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. 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

Portland's Three-Layer Income Tax: State, County, Metro

Portland-area residents can face two local income taxes (Multnomah County PFA and Metro SHS) stacked on top of Oregon 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), using Oregon taxable income of about $297,090 (wages less the $2,910 standard deduction; the federal tax subtraction is fully phased out at this income) and assuming the local taxes are computed on that same base: Oregon state income tax is approximately $27,655. Multnomah PFA at 1.5% above $125,000 plus a further 1.5% above $250,000 is approximately $3,288. Metro SHS at 1% above the 2026 threshold of $128,000 is approximately $1,691. Total state+local income tax on $300,000: approximately $32,600 (about 10.9% of gross). Federal income tax on top of this adds approximately $68,100 (about 22.7%). All-in effective rate (federal+state+local, before payroll taxes): approximately 33.6%.

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: underpayment interest applies to PFA and SHS when liability exceeds $5,000 from tax year 2026 (it was $1,000 for 2022-2025). For W-2 employees, employer withholding should cover most of the state and federal liability. Employers must withhold PFA and SHS only for employees earning over $200,000 (and others can opt in), so employees below that level who owe these taxes can 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 facing a 13.9% top combined state/county/metro marginal rate 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.
