Individual tax returns in Portland, prepared by a CPA

Individual tax returns in Portland start with where you live

Your address on 12/31 is not the only thing that counts. Oregon looks at whether you lived in the state for the whole year, part of it, or not at all. Full year residents file Form OR-40, people who moved in or out file Form OR-40-P, and people who lived elsewhere but earned Oregon income file Form OR-40-N.

Inside the Portland area, the local layer depends on even smaller lines on the map. The Arts Tax applies to City of Portland residents. The Metro Supportive Housing Services tax applies to residents of the Metro boundary. The Preschool for All tax applies to Multnomah County residents. Someone in Beaverton and someone in Northeast Portland can earn the same salary and still end up with a different set of returns.

A CPA who prepares returns for Portland area clients every season will ask where you lived and worked month by month, then match that to the right forms. Getting this wrong usually means a letter later, so it is worth settling before you file.

Wages, stock pay and the Metro and county taxes

Many people in Hillsboro, Beaverton and downtown Portland are paid partly in company stock through restricted stock units (RSUs, shares that vest over time) or an employee stock purchase plan (ESPP). The income can show up on your W-2 and the later sale on a brokerage Form 1099-B. The IRS instructions for Form 8949 note that for stock options granted after 2013, the basis shown on Form 1099-B will not reflect the amount you already included in income, so the basis has to be increased to avoid paying tax twice. Your CPA checks RSU and ESPP sales against your W-2 and pay records in the same careful way.

Higher income also brings in the local taxes. For tax year 2025, the Metro SHS tax is 1 percent of Oregon taxable income above $125,000 for single filers or $200,000 for joint filers, and those thresholds rise to $128,000 and $205,000 for tax year 2026. The Multnomah County PFA tax is 1.5 percent above $125,000 single or $200,000 joint, with another 1.5 percent above $250,000 single or $400,000 joint.

Employers with a Metro or Multnomah County location must withhold these taxes for employees who work in those areas and earn $200,000 or more in a calendar year, although employees can opt in or out of withholding. If your employer did not withhold, or you earned income from more than one source, you may owe a balance on the local returns even when your federal and Oregon returns look settled.

The Oregon kicker and other state items

In some years Oregon returns surplus revenue to taxpayers through a credit known as the kicker. For tax year 2025, the kicker is claimed on the 2025 return and equals 9.863 percent of your 2024 Oregon personal income tax liability. To qualify, you must have filed a 2024 return, had a 2024 liability, and file a 2025 return. You can also choose to donate it to the Oregon State School Fund.

Oregon also expects estimated payments during the year from people who will owe at least $1,000 after credits and withholding. That catches many retirees, landlords and people with large stock sales, not just the self employed.

Your CPA will also look at items that are easy to overlook on a state return, such as Oregon tax withheld by a second employer or a payment you made with last year's extension.

Life changes that make a return harder

A single life event can change your filing status, add a new form or bring a local tax into play for the first time. If more than one happened in the same year, a CPA review is usually worth it, because the items affect each other and are easy to miss when you look at them one at a time.

A simple W-2 return can turn into something more involved in a single year. These are the events that most often lead Portland area clients to look for a CPA instead of filing on their own:

• Moving into or out of Oregon, which brings part year returns
• Starting freelance or gig work reported on a 1099-NEC
• Buying a first home or renting out a former one
• Selling stock, a house or a rental property
• Getting married, divorced or having a child
• Taking money out of a retirement account
• Working in Oregon while living in Washington

Deadlines and extensions for individual returns

Individual returns are generally due 4/15, shifted to the next business day when that date falls on a weekend or legal holiday. Tax year 2025 federal and Oregon returns were due 4/15/2026, as were the Arts Tax, SHS and PFA returns.

Form 4868 extends the federal filing date by up to six months, and Oregon accepts that federal extension. For tax year 2025 the extended date was 10/15/2026. Payment is still due by the original deadline. One more date is worth knowing: contributions to a traditional or Roth IRA for a tax year can be made up to the filing deadline for that year, not including extensions, so you cannot use an extension to buy more time for an IRA deposit.

If you expect a refund, there is less pressure, but filing on time still matters. A refund for withholding or estimated payments must be claimed within 3 years of the return's due date, after which it can be lost.

Living in Washington and working in Portland

Many people who live in Vancouver and Camas cross the Columbia for work, and their returns follow their own pattern. A Vancouver or Camas resident who earns Oregon income files Form OR-40-N, the Oregon nonresident return, and reports the Oregon part of their income there.

Oregon's statewide transit tax is withheld from the wages of nonresidents for work done in Oregon, so it will show on your pay stub even though you live across the river. The Metro SHS and Multnomah County PFA taxes can also reach nonresidents who earn income inside those areas, depending on the amount. Your CPA will ask where you actually did your work during the year, including any days you worked from home, so the Oregon share of your wages is reported correctly.

If your employer withheld the wrong state's tax, or none at all, a CPA can sort out what you owe and help you set the right withholding for next year.

Keeping your records and getting a quote

The IRS general rule is to keep tax records for three years, although some situations call for longer. Your CPA will give you a complete set of filed returns for your files, which also helps if you apply for a mortgage or need to prove income later.

Tell us what you need and a licensed CPA who works with people like you gets in touch with a clear, fixed quote. Mention anything unusual up front, such as a move, stock sales or rental income, so the quote reflects the real work involved.
