How to Make an Oregon PTE-E Election

Say an architect runs her firm as an S-corp in Portland and it clears $300,000 of Oregon profit. Her household income is deep in the six figures, so the federal deduction for state and local taxes is already gone. She pays Oregon income tax on that profit at rates that top out near 9.9% and gets nothing for it on her federal return. The Oregon PTE-E election is the fix, and it costs her no extra state tax to use. This architect is theoretical, not an EntityIQ client, but the setup is the one I run into most in a high-rate state.

What the Oregon PTE-E tax is

Oregon calls its workaround the Pass-Through Entity Elective Tax, or PTE-E. The legislature created it in Senate Bill 727 in 2021 as a business alternative income tax aimed at the federal SALT cap. When an eligible entity elects, it pays Oregon income tax on its own income, and the owners back that income out on their personal returns so it is not taxed twice at the state level. The Oregon Department of Revenue runs the program and publishes the forms.

The reason any of this exists is the federal cap. The One Big Beautiful Bill Act raised the state and local tax deduction ceiling under IRC §164(b)(6) to $40,400 for 2026, but that larger cap phases back toward $10,000 once modified adjusted gross income passes $505,000. A tax the business pays and deducts never reaches Schedule A, so it sidesteps both the cap and the phaseout. That treatment rests on IRS Notice 2020-75, which confirmed a state income tax imposed on and paid by the entity is deductible in figuring the entity's income, with no cap applied.

The rate is 9% and 9.9%

The PTE-E tax is 9% on the first $250,000 of Oregon distributive proceeds and 9.9% on everything above $250,000. Distributive proceeds means the entity's net income plus dividends, royalties, interest, rents, guaranteed payments, and gains, to the extent they are connected with Oregon sources. That is well above the 3% to 5% many states charge on their pass-through tax, so the deduction it generates is larger. On $300,000 of distributive proceeds, the entity tax comes to $27,450, which is 9% of the first $250,000 plus 9.9% of the last $50,000.

Who can elect, and the partnership trap

A partnership or an S-corp can elect only if all of its owners are individuals, or are pass-through entities owned entirely by individuals subject to Oregon personal income tax under ORS Chapter 316. A grantor trust counts, because the grantor is the one taxed. For an S-corp this is rarely a problem, since federal law under IRC §1361 already bars corporate and partnership shareholders. The trap sits with partnerships. One corporate partner, or a partner that is itself a partnership not owned entirely by individuals, knocks the whole entity out of the election. I check the full ownership chain before I promise a partnership client this deduction.

How to make the election on Form OR-21

You make the election by filing Form OR-21, the Oregon Pass-through Entity Elective Tax Return, for the year. The election is annual, so it is a fresh decision every year rather than a switch you flip once. The return is due by the normal due date, including any valid extension, which for a calendar-year entity means April 15 or October 15 on extension. There is no separate one-page election form to mail ahead of time. Filing the OR-21 and paying the tax is the election.

Estimated payments are not optional

This is where owners get tripped up. A pass-through entity that expects to owe the PTE-E tax has to make quarterly estimated payments, due April 15, June 15, September 15, and January 15 after the year ends, using Form OR-21-V. The required annual payment is 90% of the tax, split across the four installments. Miss them and the entity owes underpayment interest, even though the election itself is not final until you file the return. So start the estimates as soon as the decision looks likely, not after year-end.

The owner side is an add-back plus a refundable credit

Oregon runs the owner mechanics differently from a straight credit state, and this is the part worth slowing down on. Because Oregon taxable income starts from federal income, the entity-level deduction already reduced each owner's Oregon income once. To keep the state whole, Oregon makes each owner add their share of the deducted PTE-E tax back to income with code 167 on Schedule OR-ASC or OR-ASC-NP, then claim a refundable credit for their share of the tax the entity paid with code 900. The add-back and the credit cancel out, so the Oregon result is a wash. The only thing that moves is the federal deduction, which is the entire point.

The math, side by side

Back to the theoretical Portland architect. Her S-corp has $300,000 of Oregon distributive proceeds, and her federal marginal rate is 35%. Her income has already phased the personal SALT cap down to the $10,000 floor, and her property tax uses that up, so Oregon income tax on the firm buys her nothing on Schedule A. The Oregon tax she owes is the same either way. The only figure that moves is the federal deduction.

The swing is about $9,608 a year on one election, and the only thing separating the two columns is whether the Oregon tax sits on the business return or on Schedule A. The state tax is identical. The federal deduction is the whole game, and because Oregon's rate is so high, the dollars at stake are larger than in almost any other state. One note of honesty on the number: shrinking the flow-through income by $27,450 also trims the 20% qualified business income deduction a little, so the real benefit lands just under the headline figure.

The SB 1510 extension and the sunset risk

The PTE-E was built to last only as long as the federal SALT cap gave it a reason to exist. It was first set to expire after 2023, then extended, and Governor Kotek signed Senate Bill 1510 on March 31, 2026, carrying the election through tax years beginning before January 1, 2028. The catch is written into the law: the PTE-E expires early if the federal SALT deduction limit expires or is repealed. That federal cap is scheduled to snap back to $10,000 in 2030, so watch the two timelines together before you build a multi-year plan around this election.

When it is not worth the paperwork

The election is not free. It means a separate Oregon business return, quarterly estimates on the entity's behalf, and an add-back and credit to track on each owner's return. If your income sits under $505,000 and your total state and local taxes come in under the $40,400 cap, the larger federal cap may already capture everything you pay, so the election just adds work. It earns its keep when the Oregon tax on your business profits is large, your income is high enough to shrink the personal cap, or both. With a top rate near 9.9%, that bar is easier to clear in Oregon than in most states.

If you want to see whether an S-corp election makes sense in the first place, the EntityIQ calculator models the self-employment tax side, and our guide on the PTET SALT cap workaround walks through the federal mechanics. For how another high-tax state on the West Coast runs its version, compare the California PTET election.
