Oklahoma guide
The Oklahoma pass-through entity tax election,
and who it actually helps.
Since 2019, an Oklahoma S corporation or partnership can choose to pay the state income tax on its owners’ behalf, which moves that tax out from under the federal cap on state and local deductions. For some owners it is the largest tax decision of the year. For others it changes nothing. Here is how to tell which you are, with the statute and the form next to every claim.
What is the Oklahoma pass-through entity tax election?
Under the Pass-Through Entity Tax Equity Act of 2019, an Oklahoma S corporation or partnership can elect to pay Oklahoma income tax at the entity level, at the state’s top individual rate (4.5% for 2026) on income allocated to individual owners and 4% on income allocated to corporate owners. The owners then exclude that income on their own Oklahoma returns. Because the entity pays the tax, it is deductible on the entity’s federal return under IRS Notice 2020-75 and does not count against the owners’ federal cap on state and local tax deductions.

The rule
Five facts, each with its source.
Everything below comes from the statute, the Oklahoma Tax Commission’s own forms, and the IRS notice that made the whole arrangement work federally. If a number here ever disagrees with one of them, the source wins and we fix the page.
Only entities that file an Oklahoma partnership or S corporation return can elect.
That means partnerships, LLCs taxed as partnerships, and S corporations. A sole proprietorship or a single-member LLC that reports on Schedule C cannot elect, because there is no entity return for the tax to sit on. If your business is one of those, the rest of this page is a reason to talk to your CPA about whether an S election makes sense first.
The entity pays 4.5% on income allocated to individuals, 4% on income allocated to corporations.
The individual rate is not fixed in the Act; it is whatever Oklahoma’s top individual rate happens to be, which is 4.75% for 2025 and 4.5% for tax year 2026 under HB 2764. If the state’s revenue triggers lower the rate again, the entity-level rate follows. Trusts and estates are taxed like individuals; corporate members and other pass-through members pay 4%.
The election is made on Form 586, and there are three windows to make it.
Any time during the tax year before the one you want it to apply to; within two months and fifteen days after the year begins; or, since tax year 2024, with the entity’s timely filed return, extensions included, with Form 586 attached. Once made, it is binding until revoked on Part 2 of the same form, and a revocation only takes effect for the current year if it is filed within those first two months and fifteen days.
Owners exclude the income on their own Oklahoma return; they do not take a credit.
Oklahoma uses an exclusion, not a credit. The income the entity paid tax on comes off the owner’s Oklahoma return on Schedule 511-A, line 14, with a copy of the Tax Commission’s acknowledgment letter attached. In a loss year, the loss is added back on Schedule 511-B and stays with the entity, which is the first place the election can backfire.
Federally, the entity’s payment is an ordinary deduction, outside the owners’ SALT cap.
IRS Notice 2020-75 confirmed that state income tax paid by a partnership or S corporation is deductible in computing the entity’s income and is not taken into account in applying the individual cap. The 2025 federal tax law raised the cap to $40,400 for 2026; above $505,000 of income it phases down, reaching a $10,000 floor at roughly $606,000. The enacted version did not restrict this election for any profession, though an earlier House draft would have.
The trap
Where the election costs more than it saves.
The election is binding, it covers every owner, and it moves losses as well as income. Four situations where it is the wrong call.
If your state and local taxes already fit under the federal cap, there is nothing to recover.
For 2026 the cap is $40,400 for most households, and it only begins to shrink above $505,000 of adjusted gross income. An owner with $150,000 of pass-through income, $7,000 of property tax and no other state tax has roughly $13,000 of deductible state and local tax and a cap three times that size. The election would simply change which return the deduction appears on. After 2029 the cap returns to $10,000 and this calculus changes for almost everyone.
A loss stays in the entity instead of offsetting your other Oklahoma income.
An electing entity’s Oklahoma loss carries forward on the entity’s own return. The owner adds the loss back on Schedule 511-B and gets no benefit from it that year, even if they have wages, rental income or another business that the loss would otherwise have sheltered. A business with uneven years should think hard before electing in a year that might be red.
A partner in another state may get no credit at home for tax Oklahoma collected.
Oklahoma relieves a nonresident owner of filing here when the electing entity is their only Oklahoma income. Whether the owner’s home state gives credit for Oklahoma tax paid by the entity rather than by the individual depends on that state’s rules, and several do not. The reverse is also true: Oklahoma’s own credit for taxes paid to other states covers wages and personal-service income only, so an Oklahoma resident’s share of another state’s entity tax earns no Oklahoma credit either way.
The entity has to pay in quarterly, in its own name, or the interest runs at 20%.
An electing entity with $500 or more of expected Oklahoma tax must make estimated payments on April 15, June 15, September 15 and January 15, under its own name and federal ID, with a safe harbor of the smaller of 70% of this year’s tax or 100% of last year’s. Owners who were used to paying their own estimates need to stop paying Oklahoma personally on that income and make sure the entity starts, or the household ends up paying twice while the entity pays interest.
The decision
Who it helps, by the numbers.
The election helps the owner whose state and local taxes exceed the federal cap and who sits in a high federal bracket. In 2026 that is, almost by definition, a household above $505,000 of income, where the cap phases down 30 cents for every dollar of income over the threshold until it hits the $10,000 floor at roughly $606,000. Above that line the arithmetic is simple: every dollar of Oklahoma tax the entity pays is a dollar the household could not have deducted, now deducted at the owner’s federal rate. As an illustration: a household above that line with $700,000 of Oklahoma pass-through income has the entity pay $31,500 of state tax, and at a 35% federal rate the deduction is worth about $11,000 a year, for the cost of the election and the entity’s quarterly estimates.
Below the threshold, the question is whether your combined state and local taxes, including the Oklahoma income tax on this very income, exceed $40,400. For most Oklahoma owners under $400,000 of income, they do not, and the election is a wash with a loss-year risk attached. The calculator below runs your own figures.
One more thing worth saying plainly: the election is made by the entity and binds every owner. In a group with several partners at different incomes and in different states, the partner who benefits most and the partner who benefits least are both bound by the same choice, so this is a conversation for the whole partnership and its CPA, not a line item one partner adds in March.

Questions we get
Asked often enough to answer here.
Is the Oklahoma PTE election still allowed after the 2025 federal tax law?
Yes. The House version of the 2025 law would have denied entity-level deductions to owners of service businesses such as medical, legal and accounting practices; that language was dropped before enactment. The enacted law raised the individual SALT cap to $40,000 for 2025 and $40,400 for 2026 and left IRS Notice 2020-75 undisturbed.
Does a single-member LLC qualify?
Not unless it has elected to be taxed as an S corporation. The election is available only to entities that file an Oklahoma partnership return (Form 514) or S corporation return (Form 512-S). A single-member LLC reporting on Schedule C has no entity return to elect on.
When is Form 586 due?
Three windows: any time during the preceding tax year; within two months and fifteen days after the start of the tax year; or, for tax years 2024 and later, with the entity’s timely filed return including extensions, with Form 586 attached. A Form 586 filed late applies to the following year.
How does an owner report income from an electing entity?
The owner subtracts the Oklahoma income covered by the election on Schedule 511-A, line 14, and attaches a schedule showing the entity’s name, federal ID and the amount, plus a copy of the Tax Commission’s acknowledgment letter. Losses from an electing entity are added back on Schedule 511-B.
Can the entity change its mind?
The election is binding until revoked on Part 2 of Form 586. A revocation filed within two months and fifteen days of the start of a tax year takes effect for that year; filed later, it takes effect the following year. The Tax Commission can also revoke an election if the entity does not pay the tax.

This guide is educational and general. It describes Oklahoma and federal rules as published on the date shown in the footer, which can change, and it is not personalized tax, legal or investment advice. Baldwin Financial, LLC does not prepare tax returns; the election is made on the entity’s return and should be decided with the entity’s CPA. The calculator is an illustration using the 2026 federal cap and Oklahoma’s 2026 rate; it ignores the standard deduction, the alternative minimum tax, and other states’ rules, any of which can change the result.
