Ohio's Pass-Through Entity Tax in 2026: Who Should Elect It, and Who Shouldn't

If you own an S corporation or partnership in Ohio, the state lets your business pay Ohio income tax at the entity level instead of on your personal return. The business pays 3% on its income and deducts that payment on its federal return. You then claim a refundable credit on your Ohio return. The point is a full federal deduction for Ohio tax that the SALT cap would otherwise limit.

The federal SALT cap rose to $40,400 for 2026. So is the Ohio pass-through entity tax still worth it? For owners with household income above about $505,000, or with state and local taxes above the cap, usually yes. For owners with less than $250,000 of Ohio business income, usually no. The reason is one national guide rarely explains: Ohio already exempts the first $250,000 of business income, so there’s little Ohio tax to move. If the election makes sense for your 2026 return, you need to decide before December 31.

Key takeaways

Ohio’s elective pass-through entity tax (Form IT 4738) is 3% of the entity’s income. The business pays it and deducts it federally, outside the SALT cap.
The 2026 SALT cap is $40,400, but it shrinks once household modified AGI passes $505,000 and drops to $10,000 at about $606,333. Those owners get the most from the election.
Ohio’s $250,000 business income deduction only applies on your personal return, so the business often pays more than you owe. The excess comes back as a refund, which may be taxable on your next federal return.
Owners with less than $250,000 of Ohio business income usually gain little or nothing.
The election is made one year at a time, binds every owner, and can’t be reversed. To deduct the tax on your 2026 return, make the election and the payment before December 31, 2026.

How Ohio’s pass-through entity tax works

Normally, an S corporation or partnership doesn’t pay Ohio income tax itself. The profit flows through to the owners, who pay Ohio tax on their personal returns. On your federal return, that Ohio tax is an itemized deduction, and it counts against the SALT cap along with your property taxes.

In IRS Notice 2020-75, the IRS said state income taxes paid by the entity itself are a business deduction, so the SALT cap doesn’t apply to them. Ohio followed in 2022 with an optional entity-level tax. According to the Ohio Department of Taxation, here’s how it works:

Who can elect: S corporations, partnerships, and LLCs taxed as either. A single-member LLC that’s disregarded for federal tax purposes can’t. (If you’ve elected S corporation status for your LLC, you can.)
The rate: 3% for 2026, which matches Ohio’s rate on business income.
The base: all of the entity’s Ohio income. Compensation paid to anyone who owns 20% or more is added back, so the salary you pay yourself from your S corporation is taxed at the entity level too. Ohio also adds back certain other items, such as some payments to family members and related companies.
Every owner is in: the election binds all owners. Nobody can opt out.
One year at a time: you decide each year, and once you’ve elected for a year, you can’t reverse it.
Your personal return: you add your share of the entity’s tax back into your Ohio income, then claim a refundable credit for it.

Put simply, the business prepays your Ohio income tax in a form the IRS lets it deduct. Ohio then settles up with you on your personal return.

What the $40,400 SALT cap changed, and what it didn’t

The One Big Beautiful Bill Act raised the federal SALT deduction cap from $10,000 to $40,000 for 2025 and $40,400 for 2026. The higher cap phases down as income rises. For every dollar of modified adjusted gross income (MAGI) above $505,000, the cap drops by 30 cents, until it bottoms out at $10,000 at about $606,333 of MAGI. Married couples filing separately get half of each figure. The higher cap runs through 2029 and reverts to $10,000 in 2030. Congress left the pass-through entity tax workaround in place.

Here’s what that means for Central Ohio business owners:

MAGI under $505,000 and you itemize: your Ohio income tax and property taxes probably fit under $40,400 already. The election mostly moves a deduction you already get from one return to another.
MAGI over $505,000: your cap is shrinking, and above roughly $606,000 it’s back to $10,000. Property taxes on a larger home in Franklin or Delaware County can use up that $10,000 on their own, which leaves your Ohio income tax with no federal deduction at all unless the business pays it.
You take the standard deduction: you get no federal benefit from Ohio income tax you pay personally. Paid through the business, it becomes deductible on top of the standard deduction.

The Ohio wrinkle: your $250,000 business income deduction

This is where national articles on pass-through entity taxes go wrong for Ohio owners.

On your personal Ohio return, the first $250,000 of business income is fully deductible ($125,000 if married filing separately), and business income above that is taxed at a flat 3%. Wages you draw from a business you own at least 20% of count as business income. So many Ohio owners pay little or no state income tax on what their business earns.

The entity-level tax doesn’t get that deduction. The business pays 3% on all of its income, including your salary. The $250,000 deduction only shows up when you file your personal return. There, Ohio figures out what you actually owe, applies the business’s payment as a credit, and refunds the difference.

That splits the payment into two parts:

The part that matches tax you really owe (3% of your business income above $250,000). This is where the lasting federal savings come from.
The part that comes back as a refund. The IRS hasn’t issued guidance on whether a refund of pass-through entity tax is taxable, and the AICPA has pointed out the uncertainty. The cautious approach is to assume the refund is taxable on your federal return the year you receive it, since the business already deducted it. Under that view, the refunded portion is a one-year deferral, not a permanent savings.

So the real question isn’t “Are my state and local taxes over the cap?” It’s “How much Ohio tax do I actually owe on business income above $250,000, and would I lose the federal deduction for it without the election?”

Two Central Ohio examples, with the math

These are simplified illustrations with rounded numbers. Your figures will differ.

A Dublin consulting firm earning $700,000: the election pays

Dana owns 100% of a consulting S corporation. In 2026 she pays herself a $180,000 salary, and the company earns another $520,000 in profit, for $700,000 of Ohio business income. She’s married, files jointly, and pays $14,000 a year in property taxes on her Dublin home.

At that income, her SALT cap is fully phased down to $10,000, and her property taxes use all of it. Any Ohio income tax she pays personally gets no federal deduction.

Without the election: Dana owes Ohio about $13,500 (3% of the $450,000 above the $250,000 deduction), with no federal deduction for it.
With the election, the company pays 3% on roughly $700,000, about $21,000, and deducts it on its federal return. In Dana’s 35% bracket, that cuts her 2026 federal tax by about $7,350. When she files her Ohio return, she still owes about $13,500, so roughly $7,500 comes back as a refund.
The following year: if that $7,500 refund is taxable, it adds about $2,600 to her 2027 federal tax.

Net result: about $4,700 of permanent federal savings, plus a one-year deferral on the rest. Consulting is a specified service business, so at Dana’s income she doesn’t get the qualified business income deduction, and nothing offsets the savings. Even after the cost of preparing one more return, the election is clearly worth it.

A Columbus HVAC company earning $240,000: skip it

Marcus owns 100% of an HVAC S corporation. He pays himself $90,000, and the company earns $150,000 more, for $240,000 of Ohio business income. He’s married, files jointly, takes the standard deduction, and is in the 22% federal bracket.

Without the election: all $240,000 falls under Ohio’s $250,000 business income deduction, so Marcus owes no Ohio income tax on it.
With the election: the company pays 3% of $240,000, about $7,200. The deduction saves roughly $1,300 in 2026 federal tax. That’s less than 22% of $7,200 because the deduction also shrinks his 20% qualified business income deduction. The following spring, Marcus files his Ohio return, owes nothing on his business income, and gets the full $7,200 back.
The following year: if the refund is taxable, it costs him about $1,600 in 2027 federal tax.

Net result: about break-even, or a small loss, before paying for an extra return and leaving $7,200 with the state for most of a year. Even if the refund turns out not to be taxable, $1,300 is thin for the cash and paperwork involved. Marcus should skip it.

Who should elect, and who should skip

Strong candidate	Probably skip
Household MAGI above $505,000, especially above about $606,000	Ohio business income under $250,000
Ohio business income well above $250,000	MAGI under $505,000, you itemize, and total SALT is under $40,400
Property taxes already use up your SALT cap	Some owners are C corporations, retirement plans, or nonprofits
You take the standard deduction but owe meaningful Ohio tax	The business can’t front 3% of all income, owner salaries included

Partnerships and S corporations with several owners need extra care. The election binds everyone, so one owner can come out thousands ahead while another gets nothing but a delayed refund. Owners that aren’t individuals, such as a C corporation or a retirement plan, generally can’t use the credit at all, so the tax paid on their share is simply lost. Run the numbers for every owner before you elect, and get agreement in writing.

2026 deadlines and the cash-flow cost

Starting with the 2026 tax year, Ohio moved its estimated payment dates for the entity tax to match the federal calendar: April 15, June 15, September 15, and January 15 of the following year.

Ohio accepts the election in two ways. You can file the IT 4738 return by its April 15 due date (or the extended date). You can also file the EPTE-ELEC election form, which can be submitted at any time, including before year-end.

For the federal deduction, timing matters more than Ohio’s due date. A cash-basis business deducts the tax in the year it pays it. An accrual-basis business generally needs the election in place before year-end to deduct the tax that year. The practical rule for a 2026 deduction: file the EPTE-ELEC and make the payment before December 31, 2026. If you wait until you file the return in 2027, the deduction likely moves to your 2027 return.

Plan for three costs:

Interest on missed quarters. If you decide this fall to elect for 2026, the April, June, and September estimates have already passed. Ohio charges an interest penalty on late or missed estimated payments. For owners who benefit, it’s usually small next to the federal savings, but it belongs in the math.
Cash parked with Ohio. The business pays 3% on everything, and the refund for the portion covered by the $250,000 deduction doesn’t arrive until your personal Ohio return is processed. For Dana, that’s about $7,500 tied up from late 2026 into spring 2027.
Your personal estimates. Ohio won’t move personal estimated payments you’ve already made over to the business. If the business elects, adjust your remaining personal estimates instead.

Common mistakes with the Ohio election

Electing because a national article said to. Most pass-through entity tax content is written for owners in states like California, where the entity rate is 9.3%. Ohio’s 3% rate and $250,000 deduction change the math.
Looking only at the business return. The benefit shows up on each owner’s federal and Ohio returns. Model both before deciding.
Missing year-end. A payment made in January 2027 generally gives you a 2027 deduction, not a 2026 one. Build the decision into your year-end tax planning.
Treating last year’s answer as permanent. Income changes, the cap rises 1% a year through 2029, and it returns to $10,000 in 2030. An owner who should skip the election today may want it in 2030. Revisit it every fall.

Is the Ohio pass-through entity tax right for your business?

For most owners, the Ohio pass-through entity tax fits one specific situation: high household income, Ohio business income well above $250,000, and state and local taxes the SALT cap won’t let you deduct. In that situation, it produces real savings every year. Outside it, the election mostly moves money around and adds another return to file.

The date that matters is December 31. If your business had a strong 2026, book a year-end meeting with our tax planning team before Thanksgiving. We’ll model the election for every owner and compare it with not electing. If the numbers work, we’ll handle the EPTE-ELEC form and the payment.
