Ohio LLC loophole: the $250,000 business income deduction explained

What is the LLC loophole in Ohio?

The Ohio LLC loophole is the business income deduction in ORC 5747.01(A)(31). It lets an individual subtract the first $250,000 of business income from Ohio adjusted gross income each year, and it pairs with ORC 5747.02(A)(4), which taxes whatever business income is left at a flat 3% instead of the ordinary rates. The owner reports the business income on the personal Ohio IT 1040, attaches Schedule IT BUS, and the deduction comes off there.

People call it the LLC loophole because the typical beneficiary is an owner of a small pass-through business, and the limited liability company is the most common form that business takes. Critics, led by Policy Matters Ohio, picked the name to make a point: the deduction is a tax break that depends on how income is labeled, not on anything the business does. Supporters prefer "small business deduction" or "business income deduction," the terms the Department of Taxation uses.

The name is a misnomer in one important way. Nothing in the statute mentions LLCs. The deduction attaches to business income, and business income can come from a sole proprietorship with no state filing at all, from a general partnership, from an S corporation, or from an LLC. An Ohio LLC taxed as a C corporation gets no deduction, because its profit is taxed at the entity level and never reaches a Schedule IT BUS. If you are weighing entity types, our guide to Ohio business entity types covers the differences.

It is also not a loophole in the sense of an accident. The General Assembly wrote it on purpose, expanded it twice, and has voted to keep it through every budget fight since. Whether it is good policy is a separate question, covered below.

Who qualifies for the Ohio business income deduction?

Any individual who reports business income on an Ohio IT 1040 can claim the business income deduction. That covers sole proprietors filing a federal Schedule C or Schedule F, partners and LLC members receiving a Schedule K-1 from a partnership, shareholders receiving a K-1 from an S corporation, and single-member LLC owners whose LLC is disregarded for tax purposes. Trusts and estates are outside the deduction; it is a personal income tax provision.

The owner claims it, not the business. A partnership or S corporation files an informational return and passes its income out to the owners, and each owner takes the deduction on their own return against their own share. Two equal partners in a business that earns $400,000 each report $200,000, and each deducts the full $200,000, because each is under the $250,000 cap. The cap is per return, not per business.

The $250,000 figure is for single filers, heads of household, and married couples filing jointly. A married person filing separately gets $125,000. A couple filing jointly does not get $500,000; the cap applies once to the joint return.

The deduction is limited to the amount of business income on the return. If your net business income is $60,000, you deduct $60,000 and owe no Ohio tax on it. The unused part of the $250,000 does not carry forward and cannot be applied to wages or investment income.

The entity's own tax treatment matters

The deduction follows the federal pass-through path. An LLC that files as a partnership or a disregarded entity passes income to the owners, who claim the deduction. An LLC that has elected S corporation treatment does the same through its K-1s. An LLC that has elected to be taxed as a C corporation pays Ohio no income tax at all, since Ohio has no corporate income tax, but its owners also claim no business income deduction on the salary or dividends they take out. Our overview of Ohio LLC taxes walks through each classification.

What counts as business income versus nonbusiness income?

Business income, defined in ORC 5747.01(B), is income from transactions and activity in the regular course of a trade or business, including income from property that is an integral part of the business. Nonbusiness income, defined in ORC 5747.01(C), is everything else: wages from an employer, interest and dividends on personal investments, pensions, Social Security, and most capital gains on personal assets.

The line matters because only business income gets the deduction and the 3% rate. The same dollar can fall on either side depending on how it is earned. Rent from a building the business operates out of is business income. Rent from a vacation condo you own personally usually is not. Interest on the business's operating account is business income. Interest on your personal savings account is not.

Pay from a company you own at least 20% of

One rule surprises S corporation owners. ORC 5747.01(B) treats compensation and guaranteed payments paid by a pass-through entity to an investor who directly or indirectly owns at least 20% of that entity as business income. So the W-2 salary an S corporation pays its majority owner counts toward the $250,000 deduction along with the K-1 profit. A 10% owner's salary does not; for that person the salary is ordinary wage income and only the K-1 share is business income.

Common items and where they land

Gray areas exist, especially for rental activity, income from selling a business interest, and income from an activity that looks more like an investment than a trade. The Department of Taxation audits Schedule IT BUS claims, and the burden is on the taxpayer to show the income is business income. If a position is aggressive, have an Ohio CPA sign off before you file.

Worked example: $400,000 of business income

Here is how the deduction and the 3% rate work for an owner with $400,000 of business income and no other income, using tax year 2026 rates. Under HB 96, nonbusiness income above $26,050 is taxed at a flat 2.75% for 2026; the first $26,050 is taxed at zero. The comparison column shows what the same $400,000 would cost if it were nonbusiness income, such as wages.

The owner pays $4,500 instead of about $10,284, a difference of roughly $5,800. Almost all of the saving comes from the $250,000 deduction, not the 3% rate. The rate on business income above the deduction, 3%, is actually a quarter point higher than the 2.75% nonbusiness rate for 2026. The deduction simply outweighs it until business income gets very large; by our arithmetic the two columns do not cross until business income is above roughly $2.7 million, and even then the difference is small.

The example leaves out personal exemptions, credits, and any nonbusiness income, all of which change the real return. An owner with $400,000 of business income and a spouse earning $90,000 in wages would pay 2.75% on the wages above the zero band and 3% on the $150,000 of business income after the deduction. Run the actual numbers with a preparer or the Department's IT 1040 instructions.

Smaller numbers

Most Ohio owners never reach the cap. A sole proprietor with $80,000 of net profit deducts all $80,000 and owes no Ohio income tax on it. The same $80,000 earned as wages from an employer would produce about $1,484 of Ohio tax at 2026 rates. That is the deduction working as its sponsors intended: a few hundred to a few thousand dollars a year for ordinary small businesses.

History: from 50% to 100%, and the HB 96 decision to keep it

Ohio created the business income deduction in the 2013 state budget, when it allowed owners to deduct 50% of the first $250,000 of business income. The 2015 budget raised the share to 75% for that year and then to 100% of the first $250,000 beginning with tax year 2016, and added the flat 3% rate on business income above the deduction. The structure in place today dates from that 2016 change.

The deduction has been challenged in nearly every budget since. In 2019 the House version of the budget would have cut the cap to $100,000; the final bill kept $250,000 but briefly carved lawyers and lobbyists out of the deduction, a carve-out that was later repealed. Proposals to shrink or phase down the deduction surfaced again in the 2021 and 2023 budget cycles and did not pass.

HB 96, the state operating budget for fiscal years 2026 and 2027 signed in 2025, was the latest test. The bill's income tax change was on the nonbusiness side: it collapsed Ohio's remaining brackets into a flat 2.75% rate on nonbusiness income over $26,050 beginning with tax year 2026, down from a 3.125% top rate for 2025. The business income deduction and the 3% business rate were left exactly where they were. The General Assembly had the opportunity to change them and chose not to.

One side effect of HB 96 is worth noting. Before 2026, the 3% business rate was a discount from the top nonbusiness rate. With the nonbusiness rate now at 2.75%, the business rate is slightly higher than the ordinary rate for the first time. The $250,000 deduction still makes business income cheaper to earn in almost every real case, but the 3% rate is no longer a benefit on its own.

The policy debate: small business relief or a giveaway?

The business income deduction is one of the most argued-over lines in the Ohio tax code. The two sides agree on what it does and disagree on whether it is worth what it costs. Here is each position as its proponents make it.

The case for the deduction

Supporters, including the National Federation of Independent Business and the business groups that lobbied for it, say the deduction lets owners of small pass-through businesses keep money they would otherwise send to Columbus, and that owners reinvest that money in equipment, hiring, and wages. They point out that pass-through owners pay tax on profit whether or not they take it out of the business, so a deduction on the first $250,000 cushions the years when profit is reinvested. They also argue it makes Ohio competitive with neighboring states for people deciding where to start a business, and that the General Assembly's repeated votes to keep it reflect broad support.

The case against it

Critics, led by Policy Matters Ohio, make three arguments. First, cost: the deduction reduces state revenue by an amount Department of Taxation estimates have put at roughly a billion dollars a year, money that would otherwise fund schools, local governments, and services. Second, distribution: because the deduction is capped per return rather than phased out by income, high earners with large business income receive the full $250,000 deduction and the largest dollar benefit, while a part-time Etsy seller with $5,000 of profit saves very little. Third, results: critics say there is no evidence the deduction has produced measurable job growth, and that it mainly rewards income that already existed under a new label. They also note that a wage earner and a contractor doing identical work can owe very different Ohio tax, which they see as unfair.

Where it stands

Both sides have data. The deduction is claimed on hundreds of thousands of Ohio returns a year, most of them with modest business income, which supports the small business framing; a large share of the dollar value goes to a small number of high-income returns, which supports the critics. Neither side expects the deduction to disappear soon. The practical takeaway for an owner is that it exists, it has survived every attempt to shrink it, and it should be claimed if you qualify.

What forming an LLC actually changes for Ohio taxes

Forming an LLC does not change your Ohio income tax. A sole proprietor who forms a single-member LLC files the same federal Schedule C, reports the same net profit on the Ohio IT 1040, and claims the same business income deduction on Schedule IT BUS. The deduction was available before the LLC existed and is unchanged after. Our guide to Ohio single-member LLC taxes covers the mechanics.

What the LLC changes is liability and structure. An LLC versus a sole proprietorship comes down to separating business debts from personal assets, holding property and contracts in the company's name, and having a vehicle that can add owners later. Those are real reasons to form one. Saving Ohio income tax is not one of them, because the tax result is identical.

The one tax decision that does interact with the deduction is the S corporation election. An LLC taxed as an S corp pays its owner a salary and passes the rest through as profit, which can reduce federal self-employment tax. For Ohio purposes, both the salary (for a 20%-plus owner) and the K-1 profit are business income under ORC 5747.01(B), so the election does not cost you the deduction. It also does not increase it; the $250,000 cap is the same either way.

If you form an LLC for the liability protection, do it properly. File the Articles of Organization, name a statutory agent, get an EIN if you need one, keep business money in a business account, and follow the ongoing requirements. None of it changes the Schedule IT BUS, but all of it protects the limited liability you formed the company to get.

City income tax: no deduction

The business income deduction applies only to the Ohio state income tax. Ohio municipalities levy their own income tax under ORC Chapter 718, and that tax has no $250,000 deduction and no 3% rate. A sole proprietor or partnership in a city with a 2.5% income tax pays 2.5% on the full net profit from the first dollar, and the owner's resident city may tax the same profit as well, subject to whatever credit the city allows.

This catches owners who assume "no Ohio tax on the first $250,000" means no tax at all. A Columbus owner with $200,000 of net profit owes nothing to the state on it but owes Columbus 2.5%, or $5,000, on the net profit. Our guide to Ohio municipal income tax for businesses covers who files, the net profit return, and the centralized filing option through the Department of Taxation.

School district income taxes, where they apply, are also separate from the state deduction. Some school districts tax earned income, which can include self-employment profit, and the Schedule IT BUS deduction does not reduce it.

This is not tax advice

This page describes the Ohio business income deduction as the statutes and the Department of Taxation's forms set it out. It is not advice about your return. Whether a particular dollar is business income, how an S corporation salary should be set, and whether a rental activity rises to a trade or business are questions for an Ohio CPA or tax attorney who has looked at your facts. The Department's instructions for Schedule IT BUS are the authoritative source for the form itself.

If you decide an LLC makes sense for liability reasons, every Ohio LLC must name a statutory agent in its articles (ORC 1706.09). We serve as the Ohio statutory agent for $49 a year, flat, from our office in Litchfield. You file the appointment or we do after you e-sign consent in the portal. We scan state mail the same business day, and treat lawsuit papers as urgent. Our guide on how to start an LLC in Ohio covers the rest of the filing.
