Starting a business in Ohio: the municipal income tax nobody mentions

Here is the situation that catches people. You form an LLC in Columbus, you do a fortnight of work at a site in Westerville, another job in Dublin, and one afternoon in Worthington. At the end of the year you owe a municipal net profit return to each of those places, apportioned by where the work was actually done, on top of your Ohio return and your federal one. Nothing in the formation process warns you, because the Secretary of State does not collect the tax and has no reason to mention it.

Municipal rates run 0.5%–3.0% (most cities 1.5%–2.5%). That is not a rounding error on a small business: on $70,000 of profit, a 2% city rate is $1,400 — fourteen times what Ohio charged you to exist.

The rest of Ohio is genuinely light. Registering for sales tax is free, there is no state business licence, and the entity-level taxes that bite in Illinois or California do not exist here. If you want the formation mechanics rather than the operating ones, the LLC hub has every state fee side by side. What follows is what happens after.

Ohio does not collect municipal income tax centrally for most small businesses. Three kinds of administrator exist, and your first job is finding out which one your city uses, because it decides where you register, where you file and where the cheque goes.

The liability test is physical. It is where the work was performed, not where the client sits, not where you invoice from and not where the LLC is registered. A consultant who works from a laptop at home in one municipality all year has one city. A trades business, an installer, a cleaner, a photographer or anyone whose work happens at the customer's address can easily have four.

Two practical consequences. First, keep a record of days and locations from day one — reconstructing a year of site visits in April is miserable and the apportionment is what the return asks for. Second, most cities also want quarterly estimated payments once the liability is real, so the first year is where the arrears build up quietly.

Ohio built an answer to this. A business can elect centralized filing of the municipal net profit tax with the Department of Taxation: one registration, one return through the Ohio Business Gateway, one payment, and the state distributes the money to the municipalities. The election is made by the 15th day of the fourth month of the tax year.

The Department is explicit that sole proprietors and disregarded entities are not eligible. A disregarded entity includes the single-member LLC that most founders reading this page have just formed. So the reader who would benefit most from filing one return instead of four is the one the fix was never open to.

It is also a genuine reason to think about entity structure before you file, rather than after. Adding a second member changes how the business is taxed federally, and in Ohio it also changes which municipal filing regime you can use. That is not a reason on its own to add a partner — but it is a factor nobody tells you about, and it is easier to decide at the start.

Ohio has no general state business licence. What it has is a vendor's licence, and it is a county matter rather than a city one: $25 once, from the county fiscal officer or auditor or instantly through the Ohio Business Gateway, one per fixed sales location. There is no annual renewal fee — it stays in force until the business dissolves or ownership changes. If you sell across counties rather than from a fixed place, the transient vendor's licence is $50 from the Department of Taxation.

Whether you need one at all depends on the second Ohio trap, which is subtler than the first: Ohio taxes tangible goods and a defined list of services, so "I sell services, so I have no sales tax" is a guess rather than a rule here.

On the taxable-services list: landscaping and lawn care, building maintenance and janitorial work, employment and employment-placement services, security services, and electronic information services. Most professional services — legal, accounting, consulting, design — are not on it. If your trade is anywhere near that list, read the Department of Taxation's enumeration before you send your first invoice, because charging the tax late is much harder than charging it from the start.

Ohio is one of four monopolistic states. You cannot buy workers' compensation from a private insurer here at all — cover comes from the Ohio Bureau of Workers' Compensation state fund, and it is required from the first employee, part-timers and family members included. There is no headcount grace period of the sort Missouri and Wisconsin give.

Set against the municipal tax, Ohio's state-level demands are close to nothing, and it is worth being precise about how little.

So the honest summary of Ohio is: cheap to own, fiddly to operate, and the fiddle is entirely municipal. If you know from the start which cities you will work in and you keep a log of where the work happened, it is manageable. If you find out in April, it is not.
