Ohio Bookkeeping Services

Ohio looks friendly on paper and gets complicated fast. There is no corporate income tax — instead there is the Commercial Activity Tax, charged at 0.26% on Ohio taxable gross receipts above a $6 million annual exclusion from tax year 2025 onward. That exclusion means most small businesses owe nothing, which is exactly why they stop tracking the number. The harder problem is municipal: Ohio has hundreds of cities and villages levying their own income tax, each with its own rate and its own filing, and many administered through RITA or CCA rather than the state. Payroll withholding follows where the work is performed, which in a hybrid-working world is a bookkeeping question before it is a tax one. We have kept books for businesses remotely since 2005, and dedicated bookkeepers from $75/month keep every one of those filings tax-ready.

Ohio’s Small-Business Tax Landscape

Ohio Department of Taxation, checked 3 October 2026. Municipal rates are set locally and change; confirm your city’s rate and administrator, and your CAT position, with the Department or your CPA.

The CAT Exclusion Is Not a Reason to Stop Counting

From tax year 2025 the Commercial Activity Tax exclusion is $6 million of Ohio taxable gross receipts, at a rate of 0.26% above it. For most small businesses that means no CAT liability, and the natural response is to stop thinking about it.

That is a mistake for two reasons. First, the threshold is measured on gross receipts sourced to Ohio, not profit — a low-margin distributor or a reseller can approach $6 million while earning very little, and will not notice until it has crossed. Second, if you do cross, you need a credible figure for Ohio-sourced receipts across the whole year, and that is not something you can reconstruct from a bank balance in January.

The bookkeeping job is unglamorous and cheap: revenue recorded gross, sourced consistently, reviewed monthly. It costs nothing while you are under the threshold and saves a great deal if you approach it.

Municipal Income Tax: The Part That Actually Hurts

Ohio is one of the few states where city-level income tax is a routine part of running a small business. Hundreds of municipalities levy their own, at their own rates, with their own returns, and a large share are administered by the Regional Income Tax Agency or the Central Collection Agency rather than the state.

For an employer this is a payroll problem with a bookkeeping root. Withholding generally follows where the work is performed, so an employee splitting time between a Columbus office and a home in a neighbouring municipality can generate obligations in more than one place. Get the record of where work happened wrong, and the withholding is wrong, and the correction lands months later.

We do not interpret municipal law for you — that is your CPA’s territory. What we do is keep payroll records and the general ledger in a state where the answer is derivable: runs recorded accurately, liabilities reconciled to what was actually remitted, and each municipality tracked separately rather than lumped into one catch-all account. Our payroll processing is $50 per run plus $10 per employee.

Sales Tax: 5.75% Plus a County Layer

Ohio’s state sales tax rate is 5.75%, and counties and transit authorities add their own on top, so the rate that applies depends on the county the sale is sourced to. For a business selling across the state, that means the rate is a per-transaction fact rather than a single figure.

The reconciliation that matters is between the tax your system collected and the tax you actually remitted. When those drift apart — through a mis-set rate, an exempt sale coded wrongly, or a refund processed without reversing the tax — the gap sits on the balance sheet until somebody looks. We reconcile it monthly, as part of the close.
