Ohio

Ohio state tax filings.

Which agencies Ohio uses, which forms they take, and what Ohio does differently. Every entry carries the date it was checked against the agency's own material.

Who you deal with in Ohio

Ohio Department of Taxation

Publishes the STEC B and STEC U exemption certificate forms. Does not receive or approve completed certificates; the purchaser completes one and the vendor retains it.

Fill-in PDFs from the department's forms library; no portal filing exists for the certificate

Ohio Department of Job and Family Services

Unemployment insurance employer account

The SOURCE, Ohio's unemployment insurance system for employers

County Auditor, for the county where sales are made

The vendor's license, which applies instead if the business has a physical location in Ohio

OH|TAX eServices, or the county auditor's office

3 separate agencies, on 3 separate systems. Doing something with one does nothing to the others.

What Ohio does differently

  • Fifteen days, and the clock starts at closing. Most states measure from the end of a month or a quarter. Ohio measures from the day the business closed or merged, which means the deadline can land before a business has finished shutting down its bank accounts.
  • Fifteen days from the final sale. This is one of the shortest sales tax deadlines in the country and it is measured from a sale rather than from a period end, so it can expire before the business has finished shutting down.
  • Fifteen days from when liability begins, and 15 days again at the end. Ohio is unusually consistent about this number and unusually short with it. Most states give you 30 days at one end and nothing published at the other.
  • Two registrations share one name in conversation. Ohio issues a seller's use tax license to out-of-state sellers and a vendor's license to businesses with an Ohio location. They have different forms, different fees, and different offices. Searching for Ohio sales tax registration mostly returns the second one, so out-of-state sellers arrive expecting a county filing and a $50 fee that are not theirs.
  • Two forms, one decision: STEC B is a blanket certificate covering ongoing purchases from one named vendor, STEC U covers a single transaction. Handing a vendor the wrong one is the most common redo.
