Some school districts levy an income tax. If you lived in (resided) or were domiciled in one of these districts for all or part of the year, you are required to file a school district income tax return, Ohio form SD 100. See the School District Income Tax website for more information. The instruction booklet for filing the return will walk you through the process.

Filing Your Tax Return

Where do I mail my forms?

Always sign your return before mailing. If you are enclosing a payment with your return, be sure to enclose Ohio form IT 40P/IT 40XP (or SD 40P/SD 40XP) with your check or money order. This will ensure proper crediting of your payment. For a full list of mailing addresses, see this page.
