About Ohio employer tax information

With Square, you can run payroll, pay your taxes and stay ahead of the compliance to focus on running your business. This guide is intended for your state taxes only. It’s important to note that laws vary by jurisdiction, and this guide does not attempt to address all jurisdictions or federal taxes — for example, counties or cities often have requirements that differ from federal and state law.

If you become liable for unemployment taxes and register an account in a later quarter, it may be necessary to file these taxes retroactively. Visit the Ohio website or contact the OH Department of Job and Family Services directly to determine your requirements and ensure any outstanding tax filings are completed promptly to avoid penalties.

Payroll reciprocal state agreements

A reciprocal agreement is an agreement between two states that allows employees that work in one state but live in another to request exemption from tax withholding in their employment state. This means that the employee would not have income tax withheld from their paycheck for their employment state; they would only pay income taxes to the state where they live.

A Non-Residency Certificate (or statement or declaration), is used to declare that an employee is a resident of a state which has a reciprocal agreement with their work state and therefore chooses to be exempt from withholding income tax in their work state. A non-resident employee qualifying for this exemption must complete and file this declaration with his or her employer as authorization for the employer to stop withholding state income taxes where the employee works. Employers should keep the non-residency certificate on file.

Ohio has reciprocal agreements with:

  • Indiana 

  • Kentucky 

  • Michigan 

  • Pennsylvania 

  • West Virginia

Non-resident employees should file IT-4NR.

Review semi-monthly city tax filing requirements
