Semi-Monthly City Tax Filers

Most Ohio city taxes are due on a monthly or quarterly basis. However, some Ohio cities have added a new semi-monthly filing requirement for employers who withhold more than $1,000 in city income tax from their employees in a month, or more than $12,000 in a year.

If your city taxes are reported to one of the collection agencies listed below, you can visit their page for more information on semi-monthly filing requirements:

For all others cities that aren’t members of the above, please contact your local income tax agency to inquire about semi-monthly filing requirements.
