Ohio sales tax filing rules
Good to know
Ohio returns are due the 23rd of the month following the period — one of the few non-20th states.
Timely-filing discount
Discount of 0.75% of tax due for timely filers.
Filing Ohio sales tax late
Ohio charges a late-filing and late-payment penalty plus interest on any unpaid tax, and most states apply a minimum penalty even on a zero return. Filing late also forfeits the timely-filing discount described above. File on time — even a return with no tax due must be filed. Confirm current penalty amounts with the Ohio Department of Taxation.
