If you're registered for Ohio sales tax, you must file returns and pay any tax due according to the filing frequency assigned by the Ohio Department of Taxation. This guide focuses on the filing and payment process most relevant to remote sellers and out-of-state businesses using the Ohio Business Gateway. Note that Ohio's due date is the 23rd of the following month — later than most other states.

When to file and pay Ohio sales tax
The Ohio Department of Taxation will assign you a filing frequency (monthly, quarterly, semi-annually, or yearly) after you register your business.
Ohio sales tax returns and payments are due at the same time, by the 23rd of the month following the end of the filing period. This is three days later than the 20th deadline used by most other states — a common source of missed deadlines for businesses managing multi-state compliance. If the 23rd falls on a weekend or holiday, the due date shifts to the next business day.

Important note: Zero returns
Once you have an Ohio vendor's license, you are required to file returns for every assigned period regardless of whether any sales tax was collected. When no sales tax was collected, you must file a zero return electronically through the Ohio Business Gateway.
How to prepare your Ohio sales tax return
Before working on your sales tax return, collect all sales information for the tax period.
Sales transactions
You need to know your total gross sales to Ohio buyers and your taxable sales. Remember Ohio's important SaaS distinction: SaaS sold to businesses (B2B) is taxable, but SaaS sold to individuals for personal use (B2C) may not be taxable.
Key reporting figures
In addition to your gross Ohio sales, filing a return requires:
- Total sales and income
- Taxable sales by county (Ohio uses a county-based rate structure — you charge the combined rate for the buyer's county)
- Non-taxable sales and exemptions
- Deductions and adjustments
- Total sales tax collected from customers during the filing period
How to complete and file an Ohio sales tax return
Ohio sales tax returns are filed electronically through the Ohio Business Gateway and must be reported in US dollars.
Step-by-step: file an Ohio sales tax return
1. Collect all necessary information
Gather your sales records for the tax period, organized by county. Ohio's county-based rate structure means you need to track sales by the buyer's county to apply the correct combined rate.
2. Log in and file online
- Log in to the Ohio Business Gateway.
- Navigate to your Sales and Use Tax account.
- Select the filing period you want to file.
- Enter your gross sales, taxable sales by county, exemptions, and total tax collected.
- Review and submit your return.
3. Receive confirmation
After submitting, you will receive a confirmation number. Save this as your record of filing.
How to pay sales tax in Ohio
Ohio requires most businesses to file and pay electronically through the Ohio Business Gateway. You can pay directly within the portal after filing your return. Accepted payment methods include:
- Credit card (Visa, MasterCard, Discover)

What happens after filing and paying Ohio sales tax
After filing and paying, keep a copy of your return and payment confirmation for your records.
- Save your filing confirmation and payment receipt
- Keep records supporting the reported amounts
- Continue filing according to your assigned frequency, remembering Ohio's 23rd due date
- File a zero return when required

Late filing penalties and interest
If you miss an Ohio sales tax filing deadline, file as soon as possible. Failure to file returns and remit collected tax on time results in penalties and interest charges that increase the longer you wait.
For current penalty rates and interest charges, refer to the Ohio Department of Taxation website.
