To file sales tax in Ohio, you submit a return electronically through the Ohio Business Gateway at gateway.ohio.gov, using the vendor’s license and Taxpayer Identification Number tied to your OH|ID account. Returns are due on the 23rd day of the month after your reporting period closes, and the tax you report combines Ohio’s 5.75% state rate with any county and transit authority rates that apply, which can push the combined rate up to 8.75%.1Ohio Department of Taxation. Sales and Use Tax Most vendors use the Universal Sales Tax Return (UST-1); businesses reporting use tax use the Universal Use Tax Return (UUT-1).2Ohio Department of Taxation. UST-1 Data File Upload
What You Need Before You File
You cannot file an Ohio sales tax return without three things in place: an OH|ID account, an active vendor’s license, and the Taxpayer Identification Number the license gives you.
The OH|ID account is Ohio’s single sign-on for state services, including the Business Gateway. You create one at ohid.ohio.gov by verifying an email with a one-time PIN, entering your personal information, choosing a username and password, and setting up a recovery method.3Ohio.gov.

Ohio law requires anyone making retail sales of tangible personal property or taxable services to hold a vendor’s license before collecting tax.4Ohio Department of Taxation.

Ohio Revised Code 5739.99 – Penalty A county vendor’s license covers a fixed location within one county; a transient vendor’s license covers temporary sales across counties; a service vendor’s license covers certain statewide service providers. As of April 2025, the fee for county and transient licenses is $50, raised from $25 under HB 366.6Ohio Department of Taxation. Vendor’s License Fee Change Coming Soon You apply through the Ohio Business Gateway using your OH|ID login, and you need your Federal Employer Identification Number, your NAICS code, and an estimate of annual tax liability. That estimate matters because Ohio uses it to set your initial filing frequency.
Vendor’s licenses do not transfer. If your business changes ownership or entity type, the new entity applies for its own license and the old one is cancelled.
How Ohio Sets Your Filing Frequency
Ohio assigns you one of three filing schedules based on how much tax you collect:
- Monthly filing is the default for vendors, transient vendors, out-of-state sellers, and direct pay permit holders with higher tax liabilities.
- Semi-annual filing is available when your tax liability runs under $1,200 per six-month period.
- Quarterly filing applies to direct pay permit holders and consumer use tax accounts.
Your assigned frequency shows up in your Gateway account. If your volume changes significantly, Ohio can reassign you.
The Filing Deadline
Every schedule uses the same due date pattern: the 23rd day of the month following the close of the reporting period.1Ohio Department of Taxation. Sales and Use Tax A monthly filer’s January return is due February 23. A semi-annual filer’s return is due the 23rd of the month after the assigned six-month period closes.
File on time even when you had no taxable sales. A zero return still has to be submitted, and skipping one is treated the same as filing late.
Figuring the Right Rate
Ohio’s base rate is 5.75%. Counties and regional transit authorities can add up to 3% on top, so combined rates run as high as 8.75% and vary by location.1Ohio Department of Taxation. Sales and Use Tax Local rates change from time to time, so check the current rate for each place you sell.
Which rate you charge depends on sourcing. Ohio-based vendors selling to Ohio customers generally use origin sourcing, meaning the rate at the location where you receive the order.1Ohio Department of Taxation. Sales and Use Tax Out-of-state sellers and marketplace facilitators use destination sourcing, meaning the rate where the customer receives the goods or service.7Ohio Department of Taxation.

Use tax comes into the same return when your business buys taxable items from a seller who doesn’t collect Ohio sales tax. You self-assess use tax at the same combined rate that would have applied to a taxable purchase.
Filing the Return Through the Ohio Business Gateway
All Ohio sales and use tax returns must be filed electronically. Log into gateway.ohio.gov with your OH|ID credentials and open the sales tax section of your account. The Gateway shows your open filing periods. Pick the correct form and period. Most vendors file the UST-1; businesses reporting use tax file the UUT-1.2Ohio Department of Taxation. UST-1 Data File Upload
Enter your total gross sales, your taxable sales broken down by county, and the tax collected. If you file semi-annually and a county rate changed during the period, the Gateway lets you report both rates on the same return.2Ohio Department of Taxation. UST-1 Data File Upload The system validates your entries and calculates the final amount due, including any vendor’s discount.
Paying and Claiming the Vendor’s Discount
The Gateway takes payment three ways. Electronic check (ACH debit) pulls funds from your bank with no fee. Credit and debit cards are accepted, but the payment processor charges a 2.65% convenience fee (minimum $1) that Ohio does not receive. ACH credit lets you initiate payment through your own bank; that option runs through the Ohio Treasurer of State rather than the Gateway.8Ohio Department of Taxation. Business Tax – Electronic Payments Save the confirmation receipt after you submit; it’s your proof of timely filing.
Ohio applies a vendor’s discount to timely filers at 0.75% of the tax due, capped at $750 per month. The Gateway applies it automatically when you file and pay on time. File late or amend the return and you lose the discount for that period.
Penalties for Filing Late or Underpaying
The penalty for a late return or underpayment is the greater of $50 or 10% of the tax due for the period.1Ohio Department of Taxation. Sales and Use Tax If an audit finds additional tax owed, another penalty of up to 15% can be added. Interest accrues on unpaid balances from the original due date at the rate set under Ohio Revised Code 5703.47. The charges stack, so a return that’s both late and short can get expensive fast.
Records You Keep After Filing
Ohio requires vendors to retain sales tax records for at least four years. That includes invoices, exemption certificates, shipping documents, filed returns with their confirmation numbers, and payment receipts. Food service operators who choose the 14-days-per-quarter sampling option for sales records are still bound by the four-year retention rule.
Keep exemption certificates linked to the transactions they support. When a customer claims an exemption, a valid certificate has to include the purchaser’s legal business name, address, and tax identification number, the reason for the exemption, and a signed date. An unsigned or incomplete certificate offers no protection during an audit.
If You Sell Into Ohio From Another State
Remote sellers cross into Ohio’s tax system once they exceed either $100,000 in gross sales or 200 transactions delivered into Ohio during the current or previous calendar year.7Ohio Department of Taxation. Sales and Use Tax – Substantial Nexus and Marketplace Facilitator At that point, you register for a seller’s use tax license and start collecting and remitting.
If you sell exclusively through a marketplace facilitator such as Amazon, eBay, or Etsy, the platform is responsible for collecting and remitting Ohio tax on sales it facilitates, a rule in effect since September 1, 2019.7Ohio Department of Taxation.
