Ohio UST-1 Sales Tax Filing FAQs

When is the Ohio UST-1 sales tax return due?

Under Ohio Revised Code 5739.12, monthly UST-1 sales tax returns and payments are due on or before the 23rd day of the month following the close of the reporting period. If the 23rd falls on a weekend or state holiday, the deadline moves to the next business day.

What is the Ohio timely filing vendor discount?

Vendors who file their UST-1 return and pay the full tax liability on or before the 23rd of the month are entitled to a 0.75% discount on the total tax collected (R.C. 5739.12). Late returns forfeit this discount entirely and incur statutory late fees ($50 or 10% penalty).

How does the assistant handle Ohio origin vs destination sourcing?

Per R.C. 5739.033(B)(1), in-state sales by Ohio vendors are origin-sourced to the location where the vendor receives the order (regardless of ship-from location), while remote out-of-state sellers and marketplace facilitators follow destination sourcing under R.C. 5741.05. Ohio Sales Tax Pro automatically applies the correct statutory sourcing rule to each transaction.

Can I import CSV exports from Shopify, Square, Stripe, or QuickBooks?

Yes. The filing assistant accepts standard transaction exports from major e-commerce carts and accounting platforms, parses taxable vs exempt amounts, and aggregates transactions into the exact county schedules required by the Ohio Business Gateway.

Does this file the return automatically with the state?

During our public beta, Ohio Sales Tax Pro prepares the exact county-by-county allocation schedules, lines, and figures so you can copy/paste or key them directly into the Ohio Business Gateway or OH|TAX portal in under two minutes without math errors.

Is there any cost to use the filing assistant?

No. The UST-1 filing prep assistant is 100% free with no credit card required throughout the Ohio Sales Tax Pro public beta.
