Who Relies on Ohio Certificate Tracking?
Any Ohio business that makes tax-exempt sales to other businesses, schools, or government agencies.
Wholesalers & Distributors
Selling merchandise for resale requires an active STEC-B on file for every customer account. If a certificate is missing during an audit, you owe the back sales tax plus 15% to 35% statutory penalties.
Industrial Manufacturers
Manage manufacturing exemptions (R.C. 5739.02(B)(42)), packaging equipment exemptions, and direct-use claims across multi-facility Ohio suppliers and sub-contractors.
Commercial Contractors
Construction contractors working on real property projects for exempt entities (schools, hospitals, religious institutions) must retain Form STEC-CO to purchase building materials exempt from sales tax.

Ohio Exemption Certificate Compliance FAQs
Do Ohio sales tax exemption certificates expire?
Under Ohio Revised Code 5739.03, blanket exemption certificates (Form STEC-B) continue in force until or unless revoked by the consumer or vendor. However, Ohio Department of Taxation (ODT) auditors routinely inspect whether the certificate was received in good faith and whether customer business entities remain active. Ohio Sales Tax Pro tracks recommended periodic review cycles (every 3 to 4 years) to ensure your records withstand state scrutiny.
What mandatory elements are required on an Ohio exemption certificate?
Per Ohio Administrative Code 5703-9-03, a legally sufficient exemption certificate must include: (1) vendor name, (2) purchaser name and address, (3) nature of purchaser's business, (4) statutory reason for exemption, (5) purchaser's Ohio vendor's license, tax account number, or active FEIN, (6) signature of purchaser or authorized representative, and (7) date of execution.
What is the Ohio 120-day notice rule in a sales tax audit?
Under R.C. 5739.03(B), when an auditor issues formal written notice of intent to audit, the vendor has a strict statutory window of 120 days to obtain missing exemption certificates or establish that questioned sales were legally exempt. Our platform flags missing or incomplete certificates proactively so you never have to scramble during a 120-day notice clock.
Which Ohio exemption forms does this platform support?
The vault supports all official Ohio Department of Taxation exemption forms: Form STEC-B (Sales and Use Tax Blanket Exemption Certificate), Form STEC-U (Unit Exemption Certificate for single transactions), and Form STEC-CO (Construction Contract Exemption Certificate for real property improvements).
How does Ohio Sales Tax Pro compare to enterprise tools like Avalara CertCapture?
Enterprise systems charge thousands of dollars annually in platform fees, require complex multi-month implementations, and cater to multi-state global enterprises. Ohio Sales Tax Pro is purpose-built for Ohio businesses, enforcing Ohio Revised Code (R.C. 5739) rules directly without bloat, and is 100% free during public beta.
Is customer data and uploaded certificate PDFs secure?
Yes. All certificate documents and purchaser tax IDs are encrypted at rest and in transit. Document storage uses enterprise-grade Row Level Security (RLS) with time-bounded, cryptographically signed access tokens.
