Ohio Sales Tax Sourcing Rules
Ohio is an origin-sourcing state for in-state retail vendors, with specific statutory exceptions for remote out-of-state sellers, motor vehicles, and lease transactions.
Understanding these rules under Ohio Revised Code § 5739.033 is essential for audit-proof tax collection.

1. In-State Ohio Vendors (Origin Sourcing)
Under R.C. § 5739.033(B)(1): When a vendor with physical nexus in Ohio sells tangible personal property from an Ohio facility, the transaction is origin-sourced to that vendor's location:
"If the consumer receives the property or service at a vendor's place of business, the sale is sourced to that place of business."
Furthermore, when an in-state vendor ships or delivers goods to a customer elsewhere in Ohio, Ohio law treats the vendor's location as the tax situs for in-state vendor licenses.
2. Remote Sellers & Marketplace Facilitators (Destination Sourcing)
Out-of-state businesses that exceed Ohio's economic nexus threshold:
- $100,000+ in annual gross sales, or
- 200+ separate transactions into Ohio
Under R.C. § 5741.05, remote sellers must collect Ohio Use Tax calculated at destination:
- The rate is determined by the delivery address in Ohio.
- If shipping to a split-county ZIP code (e.g.
43003), remote sellers must resolve the exact delivery street address to determine whether Delaware County (7.00%) or Morrow County (7.25%) applies.
3. Motor Vehicle Titling Exception
Motor vehicles, trailers, watercraft, and outboard motors never follow standard retail origin or destination rules:
- Sourced strictly to the buyer's county of residence where the title will be issued.
- Trade-in allowances on new motor vehicles reduce the taxable purchase price prior to calculation.
