FAQPage Schema
How do I calculate Ohio Commercial Activity Tax liability from gross receipts?

Calculate Ohio CAT liability by applying a 0.26% tax rate to Ohio-sourced gross receipts exceeding the $6,000,000 exclusion threshold. The calculation requires identifying Ohio-sitused receipts and subtracting the exclusion amount before applying the rate.

When do I need to file Ohio CAT quarterly returns?

Ohio CAT quarterly returns are due on the 10th day of the second month following the quarter-end. You must file quarterly once your Ohio gross receipts exceed the $6,000,000 threshold and establish bright-line nexus.

What are bright-line nexus and situsing rules for Ohio CAT?

Bright-line nexus for Ohio CAT is triggered when gross receipts from Ohio sources exceed the statutory threshold. Situsing rules determine which receipts are attributed to Ohio based on where the revenue-generating activity occurs for accrual purposes.

Does Ohio CAT apply to multi-entity ownership groups?

Ohio CAT enforces ownership aggregation for multi-entity owners, meaning combined gross receipts across commonly owned entities are tested against the $6,000,000 exclusion threshold to determine overall tax liability.

How do municipal tax overlays affect Ohio CAT in Columbus, Cleveland, and Cincinnati?

Municipal tax overlays in cities like Columbus, Cleveland, and Cincinnati are factored into the overall Ohio CAT calculation to account for additional local tax obligations beyond the state-level commercial activity tax.

What is the Ohio CAT gross receipts exclusion threshold?

The Ohio CAT gross receipts exclusion threshold is $6,000,000. Receipts at or below this amount are excluded from the 0.26% tax, meaning only the portion of Ohio-sourced gross receipts above this threshold is taxed.
