Summer’s winding down, but the sales tax calendar isn’t slowing down with it. August brings a wave of back-to-school sales tax holidays in states like Arkansas, Florida, Texas, and Virginia—which means more exempt transactions to track alongside your regular filing obligations.

To make things easier, we’ve put together this state-by-state overview of August 2026 sales tax due dates, including any sneaky shifts due to weekends.

Note: Due dates have been adjusted based on each state’s weekend and holiday filing rules. Businesses should always verify filing requirements directly with the appropriate state tax authority.
