HB 4318 allows Oklahoma businesses collecting sales and use tax to deduct a small amount for record-keeping and filing costs. Specifically, it authorizes a 1% deduction on the tax owed (capped at $1,000 per month per business account), but excludes deductions for direct payment permits or late filings (unless due to a declared natural disaster). The bill applies directly to businesses that collect and remit sales/use tax in Oklahoma, covering both the tax calculation process and monthly reporting requirements. It becomes effective November 1, 2026.
