HB 3314 allows Oklahoma counties to impose a local tax of up to 15% on retail marijuana sales (not personal cultivation) after voter approval. Counties must hold a special election or use an initiative petition (requiring 5% of registered voters' signatures) to approve the tax, with results requiring a majority vote. Funds collected must be used exclusively for public safety (sheriffs, police, fire departments) and property improvements, and counties must specify the tax's purpose and duration to voters. The Oklahoma Tax Commission will handle tax collection for a 0.5% fee, and counties must provide 60 days' notice before rate changes. The bill takes effect November 1, 2026.
