Income tax; providing credit for certain miles commuted to workplace. Effective date.

SB 342 creates a refundable income tax credit for Oklahoma individual taxpayers who commute at least 2 miles each way (4 miles total daily) to a fixed workplace where they reside year-round. The credit amount is calculated by multiplying 240 (days) by the daily commute miles (max 40 miles) and the IRS standard mileage rate for that year. If the credit exceeds the taxpayer's income tax liability, the excess is refunded directly. This bill directly affects employees commuting regularly to a single workplace within Oklahoma, providing a concrete tax benefit based on actual commute distance.
