How to lower your Oklahoma income tax
- Pre-tax retirement savings. Putting $10,000 into a traditional 401(k) on a $75,000 salary cuts Oklahoma tax by about $450 on top of the federal savings.
- Claim state credits. Check the Oklahoma return for earned-income, child, education and renter or property-tax credits that this estimate doesn’t include.
- Watch residency and work location. Days worked in another state and the date you move in or out change how much each state can tax.
- Time large income. Bonuses, stock sales and Roth conversions all land on your state return too.
