  3. Consider domicile — the Texas border is nearby (no income tax)
  4. Itemize if beneficial — may exceed standard deduction
  5. Capital gains timing — taxed as ordinary income
  6. HSA contributions — triple tax advantage at the federal level

Bottom Line

Oklahoma has progressive income tax rates from 0.25% to 4.75%, with the top rate applying to relatively low income levels. The state offers a retirement income exclusion and largely exempts Social Security. Confirm current combined sales tax rates, which have historically been high in some areas. Property taxes are below average. Texas (no income tax) borders Oklahoma, making location decisions tax-relevant.
