Oklahoma Income Tax Calculator (2026 Filing Season)
Oklahoma 2025 brackets: 0.25%–4.75%, depending on income and filing status.
Brackets are so compressed that nearly everyone pays the top 4.75% marginal rate.
We subtract Oklahoma's standard deduction ($6,350) automatically.
The same $75,000 income in a no-income-tax state (Texas, Florida, Tennessee…) would owe $0 in state income tax — a difference of $3,072 per year.
We only store your state and filing status — never your income.
