Oklahoma's 2026 Rewrite
Six brackets became three
House Bill 2764 lowered the top rate from 4.75% to 4.5% and simplified the schedule. For a single filer the first $3,750 of taxable income is now taxed at zero. The next slice, up to $4,900, is taxed at 2.5%, the next, up to $7,200, at 3.5%, and everything above $7,200 at 4.5%. Joint filers get double those thresholds.
The lower steps are narrow. Together they save a single filer about $215 compared with paying 4.5% on everything. Above $7,200 of taxable income, every additional dollar is taxed at 4.5%.
The deduction has not moved since 2017
Oklahoma's standard deduction is fixed at $6,350 for single filers and $12,700 for joint filers. Those were the federal amounts in 2017, and Oklahoma did not follow when the federal deduction roughly doubled the following year. Add a $1,000 personal exemption and a single freelancer shelters $7,350 of income from Oklahoma tax, against $16,100 on the federal return.
More of your profit is taxable in Oklahoma than your federal figures would suggest. On $75,000 of net profit the state bill is $2,591.
More cuts are written into the law
The same bill sets up automatic reductions of a quarter point each time state revenue clears a set threshold, with the long-run aim of removing the income tax. None is guaranteed for a particular year. For 2026, use 4.5%.
Quarterly payments
The Oklahoma Tax Commission expects estimated payments when you will owe $500 or more for the year. No Oklahoma city or county taxes income.
