How it works

Tax year: 2026.

Oklahoma taxes income at 2.5% to 4.5%. Enter income before state deductions and choose whether to apply the state standard deduction and personal exemptions, or enter taxable income and switch them off. The tool computes state income tax only; credits other than those named are not applied.

HB 2764 rewrote Oklahoma's schedule for tax year 2026: four brackets and a 4.5 percent top rate (4.75 percent before), with the joint and head of household bands twice the single bands. The standard deduction is frozen by 68 O.S. 2358 at $6,350 single or separate, $9,350 head of household and $12,700 joint for tax years from 2017, with no indexing, and the personal exemption is $1,000 per filer.

Local taxes: Oklahoma cities and counties do not levy a local income tax.
