No. Oklahoma subtracts all Social Security benefits included in federal AGI on Schedule 511-A.

Yes: Oklahoma offers the Oklahoma Earned Income Tax Credit, 5% of the federal EITC (refundable). Calculated under federal EITC rules as they stood in tax year 2020 (Form 511-EIC). Prorated by the ratio of Oklahoma AGI to federal AGI. Refundable since tax year 2022.

Only instead of income tax: itemizers in Oklahoma pick sales tax (4.5% state rate, about 9.06% with local taxes) or state income tax, whichever is bigger. The 4.5% state sales tax on groceries was eliminated Aug. 29, 2024; local sales taxes still apply to food.

Yes on your federal return if you itemize, within the $40,400 SALT cap. Oklahoma adds its own break: property tax relief credit (538-H) up to $200 for 65+ or disabled heads of household with income of $12,000 or less.

No: Oklahoma doesn't offer a renter's credit or rent rebate. Oklahoma has no state tax credit or rebate specifically for renters; its property tax relief claim (Form 538-H) is for homeowners. Renters can still claim the Sales Tax Relief credit (Form 538-S), $40 per qualified exemption, with household income of $20,000 or less, or $50,000 or less if they have a dependent, are 65+, or are disabled. Lower-income renters can still claim Oklahoma's earned income credit: 5% of the federal EITC.

No: Oklahoma doesn't base registration on your car's value, so it isn't deductible as personal property tax. Annual fee runs $96 (years 1-4) down to $26 (year 17+) in lieu of property tax; it is age-based, not value-based.

For 2026 Oklahoma taxes the first $3,750 (single) / $7,500 (MFJ/HoH) at 0%, then 2.5% and 3.5%, with a 4.5% top rate above $7,200 (single) / $14,400 (MFJ/HoH), down from 4.75% (HB 2764).

Yes on your Oklahoma return: $10,000 single / $20,000 joint per return. Only contributions to the state's own plan count. OK 529 plans only; contributions and rollovers through April 15 (or return due date) can be deducted for the prior year.

Yes: Child Care/Child Tax Credit: the greater of 5% of your federal child tax credit (including the refundable portion), worth about $110 per child, or 20% of your federal child care credit. Only if federal AGI is $100,000 or less. Nonrefundable, and prorated by the ratio of Oklahoma AGI to federal AGI.

Yes, as a business expense: Oklahoma charges $100 to form an LLC; ongoing: $25 annual certificate. Due on the formation anniversary date (60-day grace period); online card payments add a 4% fee.
