- W-2 earners across Oklahoma City, Tulsa, Norman, Edmond, Broken Arrow
- Oil and gas industry workers, trades, and manufacturing employees
- Contractors, freelancers, and small business owners
- Real estate investors and landlords
- Short-term rental hosts
- Families with children
- Retirees drawing taxable income
- Dual-income households
Below is a complete Oklahoma-focused summary of the 2026 tax law changes.
Key Federal Changes Affecting Oklahoma in 2026
Standard Deduction Shrinks
The enhanced standard deduction from TCJA expires in 2026. OBBBA does not extend it.
- Single: ~$8,300
- Married Filing Jointly: ~$16,600
- Head of Household: ~$12,400
This significantly increases federal taxable income — and because Oklahoma uses federal AGI as the starting point, state taxable income rises too.
Federal Tax Brackets Increase
- 12% → 15%
- 22% → 28%
- 24% → 31%
- dual-income families
- oilfield workers with high overtime
- teachers, nurses, and state workers
- contractors and trades
- households earning $50K–$200K
Higher federal tax liability increases the amount of income taxed at the Oklahoma state level.
QBI Deduction Made Permanent Under OBBBA
OBBBA permanently preserved the 20% Qualified Business Income (QBI) deduction for:
- LLCs
- S-Corps
- sole proprietors
- contractors
- freelancers
- qualified rental operations
However, new QBI thresholds, wage rules, and documentation requirements begin in 2026.
Oklahoma does not apply a matching state-level QBI deduction.
Child Tax Credit Shrinks
- Federal Child Tax Credit decreases from about $2,000
- To roughly $1,000 per child
- Refundability is reduced
Families in Oklahoma City, Tulsa, and suburban areas will notice reduced refunds.
Marriage Penalty Returns
TCJA temporarily eased the marriage penalty, but OBBBA allows it to expire.
- married couples reach higher brackets sooner
- credit eligibility is reduced
- joint incomes push federal AGI up
- Oklahoma state taxes increase as a result
Dual-income households will feel this most.
Oklahoma–Specific Tax Considerations
1.Oklahoma Uses Federal AGI to Calculate State Taxes
Because Oklahoma’s state tax is based on federal AGI:
- higher federal taxable income
- fewer federal deductions
- reduced federal credits
…all directly increase Oklahoma state taxable income.
This impacts many Oklahoma families, especially in metro areas.
2.Oil & Gas Workers Are Strongly Impacted
Oklahoma’s workforce includes a large number of employees in:
- oil and gas extraction
- pipeline and refinery operations
- energy support services

Federal bracket increases magnify tax liability on this type of income.

5. Retirement Income Planning Is More Important Than Ever
