6 tax brackets from 0.25% to 4.75%
At $100,000 income, Oklahoma charges 4.75% marginal state income tax, resulting in approximately $4,679 in state tax burden. Oklahoma has one of the lowest state income tax rates with 6 progressive brackets from 0.25% to 4.75%. The top rate applies to income over just $7,200, making it effectively a near-flat tax for most earners.
Oklahoma has a low progressive income tax with rates ranging from 0.25% to 4.75% across 6 tax brackets. While technically progressive, the top 4.75% rate applies to all income over just $7,200, making it effectively a flat tax for virtually all working adults. This makes Oklahoma one of the most tax-competitive states in the nation.
Why these rates? Oklahoma's economy is historically tied to oil and gas production, which generates substantial state revenue through gross production taxes and corporate taxes. This allows the state to maintain lower income taxes than most states while funding government operations. Tulsa and Oklahoma City have become tech and aerospace hubs (American Airlines, Boeing, Devon Energy).
How it compares:
Recent changes: Oklahoma has been gradually reducing its top rate. In 2021, the top rate was 5%. It dropped to 4.75% in 2022 and has remained there through 2026. State lawmakers continue discussing further cuts to match neighboring Texas (0%), but oil price volatility makes large cuts politically difficult.

Key insight: Moving from Oklahoma to Texas saves $4,679/year at $100K income, $7,054/year at $150K. However, Texas property tax is significantly higher.
The total picture:
Oklahoma's income tax ranges from 0.25% to 4.75% across 6 progressive brackets. However, the top 4.75% rate applies to all income over just $7,200, meaning almost all working adults pay the maximum rate on the vast majority of their earnings. This makes it effectively a flat 4.75% tax. The effective rate for a $50K earner is about 4.5%, and for $100K earners it's 4.7%.
Oklahoma has 6 tax brackets: 0.25% ($0-$1K), 0.75% ($1K-$2.5K), 1.75% ($2.5K-$3.75K), 2.75% ($3.75K-$4.9K), 3.75% ($4.9K-$7.2K), and 4.75% (over $7.2K). The narrow brackets mean you hit the top rate almost immediately. For example, someone earning $50,000 pays 4.75% on $42,800 of that income - nearly 86% of their total earnings.
Oklahoma: $4,679 state income tax at $100K. Texas: $0 income tax. Texas saves $4,679/year on income tax alone. However, Texas property tax averages 1.60% vs Oklahoma's 0.90%. On a $400K home, Texas charges $6,400/year property tax vs $3,600 in Oklahoma - a $2,800 difference. Net savings moving to Texas: $1,879/year at $100K income. The gap widens for higher earners but narrows for homeowners with expensive properties.
No, Oklahoma does not tax military retirement pay at all. This makes it highly attractive for military retirees compared to neighboring states that do tax it. For example, a retiree with $50,000 military pension pays $0 in Oklahoma vs $2,375 in Kansas (4.75% effective rate). Combined with low cost of living (median home $187K), Oklahoma is becoming a popular retirement destination for veterans, particularly near Tinker AFB.
Move if: you're relocating from high-tax states like California ($5,000-15,000/year savings depending on income), seeking very low cost of living (median home $187K), work remotely (tech/aerospace jobs growing), military retiree (no tax on retirement pay), or prefer space and no traffic. Stay away if: you can move to Texas for 0% income tax (saves $4,679/year at $100K), need major city amenities (OKC/Tulsa are mid-size), concerned about weather (tornadoes), or prioritize high salaries (OK pays 10-20% less than coastal cities).
