What $100,000 leaves after a year of rent
Rent is the largest single line most workers cannot move, so the take-home gap is only half the story. For states, the rent shown is the average of the metros this site publishes in that state, not a single city.

The same $100,000 under two state tax models
Single filer, no pre-tax contributions, 2026 rules. Taxable income is $83,900 after the $16,100 federal standard deduction and the last dollar falls in the 22% federal bracket — this part is identical in both places. Arizona: Flat 2.50% state income tax. Missouri: Flat 4.80% state income tax.
At this income level, Arizona utilizes a flat 2.50% tax rate, creating a specific deduction from your paycheck. In contrast, Missouri applies a flat 4.80% rate to your earnings. While the federal tax and FICA components remain identical regardless of your residence, the state-level percentage creates the primary divergence in your net pay. The federal system treats your income consistently, yet the state-level tax treatment essentially dictates the immediate gap in your monthly spendable income before accounting for local housing costs.
The net gap between these two states is persistent across the salary steps displayed on this page. As your gross earnings increase from $75,000 to $150,000, the tax discrepancy expands because the flat state percentages apply to a larger total base. This creates a predictable pattern where the state with the higher flat rate consistently reduces your net pay. Because the federal bracket structure and FICA limits remain static, the delta between these regions is driven almost entirely by the state tax math.
Housing expenses act as a counterweight to the state tax variance. While Arizona offers a lower tax burden, the average monthly rent is higher than in Missouri. This creates a situation where the monthly savings from lower tax payments may be partially offset by the higher cost of shelter. When you factor in a year of rent, the gap between the two locations narrows, shifting the advantage depending on whether you prioritize tax efficiency or lower fixed monthly overhead for your housing.

Arizona or Missouri? What it means in practice
This analysis focuses on the 2026 tax landscape for single earners without pre-tax contributions. Beyond state income levies, housing costs fluctuate between these two regions, creating a dynamic trade-off for your monthly cash flow. Whether you prioritize a lower state tax burden or more affordable rental options, the financial trade-offs are specific to your income bracket. Please note that this content is for informational purposes and does not constitute professional tax advice.
In practice, this comparison highlights that lower state taxes do not always guarantee a higher net worth after lifestyle costs. While Arizona may leave more money in your pocket after state tax calculations, the local rental market often reabsorbs a portion of those gains. Workers must evaluate their specific housing needs alongside the annual tax impact to determine which location aligns with their long-term financial goals. A higher nominal salary does not always translate to greater flexibility once rent is paid.
A common mistake involves ignoring the interplay between tax rates and local price indices. Many people focus exclusively on the state income tax, assuming that lower rates automatically signify a more affordable lifestyle. However, housing is often the largest line item for most earners. By viewing taxes and rent as a combined expense, you gain a more accurate perspective on your true disposable income, rather than just focusing on the amount withheld by the state or federal government.
Arizona vs Missouri: common questions
Why is the state tax amount different?
The primary difference stems from the flat tax rates set by each state legislature. Arizona currently imposes a lower percentage on your gross income compared to Missouri. This results in a smaller reduction from your paycheck each month.
Are federal taxes the same in both states?
Yes, because federal income tax brackets and FICA requirements are dictated by national law. Regardless of where you live, these obligations remain constant at $100,000.
Does a lower tax rate always mean more money?
Not necessarily, as rent and other living costs vary significantly. While a lower tax rate increases your net pay, higher local rent prices in one state can offset those tax savings.
How does the net gap change with higher pay?
The gap grows as you move up the salary ladder. Because state taxes are calculated as a percentage of your total income, higher earnings lead to a larger absolute difference between the states.
Should I consider local city or county taxes?
Yes, this comparison covers state-level taxes only. Depending on your specific city or county, you might face additional local levies that further influence your total take-home pay.
Who suits Arizona versus Missouri better?
Arizona often appeals to those prioritizing a lower state tax burden. Missouri may be better suited for those who prefer lower monthly rent costs to keep their fixed expenses manageable.
