AfterTaxLabMoving from Missouri to Arizona: $100,000 After Tax
Transitioning from Missouri to Arizona involves adjusting to different state revenue structures. For a single filer earning $100,000, the primary change occurs within the state income tax column of your payroll. While your federal obligations and FICA contributions remain consistent regardless of your geography, the state withholding shifts to reflect the Arizona tax policy. This page provides a breakdown of how these specific modifications influence your net pay, assuming no pre-tax contributions are made during the 2026 tax year.
Flat 4.80% state income tax
Take-home after a year of rent: $56,548 (17.8% of gross goes to rent)
Flat 2.50% state income tax
Take-home after a year of rent: $57,444 (19.2% of gross goes to rent)
At $100,000 the same federal brackets and the same FICA apply on both sides, so the whole difference comes from the state line and the rent. Missouri takes $4,800 in state tax, Arizona takes $2,500 — take-home moves from $74,380 to $76,680. Adding the annual rent difference ($117 a month at the rents published here) leaves an annual gain of $896, about $75 a month.

The same $100,000, two state tax treatments
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 — identical on both sides of the move. Missouri: Flat 4.80% state income tax. Arizona: Flat 2.50% state income tax.
The tax landscape shifts significantly when you cross the border into Arizona. Missouri applies a flat tax rate to your income, which represents a larger portion of your earnings compared to the Arizona flat rate. On a $100,000 salary, this reduction in the state tax burden provides an immediate increase in your periodic take-home pay. Since federal income taxes and mandatory FICA withholdings are based on federal guidelines, those portions of your paycheck stay identical before and after your move, ensuring the tax relief remains isolated to the state level.
While the state tax reduction provides an advantage, the cost of housing often offsets part of these savings. Moving to the average Arizona metro area typically increases your annual rent bill compared to the Missouri average. This housing gap acts as an effective tax, consuming a portion of the relief gained from the lower state rate. When you combine the tax savings with the higher cost of rent, the net annual gain is reduced to $896. Monitoring these two factors together is essential for an accurate projection of your disposable income.
The salary ladder provided on this page demonstrates that the gap between these states scales predictably with your earnings. Because federal taxes and FICA are constant across both states, they create a shared floor for your net pay. The ladder shows that at lower salary tiers, the tax savings are narrower, while at higher tiers, the tax savings grow more pronounced. Regardless of your bracket, the federal portion remains static, ensuring that the primary variance in your total annual compensation is driven by the state tax difference and local living costs.

Moving from Missouri to Arizona: what it means in practice
This analysis is not tax advice and is intended for informational purposes only. Moving between these states shifts more than just your tax rate, as housing costs typically vary across state lines. By comparing the state-level tax burden against the differences in average monthly rent, you can better understand how your annual take-home pay is affected. We examine these variables at various income levels to illustrate how your specific salary influences the total financial outcome of your relocation.
This move generally suits professionals looking for a lower state tax environment, provided their housing choice aligns with their budget. It may be less advantageous for those who rely strictly on the state tax savings to offset substantial increases in lifestyle expenses. Since the rent difference consumes a portion of the tax gain, individuals who secure housing below the average market rates found in Arizona will see the most significant financial benefit. Conversely, those moving into high-end rental markets may find that the net monthly gain is minimal.
Before finalizing your relocation, verify the residency requirements for both states to avoid dual taxation. Ensure your employer adjusts your payroll withholding to the new state promptly to prevent potential end-of-year tax filing issues. It is also wise to investigate local municipal taxes, which can vary by city and impact your final take-home amount beyond what the state-level figures suggest. Finally, compare your actual rental prospects against the published metro figures to ensure your personal cost of living aligns with these broader state averages.
