Frequently asked questions
How much are taxes on $45,000 in Missouri?
$7,840 in total for 2026: federal income tax, Social Security and Medicare, plus $1,178 of Missouri state deductions.
What assumptions does this page make?
Tax year 2026 annual view (not W-4 withholding), single filer, standard deduction, no dependents, no pre-tax benefits. State notes: Missouri: Standard deduction matches federal. The small capped federal-tax deduction is not modelled (slightly overstates MO tax at low incomes); KC/St. Louis 1% earnings taxes not included. See the US methodology.
Why do other sites show a different number?
Most mix per-paycheck withholding with annual liability, or silently skip state mechanics. We state the model: annual 2026 liability, with every state assumption listed above.
