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: Idaho: flat 5.3% state tax with the single-filer standard deduction or exemption; local income taxes not modelled. 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.
