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: California: 2026 rates on the latest published (2025) bracket widths. State indexing pending. California: 2025 bracket widths (FTB publishes 2026 in Oct); includes the 1% surtax above $1M and the uncapped 1.3% SDI as a separate line; exemption-credit phase-out above $252k AGI 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.
