How this estimate works
The calculator applies the 2026 federal brackets and standard deduction, Social Security and Medicare, and Idaho's 2026 rules to your pay after 401(k) contributions. Head of household filers are estimated with the single-filer state rules. Dependents, tax credits other than personal credits, and some phase-outs for high earners aren't included, so treat the result as a close estimate.
