Federal tax
IRS materials inform withholding structure, standard deduction framing, and other federal payroll references used across the site.
Sources
Payroll and tax source hub
This page groups the main source categories used to support calculator copy, state guides, payroll resource pages, and trust content.
Payroll programs
Federal and state agency materials inform references to unemployment, leave, disability, wage floors, and payroll administration context.
State authorities
State guide and payroll resource pages are the main place where state agency context is attached to calculators and supporting notes.
Federal reference categories
State-specific authority links should live closest to the state guide or payroll resource page where the context is explained, rather than being hidden inside a generic national page.
As top-state pages are upgraded, they should expose more direct source links alongside assumptions, examples, and local payroll nuance.
