Source hierarchy
- Primary federal sources come first: IRS forms, instructions, publications, topic pages, and official news releases.
- SSA guidance is used for Social Security wage-base figures.
- For state planning references, QuickTaxTools prefers official state revenue department guidance. Where that is not practical in a lightweight snapshot tool, the page explicitly states its narrower scope.
Calculator review approach
Each calculator is built around the formulas and limits it visibly displays. The goal is to keep the logic transparent: users should be able to see which tax year is covered, which thresholds are in play, and which assumptions are being made before they rely on an estimate.
When a calculator can only support a planning snapshot, the page says so directly. The state tax tool is the clearest example: flat-tax and no-tax states are easier to estimate directly, while progressive-state outputs are intentionally labeled as marginal-range planning help instead of full-return precision.
Update cadence
- Annual tax-law and inflation updates are reviewed when the IRS and SSA publish new limits.
- Pages display an updated date and link the primary source set used for the current version.
- Trust pages, methodology notes, and the source library are refreshed when calculator logic or scope changes.
Quick access
Core trust and support pages live here, while every calculator stays linked from the main directory on each tool page.
