Methodology
Compliance figures are only useful if you can trust where they came from. This page explains exactly how we research, verify, and maintain the data behind every WageHour Tools calculator.
1. Primary sources only
Every rule we encode comes from a primary legal source: the U.S. Department of Labor and individual state labor agencies, EUR-Lex and EU Directives, and provincial or national labor ministries. We do not copy figures from other calculators or aggregator sites. The exact source for each page is linked on that page.
2. Dated verification
Each tool shows the date its figures were last verified against the official source. Minimum wages, salary thresholds, and reporting deadlines change on fixed schedules, so a visible date tells you how current the page is rather than asking you to assume.
3. We mark what we cannot verify
A jurisdiction goes live only when we have verified its rules against a primary source. Where a rule is genuinely ambiguous, contested, or unverified, we mark that jurisdiction “planned” and let you request it — rather than publishing a number we cannot stand behind.
4. Estimates are labelled as estimates
Some results — such as daily-overtime stacking or an unadjusted pay gap — are estimates that depend on inputs we cannot see (your full timesheet, role-level pay controls). We label these clearly and explain what a final, audited calculation would account for.
5. Corrections welcome
If you find a figure that is out of date or a rule we have read wrong, tell us. We review every correction against the official source and update the page and its verification date.
Not legal advice
Our methodology is designed for accuracy, but WageHour Tools still provides general information and estimates only — not legal, tax, payroll, or financial advice. For decisions, consult a qualified professional alongside the official sources we cite.
