Site-wide content + schema review across all 18 calculators
Verified sources, formulas, FAQs, and Key Concepts across every Phase 1 and Phase 2 calculator. Refreshed lastReviewed dates, expanded FAQs from 5 to 10 per calc, and added Common-mistakes + When-to-use prose to all four topic clusters. JSON-LD now emits Person, dateModified, and HowTo on every calc and variant page.

Current per-calculator review dates
The date each calculator was most recently reviewed against primary sources (IRS, HMRC, SARS) and its own formula documentation.
Update cadence
Tax rates are reviewed every 12 months or whenever a region changes its headline rate. Interest-rate benchmarks (SBA, BoE, SARB) are reviewed quarterly. Articles are reviewed annually. See the editorial policy for the full standards we hold every page to.
