TaxYear.uk

TaxYear.uk consolidates the UK fiscal framework into a single, authoritative surface. We engineered a structured registry that tracks personal allowance, banded thresholds, National Insurance, and employer contributions across each tax year — past, present and projected. The build is schema-first, so every figure is anchored to HMRC source data and exposes a clean route for downstream consumers like SalaryGrid and Takehome-Calculator.
