UK rate card
GET /v1/uk/rates returns a single JSON object with headline 2026/27 figures: VAT rates, income tax bands, NI percentages, minimum wage rows, HMRC mileage, ISA allowance, pension annual allowance, and residential SDLT slices.
This is a static snapshot assembled from published GOV.UK and HMRC rates. It is not a live HMRC lookup. Always confirm on GOV.UK before filing.
