About

UK VAT Flat Rate Calculator works out what a small business would pay under the HMRC VAT Flat Rate Scheme and how that compares with standard VAT accounting. list_frs_categories and lookup_frs_rate return the flat rate percentage of the GOV.UK table for a trade category, choosing the dated row for catering, hotel and pub businesses (whose rates changed on 15 July 2020, 1 October 2021 and 1 April 2022) and showing the 1 percent first-year discount when a VAT registration date is supplied. compute_frs_payment applies the percentage to VAT-inclusive turnover. limited_cost_trader_test tests goods spend against 2 percent of turnover or GBP 1,000 a year and returns the 16.5 percent limited cost rate when it applies. compare_standard_vs_flat sets output minus input VAT against the flat rate result for a period, and joining_limit_check compares expected turnover with the GBP 150,000 joining figure. frs_reference returns every figure with its GOV.UK source, retrieval date and verification label. All arithmetic is exact decimal and local; nothing is stored, submitted or filed. General information only, not tax advice.

Sources: Reference data from official sources (gov.uk); every answer states its source, date and validity period.
