Value Added Tax (VAT) is often seen as a headache, but for some IT contractors and consultants, it can actually generate profit.
Designed to simplify VAT for small businesses (turnover under £150k).
On £100,000 turnover, this "VAT Surplus" is £2,600 of pure extra profit.
If you spend less than 2% of turnover on goods (software/services don't count), you are a "Limited Cost Trader".
You cannot use a spreadsheet and type figures into the HMRC website anymore. You must use MTD-compatible software (Xero, FreeAgent, QuickBooks) to file quarterly returns.
Disclaimer: VAT rules are rigid. Late filing penalties are automated.
