Standard vs Flat Rate scheme
Under the Standard scheme, you charge 20% VAT on sales (output VAT), reclaim VAT on business purchases (input VAT), and pay HMRC the difference. Under the Flat Rate scheme, you pay a fixed percentage of your gross (VAT-inclusive) turnover and generally cannot reclaim input VAT — simpler admin, and sometimes cheaper for service businesses with low costs.
