VAT Flat Rate calculator: use VAT-inclusive turnover
Apply the selected HMRC rate to VAT-inclusive turnover and keep standard-accounting inputs separate.
Decision boundary
The scheme payment is the applicable flat rate multiplied by VAT-inclusive turnover. This comparison does not select your trade sector or approve scheme use.
Evidence to check
- VAT-inclusive turnover for one return period
- Applicable HMRC sector or limited-cost rate
- First-year discount window
- Standard-accounting figures from the same period
