What these numbers mean
  • The big number is the tax to put aside each month: the tax inside your sales minus the tax you paid on purchases.
  • Tax inside those sales is worked out from sales that already include tax at the rate you entered.
  • Total ready by the due date is that monthly amount times the months in your tax period. It helps your cash flow.

Good to know

  • This is general only and not tax advice. Rules, rates and what you can claim differ between countries and businesses.
  • It assumes every sale is taxed at the one rate you type. Tax-free or exempt sales should be left out of the sales figure.
  • Sales and purchases are treated as the same every month. If yours go up and down, use an average or run it month by month.
  • This is a guide only, not a quote, an offer of finance, a borrowing limit or financial, legal or tax advice.
