To add VAT, multiply the base by the percentage and divide by 100, then add that amount to the base. To remove VAT from a total, divide the total by 1 plus the rate divided by 100 and round the base to cents; VAT is the difference between the entered total and that base, so the breakdown adds up exactly. Subtracting the VAT percentage from the total would give the wrong base. Always enter the rate applicable to your transaction.
Each tax amount calculated from a base is rounded to the nearest cent; half a cent rounds away from zero. The calculator accepts negative amounts to reflect corrective-invoice arithmetic, but does not determine when a correction is appropriate.
Fictional example: where 21% VAT applies, a €1,000 base produces €210 VAT and a €1,210 total. Working backwards, 1,210 / 1.21 gives a €1,000 base. Correct arithmetic does not mean 21% applies to every activity.
This tool checks arithmetic for one common base. The initial 21% VAT and 15% withholding rates are examples; selecting 0% does not establish that a transaction is exempt or carries no withholding. It does not determine exemptions, reverse charges, IGIC, IPSI, special schemes or the competent tax authority. It neither issues an invoice nor calculates payroll or determines your obligations. If your transaction combines different bases or treatments, check the required breakdown first.
When starting from a VAT-inclusive total with no withholding, the base is rounded to cents and VAT is obtained by difference, so the breakdown adds up exactly to the entered total. When starting from an amount receivable with withholding, rounding VAT and withholding separately can make an exact match impossible; the tool then shows the difference.
