VAT rate, zero-rated, and exempt treatment shown on the calculator page.

Calculation methodology

The calculator uses GRA's 15% standard rate and nearest-butut rounding. The 0% treatment fails closed unless the user confirms an export of goods or services and retained evidence. Exemptions are not offered as zero-rated treatments.

Known limitations

  • Informational estimate only. It is not professional tax, legal, payroll, or filing advice.
  • Product classification, exemption, and zero-rating rules can require invoice-level review.
  • Sector-specific, regional, treaty, relief, and special-regime rules may not be fully modeled.
  • Confirm filing, registration, and remittance duties with the official authority or a qualified adviser before submission.

Test-case examples

Input: Net amount: 1,000 at the displayed standard VAT rate.
Expected: VAT equals 1,000 multiplied by the displayed rate; total equals net amount plus VAT.
Why: Confirms the core VAT-exclusive calculation path and makes the rate dependency auditable.

Input: VAT-inclusive amount with the displayed standard VAT rate.
Expected: Net amount equals total divided by 1 plus the rate; VAT equals total minus net amount.
Why: Confirms reverse VAT handling for invoices that already include tax.
