Why use a multi-line VAT calculator?

Single-amount VAT tools are useful for a quick price check, but an invoice often contains several products or services. This tool totals each line as quantity × unit price, calculates VAT per line, and adds the subtotal, VAT total and grand total.

Use country rates carefully

The country selector is a starting point, not a tax-jurisdiction decision. A supply can be zero-rated, exempt or subject to another treatment. Check the linked authority source and local invoice rules before sending a document to a customer.

Frequently asked questions

Can each invoice line use a different VAT rate?

Yes. Each line has its own editable VAT rate, so you can separate standard, zero-rated or other rates when the applicable rules allow it. Verify the classification before issuing an invoice.

Does this create a legally compliant tax invoice?

No. It calculates line totals and VAT estimates in your browser. It does not generate an official tax document, determine tax liability or replace local invoicing requirements.

Which countries are supported?

The calculator starts with KIDDOO's reviewed country profiles, including Thailand, Kenya, Nigeria, Bangladesh, Uganda, Tanzania Mainland and Nepal. You can edit the rate, but the selected country's source and limitations remain visible.
