Frequently asked questions about VAT
Why doesn't a 0% rate mean VAT-free?
A 0% rate still applies VAT law to the transaction — it's typically used for exports and certain other qualifying sales, and the seller must still report it. "VAT-free" or "exempt" means VAT doesn't apply to the transaction at all, which is a different legal category.
What is a VAT return?
A VAT return is the periodic report a VAT-registered business files with its tax authority, showing the VAT it has charged customers and the VAT it has paid on its own purchases.
What is VAT in simple terms?
VAT is a tax added to the price of most goods and services. The buyer pays it to the seller, who then passes it on to the tax authority.
How do I deal with a supplier that doesn't charge VAT?
If a business isn't VAT-registered, its invoices and contracts should clearly state that the price excludes VAT. No VAT reporting is required for that transaction on your end.
How can I tell if a business charges VAT?
Check the business's invoice, contract, or registration details — a VAT-registered business is required to show its VAT number on invoices, and you can usually verify registration through your country's tax authority.
How do I correct a VAT return I've already filed?
You'll need to submit an amended VAT return to your tax authority along with an explanation of the correction. The exact process varies by country, so check your local tax authority's guidance.
