Vat z to use for petrol?

Hello there, stef. I'll be happy to share information about VAT (Value Added Tax) in QuickBooks Online.

Please know that the rules on how to tax a product or service can change depending on what you sell and where you sell it. 

In your case, petrol or fuel is a zero-rated supply. Although, the VAT rate is charged at 0%, goods and services classified as 0% or zero-rated VAT are nonetheless subject to taxation. Sometimes the discounted pricing is available only under specific conditions or depending on the customer.

If you’re unsure which tax category to assign, you can ask your accountant for help. They have the best insights into what tax categories your items need. If you don’t have one, you can check our ProAdvisor page to help you find one from there.
