I am not VAT registered. When entering expenses and invoices do I enter net value exclusive of VAT or gross values inclusive of VAT? do I set VAT to zero?

Hi user35694,

Selecting Inclusive of VAT must be used for VAT registered company. It means that there will be taxes added on goods and services depending on the VAT codes. 

For non-VAT registered businesses, you can select the Exclusive of VAT for your sales and expenses. There's no need to set up a zero VAT rate. 

Please refer to this UK website to learn about which services marked as No Vat: https://www.gov.uk/vat-businesses/inclusive-exclusive-prices.

On the other hand, when the business is a fully VAT registered, please follow the steps in this article on how to set up the VAT codes and rates: Set up and edit VAT settings, VAT codes and VAT rates.

We are glad we're able to help you decide which VAT code to choose for your transactions. Keep us posted if you've got more questions.
