If I am not VAT registered how do I record the VAT that I have paid on purchases for my business? Eg. If I spend £12 on supplies, but £2 of it was VAT does that need to go through as a separate transaction?

Hello Lisa_cotte10-hot, 

Welcome to the Community page,

As far as we are  aware you would record the whole transaction as you cant claim VAT back if you're self employed but you would have to reach out to a trained and qualified accountant if you're not sure, they would be able to advise you on how to record this correctly in your books.
