Re: I need my food expenses to be 100% deductable as a business expense. Quickbooks selfemployed ...
You'll need to speak to an accountant, about the right way of going about this. When you fill in your Self Assessment, you can just combine the allowable and dis-allowable columns, however this would not match what is on your books.
On QBSE, Meals and entertainment will always be disallowable, whereas advertising will be allowable, and that posts to the according box on the SA103F
