Marking payments as personal which are paid into the business account.

Hi,

This is a question about marking payments into my bank account as personal, non-business payments.

I'm going through my accounts explaining transactions and as I've only recently opened a Business Account, there are a mixture of business and personal transactions within this older account.

I was given £500 as a gift from my father and I'm wondering what to mark the payment as so I'm not taxed on it?

Thankyou,
James
