Employment Status, Naturalisation, Form AN

Hi, I am both full time employed and self-employed at the same time. I am newly self-employed and still waiting for unique tax reference number. As a self-employed person, I have not yet conducted any business and I have not yet completed self-Assessment tax return (my first self-assessment tax return is due next year).

I am applying for naturalization in 3 Weeks’s time. My question is; how should I address my employment status when completing Form AN? I am going to tell Home Office I am both full time employed and Self-employed, but I am not sure for self-employment what documents I should send them. At this stage for self-employment I only have unique tax reference number. For my full time employment I have my Payslips and P60.

Your help is appreciated, thanks.
