Change of business

I'm changing my business entirely, totally different market and niche (video and audio editing to interior design). Do I need to let you know that before I fill out my next self-assessment and if so, how/where do I need to do that please? Thanks, Tors

Hi,
 

You can do this on the next Self-Assessment, or you can notify our Self-Assessment department now who can update your record. See link: Self Assessment: general enquiries  . Thank you.
