I do not earned more than £7500 per year from Room rent. Does "Added Tax" is applicable for me In Liverpool, UK? If is it which option I have to select and what is percentage? Please help. Thanks
What added tax are you referring to @Mohammad128
The rent a room scheme is a UK government tax scheme and nothing to do with Airbnb.
I am in a similar situation to you and am not aware of any tax that you need to add to your listing.
