Hi, I have just started airbnb and letting the furnished room on my property. Airbnb just asked my National insurance number so they can tell my earning at the end of financial year. Question arises over here 1. If I tell them my NI number, will the income be added in my PAYE and my tax bracket will increase? 2. If it is added in my PAYE then my tax code will be change? 3. How I can tell HMRC that I come under rent-a-room scheme and how that will work with my PAYE?
