I bought an Apple Watch Series 4 shortly after they came out last month and it's been great! I'm going to be selling my other Garmin watch I used to use - however I was given that as a gift, so no matter how much or how little I make it will be profit. But is that money taxable or not? I've tried to figure it out but just can't - got some numbers from this tax calculator (
https://salary-calculator.org.uk/
) but not sure if they're right or not - any advice?
Cheers! :)
