Hi! I have a quick simple question I was hoping someone here could answer - I buy and sell goods on eBay and was wondering. I arrange shipping myself so all money from the sale, including shipping, goes into my bank, and then a chunk comes out for shipping (next day, so usually around £5-10 depending on size). As far as I am aware I am paying income tax on all of the money from the sale - so can I claim shipping as a business expense or something similar, or not declare it as income even though the money has come through my bank? Looking at this salary tool it would certainly save some money. I'm not totally sure how it works and could use some advice. EDIT: I say it's a simple question, that's ended up quite a big post Thanks in advance to any replies!
