Ebay sales

I am a self employed joiner and complete self assesmnt tax return annually, However I am selling various things on ebay, some items are personal from my house and off my cars and bike parts etc, but some are items which I have acquired from jobs I have done , stripped for parts and sold, ie profit.I have never actually bought anything with intent to sell, just accumulayted things for free, all the cash earned from these goes into a different bank account to my buisness, and I buy personal items on ebay using these funds, so never actually see the cash)...So how do I differentiate the personal tems if i do a self asssement . ans aso can i do a separate self assesment tax return for the ebay to my buisness..

Hi,

Self Assessment is used to declare your worldwide income, not just self employment. There are other supplementary pages to cover areas not included in the main tax return.

You pay Capital Gains Tax on the gain when you sell, or ‘dispose of’, most personal possessions worth £6,000 or more, apart from your car, unless you have used it for business. Possessions can be jewellery, paintings, antiques, coins and stamps and sets of things, such as matching vases or chessmen. These are just some examples.  

Using the proceeds to buy more assets, would only impact the gain, and, or loss arising from the disposal of those assets, when they are disposed of.  

HMRC cannot provide a definitive answer as, under Self Assessment, HMRC does not generally provide clearance on how individuals should declare their income or gains. It is instead the customer's responsibility to assess the available guidance and arrive at their own considered conclusions. 

Thank you.
