Once or twice a month?
That's trading, 90% for sure I'd say. You'll be subject to income tax on the profits.
A few questions:
1) What is it you're selling?
		
		
	 
I buy crap cars which are damaged. And as a hobby I end up fixing them. I have a friend who is a mechanic who helps me out, so it's kind of labour for free. Now, i've found out that the cars I have purchased are worth more than what I got them for after I have fixed them up! So, I was thinking of buying, reparing, selling. We repair in my friends shop/garage which is closed on weekends to customers but me and my friend use the facilities there and close the shop shutters behind us.
	
		
	
	
		
		
			2) Are you selling it with the intention of making a profit?
		
		
	 
It's more of a hobby, but yes, the intention of making a small profit.
	
		
	
	
		
		
			3) Are you enhancing the asset prior to sale?
		
		
	 
I think that's a yes as I buy them damaged and thinking of selling them undamaged.
	
		
	
	
		
		
			4) Will you be "enjoying" or making use of the asset between acquisition and sale?
		
		
	 
No, because I wouldn't be insured on the car. And neither would my mate meaning we wouldn't be legally allowed to drive it. The only joy we get is fixing the cars and learning more about them on the way of fixing them.
	
		
	
	
		
		
			5) How are you financing your purchases?
		
		
	 
It's all out of my own pocket. The money to buy the broken up car and it's parts are financed by my weekend job (which is taxed! 

 )
	
		
	
	
		
		
			PS I'm a trainee tax adviser.
		
		
	 
Beautiful, is it a good job?
I hope that makes things a little clear for people and sorry for being vague. For a reason im not too sure about I was reluctant to give loads of information out. I must stress, so far, we haven't sold a single car yet. And if we do, it'll be about 1 car, maybe 2, per 1/2 months.
