Bed and breakfat rules

If you buy and sell the same shares on the same day inadvertantly (due to inexperience without any intent to avoid tax) breaking the bed and breakfast rules of buy and selling the same shares on the same within 30 days what are the potential consequences/associated fines for this action. I am struggling to find this out. Also if the CGT is the allowance anyway and the purchase/selling of the shares results in loss within this be significant?

Hi,
Please refer to the link below for guidance:
CG13360 - Bed and breakfasting: conditions to be satisfied
Thank you

The official guidance is not very clear to non-accountants. Firstly it is not at all illegal to buy back shares, so long as you follow the b&b rules when declaring gains/losses. I believe the way to do this is to transpose the relevant costs, ie when you sell for the first time you assume that the shares were purchased at the NEW price rather than the acquisition price, and when you sell for a second time you assume that the shares were purchased at the ORIGINAL cost. (I do not pretend to be an expert, but have myself struggled with this issue and I am fairly certain that I have go it right now!)
