Has your limited company hit hard times?
It is a sad fact of business that many companies fail and the owner/directors lose the money invested in the shares and loans made to the company. The shares in the company become worthless i.e. have negligible value and the owner has made a, sometimes substantial, loss.
Make a negligible value claim
If you are in this situation, you can make a claim to offset the loss against your other income. If you are a higher rate tax payer or have been in recent years, you may receive a tax refund of upto 40% of the loss.
