Company losses
If your company or organisation is liable for Corporation Tax and makes a loss from trading, the sale or disposal of a capital asset, or on property income, then you may be able to claim relief from Corporation Tax.
You get tax relief by offsetting the loss against your other gains or profits of your business in the same accounting period. You can also choose to carry the loss back, if you do not it will be carried forward to another accounting period.
