s 84 How relief works
This section explains how the deductions are to be made. The amount of the unrelieved loss to be deducted at any step is limited in accordance with section 25(4) and (5). Step 1 Deduct the unrelieved loss from the profits of the trade of the next tax year. Step 2 Deduct from the profits of the trade of the following tax year the amount of the unrelieved loss not previously deducted. Step 3 Continue to apply Step 2 in relation to the profits of the trade of subsequent tax years until all the unrelieved loss is deducted.
