How to enter multiple trade profits and losses on the CT600?

Unfortunately, you cannot complete more than one trade computation within the CT600.

To report the profit/loss amounts separately, you will need to complete the one computation but can separate out the profit and loss amounts by following the steps below. A PDF computation for each trade can then be attached to the return.This can be done in either SimpleStep or HMRC Forms mode:

SimpleStep mode

1. Go to CT600 Core > Trade and professional income > Tax adjusted profit/loss – disallowable expenditure.
2. Enter one of the trades' profit or loss in the box labelled Profit/(loss) on ordinary activities before taxation. Then:
   • To declare a separate trade profit, enter the amount in the box labelled Other expenditure not analysed above – click on the wizard icon to enter a description of the profit (for example, profits from second trade).
   • To declare a separate trade loss, Go to CT600 Core > Trade and professional income > Tax adjusted profit/loss - other adjustments > Miscellaneous other deduction - click on the wizard icon to enter a description of the loss (for example, loss from second trade).

HMRC Forms mode

1. Go to CT600 Core > Computations > Tax adjusted profit/loss – disallowable expenditure.
2. Enter one of the trades' profit or loss in the box labelled Profit/(loss) on ordinary activities before taxation. Then:
   • To declare a separate trade profit, enter the amount in the box labelled Other expenditure not analysed above – click on the wizard icon to enter a description of the profit (for example, profits from second trade).
   • To declare a separate trade loss, Go to CT600 Core > Computations > Tax adjusted profit/loss - other adjustments > Miscellaneous other deduction - click on the wizard icon to enter a description of the loss (for example, loss from second trade).
