Unfortunately, you cannot enter multiple trades on the CT600.
Instead you need to enter the combined figures into the computation to show the overall position and then attach a PDF computation for each trade to show the individual computations. This can be done in either SimpleStep or HMRC Forms mode:
SimpleStep mode
- Go to CT600 Core > Trade and professional income > Tax adjusted profit/loss – disallowable expenditure.
- Enter the net effect of the trades added together in the box labelled Profit/(loss) on ordinary activities before taxation.
- To declare a loss separately, enter the amount in the box labelled Other expenditure not analysed above – click on the wizard icon to enter a description of the loss (for example, loss from second trade).
- Go to Computation Management , click on Edit Notes > select Profit and Loss on the left menu > Trading Losses Summary.
- Enter the amount of losses.
HMRC Forms mode
- Go to CT600 Core > Computations > Tax adjusted profit/loss – disallowable expenditure.
- Enter the net effect of the trades added together in the box labelled Profit/(loss) on ordinary activities before taxation.
