How to enter multiple trades on the CT600?

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

1. Go to CT600 Core > Trade and professional income > Tax adjusted profit/loss – disallowable expenditure.
2. Enter the net effect of the trades added together in the box labelled Profit/(loss) on ordinary activities before taxation.
3. 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).
4. Go to Computation Management , click on Edit Notes > select Profit and Loss on the left menu > Trading Losses Summary.
5. Enter the amount of losses.

HMRC Forms mode

1. Go to CT600 Core > Computations > Tax adjusted profit/loss – disallowable expenditure.
2. Enter the net effect of the trades added together in the box labelled Profit/(loss) on ordinary activities before taxation.
3. 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).
4. Go to Computation Management , click on Edit Notes > select Profit and Loss on the left menu > Trading Losses Summary.
5. Enter the amount of losses.

How to attach the PDF computation documents to the return

2. Click on Attach.
3. Under Other, click on Add Other PDF.
4. Browse to find the PDFs.
5. Select the PDFs and click on Open to attach them – make sure the file extension (.pdf) is lowercase.
