CT600 online form filling

My turnover is greater than my expenses for the year - we made a profit. But when I enter numbers for Director, Staff and general expenses it calculates a loss for the year. Do I need to put negative numbers for expenses?

Hi Duncan Galloway,
If you are using HMRC’s online filing software, then you will not be able to enter any negative expenditures.
Please use the help button on HMRC’s software and provide screen images of the accounts and computations pages together with any error messages generated so we can look at the  matter further.
You will be able to attach screen shots using the help facility.
If you are using commercial software, then please approach the software provider for help. 
Thank you.
