Hello Genreve Thank you for your suggestions to fix my problem with the BAS worksheet not having any data in it. I have now resolved my problems by having an accountant create a new *.bas data file and link it to the BAS worksheet and BAS return. I am working off-line, so when the BAS has been calculated, I use the figures to lodge the return on the ATO Portal. Thanks once again for your help. FRaymond Recovery of data to fill in BAS. My GST worksheet screen is blank. I selected the wrong financial year (March 23 instead of March 24) and got a message to say I was using an old version and did I want to update? I said yes, not realising my mistake at that stage, and now when I select the March 2024, the screen is blank. I have found the original data file (I think!) but do not know how to import it so that I can calculate the March 2024 BAS. Can any one help?
