To help your Making Tax Digital submission run smoothly, we've compiled a short list of articles that address the issues Sage customers have reported.
I get a blank page when it tries to do the submission on some companies and it goes straight through to HMRC on others. This is very annoying as I have tried to file one company 6 times, I have logged off, exited and reopened as administrator, shut my pc down and still can't file it. Sage is not a cheap product and I don't think its unreasonable to expect it to work. Why is this happening and how can I get it to work?
Normally this happens if you have firewall and/or antivirus running on the background on the PC through which you are trying to submit the VAT. Simply temporarily disable the antivirus and submit the VAT through Sage. It will go through normal and once submitted you can enable the antivirus again.
Hope it will help.
