Error Message when attaching PDF Accounts and Tax Comps to Online CT600
... I'm receiving an error message at the end page when I push the "submit" button:
"X ERROR:You have attached PDF accounts but not selected a reason to show why no iXBRL accounts are attached."
A drop down box offers me the option to select "PDF accounts attached with explanation". But I have no explanation... other than it's only 30th March, and I have five CT600s to file, all with pdf accounts and tax return as attachments. (I've looked up HMRC's staff notes, which instruct staff to check my pdf attachments for my "explanation" as to why I've used pdf and not iXBRL).
Oughtn't the Revenue accept pdf accounts and tax attachments to their online CT600s up until 31st March? Has the online filing service pulled its shutters down early? Would I be better off dropping off paper copies at the nearest HMRC office tomorrow (31st March)?
