Hi all,
I wanted to post this here so others don't waste the hours I spent yesterday on this issue!
I was moved over to Core Payroll for this month and ran my first payroll, but the FPS submission to HMRC kept failing saying my credentials were incorrect. I had never had this issue with the old payroll solution and my HMRC password had not changed.
After nearly 2 hours talking to support and re-running the payroll several times, I then had a hunch which turned out to be true. Core Payroll cannot cope with HMRC credentials which contain punctuation. So if you have a complex password that isn't just letters and numbers, you'll have to simplify it in order for Core Payroll to be able to talk to HMRC. Support later confirmed this is the case.
This isn't mentioned anywhere in the support documentation and the support team clearly weren't aware enough of the issue to suggest it straight away (although the people I spoke to were very friendly and were trying their best).
It's a little disappointing that professional software like QuickBooks can't cope with complex passwords, which are good practice.
Anyway, I hope that saves others time if they hit the same issue!
Best wishes,
James
