Making Tax Digital - HMRC Error Code 400

[ELMFFA]

Hi. I am getting the following error code when I try and submit a return to HMRC:
Hmrc Error Code: 400
Status: PERIOD_KEY_INVALID
Message: Invalid period key

I think everything is correctly set up. I go to Reports - VAT Returns. Create New VAT Return - it connects to HMRC and I get a list of open VAT obligations as currently reported by HMRC. I click “Prepare” on the one I need to complete. A VAT return is created with the Period Key 1019 which is correct.

“File VAT Return electronically to HMRC” is ticked. I click Submit Return and the error message is returned. Any ideas?

Thanks

Emma

Hi @ELMFFA,

Unfortunately this error lies with HMRC so you would need to get in touch with them

It’s a hmrc error. They need to fix the period to which the returns relate on there end.

Great thanks. HMRC are going to give me a call tomorrow about it.

Didn’t manage to speak with HMRC but they have sorted it out by changing the Period shown. All good now.
