Our Development team has checked the error logs and this message relates to the ‘period key’ given by the HMRC systems is incorrect, as this warning comes from HMRC then you will need to contact there support line as most likely they have the wrong period key (as prior enquiries on this have been fixed by HMRC). You can try some KB steps below but if they all fail then you need to contact HMRC.

Period Keys come from HMRC (Only they have access to it)

IRIS doesn’t store this key information and nor can IRIS edit or change this period key.

Read further below on some ways for a possible fix – if none work then you need to contact HMRC.

Go through these three KBs to see if they can resolve the issue:

We also have this KB VAT check list if you want to go through this before you call HMRC in case this can fix it (eg Rest your agent credentials and log back in). https://www.iris.co.uk/support/knowledgebase/kb/vat-filer-internal-server-error-or-date-periods-vanish-or-agent-client-not-authorised/

Please ensure the clients registration for MTD has been completed successfully via your HMRC ASA login (this is a HMRC rule) https://www.iris.co.uk/support/knowledgebase/kb/vat-authorise-the-software-to-interact-with-hmrc/

If you get a Yellow triangle as well, read this KB https://www.iris.co.uk/support/knowledgebase/kb/vat-filer-yellow-triangle-for-a-period-rejected-failed-to-submit/

However, if the these fixes provided do not work, then you will need to contact HMRC support: when you get through to them, ask to be connected with a senior member of staff as they will have more knowledge of this subject.
