Submit Accounts Failed

Hi,
I have a dormant company I am trying to file accounts, I have my CH 6 digit code which works when I login to EWF but not working when I use the code here. It is a different email address than I use on tinytax, is that the problem?
thanks

Hi Kevin,

I've looked into this and can see the issue. You have two companies registered:

DOHERTY ENTERPRISES GROUP LTD (13602455) — submitted successfully ✓

DYAGONAL LTD (13642968) — rejected with “Invalid CompanyAuthenticationCode”

Each company has its own unique 6-character authentication code. It looks like you may have used the same code for both companies — the code that works for DOHERTY ENTERPRISES won’t work for DYAGONAL.

To get the correct auth code for DYAGONAL LTD, you can request a new one from Companies House at:
https://ewf.companieshouse.gov.uk/reminders

The email address you use on TinyTax vs Companies House doesn’t affect this — the auth code is specific to each company.

Let me know if you need any further help!

Hi,
Yes it was getting confused between company no. and auth code.
Sorted now.
thanks
