Connection to HMRC

I had a message to reactivate link to HMRC.

When I clicked on the link it said “HMRC Connection Error NOT_FOUND. The remote endpoint has indicated that no data can be found” Under status it says “failed”.

However a link to reactivate was there so I clicked on it and went through the motions to reactivate. Nothing to indicate it hadn’t worked but when it reverted to Quick file page, the HMRC message and failed status was still there.

Is there a way of knowing whether the reactivation has worked?

Hello @Diana2024

Please refer to the troubleshooting guide below for HMRC errors

https://support.quickfile.co.uk/t/making-tax-digital-troubleshooting/37144

I’ve checked the link to to HMRC. It listed Quick file as having been authorised. I removed authorisation and then reinstated it. It now says authorised from 7th Feb 2026 BUT my quickfile page is still showing the error message and “failed” under status.

Can you advise please?

Hello @Diana2024

We have no control over the authorisation process.

I would reccomend clearing the authorisation on your HMRC account and removing it from the Reports > HMRC screen then setting the link up again.

The “Client not Authorised” message is returned by HMRC when we try and log in behind the scenes using the detail you provide.

If you are still having issues after doing this I would reccomend contacting HMRC directly.

I know how to clear the authorisation at HMRC end but how do I remove it “from the Reports > HMRC screen then setting the link up again”. Will I lose any data from previous submissions?

Hello @Diana2024

how do I remove it “from the Reports > HMRC screen

Click the Disconnect option to remove the link, Then use the connect option to start the process again.

Will I lose any data from previous submissions?

No, it just removes the current link.

Thank you for your help.

Hello again. I’ve tried everything I can think of, disconnected everything and reconnected and it still shows up with the error message and failed status. Furthermore, I’ve separately tried to link up a self-assessment acct for MTD (using correct HMRC info) and it’s defaulted to the VAT account and says I can’t use the details to file VAT returns (which I didn’t want to do anyway). What’s going on? Do I just need to completely delete the account altogether or move to some other software?

Thanks. But how do I get round the problem where when I try to log in to Quickfile for self assessment with the correct information, it defaults to the VAT account? Quickfile just sends me to VAT account and has message

Client not Authorised. The account you have linked to QuickFile is not authorised to access or file VAT information for the VAT registration ……

which as I’ve explained I am not trying to do! I’m trying to access how to do quarterly reports for MTD.

Just to let you know, I tried the MTD thing one more time and it now seems to have miraculously sorted itself out. Sorry to bother you again. So just need to sort out the VAT issue now.

I suspect the issue is that if you connect one account, and in doing so you sign in to HMRC with the appropriate ID, then you go back to QuickFile and try to connect the other account, then when QuickFile redirects you to HMRC the second time your browser sees you as already signed in and doesn’t give you the opportunity to use the other gateway ID.

Once you’ve completed the first connection you would need to navigate back to the HMRC site and actively “log out” over there, before you start on the second connection from the QuickFile end. That way HMRC should give you a fresh login prompt and you can sign in using the correct gateway ID.
