Thank you i've checked the VAT number is correct. 

How do i check the gateway information?

Also following the steps in the in disconnect and reconnect.... I have disabled the MTD in the taxes tab but when i go to advanced settings it still says MTD on, Any ideas why this?

Hi Sarah, thanks for getting back to us here.

We don't store the Government Gateway information in QuickBooks. If you think the sign in credentials need correcting, you should disconnect and reconnect MTD. 

To disconnect MTD, go to the Gear icon and select Account & settings, then Advanced and Making tax digital. From here, click Learn how to disconnect and follow the on-screen flow to confirm the disconnect. We'll be here if you need any further support!

Hi I keep getting this error message: CLIENT_OR_AGENT_NOT_AUTHORISED

It has been 18 months since I signed up for MTD. I have disconnected and reconnected multiple times, both in the account settings and the VAT settings.

I have also checked the VAT number which  is correct but it is still saying something isn’t right. 

Hi JimDBS Thanks for reaching out to us here on the Community. The Client and/or agent not authorised message indicates that your MTD account within your HMRC portal needs reauthorising, we recommend that you reach out to HMRC for further assistance.

Hi

I have been submitting my VAT return via Quickbooks since early 2020 with no issues at all. Have been trying to submit my July one for the last week, but keep getting a message 'We can't connect to HMRC right now'. I have pressed the green 'Take Action' button, and followed the various links, but nothing has changed. My actual VAT return for this period on Quickbooks is correct, so the underlying data is fine but I just can't send it on. 

Help would be most appreciated! Cheers.

Hi Archie, thanks for dropping by

In most cases where users have been submitting successfully previously and no details have changed on the Gov Gateway account (such as login info), the cause of the message is due to expiration of the authorisation period. 

 As part of HMRC's security requirements, authorisation needs to be provided every 18 months. We'll alert you in product that you need to take action, but if you don't see this, you can still re-authorise by disconnecting MTD in QuickBooks (and then reconnecting). 

If you continue to see any error message after this, please get back in touch below and we'll pick it back up with you. 

Thanks Georgia.

I had tried that before, but it didn't seem to disconnect me even though I was pressing all the right buttons, so I thought it was something else more complicated. I have just been guided by Lee from your on-line help section, and have managed to finally disconnect and reconnect and have submitted my return. Hooray!

Thanks for your guidance.

We are getting an error connecting to HMRC MTD for the last 2 weeks with this error code CLIENT_OR_AGENT_NOT_AUTHORISED

We have tried all steps in help (switching of MTD and back on etc.) and can find no way of re-authorising the connection.  We have used MTD successfully for a long time and all the VAT details are correct. Logging on to HMRC also has no help on this issue.  Please can you help?!

Hi, we are having the same problem you described. Can you please describe what was done differently to switch off MTD and reconnect please? When we switch off MTD and reconnect it comes up with the same error message each time (CLIENT_OR_AGENT_NOT_AUTHORISED). Thanks, Phil

Regarding the HMRC MTD connection issue (CLIENT_OR_AGENT_NOT_AUTHORISED) raised in my two previous posts, I have spoken to a QuickBooks support agent who took me through how to actually disconnect from MTD and reauthorise. The key thing is that going to “Take action” and switching off MTD does not work! You need to go to Settings - Account and settings - Advanced - Making Tax Digital and switch of HMRC connection from there. Then once checked on the tax page that it is off need to go back into the advanced settings and switch it back on at which point it will redirect you to HMRC login to reauthorise.

I suggested to the agent that either they make the “Take action” button route work, or at least publish help to explain how to do it. I assume many others will be experiencing the issue.

I have the same problem.  I've been using MTD for quite a few years now, submitting quarterly returns.  The 3 options on the next page all result in the same error message. I have already signed up for MTD so it's not the first. The second link doesn't help and the 3rd just brings you back to this page once you've inputted your VAT number!

I have also tried disconnecting QB from MTD and HMRC and then reconnecting.  Still the same error code.

I seem to be stuck in a loop.  Please advise how to fix as I only have till the end of the week to file my VAT return!

Thank you

Thank you for sharing a screenshot, Helen. 
 

The error CLIENT_OR_AGENT_NOT_AUTHORISED indicates that QuickBooks is no longer authorized to connect to HMRC or that your credentials are incorrect. This occurs due to the following reasons:
 

• Connection to HMRC has expired (18 months)
• Incorrect credentials
• HMRC hasn't authorized your agent services account
• VAT registration number doesn't match HMRC records.
   

Since you've reconnected, confirm you're using your MTD credentials during the process. Make sure not to use general Government Gateway credentials. Refer to this article for more info: Fixing MTD (Making Tax Digital) issues in QuickBooks Online.
 

If the same error occurs, I recommend contacting our live support team. They have the resources to further verify this situation and ensure you can file your VAT returns on time.
