How do i re-authorise MTD for VAT....it says I need to renter login details but where do I do that?

Let me begin that process with you, @adam126. I understand you need to re-authorise MTD in QuickBooks Online. I'll share how to do it.

Before that, did you encounter error while managing your business taxes? If you, we would appreciate if you can give more details so we can provide you the exact solution.

Re-authorizing the connection should done every 18 months, and QuickBooks will send a notification when it's time to re-authorize your Making Tax Digital for you VAT. With that, you need to enter your login details to set up the connection between QuickBooks and HMRC.

I'm also adding this steps to activate your MTD for VAT.

1. In QuickBooks, go to Taxes.

2. Choose Set up MTD.

3. Pick Authorise now.

4. Select Continue.

5. In the window that opens, sign in with your MTD Government Gateway user ID and password. This will be in the confirmation email you receive from HMRC.

6. Click the Continue.

7. Press the Give permission.

8. Once you're connected, select Continue and then Go to Taxes.

Thank you for reaching out to us and allowing us the opportunity to assist you in resolving your concern, @adam126. We are rooting for your success.

I have read the response to this. I also seem to need to re-authorise Quickbooks to file my VAT. I am not seeing a page when I press the taxes button to set up MTD. Please advise. I have tried everything I can think off. I have never had any problems before. 

Hello Eviebee06, thanks for posting on this thread, you should get the option to do so if you go to your taxes page and click on Take Action.
