I want to set up MTD for VAT in QuickBooks Online and connect to HMRC but I can't seem to access MTD. I can't see the MTD item on the Taxes Page and Advanced Page.

I'm here to help you submit your taxes, hannah-blackcomp. 

After we've signed up MTD on the HRMC website, we'll also need to enable it within QuickBooks. 

Here's how: 

1. Go to the Gear icon and select Account and Settings.
2. Click the Advanced menu.
3. Select Making Tax Digital and then click Learn how to connect.
4. Click Let's go.
5. Another window will open for us to authorise QuickBooks to interact with HMRC. Click Continue.
6. Enter the HMRC log in credentials.
7. Once logged in, click on Grant authority.
8. From the You're connected to HMRC message, select Continue.
9. Click Take a look once process has been completed.

MTD is now enabled on the Taxes page which we can now submit a VAT return via MTD. 

If you're still unable to submit after turning on MTD, it can be that a browser-related issue is causing the errors. Stored cache files sometime causes QuickBooks unexpected behavior. We can remove those files to fix the issue. 

1. Let's access QBO and submit VAT through private browser since it doesn't store any history or cache files.
2. If you were able to submit it without any errors, we can remove the cache files stored in your regularly used browser.
3. Other ways to get away with unusual behaviors is switching to other browsers such as Google Chrome, Internet Explorer, Safari, or Mozilla Firefox.

Keep me posted on how this works. I'll keep an eye on it!
