Re MTD when I try to submit a VAT return it says 'We can’t connect to HMRC . Please advise what I need to do to resolve this. Thanks

Hi there. claire.

Issues like this happens when the filer is not authorized. You might want to check the confirmation email from HMRC and verify if the right VRN was used. 

If it was and still unable to file, I would recommend contacting the phone support team. They have extra tools like screen sharing to help you investigate the issue further. 

Here’s how you can reach them:

1. Click Help at the top. 
2. Select Contact us. 
3. Provide a brief explanation about your concern. 
4. Click let's talk. 
5. Select  Get a callback.

Please consider posting here again if you have other questions.
