I can help you reconnect your QuickBooks to HMRC, @info1552.
Let's start by accessing your account using a private or incognito browser. There are times that the browser is full of frequently-accessed page resources, thus causing websites, like QuickBooks, to act weirdly. You can use any of these keyboard shortcuts:
- Ctrl+ Shift + N for Google Chrome .
- Ctrl + Shift + P for Mozilla Firefox and Microsoft Edge .
- Command + Shift + N for Safari .
Once logged in, you can try submitting your VAT return via MTD again. If it was successfully sent, you'll need to go back to your regular browser and then clear the cache to delete the accumulated site data and junk files. Alternatively, you can switch to other supported browsers to further isolate the issue.
If the issue persists, I'd recommend contacting our Customer Care Team. One of our specialists can securely access your account and further look into the root cause of the issue you're getting.
I appreciate your patience while we look into this. Let me know how it goes after contacting them. I’m always here to make sure this is taken care of.
