have been connected with vat for many years. For some reason when I agree for quickbooks to connect having entered the code it doesn`t work

You want to make sure that the code has not expired and you entered it correctly, @roy22.

The code acts as a form of authentication, verifying that you're authorized to access the system or link your account successfully. Also, make sure that you have a stable internet connection to avoid interruptions in the process of authenticating the code.

Alternatively, you can perform a basic troubleshooting in your browser, which disregards website cache, and doesn’t save any browsing history or data. Here's how:

• Google Chrome and Microsoft Edge: Press Ctrl + Shift + N
• Mozilla Firefox: Press Ctrl + Shift + P
• Safari: Press Command + Shift + N

Once done, please return to your regular browser and clear its cache. This will refresh the website preferences that may be causing your issue. Alternatively, consider using other devices and supported browsers for optimal performance.

Once the recommendations above resolve your issue, check out this article: Manage VAT payments in QuickBooks Online. It contains instructions that will help you record, adjust, and delete VAT payments in the tax centre.
