Hello dimo_60, thanks for posting on the Community.
Checking our system, we don't currently have any reported issues with recording VAT payments on the taxes screen.
To check for any browser issues that may be causing this, please try entering the payment by logging into QuickBooks via a different web browser or incognito window.
If you're still unable to post the payment after this, please copy and paste the error that you see (or add a screenshot) below.
