Qs on Tax

Hi Guys

I have a situation where we need to input a direct entry to the Tax Account...

Cr - Vendor and Dr - Tax account as in the 100% of invoice goes into the tax account.

This is not possible since our tax account has the check - post automatically only. And they dont want to uncheck this...

Is there a workaround to get this requirement to work

Thank you for the support
