How i verify that vendor has pay tax liability so that I could take tax credit ,The problem is vendor has opted Quarterly return option because he has less then 1.5cr turnover. but GSTR-3B has to file on monthly basis and GSTR 1and 2 on quarterly basis , so how i verify that .

please give suggestions
as soon as possible.
