Rcm on consultancy charges paid

Dear Seniors,

I would like to request to give solution to my query noted below :

We are machine manufacturer and registered under GST and having yearly turnover of more than 1.5 crore. We do hire consultant for designing and planning  for which we have to pay consultancy fee but recently one of my consultant is not registered under GST  so is it mandatory for me to pay 18% RCM on the amount paid or I can get relief as per circular of goverment of stopping RCM till 31st March 2018. Please do advice whether it will attract any TDS or not which I think is not applicable.

Thanking in anticipation,

Regards,

YOGESH
