GST applicabilty on Rent of a Commercial Property

Dear Sir,

Our Landlord is a charitable trust, was registered under GST before but now their GST status is showing suspended.

we are a registered LLP firm.

Our landlord gave us a tax invoice for Rent of a property without GST.

The property is a commercial property & it is using for commercial purpose.

are we required to pay gst on RCM or any other rules applicable to us?

Please suggest.

and if possible please refer the CBIC circular no.

Thanks & Regards..
