GST EXEMPTION ON RENT

HELLO ALL,

I HAVE A PROPERTY, WHICH I HAVE GIVEN ON RENT TO SBI. SBI IS RUNNING ITS TRAINING CENTRE IN IT, PRIOR TO GST S.TAX WAS EXEMPTED ON RENTAL OF SAID BUILDING AS SBI WAS NOT RUNNING ITS TRAINING CENTRE FOR EARNING PURPOSE AND AS PER FINANCE ACT 2010 IMMOVABLE PROPERTIES ON RENT WHICH ARE NOT IN USE FOR COMMERCIAL PURPOSE ARE EXEMPTED FROM S.TAX. NOW, WHEN SERVICE TAX IS SUBSUMED WITHIN GST WHETHER I NEED TO GET REGISTER AT GSTN AND RAISE A GST LEVIED INVOICE ON SBI OR GST IS ALSO STAND hai EXEMPTED IN SUCH A CASE .

kindly guide.
