My uncle have rented their property to Muthoot Finance ltd. Muthoot always deduct TDS on rent @ 10% which is shown in 26AS but from 1 July 2017 Muthoot starts deducting GST @ 12% but my uncle annual service is upto only 6,00,000 so my question is
1. How to claim back the deducted GST ?
2. My uncle need to register under GST?
3. Why they are deducting the GST onbehalf of my uncle without any notice?
