Liability on TDR/FSI under GST

[Shreyansh Mehta]

What should be the liability of TDR purchase in Cash under GST and when should be it is payable??

As per my knowledge we have to calculate TDR liability at the time of receiving Completion certificate and it should be payable on remaining unsold flats. But i am confused because i had purchase TDR by paying consideration in Cash and i have to pay liaibility on RCM basis at the time of completion certificate. If i agree to share area or revenue then my liability will be determine at the time of completion certificate in area sharing and in revenue sharing at the time of revenue earned.But if i purchase TDR in cash then what should be my liability and when should i have to pay???

Please guide me regarding my issue

Thankyou

AI Summary

GST liability on TDR: reverse charge applies for unsold residential units at completion or first occupation; commercial TDR taxed on payment.
For residential projects, a promoter who acquires TDR must pay GST under the reverse charge mechanism on the proportionate value attributable to residential apartments that remain unbooked on the date of issuance of the completion certificate or first occupation, whichever is earlier, calculated by the ratio of unbooked residential carpet area to total residential carpet area and subject to prescribed caps; for commercial TDR the liability generally arises at the time of payment of consideration.
