If the landlord is not a registered dealer in GST , then the gst will come under reverse charge & should be paid to the dept. by tenant

If the landlord is not a registered dealer in GST , then the gst will come under reverse charge & should be paid to the dept. by tenant

Landlord is not registered.

He does not issue us an invoice. How do we show it as Reverse Charge without an invoice ?

If the landlord is not registered & not raising an invoice , then the self invoicing is to be done.
ie, the invoice should be created by the registered person . U can take the amount as input.
Instead of service provider (landlord ), Service receiver ( tenant ) is paying the gst .This is the only difference in Reverse charge .

u can refer the following link for reference.

Thanks for your response Jobin.

Is there a specific format for Self Invoicing to be used ?

Any sample self invoice shall be great help.

Hi , there is no specific format for self invoicing. But the fact is that invoice should be GST compliant. If u r maintaining tally u can print the voucher from tally itself.
