Dear SirMadam,
We taked legal service from advocate (Karnataka states) and he send bill to us (Mumbai) Rs.100000/- without any GST Charged. We have paid Rs.90000/- after deduction of TDS.
But advocate firm are Registerd under GST and he mention the GSTIN on his Bill.
And also mention in his bill - GST as appliable is payable by the service receiver on reverse charge Mechanism.
The firm want to charged GST on his bill but why not charged .
The firm is registered under the GST Act.
The GST Tax is appliable - IGST- @18% - this is correct or wrong

Please advise in above matters as earliest.

Thank & Regards
