Key terms
- GSTR-2B (s. 16(2)(aa)): A monthly statement on the portal listing the bills your suppliers have reported. It is the list your credit is checked against.

Common questions
What are the conditions for input tax credit?
You must hold the tax invoice, the bill must appear in your GSTR-2B, you must have received the goods or services, the supplier must have paid the tax, and you must file your return (section 16(2)).
Can I claim GST on a car or on food?
Generally no. Section 17(5) blocks credit on cars for people (with a few business exceptions), food and drink, club fees and personal use.
What if I don’t pay my supplier within 180 days?
You reverse the credit on that bill with interest, and claim it again once you pay.
