Reverse Charge in GST, Explained With the Cases You'll Actually Hit

Normally the seller collects GST and pays it to the government. Under the reverse charge mechanism, that flips: the recipient pays the tax directly. It sounds like an edge case. It is not, and most businesses trigger it without noticing.

The Cases You Are Most Likely to Meet

Goods transport. Pay a goods transport agency to move freight and, in most cases, the liability sits with you as the recipient rather than the transporter.

Legal services. Fees paid to an advocate or a law firm by a business entity fall under reverse charge. Your lawyer's invoice will carry no GST, and the obligation is yours.

Director's services. Where a director supplies services to the company in a personal capacity rather than as an employee, the company accounts for the tax.

Imported services. This one catches almost everybody. A foreign SaaS subscription, an overseas contractor, a cloud bill from a supplier with no Indian entity, importing a service means paying IGST under reverse charge. There is no Indian supplier to collect it, so it falls to you.

Sponsorship and certain security services also sit on the list.

The Rule That Costs People Money

Reverse charge liability must be paid in cash. You cannot set it off against your input tax credit balance.

This is where businesses get caught. You might be sitting on a comfortable credit balance and still have to pay reverse charge tax out of your bank account. The good news is that once paid, you can generally claim it back as input tax credit, but the cash goes out first, and the timing matters for anyone managing tight working capital.

Registration Does Not Save You

If you are liable to pay tax under reverse charge, you must register for GST regardless of turnover. The threshold does not apply. A small consultancy well under ₹20 lakh that subscribes to a foreign design tool has, technically, triggered a registration requirement.

What This Means in Practice

Three habits keep it manageable:

1. Flag your foreign invoices. Any payment to an overseas supplier for a service deserves a second look.
2. Account for it in the same period. Reverse charge is declared in your GSTR-3B for the period, and self-invoicing requirements apply where the supplier is unregistered.
3. Budget the cash. Because it cannot be offset, it belongs in your outflow planning rather than your credit ledger.

The Common Mistake

Businesses treat a foreign supplier's zero-GST invoice as though no GST is involved. The invoice is silent because the foreign supplier has no obligation to charge it, not because none is due. The obligation simply moved to you.

If you are paying overseas suppliers regularly and none of this has been accounted for, it is worth a review before it compounds. Talk to us about GST compliance.
