GST Registration Under Reverse Charge Mechanism: What Businesses Should Know

Under normal GST rules, the supplier of goods or services is responsible for collecting and depositing tax with the government. Reverse charge mechanism flips this responsibility onto the recipient of the supply for certain specified categories of goods and services, and this has a direct bearing on GST registration because it removes the usual turnover-based exemption for many businesses that would otherwise not need to register.

Key Insights

Under Section 24 of the CGST Act, any person required to pay tax under reverse charge must register for GST regardless of their aggregate turnover, meaning even a small business with revenue well below the standard registration threshold becomes liable to register the moment it receives a notified supply covered under reverse charge, such as legal services from an advocate, services from a goods transport agency without a consignment note, or specified supplies from an unregistered supplier in certain categories. This is a frequently overlooked trigger, since many small business owners assume threshold exemptions apply universally.

Key Insights

Once registered on account of reverse charge liability, the business must self-invoice for the covered supply, pay the applicable tax directly to the government through its electronic cash ledger, and can generally claim input tax credit for that tax paid, provided the goods or services are used for business purposes and other input tax credit conditions are satisfied. This effectively means the recipient temporarily bears both the tax payment and, in many cases, the credit benefit, which is different from how businesses typically think about their GST cash flow when dealing only with forward-charge suppliers.

Key Insights

Businesses that regularly engage professionals like advocates, use goods transport agencies for logistics, or import certain specified services from outside India should specifically evaluate whether their activities trigger mandatory reverse charge registration, rather than waiting until their overall turnover crosses the general threshold. Getting this wrong is a common compliance gap uncovered during departmental audits, since the reverse charge liability accrues from the date the covered supply was received, not from the date the business eventually registers, which can result in interest and penalty exposure for the period the business operated without the required registration.
