When a business receives a taxable service from the Central Government, a State Government, a Union territory, or a local authority, the business itself must calculate and pay the GST on that transaction rather than the government department collecting it. This is how the reverse charge mechanism on government services works, and it applies to almost every category of government service supplied to a business entity, with only a short list of exclusions and a narrow exemption for consideration up to Rs. 5,000.
When Reverse Charge Applies
Section 9(3) of the CGST Act lets the government specify categories of supply on which the recipient pays tax instead of the supplier.1Central Board of Indirect Taxes and Customs. Central Goods and Services Tax Act 2017 – Section 9 Entry 5 of Notification No. 13/2017-Central Tax (Rate) applies that power broadly: any service supplied by the Central Government, State Government, Union territory, or local authority to a business entity is covered, unless it falls within one of the specific carve-outs.2Central Board of Indirect Taxes and Customs. Notification No. 13/2017-Central Tax (Rate)
“Business entity” is defined broadly. It includes any person carrying on trade, commerce, manufacturing, a profession, or a vocation. Size and industry do not matter. A sole proprietor paying for a licence and a large company paying a regulatory fee face the same reverse charge obligation.
Common examples include security services provided by government police agencies to private businesses or public sector undertakings, government assignment of rights to use natural resources (royalty and similar consideration is taxed in the licensee’s hands), and fees for government testing, certification, licensing, and regulatory approvals.3GST Council.

Services That Are Excluded
Notification No. 13/2017 lists four categories of government services that stay on forward charge, meaning the department itself collects the tax:2Central Board of Indirect Taxes and Customs. Notification No. 13/2017-Central Tax (Rate)
- Renting of immovable property by a government body.
- Speed post, express parcel post, life insurance, and agency services of the Department of Posts to non-government recipients.
- Services in relation to an aircraft or vessel, whether inside or outside a port or airport.
- Transport of goods or passengers.
Services flowing between government departments are generally exempt from GST altogether, so the reverse charge question does not arise for them.3GST Council. FAQ on Government Services Under GST
Entry 9 of Notification No. 12/2017-Central Tax (Rate) also exempts government services from GST entirely when the total consideration does not exceed Rs. 5,000.4Central Board of Indirect Taxes and Customs. Notification No. 12/2017-Central Tax (Rate) Two limits on that exemption matter. For a continuous supply of services, the Rs. 5,000 threshold is measured across the whole financial year, not per bill; a recurring monthly fee of Rs. 500 will exhaust it in ten months and GST becomes payable on the total once the cumulative consideration crosses the limit. And the exemption does not extend to the four excluded categories above, which remain taxable on forward charge regardless of amount.
Registration Is Mandatory, Whatever Your Turnover
Section 24 of the CGST Act requires anyone liable to pay tax under reverse charge to register for GST, regardless of turnover.5Central Board of Indirect Taxes and Customs. Central Goods and Services Tax Act 2017 – Section 24 The normal thresholds of Rs. 40 lakh for goods (Rs. 20 lakh in special category states) and Rs. 20 lakh for services (Rs. 10 lakh in special category states) do not protect you. If your business receives a taxable government service on which the Rs. 5,000 exemption doesn’t apply, you must register.
When the Liability Arises
Section 13(3) of the CGST Act fixes the time of supply for reverse charge services as the earliest of these dates:6Central Board of Indirect Taxes and Customs. Central Goods and Services Tax Act 2017 – Section 13
- The date the payment is entered in your books or debited from your bank account, whichever is earlier.
- The date immediately following 60 days from the invoice or demand notice issued by the government department.
- The date the recipient issues a self-invoice for the transaction.
If none of these can be determined, the fallback is the date the transaction is recorded in your books.6Central Board of Indirect Taxes and Customs. Central Goods and Services Tax Act 2017 – Section 13 Most government fees are paid upfront or shortly after the demand, so the payment date usually triggers the liability.
Self-Invoice and Payment Voucher
The government department will not issue you a GST-compliant tax invoice, so you have to create two documents yourself.
Section 31(3)(f) of the CGST Act requires you to issue a self-invoice for the service received.7Central Board of Indirect Taxes and Customs. Central Goods and Services Tax Act 2017 – Section 31 It must carry the name and address of the government department, a description of the service, the applicable GST rate, and the correct SAC (Services Accounting Code). The SAC drives the classification and the rate, so getting it right is not optional.
Section 31(3)(g) then requires you to issue a payment voucher at the time you pay the government department.7Central Board of Indirect Taxes and Customs. Central Goods and Services Tax Act 2017 – Section 31 File both documents together. Missing or incomplete self-invoices can lead to denial of your Input Tax Credit later, which effectively doubles the cost of the transaction.
Paying Through the Electronic Cash Ledger
Reverse charge tax has to be paid by debiting your Electronic Cash Ledger on the GST portal. You cannot offset it against existing Input Tax Credit at the time of payment; the full amount must be funded in cash.8Goods and Services Tax Council. Reverse Charge Mechanism If your business normally nets liabilities against ITC balances, plan for the actual liquidity.
Deposits into the cash ledger are made through the GST portal using net banking, NEFT, RTGS, or over-the-counter payment at authorised banks.9Goods and Services Tax. Electronic Cash Ledger The deposit sits in the ledger until you assign it to the reverse charge liability; it does not apply automatically.
Reporting in GSTR-3B
The reverse charge liability is reported in Table 3.1(d) of GSTR-3B, the row designated for inward supplies liable to reverse charge.10Goods and Services Tax. Form GSTR-3B Monthly filers are due by the 20th of the following month.
The figures in GSTR-3B must reconcile to your self-invoices. GSTR-2B will auto-populate some reverse charge data, but verify the entries against your own records; discrepancies are a common trigger for scrutiny notices.
Claiming Input Tax Credit
Once you have paid the reverse charge GST in cash, you can claim it back as Input Tax Credit in the same return period. The service must be used for business purposes, and you must hold a valid self-invoice and payment voucher.8Goods and Services Tax Council. Reverse Charge Mechanism The credit can then offset your output tax liability on other supplies.
Section 17(5) of the CGST Act blocks ITC for certain categories regardless of whether the tax was paid under reverse charge:11Central Board of Indirect Taxes and Customs. Central Goods and Services Tax Act 2017 – Section 17
- Motor vehicles with seating capacity of 13 or fewer (including the driver), unless used for further supply, passenger transport, or driving training.
- Outdoor catering, health services, cosmetic procedures, and life or health insurance.
- Works contract services and goods or services used for constructing immovable property (other than plant and machinery) on your own account.
- Fitness centre memberships and leave travel concessions for employees, unless required by law.
Most government regulatory services (licences, permits, testing fees, security services) sit outside these blocks, so ITC is usually available. Where a government service does touch a blocked category, you pay the reverse charge GST in cash and cannot recover it.
Interest for Late Payment or Wrong Credit
Section 50 of the CGST Act charges interest at 18% per annum on unpaid reverse charge tax, running from the day after the due date until actual payment.12Central Board of Indirect Taxes and Customs. Central Goods and Services Tax Act 2017 – Section 50
A separate higher rate of 24% applies where Input Tax Credit is wrongly claimed and actually used, for instance where credit is taken on a reverse charge payment that was never actually made through the cash ledger, or on a blocked category of service.12Central Board of Indirect Taxes and Customs. Central Goods and Services Tax Act 2017 – Section 50 The two are distinct: 18% is the price of paying late, 24% is the price of taking credit you weren’t entitled to.
Failure to issue a self-invoice can also lead to outright denial of the ITC. The GST system treats the self-invoice as the foundational document for the credit. Without it, the cash you paid stays paid and the credit is lost.
