What is Reverse Charge Mechanism?
RCM catches many Delhi businesses by surprise. I have seen ₹2+ lakh demand notices from unaware companies. Under normal GST, the supplier charges and pays tax. Under Reverse Charge Mechanism (RCM), the recipient (buyer) pays the tax directly to the government instead of paying it to the supplier.
Official Reference: Section 9(3) of the CGST Act 2017 specifies categories where RCM is mandatory. Section 9(4) was originally for purchases from unregistered dealers but has been suspended. Currently, RCM applies only to notified categories under Section 9(3).
Services Under RCM
The following services attract mandatory reverse charge:
- Legal services -- by an advocate to a business entity
- GTA (Goods Transport Agency) -- freight services (option available)
- Services by director -- to a company (sitting fees, commission)
- Insurance agent services -- to insurance company
- Recovery agent services -- to banks/financial institutions
- Security services -- provided to registered business
- Manpower supply -- to registered business
- Services by unregistered to registered -- for certain categories
📍 Real Example -- Company Paying Director Fees -- Connaught Place
A private limited company in Connaught Place pays ₹2,00,000 as director sitting fees. Under Section 9(3), this attracts RCM. The company (not the director) must pay: 18% GST = ₹36,000 (₹18,000 CGST + ₹18,000 SGST). The company then claims ₹36,000 as ITC. Net cost: zero, but failure to pay means penalty equal to tax amount = ₹36,000 under Section 271C.
⚠️ Common Mistake: The most common RCM mistake: companies pay director fees but do not pay RCM. The director is not registered under GST (individual, below threshold), so the company must self-assess and pay. Many companies miss this entirely -- and the penalty is equal to the tax amount!
How to Account for RCM in Returns
- Self-invoice: Issue an invoice for RCM services (you are both supplier and recipient)
- GSTR-3B Table 3.1(d): Report RCM liability
- GSTR-3B Table 4: Claim ITC on the same RCM (if eligible)
- Net effect: usually zero additional outflow (liability = ITC)
Official Reference: Rule 46 of CGST Rules requires a self-invoice for RCM purchases from unregistered persons. The invoice must contain all mandatory fields including your own GSTIN as both supplier and recipient. This self-invoice is the basis for ITC claim.
ITC on RCM Payments
Good news: you can claim ITC on the RCM you pay. The conditions are the same as regular ITC under Section 16:
- You must be registered under GST
- The service must be used for business purposes
- You must have a self-invoice or supplier invoice
- The service must not be blocked under Section 17(5)
📍 Real Example -- Legal Services RCM -- Delhi Startup
A startup in Nehru Place pays ₹1,50,000 to an advocate for legal services. RCM @ 18% = ₹27,000. The startup: (1) Creates a self-invoice, (2) Pays ₹27,000 as RCM in GSTR-3B, (3) Claims ₹27,000 as ITC in the same return. Net outflow: zero. But if they miss the RCM payment, the penalty under Section 271C is ₹27,000 (equal to the tax amount) plus interest.
💡 Pro Tip from Parul: Create a separate register for all RCM liabilities. Track every payment to directors, advocates, and transporters. At the time of GSTR-3B filing, ensure all RCM is reported in Table 3.1(d) and corresponding ITC is claimed in Table 4. Miss even one, and you face penalty.
Common RCM Mistakes
- Not identifying RCM applicability -- especially on director fees and legal services
- Not issuing self-invoice -- required for RCM from unregistered suppliers
- Not paying RCM but claiming ITC -- ITC without payment is illegal
- Treating RCM as normal supply -- reporting it in wrong GSTR-3B table
💡 Pro Tip from Parul: I review RCM compliance for all my clients during monthly return filing. This single check has saved businesses from lakhs in penalties. My monthly compliance package starts at ₹1,499/month. Call/WhatsApp: +91 95401 04776

Frequently Asked Questions
Is RCM applicable on GTA (transport) services?
Yes, but there is an option. Under RCM, the recipient pays 5% GST (without ITC) or 12% GST (with ITC). Alternatively, the GTA can charge GST forward and the recipient can claim ITC. Most Delhi businesses opt for RCM at 5% without ITC for simplicity.
Can I claim ITC on RCM paid?
Yes, ITC on RCM is fully claimable under Section 16, provided the service is used for business and not blocked under Section 17(5). In most cases, the RCM liability and ITC cancel out in the same GSTR-3B, resulting in zero net outflow.
What is the penalty for not paying RCM?
Under Section 271C, penalty equals the tax amount (100% of RCM not paid). Plus interest under Section 50 at 18% per annum from the due date. For ₹1 lakh RCM not paid for 6 months, total liability: ₹1,00,000 tax + ₹1,00,000 penalty + ₹9,000 interest = ₹2,09,000.
