Reverse Charge Mechanism in GST: What Gujarat Freelancers and Service Businesses Must Know

TL;DR

Under reverse charge mechanism (RCM), the recipient of a service — not the supplier — pays GST directly to the government. For freelancers and service businesses in Gujarat, RCM commonly applies when you receive payments from: an unregistered business client, a government department, or specified services like legal, professional, or GTA services. Even if your invoice shows no GST, you may need to pay it under RCM and claim input tax credit (ITC) where eligible.

Quick Answer

RCM shifts GST payment obligation from the service provider to the service recipient. If you are a freelancer or service business registered under GST, check whether your client is unregistered — if so, you likely need to pay GST under RCM on that payment. File RCM entries in GSTR-3B and consider whether you can claim ITC on the tax paid.

What Is Reverse Charge Mechanism

In normal GST, a registered supplier collects tax from the buyer and remits it to the government. Under reverse charge, the flow reverses: the recipient of the supply pays GST directly instead of the supplier.

This matters because many service providers assume: “No GST on my invoice means no GST to pay.” That is not always true.

Example: You are a graphic designer in Surat. A local retailer (not GST-registered) hires you for a logo. Your invoice is ₹25,000 with no GST. Under RCM, you must still pay 18% GST (₹4,500) on this payment to the government — even though you did not collect it from your client.

Who Pays GST Under Reverse Charge

Registered businesses receiving from unregistered suppliers

The most common RCM trigger for Gujarat freelancers and small service providers: you provide a service to a client who does not have a GST registration.

Supplier status	Recipient status	RCM applies?
Unregistered	Registered	Yes — on goods and services
Registered	Registered	No — normal forward charge
Unregistered	Unregistered	No GST charged

Government and PSU recipients

Supplies to the Central Government, State Government, Embassy, High Commission,联合国 (UN bodies), and specified local authorities attract RCM regardless of the supplier’s registration status.

When RCM Applies for Freelancers in Gujarat

Scenario 1: Unregistered business client

You run a web development business in Ahmedabad. A local medical store (no GSTIN) pays you ₹80,000 for an e-commerce site. Even though your invoice has no GST, you must:

1. Pay ₹14,400 GST (18% on ₹80,000) under RCM
2. Report it in GSTR-3B Table 1.4
3. You can claim this as ITC if you use the input for your business

Scenario 2: Services from unregistered professionals

You hire a freelance photographer in Rajkot for a product shoot. The photographer is not GST-registered. Your business must pay GST on their fee under RCM.

Scenario 3: GTA services

If you use a Goods Transport Agency for moving goods — common for traders in Surat’s textile markets or chemical businesses in Vadodara — you pay GST under RCM at 5% (or 12% depending on the goods type) on the freight charges.

How to Calculate GST Under Reverse Charge

For services where RCM applies, calculate GST on the value of consideration (the amount you pay for the service).

Example: RCM Calculation

You are a consultant in Gandhinagar. A Vadodara-based unregistered manufacturing firm pays you ₹1,50,000 for process optimisation advice.

• Service value: ₹1,50,000
• GST rate (assuming 18% service): ₹27,000
• Total amount payable to government: ₹27,000

Note: You do not collect this GST from your client. You pay it yourself from your business account and claim ITC (if eligible).

Step-by-Step: Filing RCM in GSTR-3B

RCM is not a separate return. It gets reported in your monthly GSTR-3B.

1. Identify RCM transactions: Before filing, list all payments to unregistered suppliers and specified services
2. Calculate GST: Compute the GST amount on each RCM transaction
3. Enter in Table 1.4: In GSTR-3B, go to Table 1.4 — “Value of reverse charge supplies received from unregistered suppliers”
4. Enter tax amounts: Show the CGST, SGST (or IGST) separately
5. Pay tax: Remit the total RCM tax before the GSTR-3B due date (usually 20th/22nd of following month)
6. Claim ITC: If the services relate to your business, claim the tax as input tax credit in Table 4 of the same GSTR-3B

Common Mistakes Gujarat Businesses Make

Mistake 1: Assuming no GST invoice means no RCM liability

This is the most expensive assumption. Even if your supplier does not charge GST, you may still owe it.

Mistake 2: Missing RCM entries in GSTR-3B

Forgetting to declare reverse charge transactions triggers a mismatch between your GSTR-3B and the supplier’s GSTR-1 (if they ever register). This can lead to notices.

Mistake 3: Not paying RCM tax before the due date

Unlike forward charge where you file first and pay, for RCM under Section 9(4) you must pay tax before filing. The GST portal will not accept a GSTR-3B with RCM liability that exceeds the tax paid.

Mistake 4: Not claiming ITC on RCM tax paid

Many small businesses pay RCM tax but forget they can claim it as ITC in the same return. If the service is for your business, you can offset what you paid against your output tax liability.

Mistake 5: Wrong classification of services

RCM rates vary: 5% for GTA, 18% for most professional services. Using the wrong rate creates mismatches and potential penalty exposure.

Documents to Maintain for RCM Compliance

Keep these ready for each RCM transaction:

• Invoice or voucher from the supplier (even if it shows no GST)
• Payment proof (bank statement showing payment to supplier)
• Service agreement or contract (to show business purpose)
• RCM calculation worksheet (for your records during GST audit)

For GTA services specifically: the supplier’s GSTIN (if available), vehicle number, and freight amount.

ITC on RCM — What You Can and Cannot Claim

Situation	ITC claimable?
RCM paid on services used for business	Yes — in same GSTR-3B
RCM paid on goods/services for personal use	No
RCM paid on items blocked under Section 17(5)	No
RCM paid but not reported in GSTR-3B	No — must report to claim

ITC on RCM is claimed in Table 4(A)(2) of GSTR-3B for CGST/IGST. For SGST, you can claim it in the state return.

Special Cases for Gujarat Industries

Textiles and apparel (Surat, Ahmedabad)

Job work in textiles attracts RCM. If you are a garment trader in Surat and you get fabric processing done by an unregistered job worker, you pay GST under RCM.

Chemicals and petrochemicals (Vadodara, Bharuch)

Purchase of raw materials from unregistered suppliers triggers RCM. Chemical traders in Gujarat need to track this carefully — the RCM rate depends on the chemical type (5%, 12%, or 18%).

Diamond and gems (Surat)

B2B sales within the diamond trade often involve RCM when dealing with unregistered agents or small vendors. Surat’s diamond associations have specific guidance on this.

Maritime and ports (Mundra, Kandla, Bhavnagar)

Customs brokerage and freight services at Gujarat ports frequently involve RCM. If your business uses a customs broker who is unregistered, you pay GST under RCM.

GST Portal Warning Signs to Watch

Watch for these alerts in your GST dashboard:

• ITC mismatch: Your ITC claim exceeds what your supplier reported
• RCM liability mismatch: Portal shows RCM paid vs declared
• Annual return red flags: GSTR-9 highlights if RCM was not consistently reported

If you receive an ASCMT or DRC notice about RCM, do not ignore it. Read how to handle GST notices.

FAQs

Does reverse charge apply if my client is a proprietorship without GST?

Yes. Proprietorships without GST registration are treated as unregistered persons. If they pay you for a service, RCM applies at the rate for your service type.

I am a freelancer with turnover below ₹20 lakh. Do I need to pay RCM?

If your turnover is below ₹20 lakh and you are not registered under GST voluntarily, RCM does not apply to you. However, if you are registered voluntarily or your turnover exceeds the threshold, RCM rules apply on payments you receive from unregistered clients.

What happens if I forget to pay RCM tax?

Late payment attracts interest at 18% per annum from the due date. Persistent non-compliance can trigger GST officer scrutiny and penalty under Section 76 of the CGST Act.

Can I claim refund of RCM tax paid?

If you paid RCM tax but could not utilise the ITC (for example, due to exempt supplies), you may be able to claim a refund under certain conditions. Generally, ITC from RCM must be utilised within the prescribed time limits.

My client is registered but asks me not to charge GST. Is that legal?

If your client is GST-registered and you are also registered, normal forward charge applies — you must charge GST. Your client cannot ask you to waive this. Not charging GST on a registered B2B supply is a compliance violation.

How do I know if a service is under RCM?

Check Notification 33/2017-Central Tax (Rate) dated 13-10-2017 (as amended). Your CA or tax professional can also confirm for your specific service type. When in doubt, assume RCM applies until confirmed otherwise.

Is RCM applicable on goods purchased from unregistered dealers?

Yes. Under Section 9(4) of the CGST Act, RCM applies on supplies of goods from unregistered dealers to registered persons. The rate depends on the goods type. This is more common in B2B supply chains.
