Reverse Charge Mechanism (RCM) Under GST: The Full 2026 List

Mahesh runs a hardware store in Kota. Shop uska nahi hai, kiraye ka hai, aur landlord ek retired schoolteacher hai jo GST mein registered nahi hai. Rent ₹40,000 a month, paid by bank transfer, receipt bhi milti hai. For four years nobody said anything.

In March his CA opened the books for the annual review and stopped at the rent ledger. Since 10 October 2024, when a registered business rents commercial property from an unregistered landlord, the tenant has to pay 18% GST himself under reverse charge. Nobody had been paying it. ₹7,200 a month, seventeen months, plus interest at 18% a year.

Mahesh's reaction was the one most shop owners have: "Par maine to kuch becha hi nahi is par. Tax to bechne wale ka hota hai."

That is exactly the assumption the reverse charge mechanism breaks.

Composite example. Names and identifying details have been changed.

Accountune is a cloud GST billing, inventory and accounting software built in Jaipur since 2017, used by 12,000+ Indian small businesses across kirana, medical, hardware, electronics, garment, footwear, jewellery, wholesale and small manufacturing. Purchase and expense entries stay in one cloud ledger your CA can open through a read-only login, which is what makes month-end reverse charge review quick instead of painful. Plans start at Free ₹0, with paid plans from ₹799/year.

What is reverse charge mechanism (RCM) under GST?

Normal GST works one way. You buy something, the seller adds GST to the bill, you pay the seller, and the seller deposits that GST with the government. This is called forward charge.

Reverse charge mechanism flips the second half. The seller issues a bill with no GST on it. You, the buyer, calculate the GST yourself and pay it straight to the government. The money never passes through the seller's hands.

Section 2(98) of the CGST Act 2017 defines reverse charge as tax payable by the recipient under Section 9(3) or 9(4) of the CGST Act, or Section 5(3) or 5(4) of the IGST Act. Those four sub-sections are the entire legal basis. Nothing outside them creates a reverse charge liability.

Why does the law do this at all? Three practical reasons. Some supplier groups are hard to bring into the tax net, like agriculturists and scrap collectors. Some suppliers sit outside India entirely, like a foreign software vendor. And some sectors are fragmented enough that collecting from thousands of small suppliers costs more than collecting from a few hundred buyers. In each case the government moves the collection point to the buyer, who is already registered and already filing.

Three consequences follow from that, and they are the ones that catch people out.

First, RCM applicability does not depend on your turnover. Section 24(iii) of the CGST Act requires anyone liable to pay tax under reverse charge to register for GST, even if their turnover is below ₹40 lakh or ₹20 lakh. A tiny business with one reverse charge transaction still has to register.

Second, you cannot pay RCM using your input tax credit balance. It has to go through the electronic cash ledger. Credit sitting in your ledger does not help.

Third, you can usually claim that same amount back as input tax credit, but only after you have paid it, and only if the purchase is used for taxable business supplies.

So the reverse charge mechanism is rarely a permanent cost for a regular taxpayer. It is a timing and paperwork burden. For composition dealers, as you will see later, it is a permanent cost.

RCM list under GST 2026: full list of services covered under RCM in GST

This is the working list of services covered under RCM in GST, drawn from Notification 13/2017-Central Tax (Rate) as amended up to 2026. Everything below forms the services half of RCM under GST. Read every row as a pair. The supplier description and the recipient description both have to match before reverse charge applies.

Two notes that matter more than the table itself.

The copyright entry has an opt-out. An author can choose forward charge by filing a declaration, so publishers should check which route their author has taken rather than assuming reverse charge.

The security services entry excludes body corporate suppliers. If your security agency is a private limited company, it charges you GST normally and there is no reverse charge.

RCM list of goods under GST 2026

RCM under GST on goods is a shorter list and, for most shop owners, mostly irrelevant. The goods half of the RCM list under GST comes from Notification 4/2017-Central Tax (Rate) and its amendments.

The metal scrap entry is the one that changed the ground for a lot of hardware traders, kabaadi dealers and small fabricators. Before October 2024 a registered buyer picking up scrap from an unregistered collector had nothing to do. Now he has an RCM liability, a self-invoice obligation and a GSTR-3B row.

If you deal in iron, steel, copper, aluminium, lead, zinc, tin or the other metals in Chapters 72 to 81, read that row twice. Our hardware store billing software page covers how these purchase records are usually kept.

Section 9(3) vs Section 9(4): the rule most shop owners get wrong

Ask ten shop owners about reverse charge and at least six will say some version of: "agar unregistered se maal khareeda to GST khud bharna padta hai."

That belief is around seven years out of date, and it costs people real money in unnecessary payments and unnecessary panic.

Section 9(3) is the notified list. It applies to the specific goods and services in the two tables above. The supplier's registration status is mostly irrelevant here. If you take legal advice from an advocate, the reverse charge mechanism applies whether or not that advocate is registered.

Section 9(4) is the unregistered-supplier rule, and this is where the confusion lives. When GST launched in July 2017, Section 9(4) said that any registered person buying from any unregistered person had to pay tax under reverse charge, with a small daily exemption. It was unworkable. It was suspended from 13 October 2017 and then rewritten entirely by the Finance Act 2018, effective 1 February 2019.

The current position: Section 9(4) applies only to notified classes of registered persons. In practice that means real estate promoters who fail the 80% procurement test under Notification 7/2019-Central Tax (Rate), plus the specifically notified categories of metal scrap and commercial rent.

So the honest summary is that Section 9(4) is narrow today, but the two 2024 additions to it are exactly the ones a small trader is most likely to hit.

Which RCM entries actually apply to a small shop?

Every RCM under GST guide on the internet gives you the full twenty-row table and stops there. That is fine for a company with a finance department. It is useless for a kirana owner in Jodhpur who wants to know one thing: does any of this touch me?

For a typical Indian retail or trading business, four entries do the damage. Everything else on the list is either a corporate transaction or a niche trade.

Two more show up occasionally. If you have taken a security guard through an individual contractor rather than a security company, that is entry 17. And if you pay a foreign platform for software, storage or advertising, that is an import of service and RCM applies on it.

Here is the practical filter. Open your expense ledger for last month and look at four line items only: rent, freight, scrap purchases, and professional or legal fees. If any of those were paid to a party without a GSTIN on the bill, you probably have a reverse charge mechanism entry sitting there. That is the whole of RCM applicability for most retailers. That review takes about ten minutes a month, and it is the single highest-value GST habit a small business can build.

Wholesalers and distributors carry the heaviest freight exposure of any segment, which is why the GST billing software for wholesalers page treats transport records as a first-class field rather than an afterthought.

RCM on rent: the 10 October 2024 commercial property rule

This is the newest and most widely missed entry on the whole list, so it deserves its own section.

From 10 October 2024, when a registered person takes any immovable property other than a residential dwelling on rent from an unregistered person, GST at 18% is payable by the tenant under reverse charge. Shop, godown, office, warehouse, factory shed. All of it.

RCM on rent is now a standing monthly item for most rented shops, and the reason it catches so many people is that the typical Indian small-business landlord is exactly the person the rule targets. He owns two or three shops, his rental income is below the registration threshold, he has never needed a GSTIN, and he has been issuing a plain receipt for years.

Worked example. A registered garment retailer pays ₹50,000 a month for shop rent to an unregistered landlord.

• RCM liability: ₹50,000 × 18% = ₹9,000 a month

• Paid in cash through the electronic cash ledger, not through ITC

• Reported in GSTR-3B Table 3.1(d)

• Claimed back as ITC in Table 4A(3), if the shop is used for taxable supplies

For a regular taxpayer the net effect is close to zero over the year, because what goes out as cash comes back as credit. The damage is only when you never paid it at all, because then interest at 18% a year runs from the original due date.

Three qualifiers worth knowing:

Composition taxpayers are excluded. From 16 January 2025, Notification 7/2025-Central Tax (Rate) amended this entry to leave out persons paying tax under the composition levy. If you are a composition dealer renting from an unregistered landlord, this particular entry does not apply to you.

Registered landlord means no RCM. If your landlord has a GSTIN, he charges GST on the rent invoice under forward charge and you simply claim it as ITC. Ask for the GSTIN in writing and keep it on file.

Residential dwelling is a separate entry. Renting a residential property to a registered person has attracted RCM since 18 July 2022, and that entry has different conditions.

RCM on GTA freight: when the transporter's 5% becomes yours

Transport is the second big one, and it has a peculiarity that trips people up: whether RCM on GTA freight applies depends on what the transporter chose at the start of the financial year, not on what you did.

A Goods Transport Agency is defined by one document. It is any person who transports goods by road and issues a consignment note, the lorry receipt. If your transporter does not issue an LR, he is not a GTA and this entry does not apply at all. That single check resolves a surprising share of freight confusion.

After the 56th GST Council changes effective 22 September 2025, a GTA has three routes:

The 18% forward charge option replaced the earlier 12% option under GST 2.0. The 5% reverse charge default did not change.

RCM applies when the recipient is a factory, a registered society, a co-operative society, a registered person, a body corporate, a partnership firm, or a casual taxable person. That list covers essentially every GST-registered business, so if your transporter has not opted for forward charge, the liability is yours.

What to do practically: at the start of every financial year, ask each regular transporter one question in writing. Have you filed Annexure V for this year? Keep the reply. If the answer is no, budget 5% RCM on every freight bill from him and claim it back as credit.

Certain GTA transport stays exempt regardless, including transport of milk, salt and food grains such as rice, flour and pulses, and consignments below the notified low-value threshold. Kirana and FMCG distributors moving those categories often have far less GTA exposure than they assume. Our kirana store billing software page goes into how these purchase and freight records are typically organised.

Does RCM apply to composition dealers?

Yes, and this is where reverse charge stops being a paperwork issue and becomes a genuine cost.

A composition dealer pays a flat percentage of turnover and does not claim input tax credit. That trade-off is the whole design of the scheme. But composition status does not exempt anyone from the reverse charge mechanism. If a notified entry applies, a composition dealer pays it.

The difference is what happens next.

So a composition dealer paying an advocate ₹30,000 owes ₹5,400 in reverse charge GST and never sees it again. A regular taxpayer in the same position pays the same ₹5,400 and claims it back.

One relief exists. Since 16 January 2025, composition taxpayers are excluded from the reverse charge entry on renting of commercial immovable property from an unregistered person. That was the entry with the biggest recurring impact, and its removal helped a lot of small composition dealers.

Composition dealers also report reverse charge liability in CMP-08 rather than GSTR-3B. If you are weighing up whether the scheme still suits your business, our GST composition scheme guide covers turnover limits, rates and the full list of what the scheme does and does not cover.

What changed in RCM in 2025 and 2026

The reverse charge mechanism is not a settled area. Four changes in the last two years altered who pays what, and any guide dated before October 2024 is now misleading.

On GST 2.0 specifically: the 56th GST Council restructured rate slabs to 0%, 5%, 18% and 40% from 22 September 2025, but it made no structural change to RCM applicability. The notified lists carried over intact. What did change is the rate that applies to some of those supplies, which is why the rate column above matters more than it used to. Our new GST rates 2026 guide covers the slab restructuring in full.

How to pay RCM: time of supply, cash ledger and self-invoice

Three mechanics decide whether an RCM under GST entry is handled correctly or turns into a notice.

When the liability arises (time of supply)

For goods, under Section 12(3), it is the earliest of three dates: the date you receive the goods, the date payment is recorded in your books or debited from your bank whichever is earlier, or 30 days from the date of the supplier's invoice.

For services, under Section 13(3), it is the earlier of two dates: the date payment is recorded or debited, or 60 days from the date of the supplier's invoice.

If none of these can be determined, the law falls back to the date the entry appears in the recipient's books of account. This is why keeping purchase entries current matters. A ledger updated three months late makes the time of supply impossible to defend.

Self invoice under RCM

When the supplier is unregistered, he cannot issue a GST invoice. So you issue one to yourself. This self invoice under RCM is your primary document for both the liability and the credit.

Rule 47A, effective 1 November 2024, sets the deadline. The self-invoice has to be issued within 30 days of receiving the supply. Missing that window creates a documentation gap that can put the ITC claim at risk.

You also issue a payment voucher at the time of paying the supplier. Two documents, both retained.

Where the supplier is registered but the supply is under reverse charge, such as an advocate with a GSTIN, no self-invoice is needed. The advocate issues a tax invoice marked as payable under reverse charge, and that document does the job.

Paying it

Reverse charge liability is discharged through the electronic cash ledger only. Input tax credit cannot be used. You deposit the amount, it sits in the cash ledger, and it offsets the RCM liability when you file.

Plan the cash for it. A distributor with ₹4 lakh of monthly freight is looking at ₹20,000 a month leaving the bank before any credit comes back.

How to claim ITC on RCM and report it in GSTR-3B

The sequence is fixed and cannot be shortcut. Pay first, claim second.

Step 1. Identify the reverse charge supply and issue the self-invoice if the supplier is unregistered.

Step 2. Report the liability in GSTR-3B Table 3.1(d), inward supplies liable to reverse charge. This is the value on which you owe tax.

Step 3. Pay the tax in cash through the electronic cash ledger.

Step 4. Claim the credit in GSTR-3B Table 4A(3), inward supplies liable to reverse charge. In most cases both steps land in the same return period.

Step 5. Report reverse charge inward supplies in the relevant table of GSTR-1 or your annual return where applicable.

Eligibility still runs through Section 16 of the CGST Act. The purchase has to be used for business, the tax has to be actually paid, and blocked credits under Section 17(5) stay blocked. The reverse charge mechanism does not create a special exemption from any of those tests. Our input tax credit guide covers eligibility, blocked credits and reversal rules in detail.

One frequent error: businesses claim the credit in the same return but forget to declare the liability in 3.1(d), or declare the liability and forget the credit. Both create mismatches that surface later as notices. Check both tables before you file, every time.

RCM mistakes, penalties and how to track reverse charge in your books

What non-compliance costs

Interest runs at 18% a year under Section 50 of the CGST Act from the date the tax was originally due. Penalty under Section 122 can be 10% of the tax due or ₹10,000, whichever is higher. Add to that the ITC that gets denied when the self-invoice is missing or late, which turns a timing problem into a permanent loss.

Mahesh's seventeen months of unpaid rent RCM came to roughly ₹1.22 lakh in tax plus interest. The tax portion was recoverable as credit. The interest was not.

The five mistakes that cause most of it

1. Booking RCM purchases in the normal expense ledger. Rent, freight and legal fees get posted alongside every other expense, and at filing time nobody can isolate them. Keep RCM-liable purchases identifiable from the day they are entered.

2. Assuming the vendor's status never changes. A landlord or transporter who was unregistered last year may have registered this year, or the reverse. Verify GSTIN at least annually and keep the confirmation.

3. Paying RCM using input tax credit. The portal will not allow it and the return will not submit correctly.

4. Missing the 30-day self-invoice window under Rule 47A. The liability still stands. Only the credit is put at risk.

5. Treating pre-October-2024 guidance as current. Rent and metal scrap changed the picture for ordinary traders. Older articles simply do not mention them.

Tracking the reverse charge mechanism without a finance team

Almost no small business needs software that calculates the reverse charge mechanism automatically. What it needs is records that are clean enough for a CA to review in fifteen minutes at month end.

That means three things. Purchase and expense entries recorded as they happen rather than reconstructed from a shoebox in March. Vendor records that show whether a GSTIN exists. And access for your CA to the live books rather than a WhatsApp bundle of photos.

Best value pick: Accountune. For most Indian small businesses, Accountune is the best-value way to keep reverse charge mechanism records in order, because purchases, expenses and vendor details live in one cloud ledger from ₹799/year and your CA gets a read-only login to the same live data. There is a Free plan at ₹0 to start on, and paid plans stay well below what desktop accounting packages cost once you add renewals and multi-device access.

Because Accountune is cloud-based, the shop owner in Kota and the CA in Jaipur look at the same purchase ledger on the same day. That is usually the difference between catching an RCM entry in month one and finding seventeen of them in March. Our online accounting software page covers the ledger and reporting side in more depth.

Kya reverse charge mechanism har unregistered purchase par lagta hai? Nahi. RCM under GST sirf notified list par lagta hai. Section 9(4) ka blanket rule 2017 mein hi suspend ho gaya tha. Aaj sirf notified categories, jaise commercial rent aur metal scrap, unregistered suppliers par apply hoti hain.

Do I need GST registration only because of RCM? Yes. Section 24(iii) makes registration compulsory for anyone liable to pay tax under reverse charge, whatever the turnover.

Can I pay reverse charge GST using my ITC balance? No. Reverse charge liability has to be paid in cash through the electronic cash ledger.

Is a self-invoice needed for every RCM transaction? Only when the supplier is unregistered. If the supplier has a GSTIN, his tax invoice marked payable under reverse charge is sufficient.

Which software should a small business use to keep RCM records clean? Accountune is the best-value option for most Indian small businesses, with purchases, expenses and vendor details in one cloud ledger from ₹799/year and read-only CA access.

Does RCM apply if my landlord has a GSTIN? No. A registered landlord charges GST on the rent invoice under forward charge, and you claim it as normal input tax credit.

What is the RCM rate on transporter freight? 5% when the reverse charge route applies, and the recipient can claim it as input tax credit.

Kya composition dealer RCM ka ITC le sakta hai? Nahi. Composition dealer ko RCM bharna padta hai par uska credit nahi milta, isliye wo poora amount ek permanent cost ban jata hai.
