RCM on security services: proprietorship vs corporate suppliers, rates, and GSTR-2B matching

Accounting departments regularly encounter conflicting invoices from security service vendors. A factory or corporate office hiring security guards may receive a tax invoice with 18% GST from one vendor, while another vendor charges base fees with no tax line. Understanding the target keyword rules for rcm on security services personnel supplier type individual vs corporate ensures that your business complies with statutory payment mandates and avoids unexpected tax demands, interest under Section 50, or audit notices in Form GST DRC-01C.

Statutory framework: Entry 14 of Notification No. 13/2017-Central Tax (Rate)

Reverse charge on security personnel is governed by Entry 14 of Notification No. 13/2017-Central Tax (Rate), which was inserted by Notification No. 29/2018-Central Tax (Rate) with effect from 1 January 2019 under the authority of Section 9(3) of the CGST Act.

Entry 14 sets out three simultaneous statutory tests that determine whether reverse charge applies:

• Nature of service: Security services provided by way of supply of security personnel. The service must consist of providing human guards, watchmen, or security staff.
• Constitution of the supplier: Any person other than a body corporate. This category covers sole proprietorships, partnership firms, Hindu Undivided Families (HUFs), and associations of persons (AOPs).
• Status of the recipient: A registered person located in the taxable territory.

“Security services (services provided by way of supply of security personnel) provided to a registered person: Provided that nothing contained in this entry shall apply to, (i)(a) a Department or Establishment of the Central Government or State Government or Union territory; or (b) local authority; or (c) Governmental agencies; which has taken registration... only for the purpose of deducting tax under section 51... (ii) a registered person paying tax under section 10 of the said Act. Any person other than a body corporate | A registered person, located in the taxable territory.” Entry 14 of Notification No. 13/2017-Central Tax (Rate) as inserted by Notification No. 29/2018-Central Tax (Rate)

When all three statutory criteria are met, the supplier cannot collect GST from the recipient. Liability shifts entirely to the registered recipient, who must calculate and pay the tax directly to the government treasury.

Supplier constitution test: proprietorship vs corporate entity

The legal constitution of the supplier decides whether tax falls under forward charge or reverse charge. Section 2(20) of the Companies Act, 2013, read with Section 2(11) of the CGST Act, defines a body corporate as a company incorporated under Indian company law or foreign law, including Limited Liability Partnerships (LLPs). It excludes sole proprietorships, traditional partnership firms, and societies.

Review the distinction in practice. When your facility hires guards from a national security corporation structured as a private limited or public limited company, the vendor issues a standard forward charge tax invoice charging 18% GST. You pay the tax to the supplier, and the invoice flows into your GSTR-2B after the supplier files Form GSTR-1. In contrast, when you contract with a local proprietorship agency or partnership firm, the vendor must not charge tax. Your accounts team must pay the 18% GST under reverse charge.

Statutory exclusions where reverse charge does not apply

Entry 14 carves out two express statutory exceptions where registered recipients do not pay reverse charge on security personnel:

1. Government departments registered solely for TDS: A department or establishment of Central or State Government, local authority, or governmental agency that holds GST registration solely to deduct tax at source under Section 51, and makes no independent commercial supplies.
2. Composition scheme taxpayers: Small businesses registered under Section 10 paying tax under the composition levy are exempt from paying RCM on inward security personnel supplies.

In addition, when a non-body corporate security vendor supplies guards to an unregistered individual or unregistered business establishment, reverse charge cannot apply because the recipient lacks GST registration. In that case, if the vendor crosses the ₹20,00,000 threshold for services, the vendor must obtain registration and pay GST under forward charge.

Tax rate, SAC code 9985, and self-invoicing mandates

Security services fall under Services Accounting Code (SAC) 9985 (support services). Under Heading 9985 of Notification No. 11/2017-Central Tax (Rate), security services attract a combined GST rate of 18% (comprising 9% CGST plus 9% SGST for intra-state supplies, or 18% IGST for inter-state supplies).

Documentation requirements depend directly on the registration status of the non-body corporate vendor:

Registered non-body corporate supplier: The supplier issues an invoice under Section 31 containing its GSTIN, the recipient GSTIN, and the description of personnel supplied. The supplier must mark the reverse charge indicator as YES and leave the tax rate and tax amount blank or zero. This vendor invoice forms your primary accounting voucher.

Unregistered security contractor: Small security agencies often operate below the threshold and have no GST registration. Under Section 31(3)(f) of the CGST Act read with Rule 36(1)(b) of the CGST Rules, the registered recipient must issue a self-invoice on the date of receiving the service. In addition, under Section 31(3)(g), the recipient must issue a payment voucher at the time of making payment to the supplier. The self-invoice is your statutory tax-paying document for claiming input tax credit.

Cash ledger settlement and input tax credit rules

Settling reverse charge tax on security services is governed by strict statutory rules under Section 49 and Section 16:

First, under Section 49(4) of the CGST Act read with Section 2(82), balance in your electronic credit ledger can be utilised only toward payment of output tax. Output tax is defined in Section 2(82) as excluding tax payable on reverse charge. Consequently, an accounts team cannot set off security RCM liability using accumulated input tax credit. The tax must be paid in cash via the electronic cash ledger.

Second, after paying the tax in cash, can the company recover it as credit? Yes. Under Section 2(62), input tax includes tax payable under Section 9(3). Under Section 16(1) of the CGST Act, registered persons are entitled to take credit of input tax charged on supplies used or intended to be used in the course or furtherance of business. Security protection for office premises, warehouses, and factories is directly connected to business operations, qualifying for full credit.

Third, under Section 16(2)(c), credit is allowable when the tax charged on the supply has actually been paid to the government. Because the recipient discharges this liability in Form GSTR-3B for the given month, the recipient is legally entitled to take credit in Table 4(A)(3) of the very same monthly return.

Fourth, while the second proviso to Section 16(2) requires recipient payments to suppliers within 180 days to preserve ITC, the statute explicitly carves out supplies on which tax is payable on reverse charge.

Step-by-step reporting workflow in Form GSTR-3B and GSTR-2B

To record security personnel inward supplies cleanly, follow this five-stage accounting procedure:

1. Verify vendor legal structure: Inspect the vendor PAN or registration document. If the fourth character of the vendor PAN is P (individual or proprietorship) or F (partnership firm), mark the vendor in your ERP as subject to RCM. If the fourth character is C (company), record the vendor under forward charge.
2. Raise self-invoice and payment voucher: For unregistered agencies, generate a self-invoice under Section 31(3)(f) with a unique serial number, and generate a payment voucher under Section 31(3)(g) upon disbursement.
3. Declare liability in GSTR-3B Table 3.1(d): On the GST portal, report the taxable value and the computed 18% GST in Table 3.1(d) (Inward supplies liable to reverse charge). Detailed navigation is outlined in the official GSTN Form GSTR-3B manual.
4. Discharge liability through cash ledger: In Table 6 of Form GSTR-3B, offset the reverse charge tax liability exclusively through cash ledger balances. Generate a challan in Form GST PMT-06 if cash balances are insufficient.
5. Avail credit in GSTR-3B Table 4(A)(3): In the same return, claim the paid tax under Table 4(A)(3) (Inward supplies liable to reverse charge). This instantly restores your electronic credit ledger for offsetting forward output tax.

Worked rupee example: proprietorship agency vs corporate contractor

To see how supplier constitution alters accounting entries, consider Apex Engineering Private Limited, an industrial components manufacturer in Pune, Maharashtra. During September 2026, the company engages two distinct security agencies to protect separate facility gates:

• Contractor A: Maratha Security Guard Force, a sole proprietorship firm. Monthly billing: ₹1,00,000.
• Contractor B: Shieldforce Protection Private Limited, an incorporated body corporate. Monthly billing: ₹1,00,000.

The comparative financial outcome illustrates key operational differences:

• For Maratha Security (proprietorship), Apex Engineering pays ₹1,00,000 to the vendor. Apex then pays ₹18,000 in cash to the government in Form GSTR-3B Table 6, and simultaneously claims ₹18,000 in Table 4(A)(3). Working capital outflow to the treasury is ₹18,000, recovered immediately as credit ledger balance.
• For Shieldforce Protection (private limited), Apex Engineering pays ₹1,18,000 directly to the vendor. Once Shieldforce files Form GSTR-1, the invoice appears in Apex's GSTR-2B under B2B supplies, auto-populating Table 4(A)(5) of Form GSTR-3B. Apex pays zero cash to the government.
• In both cases, net expense for the company is ₹1,00,000. However, the cash flow timing, invoice documentation, and GSTR-3B table reporting diverge completely based on supplier legal status.

GSTR-2B reconciliation and audit scrutiny risks

Reconciling security services against monthly Form GSTR-2B requires addressing two specific audit traps:

Case 1: Vendor is registered but fails to mark reverse charge. If a proprietorship vendor files Form GSTR-1 but mistakenly marks Reverse Charge = N, the invoice will populate in your GSTR-2B under regular B2B supplies rather than inward reverse charge. If your accounts team blindly accepts this auto-population into Table 4(A)(5) without paying cash in Table 3.1(d), tax authorities will issue a demand under Section 73 or Section 74 for unpaid RCM along with 18% annual interest under Section 50(1). Your team must instruct the vendor to amend the record in Form GSTR-1A or the subsequent tax period.

Case 2: Vendor is unregistered. Unregistered proprietorship security bills will never appear in Form GSTR-2B. Your accounting software must track these internal vouchers independently. Do not wait for an invoice to arrive in GSTR-2B before reporting RCM liability in Table 3.1(d). Failing to declare unregistered RCM in the month of service receipt delays cash tax deposit, exposing the business to mandatory interest.
