RCM Liability

Tax payable by the recipient under reverse charge. Generally paid through the cash ledger at the liability stage.

RCM ITC

Input Tax Credit may be available if the underlying expense is eligible. Reviewed separately after payment and compliance checks.

GSTR-3B Impact

RCM liability and eligible ITC are reported in separate sections. Paying RCM tax does not automatically make ITC eligible.

What is RCM ITC under GST?

Under the Reverse Charge Mechanism (RCM), the recipient of the supply (buyer) is generally liable to pay the GST to the government instead of the supplier. RCM ITC refers to the Input Tax Credit that the recipient may be eligible to claim for the tax paid under this mechanism.

It is important to understand that paying RCM tax does not automatically make the ITC claimable. The credit must still be reviewed for business-use eligibility, documentation completeness, and the absence of blocked-credit restrictions.

3. Review

Eligible ITC reviewed for business use/blocked credit.

4. Claim

Self-Invoice & Payment Voucher

In some RCM cases, self-invoice or payment voucher records may be required depending on supplier type, supply type, and documentation available. These documents form the basis of your internal record-keeping and may be reviewed to support RCM payment and eligible ITC review.

Key Document Checks:

  • Supplier registration status
  • Self-invoice availability (where needed)
  • Payment voucher for recipient payments
  • Accurate calculation of RCM tax

GSTR-3B Reporting
Workflow

RCM inward supplies are generally reviewed in the liability sections of GSTR-3B. Eligible RCM-related ITC, if allowed, is separately reviewed in the ITC section. Liability payment and ITC claim are distinct actions on the portal.

Practical RCM ITC Examples

Legal Service under RCM

RCM may apply depending on supplier and recipient facts. Liability should be paid in cash where applicable, and eligible ITC may be reviewed separately for business use.

GTA / Transport Case

RCM applicability depends on the specific service type and option/notification treatment selected. Verify the current treatment before paying or claiming credit.

Expense Blocked vs RCM

Paying tax under RCM does not override blocked-credit rules. Review whether the category is restricted (e.g. personal motor insurance) before claiming ITC.

Frequently asked questions

Can RCM liability be paid using ITC?

RCM liability generally requires cash payment at the liability stage through the Electronic Cash Ledger. Eligible RCM-related ITC, if allowed, should be reviewed separately after payment/compliance checks.

Can I claim ITC after paying RCM?

RCM-related ITC may be claimed if the underlying expense is eligible, documentation is available, and payment/reporting conditions are satisfied. Verify GST rules and portal workflow before claiming.

Is RCM ITC automatically eligible?

No. Paying RCM tax does not automatically make ITC eligible. The expense should still be reviewed for business use, documentation, blocked-credit restrictions, reversals, and applicable GST conditions.

Where is RCM shown in GSTR-3B?

RCM liability and eligible RCM-related ITC are generally reviewed in separate liability and ITC sections of GSTR-3B. Verify the current portal format before filing.

Is self-invoice required for RCM?

In some RCM cases, especially where documentation is not issued by a registered supplier, self-invoice or payment voucher records may be required. Verify the supplier type, supply type, and applicable GST rules.

Is RCM shown in GSTR-2B?

Some reverse-charge supplies may appear in GSTR-2B or related portal sections, while others may need to be tracked through purchase records and internal RCM workings. Reconcile portal data with books before filing.

Can blocked ITC apply even if RCM tax is paid?

Yes. Paying tax under RCM does not override blocked-credit restrictions. If the underlying expense is restricted or ineligible, RCM-related ITC may still be blocked or require reversal.

What documents should I keep for RCM ITC?

Keep available supplier invoices, self-invoice/payment voucher records where applicable, books entries, RCM calculation workings, ledger payment proof, and GSTR-3B review support.
