GST 2.0 Two-Tier Rates: What Intermediaries Must Know Now
The GST Council's shift to a 5% and 18% two-tier structure is not just a rate reshuffle — it rewrites the place of supply logic for intermediary services and redraws the export benefit map for Indian practitioners.
By the SuperAccountant Editorial Team
The Rate Change You Think You Understand — And Probably Don't
Most practitioners have already noted the headline: the GST Council has approved a two-tier rate structure collapsing the existing four-slab framework into a cleaner 5% and 18% architecture, eliminating the 12% slab and rationalising the 28% slab to a narrower set of demerit goods and luxury items. That part has been covered widely.
What has not been covered adequately is the simultaneous correction to the place of supply rule for intermediary services — and that correction has a direct, material consequence on whether your client's billing to a foreign principal qualifies as a zero-rated export of service or attracts 18% GST with no refund path. If you are advising any trading house, commission agent, freight forwarder, or back-office services firm billing overseas clients, this week's changes demand an immediate review of their invoicing structure and contract terms.
Why the 12% Slab Elimination Matters for Input Credits First
Before reaching the intermediary-specific issue, understand the mechanical impact of removing the 12% slab on input tax credit (ITC) chains.
Under the rationalised structure, goods and services that sat at 12% will migrate either to 5% or 18%. Where a supplier's output moves to 5% and their inputs remain at 18%, the inverted duty structure refund under Section 54(3) of the CGST Act becomes relevant. The GST Council has simultaneously approved that provisional refunds under the inverted duty structure will be disbursed at 90% of the claimed amount, consistent with Rule 91 of the CGST Rules, reducing the working capital strain that practitioners have long flagged.
Practical example: A food processing unit buys packaging material at 18% GST and sells its finished product at 5%. On a monthly procurement of ₹50 lakh, the ITC accumulation at 18% (₹9 lakh) outpaces output tax at 5% (₹2.5 lakh on ₹50 lakh turnover). Under Rule 91, 90% of the net accumulated ITC — here approximately ₹5.85 lakh — is released provisionally within 7 days of acknowledgement of the refund application in Form GST RFD-02. The remaining 10% is released after scrutiny.
For your manufacturing clients straddling the newly drawn slab lines, the first task this week is to reclassify all input and output items under the revised rate schedule and model the revised ITC accumulation. Do not wait for your client's next refund cycle to discover a structural shortfall.
The Intermediary Services Problem: A History of Distortion
Now to the issue that competing commentary has largely skipped.
Section 13(8)(b) of the IGST Act defines the place of supply for intermediary services as the location of the supplier — not the location of the service recipient. This rule has been the source of sustained litigation and practical hardship. An Indian commission agent facilitating a sale between a foreign buyer and a foreign seller has, under this provision, been treated as supplying a service in India (because the agent is located in India), making the supply a domestic supply taxable at 18%, not a zero-rated export.
The Supreme Court in the past addressed connected questions around the IGST Act's intermediary provisions, and the CBIC has issued clarifications (Circular No. 159/15/2021-GST dated 20 September 2021, available at cbic-gst.gov.in) that attempted to narrow the scope of who qualifies as an intermediary. However, the core distortion in Section 13(8)(b) remained unaddressed by statute.
The GST 2.0 reform package now proposes to amend Section 13(8)(b) to align the place of supply for intermediary services with the location of the recipient of services — consistent with the general rule under Section 13(2) of the IGST Act. This is the correction practitioners have been requesting since 2017.
What the Recipient-Location Rule Changes in Practice
The shift from supplier-location to recipient-location as the place of supply trigger for intermediary services has three immediate consequences:
| Scenario | Under Old Sec 13(8)(b) | Under Proposed Amendment |
|---|---|---|
| Indian agent, foreign principal (service recipient outside India) | Place of supply = India → 18% IGST, no export benefit | Place of supply = outside India → zero-rated export under Sec 16(1)(a) IGST Act |
| Indian agent, Indian principal (both in same state) | Place of supply = India → CGST + SGST applicable | No change — place of supply remains India |
| Indian agent, Indian principal (different states) | Place of supply = India → IGST applicable | No change — place of supply remains India |
Practical consequence for your client's workflow:
A Mumbai-based logistics coordination firm earning commission of ₹25 lakh per quarter from a German freight principal currently raises invoices with 18% IGST (₹4.5 lakh), which the Indian firm cannot recover as a refund because the supply is treated as domestic. Under the amended rule, the same invoice would qualify as an export of service under Section 2(6) of the IGST Act — zero-rated, with the firm eligible to either claim a refund of ITC under Section 54(3) or supply under a Letter of Undertaking (LUT) without payment of tax. The quarterly cash flow differential here is ₹4.5 lakh. Annualised, this is ₹18 lakh — material for any mid-size intermediary.
The preconditions for zero-rating remain: the supply must be to a person located outside India, payment must be received in convertible foreign exchange (or Indian rupees where permitted by the RBI), and the recipient and supplier must not be mere establishments of the same entity as per Explanation 1 to Section 8 of the IGST Act.
Contract and Invoice Restructuring: What to Do This Week
The statutory amendment requires enactment and notification before it takes legal effect. Practitioners should not alter client invoices in anticipation of an amendment that has not yet been notified in the Official Gazette. However, the preparatory work must begin now.
Checklist for intermediary service clients:
- Identify all contracts where your client acts as a commission agent, broker, or intermediary for a foreign principal and currently bears 18% IGST with no recovery path.
- Review contract definitions — confirm whether the client's role is that of a principal buying and reselling, or a true intermediary facilitating a transaction between two other parties. The CBIC Circular 159/15/2021 drew this line carefully; revisit that analysis.
- Verify foreign exchange receipt documentation — FIRC (Foreign Inward Remittance Certificate) or bank credit confirmation is required for zero-rating. Many intermediary firms collect payment through netting arrangements that do not produce clean FIRC documentation.
- Prepare LUT filing in Form GST RFD-11 on the GST portal for the relevant financial year as soon as the amendment is notified. Supplies made under LUT after notification will be zero-rated without upfront tax payment.
- Model the ITC refund claim — once zero-rated, ITC on inputs (office rent at 18%, professional services at 18%, software subscriptions at 18%) becomes refundable. Quantify this before the notification so refund applications are filed promptly.
- Alert clients on the 2-year limitation under Section 54(1) of the CGST Act for refund claims. If prior periods are partially reclaimable after the amendment (subject to legal interpretation and any retrospective application, which has not been signalled), track the time window carefully.
If you want a structured diagnostic to test your understanding of these rules before advising clients, the SuperAccountant GST quiz covers place of supply scenarios including intermediary edge cases — worth 15 minutes before your next client call.
The Inverted Duty Structure Refund Acceleration: Operational Detail
The 90% provisional refund approval under Rule 91 applies where the refund claim is on account of accumulated ITC due to an inverted rate structure. The CBIC processes the provisional order within 7 days of issuance of the acknowledgement in Form GST RFD-02. The jurisdictional officer then issues Form GST RFD-04 for the provisional amount.
Key conditions that disqualify a claim even under the accelerated track:
- ITC attributable to exempt supplies must be excluded per Rule 89(5) of the CGST Rules.
- ITC on capital goods is not eligible for refund under Section 54(3) — only input goods and input services qualify.
- Supplier defaults captured in GSTR-2B that have not been reversed under Section 16(2)(c) of the CGST Act will reduce eligible ITC and create scrutiny risk.
For clients in sectors now migrating to the 5% output slab (certain processed food products, specified healthcare items), model the Rule 89(5) restriction carefully. The maximum refund is capped at the formula: [Turnover of inverted rated supply of goods and services ÷ Adjusted total turnover] × Net ITC — this is not the full accumulated ITC balance.
The Broader GST 2.0 Context: What Else to Watch
The two-tier rate rationalisation and the intermediary place of supply correction are part of a broader GST 2.0 reform agenda that also includes:
- Decriminalisation amendments reducing compounding thresholds under Section 132 of the CGST Act.
- Strengthening of e-invoice applicability — the threshold has progressively reduced and the CBIC continues to push towards universal e-invoicing coverage.
- Revision to the composition scheme eligibility and rate thresholds.
Stay current with official notifications at cbic-gst.gov.in. The rate rationalisation and place of supply amendments will be effective only from the date of the relevant CGST Amendment Act gazette notification — do not act on the Council's approval alone.
For practitioners looking to build a practice around GST advisory — particularly the intermediary and cross-border space where complexity commands fees — the structured path is through supervised workpaper experience, not solo self-study.

Bottom Line for This Week
The two-tier rate structure story is primarily a rate reclassification exercise for most practitioners. For those with intermediary service clients billing foreign principals, the place of supply amendment is the more consequential change — potentially converting a fully taxed domestic supply into a zero-rated export and unlocking substantial ITC refunds. Begin the contract review, prepare the LUT filings, and model the refund quantification now. The amendment clock starts from gazette notification, not Council approval.
