Safe Harbour Rules in India: Rule 10TD Guide
The Indian Safe Harbour Rules (Rule 10TA-10TE) — eligible international transactions, prescribed margins as amended to 2025, and how to elect via Form 3CEFA.
Safe Harbour Rules let an eligible assessee declare a transfer price within prescribed circumstances and have that price accepted by the tax authorities without a comparability fight. They are the only route in Indian transfer pricing to genuine pricing certainty: no Accept-Reject matrix, no TPO scrutiny of the comparable pool, no range to defend.
The regime sits in Rule 10TA–10TE of the Income-tax Rules, 1962, given effect by section 92CB of the Income-tax Act. Rule 10TC lists the eligible international transactions and Rule 10TD prescribes the circumstances (margins/rates) at which the declared price is accepted.
What changed in 2025
The Income-tax (6th Amendment) Rules, 2025 — Notification 21/2025 dated 25 March 2025 — extended the regime and widened access:
- Threshold increased from ₹200 crore to ₹300 crore for the services eligible under sub-rule (2A) (software development, ITeS, KPO, contract R&D).
- Applicability extended to assessment years 2025-26 and 2026-27, with the option valid for one assessment year at a time under Rule 10TD(3B).
- Lithium-ion batteries added to the definition of “core auto components” (eligible for the 12% manufacturing safe harbour).
Eligible transactions and prescribed circumstances
| Eligible international transaction (Rule 10TC) | Safe harbour (Rule 10TD) |
|---|---|
| Software development services | OP/OC ≥ 17% (≤ ₹100 cr); ≥ 18% (> ₹100 cr, ≤ ₹300 cr) |
| IT-enabled services (ITeS) | OP/OC ≥ 17% (≤ ₹100 cr); ≥ 18% (> ₹100 cr, ≤ ₹300 cr) |
| Knowledge process outsourcing (KPO) | OP/OC ≥ 18%–24% depending on the employee-cost ratio |
| Contract R&D (software) | OP/OC ≥ 24% (≤ ₹300 cr) |
| Contract R&D (generic pharma) | OP/OC ≥ 24% (≤ ₹300 cr) |
| Intra-group loans (INR) | SBI 1-year MCLR as on 1 April + 175–625 bps by credit rating |
| Intra-group loans (foreign currency) | Currency reference rate (SOFR/EURIBOR/SONIA etc.) + 150–600 bps |
| Corporate guarantee | Fee ≥ 1% per annum of the amount guaranteed |
| Low value-adding intra-group services | Margin ≤ 5% on total value (≤ ₹10 cr) |
| Manufacture & export of core auto components | 12% of operating cost (non-core: 8.5%) |
OP/OC means operating profit margin on operating costs as defined in Rule 10TA. For KPO, the prescribed margin tiers by employee cost as a ratio of operating costs — a genuinely knowledge-heavy entity qualifies at the higher end.
Who can elect — and how
An eligible assessee is a person who has entered into an eligible international transaction and has validly opted in under Rule 10TE. Election is made by filing Form 3CEFA electronically in the prescribed time before the due date of the return of income. Once validly exercised, the option stays in force for the period stated in the form (or three years, whichever is less) — but under sub-rule (3B) the option is exercised per assessment year.
Benefits and trade-offs
| Benefit | Trade-off |
|---|---|
| Pricing certainty — authorities accept the declared price | Prescribed margins may be lower than what an aggressive benchmark would support |
| No comparability dispute, shorter assessment | Option generally blocks a subsequent TP adjustment below the harbour |
| Lower documentation burden for the covered transaction | Safe Harbour documentation obligations still apply (Form 3CEFA records, related-party loan/guarantee particulars) |
| Removes the “wrong pool” risk | Once the option is exercised, you are bound to the harbour for the election period |
The trade-off is real: safe harbours are a floor-and-settlement instrument, not an optimisation tool. For a KPO operating at 30% OP/OC, electing at 24% leaves return on the table. For a routine ITeS provider facing an uncertain pool, certainty at 17–18% can be cheaper than defending a matrix.
When it makes sense
- Routine, low-margin services where the comparative pool is noisy or thin.
- Smaller transactions where the cost of building and defending a full Accept-Reject matrix exceeds the pricing gain.
- Cross-border structures where certainty in India matters more than squeezing the last basis point of arm’s-length margin.
Before electing, run the benchmark anyway: the decision should be made knowing where the arm’s-length range sits versus the harbour margin, not in the dark. That is exactly the comparison TP Analytics produces — the full range under Rule 10D, and the harbour margin alongside it.
Compare your range with the safe harbour before you elect
TP Analytics computes your arm's-length range and surfaces the Rule 10TD harbour margin side by side, so the election decision is a calculation, not a guess.
