GAAR: Applicability and Impermissible Avoidance Arrangement

Updated 11 October 2026 · Fact-checked

GAAR lets the tax authority declare an arrangement an impermissible avoidance arrangement (IAA) under sections 178 to 181 of the Income-tax Act, 2025. The arrangement's main purpose must be a tax benefit, and it must meet one of four tests in section 179(1). Then the tax consequences are re-determined.

Understand GAAR: Applicability and Impermissible Avoidance Arrangement

Tax planning is legal. Tax avoidance that abuses the law is not. GAAR is the Act's tool for catching arrangements that follow the letter of the law but defeat its purpose. Section 178(1) says that, irrespective of anything else in the Act, an arrangement entered into by an assessee may be declared an impermissible avoidance arrangement. Its tax consequences are then decided under this Chapter. Section 178(2) lets the Chapter apply to any step in, or part of, an arrangement, not only to the whole.

Section 179(1) defines an impermissible avoidance arrangement. It has two layers. First, the main purpose of the arrangement must be to obtain a tax benefit. Second, the arrangement must satisfy at least one of four tests: (a) it creates rights or obligations not ordinarily created between persons dealing at arm's length; (b) it results, directly or indirectly, in misuse or abuse of the Act's provisions; (c) it lacks commercial substance, or is deemed to lack it under section 180, in whole or in part; (d) it is entered into or carried out by means or in a manner not ordinarily employed for bona fide purposes.

The main purpose is easier for the department to establish than it looks. Section 179(2) creates a presumption. If the main purpose of a step or part of the arrangement is to obtain a tax benefit, the whole arrangement is presumed to have that main purpose, even if the whole is not tax-driven. The assessee can rebut this only by proving the contrary.

Section 180(1) lists when an arrangement is deemed to lack commercial substance. These are: (a) its substance or effect as a whole is inconsistent with, or differs significantly from, the form of its individual steps; (b) it involves round trip financing, an accommodating party, elements that offset or cancel each other, or a transaction through one or more persons that disguises the value, location, source, ownership or control of funds; (c) it involves the location of an asset, a transaction or a party's residence without substantial commercial purpose other than a tax benefit; (d) it has no significant effect on the business risks or net cash flows of any party, apart from the tax benefit.

Section 180(3) adds a safeguard. The period for which the arrangement exists, the fact that tax is paid under it, and the fact that it provides an exit route may be relevant, but none of them alone is sufficient to decide commercial substance. Section 181 then deals with consequences, covered in the next topic.

Key rules to remember

Applicability of GAAR: Section 178(1): an arrangement of an assessee may be declared an IAA, overriding anything else in the Act; section 178(2): the Chapter can apply to any step or part; Applies to a step or a part, not only the whole arrangement.
Impermissible avoidance arrangement: IAA = main purpose is a tax benefit AND at least one of tests (a) to (d) in section 179(1); Tests: non-arm's length rights or obligations; misuse or abuse of the Act; lack of commercial substance; non-bona fide means or manner.
Presumption of main purpose: Main purpose of a step or part is a tax benefit ⇒ whole arrangement presumed to have that purpose, unless the assessee proves otherwise; Section 179(2). The burden of rebuttal is on the assessee.
Deemed lack of commercial substance: Section 180(1): (a) substance differs from form; (b) round trip financing, accommodating party, offsetting elements, or disguised funds; (c) location without commercial purpose; (d) no significant effect on business risks or net cash flows; Condition (c) and (d) both exclude the tax benefit when judging purpose or effect.
Not sufficient alone: Period of existence, payment of taxes, and an exit route: relevant but not sufficient (section 180(3)); Use these as supporting factors only.

How to solve GAAR: Applicability and Impermissible Avoidance Arrangement questions

Use this order for any GAAR case question. It follows the exam format of provision, analysis, conclusion.

1Identify the arrangement and list its individual steps. Note which step gives the tax benefit and quantify the benefit.
2State section 178: the Chapter applies irrespective of other provisions and can apply to any step or part.
3Test the main purpose. Ask whether obtaining a tax benefit is the main purpose. Apply the section 179(2) presumption if any step or part has that purpose.
4Test each of the four limbs of section 179(1): arm's length rights, misuse or abuse, commercial substance, bona fide means or manner. One is enough.
5For commercial substance, run through section 180(1)(a) to (d) and section 180(2) for round trip financing. Use section 180(3) only as supporting factors.
6Check what the assessee can offer as rebuttal: genuine business reasons, real change in risks or cash flows.
7Conclude clearly: is it an IAA or not, and which limb applies. Mention that consequences follow under section 181.

Quickest way: Two-gate check

When to use it: Use when you have little time and the question simply asks whether an arrangement is an IAA.

Gate 1: write the tax benefit and say whether it is the main purpose (apply the step-level presumption).
Gate 2: pick the strongest limb of section 179(1) and tie one fact to it, such as round trip funds or a conduit entity.
Add one line on section 180(3): period, tax paid or exit route do not decide the matter alone.
Close with the conclusion and a mention of section 181.

Common mistakes in GAAR: Applicability and Impermissible Avoidance Arrangement

Saying any tax saving is an IAA.
Students forget that the main purpose and one of the four limbs are both required.
Fix: Always show both gates. Legitimate tax planning with real commercial substance is not caught.
Treating the four limbs as cumulative.
The list looks like a checklist where all must be met.
Fix: Section 179(1) uses 'or'. Meeting any one limb, along with the main purpose condition, is enough.
Ignoring the step-level presumption.
Students judge only the purpose of the whole arrangement.
Fix: Apply section 179(2): a tax-driven step can make the whole arrangement presumed tax-driven, unless the assessee proves otherwise.
Using tax paid, duration or an exit route as decisive.
These facts seem to show a genuine deal.
Fix: Section 180(3) says they may be relevant but are not sufficient. Look at substance, risks and cash flows.
Skipping the tax benefit in the commercial-purpose tests.
Students read section 180(1)(c) and (d) loosely.
Fix: Both ask whether the purpose or effect exists apart from the tax benefit. Remove the tax benefit, then see what remains.

Worked examples

Example 1

Aarav Traders Ltd, an Indian company, routes ₹2,00,00,000 to a group entity in a low-tax jurisdiction, which lends the same amount back within days. The entity has no staff or business. The arrangement's only aim is to create a deductible expense. Examine whether GAAR can apply.

Show the solution

Applicability: under section 178(1), the arrangement can be declared an IAA irrespective of other provisions of the Act.
Main purpose: the only aim is a tax benefit, so the first gate is met. Section 179(2) would also support the presumption.
Commercial substance: funds move among the parties in a series of transactions with no substantial commercial purpose other than the tax benefit. This is round trip financing under section 180(2). Section 180(2) applies whatever the tracing, timing or mode of the funds.
The entity with no business is also a likely accommodating party under section 180(1)(b)(ii). The arrangement also has no significant effect on business risks or net cash flows apart from the tax benefit (section 180(1)(d)).
So the arrangement is deemed to lack commercial substance, which meets section 179(1)(c).

Answer: The arrangement is an impermissible avoidance arrangement. The main purpose is a tax benefit and it lacks commercial substance through round trip financing and an accommodating party. Consequences follow under section 181.

Example 2

Meera Pharma Ltd sets up a new subsidiary in a state with a real plant, hires 120 staff and shifts production there. A tax incentive is one reason, but supply costs and market access are also major reasons. The arrangement has existed for only two years. Can the department declare it an IAA on the ground of short duration?

Show the solution

Main purpose: a tax incentive is one reason, but costs and market access are also major reasons. The assessee can show the main purpose is not the tax benefit.
Commercial substance: a real plant and 120 staff change business risks and net cash flows, so section 180(1)(d) is not met. Location has a commercial purpose, so section 180(1)(c) is not met either.
Duration: under section 180(3)(a), the period for which the arrangement exists may be relevant but is not sufficient to decide the lack of commercial substance.
No limb of section 179(1) is clearly satisfied, and the facts show a bona fide business arrangement.

Answer: Short duration alone cannot make it an IAA. The arrangement has real commercial substance and a genuine business purpose, so GAAR should not apply.

Exam tips

Write section references with each point: 178 for applicability, 179 for definition, 180 for commercial substance. This earns marks in case answers.
Always show both gates: main purpose, then one limb of section 179(1).
Name the exact section 180 factor from the facts, such as round trip financing or accommodating party, rather than saying 'no substance'.
State section 180(3) in any answer where facts mention duration, tax paid or exit.
End with a clear conclusion and mention section 181 for consequences.

GAAR: Applicability and Impermissible Avoidance Arrangement: frequently asked questions

What is section 178 of the Income-tax Act, 2025?

It sets out the applicability of GAAR. An arrangement entered into by an assessee may be declared an impermissible avoidance arrangement, irrespective of other provisions of the Act. The Chapter can also apply to any step or part of the arrangement.

What is an impermissible avoidance arrangement?

It is an arrangement whose main purpose is to obtain a tax benefit and which meets at least one test in section 179(1). The tests cover non-arm's length rights or obligations, misuse or abuse of the Act, lack of commercial substance, and non-bona fide means or manner.

When does an arrangement lack commercial substance?

Section 180(1) lists the cases. Examples are substance differing from form, round trip financing, an accommodating party, offsetting elements, disguised funds, location without commercial purpose, and no significant effect on business risks or net cash flows apart from the tax benefit.

Can the assessee rebut the main purpose presumption?

Yes. Section 179(2) presumes the main purpose is a tax benefit where a step or part has that purpose, but only unless the assessee proves the contrary. Evidence of genuine business reasons is the usual rebuttal.
