Impermissible Avoidance Arrangement under GAAR Explained

Updated 11 October 2026 · Fact-checked

An impermissible avoidance arrangement (section 179, Income-tax Act, 2025) is an arrangement whose main purpose is to obtain a tax benefit and which also meets at least one tainted test: non-arm's length rights or obligations, misuse or abuse of the Act, lack of commercial substance, or non-bona fide means or manner. Apply the main purpose test first, then the four tests.

Understand Impermissible Avoidance Arrangement

GAAR is the General Anti-Avoidance Rule. It lets the tax authorities look past a structure that follows the letter of the law but defeats its purpose. Section 178 says that, irrespective of anything else in the Act, an arrangement may be declared an impermissible avoidance arrangement, and the tax consequences then determined. It can be applied to the whole arrangement or to any step or part of it.

Section 179(1) gives a two-part definition. First, the main purpose of the arrangement must be to obtain a tax benefit. Second, the arrangement must also satisfy at least one of four tainted elements:

  • it creates rights or obligations not ordinarily created between persons dealing at arm's length;
  • it results, directly or indirectly, in misuse or abuse of the provisions of the Act;
  • it lacks commercial substance, or is deemed to lack it under section 180, in whole or in part;
  • it is entered into or carried out by means or in a manner not ordinarily employed for bona fide purposes.

A tax benefit alone is not enough. Ordinary tax planning that has a real business purpose is not caught. You need both the purpose and a tainted element.

The law also helps the department on purpose. Under section 179(2), 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 by proof. So the burden shifts to you as the assessee.

Section 180 lists when an arrangement is deemed to lack commercial substance. These include: the substance differs significantly from the form of its steps; round trip financing; an accommodating party; elements that offset or cancel each other; a transaction through one or more persons that disguises the value, location, source, ownership or control of funds; location of an asset, transaction or residence without substantial commercial purpose other than a tax benefit; and no significant effect on business risks or net cash flows of any party apart from the tax benefit.

Key rules to remember

Definition test (section 179(1))
Impermissible avoidance arrangement = Main purpose is a tax benefit AND at least one of four tainted elements
Both parts are needed. The four elements are non-arm's length rights or obligations, misuse or abuse, lack of commercial substance, and non-bona fide means or manner.
Presumption of main purpose (section 179(2))
Main purpose of a step or part is a tax benefit ⇒ whole arrangement presumed tax-driven, unless the assessee proves otherwise
Applies even if the main purpose of the whole arrangement is not a tax benefit. The burden is on the assessee.
Round trip financing (section 180(2))
Series of transactions + funds transferred among the parties + no substantial commercial purpose other than a tax benefit
Tracing of funds, timing or sequence, and the mode of transfer are disregarded.
Factors not sufficient alone (section 180(3))
Duration of arrangement, payment of taxes, and an exit route are relevant but not sufficient
A long-running arrangement or one that pays tax can still lack commercial substance.
Test of effect (section 180(1)(d))
No significant effect on business risks or net cash flows, apart from the tax benefit ⇒ deemed lack of commercial substance
Use this for arrangements that change nothing economically.

How to solve Impermissible Avoidance Arrangement questions

Use this order for any case-based question on whether an arrangement is an impermissible avoidance arrangement.

  1. 1List the facts: the parties, each step, the money flows and the tax benefit obtained.
  2. 2Apply the main purpose test. Ask whether obtaining a tax benefit is the main purpose. Check section 179(2): if any step is tax-driven, the presumption covers the whole arrangement.
  3. 3Test each of the four tainted elements in section 179(1) one by one, and name the ones met.
  4. 4If lack of commercial substance is argued, check the section 180(1) triggers: form versus substance, round trip financing, accommodating party, offsetting elements, disguised funds, location without commercial purpose, no effect on risks or cash flows.
  5. 5Note section 180(3): duration, tax paid and an exit route are not enough on their own to decide.
  6. 6Conclude whether the arrangement can be declared impermissible, and state that the declaration follows the procedure of section 274 and the Approving Panel.
  7. 7Mention the consequences in section 181 briefly, such as disregarding steps, if the question asks for them.

Quickest way: Purpose first, then four tests

When to use it: Use for MCQs and short case scenarios where you must decide quickly whether GAAR applies.

  1. Underline the tax benefit in the facts. If no tax benefit exists, GAAR does not arise.
  2. Ask: is there a real business reason? If yes and strong, the main purpose test usually fails.
  3. Scan for keywords: circular funds (round trip), middleman with no role (accommodating party), steps that cancel out, no change in risk or cash flow.
  4. If you spot any one tainted element along with a tax-driven purpose, answer that it is an impermissible avoidance arrangement.

Common mistakes in Impermissible Avoidance Arrangement

  • Saying any arrangement that saves tax is impermissible.

    Students stop at the tax benefit and skip the second part of the definition.

    Fix: Always show both limbs: main purpose of a tax benefit and at least one tainted element.

  • Treating the four tainted elements as cumulative.

    The list looks like a checklist where all items must be met.

    Fix: They are alternatives joined by 'or'. Meeting one is enough, along with the main purpose.

  • Ignoring the presumption in section 179(2).

    Students judge the arrangement only as a whole.

    Fix: If one step is tax-driven, the whole is presumed tax-driven until the assessee proves otherwise.

  • Believing a long-running or tax-paying arrangement is safe.

    It seems logical that genuine arrangements last long and pay tax.

    Fix: Section 180(3) says duration, payment of taxes and an exit route may be relevant but are not sufficient.

  • Limiting round trip financing to funds that can be traced back.

    The name suggests money returning to the same source.

    Fix: Section 180(2) disregards traceability, timing or sequence, and the mode of transfer. The test is circular movement without substantial commercial purpose other than a tax benefit.

  • Confusing GAAR with evasion.

    Both involve reducing tax.

    Fix: Evasion is illegal, using false facts or concealment. GAAR targets arrangements that are legal in form but lack substance. Avoidance is declared impermissible, not necessarily unlawful concealment.

Worked examples

Example 1

Indian company A Ltd lends ₹2,00,00,000 to its subsidiary B Ltd. B Ltd lends the same amount to a shell entity C, which routes it back to A Ltd as share capital within the same month. The only outcome is a tax benefit for A Ltd. There is no change in the business of any party. Can the arrangement be an impermissible avoidance arrangement?

Show the solution
  1. Tax benefit: A Ltd obtains a tax benefit, and no other outcome exists. So the main purpose is a tax benefit.
  2. Funds move among the parties in a circle and return to A Ltd. This is round trip financing under section 180(1)(b)(i) and section 180(2), as there is no substantial commercial purpose other than the tax benefit.
  3. C acts only as a conduit, so it may also be an accommodating party.
  4. The arrangement has no significant effect on business risks or net cash flows apart from the tax benefit, which is section 180(1)(d).
  5. Therefore it lacks commercial substance, which is a tainted element under section 179(1)(c).

Answer: Yes. The main purpose is a tax benefit and the arrangement lacks commercial substance (round trip financing, accommodating party, no effect on risks or cash flows). It can be declared an impermissible avoidance arrangement through the procedure under section 274.

Example 2

X Ltd sets up a new unit in a backward area for genuine business reasons such as raw material access and lower costs. The unit also qualifies for a tax incentive. Separately, one step in the plan, a leasing contract with a related party, is designed mainly to save tax. The arrangement has been running for six years and X Ltd pays tax regularly. Examine the position.

Show the solution
  1. Main purpose of the whole arrangement: genuine business reasons, so the whole may not be tax-driven.
  2. Section 179(2): if the main purpose of a step or part is a tax benefit, the whole arrangement is presumed tax-driven, unless X Ltd proves otherwise. The leasing step triggers this presumption.
  3. X Ltd must prove that the main purpose is not a tax benefit, using the commercial reasons for the unit.
  4. Under section 178(2), GAAR can be applied to the leasing step alone. If it creates rights not ordinarily created at arm's length or lacks commercial substance, that part can be declared impermissible.
  5. Six years of operation and regular tax payment are not sufficient to defend it, as section 180(3) says.

Answer: The tax-saving leasing step brings in the presumption of section 179(2), so X Ltd bears the burden of rebuttal. The genuine unit is likely safe, but the leasing step can be examined and declared impermissible if a tainted element is met. Duration and tax payment do not protect it by themselves.

Exam tips

  • Write the definition in two limbs every time: main purpose plus one tainted element. Examiners reward this structure.
  • Quote the section numbers 178, 179, 180 and 181 in case answers, and 274 for procedure.
  • Learn the section 180(1) triggers as a list. MCQs often ask which factor is not sufficient on its own: duration, tax payment or exit route.
  • For case questions, name the exact tainted element from the facts, not just 'GAAR applies'.
  • Keep one line ready on avoidance versus evasion: evasion uses illegal means, GAAR targets arrangements that are legal in form.

Impermissible Avoidance Arrangement: frequently asked questions

What is an impermissible avoidance arrangement under the Income-tax Act, 2025?

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

What is lack of commercial substance under GAAR?

Section 180 lists the cases. Examples are where substance differs significantly from form, round trip financing, an accommodating party, offsetting elements, or no significant effect on business risks or net cash flows apart from the tax benefit. Location of an asset or residence without a commercial purpose other than a tax benefit is also covered.

What is the difference between tax avoidance and tax evasion in GAAR?

Tax evasion involves illegal means such as concealment or false statements. Tax avoidance uses arrangements that may be legal in form. GAAR targets avoidance that has a tax-driven main purpose and a tainted element, and allows the tax consequences to be redetermined.

Who has to prove the main purpose of the arrangement?

If the main purpose of a step or part of the arrangement is a tax benefit, section 179(2) presumes the whole arrangement has that purpose. The assessee must prove the contrary. So the burden of rebuttal lies on the assessee.
