Section 79 is the Income Tax Act's anti-abuse provision designed to prevent profitable companies from acquiring loss-making entities purely to use their tax losses. For founders raising funding, companies undergoing M&A, and businesses restructuring ownership, Section 79 can silently destroy years of accumulated losses with a single shareholding change. Understanding the 51% rule, the exceptions, and the depreciation safety net is essential for any corporate tax strategy.
For companies managing income tax return filing, Section 79 compliance directly impacts Schedule CFL and the tax audit report (Clause 32(b)).
The Core Rule: 51% Voting Power Continuity
Section 79 provides that for a closely held company (a company in which the public are NOT substantially interested), no loss incurred in any prior year shall be carried forward and set off against the income of the current year unless:
On the last day of the current previous year (the year in which set-off is claimed), the shares carrying not less than 51% of the voting power are beneficially held by the same persons who held shares carrying not less than 51% of the voting power on the last day of the year in which the loss was incurred.
| Element | Requirement |
|---|---|
| Applicable to | Closely held companies only (not listed, not substantially public-held) |
| Threshold | 51% of voting power must be held by same beneficial owners |
| Comparison dates | Last day of loss year vs last day of set-off year |
| What is restricted | Carry forward and set off of business losses, speculative losses, capital losses |
| What is NOT restricted | Unabsorbed depreciation (Section 32(2)) - can be carried forward regardless |
| Trigger | Change exceeding 49% of beneficial voting power |
Professional tax planning services can model the impact of proposed shareholding changes on existing loss carry forward before any transaction is executed.
Finance Bill 2025 Amendment: Continuous Holding
The Finance Bill 2025 introduced an important clarification to Section 79:
Amendment: The 51% shareholding continuity condition must be maintained at all times after the year in which the loss was incurred - not just on the last day of the set-off year.
Before amendment: Companies could potentially restructure shareholding temporarily (break the 51% continuity) and then restore it before the last day of the set-off year. The loss carry forward might survive because the "snapshot" test on the last day was satisfied.
After amendment: If 51% continuity is broken at any point between the loss year and the set-off year, the carry forward is permanently lost - even if the shareholding is restored before the comparison date. This is a stricter, continuous holding test.
Exceptions: When Section 79 Does NOT Apply
| Exception | Condition | Impact |
|---|---|---|
| Public companies | Company in which public are substantially interested (listed companies, widely held) | Section 79 does not apply at all. Losses can be carried forward regardless of shareholding changes. |
| Death of shareholder | Change in voting power occurs due to death of a shareholder | Does not trigger Section 79 restriction |
| Gift to relative | Change occurs due to gift of shares to a relative of the shareholder | Does not trigger Section 79 |
| Amalgamation/demerger of foreign holding company | 51% of foreign parent shareholders continue to hold shares in the resulting foreign company | Carry forward preserved |
| IBC resolution plan | Change in shareholding under Section 241/242 of Companies Act (NCLT-approved) | Carry forward preserved for the company and its subsidiaries |
| Eligible startups (DPIIT) | ALL shareholders continue to hold shares on last day of set-off year + loss within 10 years of incorporation | Carry forward preserved even without 51% continuity |
The Startup Exception (Section 80-IAC)
Recognising that startups frequently raise multiple funding rounds that dilute founder shareholding below 51%, the government carved out a special relaxation:
- Applicable to DPIIT-recognised eligible startups under Section 80-IAC
- Even if 51% continuity is broken, losses can be carried forward if ALL shareholders who held voting power in the loss year continue to hold shares in the set-off year
- The loss must have been incurred within 10 years of the company's incorporation (extended from 7 years by Budget 2025)
- This means new investors can join (diluting existing shareholders below 51%) without destroying loss carry forward - as long as no existing shareholder exits completely
- If an existing shareholder sells their entire holding - even a small percentage - the startup exception fails
For startup founders, refer to ITR for business for correct loss carry forward reporting with DPIIT certification.
Unabsorbed Depreciation: Immune from Section 79
Critical distinction: Section 79 restricts carry forward of losses - specifically business losses, speculative losses, and capital losses. It does NOT restrict carry forward of unabsorbed depreciation under Section 32(2).
This means: even if 51% shareholding changes completely and all business loss carry forward is destroyed under Section 79, the company's unabsorbed depreciation survives intact and can still be carried forward indefinitely. This is a crucial saving grace for many M&A transactions.
| Attribute | Business Loss | Unabsorbed Depreciation |
|---|---|---|
| Affected by Section 79? | Yes - carry forward lost if 51% changes | No - immune. Carries forward regardless. |
| Carry forward period | 8 years | Unlimited |
| Set off against | Business income only (when carried forward) | Any head except salary |
| Due date filing required | Yes | No |
For capital gains from M&A transactions, refer to ITR for capital gains for correct Schedule CG reporting.
Worked Examples
Example 1: Shareholding Change - Loss Destroyed
ABC Pvt Ltd - AY 2023-24: Business loss Rs 15 lakh. Shareholders: Mr. A (60%), Mr. B (40%). AY 2025-26: Mr. A sells entire 60% to Mr. C. New holding: Mr. C (60%), Mr. B (40%).
Section 79 test: On last day of AY 2023-24: A(60%)+B(40%). On last day of AY 2025-26: C(60%)+B(40%). Same persons holding 51%? Mr. B holds 40% (same). Mr. A no longer holds. Total continuity: 40% < 51%. Condition FAILS.
Result: Rs 15 lakh business loss carry forward destroyed. Cannot be set off in AY 2025-26 or any future year. However, if ABC had unabsorbed depreciation of Rs 5 lakh - that survives and can still be carried forward.
Example 2: Startup Funding Round - Loss Preserved
XYZ Startup Pvt Ltd (DPIIT-recognised, incorporated 2020) - AY 2023-24: Business loss Rs 20 lakh. Founders: P (70%), Q (30%). AY 2025-26: Series A investor R joins with 55% stake. New: P (31.5%), Q (13.5%), R (55%).
Standard 79 test: P+Q held 100% in loss year. Now hold 45% < 51%. FAILS.
Startup exception: P still holds shares. Q still holds shares. ALL original shareholders continue to hold (nobody exited). Loss within 10 years of incorporation. PASSES.
Result: Rs 20 lakh loss carry forward preserved. The startup exception saves it even though standard 51% test fails.
Example 3: Death Exception
MNO Pvt Ltd - Mr. M (55%), Mr. N (45%). Mr. M dies. Shares inherited by Mrs. M. New: Mrs. M (55%), Mr. N (45%).
Result: Change due to death - exception applies. Loss carry forward preserved. Section 79 not triggered.
Example 4: Continuous Holding Broken (Post-2025 Amendment)
DEF Pvt Ltd - AY 2023-24: Loss Rs 10 lakh. Shareholders: X (60%), Y (40%). In FY 2024-25, X sells 20% to Z. Holding: X (40%), Y (40%), Z (20%). Later in FY 2025-26, X buys back 20% from Z. Holding restored: X (60%), Y (40%).
Pre-amendment: On last day of FY 2025-26: X(60%)+Y(40%) = same as loss year. Test might pass.
Post-amendment: 51% continuity was broken during FY 2024-25 (X held only 40%). Even though restored later, the continuous holding test fails. Loss carry forward destroyed. Ensure TDS return filing and corporate compliance reflect the shareholding changes in each year's return.
Tax Audit Reporting: Clause 32(b)
The tax auditor must report under Clause 32(b) of the tax audit report (Form 3CD) whether any change in shareholding has occurred during the previous year that impacts carry forward of losses under Section 79. This includes disclosing the percentage of voting power held by each shareholder at the beginning and end of the year, and whether the 51% continuity test is satisfied.
Common Mistakes to Avoid
Mistake 1: Assuming Section 79 applies to public companies. Section 79 applies ONLY to closely held companies. Listed companies and companies where public holds substantial interest are exempt.
Mistake 2: Confusing business loss with depreciation. Section 79 destroys business loss carry forward but NOT unabsorbed depreciation. Many companies panic after shareholding changes without realising their depreciation is safe.
Mistake 3: Startup founder selling entire stake. The startup exception requires ALL original shareholders to continue holding. If even one founder sells their entire holding, the exception fails for all accumulated losses.
Mistake 4: Not considering beneficial ownership. Section 79 looks at "beneficial" holding, not just legal/registered ownership. Shares held through nominees may or may not satisfy the test depending on who the beneficial owner is.
Mistake 5: Ignoring the continuous holding amendment. Post Finance Bill 2025, the 51% test must be satisfied at ALL times after the loss year - not just on the last day. Temporary breaches are now fatal.
Key Takeaways
Section 79 restricts carry forward of losses (not depreciation) in closely held companies when 51% voting power continuity is broken between the loss year and the set-off year.
Unabsorbed depreciation is immune from Section 79. It can be carried forward indefinitely regardless of shareholding changes - making it the most resilient tax attribute in M&A.
Exceptions: death of shareholder, gift to relative, amalgamation/demerger of foreign parent, IBC resolution plan, and DPIIT-recognised startups (within 10 years, all shareholders continue).
Finance Bill 2025 tightened Section 79: the 51% continuity must be maintained at ALL times after the loss year (continuous test) - not just on the snapshot comparison date.
For startups raising multiple funding rounds: the exception requires every original shareholder to continue holding shares. New investors can join, but no original shareholder can exit completely.
