The tax rule that quietly punishes startups for raising money
Almost every startup loses money for its first few years — that is the model. You spend to build, you burn to grow, and those early losses pile up as carried-forward losses that are supposed to shelter your profits later, once the business finally turns the corner. It is one of the few genuinely valuable assets on a young company's balance sheet. And there is a provision in the Income-tax Act that can silently destroy it: Section 79. It was written to stop people buying loss-making shell companies purely to use up their losses — a sensible anti-abuse rule. But it was written before the modern startup, and applied literally, it treats a founder raising a normal funding round exactly like a loss-trafficker. Every equity round a startup raises threatens to wipe out the losses it spent years accumulating. Here is how that trap works, and the specific relaxation that lets DPIIT-recognised startups walk through it.
The general rule — Section 79 and the 51% test
Section 79 applies to a company in which the public are not substantially interested — which is to say every closely-held private limited company, and therefore virtually every funded startup. For such a company, a loss from an earlier year can be carried forward and set off against a later year's profit only if there is continuity of ownership. Precisely: on the last day of the year in which you want to set off the loss, shares carrying at least 51% of the voting power must be beneficially held by the same persons who held them on the last day of the year in which the loss was originally incurred.
Break that 51%-continuity, and the brought-forward loss lapses — it cannot be set off at all. The logic is clean for its intended target: if a profitable business buys a dormant company only to inherit its accumulated losses, the ownership has changed by more than 51%, the test fails, and the losses are denied. No tax arbitrage. The problem is what the same test does to a legitimate startup.
Why this is a startup-specific problem
Think about how a startup's cap table actually moves. The founders own 100% at incorporation. Then comes an angel round, a seed round, a Series A — each one issues fresh equity to new investors, and each one dilutes the founders. By the time a startup has raised a couple of rounds, the original shareholders often hold well under 51% between them. Under the plain 51% test, that startup has broken ownership continuity — not because anyone trafficked in losses, but because it did exactly what a startup is supposed to do: raise capital.
The result, without relief, is perverse: a startup accumulates losses in its early years, raises money to survive and grow, and in doing so forfeits the very losses that were meant to reduce its tax bill once it becomes profitable. The rule designed to catch abuse ends up penalising the healthiest thing a young company can do. This is exactly the gap the law was amended to close for recognised startups.
The relaxation for eligible startups
Section 79 carries a specific carve-out for an eligible start-up as referred to in Section 80-IAC — that is, a DPIIT-recognised startup that qualifies for the Section 80-IAC tax holiday. For such a startup, the loss is not denied merely because the 51% test fails. Instead, the loss can still be carried forward and set off provided a different, more forgiving condition is met:
- All the shareholders who held shares carrying voting power in the year the loss was incurred continue to hold their shares on the last day of the year in which the loss is set off; and
- the loss was incurred during the period of ten years beginning from the year in which the company was incorporated.
The shift is subtle but decisive. The ordinary test asks whether 51% of the ownership stayed constant. The startup test asks only whether the original people stayed in. New investors can come in, the founders can be diluted far below 51%, the cap table can be transformed — and the losses survive, as long as the shareholders who were there in the loss year have not exited. In practice this means that as long as the founding shareholders remain on the register (they need not retain a controlling stake), the startup keeps the full benefit of its carried-forward losses through round after round of dilution.
The ten-year window is not accidental. It was extended from the original seven years to ten years precisely to line up with the ten-year window in Section 80-IAC within which a startup can claim its tax holiday — so the loss-protection period and the profit-exemption period now cover the same stretch of a startup's life.
How this fits with the Section 80-IAC tax holiday
These two provisions are two halves of the same startup tax architecture, and they are best understood together. Section 80-IAC handles the profit side: it lets an eligible startup claim a 100% deduction of its profits for any three consecutive years out of its first ten. Section 79's relaxation handles the loss side: it makes sure the losses of the early, cash-burning years are not destroyed by the funding rounds, so they are still available to shelter profits later. One protects your losses on the way up; the other exempts your profits once you arrive. A startup that plans both together — rather than discovering Section 79 the hard way during a Series B due diligence — keeps far more of its early tax shield intact.
What you actually have to do to keep the losses
The relaxation is not automatic paperwork you file; it is a set of facts you have to preserve. Three things matter in practice:
- Be a genuinely eligible, DPIIT-recognised startup. The carve-out only applies to an eligible start-up under Section 80-IAC. If you have not secured DPIIT recognition, you do not get this relief — you are back on the ordinary 51% test.
- Keep your founding shareholders on the cap table. The whole relaxation turns on the original loss-year shareholders continuing to hold their shares. A founder fully exiting in a secondary sale can jeopardise the losses attributable to the years they were a shareholder, so founder exits and buy-backs should be planned with this in mind — this is one more reason the term sheet and shareholders' agreement matter for tax, not just control.
- Track your losses year by year. Because the test operates loss-year by loss-year, you need clean records of who held shares in each year a loss arose. This is where the way you paper your funding rounds — and who is a shareholder versus a convertible-instrument holder at year-end — feeds directly into whether a given year's loss is protected.
Where this sits in the startup journey
Section 79 is the tax rule that sits underneath every round on your Startup India journey. It is the reason DPIIT recognition is worth more than the badge: recognition is what unlocks both the 80-IAC tax holiday on your profits and this protection for your losses. It works hand in hand with the abolition of angel tax, which removed the other big tax risk that used to sit on a startup's fundraising, and it is shaped by how you structure your convertible instruments and equity rounds. Together they are the tax scaffolding of a well-run raise.

Verification note: The rules described here are based on Section 79 of the Income-tax Act, 1961, which restricts the carry forward and set off of losses of a company in which the public are not substantially interested unless shares carrying not less than fifty-one per cent of the voting power are beneficially held on the last day of the previous year of set-off by persons who beneficially held them on the last day of the year in which the loss was incurred, read with the relaxation for an eligible start-up as referred to in Section 80-IAC — under which the loss is not so denied if all the shareholders who held shares carrying voting power on the last day of the year in which the loss was incurred continue to hold those shares on the last day of the previous year in which the loss is set off, and the loss was incurred during the period of ten years beginning from the year of incorporation. The period was extended from seven to ten years by the Finance Act, 2023 (with effect from assessment year 2024-25) to align with the ten-year period in sub-section (2) of Section 80-IAC. Eligibility as a start-up requires recognition by the Department for Promotion of Industry and Internal Trade (DPIIT) and satisfaction of the conditions in Section 80-IAC. Provisions, time limits and eligibility conditions are periodically amended; confirm the current position for your company with your CA before relying on it for a transaction.
