In simple words (if you are in class 10)

Imagine your colony wants a big swimming pool. No single family can afford it. So 1,000 families each put in a small amount, a trusted person keeps the money safe, a manager runs the pool, and every month the ticket money (after paying the lifeguard and cleaning costs) is shared back with the families.

An InvIT (Infrastructure Investment Trust) works the same way, but the "pool" is a highway, a power transmission line, a gas pipeline or a telecom tower network.

  • Many people put money in and get units (like small shares).
  • The money is used to own finished infrastructure that already earns money, such as a toll road where vehicles already pay toll every day.
  • Most of the cash that is left after costs and loan payments must be paid out to unitholders regularly.
  • Units of listed InvITs trade on the stock exchange, so you can buy or sell them like shares.

One big difference from the swimming pool: a toll road is usually given to the owner only for a fixed number of years (the concession). When the period ends, the road goes back to the government. So part of what you receive every year is really your own money coming back, not just profit. We explain this in Part 7 on valuation.

How an InvIT is structuredCash flows up from the SPVs as interest, dividends and loan repayments, and goes to unitholders as distributions.

An InvIT is a trust registered under the Indian Trusts Act, 1882, and registered with SEBI under the SEBI (Infrastructure Investment Trusts) Regulations, 2014 (the "InvIT Regulations", originally notified in the Gazette of 26 September 2014). Operational detail sits in SEBI's Master Circular for InvITs, the most recent consolidated version being SEBI/HO/DDHS-PoD-2/P/CIR/2025/102 dated 11 July 2025, as amended from time to time.

For income-tax purposes an InvIT is a business trust, which is what gives it the "pass-through" treatment discussed in Part 4 on tax.

The parties

Party Role Plain-English analogy
Sponsor Sets up the InvIT and transfers (or arranges) the initial assets; must hold a minimum number of units for set periods The family that had the idea and put in the first, biggest share
Trustee A SEBI-registered debenture trustee that holds the assets in trust for unitholders and oversees the manager The trusted elder who keeps the locker key
Investment manager Takes investment decisions, runs the InvIT's affairs, makes disclosures, declares distributions The pool manager
Project manager Runs the actual assets day to day (toll collection, maintenance, O&M contracts) The lifeguard and cleaning staff contractor
Valuer Independent registered valuer who values the assets periodically The independent surveyor
Unitholders Investors who own units and vote on key matters The 1,000 families

The InvIT usually owns road SPVs (special purpose vehicles, i.e. companies that hold each concession). It funds them partly with equity and partly with shareholder loans. When the SPV pays the InvIT, the cash can arrive as interest, dividend or repayment of the shareholder loan. Each of these is taxed differently in the investor's hands, which is why your distribution statement shows several components.

Under the InvIT Regulations, the InvIT must hold a controlling interest in each SPV. A rating agency summary of the rules describes this as at least 51% of SPV equity (or, through a HoldCo, an ultimate holding of at least 26%) plus the right to appoint a majority of the SPV board (CARE Ratings InvIT methodology, Dec 2022).

Public vs private InvITs

  • Public InvIT: units offered to the public and listed. Must keep at least 80% of asset value in completed, revenue-generating projects, and may put a limited share (up to 10%) into under-construction projects (Vinod Kothari summary of the InvIT Regulations, Feb 2026).
  • Private InvIT: units placed privately with institutional and other eligible investors; may be listed or unlisted. Rules on asset mix and minimum investment differ. In September 2025 SEBI's Board approved a lower minimum allotment lot of ₹25 lakh for privately placed InvITs (Indian Infrastructure, 15 Sep 2025).

Why governments and developers like InvITs

  1. Asset recycling. A developer or a public authority sells finished, cash-earning roads to an InvIT, gets cash upfront, and uses it to build new roads. This is the logic of the government's asset monetisation programme.
  2. Long-term, patient capital. Pension funds, insurers and sovereign funds want steady, long-dated cash flows. Operating toll roads and annuity roads match that need.
  3. Lower cost of capital once construction risk is gone, because the asset now carries operating risk only.

Public sector example: the National Highways Authority of India (NHAI) sponsors InvITs to monetise operational highways, and in December 2025 SEBI approved a second NHAI-sponsored InvIT, the Raajmarg Infra Investment Trust, aimed at retail and domestic investors (Business Standard, 24 Dec 2025). ICRA reports that NHAI raised ₹92,633 crore through TOT and InvITs together up to FY2025 (ICRA, Sep 2025).

What an InvIT is not

  • It is not a mutual fund. A mutual fund holds many traded securities; an InvIT owns and operates a few large physical assets through SPVs.
  • It is not a fixed deposit or bond. Distributions are not guaranteed. They depend on traffic, tariffs, costs, debt and regulation.
  • It is not a company, although it behaves like one in many ways. See Part 2: Why an InvIT and not a company?

Key takeaways

  • An InvIT is a SEBI-regulated trust that owns infrastructure through SPVs and passes most of its cash to unitholders.
  • Four key roles: sponsor, trustee, investment manager, project manager.
  • For a toll road InvIT, distributions are a mix of profit and return of your capital, because concessions end.
