What Is an InvIT? Infrastructure Investment Trusts in India Explained

Ask most investors what is InvIT and you will hear "a mutual fund for roads". That is close, but it misses what makes the product work.

An infrastructure investment trust is a trust registered with SEBI that raises money from unitholders and uses it to own infrastructure companies, usually through special purpose vehicles (SPVs) that hold a concession, a licence or a long-term contract. The SPV collects tolls, transmission charges, tower rentals or pipeline tariffs. After paying operating costs, interest and tax, it sends cash up to the trust, and the trust sends at least 90% of its net distributable cash flow to you.

So when you buy InvIT units you are not buying a construction company. You are buying a slice of finished, cash-generating assets in a trust that must pay most of its cash out.

Three features set an InvIT in India apart from a listed company:

• A payout rule. At least 90% of net distributable cash flow (NDCF) must be distributed, at least every six months for public InvITs.
• A leverage ceiling. Net borrowing across the trust and its SPVs cannot cross 70% of asset value.
• A tax pass-through. Interest and dividend received from SPVs are not taxed in the trust; they are taxed (or exempted) in the unitholder's hands.

Its sibling, the REIT, applies the same trust model to rent-yielding offices and malls; this guide sticks to InvITs.

The infrastructure investment trust was designed to recycle capital: developers and government agencies had money locked in completed roads and power lines, while pension funds and savers wanted long-dated income assets.

The milestones, in order:

• 7 October 2013: the Ministry of Finance notified the list of infrastructure sub-sectors that the regulations would later rely on.
• 26 September 2014: SEBI notified the Infrastructure Investment Trusts Regulations, 2014.
• Union Budget 2016-17: dividend distribution tax on SPV payouts to business trusts was withdrawn, removing a layer of tax.
• 28 November 2016: IndiGrid was registered with SEBI, and the first InvIT listings followed in 2017.
• 22 April 2019: the borrowing ceiling rose from 49% to 70% of asset value, and a separate chapter for privately placed unlisted InvITs was added.
• 30 July 2021: the minimum application in a public InvIT issue fell to Rs 10,000–15,000 (from Rs 1 lakh, itself cut from Rs 10 lakh), with a one-unit trading lot.
• Finance Act 2023: distributions labelled "repayment of debt", which had escaped tax, were brought into a formula-based tax.
• 3 September 2025: the private InvIT minimum was unified at Rs 25 lakh, down from Rs 1 crore or Rs 25 crore.
• 1 April 2026: the Income-tax Act, 2025 replaced the 1961 Act, and business trust taxation moved to section 223.
• 17 April and 16 October 2026: two amendments to the SEBI InvIT regulations took effect.
• 17 August 2026: the Taxation and Other Laws (Amendment) Act, 2026 received assent, changing InvIT taxation of dividends from 1 April 2026.

The market has grown alongside the rules. SEBI's register of InvITs listed 27 InvITs as of 25 October 2026, and the Bharat InvITs Association reported InvIT assets under management of Rs 7.1 lakh crore at the end of FY26, up from Rs 6.3 lakh crore a year earlier.

Every infrastructure investment trust has four parties with defined legal duties.

The sponsor sets up the trust and transfers the assets into it, usually a developer, a power utility or an infrastructure fund. SEBI requires each sponsor to have a net worth of at least Rs 100 crore (or net tangible assets of that size for an LLP) and a track record in infrastructure development or fund management.

The sponsor must keep skin in the game. Sponsors together must hold at least 15% of units for three years after listing. After that, the SEBI InvIT regulations keep a smaller tail: at least 5% in years four and five, 3% in years six to ten, and 2% in years eleven to twenty.

The investment manager runs the trust: it decides acquisitions and disposals, raises debt, computes NDCF and declares each InvIT distribution. If a distribution is paid late, the manager must pay unitholders 15% a year interest, and it cannot recover that from the trust as fees.

The trustee, which must be a SEBI-registered debenture trustee and cannot be an associate of the sponsor or manager, holds the assets in trust for unitholders. It oversees the manager, checks that related-party deals and borrowings follow the rules, and ensures the manager holds a unitholder meeting at least once a year.

The project manager operates the assets as the concession or project agreement requires, and supervises completion of any under-construction project.

Behind these four sit the SPVs (and sometimes holdcos). The SPV owns the concession; the trust owns the SPV. Cash moves up as interest on the trust's loans to the SPV, as dividends on its equity, and as repayment of those loans. That split decides your tax.

The names on SEBI's register tell you the asset mix:

• Roads and highways: toll roads and annuity roads under concessions from NHAI or state authorities. Trusts such as National Highways Infra Trust, IRB InvIT Fund, Cube Highways Trust and Anantam Highways Trust sit here. Toll income depends on traffic and on inflation-linked toll revisions; annuity roads are paid fixed sums by the authority.
• Power transmission: IndiGrid and the POWERGRID InvIT own inter-state transmission lines and substations that earn availability-based tariffs. Payment depends on keeping the line available, not on how much power flows.
• Renewable energy: trusts such as Sustainable Energy Infra Trust hold generation assets that sell power under long-term purchase agreements.
• Telecom towers and fibre: Altius Telecom Infrastructure Trust holds towers; Digital Fibre Infrastructure Trust holds fibre. Revenue comes from long-term tenancy contracts.
• Gas pipelines: Energy Infrastructure Trust holds a natural gas pipeline with capacity-based revenue.
• Warehousing and logistics: Intelligent Supply Chain Infrastructure Trust holds supply-chain assets.

The revenue model matters more than the sector label. A transmission line with an availability tariff behaves like a long bond with operating risk; a toll road behaves like a business tied to traffic. Both sit inside the same InvIT in India wrapper, but they do not carry the same risk.

The word "InvIT" covers three products. Most guides mention two; the SEBI InvIT regulations recognise three.

A public InvIT is the one a retail investor meets. It comes through an IPO, must list within twelve working days of the issue closing, and its InvIT units trade singly. No non-sponsor investor may take more than 25% of the unit capital in the initial offer. With at least 80% of assets in completed, revenue-generating projects, a public InvIT carries less development risk.

A private InvIT raises money from a select group, must list within thirty working days of allotment, and trades in Rs 25 lakh lots. Until 3 September 2025 the ticket was Rs 1 crore, or Rs 25 crore for mostly completed assets; SEBI unified it at Rs 25 lakh to match the trading lot. A private InvIT may hold more under-construction projects, so it suits institutions and large HNIs.

Since 2019 the rules have also allowed a private InvIT that never lists. It needs at least five unitholders outside the sponsor group holding a quarter of the units, and borrowing follows the trust deed rather than the 70% rule. These suit pension funds, sovereign funds and strategic investors.

The SEBI InvIT regulations, last amended with effect from 16 October 2026, contain far more than the minimum ticket. Four sets of rules matter.

All investment must be in Indian infrastructure, through holdcos, SPVs or direct projects. A public InvIT must keep at least 80% of asset value in completed, revenue-generating projects; the remaining 20% may go to under-construction projects (capped at 10%), listed infrastructure debt, shares of infrastructure companies, government securities and similar instruments. An InvIT may not invest in units of another InvIT. In public-private partnership (PPP) projects, the trust must invest through a holdco or SPV rather than owning the project directly.

Net borrowings of the trust, holdcos and SPVs together, after cash, cannot exceed 70% of the value of InvIT assets. Beyond 25%, every further loan needs a credit rating and unitholder approval. Beyond 49%, the trust needs a AAA issuer rating and a special resolution in which at least 75% of votes cast are in favour. SEBI circulars in 2026 also set how highly leveraged trusts may use fresh borrowing.

An independent valuer carries out a full valuation, with physical inspection of every project, at least once a financial year; publicly offered InvITs also need a half-yearly valuation as at 30 September. The trust publishes quarterly results, NDCF statements and its net borrowing ratio.

Major decisions need unitholder approval: large acquisitions, related-party deals, a change of sponsor or manager, and delisting. The Second Amendment, effective 16 October 2026, rewrote several thresholds as "at least 75% of total votes cast" instead of 75% of unitholders by value. It also allowed depository receipts on InvIT units and an exit option when one sponsor leaves a multi-sponsor InvIT.

NDCF drives every InvIT distribution. SEBI's July 2025 master circular for InvITs builds it from the cash-flow statement: operating cash flow, plus asset-sale proceeds not reinvested, minus debt repayments and lender reserves, first at each SPV or holdco and then at the trust.

The two-stage rule is:

1. Each SPV must pass at least 90% of its NDCF to the trust (or holdco), in proportion to the trust's holding.
2. The trust must pass at least 90% of its own NDCF to unitholders.

A public InvIT must declare distributions at least once every six months, and a private InvIT at least once a year. Payment must reach you within five working days of the record date, which falls two working days after declaration.

One rule protects you from flattering payouts: a trust cannot fund an InvIT distribution by raising external debt. The August 2026 SEBI circular on NDCF made a narrow exception, allowing road InvITs to add back major-maintenance spending financed by outside borrowing, but only with unitholder approval for each project, an auditor's certificate and separate disclosure.

Take a hypothetical public InvIT with 100 crore units issued at Rs 100.

• Trust-level NDCF for the half-year: Rs 500 crore.
• Minimum it must distribute (90%): Rs 450 crore.
• It declares Rs 480 crore, or Rs 4.80 per unit.

The manager labels that Rs 4.80 by source:

• Interest from SPVs: Rs 3.00
• Dividend from SPVs: Rs 0.50
• Repayment of SPV loans: Rs 1.30

If you hold 1,000 InvIT units, you receive Rs 4,800: Rs 3,000 of interest, Rs 500 of dividend and Rs 1,300 of repayment of debt. Annualised, that is about 9.6% on the issue price, but what you keep depends on the split.

InvIT taxation follows one idea: the infrastructure investment trust is a pass-through for income from SPVs, so each component keeps its character in your hands. Section numbers below are from the Income-tax Act, 2025, which applies from 1 April 2026; the old 1961 numbers are in brackets.

Interest is often the largest slice, because many trusts fund their SPVs largely through loans. Under section 223, it is taxed as your income at your slab rate. The trust deducts 10% TDS for residents under section 393(1) and 5% for non-resident unitholders under section 393(2), Table Sl. 6. For someone in the 30% slab, Rs 3,000 of interest in our example costs about Rs 936 in tax including 4% cess (before any surcharge), of which Rs 300 is already deducted.

Dividends are where InvIT taxation changed this year. Under Schedule V as first enacted, a unitholder lost the dividend exemption if the SPV had opted for the concessional corporate tax regime under section 200.

The Taxation and Other Laws (Amendment) Act, 2026, which received assent on 17 August 2026 and applies from 1 April 2026, omitted that condition. Dividends passed through by a business trust are now exempt for unitholders, a relief first reported when the Bill was tabled, whether or not the SPV uses the concessional regime. The trade-off sits at the SPV: the surcharge for qualifying SPVs of business trusts under sections 200 and 201 rose from 10% to 25%, so some tax moves upstream and can reduce the cash available for distribution.

One practical gap remains. The withholding rules that waive TDS on SPV dividends still refer to SPVs that have not chosen section 200, so how trusts apply TDS on dividends from section 200 SPVs is a matter to check in your statement. Non-residents face 10% TDS on the dividend component under section 393(2).

When an SPV repays its loan from the trust, the trust passes that cash on as "repayment of debt". It is not taxed when you receive it. Instead:

• It reduces the cost of acquisition of your units (section 72), so you pay more capital gains tax when you sell.
• Once the total of such sums received on a unit, across all years and all previous holders, exceeds the unit's issue price, the excess becomes taxable as income from other sources under section 92(2)(k), less any amount already taxed.

In our example, the Rs 1,300 of repayment lowers your cost from Rs 1,00,000 to Rs 98,700. Nothing is taxed this year, and nothing will be taxed as income until cumulative repayments pass Rs 100 a unit.

Listed InvIT units sold on an exchange, with securities transaction tax paid on the sale, are taxed like listed shares. Units held more than 12 months give long-term gains taxed at 12.5% above Rs 1.25 lakh a year under section 198; units held 12 months or less give short-term gains taxed at 20% under section 196. Unlisted units follow the general capital-gains rules.

Each year the trust gives you a statement splitting payouts by component; under the old rules it was Form 64B. Use it, not the bank credit, to fill your return. Because InvIT taxation changed in 2026 and has grey areas, confirm your position with a tax adviser before filing.

Public InvIT units settle in demat form and trade on NSE and BSE like shares, with prices visible on the NSE REITs and InvITs market page, so you can buy a single unit through a broking app, and distributions and disclosures arrive through exchange filings.

The asset mix is also digital: SEBI's register includes trusts for telecom towers, optical fibre and supply-chain infrastructure. The October 2026 amendment allowing depository receipts on InvIT units creates a legal path for offshore investors, once SEBI specifies the mechanics.

For mutual funds and specialised investment funds, InvITs remain hybrid instruments even though REITs became equity on 1 January 2026. Fund-raising continues at pace: between April and September 2026, eight InvIT issues raised Rs 7,315.32 crore, all from listed trusts, according to SEBI's fund-raising data for REITs and InvITs.

The case rests on rules, not marketing.

• Mandated cash flow. The 90% NDCF rule and the half-yearly minimum mean income is a legal obligation, not a board's discretion, as long as the cash exists.
• Low entry for a public InvIT. Rs 10,000–15,000 at issue, or one unit on the exchange, opens assets once held only by developers and pension funds.
• Operating assets, not construction risk. Public InvITs must keep 80% in completed, revenue-generating projects.
• Capped leverage with gates. The 70% ceiling, AAA requirement above 49% and unitholder votes limit balance-sheet risk.
• Tax efficiency on part of the payout. The dividend component is exempt and repayment of debt is deferred until sale or until cumulative sums exceed the issue price.
• Liquidity and price discovery. Listed units can be sold on any trading day, unlike a direct stake in an infrastructure project.

For someone who wants long-duration cash flow beside an equity portfolio, an infrastructure investment trust simplifies the job: a payout schedule, a standard NDCF statement and an annual tax breakdown.

Here is how to invest in InvIT units in practice, through a public InvIT or a private InvIT.

1. Use a demat and trading account. Public InvIT units are held in demat form and bought through a stockbroker.
2. Pick the route. Buy a public InvIT on NSE or BSE in one-unit lots, or apply in an IPO with Rs 10,000–15,000. A private InvIT needs Rs 25 lakh, through the placement or a Rs 25 lakh trading lot.
3. Read the asset base. Check concession end dates, the counterparty and whether revenue is toll-based or availability-based.
4. Read the latest NDCF statement. Compare distributions with NDCF and check the interest, dividend and repayment split.
5. Check leverage and rating against the 49% and 70% markers.
6. Estimate post-tax yield. Apply your slab rate to the interest part; treat repayment of debt as return of your own capital.
7. Size the position as part of your income allocation, not as a fixed deposit replacement.

Non-residents can invest in units of SEBI-registered investment vehicles under FEMA's non-debt instrument rules, but the account route and repatriation terms should be confirmed with your bank before buying.

Start with what PMS Sahi Hai does not do. It does not list, rate or sell InvITs, and Nyra does not score them. What the platform does is help you see the rest of the portfolio that an InvIT has to sit beside, which is where most income decisions actually go wrong.

An InvIT is rarely a whole portfolio. It is an income layer next to equity, debt and, for larger investors, PMS strategies or AIFs. The useful questions are about the mix: how much growth capital stays in equity, how much income you want from trusts, and whether a private-credit or infrastructure AIF would duplicate the same exposure at a higher ticket. PMS Sahi Hai is built for that comparison.

• Compare the growth side. The compare page puts PMS, AIF and GIFT City strategies side by side, so the equity allocation you hold next to InvIT units is chosen on data, not on a pitch.
• Check the AIF alternative. If you are weighing an InvIT against a Category II fund, the AIF comparison page shows category, strategy, lock-in and returns. The contrast is stark: InvIT units trade daily, while AIF units are locked in, as the guide on how AIFs work in India explains.
• Compare the tax wrappers. Both business trusts and Category I and II AIFs are pass-through vehicles, but the rules differ. The insight on whether an AIF is tax free is a useful counterpoint to the InvIT tax table above.
• Ask Nyra. Nyra, the platform's AI research tool, answers questions about PMS and AIF strategies in plain English. Its methodology scores PMS and AIF strategies on five weighted pillars and marks anything with under 12 months of track record as "Not Rated".

For the allocation question itself, the insight on asset allocation strategies for PMS investors walks through how managers balance equity, debt, gold and alternatives. Nyra describes itself as an analytical tool, not a SEBI-registered investment adviser, so treat its output as research, not advice.

InvIT risks are real, and some are structural to how an infrastructure investment trust works.

• Distributions are not guaranteed. Traffic can fall, tariffs can be revised, and a line can be unavailable. The 90% rule applies to cash that exists; it cannot create cash.
• Assets hand back. Road concessions end and the asset returns to the authority. Part of many payouts is your own capital coming back, which is why repayment of debt reduces your cost base. A high headline yield can hide a shrinking asset.
• Interest-rate sensitivity. Unit prices can fall when bond yields rise, and with leverage up to 70% of asset value, refinancing costs feed into NDCF.
• Tax drag. The interest component is taxed at your slab rate, so a 30% taxpayer keeps much less than the headline figure. The SPV-level surcharge increase from 2026 also reduces cash at source for some trusts.
• Sponsor conflicts. Sponsors sell assets into the trust and may stay involved in operating them. Related-party votes are excluded, but valuations deserve scrutiny.
• Liquidity varies. Some units trade thinly, and private InvIT lots are Rs 25 lakh.
• Regulatory and tax change. Rules on NDCF, voting and dividend tax all changed in 2025–2026; more change is likely.

An infrastructure investment trust suits an investor who wants regular, asset-backed cash flow, accepts that the unit price will move, and is willing to read an NDCF statement and a tax breakdown. It suits a long horizon, because concession assets reward patience and punish trading on yield alone. If the InvIT is one part of a larger plan, PMS Sahi Hai and Nyra can help you compare the PMS and AIF pieces around it.

It does not suit someone who needs a guaranteed return. The deciding questions are: what the trust owns, how long the concessions run, how much of each InvIT distribution is interest versus repayment of debt, how leveraged it is, and what you keep after tax.

An InvIT can be a useful income building block, but only once you have read the structure, the payout mix and the tax. Write down what you need the money to do, compare each InvIT distribution with the other income options you already hold, and check the post-tax figure before committing.

Then look at the whole portfolio. Use PMS Sahi Hai's compare page to line up the PMS and AIF strategies around your InvIT units, ask Nyra to explain a strategy or a score, and book a conversation with the team if you want a second view. Treat this guide as information, not a recommendation, and speak to a tax professional before you invest.
