What Is an Infrastructure Investment Trust (InvIT)?

An Infrastructure Investment Trust, or InvIT, is a pooled investment vehicle regulated by the Securities and Exchange Board of India (SEBI) that owns large-scale infrastructure projects like toll roads, power transmission lines, and pipelines, then passes the revenue back to investors as regular distributions. The structure lets asset owners monetize completed projects and lets ordinary investors take a fractional stake in infrastructure they could never buy outright. It works much like a Real Estate Investment Trust, except the underlying assets are highways and electrical grids backed by long-term concession agreements rather than office buildings and malls.

How the Structure Works

An InvIT is legally set up as a trust under Indian law, with the sole mandate of investing in infrastructure. SEBI requires that at least 80% of the trust’s total asset value sit in completed, revenue-generating projects. The remaining 20% can go to under-construction projects, government securities, or approved debt and money market instruments. That heavy tilt toward operational assets is the point: it keeps cash flow predictable, because the revenue streams already exist.

The assets don’t sit directly inside the trust. Each project is typically housed in a Special Purpose Vehicle (SPV), a separate legal entity created for that asset. The InvIT holds equity in these SPVs and may also lend to them. Revenue flows up from the SPV to the trust, and the trust distributes it to unitholders. This layering isolates the financial risk of one project from another, so a problem with a single toll road doesn’t automatically drag down a power transmission line held in a different SPV.

Investors buy units in the InvIT that represent fractional ownership of the whole portfolio. Public InvITs have minimum subscription amounts as low as ₹10,000 to ₹15,000 during an initial offering. Private InvITs require ₹1 crore or more.

Who Runs It

SEBI mandates four distinct roles, each held by a separate party, so that no single entity controls the money, the assets, and the oversight all at once.

The sponsor is the infrastructure company that initiates the trust and transfers its completed projects in. The sponsor must retain at least 15% of the total units for a minimum of three years after listing, keeping their financial interests aligned with ordinary unitholders. The sponsor is held responsible for all acts, omissions, and representations related to the trust’s formation and initial asset transfers.1Securities and Exchange Board of India. Amendments to SEBI InvIT Regulations – Sponsor Holding Requirements

The trustee is an independent fiduciary who holds the InvIT’s assets on behalf of unitholders. The trustee’s job is pure oversight, with no role in investment decisions. The investment manager handles asset acquisitions, divestitures, capital structure, and financial reporting, with the goal of maximizing net distributable cash flow. The project manager is the operational arm, running day-to-day maintenance and revenue collection on the underlying infrastructure. The sponsor or its affiliate must serve as project manager for at least three years from listing.

The Three Types of InvITs

SEBI recognizes three categories, with different rules on who can invest and how often they get paid.

  • Public InvITs are open to all investors, with units listed on recognized stock exchanges. Minimum subscription starts at ₹10,000 to ₹15,000, at least 20 investors must participate, and distributions happen at least every six months.
  • Private listed InvITs are offered through private placement to institutional investors and corporate bodies, then listed on an exchange. Minimum subscription is ₹1 crore (or ₹25 crore depending on asset type), with between 5 and 1,000 investors and distributions at least annually.
  • Private unlisted InvITs are also privately placed, but units cannot be listed. Minimum subscription is ₹1 crore, with between 5 and 20 investors and distributions at least annually.

All three share the same 90% distribution requirement and the same governance structure. The real differences are liquidity and accessibility: public InvITs trade freely, while private unlisted InvITs lock investors into a much less liquid position.2Securities and Exchange Board of India. Frequently Asked Questions for Infrastructure Investment Trusts

Where the Returns Come From

InvITs earn revenue from the assets they hold. Toll roads collect user fees. Power transmission lines earn contractually guaranteed payments from utilities. Pipelines charge fixed usage fees. These income streams tend to be stable because they’re tied to essential services under long-term concession agreements, often lasting 20 to 30 years or more.

SEBI requires InvITs to distribute at least 90% of their Net Distributable Cash Flow (NDCF) to unitholders.2Securities and Exchange Board of India. Frequently Asked Questions for Infrastructure Investment Trusts For public InvITs, this happens at least twice a year; for private InvITs, at least annually. The distributions themselves are a composite: interest income from debt the InvIT extended to its SPVs, dividend income from the equity stake in those SPVs, and a return-of-capital component that represents repayment of your original investment rather than profit. Each piece carries a different tax treatment.

Leverage

Public and private listed InvITs can borrow up to 70% of the value of their assets.2Securities and Exchange Board of India. Frequently Asked Questions for Infrastructure Investment Trusts Private unlisted InvITs set their own limits through the trust deed. Leverage amplifies returns when things go well and magnifies losses when they don’t, so the 70% cap acts as a guardrail. Watch how close an InvIT operates to that ceiling, especially when interest rates are rising and refinancing gets expensive.

Tax Treatment

Indian Residents

For resident unitholders, the tax depends on which component of the distribution you’re looking at. Dividend income distributed by an InvIT from its SPVs is subject to 10% withholding under Section 194LBA of the Income Tax Act. Interest income passed through to unitholders is also taxable, with 10% withholding when your PAN is on file and 20% if it isn’t.

The return-of-capital portion carries no withholding obligation for residents, but it reduces your cost basis in the units. When you sell, your capital gain will be larger because the basis is lower. Hold units for more than three years and gains are taxed as long-term capital gains; shorter holdings are taxed at your slab rate.

US Investors

US-based investors face a more complicated picture because they’re dealing with a foreign trust generating fragmented income streams. Interest income from the InvIT’s debt investments in its SPVs is taxed as ordinary income at your marginal rate. Dividend income is generally taxed at ordinary rates as well. India may withhold tax at the source on both, and US investors can typically claim a credit for foreign taxes paid by filing IRS Form 1116.3Internal Revenue Service. Foreign Tax Credit

The return-of-capital component is not immediately taxable. Instead, it reduces your cost basis. You defer the tax until you sell, when you’ll recognize a larger capital gain because of the reduced basis. If cumulative return-of-capital distributions exceed your original cost, the excess becomes taxable as capital gains at that point.4Internal Revenue Service. Mutual Funds (Costs, Distributions, Etc.) – Return of Principal Payments

Two additional US filing regimes make ownership expensive to handle correctly. A foreign entity is generally a Passive Foreign Investment Company (PFIC) if more than 75% of its gross income is passive or more than 50% of its assets produce passive income. Many InvITs will meet this definition because their revenue is almost entirely passive investment income from SPV holdings. If classified as a PFIC, the default treatment under 26 U.S.C. § 1291 is punitive: any “excess distribution” is spread across every day you’ve held the units, the portion allocated to prior years is taxed at the highest marginal rate that applied in those years, and interest is charged on the resulting tax as though it were an underpayment dating back to each prior year.5Office of the Law Revision Counsel. 26 USC 1291 – Interest on Tax Deferral Gains on selling PFIC shares get the same treatment. Investors subject to PFIC rules file IRS Form 8621.6Internal Revenue Service. About Form 8621 – Information Return by a Shareholder of a Passive Foreign Investment Company

Separately, because an InvIT is legally a foreign trust, US investors who receive distributions may also need to file Form 3520 to report transactions with a foreign trust.7Internal Revenue Service. Foreign Trust Reporting Requirements and Tax Consequences That obligation is distinct from Form 8621 and reports the trust relationship itself. Penalties for missing either filing are steep, and professional preparation typically runs several hundred dollars per form.

Main Risks

Stable income is not guaranteed income, and several risks can erode returns or principal.

Interest Rate Sensitivity

Infrastructure assets with long, predictable cash flows behave somewhat like bonds. When rates rise, their relative attractiveness drops and market valuations tend to fall. InvITs operating near the 70% borrowing limit face a double hit, because refinancing costs climb at the same time unit prices are under pressure. Regulated utilities and toll roads are the most sensitive; higher-growth assets like data centers and power generation tend to be less affected because their revenue can grow with demand.

Currency Risk for Foreign Investors

Distributions are paid in Indian rupees. For a US investor, every payment and every unit sale must be converted back to dollars. If the rupee weakens during your holding period, your returns shrink even if the InvIT’s operations performed well. Hedging is available through forwards and options but expensive and impractical for most retail investors. Over long holding periods, currency movements can meaningfully change your total return in either direction.

Concession and Regulatory Risk

Many infrastructure assets operate under government concession agreements with defined expiration dates. When a concession ends, the SPV holding that asset may lose its revenue stream entirely. SEBI has proposed that investment managers must either exit the SPV or ensure it acquires a new infrastructure project within one year of concession expiry. Regulatory changes to toll rates, tariff structures, or environmental requirements can also affect profitability.

Concentration Risk

Some InvITs hold a small number of assets in a single sector. A trust that owns three toll roads in one region is heavily exposed to traffic patterns, local economic conditions, and regional regulatory decisions. Larger, diversified InvITs spanning multiple sectors and geographies distribute risk better, but even the biggest trusts remain concentrated compared to a broad equity index fund.

InvITs Compared to REITs

Both use the same pass-through trust structure and share the 90% distribution requirement. The differences come down to what’s inside and how long the cash flows last.

REITs hold commercial real estate: offices, malls, warehouses, hotels. Tenants sign leases that typically run 5 to 15 years, sometimes up to 30 for anchor tenants. Vacancy is a constant concern. InvITs hold infrastructure assets with concession agreements or long-term contracts that can stretch 20 to 60 years. A toll road concession lasting half a century gives visibility into future cash flows that a five-year office lease cannot match.

That longer duration cuts both ways. InvIT cash flows are more predictable, but the assets are less flexible. You can renovate an office building or change tenants; you can’t easily repurpose a highway. REITs are more sensitive to local real estate cycles, while InvITs are more sensitive to government regulation and interest rates. Both are regulated by SEBI in India, both trade on stock exchanges in their public forms, and both offer yields that tend to sit above government bonds.

How to Buy Units

Public InvIT units trade on Indian stock exchanges like the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE), just like ordinary stocks. If you have a brokerage account with access to Indian markets, you can buy and sell units throughout the trading day at market prices. For Indian residents, this is straightforward through any standard demat account.

Units can also be purchased during an initial public offering, where the InvIT first offers units at a fixed price or within a price band before secondary market trading begins. IPO subscriptions lock your capital until listing, but sometimes offer a slight discount to what the units eventually trade for on the open market.

US investors face an additional layer of friction. Most major US brokerages don’t offer direct access to Indian exchanges, so you’d typically need an international broker or a platform that supports Indian equities. Factor in currency conversion costs, the tax complexity above, and the need for specialized tax preparation when deciding whether the yield justifies the overhead. For smaller portfolios, compliance costs alone can eat a meaningful chunk of the income.
