An Infrastructure Investment Trust, known as an InvIT, is a pooled investment vehicle regulated by the Securities and Exchange Board of India (SEBI) that owns completed, revenue-generating infrastructure assets like toll roads, power transmission lines, and pipelines, and passes most of the cash they produce back to investors as regular distributions. It works much like a Real Estate Investment Trust, but the underlying assets are pieces of national infrastructure rather than office buildings or malls. For an ordinary investor, an InvIT is a way to hold a fractional stake in projects that would otherwise be out of reach, and to receive income backed by long-term concession agreements.
How the Structure Works
An InvIT is legally set up as a trust under Indian law with a single mandate: invest in infrastructure. SEBI regulations require that at least 80% of the trust’s total asset value sit in completed, revenue-generating projects. The remaining 20% can go into under-construction projects, government securities, or approved debt and money market instruments. That heavy tilt toward operating assets is deliberate. It keeps cash flow predictable because the revenue streams already exist.
The assets themselves 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 layered arrangement isolates the risks of one project from another, so trouble at a single toll road doesn’t automatically drag down a transmission line held in a different SPV.
Investors buy units in the InvIT, and each unit represents fractional ownership of the entire 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 an InvIT
SEBI requires four separate parties, so no single entity controls the money, the assets, and the oversight at the same time.
The sponsor is the infrastructure company that sets up the trust and transfers its completed projects into it. The sponsor must hold at least 15% of the total units for a minimum of three years after listing, keeping their interests aligned with ordinary unitholders. The sponsor also carries responsibility for the acts, omissions, and representations tied 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 assets on behalf of unitholders and makes sure the trust operates within SEBI rules. The trustee has no say in investment decisions.
The investment manager handles all financial and investment decisions: acquisitions, divestitures, capital structure, and reporting. Their job is to maximize the net distributable cash flow that ultimately reaches investors.
The project manager is the operational arm, responsible for physical maintenance and revenue collection at each asset. The sponsor or its affiliate must serve as project manager for at least the first three years after listing.
Types of InvITs
SEBI recognizes three categories, and the differences mostly come down to who can invest and how easily units can be sold.
Public InvITs are open to all classes of investors, with units listed on recognized stock exchanges. Minimum subscription starts at ₹10,000 to ₹15,000, and at least 20 investors must participate. Distributions happen at least every six months.
Private listed InvITs are placed with 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 once a year.
Private unlisted InvITs are also privately placed but never listed on any exchange. Minimum subscription is ₹1 crore, between 5 and 20 investors, and distributions at least once a year.
All three share the same 90% distribution requirement and the same governance structure.2Securities and Exchange Board of India. Frequently Asked Questions for Infrastructure Investment Trusts The practical difference for most investors is liquidity: public units trade freely, private unlisted units do not.
How Investors Get Paid
InvITs earn revenue from the assets they hold. Toll roads collect user fees. Power transmission lines earn contracted payments from utilities. Pipelines charge usage fees. These income streams tend to be stable because they’re tied to essential services under long-term concessions that can run 20 to 30 years or longer.
SEBI requires that at least 90% of Net Distributable Cash Flow (NDCF) be paid out to unitholders.2Securities and Exchange Board of India. Frequently Asked Questions for Infrastructure Investment Trusts That high threshold forces most of the income through to investors instead of letting it sit in the trust. For public InvITs the payout happens at least twice a year, for private InvITs at least once.
The distributions are a mix of income types, and the mix matters for tax. A typical payout combines interest income from debt the InvIT extended to its SPVs, dividend income from the equity stake in those SPVs, and a return-of-capital portion that represents a repayment of the investor’s original investment rather than profit. Income passes through in the form it was earned, which is how the trust avoids being taxed at the entity level. Tax lands on the investor.
Borrowing and 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 in the trust deed. Leverage boosts returns when conditions are good and worsens losses when they aren’t, so the 70% ceiling is a guardrail. It’s worth watching how close an InvIT sits to that cap, especially when interest rates are climbing and refinancing gets expensive.
Tax Treatment for Indian Residents
For Indian resident unitholders, tax depends on which component of the payout you’re looking at. Dividend income distributed by the 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 the investor’s PAN is on file and 20% when it isn’t.
The return-of-capital portion isn’t treated as income and isn’t subject to withholding for resident unitholders. It does reduce your cost basis in the units, which means a larger capital gain when you eventually sell. Hold units more than three years and gains are taxed as long-term capital gains; shorter holdings are taxed at the applicable slab rate.
Tax Treatment for US Investors
US-based investors face a more complicated picture because they’re dealing with a foreign trust that generates three separate income streams, each taxed differently.
Interest income from the InvIT’s SPV debt is taxed as ordinary income at your marginal rate. India may withhold at the source, and US investors can usually claim a credit for foreign taxes paid by filing IRS Form 1116.3Internal Revenue Service. Foreign Tax Credit Dividend income is generally also taxed at your ordinary rate, with a similar foreign tax credit potentially available.
Return-of-capital distributions are not immediately taxable. They reduce your cost basis in the units, and tax is deferred until you sell, at which point the gain is larger because of the lower basis. If cumulative return-of-capital distributions exceed your original cost, the excess is taxed as capital gains from that point on.4Internal Revenue Service.

PFIC Classification
US investors also need to consider whether the InvIT is a Passive Foreign Investment Company (PFIC) under US tax law. A foreign entity generally falls into PFIC territory if more than 75% of its gross income is passive, or if more than 50% of its assets produce passive income. Many InvITs meet that definition because their revenue is almost entirely passive investment income from SPV holdings.
PFIC status matters because the default tax treatment is punitive. Under 26 U.S.C. § 1291, 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 each of those years, with interest charged as though the tax had been underpaid all along.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
Foreign Trust Reporting
Because an InvIT is legally structured as 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 This is a separate obligation from Form 8621 and reports the trust relationship itself, not just the PFIC income. Penalties for failing to file either form are steep, and the complexity trips up even experienced preparers.
Key Risks
InvIT income is relatively stable, but stable isn’t guaranteed.
Interest Rate Sensitivity
Assets with long, predictable cash flows behave a lot like bonds. When rates rise, their relative attractiveness drops and market prices tend to fall. An InvIT operating near the 70% borrowing limit takes a double hit, because refinancing costs climb while unit prices sag. Core assets like 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
Indian InvIT distributions are paid in rupees. For a US investor, every payout and every unit sale must be converted back to dollars. If the rupee weakens against the dollar during your holding period, returns shrink even if the InvIT itself performed well. Hedging is possible through forwards and options but expensive and impractical for most retail investors. Over long periods, currency movements can change total return meaningfully in either direction.
Concession and Regulatory Risk
Many infrastructure assets operate under government concession agreements with fixed 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. Changes to toll rates, tariff structures, or environmental rules can also hit profitability, and political risk sits in the background of anything tied to government contracts.
Concentration Risk
Some InvITs hold only a handful of assets in a single sector. A trust that owns three toll roads in one region is heavily exposed to local traffic, the regional economy, and state-level regulatory decisions. Larger, more diversified InvITs spanning multiple sectors and geographies spread the risk better, though even the biggest trusts are concentrated compared to a broad equity index fund.
How InvITs Compare to REITs
Both use the same pass-through trust structure and share the 90% distribution requirement. The differences come down to what’s inside the trust and how long the cash flows last.
REITs hold commercial real estate: offices, malls, warehouses, and hotels. Tenants sign leases that typically run 5 to 15 years, sometimes up to 30 for anchor tenants. The real estate market is competitive, and vacancy is a constant concern. InvITs hold infrastructure with concessions or long-term contracts that can stretch 20 to 60 years. A toll road concession lasting half a century offers visibility into future cash flows that a five-year office lease can’t match.
That longer duration cuts both ways. InvIT cash flows are more predictable, but the assets are also less flexible. You can renovate an office building or swap tenants; you can’t easily repurpose a highway. REITs tend to be 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 usually offer yields above what government bonds pay.
How to Invest in InvITs
Public InvIT units trade on Indian stock exchanges like the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE), just like ordinary stocks. With a brokerage account that has access to Indian markets, you can buy and sell throughout the trading day at market prices. For Indian residents, this is straightforward through any standard demat account.
Units can also be bought during an initial public offering, when the InvIT first offers units at a fixed price or within a price band before secondary trading begins. IPO subscriptions lock up your capital until listing but sometimes give a slight discount to the eventual market price.
US investors face an extra layer of friction. Most major US brokerages don’t offer direct access to Indian exchanges, so you’d typically need an account with an international broker or a platform that supports Indian equities. Add in currency conversion costs, the tax complexity above, and the need for specialized tax preparation, and the compliance costs alone can eat a meaningful chunk of the income on smaller portfolios.
