The Portfolio Investment Scheme (PIS) is the RBI-regulated route, operating under FEMA, that lets NRIs buy and sell listed Indian equities through recognised stock exchanges. It's specific, it's rule-bound, and it doesn't apply to everything you might want to invest in.
This guide breaks down what PIS actually covers, its account types, the limits you need to respect, and where mutual funds or other routes might serve you better without the extra paperwork.
Key Takeaways
- PIS applies only to direct equity and debenture trading on Indian exchanges, not mutual funds
- NRE-linked PIS accounts are fully repatriable, with no remittance restrictions
- NRO-linked accounts cap remittance at USD 1 million per financial year
- NRI ownership caps sit at under 10% individually and 24% in aggregate across all investors
- Mutual funds via the folio route need no PIS permission or demat account at all
What is a Portfolio Investment Scheme (PIS) for NRIs?
PIS is a facility under the Foreign Exchange Management Act, 1999, specifically Schedule III of the Foreign Exchange Management (Non-debt Instruments) Rules, 2019. Cambridge's explainer on what the Portfolio Investment Scheme is covers the basics, and a separate note sets out whether there is a ceiling on PIS investments. It permits NRIs and OCIs (a category that now includes those formerly classified as PIOs) to purchase and sell shares and convertible debentures of listed Indian companies through recognised stock exchanges.
Every PIS account must be linked to a bank branch authorised by the RBI as a designated dealer. That branch reports each transaction to the RBI, which is how the regulator tracks aggregate NRI holding in any company and keeps it within permitted limits.
Who Can Use PIS
Eligibility under Schedule III currently covers:
- NRIs investing on their own account
- OCIs, including those who previously held PIO cards
- FIIs, historically, though these largely operate under separate registration frameworks today
Overseas Corporate Bodies (OCBs) have been barred from fresh investment under this scheme since 2003.
Scope matters too: PIS applies only to direct equity and debenture trading on exchanges only. Mutual funds and Portfolio Management Services (PMS) follow entirely different routes, which we'll get to shortly.
This is exactly the kind of distinction that gets lost when NRIs treat PIS as a blanket requirement. At Cambridge Wealth, the conversation starts with your stated goals, timelines and tax residency. From there it becomes clear where PIS actually fits, rather than assuming every NRI needs one from day one.
Types of PIS Accounts: NRE vs NRO
Not all PIS accounts work the same way. The one you need depends on where your investment money comes from.
PIS accounts come in two types, tied to the source of your investment funds:
| Account Type | Source of Funds | Repatriability | Repatriation Limit |
|---|---|---|---|
| NRE-Linked PIS | Foreign earnings | Fully repatriable | No annual ceiling |
| NRO-Linked PIS | India-sourced income (rent, dividends, interest) | Restricted | USD 1 million per financial year |
The NRE-linked account suits money earned abroad, since both principal and profits qualify for repatriation. The NRO-linked account applies to India-sourced income such as rent or dividends, where repatriation stays subject to taxes, documentation, and the overall USD 1 million ceiling, not a per-account allowance.
A few practical points worth knowing before you pick one:
- You can appoint only one designated bank per account type (NRE or NRO) for PIS purposes
- Switching banks means closing your existing PIS account first, then opening a fresh one elsewhere
- Funds moving from your bank account into your trading account under PIS typically take up to a working day, slower than a direct NRO/non-PIS transfer
There's no single published RBI count of banks offering PIS. Most major AD Category-I banks, including SBI, HDFC Bank, ICICI Bank, and Axis Bank, provide the service.
Comparing their fee structures before committing is a smart first move, which we'll cover in the account-opening section.
Investment Limits, Restrictions & Regulatory Compliance under PIS
PIS comes with hard ceilings, and breaching them triggers an immediate forced sell-down.
Ownership Caps
Under the current Schedule III framework, effective from mid-2026:
- An individual NRI or OCI cannot hold 10% or more of a company's fully diluted paid-up equity capital
- The combined holding of all such individuals in one company cannot exceed 24%
- If the individual threshold is breached, the excess must be divested within five trading days
These figures replace the older 5% individual / 10% aggregate structure many NRIs still assume applies, per the Ministry of Finance's NDI Third Amendment Rules. The RBI monitors this daily, and once a company's aggregate NRI holding hits the ceiling, further NRI buying in that stock gets frozen automatically.
Sectors Where PIS Investment Is Restricted
Certain sectors carry outright prohibitions or heavy conditions under Rule 9:
- Chit funds (except NRI/OCI investment on a non-repatriation basis)
- Nidhi companies
- Real estate business, though this excludes construction of housing and commercial infrastructure
- Trading in Transferable Development Rights (TDRs)
- Lottery, gambling, and betting businesses
- Manufacturing of tobacco products
Agriculture and plantation activities aren't blanket-prohibited, contrary to popular belief. Specific categories, such as tea, coffee, rubber, and cardamom plantations, remain permitted under sectoral conditions.
Trading Restrictions
Three activity rules trip up newer PIS users constantly:
- No intraday trading – shares bought must be delivered, and shares sold must come from actual delivery, so same-day square-offs aren't allowed
- No short selling – you can't sell what you don't already hold
- No joint PIS accounts – each PIS account is held individually
One rule catches many NRIs off guard: once an NRI becomes a resident Indian again, the PIS-linked demat and trading accounts must be converted or closed, with holdings shifted to a resident account.
Opening a PIS Account: Process and Documentation
The sequence is fairly linear once you know the order.
- Open an NRE or NRO savings account with your chosen designated bank
- Apply for PIS permission through that same bank, which acts on the RBI's behalf here
- Link a demat and trading account once permission is granted
Documents You'll Typically Need
- PAN card
- Passport with a valid visa or residence permit
- FATCA/FEMA declarations
- Overseas address proof
- Cancelled cheque or recent bank statement
Budgeting for Costs
PIS charges vary quite a bit by bank and broker, so it pays to compare before signing up. For example:
- Some banks charge ₹0–1,000 for PIS issuance and ₹0–1,500 annually for maintenance, depending on your relationship tier
- Per-trade reporting charges can run ₹0–150 per trade date, charged separately for purchases and sales
- Brokerage for PIS-linked trading can range from a flat fee per order to a percentage of trade value
There's no RBI-mandated standard here, so getting a fee schedule in writing from your bank before opening the account saves surprises later.
PIS vs Non-PIS vs Mutual Funds: Choosing the Right Investment Route
Here's where a lot of NRIs overpay for complexity they don't need.
The Non-PIS Route
If you're investing NRO funds in mutual funds, bonds, or other non-repatriable instruments, you often don't need a PIS account at all. The non-PIS NRO route skips RBI transaction reporting and the PIS permission letter entirely, which makes it noticeably simpler for many use cases.
Mutual Funds Without PIS or Demat
Investing through the folio or Statement of Account (SOA) route means you don't need a PIS certificate or even a demat account. Units sit in a folio, serviced through periodic statements, making this the most accessible entry point for NRIs who want diversified exposure without picking individual stocks.
Comparing the Cost Picture
PIS carries a stack of charges:
- Bank issuance fees for account setup
- Annual maintenance charges
- Per-trade reporting fees
- Brokerage on each transaction
- Demat AMC charges
Mutual funds, by contrast, charge a Total Expense Ratio (TER) deducted directly from NAV. Direct plans carry a lower base expense ratio than regular plans since they exclude distributor commission.
For an NRI comparing the two, PIS-linked direct equity investing tends to carry a higher combined annual cost load than a mutual fund folio. The layered bank and broker fees simply add up faster than a single expense ratio.
This is precisely the decision point where a one-size-fits-all answer falls apart. Cambridge Wealth's 108-point research framework evaluates products across direct equity via PIS, mutual funds and PMS, so the options you review are assessed against your repatriation needs, tax residency and stated goals rather than defaulting everyone into the same account structure.
Common Mistakes NRIs Make with PIS Investments
Even NRIs who understand the mechanics of PIS trip up on a few recurring issues.
Assuming PIS is mandatory for everything. It isn't. Mutual funds, government bonds, and several other instruments are fully accessible without ever opening a PIS account.
Ignoring DTAA benefits and holding-period rules. For listed equity sold after July 23, 2024, short-term gains (held 12 months or less) attract a 20% rate under Section 111A. Long-term gains above ₹1,25,000 are taxed at 12.5% without indexation, according to the Income Tax Department's rules on capital gains from share sales.
Many NRIs skip claiming Double Taxation Avoidance Agreement (DTAA) relief simply because they don't have a Tax Residency Certificate ready, leaving money on the table unnecessarily.
Overlooking currency fluctuation risk on repatriation. A rupee that weakens against your home currency between the time you invest and the time you repatriate can erase gains that looked solid in INR terms. A falling rupee directly impacts NRI investor portfolios at the point of conversion, not just on paper.
Frequently Asked Questions
What are the investment schemes for NRI in India?
The main routes are PIS for direct equities, non-PIS/NRO accounts for bonds and non-repatriable instruments, mutual funds via the folio route, PMS, NPS, and government bonds. Each serves different repatriation and risk needs.
Is PIS mandatory for NRIs?
No. PIS is required only for direct equity or debenture trading on stock exchanges. NRIs can invest in mutual funds and several other instruments through a regular NRE or NRO account without ever needing PIS.
Can NRIs in the USA invest in SIPs in India?
Yes, most US-based NRIs can invest in Indian mutual fund SIPs via NRE or NRO accounts. Some AMCs do impose additional FATCA-related declarations for US residents, so check fund-specific policies before investing.
Can NRIs have multiple PIS accounts?
Only one PIS account per category, NRE or NRO, can be held with a single designated bank. Switching banks requires closing the existing PIS account before opening a new one elsewhere.
What is the minimum balance required for a PIS account?
There's no RBI-mandated minimum balance for the PIS account itself, though the linked NRE or NRO savings account may carry its own bank-specific minimum balance requirement.
Do NRIs need a PIS certificate to invest in mutual funds?
No. A PIS certificate isn't required for mutual fund investments made through the non-PIS NRE/NRO route or the folio-based method, since these don't involve exchange-traded equity purchases.
