UCITS stands for Undertakings for Collective Investment in Transferable Securities. UCITS is a set of EU rules for investment funds. Any ETF or mutual fund that follows these rules is a UCITS fund, whatever it holds, including US stocks. Most large UCITS ETFs, such as CSPX, are domiciled in Ireland or Luxembourg.
Indian investors can invest in UCITS funds through a global brokerage account, under the RBI's Liberalised Remittance Scheme (LRS).

Who regulates UCITS funds?
A UCITS fund is regulated by the financial regulator of the EU or EEA country where the UCITS fund is domiciled. The Central Bank of Ireland regulates Irish UCITS funds. The Commission de Surveillance du Secteur Financier (CSSF) regulates Luxembourg UCITS funds. For how Irish and Luxembourg UCITS funds differ for Indian investors, see Ireland vs Luxembourg UCITS.
Every UCITS regulator applies the same law, Directive 2009/65/EC, known as the UCITS Directive. This post follows the consolidated text of April 2026.
A UCITS fund authorised in one EU country can be sold across the EU under the same rules. Fund managers call this the UCITS passport.
Note: the UCITS rules date back to Directive 85/611/EEC of 1985. Directive 2009/65/EC replaced it.
What rules does a UCITS fund have to follow?
A UCITS fund has to follow five core rules, all set out in the UCITS Directive (Directive 2009/65/EC). The best known is the 5/10/40 rule: a UCITS fund can put no more than 5% of its assets in one issuer, up to 10% where its home country allows, and holdings above 5% together cannot exceed 40% of the fund.
| UCITS rule | What the UCITS Directive says | Where it is set | What it means for you |
|---|---|---|---|
| 5/10/40 rule | A UCITS fund can invest no more than 5% of its assets in securities of one issuer. EU countries can raise this to 10%, but holdings above 5% together cannot exceed 40% of assets | Article 52 of the UCITS Directive | No single company can dominate the fund |
| Index fund exception | A UCITS fund tracking a recognised index can hold up to 20% in one issuer, and up to 35% in one issuer in exceptional market conditions | Article 53 of the UCITS Directive | An S&P 500 UCITS ETF can hold Nvidia or Apple at index weight |
| Redemption on request | A UCITS fund must buy back units at the request of any unit holder. For a UCITS ETF, keeping the exchange price close to NAV counts as equivalent | Article 84 of the UCITS Directive | You exit a UCITS mutual fund by redeeming with the fund, and a UCITS ETF by selling it on the exchange. A fund can suspend redemptions temporarily |
| Leverage limit | A UCITS fund cannot borrow, except temporarily up to 10% of its assets where its home country allows it. Its global exposure to derivatives cannot exceed the total net value of its portfolio | Article 51 and Article 83 of the UCITS Directive | Limits how far the fund can magnify gains and losses |
| Independent depositary | A UCITS fund appoints a single depositary to hold its assets, and the depositary can reuse them only under strict conditions | Article 22 of the UCITS Directive | Fund assets sit apart from the fund manager |
For how these UCITS rules apply to S&P 500 and Nasdaq 100 trackers, see What are UCITS ETFs?.
Is a UCITS fund an ETF or a mutual fund?
Both. A UCITS fund can be an exchange-traded fund (ETF) or a mutual fund, and both follow the same UCITS Directive.
The difference between a UCITS ETF and a UCITS mutual fund is how you buy and sell it.
| UCITS ETF | UCITS mutual fund | |
|---|---|---|
| Where you buy it | On a stock exchange, such as the London Stock Exchange or Xetra | From the fund manager or a distributor |
| Price you get | Live market price during trading hours | Net asset value (NAV), set after the dealing cut-off |
| When you can trade | Any time the exchange is open | On the fund's dealing days |
| Rulebook | UCITS Directive (2009/65/EC) | UCITS Directive (2009/65/EC) |
For fees, minimums and when a UCITS mutual fund makes more sense than a UCITS ETF, see UCITS mutual funds vs UCITS ETFs.
How can you check if a fund is UCITS?
Four checks confirm whether a fund is UCITS. All four use the fund provider's own documents or the regulator's register.
- The fund name. UCITS ETFs usually carry "UCITS" in the name, such as iShares Core S&P 500 UCITS ETF. Many UCITS mutual funds don't, so rely on the next three checks for them.
- The key facts. The fund provider's product page states UCITS status, domicile and the issuing company.
- The KID. A UCITS fund sold to EU retail investors publishes a Key Information Document.
- The regulator. The fund's home regulator authorises it, and the prospectus names that regulator, such as the Central Bank of Ireland for Irish funds.
Note: an ISIN starting with IE or LU shows that a fund is domiciled in Ireland or Luxembourg. It does not prove the fund is UCITS, because Ireland and Luxembourg also host non-UCITS funds.
Example. Suppose you are about to buy CSPX and want to confirm it is a UCITS fund. Here is what the iShares product page for CSPX shows, as of 21 October 2026.
| What CSPX shows | |
|---|---|
| Fund name | iShares Core S&P 500 UCITS ETF USD (Acc) |
| UCITS status | UCITS: Yes |
| ISIN | IE00B5BMR087 |
| Domicile | Ireland |
| Issuer and regulator | iShares VII plc, authorised by the Central Bank of Ireland |
| Listings | CSPX (USD) and CSP1 (GBP) on the London Stock Exchange, SXR8 (EUR) on Xetra |
The result: CSPX passes all four checks. CSPX is an Irish UCITS ETF, and the same fund trades in USD, GBP and EUR under different tickers. The ISIN, IE00B5BMR087, stays the same on every listing.

Are UCITS funds safe?
Yes, UCITS funds are safe. But that does not mean that they are risk-free. The UCITS Directive protects investors from how a fund is run, not from market losses.
| UCITS protects you from | UCITS does not protect you from |
|---|---|
| One company dominating the fund (5/10/40 rule, Article 52) | A fall in the market the fund tracks |
| The fund manager using fund assets (independent depositary, Article 22) | Currency moves between the fund's currency and the rupee |
| Heavy borrowing or derivatives leverage | Tracking difference between the fund and its index |
| Being locked in: you can redeem a UCITS mutual fund on request or sell a UCITS ETF on the exchange (except during a temporary suspension) | Wide bid-ask spreads on a thinly traded listing |
Why do Indian investors choose UCITS funds for US exposure?
Indian investors choose Irish UCITS funds to get US market exposure without US estate tax risk. An S&P 500 UCITS ETF such as CSPX holds the same US companies as a US-domiciled S&P 500 ETF, but the investor owns shares of an Irish fund.
| The estate of an Indian resident who is not a US citizen owes US estate tax on US-situated assets above USD 60,000, and must file a US estate tax return once those assets exceed USD 60,000. The US estate tax rate rises to 40% on taxable estates above USD 1 million.A US citizen gets a USD 15 million exemption in 2026. |
|---|
Shares of a US-domiciled ETF count as US-situated assets. Shares of an Irish UCITS fund such as CSPX do not, because CSPX is not a US corporation.
For how the US estate tax is calculated, see US estate tax for Indians and NRIs.
| What changes | US-domiciled S&P 500 ETF | Irish S&P 500 UCITS ETF (CSPX) |
|---|---|---|
| Fund domicile | United States | Ireland |
| Underlying holdings | US companies in the S&P 500 | US companies in the S&P 500 |
| US-situated asset for estate tax | Yes | No |
| US estate tax return needed | When US-situated assets exceed USD 60,000 | Not for the CSPX holding |
| Top US estate tax rate | 40% | Not applicable |
| US dividend withholding tax | 25% for an Indian resident, under the India-US DTAA | 15% paid inside the fund, under the US-Ireland tax treaty |
Accumulating share classes are the second reason.
Many UCITS funds, including CSPX, reinvest dividends instead of paying them out, so an Indian resident has no dividend income from the UCITS fund to pay tax on each year.
For the trade-offs, see UCITS ETFs: accumulating vs distributing.
Lower dividend withholding is the third reason.
An Irish UCITS fund pays 15% US withholding tax on US dividends under the US-Ireland tax treaty.
If you opt for an accumulating share class, this is the only tax you pay on dividends.
If you hold a US-domiciled ETF, dividend payout are taxed at your income tax slab rate.
For how the 15% is applied inside the fund, see How the 15% dividend withholding tax on Irish UCITS works.
Note: If you hold a distributing UCITS, you will end up paying more tax on dividends compared to a US ETF. In terms of tax efficiency on dividend payouts, accumulating UCITS are the best choice.
Can Indians invest in UCITS funds?
Yes. Indian residents can buy UCITS funds under the RBI's Liberalised Remittance Scheme (LRS), which allows a resident individual to remit up to USD 250,000 per financial year for permitted investments.
Indian residents can buy UCITS funds in three ways. With a global investing account, UCITS fund units are held in your own name.
| Route | What you own | Does LRS apply? |
|---|---|---|
| A global investing account in your own name | UCITS fund units, held in your name | Yes |
| A GIFT City platform | UCITS fund units, under the platform's custody arrangement | Yes |
| An Indian fund of funds that invests in a UCITS fund | Units of the Indian fund, not the UCITS fund | Not ordinarily |
Paasa offers the first route. On Paasa, Indian residents can buy UCITS ETFs across USD, GBP and EUR listings, and UCITS mutual funds, in an account in their own name with Interactive Brokers as custodian. Paasa also handles the LRS remittance and prepares the Schedule FA and capital gains reports for the income tax return.
