Can UCITS ETFs Give Higher Returns Than US-Listed ETFs?

Yes, a UCITS ETF can give an Indian investor a higher return than a US-listed ETF, but UCITS itself does not create alpha. When two funds track the same market, the difference comes from dividend withholding, fees, actual tracking, replication, securities lending, cash management, trading costs, distribution timing, foreign-exchange conversion, bid-ask spreads and the investor's own tax treatment.

The right question is not “Is UCITS better?” It is: Which exact fund leaves more of the same benchmark return in my hands, after every relevant layer of cost and tax?

Can UCITS ETFs Give Higher Returns, Quick Answer

A UCITS ETF can outperform a US ETF tracking the same index over a particular period. It can also underperform. Neither result means the wrapper has found extra market return.

For a fair UCITS ETF returns vs US ETF comparison, start with this structure:

ETF NAV total return ≈ index total return − TER − unrecoverable withholding − portfolio transaction costs + net securities-lending revenue ± replication, sampling, cash, timing and other tracking effects.

Investor return then adjusts that fund return for listing spreads, brokerage, currency conversion and the investor's own Indian tax treatment.

In our matched S&P 500 example, Vanguard S&P 500 ETF (VOO) beat iShares Core S&P 500 UCITS ETF USD (Acc) (CSPX) by about 0.25 to 0.27 percentage point a year over the common one-, three- and five-year periods ended 31 July 2026. That is a historical fund-NAV result before an Indian investor's tax and trading costs, not a permanent forecast.

The result can change at the investor level. VOO's published total return assumes distributions are fully reinvested before investor tax. An Indian investor may have US tax withheld from those cash distributions and may owe Indian tax, with foreign tax credit subject to eligibility and documentation. CSPX accumulates income inside the fund after its own portfolio-level withholding. These taxes sit at different layers and must not be casually netted against each other.

For the broader wrapper decision, first read UCITS ETFs vs US-listed ETFs.

Same Index Does Not Always Mean the Same Investor Return

An index is a rule book and a calculated return series. The S&P Dow Jones Indices overview describes the S&P 500 as a gauge of large-cap US equities; an ETF is a real portfolio that tries to deliver that exposure after real-world frictions. An investor owns the ETF through a broker and adds another layer of frictions.

The return chain is therefore:

Two funds can therefore own essentially the same S&P 500 basket and still deliver different returns. Even their stated benchmark numbers may differ if one issuer uses a gross total-return index and another a net total-return convention.

Plain-English definition: total return

Total return includes price movement and dividends, assuming dividends are reinvested. Price return ignores dividends. An accumulating ETF's price already reflects retained income; a distributing ETF's price does not include cash that has left the fund.

“US-listed” and “US-domiciled” are also not synonyms. A security's exchange tells you where it trades; its domicile tells you which legal and tax wrapper it uses. VOO happens to be both US-listed and US-domiciled. CSPX is Irish-domiciled and has several exchange tickers. The domicile can also matter for non-return issues such as US estate-tax exposure; see US estate tax and global ETFs for Indian investors.

The ETF Net-Return Equation

For a fund measured in its base currency:

Rfund,NAV≈Rindex,total−TER−Wunrecoverable−Cportfolio trading+Lnet lending±Ereplication,cash,timing,otherR_{fund,NAV} \approx R_{index,total} - TER - W_{unrecoverable} - C_{portfolio\ trading} + L_{net\ lending} \pm E_{replication,cash,timing,other}

Where:

For an Indian investor comparing USD fund returns in INR:

RINR,pre-tax=(1+RUSD)×USDINRendUSDINRstart−1R_{INR,pre\text{-}tax}=(1+R_{USD})\times\frac{USDINR_{end}}{USDINR_{start}}-1

The investor's realised outcome then depends on the exact buy and sell prices, brokerage, FX/remittance costs, cash-distribution reinvestment and Indian tax. Taxes cannot always be represented by one neat annual subtraction because their timing differs.

A simple rupee perspective

On ₹1,00,000, a 0.04-percentage-point annual TER difference is only about ₹40 in year one before compounding. A 0.50% combined FX and execution cost is ₹500. Small recurring differences matter over decades, but a poor conversion rate or wide spread can dominate several years of TER savings.

Dividend Withholding and Tax Drag

Dividend tax drag is usually measured against the dividend yield, not against the whole portfolio.

If the portfolio yields 1.5% and one structure loses 10 percentage points more of each dividend than another, the approximate annual return effect is:

1.5%×(25%−15%)=0.15%1.5\% \times (25\%-15\%)=0.15\%

That is 0.15 percentage point, not 10% of the portfolio.

If the higher-withholding fund also has a TER that is 0.04 percentage point higher, the simple pre-other-cost gap becomes about 0.19 percentage point. Actual tracking can differ because dividend yields, treaty eligibility, lending income, cash and portfolio trading vary.

For a detailed explanation of these different withholding layers, read How Dividend Tax Works in US-Listed and UCITS ETFs for Indians.

Do not mix the 25% and 15% layers

The IRS treaty table lists a 25% general US dividend rate for an eligible Indian resident and 15% for an eligible Irish resident, subject to the treaty, documentation and limitation-on-benefits rules. But those figures may apply to different recipients in a VOO-versus-CSPX chain:

This is why “CSPX pays 15%, VOO pays 25%, so CSPX must return more” is incomplete. At the fund-NAV layer, VOO generally receives US corporate dividends without non-resident withholding, while CSPX can suffer withholding inside the Irish fund. At the Indian-investor layer, VOO's distribution can suffer US withholding; CSPX's accumulating share class pays no cash distribution to that investor.

For intuition only, a 1.5% yield and a 15% internal CSPX haircut imply about 0.225 percentage point of fund-level drag. Add CSPX's 0.07% TER versus VOO's 0.03%, and the rough fund-level disadvantage becomes 0.265 percentage point before other tracking effects. That is close to the historical one-, three- and five-year gaps below, but it is not proof of causation.

Foreign tax credit is not automatic economic recovery

An eligible Indian resident may claim credit for qualifying foreign tax, subject to Indian rules, limits, evidence and timely filing. The Income Tax Department's Form 67 guide explains the filing route. Credit may reduce Indian tax; it does not necessarily put the withheld cash back into the ETF on the distribution date.

Tax withheld inside CSPX was borne by the fund, not directly by the Indian unitholder. It is generally not the same as tax shown as withheld from that investor's own VOO dividend. Whether any tax is creditable depends on the legal taxpayer, the income character and current law.

Expense Ratio vs Tracking Difference

TER is a stated fee. Tracking difference is the fund's actual result relative to its stated benchmark.

For clarity, this chapter uses:

Tracking difference = Fund total return - Benchmark total return

A tracking difference of −0.20 percentage point means the fund lagged the selected benchmark by 0.20 percentage point. Some providers use the opposite sign, so always check the definition.

Tracking difference absorbs more than TER:

• dividend withholding and tax assumptions;
• portfolio trading and rebalancing;
• sampling or replication choices;
• cash balances and futures;
• securities-lending revenue;
• index and fund valuation timing; and
• operational and corporate-action effects.

BlackRock's iShares VII annual report explicitly separates TER from direct trading costs and identifies net income/tax and investment techniques as tracking drivers. For the year ended 31 July 2025, it reported CSPX's NAV return at 16.03% versus 15.87% for its stated benchmark, a positive difference despite the fee. That can happen when the fund's actual withholding, lending, cash or execution differs from the assumptions embedded in the benchmark.

Do not compare VOO's tracking difference to CSPX's without checking the benchmark convention. A gross S&P 500 total-return series, a net series and an issuer-specific stated benchmark can produce different gaps even when the funds own the same securities.

Accumulation, Distribution, and Reinvestment Assumptions

CSPX is an accumulating share class. VOO distributes dividends quarterly.

An accumulating ETF does not manufacture a higher total return and is not automatically tax-free. If a distributing fund's dividends are reinvested immediately at no cost and with no tax leakage, its total return can match an otherwise identical accumulating fund. The economic differences appear when:

• withholding reduces the cash reaching the investor;
• the investor pays additional tax;
• reinvestment is delayed;
• fractional shares are unavailable;
• reinvestment incurs brokerage or spread; or
• cash is spent instead of reinvested.

For a valid CSPX vs VOO returns comparison, CSPX's NAV growth must be compared with VOO's NAV total return with distributions reinvested. Comparing the CSPX price with the VOO price alone would wrongly omit VOO's cash distributions.

Read accumulating vs distributing ETFs for the cash-flow and tax implications.

Currency, Listing, NAV, and Market-Price Effects

Trading currency is not economic exposure

The same CSPX share class, ISIN IE00B5BMR087, trades under multiple tickers and currencies. BlackRock lists CSPX in USD and CSP1 in GBP on the London Stock Exchange, and SXR8 in EUR on Xetra. The portfolio is still mainly exposed to US large-cap companies. Buying the EUR ticker does not turn the underlying equity exposure into euros or hedge USD/INR risk.

Ticker symbols are exchange-specific identifiers. Confirm the ISIN, share class, domicile and income policy, not just a familiar ticker.

NAV return and market-price return are not identical

• NAV values the fund's underlying assets at its valuation point.
• Market price is what buyers and sellers agree on during exchange hours.
• The difference is a premium or discount to NAV.
• A bid-ask spread creates an additional entry or exit cost.

Different market hours create false short-term gaps

London may close before New York. A CSPX exchange price can therefore reflect an earlier information set than VOO's US close. On volatile days, a same-calendar-date price chart can make one ETF appear to lead or lag simply because the clocks differ. Month-end NAV total returns reduce, not eliminate this problem.

How to Compare Multi-Year Returns Fairly

Do not compare:

• a price-only return with a total return;
• different start or end dates;
• USD for one fund with INR, GBP or EUR for the other;
• an accumulating fund with a distributing fund whose distributions were not reinvested;
• market-price return for one fund with NAV return for the other;
• an index's gross return with a fund's net return and call the gap a fee; or
• annualised returns with cumulative returns without relabelling them.

Use this fair-comparison checklist:

1. Confirm the funds hold the same economic exposure and compatible index methodology.
2. Check whether the index series is price, gross total return or net total return.
3. Use the same start and end dates for each paired result.
4. Use NAV against NAV, or market price against market price for a deliberate execution study.
5. Use total returns with all distributions reinvested.
6. Convert both funds into the same currency with one FX source and matching dates.
7. Compare the exact share classes by ISIN, income policy and domicile.
8. Label annualised and cumulative figures correctly.
9. Separate fund-level return from spreads, brokerage, remittance costs and investor tax.
10. Record the source date, rounding method and any inception or data mismatch.

Matched ETF Case Study, CSPX vs VOO

CSPX and VOO both provide exposure to the S&P 500, but their dividends travel through different tax and reinvestment routes.

CSPX receives dividends inside an Irish-domiciled accumulating fund. After any fund-level withholding, the remaining income is reinvested automatically. The investor does not have to place a separate reinvestment order.

VOO receives the dividends as a US-domiciled fund and distributes them to the investor. An eligible Indian investor may receive the dividend after US withholding. Reinvesting that remaining cash may involve brokerage, bid-ask spread and a delay before the money returns to the market.

This means we need two separate comparisons:

1. Fund-level NAV return, which shows how the two funds performed before the investor's personal tax and trading costs.
2. Indian investor return, which considers how much of each dividend can actually be reinvested.

Fund identity check

Both funds provide substantially the same S&P 500 exposure. However, their benchmark-return conventions, dividend treatment and valuation cut-offs may not be identical. The cleanest fund-level comparison therefore uses each fund's USD NAV total return over the same period.

See physical vs synthetic UCITS ETFs for how replication can affect tracking, and Ireland vs Luxembourg UCITS ETFs for why domicile must be checked fund by fund.

First comparison, what the issuer-reported returns show

These figures do not show only the TER difference. They include the fund-level effect of expenses, withholding inside the fund, portfolio trading, cash management, securities lending and other tracking effects.

However, they still do not show what an Indian investor necessarily earned.

VOO's published NAV total return assumes that every distribution is reinvested without deducting the investor's personal withholding tax, brokerage or bid-ask spread. This is the standard way to calculate a fund's total return, but it is not the same as the amount an Indian investor can actually reinvest.

CSPX's published NAV already reflects the dividend withholding suffered inside the Irish fund. Because CSPX is accumulating, the remaining dividend is reinvested internally without requiring a separate order from the investor.

Therefore, the historical table is useful for evaluating fund-level tracking, but it should not be presented as the final after-tax winner for an Indian investor.

Second comparison, what an Indian investor may actually retain

Consider a simplified one-year example.

Assume both funds start with an investment worth $10,000 and the S&P 500 produces:

• Price appreciation of 8.50%
• Gross dividend yield of 1.50%
• Gross total return of 10.00%

Also assume:

• CSPX suffers 15% withholding on underlying US dividends inside the Irish fund.
• VOO distributions to an eligible Indian investor suffer 25% US withholding.
• CSPX has a TER of 0.07%.
• VOO has an expense ratio of 0.03%.
• Reinvesting VOO dividends costs 0.25% brokerage, capped at $25.
• The reinvestment order suffers an estimated execution cost of 0.03% because of the bid-ask spread.
• Fractional shares are available.
• Additional Indian tax, foreign tax credit, FX charges and other tracking effects are excluded for now.

These are simplifying assumptions, not a forecast of either fund's actual return.

How the CSPX dividend is reinvested

The underlying companies pay a gross dividend of:

$10,000 × 1.50% = $150

If 15% is withheld before the dividend reaches the Irish fund:

Withholding inside the fund = $150 × 15% = $22.50

The amount remaining inside CSPX is:

$150 − $22.50 = $127.50

That $127.50 is reinvested automatically inside the accumulating fund. The investor does not need to place another trade or pay separate brokerage on this reinvestment.

CSPX's approximate annual fund charge is:

$10,000 × 0.07% = $7

Its simplified ending value becomes:

**Starting investment $10,000

• Price gain $850
• Net dividend reinvested $127.50
  − Fund charge $7
  = $10,970.50**

The simplified investor return is therefore approximately 9.705%.

There is no separate investor brokerage charge for reinvesting the dividend. This does not mean the fund operates without trading costs. Any internal portfolio dealing costs are reflected in CSPX's NAV and tracking difference.

How the VOO dividend is reinvested

VOO also receives a gross dividend of $150. Because VOO is US-domiciled, the 25% Indian treaty rate is not deducted when US companies pay dividends into VOO. It may apply when VOO distributes the dividend to the Indian investor.

The US withholding on the investor's distribution is:

$150 × 25% = $37.50

The cash reaching the investor is:

$150 − $37.50 = $112.50

If the investor reinvests this amount through a broker charging 0.25%:

Reinvestment brokerage = $112.50 × 0.25% = approximately $0.28

The $25 cap does not matter in this example because 0.25% of the order is far below $25.

Assuming a further 0.03% execution cost from the bid-ask spread:

Estimated spread cost = $112.50 × 0.03% = approximately $0.03

The amount that is effectively reinvested is therefore:

$112.50 − $0.28 − $0.03 = $112.19

VOO's approximate annual fund charge is:

$10,000 × 0.03% = $3

Its simplified ending value becomes:

**Starting investment $10,000

• Price gain $850
• Net dividend reinvested $112.19
  − Fund charge $3
  = $10,959.19**

The simplified investor return is therefore approximately 9.592%.

Worked-example result

Under these assumptions, CSPX finishes approximately $11.31 ahead on a $10,000 investment, equivalent to about 0.11 percentage point in one year.

On a ₹1,00,000 equivalent investment, the difference would be approximately ₹113 before additional Indian tax and FX costs.

Why CSPX moves ahead in this example

The difference can be understood in three simple steps.

First, CSPX loses 15% of a 1.50% dividend yield:

1.50% × 15% = 0.225 percentage point of tax drag

VOO's Indian investor loses 25% of the same dividend before reinvestment:

1.50% × 25% = 0.375 percentage point of tax drag

This gives CSPX a dividend-retention advantage of:

0.375% − 0.225% = 0.15 percentage point

Second, VOO has a 0.04-percentage-point fee advantage:

0.07% − 0.03% = 0.04 percentage point

After accounting for the fee difference, CSPX's structural advantage falls to approximately:

0.15% − 0.04% = 0.11 percentage point

Finally, VOO's dividend reinvestment brokerage and spread reduce its result slightly further.

The key point is that a 25% dividend-withholding rate does not reduce the entire portfolio return by 25%. It applies only to the dividend. With a 1.50% dividend yield, 25% withholding creates a portfolio-level drag of approximately 0.375 percentage point.

Important limitations of the worked example

This illustration does not prove that CSPX will always outperform VOO for an Indian investor.

The result changes if:

• The S&P 500 dividend yield changes.
• The applicable withholding rate is different.
• The investor can claim and fully use a foreign tax credit.
• The broker offers free automatic dividend reinvestment.
• A minimum brokerage charge applies.
• Fractional shares are unavailable.
• The investor leaves small dividends in cash before reinvesting them.
• Actual bid-ask spreads differ.
• CSPX or VOO records a different tracking difference.
• Indian dividend or capital-gains tax rules change.

Foreign tax credit is especially important. US tax withheld from a VOO dividend may be creditable against qualifying Indian tax, subject to applicable limits, documentation and Form 67. However, the credit does not necessarily restore the withheld cash to the brokerage account on the dividend date. Unless the investor funds the difference separately, only the post-withholding cash is immediately available for reinvestment.

The tax withheld inside CSPX is borne by the fund. It is generally not the same as tax withheld directly in the Indian investor's name. CSPX's accumulating structure is also not tax-free. The investor may face Indian capital-gains tax when the units are sold and may have foreign-asset reporting obligations.

Return Comparison in USD and INR

Currency conversion should be kept separate from the fund and tax comparison.

The simple rule is:

INR ending value = Starting investment × USD fund growth × USD/INR currency movement

If the dollar becomes more expensive in rupee terms, it increases the INR value of the investment. If the rupee strengthens, it reduces the translated INR return.

A simple five-year example

CSPX returned 12.55% a year in USD over the five years ended 31 July 2026.

Over five years, ₹1 invested at 12.55% a year would grow to approximately ₹1.806 in USD terms.

During the same period, USD/INR increased from 74.34 to 95.38.

This means each dollar became approximately:

95.38 divided by 74.34 = 1.283 times as valuable in rupee terms

We now combine the investment growth and currency movement:

1.806 × 1.283 = 2.317

Therefore:

₹1,00,000 × 2.317 = approximately ₹2,31,719

This represents:

• A cumulative INR return of approximately 131.72%
• An annualised INR return of approximately 18.30%

The same method is applied to both funds.

Published fund returns translated into INR

These remain issuer-style, pre-investor-tax returns. The VOO figures still assume that distributions were fully reinvested before personal withholding tax, brokerage and spread costs.

The table therefore answers this question:

How did the two funds' published USD returns look after translating them into INR?

It does not answer:

How much did an Indian investor retain after dividend withholding, reinvestment expenses and Indian tax?

Because the same USD/INR movement is applied to both funds, currency translation does not change which fund leads in the published-return table. It simply increases or reduces the INR return of both.

The correct comparison order

For an Indian investor, the comparison should be completed in this order:

1. Start with each fund's USD NAV total return.
2. For VOO, adjust for the actual tax withheld from distributions.
3. Deduct any brokerage, spread and cash drag involved in reinvesting those distributions.
4. For CSPX, remember that fund-level withholding and internal costs are already reflected in NAV.
5. Convert both resulting USD values into INR using the same dates and FX source.
6. Apply the investor's Indian tax treatment, including any eligible foreign tax credit.

This prevents fund-level returns, investor-level withholding and currency movement from being mixed into one confusing number.

What Past Outperformance Can and Cannot Tell You

The matched table tells us that VOO's fund-level NAV total return was modestly higher over the periods tested. It does not establish that VOO will leave every Indian investor with more money.

Past data can help evaluate:

• whether the observed gap is broadly consistent with fees and tax structure;
• whether tracking was stable or erratic;
• whether the fund repeatedly lagged its benchmark by more than its TER; and
• whether execution and FX costs could overwhelm a small return advantage.

Past data cannot lock in:

• future dividend yields or treaty rates;
• a fund's future tax eligibility;
• future securities-lending revenue;
• future tracking difference or spread;
• the investor's future Indian tax rate or foreign tax credit; or
• which listing a broker will make available at a competitive price.

There is also survivorship bias: CSPX and VOO are large funds that remained live and successful. Choosing two survivors does not describe every UCITS or US ETF. Their inception dates differ by several months, which is why this chapter uses common periods rather than since-inception figures. Source tables round returns, and NAV cut-offs can differ slightly even at the same month-end.

A practical decision rule

Do not choose the wrapper from one historical return column. Estimate your all-in result in this order:

1. Confirm the index exposure and share class.
2. Estimate structural fund drag from withholding, TER and observed tracking difference.
3. Add your broker's spread, commissions, FX markup and remittance costs.
4. Model distribution reinvestment and investor-level tax, including realistic foreign tax credit treatment.
5. Consider non-return issues: broker access, liquidity, operational convenience, reporting and estate-tax implications.

A lower-TER fund can lose after tax. A tax-efficient wrapper can lose after spreads and FX. The best choice depends on the investor's actual route, not the label on the fund. Use the 10-point checklist for choosing a UCITS ETF to evaluate these factors together.
