A growing group of global Indian investors is already choosing UCITS ETFs over US-domiciled ETFs. The reasons are clear: US estate tax can hit US-situs assets hard at higher account sizes, and UCITS structures often leave investors better off on dividend taxation than holding US ETFs directly.
For anyone building a serious overseas portfolio, UCITS has become a natural way to own the S&P 500, Nasdaq-100, and global indices.
Inside those UCITS ETFs there is another decision that matters just as much: the share class. The same fund often comes in two versions, accumulating and distributing. Both track the same index and sit in the same domicile. The difference is only in what happens to dividends, whether they stay invested inside the ETF or keep turning into cash and tax entries each year.
For example, take iShares Core S&P 500 UCITS ETF. Under reasonable long-term return assumptions, an investor who puts USD 50,000 into the accumulating share class (CSPX) and leaves it for ten years might end up with roughly USD 108,000. The distributing share class (IUSA) of the same ETF lands closer to USD 100,000, simply because part of the return keeps going out as taxable dividends each year instead of staying invested in the fund.

What are UCITS ETFs?
UCITS stands for “Undertakings for Collective Investment in Transferable Securities”. For investors, it simply means the fund is set up under a European Union investor-protection regime and can be sold across Europe.
A UCITS ETF is an exchange-traded fund authorised under these rules and listed on a stock exchange. It trades like any other stock, while the ETF itself holds a diversified portfolio that tracks an index such as the S&P 500, Nasdaq-100, or global equity benchmarks.
Where they are based?
Most UCITS ETFs that global investors use are set up in European fund hubs such as Ireland and Luxembourg. These centres specialise in cross-border funds and provide the infrastructure, service providers, and regulation needed to run large international ETFs.
Who supervises them?
The UCITS rules are set at the EU level, but each individual fund is authorised and monitored by the financial regulator in its home country. After a fund is authorised in one EU member state, it can effectively be “passported” across Europe and offered to investors worldwide under the same investor-protection standards.
Before getting into accumulating vs distributing, it helps to quickly see how UCITS ETFs differ from US-listed ETFs for an Indian investor.
US ETFs vs UCITS ETFs: quick comparison
Aspect | US-listed ETF | UCITS ETF |
Domicile | United States | Ireland or Luxembourg in most global funds |
Estate-tax exposure | US estate tax can apply once US-situs assets cross the USD 60,000 threshold | No US estate-tax exposure on the ETF itself because it is non-US domiciled |
Dividend withholding | Around 30% US withholding tax on most US dividends, reduced to 25% under India-US DTAA | Around 15% US withholding at fund level for many Ireland-domiciled UCITS that hold US stocks |
Dividend handling | Mostly distributing share classes that pay out cash dividends | Choice of accumulating share classes that reinvest income or distributing share classes that pay it out |

Accumulating vs distributing UCITS ETFs
Once the UCITS ETF is chosen, the real choice is the share class. Most S&P 500, Nasdaq-100, and global UCITS ETFs come in two lines: accumulating, which keeps dividends inside the fund, and distributing, which pays them out as cash. The index, domicile, and risk are the same in both; only the way income is handled is different.
Accumulating UCITS ETFs
An accumulating (often labelled “Acc” or “Accumulation”) share class retains all income and reinvests it back into the portfolio.
- No cash dividend is declared or paid.
- Income is used to buy more of the underlying stocks or bonds.
- Returns appear as a higher ETF price over time, as everything remains inside the net asset value.
This structure suits investors focused on long-term growth and automatic compounding rather than regular cash flows.
Distributing UCITS ETFs
A distributing share class (often labelled “Dist”, “Income” or “Inc”) pays out the income it receives at set intervals, such as quarterly or semi-annually.
- Dividends are paid as cash into the brokerage account linked to the ETF.
- After the payout is declared, the ETF price typically adjusts down by roughly the amount paid out, since that value leaves the fund.
Taxation: Accumulating vs Distributing
For an Indian resident, both accumulating and distributing UCITS ETFs sit in the same tax bucket as foreign ETFs. When units are sold, any gain over cost is taxed as capital gains under the same rules for both share classes. The only practical difference is timing: distributing ETFs create dividend income each year that is taxed at slab when paid, while accumulating ETFs keep that income inside the fund and push more of the tax into capital gains at exit.
To see why the share class matters, take a simple example.
What you keep after tax: 10-year CSPX (Acc) vs IUSA (Dist)
Illustrative example only, not a forecast.
Item | Accumulating UCITS ETF (e.g. CSPX) | Distributing UCITS ETF (e.g. IUSA) |
Starting investment | USD 100,000 lump sum | USD 100,000 lump sum |
Time horizon | 10 years | 10 years |
Assumed annual return | 8% total (2% dividend yield, 6% price growth) | 8% total (2% dividend yield, 6% price growth) |
Dividend handling | Dividends stay inside the ETF and are reinvested in NAV | Dividends are paid out in cash, then reinvested only after India tax |
Indian tax on dividends | None during the 10 years (no cash dividend received) | Each payout taxed at 30% slab when received |
Indian tax on sale | Long-term capital gains on the gain, taxed at 12.5% at exit | Same 12.5% LTCG rate on the gain at exit |
Total India tax over 10 years (approx) | ~USD 14,000 (single capital-gains bill at the end) | ~USD 22,000 (dividend tax over the years + capital-gains tax at the end) |
Amount left after all India tax (approx) | ~USD 202,000 | ~USD 194,000 |
Approx after-tax return per year | ~7.3% p.a. | ~6.7% p.a. |
With the same USD 100,000 in the same S&P 500 UCITS ETF, the accumulating share class ends up with roughly USD 8,000 more after 10 years, purely because less of the return leaks out each year as taxable dividends.

Conclusion
The choice between accumulating and distributing UCITS ETFs decides how your returns show up: quietly compounding inside the fund, or leaving the portfolio each year as taxable cash.
For most India-resident investors using UCITS ETFs to build long-term global exposure, an accumulating share class is usually the cleaner default. Dividends stay invested, more of the growth is taxed once as long-term capital gains, and the cash flows are simpler to manage.
Distributing share classes still have a place where regular foreign-currency income is the main goal and higher yearly tax is an acceptable trade off. The key is to treat the share-class label as a real structural choice, not a detail in the fund name.
