VOO UK equivalent: what to buy instead of VOO and SPY

VOO is Vanguard's US-listed S&P 500 ETF, and you cannot buy it through a mainstream UK or European broker. The funds that do the same job are Irish-domiciled S&P 500 UCITS ETFs, and domiciled simply means where a fund is legally based. Ireland is the standard home for European index funds, for tax reasons this page comes back to.

The mapping is easy to remember because the American tickers all do the same thing anyway. VOO, IVV and SPY all track the S&P 500, the index of roughly 500 of the largest US companies. CSPX, VUSA and VUAG track exactly the same index, hold the same companies, and all charge 0.07% a year.

None of this is a consolation prize: it is the same index and effectively the same portfolio. The live numbers further down this page show the returns land within a rounding error of each other.

The first time it happens it is genuinely confusing: you search VOO, the ticker appears with a live price, and yet the buy button is greyed out or the order bounces back. Nothing is wrong with your account.

The cause is an EU regulation called PRIIPs, in force since January 2018. It requires any fund sold to retail investors, meaning ordinary customers rather than finance professionals, to publish a Key Information Document, or KID: a short standardised sheet describing the fund's risks, costs and possible outcomes. US-listed funds like VOO and SPY do not produce KIDs, so brokers in the UK and EU must block the trade.

The UK kept an equivalent requirement after Brexit and is replacing it with its own version, so the block on US funds remains. It helps to see this for what it is: a paperwork requirement on the fund, not a ban on you.

Vanguard and BlackRock could write KIDs for their US funds, but they have no reason to, because they already sell European versions of the same portfolios. VUSA and VUAG are Vanguard products, and CSPX comes from iShares, BlackRock's ETF brand; the guide to what a UCITS ETF actually is unpacks the wrapper properly.

There is technically an escape hatch, since investors can apply to be reclassified as professional clients, which removes the KID requirement. It also strips away most consumer protections, and the prize is a fund that costs 0.04% a year less. Almost nobody sensible bothers.

For practical purposes, yes. Both track the S&P 500, both hold effectively the same 500 companies in the same weights, and their returns move together almost perfectly, with the tiny gap explained by the fee difference covered below.

VUAG deserves a mention because it is the same Vanguard fund with one behavioural difference: it is accumulating, meaning the dividends the fund collects are reinvested inside it automatically instead of arriving in your account as cash. Long-term investors who do not need the income often prefer that automation, and the guide to accumulating vs distributing ETFs walks through the choice properly.

The comparison pages for VUAG vs VUSA and CSPX vs VUSA chart the funds side by side with live data.

Search data shows something interesting: "CSPX vs VOO" is looked up about 590 times a month in Singapore alone. The reason is that Singapore has no PRIIPs rule, so brokers there often let residents buy VOO directly. For a Singapore investor this is a genuine choice rather than a blocked door.

The case for CSPX rests on where the fund lives. When US companies pay dividends to foreign investors, the US takes a slice off the top before the money leaves the country, a charge called withholding tax.

The dividends are identical, but the tax doubles purely because of the wrapper. The guide to US withholding tax for Singapore investors works through the numbers in detail.

There is a second, less discussed reason. The US can charge estate tax, a tax on what someone owns when they die, on US assets held by non-US investors, and the exposure can start above roughly USD 60,000. VOO counts as a US asset for this purpose, while an Irish fund sits outside that net entirely.

Estate planning interacts with your own country's law, so check your local rules if this matters to you. Put together, this is why the Irish version is the standard choice for most non-US investors even where VOO is freely buyable, and why CSPX is searched so heavily in Singapore.

The word equivalent is doing a lot of work in this article, so here is what our database, with stats refreshed daily, shows. Annualised means the average yearly rate that compounds to the full five-year result.

That is the entire point of this page in a handful of numbers: same index, same result, and equivalent really does mean equivalent.

The same data keeps everyone honest about risk. The worst peak-to-trough fall over the past five years, known as the maximum drawdown, meaning the biggest drop from a high point along the way, was about 24 to 25% for all three funds. Anyone holding an S&P 500 tracker through that stretch watched roughly a quarter of the value disappear before it recovered.

The small gaps between the three, such as VUSA showing about 25% against CSPX's 24%, come from the currency each listing trades in and the exact days measured, not from different holdings. And as always, past figures promise nothing about the future.

Since all three charge the same 0.07% a year, choosing between them comes down to accumulating versus distributing, and to which currency version your broker offers cheaply, not to performance.

Now for the objection everyone raises: VOO charges 0.03% a year and the Irish funds charge 0.07%, so surely VOO wins? Do the arithmetic and the gap is 0.04% a year, which is 4 dollars of extra cost per 10,000 dollars invested, worth having but hardly life-changing. And SPY, the other famous US ticker, charges 0.0945%, which is more than any of the Irish trio.

For investors in countries without a US tax treaty, the withholding difference swamps the fee difference. The S&P 500's dividend yield, the slice of its price that companies pay out as dividends each year, has been roughly 1.2% recently. Paying 15% withholding inside an Irish fund instead of 30% directly keeps roughly an extra 0.18% of your investment each year, which is several times the fee gap, and the saving compounds year after year.

Tax details vary by person and can change, so check your local rules. The quiet takeaway is that everyone quotes the headline fee because it is easy to find, yet for non-US investors the wrapper usually decides more of the outcome than the fee does.

The same question comes up for every famous American ticker, and every answer follows the same logic: find the Irish-domiciled UCITS fund tracking the same index.

If you are torn between owning the whole world and just the S&P 500, the comparison of the FTSE All-World vs the S&P 500 lays out that decision.

The practical fix takes about a minute. On any broker that offers the London Stock Exchange or the big European exchanges, search for CSPX, VUSA or VUAG instead of VOO, and the buy button works normally, exactly as it would for any ordinary share.

For the full walkthrough, the step-by-step guide on how to invest in the S&P 500 covers every click, and the investment calculator shows what a monthly amount could grow into over the years.

None of this is personal advice, but if the only thing standing between you and an S&P 500 fund was a greyed-out VOO button, the door was never actually locked. It just has a different ticker on it.
