How to compare income ETFs without yield traps

This is a decision framework, not the comparison tool

This page is an editorial framework — it teaches you the three income-ETF buckets (dividend, covered-call, overlay) that should never be ranked together. It is not the interactive comparison tool.

The three income buckets to keep separate

Questions to ask before buying an income ETF

Why a high headline yield can be a trap

A yield is just a fraction: income divided by price. That means a number can climb for healthy reasons or for unhealthy ones, and the headline figure alone never tells you which.

Here are the most common ways a tempting yield turns out to be a trap:

• Yield from a falling price. If a fund pays the same income but its price has dropped 30%, its quoted yield jumps — mechanically, not because anything got better. A rising yield is sometimes the market warning you that the underlying holdings are in trouble. Always check what the price did, not just the percentage.
• Return of capital dressed up as income. Some products pay out a distribution that is partly just your own money handed back, or partly capital rather than genuine income. The payout looks generous while the capital base quietly shrinks. A smooth, high distribution that coincides with a sagging share price deserves real scrutiny.
• Concentration risk. A high-yield equity screen can pile into one or two sectors — historically things like tobacco, utilities, financials or energy. You may end up with far less diversification than a broad index, and a payout that depends on a handful of companies not cutting dividends.
• Covered-call ETFs capping the upside. Option-overlay (“covered call”) funds generate a chunky distribution by selling away some of the fund's potential price gains. In a flat or gently rising market that can look wonderful. In a strong bull market the fund can badly lag a plain index, because the upside it sold is exactly the upside that drove the market. The income is real, but it is paid for out of future growth.

What to compare instead of yield

Once you stop ranking funds by the payout line, a cleaner checklist emerges. These are the things that actually separate a durable income holding from a yield trap.

A practical way to assess whether income is sustainable is to look at whether the distribution is broadly covered by the genuine income the underlying assets produce — dividends from the shares, coupons from the bonds — rather than topped up from capital. If a fund consistently pays out more than its holdings earn, that gap has to come from somewhere, and usually it comes from the capital base.

The UK tax angle on investment income

How your income is taxed can quietly change which fund, and which account, makes sense. The headline yield is a pre-tax number; what you keep depends on the wrapper.

• The Dividend Allowance is £500 for 2026/27. Dividend income up to that amount is tax-free; above it, dividends are taxed at the dividend rates according to your tax band. Equity income funds held outside a tax wrapper can use this allowance up quickly.
• Interest is taxed differently from dividends. The income from a bond-based income ETF is generally treated as interest (covered by the Personal Savings Allowance, where available), whereas an equity income ETF pays dividends. The same headline yield can land in a different tax box depending on what the fund holds.
• Holding income funds in an ISA removes UK tax on the distributions. Inside a Stocks and Shares ISA (£20,000 annual allowance for 2026/27), dividends and interest are free of UK income tax and gains are free of CGT — so the £500 dividend allowance becomes irrelevant for that money. For income investors, the ISA (and pension) wrapper is often the first decision, before the choice of fund.
• “Income” units are still taxed even if reinvested. With accumulation units, the rolled-up income can still be taxable in a General Investment Account. The tax does not disappear just because no cash reached your bank account.

This is educational information, not personal tax advice. The right combination of fund type and account depends on your own income, allowances and objectives — and on whether you genuinely need spendable income now or are simply chasing a number on a screen.
