It is one of the most common questions from people who have got past the basics: a global tracker is fine, but a global income trust pays me 4% a year, so is that not simply better? The honest answer is that they are trying to do different jobs, and that most people asking the question want the tracker's job done and the trust's feeling. Here is how to tell which you actually need.
A yield is not a return
The 4% arrives as a dividend, but it does not arrive from nowhere. A company that pays out a pound is a company worth a pound less afterwards, and a trust that pays you 4% from a portfolio growing at 7% in total leaves 3% behind for capital growth. A tracker that pays out less and keeps more has the same 7%. What differs is how much of it lands in your account each year, not how much you are earning.
This matters because a high yield is easy to manufacture. Hold companies that pay out most of what they make, sell a little of the portfolio to top up the dividend, or borrow against it, and the yield goes up while the total return does not. The number to compare is total return after charges, and on that measure a broad global tracker is very hard to beat over long periods. Why one global fund beats the professionals sets out the arithmetic.
What you are paying for
Investment trusts are actively managed and their charges reflect it. Ongoing costs of somewhere between half a percent and one percent are typical; a global tracker is usually between a tenth and a fifth of a percent. Take £50,000 invested for 20 years at 7% before charges. At 0.15% of charges it grows to about £196,003. At 0.9% it grows to about £168,837. The gap, £27,166, is what the trust has to earn back through better decisions just to draw level, before it can be said to be better. What a percentage point does over a working life.
Tax is where the difference gets real
Inside an ISA or a pension none of this matters: dividends and growth are both untaxed, and you should hold either fund there first. Outside a wrapper, a high-yield fund hands you a tax bill every year whether you wanted the cash or not. The dividend allowance for 2026/27 is £500, and above it dividends are taxed at 10.75% for a basic-rate taxpayer, 35.75% at higher rate and 39.35% at additional rate.
Run that £50,000 for 20 years as a 4% yield plus 3% growth, dividends reinvested after tax, against the same 7% with nothing paid out. Untaxed, both reach £201,937. For a higher-rate taxpayer the income version reaches £156,535, a drag of £45,402; for a basic-rate taxpayer £184,024, a drag of £17,913. Growth held in a tracker is only taxed when you sell, with a £3,000 annual exempt amount, and you decide when that is.
The trust pays you 4% and sends the tax bill every year. The tracker keeps the same money working and lets you decide when to be taxed on it.
Two things trusts do that trackers cannot
Trusts can borrow to invest, which the industry calls gearing. It lifts the yield and the return in a rising market and magnifies losses in a falling one. It is a source of extra return that is also a source of extra risk, and the brand promise here is the boring kind of wealth, so treat it as a reason for caution rather than a feature.
Trust shares also trade at their own price, which can sit above or below the value of what the trust holds. Buying at a discount is a small edge; buying at a premium is paying more than a pound for a pound. A tracker fund is priced at exactly what it holds, every day. What actually spreads risk covers why "more moving parts" is not the same as "more diversified".
When the income trust earns its keep
If you are drawing on the money now, an income trust does one thing well: it turns a portfolio into a steady quarterly payment without you having to sell anything, and many have held or raised that payment through decades of bad markets by drawing on reserves. For someone in retirement who values not having to make a selling decision in a downturn, that is a genuine service, and it is worth something.
It is not, however, the only way to take an income. Selling a fixed percentage of a tracker each year does the same job, usually more cheaply, at the cost of having to press the button yourself. The 4% rule, stress-tested for a British portfolio shows what a sustainable withdrawal actually looks like.
So: if you are still building, the tracker, inside an ISA, and let the total return compound untouched. If you are drawing, an income trust is a legitimate choice for the part of your money you want to behave like a pay cheque, provided you know what the charges and the gearing are doing.
