ISA Basics

A child born today has one thing no adult can buy back: time. The simplest way to turn it into a tax-free sum.

Junior ISA. Lifetime ISA. Stocks and Shares ISA. They’re not rivals, they’re family: five accounts, each built for a different job. Here’s which one fits yours.

What a Stocks and Shares ISA actually is, how the tax-free wrapper works, and why it matters.

The most generous ISA going, and the most punishing if you get it wrong. The bonus, the penalty, and the 2028 change.

The Budget changed the cash ISA rules, just not yet. What was announced, when it bites, and what it means.

If it promises to make you rich quickly and effortlessly, it is lying. How to spot it before it costs you.

They sound like the same thing. They are not. Here is how to tell which job you are doing.

Two people, same investment, same years, very different results. The reason is the one part of returns you control.

The government plans to replace the Lifetime ISA with a First-Time Buyer ISA. Here is what is proposed, and what it means if you already have one.

The consultation to replace the Lifetime ISA closed on 18 August 2026. Where the reform stands now, and what it means for your Lifetime ISA in the meantime.

You put money in, you get a bit more back. What happens when that bit more starts earning its own is compounding.

Not men in suits shouting, not a coin that turned £500 into £50,000. What investing actually is, noise stripped out.

From April 2027 the cash you leave sitting in a stocks and shares ISA gets a flat 22% charge on its interest. Here's what the rule does, and what it doesn't.

A tax-free allowance every year, gone at midnight on 5 April if you do not use it. Here is how it works.

Returns are a guess. The cost is contractual. What a fraction of 1% really takes over thirty years, and the layers most people never add up.

Not a yacht or retirement at 35. The more useful version: the point where work becomes a choice.

Everyone obsesses over returns. The number that matters more early on is the one you fully control: what you put in.

Opening the account takes ten minutes. The decisions around it, the platform, the charges, flexible or not, and whether to transfer, are what shape what you keep.

HMRC counted 5,070 of them. Not one got there in cash, and most of the million isn’t money they paid in.

Most people invest in the wrong order, and it costs them more than they realise. Here is the sequence I follow, and why each step earns its place.

The honest maths of a seven-figure ISA: how much a month, how many years, and why most of the million is growth rather than the money you put in.

The one rule that protects your tax-free status when you move an ISA, plus how transfers really work: your allowance, partial moves, switching type, and timescales.

The three aren't rival products, they're a spectrum of concentration: the whole market, a theme like AI or tech, or a single company. What each one asks of you.

The market gives you a number every second it is open. Almost none of it is information. Why the horizon you measure by matters more than almost anything else you choose.

Everyone starts with the pension and stops there. Here's what the ISA, LISA and JISA do that a pension can't, and the half of the plan most people skip.

Holding lots of things is not the same as being diversified. What actually spreads risk, the home-bias trap, and where diversification stops.

Reinvested dividends do a large share of the work, and it is easy to overlook. How the compounding actually happens, and why an ISA lets you keep all of it.

Tax free for your whole life, and part of your estate the moment it ends. Plus the rule most people have never heard of.

You can take the money out whenever you like. Getting the allowance back is the part nobody mentions.
