Too Busy to Sort Your Finances? Here's What to Focus On Before the Tax Year Ends

There's a particular kind of financial guilt that arrives around this time of year. It's not loud or dramatic. It's more of a background hum: the vague sense that you meant to sort something, that you're probably leaving money on the table, that you'll definitely get around to it... just not today.

If that sounds familiar, you're not alone. And here's the thing: you've still got time. The 2025/26 tax year ends on 5 April 2026, which as of this week gives you just over six weeks.

Six weeks is genuinely enough. But only if you know where to focus.

What Should You Do Before the Tax Year Ends?

Use your ISA allowance if you haven't already, check whether you can top up your pension before April, and be aware that from 6 April 2026, dividend tax rates are rising. You don't need to do everything. You need to do the things that are relevant to your situation and do them before the deadline.

Why This Year's Deadline Matters More Than Usual

Every year the tax year end matters. But 2026 has a few specifics worth knowing, as well as some of the usual golden rules:

The ISA allowance is £20,000 and it doesn't roll over. As confirmed by HMRC, if you don't use your £20,000 ISA allowance before midnight on 5 April, it's gone. You can't carry it into the next tax year. Many people assume there's some flexibility here. There isn't. Use it or lose it.

Dividend tax rates are rising from 6 April. This one will catch people off guard. As announced in the Autumn 2024 Budget, from the start of the new tax year the income tax rate applied to dividends will increase. If you hold investments outside of an ISA wrapper and receive dividends, moving those investments into a Stocks and Shares ISA before April could make a meaningful difference to your tax position going forward.

The pension annual allowance is £60,000 and some of it may be expiring. As confirmed by HMRC, the standard pension annual allowance for 2025/26 is £60,000. But here's the part people miss: you can carry forward unused allowance from the previous three tax years. The catch is that after 5 April 2026, any unused allowance from 2022/23 expires permanently. If you've been under-contributing to your pension for the past few years, the window to make that up is closing.

Income tax thresholds remain frozen until 2028. As confirmed in successive UK Government Budgets, the income tax personal allowance stays at £12,570 and the higher rate threshold at £50,270, unchanged since 2022 and confirmed to remain so until at least 2028. If your salary has increased at all in the past few years, you're paying more tax than you were, without any change to the headline rates. This makes the tax-efficient wrappers available to you, ISAs and pensions, more valuable as a result.

The Five Things Worth Checking Before 5 April

You don't need to do all of these. You need to work out which ones apply to you.

1. Have you used any of your ISA allowance this year?

Before the mechanics, the coaching question: what is this money actually for?

This matters more than the tax calculation, because without a clear answer you're unlikely to follow through. In my experience, the people who use their ISA allowance consistently aren't the most financially disciplined. They're the ones who have connected their savings to something real: a year off work, school fees, the feeling of not having to worry about what happens next. When the money has a destination, the decisions become easier.

That's the starting point. Once you know what you're building towards, the next question is how long you have to build it. And that answer determines which kind of ISA actually matters.

Cash ISA vs Stocks and Shares ISA: this is where most people stop short

An ISA is a wrapper, not a product. You can hold cash inside it, or you can hold investments. Most people default to a Cash ISA because it feels safe and familiar. But for anything you're building over five years or more, defaulting to cash is likely costing you significantly more than the tax saving is worth.

Here is what the difference looks like with the same £20,000 starting pot:

A Cash ISA at a competitive 4% rate grows to around £29,600 over ten years and £43,800 over twenty. A Stocks and Shares ISA invested in a diversified portfolio, using a 7% annual return as a long-term illustrative figure, grows to approximately £39,300 over ten years. Over twenty years it reaches around £77,400. The gap between saving and investing over twenty years, on the same starting sum, is more than £33,000. Tax-free throughout.

Now add in what happens to that same money held in a standard taxable savings account. For a higher rate taxpayer (40%), the Personal Savings Allowance is just £500 a year. The remaining interest gets taxed, leaving an effective return closer to 3.4%. Over twenty years, that pot reaches around £39,000.

Compare that to a Stocks and Shares ISA at 7%, and the difference is more than £38,000. For an additional rate taxpayer with no Personal Savings Allowance at all, the taxable savings pot over twenty years reaches only around £30,900. The Stocks and Shares ISA advantage over that is close to £46,500.

These figures are illustrative. A 7% investment return is not guaranteed, and real returns will vary depending on what you invest in, when, and for how long. The point is not the precise numbers. The point is the direction of travel: for money you won't need for a decade or more, sitting in cash inside or outside an ISA is unlikely to be the best available choice.

What tends to matter most at this stage is being clear about the timeline. Money you might need in the next two or three years probably does belong in cash. Money earmarked for a goal that's ten or fifteen years away likely belongs in a Stocks and Shares ISA. The coaching conversation is about being honest with yourself about which pot is which, because once you are, the decisions tend to get considerably simpler.

2. Could your pension do with a top-up?

For most people, pension contributions are made automatically each month through payroll. But if you've received a bonus, come into some money, or simply have surplus cash sitting around, making an additional pension contribution before April could be worth exploring.

The tax relief element is the real draw here. A higher rate taxpayer who contributes £10,000 into their pension could effectively receive £4,000 back through their tax return (the basic rate relief is added automatically; the higher rate relief is claimed via self-assessment). For those earning between £100,000 and £125,140, pension contributions can also reduce adjusted net income, potentially recovering some or all of the personal allowance that tapers away at those income levels.

If you've been a member of a pension scheme for the past few years but haven't always contributed up to the annual allowance, you may also have unused allowance from previous tax years available to carry forward. That carry-forward facility closes for the 2022/23 tax year after 5 April 2026.

This is genuinely something worth checking with a professional before making any decisions, as the rules vary depending on your employment type, pension type, and income level.

3. Do you have investments sitting outside a tax-efficient wrapper?

With dividend tax rising from April, there's a question worth asking: are there investments you hold in a general investment account (GIA) that would sit more sensibly inside a Stocks and Shares ISA?

Transferring investments from a GIA to an ISA typically involves selling and rebuying, which has capital gains implications, so this isn't a simple move for everyone. But it's a question worth considering if you regularly receive dividends or have significant unrealised gains building outside of a tax shelter.

4. Have you checked your pension contributions are actually going in at the right rate?

This is a quieter one, but it catches people more often than you'd expect. What I've noticed with clients is that pension contributions get set at a particular percentage of salary early in a career and then quietly sit there, even as the salary grows and the goals change. It's worth logging into your pension provider and confirming the contribution rate is still where you want it to be.

5. Is there anything you've been meaning to sort that keeps getting pushed back?

This is the softer question, but often the most important one. Sometimes the practical steps aren't the actual blocker. The blocker is not having a clear sense of what you're trying to achieve. Some people hold back on ISA contributions because they're not sure whether they're building for the short, medium, or long term. Some people avoid topping up their pension because they're not sure whether they're on track. Some couples avoid the conversation because they don't have a shared picture of what the money is for.

If that's where you are, the next step isn't filling in an ISA form. It's getting clarity on the bigger picture first, so that when you do act, you're acting with intention rather than just ticking a box.

What About Everything Else?

The tax year end brings with it a flurry of content about ISA allowances, pension limits, CGT exemptions, and a dozen other things to theoretically do before April. Most of it isn't wrong, but not all of it is relevant to you.

What tends to matter at this stage is not how many things you know about, but whether you're clear enough on your own situation to know which of those things actually applies to you.

If you're not sure, that's fine. That's exactly what the work is.

"The goal at this time of year isn't to do everything. It's to make sure you haven't quietly lost something that was yours to keep, and that you're heading into the new tax year with some intention, rather than just letting it arrive." - Vig Sivagnanam, The UK Money Coach

The Practical First Step

If you've read this and feel a mild sense of "I should really look at this", that feeling is useful. What tends to help is making that feeling concrete rather than letting it stay vague.

A simple starting point: make a note of which of the five questions above you don't have an answer to. That list of unknowns is your actual to-do list. Everything else can wait.

If working through your specific situation would help, whether that's your ISA position, pension contributions, or just having a clearer sense of where you stand financially, that's exactly what an Insight Session is for. It's a focused, two to three hour session that gives you a full picture of where you are, what to prioritise, and a written plan to follow.

Let's Sort This Out Before April

If you're not sure where to start, or you'd like to talk through whether any of the above applies to your situation, a free Q&A call is the simplest next step. No pressure, no commitment. Just clarity.

The tax year ends 5 April 2026. Six weeks is enough time. But it's not forever.
