The UK Tax Year Ends Soon: 7 Smart Moves to Maximise Your Benefits Before 5 April

The UK tax year runs from 6 April to 5 April. Once it ends, many allowances reset — and if you haven’t used them, you lose them.

Here’s a practical checklist to make sure you’re not leaving money on the table:

1. Max Out Your ISA Allowance (£20,000)

Under the rules set by HM Revenue & Customs, you can invest up to £20,000 per tax year across ISAs:

• Cash ISA

• Stocks & Shares ISA

• Lifetime ISA

• Innovative Finance ISA

  
  

Why it matters:

• All growth is tax-free

• No capital gains tax

• No dividend tax

• No income tax on interest

  
  

If you invest £20,000 today and it compounds at 7% annually for 20 years, that’s over £77,000 completely tax free.

If you don’t use this year’s allowance by 5 April, it’s gone forever.

2. Increase Pension Contributions (Especially via Salary Sacrifice)

Pension contributions are one of the most powerful tax tools in the UK.

You can usually contribute up to:

• £60,000 per year

• Or 100% of your annual earnings (whichever is lower)

  
  

Through Salary Sacrifice:

• You reduce taxable income

• You save income tax

• You save National Insurance

• Your employer may match contributions

  
  

For higher-rate taxpayers (40%+), the effective return on pension contributions can be enormous due to tax relief.

Self-employed? A Self-Invested Personal Pension (SIPP) gives you similar tax benefits.

3. Use Your Lifetime ISA (If You’re Eligible)

If you’re under 40, a Lifetime ISA lets you contribute up to £4,000 per year, and the government adds a 25% bonus.

That’s up to £1,000 per year.

You can use it for:

• First home purchase

• Retirement (after age 60)

  
  

Miss the 5 April deadline, and you miss the bonus for this year.

4. Consider EIS or SEIS Investments

If you’re a higher-income individual or angel investor, the Enterprise Investment Scheme (EIS) and Seed Enterprise Investment Scheme (SEIS) are powerful.

SEIS:

• 50% income tax relief

• Capital gains exemptions (if held 3 years)

EIS:

• 30% income tax relief

• Capital gains deferral

• Loss relief if the investment fails

  
  

These are high-risk investments in early-stage companies — but tax relief significantly reduces downside risk.

Tax-year timing matters here.

5. Use Your Capital Gains Allowance

The annual CGT allowance has been reduced significantly in recent years.

Before 5 April, consider:

• Realising gains up to your allowance

• Bed-and-ISA strategies

• Rebalancing portfolios

  
  

Unused CGT allowance does not carry forward.

6. Check Your Dividend Allowance

The dividend allowance is now only £500.

If you:

• Own shares outside ISAs

• Have a limited company

• Take dividends as income

  
  

Make sure you’ve optimised dividend timing before the tax year resets.

7. Review Salary, Bonuses & Tax Bands

If you're near:

• The £50,270 higher-rate threshold

• The £100,000 personal allowance taper

• The £125,140 additional rate threshold

  
  

Strategic pension contributions before 5 April can:

• Restore lost personal allowance

• Avoid 60% effective tax traps

• Reduce marginal tax exposure

The Big Picture

End-of-tax-year planning isn’t just about “saving tax.”

It’s about:

• Improving net wealth trajectory

• Increasing compounding

• Using structural advantages built into the UK system
