The start of a new tax year is one of the best moments to pause, take stock, and make sure your finances are still working as hard as possible for you.

In the latest Retire Well podcast episode, Matthew and Joe explore what hasn’t changed as much as what has — and why that still matters. With allowances largely frozen, tax efficiency is more about good planning than reacting to last‑minute surprises.


Here’s a practical breakdown of the key points to consider as we move into the new tax year.

1. The Big Picture: Nothing New… But That Still Matters

Despite rumours ahead of the Spring Statement, there were no major pension or ISA shake‑ups announced. Notably:

  • No reduction in pension tax‑free cash
  • No reduction in the overall £20,000 ISA allowance

2. Personal Allowances: Frozen, But More Important Than Ever

Most income tax thresholds remain frozen, which effectively acts as a stealth tax as wages, pensions, and interest creep upward.

Key income thresholds to remember:

  • Personal Allowance: £12,570
  • Basic Rate Band: up to £50,270 (20%)
  • Higher Rate Band: £50,270–£125,140 (40%)
  • Additional Rate: above £125,140 (45%)

If you’re approaching or already in retirement, aiming to take at least £12,570 of taxable income (for example from a pension) can make sense. Any additional income can often be taken from:

  • Pension tax‑free cash
  • ISAs
  • Cash savings

This kind of coordination can significantly reduce the tax you pay.

3. The £100,000 Tax Trap (and How to Escape It)

If your income exceeds £100,000, you begin losing £1 of personal allowance for every £2 earned above that level. This creates an effective 60% tax rate between £100,000 and £125,140.

A powerful planning tool here is pension contributions:

  • Contributions reduce your adjusted income
  • You regain lost personal allowance
  • You receive full tax relief

For many people, pension funding isn’t just about retirement — it’s about avoiding unnecessary tax right now.

4. Pension Contributions: Think Monthly, Not Last Minute

One common mistake is waiting until March and then trying to make a large pension contribution in one go.

Spreading contributions monthly across the year has benefits:

  • Easier psychologically than a large lump sum
  • Reduces investment timing risk
  • Helps smooth market ups and downs

Salary sacrifice arrangements can be especially valuable this tax year, even more so if your employer shares their National Insurance savings with you.

5. Savings Interest and Tax Codes: Check the Small Print

With higher interest rates, more savers are now exceeding their Personal Savings Allowance:

  • £1,000 for basic‑rate taxpayers
  • £500 for higher‑rate taxpayers
  • Up to £5,000 extra for non‑taxpayers via the starting rate for savings

Banks now report interest directly to HMRC, which means your tax code may include “untaxed interest” adjustments.

It’s well worth reviewing your tax code at the start of the year to make sure it reflects reality — especially if you’ve had large cash balances temporarily.

6. Capital Gains and Dividends: Tighter Allowances

Allowances remain low:

  • Capital Gains Tax Annual Exemption: £3,000
  • Dividend Allowance: £500

This doesn’t limit investment options, but it does reinforce the importance of tax wrappers:

  • ISAs for tax‑free growth and income
  • Pensions for long‑term planning
  • Other tax‑efficient structures where appropriate

Using your ISA allowance early in the tax year is often sensible — it’s strictly use it or lose it.

7. Gifting and Estate Planning: Don’t Forget the Allowances

A new tax year is also a good time to review estate planning:

  • £3,000 annual gifting allowance (can be carried forward one year)
  • Wedding gifts:
    • £5,000 to children
    • £2,500 to grandchildren
    • £1,000 to others
  • Gifts out of surplus income (must be properly documented)

Good records are essential, especially as many of these exemptions are assessed only when your estate is settled.

8. State Pension: Getting Close to the Tax Line

The full State Pension has increased to just under £11,973 per year.

That means it’s edging close to — and in some cases exceeding — the personal allowance. If the State Pension is your only income, it’s paid gross, but you may still need to complete a tax return once it exceeds the allowance.

If you draw income flexibly from other sources, this increase may mean it’s time to adjust what you take elsewhere.

Final Thought: Plan Early, Not in a Panic

The biggest takeaway from the discussion is simple:

Good tax planning isn’t about last‑minute decisions — it’s about forward thinking.

At the start of the tax year:

  • Review your income sources
  • Check your allowances
  • Look at pensions, ISAs, and savings together
  • Make a plan that lasts the full 12 months

That way, you’re not scrambling next March — and you’re far more likely to keep more of what you earn.
