Tax Year End 2026: What You Should Be Thinking About Before 5 April

As the end of the tax year approaches, it’s easy to feel pressured by deadlines and last‑minute financial decisions. But as Matthew and Joe explain in their latest Retire Well episode, year‑end planning isn’t about rushing. It’s about awareness, preparation, and taking small steps that build long‑term financial resilience.

Whether you’re still growing your wealth or already drawing from it in retirement, understanding how allowances work (and how to use them purposefully) can make a meaningful difference over time.

‍

1. Start with Understanding Your Income and Tax Position

One of the simplest but most overlooked steps is knowing exactly what you’ve earned in the tax year. Many people know what reaches their bank account each month, but fewer can clearly identify:

• Total earnings

• Bonuses

• Benefits in kind

• Their effective tax band

Checking your government gateway account helps establish this baseline. It also highlights whether you’re approaching key thresholds:

• £50,270 (basic rate limit)

• £100,000 (loss of personal allowance)

• £125,140 (additional rate)

Crossing £100,000 is particularly significant due to the rapid tapering of the personal allowance.

For many people, this is where active planning, especially through pension contributions, can make a major difference.

2. Pension Contributions: A Powerful and Underused Planning Tool

Pensions remain one of the most tax‑efficient ways to save, reduce taxable income, and prepare for retirement.

Key rules to keep in mind:

• The standard annual allowance is £60,000.

• If you need to contribute above £60,000, carry forward from the previous three tax years can help—often useful for business owners or those receiving redundancy payments.

• High earners may face a tapered allowance as low as £10,000.

• If you've already taken taxable pension income, the Money Purchase Annual Allowance restricts you to contributing £10,000 per year with no carry forward.

“It’s that joined‑up thinking, planning ahead rather than scrambling at the end of March or early April.” — Matthew

This is especially relevant for anyone close to key tax thresholds.

3. ISA: Simple, Flexible and Often Underestimated

Your ISA allowance is straightforward:

Use up to £20,000 per tax year or lose it.

Cash ISAs and Stocks & Shares ISAs are both eligible, and many providers offer flexible ISAs, allowing you to withdraw money and put it back in the same tax year without affecting your allowance.

This can be particularly useful if:

• You've taken withdrawals during the year

• You’ve recently received a lump sum you want to shelter

• You want a simple option without making immediate investment decisions

With dividend and capital gains tax allowances shrinking, ISAs offer increasingly important tax protection.

4. General Investment Accounts and Capital Gains Awareness

For those holding investments outside a wrapper, the General Investment Account (GIA) can serve as a flexible short‑to‑medium‑term pot. But with the capital gains tax allowance now just £3,000, managing gains and losses becomes essential.

Remember:

• Losses in a GIA can be offset against gains

• Losses inside an ISA cannot

• Transfers between spouses are tax‑free, helping maximise allowances across a household

Many investors now use GIAs as “holding accounts” before gradually moving money into ISAs or pensions each year.

5. Don’t Forget National Insurance and State Pension Planning

If you’re approaching state pension age, topping up missing National Insurance (NI) years can offer excellent long‑term value.

You can:

• Check your NI record online

• Identify missing or partial years

• Use Class 3 contributions to fill gaps at around £923 per year

Doing so can add £342 per year to your future state pension, often paying for itself within three years.

This is especially important as you near retirement and have fewer working years remaining to naturally fill gaps.

6. Shifting the Mindset: From Accumulation to Decumulation

Once you begin drawing from pensions, ISAs, and investments, tax planning takes on a different focus. It’s now about using your allowances efficiently and avoiding unnecessary tax.

Key considerations include:

• Making use of your personal allowance before state pension begins

• Drawing income in a way that keeps you within the basic rate band where possible

• Splitting withdrawals across tax years

• Coordinating strategy between spouses

• Using various tax wrappers to manage income sources

Large withdrawals for home improvements, cars, or travel should ideally be spread across years to avoid being pushed into higher tax bands.

7. Estate Planning: An Annual Check-In

The end of the tax year is a natural time to reassess estate‑related documents and decisions, including:

• Wills

• Pension nominations

• Expression of wish forms

• Gifting plans

Inheritance tax (IHT) thresholds have been frozen for years, while property and pension values have risen—pushing more households into the IHT net.

Many people assume estate planning is only for the wealthy, but the freeze on the nil‑rate band and property inflation mean this is no longer true.

Gifting allowances to remember:

• £3,000 annual exemption (can carry forward one year)

• £250 small gifts to any number of individuals

• Gifts out of surplus income—highly effective and often under‑utilised

These can form part of thoughtful, long‑term estate planning rather than reactive, last‑minute action.

Final Thoughts

Tax year end isn’t about complicated strategies or frantic decisions. It’s about:

• Understanding your position

• Making purposeful use of allowances

• Reducing avoidable tax

• Building financial flexibility for the future

Small, consistent decisions repeated year after year create powerful long‑term results.
