Make the Most of Your Pension: A Client-Friendly Guide 

Pension saving is one of the most tax-efficient ways to build wealth for your retirement. The UK government provides generous tax relief on contributions, but there are strict limits. Exceeding these limits can trigger unexpected tax charges. For higher earners or anyone already drawing from their pension, the rules can be even trickier. 

This guide explains the key pension tax allowances, what happens if you go over them, and strategies to stay on the right side of HMRC. Personal circumstances vary, so we always recommend speaking with a qualified financial adviser before making decisions about your contributions. 

1. Pension Annual Allowance: How Much Can You Save?

The Pension Annual Allowance is the maximum amount you can pay into your pensions each year and still get full tax relief.

  • Standard allowance (2026/27): £60,000
  • Applies across all pension schemes combined (not per scheme)
  • Includes: your contributions, employer contributions, and government tax relief

 

Tip: For defined benefit (final salary) schemes, HMRC looks at the growth in your promised pension benefits, not actual contributions.

Important: You can only get tax relief on contributions up to 100% of your UK earnings (or £3,600 if greater).

2. Tax-Free Pension Lump Sum

One of the most valued features of pensions is the ability to take part of your pot tax-free:

  • Most people can take 25% of their pension pot tax-free
  • Lump sum allowance (2026/27): £268,275


The old Lifetime Allowance was abolished in April 2024, replaced by new allowances. This makes planning larger pensions more complex — specialist advice is strongly recommended.

3. Who Has a Lower Allowance?

a. Higher Earners: The Tapered Annual Allowance

  • Applies if threshold income > £200,000 and adjusted income > £260,000
  • For every £2 above £260,000, your allowance reduces by £1
  • Minimum allowance: £10,000 for incomes above £360,000


Many high earners are caught off guard by this, especially if bonuses or employer contributions are high.

b. Those Who Have Accessed Their Pension: The MPAA

  • Taking taxable withdrawals from a defined contribution pension triggers the Money Purchase Annual Allowance (MPAA)
  • Limits future contributions to £10,000 per year
  • Important: Simply taking your 25% tax-free lump sum does NOT trigger MPAA

4. What Happens If You Go Over Your Allowance?

Exceeding your allowance triggers the Annual Allowance Charge, taxed at your marginal income tax rate.

  • Additional rate taxpayers could pay 45% on the excess
  • You must declare and pay via Self Assessment
  • HMRC may not alert you — it’s your responsibility to check

5. Strategies to Avoid Pension Tax Charges

1. Use Carry Forward

  • Unused allowances from the previous 3 tax years can boost your contributions
  • Rules:
    • Use the current year’s allowance first
    • Must have been in a UK pension scheme during the years you carry forward
    • Cannot exceed 100% of your current earnings


2. Check for Tapered Allowance

  • Review your income before making large contributions
  • Be mindful of salary changes, bonuses, or employer contributions


3. Be Careful When Accessing Your Pension

  • Flexible withdrawals from a defined contribution pension trigger the MPAA
  • Plan carefully if you intend to continue contributing


4. Consider Employer Contributions and Salary Sacrifice

  • Employer contributions count towards your allowance
  • Salary sacrifice can be tax-efficient but must be factored into your total contributions


5. Review Contributions Regularly

  • Circumstances and rules change
  • Regular reviews prevent surprises and help optimise your tax-efficient retirement plan
