Section 3
Personal allowance trap exposure
You are in the personal allowance taper zone
In the UK, everyone gets a tax-free allowance of £12,570. But once your income goes above £100,000, HMRC gradually takes that allowance away. Based on your inputs, your estimated income is £██,███ — placing you £██,███ into the taper zone. Your tax-free allowance has shrunk from £12,570 to just £█,███. You are effectively paying around 60p in tax for every extra £1 earned in this range.
£100,000£125,140
⭐ Pro tip

Most people only think about the 40% tax saving on pension contributions. But if contributing brings your adjusted net income below £100,000, you also recover your personal allowance — worth an additional estimated £5,028 in tax savings. A £██,███ pension contribution in your situation could be worth up to £█,███ in total estimated tax savings — not just the 40% many people assume.

Section 5
Questions to ask your accountant

Based on your inputs, these are the specific questions worth raising at your next accountant or HR meeting. Walking in with these questions saves time and gets better outcomes.

1What is my adjusted net income for 2025/26 including all income sources — and am I correctly in or approaching the personal allowance taper zone?
2What pension contribution would bring my adjusted net income below £100,000 — and does my employer offer salary sacrifice?
3Am I claiming full 40% higher rate pension relief on my Self Assessment return, or only the 20% applied automatically?
4Would my employer pass back some of their National Insurance saving if I increased my salary sacrifice pension contribution?
5Should I be sacrificing my bonus into my pension this year given my income level and trap position?
6Are there Gift Aid donations I could make before April 5th to further reduce my adjusted net income?
7Is my Self Assessment tax return correctly filed for 2024/25 — and am I registered given my income exceeds £100,000?

What to do next
Check your NI record and State Pension forecast
Log into your HMRC Personal Tax Account at gov.uk/personal-tax-account. Under National Insurance you can see your qualifying years, any gaps, and your current State Pension forecast.
Speak to your HR or payroll team about pension options
Ask whether salary sacrifice is available, whether your employer passes back employer NI savings, and what your current pension arrangement type is.
Consider speaking to a qualified tax adviser
Given your income level and trap exposure, a one-off conversation with a qualified accountant or tax adviser could be valuable. Use the questions in Section 5 as your starting point.
