Earning Over £260k? The 'Pension Tapering' Trap That Could Slap You with a £15,000 Tax Bill

📉 The Rich Get Squeezed

It is January 2026. You are a successful consultant earning £300,000 a year.
To save tax, you decide to put £60,000 into your SIPP pension, confident that it matches the standard Annual Allowance.

Months later, you receive a dreaded notification on your HMRC app (and the classic brown envelope). It's a tax bill for over £13,000.

Why? Because you fell into the "Tapered Annual Allowance" trap. For high earners, the generous £60,000 limit evaporates. It can shrink all the way down to a measly £10,000. If you contribute more than your personal tapered limit, you pay tax on the excess at your marginal rate (45%).

The rules are notoriously complex, involving two different definitions of income to catch you out.

Earning Over £260k?

Are You Tapered? The 2 Tests

You are only affected if you breach BOTH of these thresholds in the 2025/26 tax year.

• 1. Threshold Income > £200,000: This is your taxable income (salary, bonus, rental, dividends) MINUS your personal pension contributions.
• 2. Adjusted Income > £260,000: This is your taxable income PLUS any employer pension contributions. (This is the "hidden" figure that catches people).

* Example: Salary £240k + Bonus £10k + Employer Pension Contribution £20k = Adjusted Income £270k. You are above £260k, so you are tapered.

How Much Allowance Do You Lose?

For every £2 your Adjusted Income goes over £260,000, your Annual Allowance drops by £1.

• Income £260k → Allowance £60,000 (Full)
• Income £300k → Allowance £40,000
• Income £360k+ → Allowance £10,000 (Minimum Floor)

The Solution (Carry Forward)

Did you use your full allowance in the last 3 tax years? Probably not.
You can carry forward unused allowances from the previous 3 years to boost your limit this year.

Even if you are tapered to £10k this year, if you have £40k unused from 3 years ago, your total limit becomes £50k. This allows you to make a significant contribution without triggering the 45% tax charge.
Requirement: You must have been a member of a UK registered pension scheme during those previous years to use this.

🛡️ Chief Editor’s Verdict

Don't guess. Calculate.

1. The "Employer" Trap: Most high earners forget to add their employer's pension contribution back into their income to calculate "Adjusted Income." This is the #1 cause of unexpected tax bills.
2. The "Scheme Pays" Deadline: If you do trigger a tax charge over £2,000, you can force your pension scheme to pay the tax from your pot ("Scheme Pays"). However, strict deadlines apply (usually July 31st of the following year). Don't miss it, or you pay cash.

A £15,000 tax bill is a painful lesson. Use Carry Forward wisely.
