Tax & Planning for Higher Earners

1. The 60% Tax Trap (£100k–£125,140)

If you earn between £100,000 and £125,140, you lose £1 of personal allowance for every £2 earned above £100k. This creates an effective marginal tax rate of 60% on income in this band.

            How it works: Your £12,570 personal allowance is gradually withdrawn. On the £25,140 between £100k and £125,140, you pay 40% income tax PLUS lose allowance worth 20% — totalling 60% effective tax on every extra pound.
          

The pension solution

Pension contributions reduce your "adjusted net income." If you earn £110,000 and contribute £10,000 to your pension, your adjusted net income drops to £100,000 — restoring your full personal allowance.

Example: You earn £115,000.

Without pension contributions: you lose £7,500 of personal allowance, paying an extra £3,000 in tax
Contribute £15,000 to your pension: adjusted income drops to £100,000
You restore the full £12,570 allowance AND get 40% tax relief on the contribution
Net cost of £15,000 pension contribution: approximately £6,000

💡 If you're in this band, pension contributions are extraordinarily efficient. Every £1 you contribute effectively costs you just 40p.

2. The Child Benefit High Income Charge

If you or your partner earns over £60,000, you begin to lose Child Benefit through the High Income Child Benefit Charge (HICBC). At £80,000, you lose it entirely.

            The pension solution: Pension contributions reduce your adjusted net income. By contributing enough to bring it below £60,000, you can retain your full Child Benefit entitlement.
          

Example

Scenario: You earn £75,000 and have 2 children. Child Benefit is worth £2,212/year.

At £75,000, you'd repay 75% of Child Benefit = £1,659/year charge
Contribute £15,000 to your pension: adjusted net income drops to £60,000
You retain the full £2,212 AND get 40% tax relief on the £15,000 (£6,000 back)
Total benefit: £2,212 + £6,000 = £8,212 — for a £15,000 pension contribution

3. Salary Sacrifice

Salary sacrifice is an arrangement where you agree to a lower salary in exchange for your employer making pension contributions on your behalf. The key benefit: you save National Insurance (NI) as well as income tax.

How it works

1

You agree to reduce your salary

e.g. from £80,000 to £75,000

2

Your employer pays the £5,000 directly into your pension

This is an employer contribution, not yours

3

You save NI (8%) and income tax (40%)

On a £5,000 sacrifice: save £400 NI + £2,000 tax = £2,400 saved

💡 Bonus: Your employer also saves 13.8% employer NI on the sacrificed amount. Many employers share this saving with you by increasing the pension contribution. Ask your HR team if this applies.

Things to consider

Your reduced salary is used for mortgage affordability calculations
It may affect maternity/paternity pay if based on salary
Life insurance and other benefits linked to salary may reduce
You cannot sacrifice below the National Minimum Wage

4. ISA Strategy — Pension vs ISA

Both pensions and ISAs offer tax-efficient growth. The right balance depends on your age, income, and when you need access to the money.

	Pension (SIPP)	Stocks & Shares ISA
Tax relief on contributions	✅ Yes (40%/45%)	❌ No
Tax-free growth	✅ Yes	✅ Yes
Tax on withdrawal	⚠️ Yes (income tax)	✅ No
25% tax-free lump sum	✅ Yes (up to £268,275)	N/A
Access before 57	❌ No (from 2028)	✅ Yes
Annual limit	£60,000	£20,000
Inheritance tax	✅ Outside estate	⚠️ In estate

💡 General rule: Maximise pension first (especially if employer matches), then use ISA for flexibility. If you're subject to the tapered annual allowance, ISA may be more efficient above the tapered limit.

5. Zakat on Investments & Pensions

Zakat is an obligation on wealth above the nisab threshold. For Muslim professionals with investments and pensions, the key questions are: what's zakatable, and how do you calculate it?

General principles

Cash savings: Zakatable at 2.5% of the balance above nisab on your Zakat anniversary
Stocks & shares ISA: Zakatable — calculate 2.5% of the current market value
Pension pot (before retirement): Scholars differ. Many hold that pensions are not zakatable until you can access them (age 57). Others say Zakat is due on the accessible portion. Consult your local scholar.
Property (primary home): Not zakatable
Buy-to-let property: Scholars differ — some say Zakat on net rental income, others on market value minus debt. Seek guidance.

💡 Practical tip: Set a fixed Zakat anniversary date (many use Ramadan). On that date, total your zakatable assets, subtract debts, and pay 2.5% on the net amount above nisab (approximately £4,500 in 2025/26 based on silver value).

Zakat-friendly approach to investing

Some investors prefer accumulating funds (which reinvest dividends) over distributing funds, as it simplifies Zakat calculation — you only need to value the holding once per year rather than tracking income throughout the year.
