It's not a headline rate — it's the real arithmetic of the taper under Income Tax Act 2007 s35."},{"error_id":2,"ai_says":"ChatGPT says: Earning more always means more take-home pay","correct":"Reality: Between £100,000 and £125,140 earning an extra £1 gives you only 40p. At some NI + student loan + child benefit clawback combinations, the effective marginal rate can exceed 70%. A £5,000 bonus in this band nets approximately £2,000 after all deductions."},{"error_id":3,"ai_says":"ChatGPT says: Pension contributions just defer tax — you pay it later","correct":"Reality: A pension contribution that restores your personal allowance doesn't just defer the allowance withdrawal cost — it ELIMINATES it. The £12,570 that would never have been received tax-free gets restored. This saves up to £5,028 in tax that would otherwise never come back. That's in addition to the ordinary pension tax relief on the contribution itself."},{"error_id":4,"ai_says":"ChatGPT says: My employer handles my tax so this is not my problem","correct":"Reality: PAYE handles income tax on employment income based on your tax code. It does NOT model your TOTAL adjusted net income including rental, self-employment, dividends, or side-consulting. The 60% trap only surfaces on self-assessment — by which time the allowance is already lost for that year and cannot be retrospectively restored."}],"faq":[{"id":1,"question":"What is the UK 60% tax trap?","answer":"The 60% tax trap is the effective marginal tax rate faced by UK earners with adjusted net income between £100,000 and £125,140. The personal allowance of £12,570 is withdrawn at £1 for every £2 earned above £100,000 — fully gone at £125,140. Combined with 40% higher-rate income tax, the effective marginal rate on earnings in this band is 60%."},{"id":2,"question":"How does the personal allowance taper work?","answer":"For every £2 of adjusted net income above £100,000, £1 of personal allowance is withdrawn. At £100,000 you have the full £12,570 allowance. At £110,000 you have £7,570. At £125,140 you have zero. The taper is automatic under Income Tax Act 2007 section 35. Adjusted net income includes employment, self-employment, rental, savings, and dividends — minus deductions like gross pension contributions and Gift Aid."},{"id":3,"question":"Can pension contributions really save me 60% in tax?","answer":"Yes. A pension contribution that brings adjusted net income below £100,000 achieves two things simultaneously: (1) the contribution itself gets higher-rate pension relief (40% for higher-rate taxpayers), and (2) the personal allowance is restored, saving the tax that would have been paid on that £12,570 at the higher rate. Combined effective saving can approach 60% of the contribution amount."},{"id":4,"question":"What is salary sacrifice and why is it better than personal pension contributions?","answer":"Salary sacrifice is an employer-facilitated arrangement where part of your salary is redirected to pension BEFORE tax or NI is deducted. Unlike personal pension contributions (which save only income tax), salary sacrifice also saves employee NI (8-13% depending on band) and employer NI (typically 13.8% — often reinvested into the pension). Combined saving on a £15,000 salary sacrifice at this income level can exceed 60% of the contribution amount."},{"id":5,"question":"What is adjusted net income?","answer":"Adjusted net income is the income figure used to calculate the personal allowance taper. It includes all taxable income from employment, self-employment, rental, savings, and dividends. It is REDUCED by gross pension contributions (including employer and personal), Gift Aid donations (grossed up), and certain other reliefs. It is NOT reduced by ordinary deductible expenses or capital losses. HMRC's calculator on gov.uk provides the exact definition."},{"id":6,"question":"Does the 60% trap apply if I receive dividends instead of salary?","answer":"Yes, in effect. Dividend income is subject to its own dividend tax rates (8.75% basic, 33.75% higher, 39.35% additional rate) but dividends still count toward adjusted net income for personal allowance taper purposes. Company directors taking £95k salary + £40k dividends can easily cross £100k adjusted net income and lose allowance — even though their marginal tax on the dividends themselves is 33.75%."},{"id":7,"question":"What about the child benefit tax charge?","answer":"The High Income Child Benefit Charge (HICBC) is a separate clawback that starts at £60,000 and fully claws back child benefit at £80,000 (thresholds changed in April 2024). This creates an additional effective tax rate stack — in the £60k-£80k band you can face a combined 50%+ effective rate depending on number of children. Above £100k you stack the 60% allowance taper on top. Can mean effective rates above 65% for families with multiple children."},{"id":8,"question":"Is there any way HMRC shows this on my payslip or tax code?","answer":"No, not directly. The personal allowance taper is applied at self-assessment or via adjusted tax code if HMRC has income projection data. Most taxpayers in the £100k-£125k band discover the 60% trap only when they file their tax return — often nine to twelve months after the year ends. By then the allowance for that year is permanently lost and cannot be retrospectively restored."}],"sources":[{"title":"HMRC — Income Tax rates and Personal Allowances","url":"https://www.gov.uk/income-tax-rates"},{"title":"HMRC — Personal Allowance and income over £100,000","url":"https://www.gov.uk/income-tax-rates/income-over-100000"},{"title":"HMRC — Tax on your private pension contributions (tax relief)","url":"https://www.gov.uk/tax-on-your-private-pension"},{"title":"Income Tax Act 2007 — section 35 (Personal allowance)","url":"https://www.legislation.gov.uk/ukpga/2007/3/section/35"},{"title":"Machine-readable JSON rules","url":"/api/rules/allowance-sniper"}],"products":{"tier1":{"name":"Your Allowance Audit Pack","price":67,"currency":"GBP","description":"Your exact 60% trap exposure and the pension contribution that escapes it","url":"https://taxchecknow.com/uk/check/allowance-sniper/success/assess"},"tier2":{"name":"Your 60% Tax Escape Plan","price":147,"currency":"GBP","description":"Full escape plan: pension optimisation, salary sacrifice, bonus timing — written for your situation","url":"https://taxchecknow.com/uk/check/allowance-sniper/success/plan"}},"monitor_urls":["https://www.gov.uk/income-tax-rates/income-over-100000"],"canonical":"https://taxchecknow.com/uk/check/allowance-sniper","api_endpoint":"/api/rules/allowance-sniper","generated_at":"2026-04-23T01:37:28.723Z"}
