What is Adjusted Net Income (ANI) & why is it critical?

Adjusted Net Income (ANI) is the final figure HMRC uses to calculate whether you are entitled to the tax-free Personal Allowance, qualify for Tax-Free Childcare, or are subject to the High Income Child Benefit Charge. It is your gross taxable income minus personal pension contributions (grossed up) and grossed-up Gift Aid donations.

Understanding the 60% (and Scottish 69.5%) Marginal Tax Trap

When your Adjusted Net Income falls between £100,000 and £125,140, your Personal Allowance is reduced by £1 for every £2 earned. This creates a painful 60% effective tax rate inside this zone in England and Wales. In Scotland, the advanced and higher rates push this effective rate to 67.5% (69.5% including National Insurance).

How Salary Sacrifice Pension Contributions shield your income

Under a Salary Sacrifice agreement, you reduce your contractual gross salary in exchange for equivalent pension contributions paid directly by your employer. This lowers your Adjusted Net Income, helping you escape high tax brackets, reclaim lost Personal Allowances, and preserve eligibility for Child Benefit and 30 free hours of childcare.

HMRC Company Car Benefit-in-Kind (BIK) Rates & Private Ownership AMAP Rules

Company Car Benefit-in-Kind (BIK) is subject to Income Tax calculated based on the vehicle's P11D list price multiplied by a percentage determined by its CO2 emissions. For 2025/2026, zero-emission electric vehicles (EVs) are taxed at 3% BIK, rising to 4% for 2026/2027 and 5% for 2027/2028. Plug-in hybrids with electric ranges over 130 miles share these low tiers. Petrol and diesel vehicles can scale up to a maximum cap of 37%. Under standard HMRC rules, if you use a private vehicle for business travel, you can claim Approved Mileage Allowance Payments (AMAP). These are completely tax-free reimbursements of up to 55p per mile for the first 10,000 miles, and 25p per mile thereafter.
