Large employer: add the Apprenticeship Levy
If your annual UK pay bill is over £3 million, HMRC charges a 0.5% Apprenticeship Levy on the whole payroll (minus a £15,000 allowance). For a headcount of 100 staff each on £35,000 (total payroll £3,500,000), that works out to about £25 per employee per year on top of the employer NI and pension. Large employers are also typically not eligible for the £10,500 Employment Allowance.

Frequently asked questions
What is the true cost of a £35,000 salary to a UK employer?
For 2025-26, a £35,000 salary costs a small UK employer about £35,863 per year, rising to £35,863 in 2026-27. That includes £4,500 in Class 1 employer NI (15% over the £5,000 secondary threshold), £863 in minimum 3% auto-enrolment pension on qualifying earnings (£6,240–£50,270), offset by £4,500 of the £10,500 Employment Allowance if eligible.
How is employer National Insurance calculated on £35,000?
HMRC Class 1 secondary (employer) NI is 15% on earnings above the £5,000 secondary threshold (both 2025-26 and 2026-27). For £35,000, that's 15% × £30,000 = £4,500 per year before any Employment Allowance offset.
Does every employer pay the Apprenticeship Levy on £35,000?
No — only employers with an annual pay bill over £3 million pay the 0.5% Apprenticeship Levy, and the first £15,000 is offset by the Levy Allowance. A small business paying one person £35,000 is well below the threshold and pays nothing. A large employer with 100+ staff on £35,000 would pay roughly £25 per employee per year.
Can Employment Allowance reduce the cost of hiring on £35,000?
Yes — eligible small employers can offset up to £10,500 of Class 1 employer NI per tax year (2025-26 and 2026-27). On a £35,000 salary that offset is worth £4,500. Employment Allowance is only available to businesses whose employer NI bill in the previous tax year was under £100,000.
What does the true cost exclude?
This calculation covers the mandatory HMRC on-costs: employer NI, minimum auto-enrolment pension, and Apprenticeship Levy. It excludes statutory sick pay, maternity/paternity pay, holiday pay (20 days + 8 bank holidays), training, equipment, recruitment agency fees, and any discretionary benefits like private medical insurance or bonuses.
