Frequently asked questions

What are the statutory employer costs in the UK for 2026/27?
The two statutory employer costs are: employer NI (15% on earnings above £5,000) and employer pension (minimum 3% of qualifying earnings between £6,240 and £50,270 under auto-enrolment). Both are mandatory on top of gross salary for most employees.
How much do employer costs add on top of salary?
Typically 12–18% above gross salary for standard salaries. At £35,000: employer NI £4,500 + pension £863 = £5,363 extra (15.3% above salary). At £50,000: employer NI £6,750 + pension £1,313 = £8,063 extra (16.1% above salary).
What is Employment Allowance and how does it reduce employer costs?
Employment Allowance lets eligible employers offset up to £10,500 of their annual employer NI bill. For a small business with total employer NI below £10,500, this can eliminate the entire NI liability. Single-director companies with no other employees cannot claim.
