Frequently asked questions
What percentage above gross salary is true employment cost?
Typically 16-20% for entry-level, 20-30% for senior. Higher for benefits-rich roles.
Do I have to pay Apprenticeship Levy?
Only if annual pay bill exceeds £3 million. 0.5% of pay bill above threshold.
Can I offset costs by hiring contractors?
Yes but IR35 legislation restricts this where the working relationship is effectively employment. Genuinely independent contractors avoid employer NI + pension.
What's the cheapest employment structure?
Under-21 apprentices are 0% employer NI up to £50,270. Under-25 apprentices similarly.
Do benefits count as taxable pay?
Non-cash benefits (BiK) reported via P11D or payrolled. Employer pays Class 1A NI at 15% on BiK cash equivalent.
What is a P11D — The UK P11D form is submitted annually by employers to HMRC reporting all Benefits in Kind provided to employees. You get a copy showing your total BiK for the tax year. HMRC uses this to adjust your tax code and collect BiK tax.
