Taking on your first member of staff is exciting. It also comes with a set of legal and financial obligations that catch most first-time employers by surprise.
Here is what you need to do, in order.
Register as an employer with HMRC before your first payday. HMRC will issue you a PAYE reference number. It can take up to 30 days to arrive, so do not leave it late.
Set up payroll software. You need to submit a Full Payment Submission to HMRC on or before every single payday. This is called RTI, Real Time Information. One missed submission means a penalty.
Get employers' liability insurance. Minimum cover of £5 million. This is a legal requirement the moment you take on staff.
Provide a written employment contract from day one. Not within a week. Day one.
Check right to work before they start. You need to see the original documents and keep copies.
Set up auto-enrolment. If your employee is aged 22 to state pension age and earns over £10,000 per year, they must be enrolled into a qualifying pension from their first day. You contribute at least 3% of qualifying earnings. They contribute at least 5%.
Then there are the ongoing costs. Employer National Insurance is 15% on earnings above £5,000 per year. The National Living Wage for workers aged 21 and over is £12.71 per hour from April 2026. PAYE and NI payments go to HMRC by the 22nd of the following month.
If you are eligible, the Employment Allowance reduces your employer National Insurance bill by up to £10,500 per year. Sole directors who are the only employee of their company cannot claim it.
It is a lot, but with the right support, it does not have to feel that way.
