How payroll changes when you hire your first employee

Hiring your first employee is an exciting milestone for any business, and the point where payroll becomes a regulated process with fixed steps and deadlines.

Instead of a simple bank transfer, you now have formal employer duties: registering with HMRC, running payroll correctly every pay period, reporting in real time, and meeting workplace pension rules.

Done well, it’s straightforward. Done late or loosely, it can lead to penalties, unhappy staff, and time lost to rework.

 

What actually changes (the essentials)

You become an employer of record.
You must register with HMRC, get your PAYE and Accounts Office references, and use compliant payroll processes from your very first payday.

Payroll runs to a clock.
Each pay cycle requires accurate calculations (tax, NI, student loans, etc.) and an on-or-before Real Time Information submission to HMRC, plus timely payment of liabilities.

Employees get entitlements.
You’ll issue payslips, track holiday and statutory pay, and assess pension eligibility. Even one part-time starter triggers auto-enrolment duties (assessment, communication, and declaration of compliance).

Cash flow looks different.
Beyond salary, budget for employer NI, pension contributions, holiday pay accrual, and occasional statutory payments - costs many first-time employers overlook.

A simple rule of thumb to avoid any pitfalls: set up early, document everything, and automate the deadlines.

 

A quick starter roadmap

1. Before you hire: register as an employer; choose payroll software or appoint a provider; set pay dates and a payroll calendar.
2. Onboarding your first employee: collect starter details and right-to-work documents; set them up in payroll; assess pensions; issue the employment contract.
3. First payday: run payroll; submit RTI on or before payday; issue payslip; set aside PAYE/NI.
4. Month-end/quarterly cadence: pay HMRC; keep records; complete pension communications; review cash-flow impact.
5. After month 3: sanity-check, pension status; adjust processes as you grow.
