How to Run Payroll with Payslips & Statutory Deductions
Run a payroll cycle end to end — pension auto-enrolment, student loan, statutory pay — and generate payslips that post automatically to accounting.
Before you start
- Employees have pay details set (pay type, rate/salary, pay frequency)
- Pension and student loan settings are configured on each employee profile
- Your payroll country bands are set (see How to Set Up Multi-Country Payroll)
Step 1 — Create a payroll run
- Go to HCM → Payroll
- Click + New Payroll Run
- Choose the pay period and the employees to include
- Plenix pulls hours from timesheets (for hourly staff) and salaries (for salaried staff)
Step 2 — Review calculations
For each employee, the run calculates:
| Line | Source |
|---|---|
| Gross pay | Salary or hours × rate |
| Income tax | Country tax bands |
| National insurance | Country NI bands |
| Pension | Auto-enrolment rate, unless the employee has opted out |
| Student loan | Based on the employee's plan (Plan 1/2/4/postgrad) |
| Statutory pay | SSP / SMP where applicable |
| Net pay | Gross minus all deductions |
Adjust any line before finalising if needed.
Step 3 — Generate payslips
- Click Finalise Run
- Plenix generates a payslip for each employee showing gross, every deduction, and net
- Employees can view their payslip from their self-serve HCM page
Step 4 — Post to accounting
On finalisation, Plenix creates the payroll journal automatically:
- Wages expense
- Tax / NI / pension liabilities
- Net pay owed
Find it under Accounting → Journal Entries, linked back to the payroll run.
Step 5 — Accounting pays employees
Processing the run sends it to Accounting → Payroll Payments as Awaiting payment. Accounting downloads a CSV or BACS Standard 18 bank file, sends the payments and clicks Mark as paid. That clears the net pay owed and takes the money from the bank account. See Pay Payroll and Claims.
Tips
- Run a draft first to preview figures before finalising
- Pension opt-outs and student loan plans live on each employee's payroll profile
- Statutory pay (SSP/SMP) is calculated automatically when leave of the right type is recorded
