The Moonworkers payroll software is a web application available at payroll.moonworkers.co.uk. It is designed for UK employers who want to run payroll for their employees without using a payroll bureau or external accountant.
RTI submissions to HMRC
Every time you run a payroll, the software automatically sends a Full Payment Submission (FPS) to HMRC. At the end of each tax month, it sends an Employer Payment Summary (EPS) where required. These submissions are made without any manual action from you. Moonworkers is listed as HMRC-recognised software for RTI.
PAYE, National Insurance, and pensions
The software calculates Income Tax under PAYE for all employee tax codes, including cumulative and non-cumulative codes. It calculates employee and employer National Insurance contributions across all NI categories (A, B, C, H, J, M, V, X, Z, and others). Auto-enrolment assessment is run on each pay period and pension deductions are calculated and reported accordingly.
Statutory payments
The software handles the following statutory payment types: Statutory Maternity Pay (SMP), Statutory Sick Pay (SSP), Statutory Paternity Pay (SPP), Statutory Adoption Pay (SAP), and Shared Parental Pay (ShPP).
Variable hours and holiday pay
Zero-hours and variable-hours workers are supported within a single payroll scheme. Holiday pay for irregular-hours workers is calculated using the 52-week average method as required under UK employment law.
CIS payroll and subcontractors
Construction Industry Scheme (CIS) deductions are calculated automatically for registered subcontractors and submitted to HMRC alongside standard PAYE payroll. Gross payment status is supported.
Pay schedules
You can run weekly, fortnightly, four-weekly, or monthly pay schedules within the same account. Multiple pay schedules can run concurrently under a single employer PAYE scheme.
