Auto-enrolment payroll software for UK employers
Nxsys handles your workplace pension duties inside payroll. It assesses every employee on every pay run, enrols the ones who qualify, sends the statutory letters and submits contributions to your pension provider.
What is pension auto-enrolment?
Every UK employer must put eligible staff into a workplace pension and pay into it. Employees aged 22 to State Pension age who earn more than £10,000 a year must be enrolled, and the minimum total contribution is 8% of qualifying earnings, with at least 3% from the employer.
Assess
Each employee is checked on age and earnings each time you run payroll.
Enrol
Eligible staff are enrolled and told in writing, and opt-outs are handled.
Re-enrol
Staff who opted out are re-enrolled, and you declare compliance to The Pensions Regulator.
Nxsys follows the rules for you, so you meet your duties without tracking thresholds by hand.
