Pensions on payslips — pillar hub
Workplace pension contributions appear on payslips in three different ways: net-pay arrangement, relief-at-source, and salary sacrifice. Each affects taxable pay, NIable pay and your effective contribution rate differently.
Educational guidance only. Not affiliated with HMRC. Not regulated tax, legal, financial, payroll or employment advice.
The three setups, in plain English
- Net-pay arrangement. Contribution deducted before tax. Reduces taxable pay. NIable pay unchanged.
- Relief-at-source (RAS). Deducted after tax. Provider claims 20% relief and adds to your pot. Higher-rate taxpayers claim extra via Self Assessment.
- Salary sacrifice. You give up gross salary in return for an employer pension contribution. Reduces both taxable and NIable pay.
Quick answer — why does my pension contribution look high?
A pension contribution looks high when shown as a percentage of total earnings rather than qualifying earnings, when salary sacrifice is misconfigured, or when an employer match is included on a single line.
