Employer pension contributions are the payments an employer makes into a workplace pension scheme on behalf of their employees. Under auto-enrolment, UK employers must contribute a minimum of 3% of qualifying earnings for eligible workers. Many employers contribute more as part of their overall benefits package.
Minimum Contribution Rates
The legal minimum under auto-enrolment since April 2019:
| Contributor | Minimum Rate |
|---|---|
| Employer | 3% of qualifying earnings |
| Employee | 5% of qualifying earnings (including tax relief) |
| Total | 8% of qualifying earnings |
Qualifying Earnings Band
Contributions are calculated only on the band of earnings between a lower limit and an upper limit. The Department for Work and Pensions reviews both limits each year, and the figures apply from 6 April; payroll and pension software apply the current annual, monthly and weekly amounts.
Contribution Example
For an employee earning £35,000 per year, using an illustrative lower limit of £6,000 (the upper limit is not reached):
| Step | Calculation | Amount |
|---|---|---|
| Qualifying earnings | £35,000 − £6,000 | £29,000 |
| Employer minimum (3%) | £29,000 × 3% | £870.00 |
| Employee minimum (5%) | £29,000 × 5% | £1,450.00 |
| Total minimum (8%) | £2,320.00 |
Enhanced Employer Contributions
Many employers offer contributions above the statutory minimum. Common structures include:
| Arrangement | How It Works |
|---|---|
| Flat rate | Employer contributes a fixed percentage (e.g. 6%, 8%, 10%) regardless of what the employee pays |
| Matching | Employer matches the employee’s contribution up to a cap (e.g. match up to 5%) |
| Tiered by service | Contribution rate increases with years of service (e.g. 3% in year 1, 5% after 3 years, 8% after 5 years) |
| Salary-banded | Different rates for different salary bands |
Enhanced pension contributions are a significant recruitment and retention tool. They should be clearly set out in the employment contract.
Tax Treatment of Employer Contributions
For the Employer
Employer pension contributions are:
- Tax-deductible as a business expense against corporation tax
- Exempt from employer National Insurance — unlike salary, pension contributions do not attract employer NIC
- Deductible for corporation tax in the accounting period in which they are paid, not when they are accrued
For the Employee
Employer contributions are:
- Not treated as a benefit in kind — no income tax or employee NIC charge
- Not reported on P11D forms
- Subject to the annual allowance, which limits total pension contributions receiving tax relief
Annual Allowance
The annual allowance applies to the total pension contributions from employer, employee and tax relief combined:
| Element | Rule |
|---|---|
| Standard annual allowance | The yearly limit for most people, set by HM Treasury |
| Tapered annual allowance | Reduced for people with very high adjusted income, down to a minimum |
| Money purchase annual allowance | A lower limit once someone has flexibly accessed a defined contribution pension |
Unused allowance from the previous three tax years can usually be carried forward. The current limits are published on GOV.UK.
If total contributions exceed the annual allowance, the employee faces an annual allowance charge on the excess, which is taxed at their marginal income tax rate.
Salary Sacrifice and Pension
Salary sacrifice is a common arrangement where the employee gives up part of their salary in exchange for an increased employer pension contribution. The result:
| Before Sacrifice | After Sacrifice |
|---|---|
| Employee earns £35,000 | Employee earns £33,250 (sacrificed £1,750) |
| Employer pension 3% = £870.00 | Employer pension = £870.00 + £1,750 = £2,620.00 |
| Employee pays income tax and NIC on £35,000 | Employee pays income tax and NIC on £33,250 |
| Employer pays NIC on £35,000 | Employer pays NIC on £33,250 |
Both employer and employee save on National Insurance. The employer must ensure the post-sacrifice salary does not fall below the National Living Wage.
Processing Pension Contributions Through Payroll
Pension contributions are calculated and processed as part of each PAYE payroll run:
- Payroll software calculates qualifying earnings for each employee
- Employee contributions are deducted from pay (under net pay or relief at source)
- Employer contributions are calculated and accrued
- Total contributions are reported through RTI
- Contributions are paid to the pension provider by the due date
- Deductions appear on the payslip and annual P60
Payment Deadlines
Contributions must reach the pension provider by the 22nd of the month following the month they were deducted (or the 19th for cheque payments). Late payments can trigger penalties from The Pensions Regulator.
Pension Contributions and Statutory Pay
Employer pension obligations continue during periods of statutory pay:
| Absence Type | Employer Pension Obligation |
|---|---|
| Statutory Maternity Pay | Continue contributions based on actual pay received |
| Statutory Paternity Pay | Continue contributions based on actual pay received |
| Statutory Sick Pay | Continue contributions based on actual pay received |
| Shared Parental Pay | Continue contributions based on actual pay received |
| Unpaid leave | No obligation unless contract states otherwise |
Accounting for Employer Pension Contributions
Pension contributions create regular entries in the employer’s accounting records:
| Transaction | Debit | Credit |
|---|---|---|
| Employer contribution accrual | Pension expense (P&L) | Pension provider payable (balance sheet) |
| Payment to provider | Pension provider payable | Bank |
Year-End Considerations
At the financial year-end, the employer should:
- Recognise a liability for contributions accrued but not yet paid
- Remember that accrued contributions unpaid at the year-end are deductible for corporation tax only in the period in which they are paid
- Disclose pension costs in the notes to the accounts where required
Employer Pension Costs as a Percentage of Salary
When budgeting for total staff costs, employers should factor in pension as a significant addition to gross salary:
| Component | Typical % of Gross Salary |
|---|---|
| Gross salary | 100% |
| Employer NIC (above the secondary threshold) | Varies with salary level |
| Employer pension (3-8%) | 3-8% |
| Total employer cost | Gross salary plus employer NIC and pension |
The NIC saving from salary sacrifice arrangements can partially offset the pension cost.
