## What are my auto-enrolment duties as a small employer?

Under the Pensions Act 2008, all UK employers must automatically enrol eligible workers into a qualifying workplace pension scheme and make financial contributions on their behalf.

These legal duties apply to every business from the very day your first member of staff starts working, even if you only employ one person. To remain fully compliant with the regulations, you must perform nine core administrative and financial tasks.

1. Choose a qualifying pension scheme that meets statutory criteria.
2. Assess your workforce's eligibility at every pay reference period.
3. Enrol eligible workers and write to them to explain their rights.
4. Provide written information to staff who do not meet the automatic enrolment criteria.
5. Deduct employee contributions and pay minimum employer contributions into the scheme.
6. Submit a formal declaration of compliance to The Pensions Regulator.
7. Process opt-out requests within the statutory window and refund contributions.
8. Re-enrol eligible staff who have previously opted out every three years.
9. Keep accurate, updated records of assessments, contributions, and opt-out notifications.

## Who do I have to enrol in a workplace pension?

You must assess every staff member at each pay run to determine their enrolment category based on their age and gross earnings.

Your legal obligations differ significantly depending on which category your workers fall into during the pay reference period. Eligible jobholders must be enrolled automatically, non-eligible jobholders have a right to opt in with employer contributions under section 7 of the Pensions Act 2008, and entitled workers hold the right to join a scheme without mandatory employer contributions under section 9 of the Act.

| Worker Category | Age Threshold | Earnings Threshold | Employer Actions Required |
| --- | --- | --- | --- |
| Eligible Jobholder | Aged 22 to State Pension age | Over £10,000 per year (£833/month) | Must automatically enrol and pay employer contributions. |
| Non-eligible Jobholder | Aged 16 to 21, or State Pension age to 74 (earning over £10,000); OR aged 16 to 74 (earning £6,240 to £10,000) | Over £6,240 up to £10,000 per year | Do not enrol automatically. Must enrol and contribute if they opt in. |
| Entitled Worker | Aged 16 to 74 | Under £6,240 per year (£120/week) | Must set up a scheme if they ask to join. Employer contribution optional. |

## How much do I need to contribute to the pension?

You must pay a minimum of 3% of your employee's qualifying earnings, with the total minimum contribution from both parties reaching at least 8%.

Qualifying earnings are calculated as a band of gross earnings. For the 2026/27 tax year, this band is set between £6,240 and £50,270 per year, which includes salary, wages, bonuses, commission, and statutory pay.

| Contributor | Minimum Contribution Rate | Calculation Basis |
| --- | --- | --- |
| Employer | 3% | Calculated on qualifying earnings between £6,240 and £50,270. |
| Employee | 5% (includes tax relief) | Deducted directly from gross pay in the pay run. |
| Total Minimum | 8% | Combined mandatory minimum funding rate. |

Pension contributions must be paid over to the pension scheme provider by the 22nd day of the calendar month following the payroll deduction.

## How do I choose a workplace pension scheme?

You must select a qualifying pension scheme that is formally recognized and meets the strict criteria set out by The Pensions Regulator.

When choosing a scheme, ensure that it accepts your payment methods and will integrate with your existing payroll software. Many small and micro-businesses choose NEST, the National Employment Savings Trust, because it was established by the government specifically to accept any employer regardless of size.

## Can I postpone pension auto-enrolment?

Yes, you can choose to delay assessing your staff for a period of up to three months from your duties start date.

This postponement period can also be applied to newly hired employees or when an existing worker passes a qualifying threshold. If you choose to postpone, you must write to the affected workers within six weeks of the postponement start date to notify them of this action.

## How do pension opt-outs and refunds work?

Enrolled employees have a legal right to opt out of your workplace pension within a strict one-month opt-out window.

This window begins on either the date active membership is created, or the date the employee receives their enrollment letter, whichever is later. Under sections 2 and 54 of the Pensions Act 2008, employers are strictly prohibited from offering financial incentives or encouraging staff to opt out.

## Do I need to re-enrol my staff?

You must carry out cyclical re-enrolment duties every three years to re-evaluate staff who previously opted out of your pension scheme.

You must automatically re-enrol any staff members who opted out more than 12 months prior and still meet the eligible jobholder criteria. After completing this process, you must submit a formal re-declaration of compliance to The Pensions Regulator within five months of your re-enrolment date. All associated pension records must be safely kept for a minimum of six years.

## What happens if I fail to comply with TPR?

The Pensions Regulator possesses strong legislative enforcement powers under sections 35 to 45 of the Pensions Act 2008.

- An initial statutory warning notice or directive to correct compliance failures.
- An immediate £400 fixed penalty notice if you miss deadlines or ignore warnings.
- Escalating daily penalties ranging from £50 to £10,000 per day depending on the size of your workforce.
- Criminal prosecution under section 45 of the Act, which carries penalties of up to two years' imprisonment for wilful non-compliance.

## Are director-only companies exempt from auto-enrolment?

Companies that only employ directors and have no other staff are generally exempt from auto-enrolment duties.

This exemption applies if the directors do not have written contracts of employment with the company. However, if your company employs even one non-director worker, or if a director has an active employment contract, the duties apply in full.

### Do I have to set up auto-enrolment if I only have one employee?

Yes, duties apply to you if you employ at least one worker who meets the eligibility criteria, regardless of your business structure or overall staff numbers.

### What is the scheme of compliance deadline for a new business?

You must submit your declaration of compliance to The Pensions Regulator within five months of your first duties start date, which is the day your first employee begins working.

### Can a small employer use NEST as their workplace pension?

Yes, NEST is a government-backed qualifying pension scheme designed to accept any UK employer, making it a reliable choice for micro-businesses.

### Can employees choose to opt out of the workplace pension scheme?

Yes, employees can opt out within one month of active registration. Employers must refund any deductions taken during this window and are legally barred from encouraging opt-outs.

### What are qualifying earnings for auto-enrolment in the 2026/27 tax year?

Qualifying earnings are the portion of an employee's gross pay falling inside the statutory band between £6,240 and £50,270 per year.
