Workplace pensions are now firmly embedded in UK employment law, yet TPR filing remains one of the most misunderstood and frequently missed employer obligations. Every year, thousands of UK businesses receive penalties from The Pensions Regulator (TPR) simply because they failed to file the right information on time even when pension contributions were being paid correctly.

For employers, understanding TPR filing requirements, re‑enrolment obligations and ongoing compliance duties is essential to avoid fines, enforcement action, and operational disruption.

This article explains what TPR filing is, who must complete it, key deadlines, common mistakes, and how employers can ensure ongoing compliance.

What Is TPR Filing?

TPR filing refers to the statutory requirement for employers to submit a Declaration of Compliance or Re‑Declaration of Compliance to The Pensions Regulator, confirming how they have met their automatic enrolment duties under the Pensions Act 2008.

There are two main filings employers must complete:

• Declaration of Compliance – after duties first start
• Re‑Declaration of Compliance – every three years following re‑enrolment

This filing is mandatory, regardless of business size, number of employees, or whether staff are actively contributing.

Who Must Complete TPR Filing?

Every UK employer with at least one worker must meet automatic enrolment duties and complete TPR filing. This includes:

• Limited companies
• Small and micro‑employers
• Employers with one employee
• Employers whose staff earn below the auto‑enrolment threshold
• Directors with employment contracts

Even if:

• No workers qualify for auto‑enrolment, or
• All eligible staff opt out

the employer must still submit the declaration or re‑declaration.

Declaration of Compliance: When Is It Due?

Employers must submit their first Declaration of Compliance within five months of their duties’ start date, which is typically the date their first employee starts work.

The declaration confirms:

• Which pension scheme is in place
• Which employees were assessed and enrolled
• Contribution levels being paid
• How employer duties are being met

Failure to submit this declaration even if everything else is correct is considered non‑compliance.

Re‑Enrolment and Re‑Declaration: The Three‑Year Cycle

Automatic enrolment is not a one‑off task.

Every three years, employers must:

1. Assess eligible staff who previously opted out or ceased saving
2. Re‑enroll qualifying staff back into the pension scheme
3. Submit a Re‑Declaration of Compliance to TPR

This applies even if no employees are required to be re‑enrolled, the re‑declaration must still be filed.

Employers must choose a re‑enrolment date within a six‑month window around their re‑enrolment anniversary and complete the re‑declaration within five months of that date.

What Are an Employer’s Ongoing Pension Duties?

TPR filing is just one part of ongoing compliance. Employers must also:

• Assess employee eligibility every pay run
• Automatically enroll eligible jobholders
• Pay at least minimum employer contributions
• Pass contributions to the pension provider on time
• Manage opt‑ins and opt‑outs correctly
• Keep accurate records for at least six years

TPR actively monitors payroll submissions and pension provider data and can identify missing or incorrect contributions.

How Much Must Employers Pay Into Workplace Pensions?

As of 2025/26, the minimum total contribution is 8% of qualifying earnings, made up of:

• Employer minimum: 3%
• Employee contributions: 5% (including tax relief)

Qualifying earnings currently sit between £6,240 and £50,270 per year, though employers may choose alternative schemes if they meet quality requirements.

What Happens if Employers Fail to File with TPR?

TPR has significantly increased enforcement activity in recent years. TPR data shows over 375,000 fines issued since automatic enrolment began, with tens of thousands issued annually.

Penalties include:

• Fixed Penalty Notice: £400
• Escalating Penalties:
  • £50/day (1–4 employees)
  • £500/day (5–49 employees)
  • Up to £10,000/day for large employers

Fines commonly arise from:

• Missing a declaration deadline
• Missing re‑declaration deadlines
• Failure to re‑enroll staff
• Incorrect or late contributions

Importantly, lack of awareness is not considered a reasonable excuse by TPR.

Common TPR Filing Mistakes Employers Make

From regulatory case reviews and industry data, the most common employer errors include:

• Assuming payroll or pension providers file on their behalf
• Forgetting three‑year re‑enrolment cycles
• Missing deadlines after staff opt‑outs
• Incorrect employee communications
• Poor record‑keeping
• Not updating TPR contact details

Many employers mistakenly believe that “nothing changes” after initial setup, this is a major compliance risk.

Why TPR Filing and Payroll Are Closely Linked

Workplace pensions are inseparable from payroll. Errors in payroll data often result in:

• Incorrect pension calculations
• Late or missing contributions
• Failed audits
• Automatic enforcement triggers

TPR cross‑checks:

• PAYE data from HMRC
• Pension provider contribution reports
• Employee complaints and tip‑offs

This makes accurate payroll processing and pension alignment critical.
