Limitation Period: Bonus Payment Disputes

Bonus payment disputes are a frequent source of employment litigation in England and Wales. They arise where an employee or worker believes they are contractually entitled to a bonus that has not been paid, has been reduced, or has been calculated incorrectly. These disputes often involve interpretation of employment contracts, discretionary bonus schemes, and performance-related pay structures.

A critical issue in all bonus disputes is the limitation period, which sets the strict time limit for bringing a claim in either the Employment Tribunal or civil courts. The applicable time limit depends on how the claim is framed, the type of bonus involved, and whether the claim is based on contract, unlawful deduction from wages, or breach of statutory rights.

Legal Nature of Bonus Payment Disputes

Bonus claims may arise under several legal bases:

1. Contractual entitlement

Most bonus disputes are based on employment contracts or bonus schemes. These may be:

• Guaranteed contractual bonuses
• Discretionary bonuses subject to performance criteria
• Commission-based schemes tied to sales or targets

If a bonus forms part of the contract, failure to pay may constitute breach of contract.

2. Unlawful deduction from wages

Under the Employment Rights Act 1996, wages include many forms of remuneration. In some cases, bonuses are treated as wages if they are:

• Clearly ascertainable
• Contractually payable
• Not genuinely discretionary

Where this applies, claims may be brought for unlawful deduction from wages.

3. Discrimination claims involving bonuses

Bonus disputes may also arise in discrimination contexts, for example:

• Unequal bonus allocation based on protected characteristics
• Reduced bonus during maternity leave or sickness absence

These claims fall under the Equality Act 2010 and follow separate limitation rules.

Limitation Periods for Bonus Payment Disputes

1. Employment Tribunal claims: 3 months less one day

For most employment-related bonus claims, the limitation period is:

• Three months less one day from the date of the breach or deduction

This applies to:

• Unlawful deduction from wages claims
• Many contractual claims brought in the Employment Tribunal
• Some discrimination-related bonus disputes

The limitation period is strictly enforced by tribunals.

When Does Time Start Running?

The starting point depends on the type of claim:

Unpaid bonus (contractual entitlement)

Time usually runs from:

• The date the bonus was due under the contract or scheme

Reduced or discretionary bonus

Time runs from:

• The date the employer communicates the decision to reduce or refuse payment

Series of deductions

If a bonus is paid in instalments or subject to repeated underpayment:

• Each underpayment may trigger a separate limitation period
• However, a “series of deductions” rule may apply in wage claims

ACAS Early Conciliation and Time Limits

Before issuing most Employment Tribunal claims, claimants must notify ACAS for Early Conciliation.

This affects limitation periods as follows:

• The limitation clock is paused during Early Conciliation
• Time resumes once the ACAS certificate is issued
• A short extension is granted after the certificate to issue proceedings

However:

• Early Conciliation does not revive an expired claim
• It must be started before the deadline expires

Civil Court Claims for Bonus Disputes

Where bonus disputes are pursued as breach of contract in the civil courts (rather than Employment Tribunal), the limitation period is:

• 6 years from the date of breach
  (Limitation Act 1980, section 5)

This typically applies where:

• The claimant is no longer employed
• The claim exceeds tribunal jurisdiction limits
• The dispute is purely contractual and not framed as wages

Key Distinction: Tribunal vs Court Claims

Employment Tribunal

• Short limitation period (3 months less one day)
• Covers wages, unlawful deductions, and employment rights

Civil courts (County Court or High Court)

• Longer limitation period (6 years)
• Covers breach of contract claims for bonuses not treated as wages

Choosing the correct forum is critical, as it directly affects whether the claim is in time.

Continuing Bonus Disputes

Some bonus schemes involve ongoing assessments or repeated decisions. In such cases:

• Each bonus cycle may create a separate cause of action
• A single refusal decision starts time for that year's bonus
• Ongoing underpayment does not necessarily extend limitation

Courts distinguish between:

• A single breach with continuing consequences
• Separate breaches each triggering their own limitation period

Discretionary Bonus Schemes and Limitation Issues

Discretionary bonuses often generate disputes over whether discretion was properly exercised. Even where discretion exists:

• Employers must not act irrationally or capriciously
• Discretion must be exercised in good faith under contract principles

Limitation still runs from:

• The date the discretionary decision is communicated

Employees cannot delay limitation simply because they are challenging fairness internally.

Exceptions and Extensions

1. Not reasonably practicable test (tribunal claims)

In limited cases, time may be extended if it was not reasonably practicable to present the claim in time. This is narrowly applied.

2. ACAS conciliation extension

Provides limited additional time but does not override expired deadlines.

3. Disability or incapacity

Rarely, limitation may be extended where the claimant lacked capacity.

4. Fraud or concealment

If bonus calculations are deliberately concealed, section 32 of the Limitation Act 1980 may postpone the limitation period in civil claims.

Practical Steps in Bonus Disputes

1. Identify bonus classification

Determine whether the bonus is:

• Contractual
• Discretionary
• Commission-based
• Wage-related

2. Establish key dates

• Contractual due date
• Employer decision date
• Payment date or refusal

3. Determine correct forum

• Employment Tribunal (short limitation)
• Civil court (long limitation)

4. Check ACAS Early Conciliation timing

Ensure notification is made before expiry.

5. Prepare claim documentation

Includes:

• Employment contract
• Bonus scheme rules
• Performance evidence
• Payroll records

Risks of Missing the Limitation Period

If the limitation period expires:

• The claim is usually barred entirely
• Tribunals and courts will refuse to hear it
• Employers gain a complete defence
• Recovery of unpaid bonus becomes impossible

Bonus disputes are particularly sensitive to timing because employers often rely on strict contractual deadlines and discretionary wording.

Common Questions

Is a discretionary bonus ever legally enforceable?

Yes, if discretion is exercised irrationally, in bad faith, or contrary to contractual terms.

Does raising a grievance extend limitation?

No. Internal processes do not stop or extend legal deadlines.

Can I claim unpaid bonuses after leaving employment?

Yes, but only within the applicable limitation period (3 months in tribunal or 6 years in civil court).

Key Takeaways

Bonus payment disputes in England and Wales are governed by strict limitation rules that depend on whether the claim is brought in the Employment Tribunal or civil courts. Tribunal claims generally must be issued within three months less one day, while contractual claims in civil courts allow six years. The limitation period usually begins when the bonus is due or when the employer makes a payment decision. ACAS Early Conciliation can pause time but does not revive expired claims. Correct classification of the bonus and prompt action are essential to preserve legal rights.
