ORSO Schemes in Hong Kong: Employer Compliance and Key Differences from MPF

What Are ORSO Schemes?

An Occupational Retirement Scheme, or ORSO scheme, is an employer-sponsored retirement scheme registered under the Occupational Retirement Schemes Ordinance (Cap. 426). These schemes are privately administered and can replace or supplement the Mandatory Provident Fund (MPF) system.

The key distinction is that ORSO schemes are voluntary arrangements set up by individual employers. MPF is a statutory requirement covering most employees.

ORSO schemes predate the MPF system, introduced in 2000. Many long-established employers in Hong Kong maintain ORSO schemes as their primary retirement vehicle. The Mandatory Provident Fund Schemes Authority oversees both MPF and ORSO compliance. ORSO schemes carry their own registration and reporting requirements under Cap. 426.

ORSO vs MPF Hong Kong

The fundamental difference between ORSO and MPF lies in structure and flexibility. MPF is a defined contribution scheme: both employer and employee contribute 5% of relevant income, capped at monthly relevant income of HK$30,000. ORSO schemes can be defined contribution, defined benefit, or hybrid arrangements.

Contribution flexibility is the clearest differentiator. ORSO schemes let employers set contribution rates and control vesting schedules. They also determine the benefit formula. MPF contribution rates are fixed by law.

Vesting works differently. ORSO schemes can have graded vesting periods, meaning employees may only become entitled to employer contributions after a specified period of service. MPF employer contributions vest immediately.

Investment choice also diverges. ORSO schemes may offer limited investment options or be pooled. MPF members generally have broader fund choices.

An employer may apply for an ORSO exemption from MPF for employees covered by a registered ORSO scheme that meets minimum benefit standards.

ORSO Scheme Registration Hong Kong

Register the scheme with the Registrar of Occupational Retirement Schemes under Cap. 426 before operating it. The registration process has three stages.

First, scheme design. The employer drafts the trust deed and rules governing the scheme, with the assistance of a scheme administrator or trustee.

Second, application submission. The employer submits the application to the Registrar, including the trust deed, actuarial valuation (for defined benefit schemes) and supporting documents.

Third, approval and certificate. Once approved, the Registrar issues a certificate of registration. The scheme must be registered within three months of establishment.

The scheme administrator handles ongoing compliance: filing annual returns and notifying the Registrar of any changes to the scheme rules or trustee.

ORSO Employer Obligations

Employers maintaining an ORSO scheme carry several ongoing obligations under Cap. 426.

Make contributions. The employer must pay the employer contribution as specified in the scheme rules. Employee contribution may also be required if the scheme provides for it.

Maintain records. Keep accurate records of contributions, accrued benefits and membership details for at least six years.

Notify the Registrar of any change to the scheme rules, trustee or administrator within 30 days.

File annual returns. The scheme administrator files an annual return with the Registrar within six months of the scheme's anniversary date.

Provide information to members. Employees must receive periodic benefit statements and scheme rule summaries.

Failure to comply can result in penalties, including fines and potential revocation of the scheme's registration.

ORSO Exemption From MPF

An employer may apply for an ORSO exemption from MPF for employees who are members of a registered ORSO scheme. The exemption applies only if the ORSO scheme meets the minimum benefit standards set by the Mandatory Provident Fund Schemes Authority. These standards require that the ORSO scheme provides benefits at least equivalent to those under MPF.

The exemption application is made to the MPFA. If granted, the employer is not required to make mandatory MPF contributions for those employees. The employer must still comply with MPF requirements for any employees not covered by the ORSO scheme.

The exemption is not automatic. The MPFA assesses whether the ORSO scheme meets the prescribed standards, including minimum vesting requirements and contribution levels. If the scheme fails to meet these standards, the exemption may be refused or revoked.

Vesting and Accrued Benefits

Vesting refers to the employee's entitlement to the employer contribution and any investment returns on those contributions. In ORSO schemes, vesting schedules are set out in the scheme rules.

Immediate vesting means the employee is entitled to all employer contributions from day one. Graded vesting gives the employee a percentage of employer contributions after each year of service, reaching full vesting after a specified period , for example, 20% per year over five years. Cliff vesting entitles the employee to all employer contributions after a specified period, such as three years.

Accrued benefits are the total benefits the employee has earned under the scheme: employer and employee contributions plus any investment returns. The scheme rules determine how accrued benefits are calculated and when they are payable.

Offsetting and the Abolition of MPF Offsetting

Before 1 May 2025, employers could use accrued benefits from mandatory MPF contributions to offset severance payment or long service payment payable under the Employment Ordinance (Cap. 57). This offsetting arrangement was abolished with effect from 1 May 2025.

The abolition has no retrospective effect. For employees whose employment began before 1 May 2025, accrued benefits from mandatory contributions may still offset the portion of severance or long service payment calculated on years of service before that date. For service on or after 1 May 2025, no offsetting is permitted.

Accrued benefits from voluntary contributions and gratuities based on length of service may still be used to offset severance or long service payment. The Government runs a subsidy scheme sharing employers' expenses on severance and long service payment for service on or after 1 May 2025.

For ORSO schemes, the offsetting rules apply differently. ORSO benefits that are gratuities based on length of service may still offset severance or long service payment, subject to the scheme rules and the Employment Ordinance.

Trustee and Scheme Administrator

Every ORSO scheme must have a trustee and a scheme administrator. The trustee holds the scheme assets in trust for the members. The trustee is responsible for investment management and benefit payments. The scheme administrator handles day-to-day administration: record-keeping, contribution collection and member communications.

The trustee must be approved by the Registrar and must meet fit and proper person requirements. The scheme administrator may be the employer itself or a third-party provider. Both the trustee and administrator have fiduciary duties to act in the best interests of scheme members.

Voluntary Contributions and Gratuities

ORSO schemes may allow voluntary contributions from employees or employers. These are additional amounts beyond the mandatory or scheme-required contributions. Voluntary contributions may be subject to different vesting and withdrawal rules.

Gratuities are lump-sum payments based on length of service, often paid on retirement or termination. In ORSO schemes, gratuities may be structured as part of the benefit formula. Gratuities based on length of service may still be used to offset severance or long service payment, even after the abolition of MPF offsetting.

Compliance Checklist for Employers

• Register the scheme under Cap. 426 before operating it.
• Appoint a trustee and administrator. Both must be approved and meet regulatory requirements.
• Make contributions on time. Late contributions may incur penalties and interest.
• File annual returns with the Registrar within the prescribed timeframe.
• Notify changes to scheme rules, trustee or administrator within 30 days.
• Provide member statements at least annually.
• Review vesting schedules to ensure they comply with the scheme rules and any applicable MPF exemption standards.
• Monitor MPF exemption status. If the scheme has an MPF exemption, ensure it continues to meet the minimum benefit standards.
• Prepare for offsetting abolition. Review how the abolition of MPF offsetting affects severance and long service payment calculations for ORSO members.
