To plan for retirement in Hong Kong can overwhelm you. Hong Kong has one of the highest costs of living worldwide and its average life expectancy ranks among the longest . This makes it crucial to build a financial safety net. For workers and businesses, two retirement plans lead the discussion: the MPF (Mandatory Provident Fund) and ORSO (Occupational Retirement Schemes Ordinance).
But how do you figure out which one fits your situation best? Should you go with the government-controlled MPF, or check out the more adaptable, company-run ORSO? This guide explains the basics — so you can make a smart decision for your future.
What is ORSO?
The Occupational Retirement Schemes Ordinance (ORSO) came into effect in 1993 well before MPF became a must. ORSO is a retirement plan that companies sponsor created to offer more flexibility and custom-made perks for specific employees in big businesses and global companies.
In contrast to MPF, ORSO isn’t mandatory — it hinges on an employer’s decision to establish such a plan. Some ORSO schemes even have an exemption from MPF, which means workers don’t have to contribute to both systems.
Key Features of ORSO Schemes
- Benefits You Can Customize: Companies can shape the plan to match their workplace culture, field, and employee makeup.
- Optional Sign-Up: Workers can decide to join or not, based on the plan’s rules.
- Guaranteed Payout or Investment Growth: ORSO plans can promise a set amount (defined benefit) or let contributions grow with investments (defined contribution).
- Way to Keep Top Talent: ORSO often helps attract and keep high-level executives and foreign workers by offering perks beyond MPF.
Who Can Join ORSO?
The company decides who’s eligible, unlike MPF which follows a universal law. Some businesses limit ORSO membership to:
- Higher-ups or long-term workers
- Foreign nationals employed in Hong Kong
- Workers in niche fields
MPF Exemption
When an employee joins an MPF-exempt ORSO plan, they don’t have to take part in MPF. This benefits high-income earners in particular, as MPF contributions have a limit (HK$1,500 from both employer and employee). ORSO, on the other hand often gives higher contributions and more flexible options to withdraw.
Pros and Cons of ORSO
Pros
- Tailored structure and chance for better benefits
- Assists companies to draw in and keep top workers
- Might let employees bypass MPF’s contribution caps
Cons
- Harder to manage, with steeper compliance expenses
- Not a good fit for all company sizes small and medium enterprises
- Benefits differ by employer so they lack standardization
What is MPF?
The Mandatory Provident Fund (MPF), which started in 2000 serves as Hong Kong’s required retirement plan. It applies to almost all workers and self-employed individuals aged 18–64, except those exempt (like people covered by MPF-exempted ORSO schemes).
It’s a defined contribution plan where the employer and employee both pay into a personal account.
How Does MPF Work?
- Contribution Rates: Employers and employees each contribute 5% of the employee’s income to the fund. This has a limit of HK$1,500 per person monthly (HK$3,000 in total).
- Participation: Every employee and self-employed individual aged 18 to 64 must take part.
- Investment Choices: Workers can pick funds (stocks mixed assets conservative options, etc.) or opt for the Default Investment Strategy (DIS).
- Withdrawal: People can access their funds when they turn 65, or sooner in certain situations like leaving Hong Kong for good.

Advantages and Disadvantages of MPF
Advantages
- Required by law and the same for all industries
- Protected by law, with strong government oversight
- Offers a dependable cushion for retirement funds
Cons
- Limits on contributions cap the benefits for those earning more
- Not many choices for where to invest
- Taking money out is tough

Why Choose ORSO Over MPF (and Vice Versa)?
Companies choose ORSO or MPF based on their size, workforce makeup, and ability to manage the plan.
- To serve Large Corporations & MNCs: ORSO makes sense because it has an influence on customized benefits global mobility considerations, and executive retention.
- To serve SMEs: MPF is more practical. It’s straightforward, compliant, and needs little administrative work.
Example 1 – ORSO in Action
A global financial services firm in Central provides ORSO to its expatriate executives. Contributions go beyond MPF limits giving employees better retirement savings while the employer gains an edge in hiring.
Example 2 – MPF in Action
A local SME with 40 employees depends on MPF to meet legal requirements. While less flexible than ORSO, MPF ensures compliance without creating extra work.
