ORSO Scheme Hong Kong 2027: ORSO vs MPF, Vesting & Withdrawal

An ORSO scheme is a voluntary retirement plan an employer sets up under Hong Kong's Occupational Retirement Schemes Ordinance, usually by banks, universities and other large employers. If the scheme is MPF-exempted, a new joiner gets a one-time choice between it and an MPF scheme: the employer must offer the choice within 10 days and you must reply in writing within 30 days, or you are treated as choosing MPF. Unlike MPF, the employer's share of an ORSO account normally vests gradually under a vesting scale, so you can lose part of it if you leave early. For members who joined after 1 December 2000, a protected slice called the minimum MPF benefits must be moved into an MPF scheme when you leave and can only be withdrawn at 65, on early retirement at 60, on permanently leaving Hong Kong, or on death, total incapacity or terminal illness.

This guide is for employees: what ORSO is, how it compares with MPF, what happens to your money when you change job or leave Hong Kong, and how the 2025 abolition of offsetting changed severance. For MPF itself, see our MPF guide for Hong Kong employees.

What Is an ORSO Scheme in Hong Kong?

ORSO stands for the Occupational Retirement Schemes Ordinance (Cap. 426). According to the MPFA's guide to the ordinance, it was enacted on 31 December 1992 and came into operation on 15 October 1993. It does not force employers to offer a pension. It sets up a registration system for the retirement schemes employers choose to run, so an "ORSO scheme" simply means a company retirement plan that is registered or exempted under that law.

The Mandatory Provident Fund Schemes Authority (MPFA) acts as the Registrar of Occupational Retirement Schemes. So the same regulator looks after both MPF and ORSO, even though the rules are different.

ORSO is far smaller than MPF but still significant. The MPFA's quarterly statistics show 2,980 ORSO schemes as at 30 June 2026, of which 2,187 were MPF-exempted. Registered schemes alone held about HK$311 billion for 253,065 members.

Defined contribution vs defined benefit ORSO schemes

There are two kinds of ORSO scheme, and the difference matters when you read your offer letter.

• Defined contribution (provident fund): you and the employer pay in a set percentage, and your benefit is whatever the account is worth. The MPFA's statistics show about 90% of all ORSO schemes are defined contribution.
• Defined benefit (pension style): your benefit comes from a formula, usually years of service multiplied by final salary. The MPFA's guide to the ordinance says these schemes must be reviewed by an actuary every three years.

Most expats who meet ORSO today are offered a defined contribution provident fund. If you are offered a defined benefit plan, ask for a projection of your benefit at your expected leaving date.

Who offers ORSO schemes?

ORSO schemes are run mainly by employers that had retirement plans before MPF started in December 2000 and kept them: international and local banks, insurers, universities and education bodies, utilities, airlines and other long-established large employers. Smaller firms and start-ups almost always use plain MPF.

You can't join an ORSO scheme on your own. The MPFA states that ORSO schemes must not be marketed to the public: membership only comes through your employer.

ORSO vs MPF: What Is the Difference?

The short version: MPF is compulsory, standardised and fully yours from day one. ORSO is set by the employer's scheme rules, can be more generous, but the employer's money usually comes with strings attached.

Two rows deserve a second look. Vesting is the big one, covered below. The other is preservation: in MPF, everything from mandatory contributions is locked until 65 (with limited exceptions), while in an ORSO scheme only a minimum slice is locked and the rest can often be paid to you in cash when you leave.

ORSO or MPF: Which Should You Choose?

You only get this choice if your employer runs both an MPF scheme and an MPF-exempted ORSO scheme that is open to new staff. Under the MPFA's rules the employer must give you the choice no later than 10 days after you become eligible, with information in English and Chinese on contributions, vesting, benefit structure and portability. You then have 30 days to reply in writing. Miss the deadline and you are deemed to have chosen MPF.

The MPFA describes this as a one-time choice, so treat it as a real decision rather than a form to sign during onboarding week.

When ORSO is usually the better pick

• The employer pays more than 5%. Ask for the exact employer contribution rate in writing. The reason ORSO can beat MPF is that some employers contribute well above the MPF minimum.
• You expect to stay long enough to vest. If full vesting arrives after, say, 10 years and you plan to stay five, model what you'd actually take away.
• The salary definition is generous. MPF caps relevant income at HK$30,000 a month, so above that level MPF employer contributions stop growing. An ORSO scheme that contributes a percentage of your full basic salary can be worth far more on a senior salary.

When MPF is usually the better pick

• You might leave within two or three years. Expats often do. With MPF, the employer's 5% is yours immediately.
• The vesting scale is steep. A scale that gives you nothing for the first few years is a retention tool, not a benefit, if you're likely to move.
• You want control of investments. Some ORSO schemes offer little or no fund choice.

Ask HR three questions before you choose: what is the employer contribution as a percentage of what salary, what is the vesting scale, and what happens to the unvested part if you resign or are made redundant. Get the answers in writing.

How Does ORSO Vesting Work and What Do You Lose If You Leave Early?

In a defined contribution ORSO scheme, the MPFA explains that a vesting scale in the governing rules sets what percentage of the employer-funded benefits you're entitled to, based on your years of service. Your own contributions are always yours.

Each scheme sets its own scale, so there is no standard one. A typical shape is a stepped scale. For illustration only:

Source: illustrative example only, not any particular employer's scheme. Check your own scheme rules.

On that example scale, someone who resigns after four years with HK$200,000 of employer-funded money in their account walks away with HK$60,000 of it. The other HK$140,000 is forfeited back to the scheme. That is why the vesting scale matters more than the headline contribution rate.

Can the employer take back money if you're dismissed?

Some ORSO scheme rules let the employer forfeit its share if a member is dismissed for cause. The MPFA says the trustee of an MPF-exempted scheme cannot forfeit your minimum MPF benefits in that situation, but can withhold the part above that minimum if the scheme rules allow it.

What about redundancy?

The MPFA notes that when employment ends through redundancy or severance, you normally receive your own balance plus the vested share of the employer's balance under the scale. Read the redundancy clause in your scheme rules rather than assuming it works like resignation.

What Are the Minimum MPF Benefits in an ORSO Scheme?

The minimum MPF benefits (MMB) are the part of your ORSO money that gets MPF-style protection. They apply to members who joined an MPF-exempted ORSO scheme after 1 December 2000. Members who joined on or before that date are exempt from the preservation, portability and withdrawal rules.

According to the MPFA, MMB is the lesser of two amounts:

1. Your accrued benefits for service since 1 December 2000: your own contributions plus the vested part of the employer's contributions.
2. The formula amount: final average monthly relevant income x years of post-MPF service x 1.2.

The income in the formula is capped at HK$30,000 a month for service from 1 June 2014 (HK$25,000 from 1 June 2012 to 31 May 2014, and HK$20,000 before that). The 1.2 figure is simply 10% (employer plus employee MPF contributions) x 12 months, so MMB is roughly what you would have built up in MPF.

A quick example: you earn HK$80,000 a month and leave after six years. The formula amount is HK$30,000 x 6 x 1.2 = HK$216,000. If your accrued ORSO benefits are HK$400,000, your MMB is HK$216,000 and the other HK$184,000 is handled under the scheme's own rules, which usually means it can be paid to you. The MPFA's minimum MPF benefits page sets out the calculation in full.

What Happens to Your ORSO When You Change Jobs?

When a post-2000 member leaves, the MMB must be transferred as soon as reasonably practicable to an MPF scheme: either one your new employer participates in, or a master trust or industry scheme you nominate that accepts the transfer. It cannot be paid to you in cash at that point.

Whatever is left after the MMB transfer can be withdrawn under the ORSO scheme's governing rules. In practice that often means a cheque or bank transfer for the excess. Some trustees also offer a deferred member account so you can leave the money invested.

Here is how a typical exit looks:

1. Ask HR for your benefit statement. You are entitled to a detailed description of your benefits within three months of leaving, according to the MPFA.
2. Check your vesting date. If you're a few months short of the next vesting step, it can be worth timing your resignation around it.
3. Nominate the MPF scheme for your MMB. Use your new employer's scheme or a personal account you already hold.
4. Collect the excess. Confirm the payment method and whether any of it is taxable (see the tax section below).

Your MMB lands in MPF and from then on follows normal MPF rules, including the age 65 lock. Our MPF guide covers consolidating and choosing funds.

Can You Withdraw ORSO When Leaving Hong Kong?

Yes, but only in two pieces.

The MMB can only be withdrawn on the MPF grounds: reaching 65, early retirement at 60 or above, permanent departure from Hong Kong, total incapacity, terminal illness or death. So if you leave Hong Kong for good, you can claim the MMB under the permanent departure ground once it sits in an MPF scheme.

The balance above the MMB is paid under the ORSO scheme's own rules, and usually doesn't need any MPF ground at all. In practice, leavers usually receive the excess from the ORSO trustee after they leave, then claim the MMB from MPF separately.

Leaving Hong Kong involves a lot of other admin too. Our leaving Hong Kong checklist puts ORSO and MPF in order alongside tax clearance, bank accounts and your lease.

How Does the 1 May 2025 Abolition of Offsetting Affect ORSO Members?

Before 1 May 2025, employers could use the vested employer-funded part of your MPF or ORSO account to reduce the severance payment (SP) or long service payment (LSP) they owed you. That offsetting was abolished from the "transition date" of 1 May 2025 for employees who cease employment on or after that date.

ORSO contributions aren't split into mandatory and voluntary parts like MPF, so the Labour Department divides the vested employer benefits into two:

• Carved-out benefits: the "MPF-equivalent" slice. It is based on your average monthly relevant income over the 12 months before termination (capped at HK$30,000) and your years of service from 1 December 2000. Trustee guidance, such as HSBC's ORSO FAQ, spells this out as average monthly relevant income x years of service x 5% x 12. This slice cannot offset SP or LSP for service from 1 May 2025, but can still offset the pre-transition portion.
• Remaining benefits: everything vested above the carved-out slice. This still can be used to offset SP or LSP for service both before and after 1 May 2025.

If you joined before 1 May 2025, your SP or LSP is split in two at the transition date. The pre-transition portion is calculated on your last full month's wages before 1 May 2025 and can still be offset. The post-transition portion is calculated on your last full month's wages before termination. Total SP or LSP is capped at HK$390,000. The Labour Department's page on ORSO members and the abolition of offsetting has worked examples.

The practical point for ORSO members: a generous ORSO scheme with large remaining benefits can still reduce your severance. Ask HR whether the scheme rules allow offsetting against the remaining benefits before you sign. For how SP and LSP are calculated, read our severance and long service payment guide.

How Is ORSO Taxed in Hong Kong?

The contributions side is straightforward. The MPFA says employee contributions to ORSO schemes are tax-deductible up to HK$18,000 a year, and employer contributions are deductible for the employer up to 15% of the employee's total salary.

The payout side has one trap. Under the Inland Revenue Department's Departmental Interpretation and Practice Note No. 23, a lump sum from a recognised occupational retirement scheme paid on termination of service is exempt only up to the "proportionate benefit":

• Proportionate benefit: accrued employer-funded benefit x completed months of service / 120.
• Ten years or more: the fraction is 1 or more, so the whole employer-funded lump sum is exempt.
• Under ten years: the employer-funded part above the proportionate benefit is taxable as salary in the year you leave.

The IRD's own example uses HK$100,000 of employer-funded benefits after 72 months: HK$60,000 is exempt and HK$40,000 is taxable. In practice, the vesting scale often keeps the vested amount below the proportionate benefit, so many leavers pay nothing extra, but check before you file. A lump sum on retirement from commuting a pension is not taxable, while a monthly pension is fully taxable, according to the IRD.

The taxable excess goes on your final tax return. Our Hong Kong salaries tax guide explains rates and allowances.

Common Mistakes With ORSO Schemes

• Ignoring the 30-day deadline. Silence means MPF. If you wanted ORSO, you've lost the choice.
• Comparing contribution rates without the vesting scale. A 10% employer contribution that vests after 10 years is worth less than MPF's 5% if you leave in year three.
• Resigning weeks before a vesting step. Check the date your next vesting percentage kicks in.
• Assuming all of it is locked until 65. Only the MMB is. The excess is often paid out when you leave.
• Forgetting the tax on the excess. If you leave before 10 years, part of the employer-funded payout can be taxable.
• Not asking about offsetting. Remaining benefits can still reduce your severance or long service payment after 1 May 2025.

FAQs: ORSO Schemes in Hong Kong

What does ORSO stand for?

ORSO stands for the Occupational Retirement Schemes Ordinance, Cap. 426 of the Laws of Hong Kong. It came into operation on 15 October 1993 and regulates voluntary retirement schemes run by employers. The MPFA acts as the Registrar.

Is ORSO better than MPF?

It depends on the employer contribution rate, the vesting scale and how long you'll stay. ORSO can pay more if the employer contributes above 5% or on salary above the HK$30,000 MPF cap. MPF wins if you might leave early, because its employer contributions vest immediately.

Can I switch from ORSO to MPF later?

Normally no: the choice is offered once, when you first become eligible. The main exception is when your employer reduces future benefits under an MPF-exempted ORSO scheme, in which case members must be offered the option to join an MPF scheme instead.

What happens if I don't choose between ORSO and MPF?

You are deemed to have chosen MPF. Your employer must give you the choice within 10 days of becoming eligible, and you have 30 days to reply in writing.

How much is the minimum MPF benefit?

It is the lesser of your accrued ORSO benefits for post-December 2000 service and final average monthly relevant income x years of post-MPF service x 1.2. Relevant income is capped at HK$30,000 a month for service from June 2014. It only applies to members who joined after 1 December 2000.

Can I take my ORSO money out when I resign?

Partly. The minimum MPF benefits must go into an MPF scheme and stay there until an MPF withdrawal ground applies. The balance above that is paid under the scheme rules, which usually allows a cash payment on leaving.

Do I lose my ORSO if I'm fired?

Not all of it. Your own contributions and the minimum MPF benefits are protected. If you are dismissed for cause, some schemes let the employer withhold the vested employer money above the minimum MPF benefits.

Can I withdraw ORSO if I leave Hong Kong permanently?

Yes. The minimum MPF benefits can be claimed from your MPF scheme on the ground of permanent departure from Hong Kong, and the excess is paid under the ORSO scheme's own rules. Expect to handle the two pieces separately.

Are ORSO contributions tax-deductible?

Yes. Employee contributions are deductible up to HK$18,000 a year. Employers can deduct their contributions up to 15% of the employee's total salary.

Is my ORSO lump sum taxable?

The employer-funded part paid on leaving is exempt up to the proportionate benefit: completed months of service divided by 120. After 10 or more years with the employer, it is fully exempt. Before that, any excess is taxed as salary in the year you leave.

Key Takeaways

• ORSO schemes are voluntary employer retirement plans regulated by the MPFA; there were 2,980 of them at 30 June 2026, 2,187 of them MPF-exempted.
• With an MPF-exempted ORSO, your employer must offer the ORSO or MPF choice within 10 days, and you have 30 days to reply in writing or you default to MPF.
• MPF employer contributions vest immediately; ORSO employer contributions usually vest on a scale by years of service, so leaving early can cost you part of the employer's money.
• Minimum MPF benefits (lesser of accrued benefits and income capped at HK$30,000 x years since Dec 2000 x 1.2) must move to MPF when you leave.
• Minimum MPF benefits can be withdrawn at 65, at 60 on early retirement, on permanent departure from Hong Kong, or on death, total incapacity or terminal illness.
• From 1 May 2025, carved-out ORSO benefits can no longer offset severance or long service payment for service after that date, but remaining benefits still can.
• Employee ORSO contributions are tax-deductible up to HK$18,000 a year, and employer-funded lump sums are fully tax-free only after 120 completed months of service.
