Critical Deadline Alert: IR56G Departure Clearance
Under the Inland Revenue Ordinance, your employer is legally obligated to file Form IR56G at least one month before your departure date. If the employer fails to file — which happens in approximately 1 in 4 expat departures — the IRD can issue a stop-departure notice, prevent you from leaving Hong Kong, and raise an estimated assessment that may be many times higher than your actual tax liability. We have seen assessments of HK$2 million+ when the actual liability was under HK$200,000. Do not leave this to chance or your HR department alone.
Five Costly Expat Tax Traps in Hong Kong
Most foreign professionals are surprised by the number of tax pitfalls waiting for the uninformed. Each of the following is entirely preventable — but only if you know they exist.
Double Taxation Without a Treaty Claim
Hong Kong has CDTAs with 45+ jurisdictions including the UK, France, Japan, Korea, and the Mainland. However, DTA relief is not automatic — it must be actively claimed in both countries. Without a coordinated filing strategy, you legally owe tax in two countries on the same salary. UK residents, for example, are taxed on worldwide income, meaning HK-sourced income is taxable in both jurisdictions unless the treaty exemption or credit is correctly elected on your Self Assessment return.
RSUs and Share Options Taxed in the Wrong Year
Under IRO s.9(1)(d) and DIPN No. 38, RSUs are taxed at vesting while options are taxed at exercise — not grant. The taxable amount must be apportioned to reflect only HK-sourced service. If options were granted before your Hong Kong arrival or vest after departure, the HK-taxable portion is a fraction of the total. Employer-submitted IR56B forms routinely apply the wrong date and wrong apportionment, generating substantial overpayments that can be recovered.
Rental Allowance Assessed at Full Market Value
Employer-provided housing structured as a company lease is assessable under IRO s.9(2A) at only 10% of your net chargeable income — not at full market rental value. If the arrangement is structured as a cash housing allowance instead, you pay tax on the full amount. The difference can exceed HK$200,000 per year for senior executives. Many employers default to cash allowances for administrative simplicity, at significant cost to the employee.
Departure Clearance Missed or Filed Too Late
Form IR56G must be lodged by your employer at least one month before your departure. If the filing is late or omitted, the IRD may raise a provisional assessment based on estimated earnings with no deductions applied. These estimates are often two to five times the actual liability. We have resolved dozens of departure clearance disputes where clients faced phantom assessments and potential stop-departure orders, recovering or avoiding hundreds of thousands in over-assessed tax.
The 183-Day HK-Mainland Rule Misunderstood
Under the 2006 HK-Mainland Comprehensive Arrangement (updated), if you are present in mainland China for 183 days or more in a tax year, your Hong Kong salary becomes potentially fully taxable in the Mainland — at PRC Individual Income Tax rates that reach 45%. Careful day-count tracking, combined with the correct split-payroll structure documented under both authorities, is essential for any executive who regularly crosses the border.
Built Specifically for Foreign Nationals in Hong Kong
Our expat tax practice handles the full spectrum of foreign national tax situations — from newly-arrived professionals filing their first HK return, to long-term residents managing complex multi-jurisdiction portfolios, to departing executives navigating clearance and final assessments.
- Foreign nationals on Employment Visa (all categories) — newly arrived or established
- Executives on expat packages with split contracts (HK + home country)
- Bankers, finance professionals, and legal partners with equity / bonus structures
- Regional managers with HK as primary base but regular Mainland presence
- Dependent visa holders who take on part-time or freelance work in HK
- Executives with unvested RSUs and options from pre-HK employment
- Foreign nationals departing HK requiring IR56G and final assessment management
- US persons (FATCA) requiring coordinated HK and US filing strategies
- Expats with overseas pension income (generally HK tax-free — but must be correctly structured)
- Foreign employees objecting to IRD assessments or employer-submitted IR56B errors
Client Snapshot: UK Investment Banker
A Managing Director at a Tier 1 bank arrived in Hong Kong on a split contract — 60% of salary paid in HK, 40% retained in a UK entity. His employer's IR56B incorrectly reported 100% of RSU vestings as Hong Kong-sourced. Over three years, he had overpaid Hong Kong salaries tax by a substantial amount.
Our team identified the DIPN 38 time-apportionment error, prepared amended returns for all three years, and successfully obtained a tax refund from the IRD — while simultaneously coordinating with his UK accountants to ensure Foreign Tax Credit claims were correctly adjusted in his HMRC Self Assessment.

IRO s.64, s.66, s.68Back-Year Assessment Review
The IRD can raise assessments going back up to 6 years in cases of negligence, and up to 10 years for fraud or wilful evasion. We conduct a complete back-year review of all your HK filings to identify any errors — whether in your favour or the IRD's — and correct them proactively before the IRD raises them.

For US citizens and Green Card holders, HK income must be reported on Form 1040 alongside the FBAR (FinCEN 114) and potentially Form 8938.

UK Investment Banker on Split Contract: HK$340,000 Overpayment Recovered
A senior Managing Director at a global investment bank had been employed in Hong Kong for four years on a split contract — his base salary was split 65/35 between a Hong Kong entity and a UK entity. Annually, his employer filed IR56B forms reporting 100% of all RSU vestings as Hong Kong-sourced income, without applying the DIPN No. 38 time-apportionment methodology.
The RSU awards had been granted over a three-year vesting schedule. For awards granted before his Hong Kong arrival, a significant portion of the vesting period occurred outside Hong Kong and should not have been assessed in HK at all. Our team performed a detailed back-calculation across three tax years, identifying the correct HK-sourced portion for each tranche.
We prepared amended BIR60 returns for three tax years with detailed DIPN 38 apportionment schedules, and engaged directly with the IRD's assessors to explain the methodology. The amended assessments were accepted without challenge. Simultaneously, we coordinated with the client's UK accountants to adjust the Foreign Tax Credit position in his HMRC Self Assessment returns, ensuring no double-recovery and optimal UK-side treatment.
French Executive Facing HK$2.1M Estimated Assessment — Resolved to HK$180,000
A French national serving as Regional Director for a luxury goods group departed Hong Kong to take up a Paris posting. His employer's HR department, unaware of the IR56G obligation, failed to file the departure clearance form before he left Hong Kong. Three months after departure, the IRD issued an estimated assessment for HK$2.1 million — based on assumed income with no deductions.
The client contacted us in a state of considerable alarm. We immediately filed a notice of objection to hold the assessment open, obtained a power of attorney to act as his authorised representative, and assembled the complete record: payslips, the Hong Kong entity's IR56B filings, his actual final-year income, and all available deduction receipts.
We prepared a comprehensive objection with supporting schedules showing the correct assessable income — including a proper computation of his departure-year salary (apportioned to the date of departure), his RSU vesting from that year (with DIPN 38 apportionment applied), and all personal allowances. The IRD accepted our submission and revised the assessment.

The Real Cost of Self-Filing Your Expat Tax Return
Many expats file their own returns for the first few years — and many pay significantly more tax than required as a result. Here is a direct comparison of what DIY filers typically miss and what professional representation costs versus saves.
| Tax Issue | DIY Self-Filer (Typical) | TAX.hk Representation | Typical Saving |
|---|---|---|---|
| RSU / Option apportionment (DIPN 38) | Reports 100% as HK-taxable — employer's IR56B figure used uncritically | Full DIPN 38 apportionment calculation; HK portion only assessed | HK$50K–HK$400K per year |
| Double Tax Treaty relief | DTA not claimed; tax paid in both HK and home country | Coordinated treaty election filed in both jurisdictions | HK$80K–HK$300K |
| Housing benefit structure | Accepts employer's structure; cash allowance taxed in full | Restructure to company lease; 10% cap applied under s.9(2A) | HK$100K–HK$250K per year |
| Departure clearance (IR56G) | Left entirely to HR; estimated assessment often raised after departure | Full management: brief employer, review IR56G, manage assessment | Avoid HK$500K–HK$2M+ estimated tax |
| Personal Assessment election | Election not made; property tax and salaries tax assessed separately at higher rate | Personal Assessment election made where beneficial; all income aggregated | HK$20K–HK$80K per year |
| Dependent allowances | Standard allowances only claimed; enhanced allowances overlooked | Full audit of all available allowances under IRO s.30–46 | HK$15K–HK$50K per year |
| IRD enquiry response | Handled by client directly; often insufficient documentation; penalties assessed | Professional response within required timeframes; full documentation provided | Avoid 10%–35% surcharges |
What Our Expat Clients Say
"I had been filing my own returns for three years, thinking it was straightforward. TAX.hk discovered that my employer had been incorrectly reporting my RSU vestings at 100% HK-sourced for every grant since my arrival. The correct DIPN 38 calculation brought my taxable amount down substantially — and I received a refund I had no idea was coming. The fee was a rounding error compared to the recovery."
"When I was transferred back to Paris, our Hong Kong HR team forgot to file the IR56G. I discovered this three months later when I received an estimated assessment for over HK$2 million — more than twice my actual Hong Kong income. TAX.hk took over immediately, filed the objection, and reduced the assessment to a number that actually matched what I had earned. I cannot recommend them highly enough."
"As a US citizen in Hong Kong, my tax situation is genuinely complicated — FBAR, Form 8938, Foreign Earned Income Exclusion, and now Hong Kong salaries tax on top. TAX.hk coordinates the whole picture. They speak directly with my US-side CPA, and the result is a coherent global strategy instead of two advisers who have never spoken to each other creating conflicts. Worth every dollar."
