Tax Filing Guide 2026:
7 Most Overlooked Deductions
Gary Chung（FinKit Editor-in-Chief） · Published：July 29, 2026
Every tax season, many Hong Kong employees simply fill out their BIR60 and consider it done, never checking whether they've exhausted all available allowances and deductions. According to IRD data, a large number of taxpayers miss at least one deductible item each year — and combined, these items can save you thousands or even tens of thousands in tax. This guide compiles the 7 most commonly missed deductions for the 2026 tax year, with full amounts, eligibility criteria, and deadlines.
2026 Tax Year Quick Reference
The tax year (year of assessment) runs from 1 April to 31 March of the following year. The following applies to the 2025/26 year of assessment (i.e., the tax return you receive in May–June 2026):
| Deduction | Annual Cap | Eligible For | Common Reason for Missing |
|---|---|---|---|
| 1. VHIS Premium | $8,000/person insured | Taxpayer, spouse, children, parents | Thought company insurance was enough; didn't buy separately |
| 2. MPF TVC | $60,000 | Anyone with an MPF account | Confused with regular MPF contributions; didn't know TVC is separately deductible |
| 3. Rent Deduction | $100,000 | Tenants who don't own residential property | Didn't know this was introduced in 2022 |
| 4. Dependent Parent/Grandparent | $25,000–$50,000 each | Living together or not | No coordination among siblings; duplicate claims |
| 5. Self-Education Expenses | $100,000 | Enrolled in designated courses | Unsure which courses qualify |
| 6. Charitable Donations | 35% of assessable income | Anyone | Didn't keep receipts |
| 7. Home Loan Interest | $100,000 | Homeowner with mortgage | Didn't know it's deductible for up to 15 years |
1. VHIS Deduction: Premiums for Your Parents Count Too
Since its launch in 2019, the Voluntary Health Insurance Scheme (VHIS) has allowed annual premium deductions — and premiums for your spouse, children, and parents all count.
Deduction Amount
Annual premium deduction cap per insured person: HK$8,000. If you've bought VHIS for yourself, your spouse, and both parents (4 people total), the maximum deduction could be 4 × $8,000 = $32,000.
Assuming your marginal tax rate is 17%, a $32,000 deduction = actual tax saved of $5,440. For employees in the highest tax bracket (17%), this is the most direct way to save tax.
⚠️ Common Pitfalls
- Only certified VHIS plans are deductible — regular medical insurance does not qualify
- You must have paid the premiums yourself — company health insurance doesn't count
- The parent must be a Hong Kong resident holding a HKID card
- The deduction is based on the policy year, not the tax year — match against the policy effective date
In your tax return, carefully enter the actual premiums paid for each insured person under the "VHIS Premium Deduction" section (don't just fill in $8,000 — enter the real figure; the IRD will apply the cap automatically).
2. MPF TVC: Save Up to $10,200 in Tax
Many people confuse MPF TVC (Tax-Deductible Voluntary Contributions) with regular mandatory MPF contributions. Regular MPF contributions (employee 5% + employer 5%) are already deducted when calculating assessable income — no additional claim is needed. But TVC is an additional voluntary contribution that is independently tax-deductible.
Deduction Amount
Annual cap: HK$60,000. At the highest marginal rate of 17%, maximum tax saved = $60,000 × 17% = $10,200.
But note: money contributed to TVC, like mandatory MPF, can only be withdrawn at age 65 (unless meeting specific conditions such as permanent departure from Hong Kong or total incapacity). So TVC is a decision to trade liquidity for tax benefits.
Who should consider TVC? Higher-income employees in the 17% tax bracket. Contributing $60,000 a year to TVC immediately saves $10,200 in tax — a guaranteed 17% "return." In today's environment where bank fixed deposits yield only 3–4%, TVC's tax rate of return outperforms any low-risk investment.
3. Rent Deduction: Introduced in 2022, Still Widely Overlooked
The residential rent deduction was only introduced in the 2022/23 year of assessment, and many people still don't know it exists. As long as you're a tenant who does not own residential property in Hong Kong and rent a residential unit under a tenancy agreement, you can claim this deduction.
Deduction Amount
Annual cap: HK$100,000 (approximately $8,333 per month). At the 17% rate, maximum tax saved = $17,000.
Crucially, married couples filing jointly can each claim separately, as long as both meet the condition of not owning property. If both spouses rent together, each can deduct $100,000, combined cap $200,000 — a substantial difference if your rent is high enough.
⚠️ Eligibility Requirements
- The tenancy agreement must be stamped — unstamped leases are ineligible
- Landlord and tenant must not be related (parents renting to children doesn't count)
- If you receive a housing allowance from your employer, you cannot use the rent deduction
- The lease period must cover time within the tax year
4. Dependent Parent/Grandparent Allowance: $10,000 More If Living Together
The dependent parent allowance is the item where family internal conflicts happen most. Multiple children can claim the same parent, but the IRD will only approve one — without coordination among siblings, all claims get rejected.
| Scenario | Annual Allowance (per person) | Additional Conditions |
|---|---|---|
| Parent/grandparent aged 55–59 (not living together) | $25,000 | No cohabitation required |
| Parent/grandparent aged 55–59 (living together) | $50,000 | Living together for full year, continuous not required |
| Parent/grandparent aged 60+ (not living together) | $50,000 | No cohabitation required |
| Parent/grandparent aged 60+ (living together) | $100,000 | Full year cohabitation + age 60+ = double bonus |
If your parents are 60+ and living with you, the allowance can reach $100,000 per person. Supporting two 60+ parents living together = $200,000 allowance, saving $34,000 in tax at the 17% rate.
How should siblings coordinate? The simplest approach: discuss before each tax season and agree who claims which parent. If multiple children support the parents, you can agree to "rotate" claims (e.g., elder brother claims this year, younger sister next year).
5. Self-Education Expenses: Not Just University — Professional Exams Count Too
The self-education expense deduction is one of the most misunderstood items. As long as the course is taken to gain or maintain qualifications required for employment, the fees are deductible.
Deduction Amount
Annual cap: HK$100,000. At the 17% rate, maximum tax saved = $17,000.
Qualifying courses:
- Degree or diploma programmes at universities/tertiary institutions
- Exam prep courses and exam fees for professional qualifications (CFA, CPA, ACCA, FRM, PMP, etc.)
- Courses offered by educational institutions designated under the Inland Revenue Ordinance
- Skills training related to your current job (e.g., IT professional taking cloud certification courses)
Not eligible: courses taken purely out of interest (learning Japanese, cooking classes), or training unrelated to your current job. The IRD assesses whether the course is "necessary for gaining or maintaining employment" — if you're switching careers to learn something new, it usually doesn't count until you pass the qualification exam.
6. Charitable Donations: Up to 35% of Income
This is the simplest yet most frequently missed deduction. As long as you donate to tax-exempt charities (e.g., Oxfam, Orbis, The Community Chest, Tung Wah Group of Hospitals, etc.), the donation amount is deductible.
Deduction Amount
The deduction cap is 35% of your assessable income. The minimum donation amount for a claim is $100.
⚠️ Most Common Reason for Failure: No Receipts
- The IRD may request original donation receipts during an audit — keep them even for monthly donations
- Flag day purchases and street donations without receipts do not count
- The charity must be registered in Hong Kong — overseas charities (e.g., Wikipedia) are not eligible
- Donations to political organisations do not count
Develop a habit: at the start of each year, organise all donation receipts from the past year and scan digital copies. For monthly donations, ask the charity to issue an annual donation statement at year-end for easier one-time filing.
7. Home Loan Interest: A Must-Use for Homeowners
If you're the mortgagor of a self-occupied property, the interest portion of your annual mortgage payments is tax-deductible — and you can claim it for up to 15 consecutive years of assessment (they don't need to be consecutive; you can pick which years to use).
Deduction Amount
Annual cap: HK$100,000. This is the actual mortgage interest paid, not the total repayment amount. At the 17% rate, maximum tax saved = $17,000.
Example calculation:
Assuming a mortgage of $5,000,000, interest rate 4.125%, 30-year term:
- Annual interest paid: approximately $204,000 (first year)
- Deductible interest: $100,000 (capped)
- Tax saved: $100,000 × 17% = $17,000
- 15-year cumulative tax saved: up to $255,000
Important: only the interest portion is deductible — principal repayments don't count. And it must be a self-occupied property — mortgage interest for rental properties is claimed under Property Tax, not here.
Combining the 7 Deductions: A Real Tax-Saving Case
Here's a real Hong Kong employee example showing how to combine the above deductions:
Case: Monthly salary $50,000 employee (married, one child, supporting a 63-year-old mother living together)
Deductions
Net chargeable income is negative = no tax payable at all. Without maximising deductions, chargeable income would be approximately $56,000, with about $1,120 in tax. After using all available deductions, not only is there no tax to pay, but excess allowances can be transferred to a spouse (if they have chargeable income) for even more savings.
Tax Filing Timeline: Don't Miss Deadlines
| Time | Event | Note |
|---|---|---|
| Early May | IRD sends out tax returns (BIR60) | Check your mailbox; notify IRD immediately if lost |
| Early June | Tax return filing deadline | Usually 1 month; e-filing extends by 1 month |
| Aug–Dec | Notices of assessment gradually received | Check for errors; object within 1 month if incorrect |
| Jan (following year) | Pay first instalment of tax | Can apply for instalment payment |
| Apr (following year) | Pay second instalment of tax | Includes provisional tax for next year |
Using eTax for online filing has two major advantages: the deadline is automatically extended by one month, and the system calculates your tax for you — no risk of arithmetic errors.
FAQ
Q: Can I claim both the rent deduction and home loan interest deduction at the same time?
A: No. They are mutually exclusive — you must choose one. If you simultaneously rent and own a self-occupied property, you can only pick one deduction. General advice: go with the larger amount.
Q: What's the difference between TVC and regular MPF voluntary contributions?
A: There are three types of MPF contributions: (1) Mandatory contributions (employee 5% + employer 5%); (2) Regular voluntary contributions (not tax-deductible, but more flexible withdrawal); (3) TVC (tax-deductible, but only withdrawable at age 65). Only (3) is tax-deductible.
Q: Can VHIS premiums for siblings be deducted?
A: No. VHIS deduction only applies to: the taxpayer, spouse, children, and the taxpayer's or spouse's parents/grandparents. Siblings are not included.
Q: If I missed a deduction from last year, can I claim it retroactively?
A: Yes. You can object in writing within one month of receiving the notice of assessment, or submit Form IR831 to apply for a revised assessment. Generally, you can seek amendments going back up to 6 years.
Q: Dependent parent allowance — can I claim it if my parent has income?
A: It depends on how much the parent earns. The parent's annual income must not exceed the prescribed limit (approximately $36,000/year for 2025/26). Government allowances such as the Old Age Living Allowance and Old Age Allowance are not counted as income.
