Key Facts: Stamp Duty for Startups Raising Capital
- No stamp duty on new share issuance: Hong Kong abolished capital duty in 2012 – raising capital through new shares incurs zero stamp duty
- 0.2% duty on share transfers: Existing shares transferred between parties attract 0.2% total stamp duty (0.1% each for buyer and seller)
- Rate reduction in effect: Stamp duty was reduced from 0.26% to 0.2% on November 17, 2023, making equity transactions more affordable
- Group relief available: Intra-group transfers can qualify for exemptions under Section 45 SDO, but only for companies with issued share capital (post-June 2025 ruling)
- No capital gains tax: Hong Kong has no capital gains tax, enhancing the attractiveness of equity investments
- Strategic planning essential: Structure your capital raising correctly to minimize or eliminate stamp duty costs
Stamp Duty Exemptions for Startups Raising Capital in Hong Kong
For startups navigating Hong Kong’s funding landscape, understanding stamp duty implications can mean the difference between preserving precious capital and incurring unnecessary costs. This comprehensive guide explains how Hong Kong’s stamp duty regime affects capital raising, which structures qualify for exemptions, and how to optimize your funding strategy for maximum tax efficiency.
Understanding Hong Kong’s Stamp Duty Framework
Hong Kong’s stamp duty regime distinguishes clearly between two fundamentally different transactions: issuing new shares (capital raising) and transferring existing shares (secondary transactions). This distinction is critical for startups planning their funding rounds.
The Golden Rule: New Shares vs. Share Transfers
Since 2012, Hong Kong has operated a startup-friendly capital duty regime that completely exempts new share issuances from stamp duty. This means when your company raises capital by issuing fresh shares to investors, no stamp duty is payable.
However, if existing shareholders sell their shares to new or existing investors (a secondary transaction), stamp duty applies at the current rate of 0.2% of the transaction value, split equally between buyer and seller (0.1% each).
| Transaction Type | Stamp Duty Rate | Who Pays | Timing Requirement |
|---|---|---|---|
| New Share Issuance (Capital raising/allotment) |
0% (No stamp duty) |
N/A | N/A |
| Share Transfer (Sale of existing shares) |
0.2% (0.1% buyer + 0.1% seller) |
Both transferor and transferee | Within 30 days for offshore transactions; 2 days for local sales |
| Intra-Group Transfer (Section 45 relief) |
0% (If qualifying conditions met) |
N/A | Application required; clawback provisions apply |
| Stock Borrowing/Lending | 0% (Exempt) |
N/A | Must meet qualifying criteria |
2023 Rate Reduction: A Win for the Ecosystem
On November 17, 2023, Hong Kong reduced the stamp duty rate on share transfers from 0.26% to 0.2% (from 0.13% to 0.1% per party). This 23% reduction makes secondary transactions more affordable and demonstrates the government’s commitment to maintaining Hong Kong’s competitiveness as a financial hub.
Capital Raising Strategies: Optimizing for Stamp Duty
Scenario 1: Seed Round – Pure New Money
Example: TechStart HK Limited raises HKD 5 million in seed funding
- Current shareholding: 2 founders holding 5,000,000 shares @ HKD 1 par value
- Investment structure: Issue 1,250,000 new shares @ HKD 4 per share to VC fund
- Post-money valuation: HKD 25 million
- VC ownership: 20%
Stamp Duty Payable: HKD 0
Because this is a new share issuance, no stamp duty applies regardless of the amount raised.
Scenario 2: Series A with Founder Partial Exit
Example: Growing startup raises HKD 30 million Series A
- Primary investment (new shares): HKD 25 million – 0% stamp duty
- Secondary sale (founder shares): HKD 5 million – 0.2% stamp duty
Stamp Duty Payable: HKD 10,000
Calculation: HKD 5,000,000 × 0.2% = HKD 10,000 (split: HKD 5,000 paid by selling founder, HKD 5,000 by purchasing investor)
Scenario 3: Late-Stage Pre-IPO Round
Example: Pre-IPO company raises HKD 200 million
- Structure: 100% new share issuance to institutional investors
- Pre-money valuation: HKD 800 million
- Post-money valuation: HKD 1 billion
Stamp Duty Payable: HKD 0
Strategic decision to issue only new shares saves HKD 400,000 in stamp duty compared to a secondary transaction structure.
Section 45 Stamp Duty Relief: Intra-Group Transfers
Section 45 of the Stamp Duty Ordinance provides valuable relief for corporate restructuring and group reorganizations – common scenarios as startups scale and institutionalize their structures.
Qualifying Conditions
To qualify for Section 45 relief, the following requirements must be met:
- 90% Association Test: One company must beneficially own at least 90% of the issued share capital of the other, OR a third company must own at least 90% of both companies
- Bodies Corporate Only: Following the June 2025 Court of Final Appeal ruling, relief applies ONLY to companies with issued share capital – LLPs, LLCs, and similar structures do not qualify
- Hong Kong Stock: The shares being transferred must be “Hong Kong stock” (shares requiring registration in Hong Kong)
- Clawback Period: The 90% association must be maintained for 2 years post-transfer, or relief will be clawed back
⚠️ Important 2025 Legal Development
The Court of Final Appeal ruled in June 2025 that Section 45 relief is only available to companies with issued share capital. This means that increasingly popular structures like Limited Liability Partnerships (LLPs) and Limited Liability Companies (LLCs) used by private equity and venture capital funds may not qualify for relief.
Impact for Startups: If your investors use LLP or LLC structures, intra-group transfers involving your shares may not qualify for stamp duty relief. This should be considered in shareholder agreements and restructuring plans.
Practical Application for Startups
| Restructuring Scenario | Section 45 Relief Available? | Key Considerations |
|---|---|---|
| Creating a holding company structure (HoldCo owns 100% of OpCo) | ✓ Yes | Both entities must be companies with share capital; maintain 90%+ ownership for 2 years |
| Transferring shares to a Limited Partnership Fund (LPF) | ✗ No | LPF is not a body corporate with share capital (per 2025 CFA ruling) |
| Sister company share transfers (both 100% owned by parent) | ✓ Yes | Parent must own 90%+ of both companies; all must have share capital |
| Pre-IPO restructuring into variable interest entity (VIE) | ⚠ Depends | Structure-specific analysis required; professional advice essential |
IPO Pathway: GEM vs. Main Board Considerations
For startups eyeing a Hong Kong Stock Exchange listing, understanding the stamp duty implications of different listing pathways is essential.
Stock Exchange Trading: Ongoing Stamp Duty
Once listed on either GEM (Growth Enterprise Market) or the Main Board, all secondary market transactions in your shares will attract stamp duty at 0.2% per transaction. This is an unavoidable cost of trading on the Hong Kong Stock Exchange.
However, the stamp duty regime does not distinguish between GEM and Main Board listings – the same 0.2% rate applies to both markets.
Pre-IPO Planning: Treasury Shares
Following amendments to the Hong Kong Stock Exchange Listing Rules effective June 11, 2024, listed issuers can now hold and resell treasury shares. This development has important stamp duty implications:
- Repurchase of shares: Subject to normal 0.2% stamp duty when buying back from market
- Resale of treasury shares: Subject to ad valorem stamp duty under the Stamp Duty Ordinance when resold
- Share scheme grants: Treasury shares used for employee share schemes are treated the same as new share issuances for stamp duty purposes
GEM to Main Board Transfer
Startups that initially list on GEM may later transfer to the Main Board as they mature. The transfer process itself does not trigger stamp duty on existing shares, as no change of beneficial ownership occurs. However, any share transactions executed as part of the transfer process (e.g., selling down cornerstone investors) would be subject to the standard 0.2% stamp duty.
Venture Capital and Private Equity: Fund Structure Matters
The structure of your investors can significantly impact stamp duty efficiency – not just at the initial investment stage, but throughout the life of the investment relationship.
Limited Partnership Funds (LPFs): The Preferred VC/PE Structure
Since the introduction of the Limited Partnership Fund Ordinance in August 2020, Hong Kong has offered a highly competitive fund structure for venture capital and private equity investors. LPFs offer significant advantages:
| LPF Advantage | Stamp Duty Impact | Benefit for Startups |
|---|---|---|
| Tax transparency | No stamp duty on transfers of LP interests (partnership interests are not “Hong Kong stock”) | LPs can trade fund interests without triggering duty on underlying portfolio companies |
| 0% profits tax (if qualifying) | Enhances after-tax returns, but doesn’t directly affect stamp duty | More capital available for investment and follow-on funding |
| Flexible structuring | BUT: Cannot benefit from Section 45 relief (per 2025 ruling) | Mixed implications – good for LP transfers, challenging for restructuring |
Corporate VC Structures
Corporate venture capital arms structured as regular companies (with share capital) have different stamp duty implications:
- Initial investment: 0% stamp duty if investing via new share issuance
- Secondary purchases: 0.2% stamp duty on acquisitions of existing shares
- Intra-group restructuring: Can benefit from Section 45 relief if qualifying conditions are met
- Exit via trade sale: 0.2% stamp duty on share transfer (if selling Hong Kong company shares)
2025 Tax Scrutiny: Compliance Matters
⚠️ Increased IRD Scrutiny on PE/VC Funds
In May 2025, reports emerged that Hong Kong authorities are intensifying tax checks of private equity and venture funds. While this primarily concerns profits tax and fund management activities, it underscores the importance of maintaining meticulous stamp duty compliance.
Action for Startups: Ensure all share transfer documents are properly stamped within statutory deadlines. Late stamping penalties can reach up to 10× the duty amount for delays exceeding 2 months.
Family Offices and Strategic Investors: Emerging Opportunities
Hong Kong’s aggressive push to attract family offices creates unique opportunities for startups seeking strategic capital with favorable tax treatment.
Family Office Tax Concession Framework
Eligible Single Family Offices (ESFOs) managing Family-owned Investment Holding Vehicles (FIHVs) can benefit from 0% profits tax on qualifying investments, including startup investments. Key parameters:
- Asset threshold: Minimum HKD 240 million assets under management
- Operating requirements: Minimum 2 full-time qualified employees; HKD 2 million annual operating expenditure in Hong Kong
- Ownership: 95% owned by a single family (charitable organizations can own up to 25%)
- 2025-2026 enhancements expected: Government contemplating further concessions; legislative proposals expected in 2026
Stamp Duty Implications for Startup Investments
When family offices invest in your startup:
| Investment Method | Stamp Duty Treatment | Additional Tax Benefits |
|---|---|---|
| Direct investment via new share issuance | 0% stamp duty | FIHV may enjoy 0% profits tax on gains if qualifying |
| Secondary purchase from existing shareholders | 0.2% stamp duty | FIHV may enjoy 0% profits tax on future gains if qualifying |
| Investment through fund-of-funds structure | Depends on structure; fund interests may not attract stamp duty | Multiple layers of tax efficiency possible |
Capital Investment Entrant Scheme (CIES): New Capital Flows
Since March 2024, the new CIES has enabled high-net-worth individuals to obtain Hong Kong residency through HKD 27 million+ investments in qualifying assets. Starting March 2025, investments through eligible privately-held companies owned entirely by the applicant also qualify.
This creates new pools of capital for startups, particularly in sectors aligned with CIES investment portfolios. Stamp duty treatment follows the same principles: new share issuances attract no duty, secondary transactions attract 0.2% duty.
Compliance and Penalties: Critical Timing Requirements
Understanding when and how to stamp documents is just as important as understanding the duty rates themselves.
Stamping Deadlines
| Transaction Location | Stamping Deadline | Document Required |
|---|---|---|
| Local sale (executed in Hong Kong) | 2 days from execution | Instrument of transfer / bought and sold notes |
| Offshore transaction | 30 days from execution | Instrument of transfer / contract note |
| New share issuance | N/A (no stamping required) | Board resolutions and updated register of members (not stamped) |
Late Stamping Penalties
The Inland Revenue Department imposes severe penalties for late stamping:
- Less than 1 month late: Up to 2× the stamp duty
- 1 to 2 months late: Up to 4× the stamp duty
- More than 2 months late: Up to 10× the stamp duty
Example: A share transfer valued at HKD 10 million stamped 3 months late
- Normal stamp duty: HKD 20,000 (0.2% of HKD 10 million)
- Maximum penalty: HKD 200,000 (10× duty for delays exceeding 2 months)
- Total potential cost: HKD 220,000
The penalty is 11× the cost of timely compliance!
Valuation for Stamp Duty Assessment
The Inland Revenue Department assesses stamp duty on the higher of:
- Stated consideration: The amount actually paid for the shares
- Market value: The IRD’s assessment of fair market value
For startups, valuation methodologies vary:
- Listed companies: Closing price on the last trading day before transfer
- Private companies: Generally Net Asset Value (NAV) from latest audited accounts, though IRD may request additional valuation support
- Early-stage startups: Recent funding round valuations often accepted, but IRD may challenge artificially low valuations in related-party transactions
Strategic Planning Checklist for Startups
Optimize your capital raising structure with these stamp duty considerations:
Pre-Funding Round
- ✓ Structure investments as new share issuances rather than secondary transfers wherever possible
- ✓ If founders need liquidity, minimize the secondary component and price it realistically to avoid IRD challenges
- ✓ Verify that your company’s authorized share capital is sufficient for the proposed issuance
- ✓ Prepare board resolutions and shareholder approvals for share issuance
- ✓ If investors use LLP/LLC structures, understand they won’t qualify for Section 45 relief in future restructuring
During Investment Execution
- ✓ Clearly document whether transactions are primary (new shares) or secondary (existing shares)
- ✓ For any secondary transactions, identify buyer and seller stamp duty obligations in transaction documents
- ✓ Ensure share transfer instruments are executed properly with all required signatures
- ✓ Submit stamping documents to IRD within statutory deadlines (2 days for local, 30 days for offshore)
- ✓ Pay the HKD 5 per transfer document fee in addition to ad valorem duty
Post-Funding
- ✓ Update the register of members to reflect new shareholdings
- ✓ File the return of allotment with the Companies Registry (Form NSC1) within 1 month
- ✓ Retain stamped documents and payment receipts for IRD audit purposes
- ✓ If you claimed Section 45 relief, diarize the 2-year clawback period and monitor association requirements
- ✓ Brief your legal and finance teams on stamp duty obligations for any future share transactions
Pre-Exit Planning
- ✓ Model stamp duty costs for different exit scenarios (trade sale vs. IPO vs. secondary sale)
- ✓ For IPO path, understand that all post-listing trading will attract 0.2% stamp duty
- ✓ Consider restructuring options and assess Section 45 relief eligibility well in advance
- ✓ Engage tax advisors early to optimize structure and timing
Comparison with Regional Competitors
How does Hong Kong’s stamp duty regime compare with other major Asian startup hubs?
| Jurisdiction | New Share Issuance | Share Transfer | Capital Gains Tax |
|---|---|---|---|
| Hong Kong | 0% | 0.2% | 0% |
| Singapore | 0% | 0.2% | 0% (generally) |
| China (Mainland) | 0% | 0.1% | 20% (individual) / varies (corporate) |
| Taiwan | 0.1% | 0.3% | 20% (individual) / 20% (corporate) |
| Japan | 0.7% (of capital increase) | 0% (unlisted) / varies (listed) | 20.315% (individual) / ~30% (corporate) |
Key Takeaway: Hong Kong’s 0% stamp duty on new share issuances and 0% capital gains tax create a highly competitive environment for startup funding, particularly when compared with Northeast Asian markets. The stamp duty rate on share transfers matches Singapore but is higher than mainland China – however, the absence of capital gains tax more than compensates.
Common Pitfalls and How to Avoid Them
Pitfall 1: Structuring as Secondary When Primary is Possible
Problem: Founders negotiate a HKD 50 million Series B where existing shareholders sell HKD 10 million of their holdings.
Cost: HKD 20,000 in unnecessary stamp duty (HKD 10 million × 0.2%)
Solution: Unless founders genuinely need liquidity, structure the entire round as new share issuance. If liquidity is needed, minimize the secondary component or defer it to a later round when valuations may be higher (making the same absolute liquidity amount require transferring fewer shares).
Pitfall 2: Ignoring Stamping Deadlines
Problem: Founders complete a share transfer but forget to submit stamping documents, discovering the issue 6 months later during a due diligence process.
Cost: Up to 10× penalty multiplier plus potential due diligence red flags
Solution: Include stamp duty compliance in your investment closing checklist. Assign a specific team member (typically legal counsel or CFO) responsibility for ensuring timely stamping. Use calendar reminders for the 2-day (local) or 30-day (offshore) deadlines.
Pitfall 3: Claiming Section 45 Relief for Ineligible Structures
Problem: A startup attempts to claim Section 45 relief for transferring shares to a Limited Partnership Fund, unaware of the June 2025 Court of Final Appeal ruling.
Cost: Relief claim rejected; duty payable plus potential penalties and interest
Solution: Before claiming Section 45 relief, verify that BOTH the transferor and transferee are bodies corporate with issued share capital. Engage professional tax advisors for complex structures. Keep detailed documentation supporting the 90% association requirement.
Pitfall 4: Undervaluing Shares in Related-Party Transactions
Problem: A founder transfers shares valued at HKD 5 million to a family trust for stated consideration of HKD 1 million to minimize stamp duty.
Cost: IRD assesses duty on HKD 5 million market value anyway, plus potential penalties for undervaluation
Solution: The IRD assesses duty on the higher of consideration or market value. Don’t attempt to artificially reduce stamp duty through undervaluation – it won’t work and creates compliance risks. For related-party transactions, use supportable market valuations based on recent funding rounds or independent valuations.
Pitfall 5: Exceeding Authorized Share Capital
Problem: A company with 10 million authorized shares attempts to issue 2 million new shares when it already has 9 million shares outstanding.
Cost: Share issuance is void; deal may be delayed while authorized share capital is increased
Solution: Before finalizing funding terms, verify available authorized share capital. If insufficient, pass a special resolution to increase authorized share capital BEFORE attempting the share issuance. Note: While Hong Kong has no stamp duty on share issuances, you must have adequate authorized share capital to complete the transaction legally.
Future Outlook: Potential Reforms and Trends
Government Signals on Stamp Duty Policy
Several developments suggest Hong Kong may further refine its stamp duty regime:
- Family office enhancements: The government has signaled enhancements to tax concessions for family offices, with legislative proposals expected in 2026
- Section 45 reform needed: The Court of Final Appeal explicitly noted that “reform of the law is required” to address modern corporate structures like LLPs and LLCs
- Competitive pressure: As regional competitors (particularly Singapore and Dubai) aggressively court startups and funds, Hong Kong may introduce additional incentives
- Stock market liquidity: The November 2023 stamp duty reduction from 0.26% to 0.2% was explicitly aimed at enhancing market competitiveness – further reductions remain possible if trading volumes don’t recover
Best Practices for Future-Proofing
While we can’t predict future regulatory changes, startups can position themselves to benefit from potential reforms:
- Maintain clean cap tables: Well-documented shareholding structures make it easier to adapt to regulatory changes
- Build relationships with sophisticated investors: Family offices, qualified LPFs, and other investors with tax-optimized structures often have flexibility to adapt to new incentives
- Stay informed: Monitor InvestHK, the Companies Registry, and IRD announcements for policy updates
- Engage professional advisors: Tax and legal advisors can help you navigate changes and identify new opportunities as they emerge

When to Engage Professional Advisors
While many stamp duty matters are straightforward, consider engaging tax and legal professionals when:
- Funding rounds exceed HKD 10 million (professional fees will be marginal relative to deal size and potential duty savings)
- Your investor base includes complex structures (LPFs, family offices, corporate VCs with group structures)
- You’re planning corporate restructuring or intra-group transfers
- Secondary transactions form a significant portion of a funding round
- You’re approaching an IPO and need comprehensive tax planning
- You’ve missed stamping deadlines and need to regularize compliance
- The IRD has raised questions or queries about your stamp duty filings
Online Stamp Duty Calculation and Filing
The IRD offers an e-stamping service (eTax platform) that allows you to:

Key Takeaways: Maximizing Stamp Duty Efficiency
- Structure for Success: Always prioritize new share issuances over secondary transfers when raising capital. The 0% stamp duty on new shares (versus 0.2% on transfers) can save tens or hundreds of thousands of Hong Kong dollars as your startup scales.
- Timing is Critical: Stamp duty documents must be submitted within 2 days (local transactions) or 30 days (offshore transactions). Late stamping penalties can reach 10× the duty amount – compliance is far cheaper than remediation.
- Investor Structure Matters: The June 2025 Court of Final Appeal ruling means that only companies with issued share capital can benefit from Section 45 group relief. If your investors use LLP or LLC structures, plan accordingly for future restructuring needs.
- No Capital Gains Tax Advantage: Hong Kong’s absence of capital gains tax, combined with 0% stamp duty on new share issuances, creates one of Asia’s most favorable environments for startup funding and investor returns.
- Professional Guidance Pays Dividends: For funding rounds above HKD 10 million or involving complex structures, professional tax and legal advice typically costs a small fraction of potential duty savings and compliance risk mitigation.
- Family Offices and LPFs: Hong Kong’s enhanced tax concessions for family offices and the Limited Partnership Fund regime create sophisticated investor structures with favorable tax treatment – but understand their stamp duty implications in your cap table planning.
- IPO Considerations: If your exit strategy involves a Hong Kong listing, remember that all post-IPO trading will attract the 0.2% stamp duty. Factor this into liquidity planning and investor expectations.
- Regional Competitiveness: Hong Kong’s stamp duty regime is highly competitive with Singapore and substantially more favorable than Northeast Asian alternatives (Taiwan, Japan) when considering the combined effect of stamp duty, capital duty, and capital gains tax.
- Future Reforms Expected: Watch for potential enhancements to family office concessions (legislative proposals expected in 2026) and possible Section 45 reforms to accommodate modern fund structures.
- Documentation Excellence: Maintain meticulous records of all share transactions, stamping certificates, and supporting valuations. Clean documentation is essential for future funding rounds, M&A due diligence, and IRD audits.
