⚠ Hidden Tax Liabilities Can Survive Completion
When you buy shares, you buy the company's entire tax history — including undisclosed assessments, disputed deductions, and transfer pricing risks. Tax due diligence protects you from inheriting the seller's tax problems.
Common Challenges
Share Deal vs Asset Deal
Share deals preserve the target's tax history (good and bad); asset deals start fresh but trigger stamp duty on each asset transferred. The optimal structure depends on both sides' tax position.
⚠ Risk: Wrong structure → unexpected stamp duty or inherited tax liabilities
Tax Due Diligence
Target companies may have unfiled returns, disputed assessments, aggressive deduction claims, or transfer pricing exposures that survive the acquisition.
⚠ Risk: No due diligence → buyer inherits seller's tax problems
Deferred Tax Assets
Acquired companies often have unused tax losses. Whether these can be carried forward and used by the acquirer depends on continuity of business rules under s.19C IRO.
⚠ Risk: Losses wasted → overpaying tax on post-acquisition profits
Purchase Price Allocation
How the acquisition price is allocated between assets (goodwill, inventory, property, equipment) affects future depreciation and capital allowance claims.
⚠ Risk: Poor allocation → suboptimal capital allowance position post-acquisition

Case Studies
HK retail group acquisition — due diligence saves deal
- •Target had 3 years of unfiled employer returns
- •IRD field audit in progress not disclosed
- •Purchase price adjusted by HKD 4.2M based on DD findings
- •Indemnity obtained for all pre-completion tax risks
“Without the due diligence, we would have bought someone else's tax nightmare.”
PE buyout — stamp duty saving on property-heavy target
- •Asset deal restructured to share deal via spin-off
- •Property stamp duty (HKD 1.6M) avoided
- •Tax losses of target preserved for use
- •Group structure optimised post-completion
“Restructuring the deal saved more than our entire advisory fee.”
Frequently Asked Questions
What is the stamp duty on a share deal vs asset deal in HK?
Share transfers attract HK stamp duty of 0.2% of consideration (0.1% buyer + 0.1% seller). Asset deals involving HK property attract stamp duty of up to 4.25% of the property value. For asset deals involving only trading stock or equipment (no property), no stamp duty applies — making asset deals potentially cheaper than share deals when the target has significant property.
Can I carry forward the acquired company's tax losses?
Tax losses of an acquired company can be used by the acquirer only if there is continuity of business — the same or substantially the same business must continue after the acquisition. Losses are also restricted if there is a change in shareholding (s.19C IRO). We assess loss utilisation as part of deal structuring.
What should I look for in a tax due diligence report?
Key items include: outstanding or estimated assessments, unfiled returns, disputes with IRD, aggressive deduction claims (R&D, offshore), transfer pricing exposures, employee misclassification (contractor vs employee), stamp duty on prior transactions, and any tax clearance correspondence.
Is there stamp duty relief for group restructuring transactions?
Yes. Section 45 of the Stamp Duty Ordinance provides relief for transfers of shares or property between associated bodies corporate (90% common ownership), subject to the relief not being withdrawn within 2 years if the relationship breaks down. This can significantly reduce the stamp duty cost of group restructuring.
How is goodwill treated for tax purposes in an acquisition?
Goodwill acquired in a business acquisition is NOT deductible for HK profits tax purposes (it's a capital expenditure). Only if the goodwill relates to a customer list or know-how that is separately identified and used in the business — and it qualifies as depreciated cost under s.16G or 16B — may a deduction arise.
What tax warranties should I negotiate in the SPA?
Key tax warranties include: accuracy of all filed returns, no outstanding assessments or disputes, arm's length related party transactions, correct PAYE/MPF treatment, no obligation to make good any prior tax indemnity, and full disclosure of any DIPN-listed items. We draft or review these in the SPA negotiation.
