A company enjoying corporate income tax incentives is sold at a premium — part of the price reflecting "taxes not payable" in coming years. The buyer's key question: after closing, do the incentives survive, or do they leave with the old owner?
The answer lies in one core principle: tax incentives attach to the investment project, not to the person who owns it — and they are not assets that can be bought or transferred independently.

1. Core principle: incentives attach to the project, not the owner
CIT incentives are granted by the State to investment projects meeting location (disadvantaged areas, industrial parks, economic zones…) or sector (high-tech, renewables, education, healthcare…) conditions — not to the individual owner. Consequences:
- Ownership changes while the project and legal person stay the same → incentive conditions remain met → incentives continue;
- Incentives cannot be "detached" from the project and sold separately;
- Any change leaving the project non-compliant → risk of losing incentives, reassessment, and penalties.
2. Company sale (capital transfer): incentives usually survive
For a pure capital/share transfer:
- The corporate legal person is unchanged (same enterprise code, same tax code);
- The investment project remains implemented by that same legal person, at the same location, in the same sector;
- Hence incentives in principle continue through their remaining term.
But "in principle" is not "certain". The buyer must check: remaining incentive period; maintenance conditions (capital scale, headcount, technology, environment) that post-M&A restructuring might breach; compliance history for any "stains".
3. Five cases of losing incentives in M&A
- Transferring the investment project to a new legal person without meeting incentive-succession conditions — incentives don't automatically "follow" the project to the new owner;
- Terminating or suspending the incentivized project post-M&A;
- Changing project objectives/scale so incentive conditions fail (e.g., shifting part to a non-incentivized sector);
- Mergers/consolidations changing the implementing legal person without an incentive-treatment plan;
- Breaching maintenance conditions during restructuring (cutting headcount below commitments, relocating…).
4. Incentives are not transferable assets
The most misunderstood point: treating tax incentives as intangible assets "bought" with the company. In substance:
- Incentives are State policy for qualifying projects — not independent property rights;
- They cannot be detached from the project for separate transfer;
- When the project moves to another legal person, continued incentives depend on succession rules — not automatic.
5. Tax due diligence: 6-area checklist
- ☐ Incentive decisions/certificates: preferential rates, holiday periods, remaining term
- ☐ Applicable eligibility conditions (location, sector)
- ☐ Maintenance conditions: capital, labor, technology, environment
- ☐ Compliance history: any reassessment/penalties for unmet conditions
- ☐ Whether incentives attach to a specific legal person; treatment upon legal-person changes
- ☐ Risks from the buyer's post-M&A restructuring plans
6. Allocating incentive risk in the SPA
Best practice in the SPA:
- Seller representations & warranties on incentive validity and compliance history;
- Price-adjustment or indemnity mechanisms if incentives are revoked/reassessed post-closing for pre-closing causes;
- Seller provides full incentive dossiers in the data room — concealing incentive-loss risks can breach warranties.
7. Notification/update duties to the tax authority
Ownership changes don't alter the tax code, but the enterprise must update tax registration information upon relevant changes. More importantly: post-M&A changes to the investment project, location, or business lines should be reviewed with the tax authority, as they may affect incentive conditions.
8. Three common mistakes
- Pricing the deal on incentives without checking remaining terms — nearly-expired incentives make the "taxes not payable" in the financial model illusory;
- Assuming incentives automatically follow the project when transferred to a new legal person;
- Post-M&A restructuring breaching maintenance conditions (headcount cuts, relocation) without assessing incentive impact.
9. FAQs
If 100% of a company's capital is sold, do CIT incentives survive? In principle, yes — for a pure capital/share transfer. Corporate income tax incentives attach to the investment project and the legal person implementing it; when only ownership changes while the legal person and project stay the same, location/sector conditions remain met and incentives continue. The buyer must still check: remaining incentive period, and maintenance conditions (capital, labor, technology) that post-M&A restructuring might breach.
When are tax incentives lost in M&A? High-risk cases: (1) transferring the investment project to a new legal person without meeting incentive-succession conditions; (2) terminating/suspending the incentivized project; (3) changing project objectives/scale so incentive conditions are no longer met; (4) mergers/consolidations changing the implementing legal person without an incentive-treatment plan; (5) breaching maintenance conditions (e.g., headcount commitments) during post-M&A restructuring.
Can tax incentives be 'transferred' to a new company? Tax incentives are not assets that can be bought or transferred independently — they attach to a specific investment project and a qualifying legal person. When the project moves to another legal person, continued incentives depend on succession rules for project transfers, not automatic carryover. This is the most misunderstood point among buyers.
What should tax due diligence cover on incentives in M&A? Minimum checklist: (1) incentive decisions/certificates and remaining periods; (2) applicable incentive conditions (rates, holidays, durations); (3) maintenance conditions (location, sector, capital, labor, technology, environment); (4) compliance history — any reassessment/penalties for unmet conditions; (5) whether incentives attach to a specific legal person; (6) incentive treatment under post-deal restructuring (merger/consolidation/division).
Must the seller disclose tax-incentive information to the buyer? No standalone statutory disclosure duty exists for tax incentives, but concealing incentive-loss risks can breach the seller's representations & warranties. Best practice: the seller provides full incentive dossiers in the data room; the SPA allocates risk if incentives are revoked after closing.
Must ownership changes be notified to the tax authority? Ownership changes (capital transfers) do not change the enterprise's tax code, but the enterprise must update tax registration information upon relevant changes. More importantly, post-M&A changes to the investment project, location, or business lines may affect incentive conditions and should be reviewed with the tax authority.
10. When to work with counsel
Tax incentives often form a significant share of M&A valuation — mishandled, the buyer may face major reassessments and penalties post-closing. Work with counsel (together with tax advisors) for: (i) incentive tax due diligence; (ii) assessing deal-structure impact on incentives; (iii) drafting risk-allocation clauses in the SPA; (iv) engaging the tax authority on incentive succession/continuation.
