When considering closing or transferring a clinic, we often receive inquiries about whether to sell as an individual practitioner or after incorporating as a medical corporation. This decision significantly impacts the M&A structure, tax burden, procedural complexity, and the final net proceeds. Therefore, careful consideration from an early stage is essential. This article provides a multi-faceted comparison of M&A for individual practitioners versus medical corporations, detailing key discussion points and specific processes to help you find the optimal choice.
Fundamental Differences in M&A Schemes: Individual Practice vs. Medical Corporation
The M&A schemes employed for individual medical practices and medical corporations differ significantly. For the sale of an individually operated clinic, the general approach is a “business transfer.” This involves transferring business assets (medical equipment, interior, patient information, etc.) and goodwill. On the other hand, for medical corporations, the primary schemes are typically “equity transfer” or “business transfer (merger),” depending on the corporate structure.
In medical corporations with equity interests, the transfer of equity held by the representative director results in the transfer of management rights and property rights of the corporation. In this case, the corporation itself continues to exist, and its licenses and employment contracts generally remain in effect. For M&A of medical corporations without equity interests, such as those with fund contributions, business transfer or merger schemes are often used, which can involve establishing a new medical corporation or merging into an existing one. These differences in schemes affect procedural complexity, the acquisition of necessary licenses, and the scope of responsibility after the transfer.
| Item | Individual Practice (Business Transfer) | Medical Corporation (With Equity) | Medical Corporation (Without Equity / Fund Contribution Type) |
|---|---|---|---|
| Subject | Business assets, goodwill, liabilities | Corporate equity interests | Corporate business (assets/liabilities) |
| Contract Type | Business Transfer Agreement | Equity Transfer Agreement | Business Transfer Agreement, Merger Agreement |
| Capital Gains Tax | Comprehensive taxation (up to 55%) | Separate taxation (approx. 20.315%) | Taxation on corporate asset sales, etc. |
| License Succession | Re-acquisition generally required | Continuation generally applies | Re-acquisition or modification procedures generally required |
| Liability Succession | Generally not inherited | Generally attributable to the corporation | Inherited based on the contract |
Significant Differences in Capital Gains Tax and Tax Savings
The tax burden in M&A is one of the most critical considerations for the seller. When an individual practitioner transfers their business, the profit from the transfer is subject to “comprehensive taxation,” meaning it is aggregated with other income as “business capital gains.” The top income tax rate is 45%, and with an additional 10% resident tax, the maximum applicable tax rate can reach 55%. In contrast, when equity interests in a medical corporation are transferred, the profit is subject to “separate taxation,” taxed independently of other income as “capital gains from the transfer of stocks, etc.” The tax rate is approximately 20.315%, comprising 15% income tax, 5% resident tax, and 0.315% reconstruction special income tax.
This difference in tax rates is substantial and critically affects the net proceeds from the sale. For example, with a ¥100 million capital gain, individual practitioners might face taxes of approximately ¥45 million to ¥55 million, whereas a medical corporation would incur taxes of about ¥20.315 million. Furthermore, individual business owners may be subject to business tax, and its treatment differs for medical corporations, which requires consideration. However, in business transfers, tax-saving measures may exist depending on the case, such as investment tax credits or special provisions for certain asset sales. Reducing capital gains tax is a major reason to consider incorporation.
Estimated Tax Rates on Capital Gains Comparison
Individual Practice (Business Transfer): Up to Approx. 55% (Comprehensive Taxation)
Medical Corporation (Equity Transfer): Approx. 20.315% (Separate Taxation)
※ Tax amounts vary by individual case. Consultation with an expert is essential.
Management Benefits and Drawbacks of Incorporating as a Medical Corporation
Incorporating as a medical corporation offers numerous benefits not only during M&A but also in daily operations. Key advantages include tax savings through income distribution (utilizing executive compensation and retirement benefits), improved employee welfare through social insurance coverage, enhanced external credibility, and easier expansion to multiple locations. Particularly, the stability of a corporation can be a strength in adapting to future changes in the business environment, such as trends in medical fee revisions and bed restructuring in regional healthcare plans. For medical corporations with equity interests, smooth business succession through changes in membership is also a significant attraction.
However, there are also disadvantages. Establishing a medical corporation requires approval from the prefectural governor, taking about six months to a year and incurring costs such as professional fees. After establishment, there are ongoing operational constraints and complexities not present in individual practices, such as regular reporting obligations to administrative bodies, limitations on executive compensation, and issues with the inheritance tax valuation of equity interests. For medical corporations with equity interests, high equity valuations can lead to substantial inheritance tax liabilities, making advance planning crucial.
Optimal Timing and Process for Incorporation with M&A in Mind
When considering incorporation with M&A in mind, timing is crucial. Generally, M&A conducted three to five years after incorporation is considered tax-advantageous and desirable for demonstrating stable corporate performance. This is because selling immediately after incorporation carries the risk of being treated as a sale of an individual business, thus forfeiting tax benefits. Working backward from the retirement date and allowing ample preparation time is key to success.
The process of incorporating as a medical corporation begins with an application for approval from the prefectural governor. This involves extensive document preparation, including drafting articles of incorporation, appointing members and directors, and creating an inventory of assets. After approval, corporate registration is completed, followed by various licensing procedures, such as submitting notifications to the public health center. As mentioned, these procedures typically take six months to a year. The M&A process itself often takes six months to a year from matching to closing, so planning must encompass both incorporation and M&A as a whole.

Equity Interests vs. Funds: Key Discussion Points in M&A
In the M&A of medical corporations, the corporate structure, particularly the presence or absence of “equity interests,” is a crucial point. In medical corporations with equity interests, management and property rights are transferred by selling the equity interests held by the members (shareholders). The valuation of these equity interests is often calculated based on the net assets of the corporation, and the valuation method and inheritance tax planning directly impact the success of the M&A and the net proceeds. When changing members, approval from the general meeting of members and the execution of an equity transfer agreement are necessary.
On the other hand, in “fund contribution type medical corporations” without equity interests, the transfer scheme is fundamentally a business transfer or merger, as there are no equity interests to transfer. Funds are contributions for the corporation’s operating capital, and while there is an obligation to repay them, repayment is limited to the extent permitted by the corporation’s financial status, and the tax treatment upon repayment is complex. In M&A of fund contribution type medical corporations, the assets and liabilities of the corporation are evaluated, and the business is transferred. The acquiring party will either establish a new medical corporation or merge the business into an existing one.
In either case, the medical institution’s medical fee performance, compliance with facility standards, acquisition of licenses, and its positioning within future regional healthcare plans significantly influence the M&A valuation and feasibility. It is essential to comprehensively assess these complex factors and select the appropriate scheme.
