The Flip-Up Structure for Startups Expanding Abroad: What, Why, and How?

Short answer: A "flip-up" (sometimes called a "flip" or "inversion") is a transaction in which the shareholders of a Turkish company transfer their shares — not for cash, but through a share-for-share exchange — to a newly incorporated foreign holding company (typically a Delaware C-Corp or a Cayman/BVI entity), so that the Turkish company becomes a 100% subsidiary of that foreign holding company. As a result, foreign investors invest in the foreign holding company rather than directly in the Turkish company, while the Turkish founders receive shares in the holding company in exchange for their shares in the Turkish company. While this structure moves the company into a legal framework familiar to foreign investors, it requires careful planning around issues such as whether the share transfer is treated as a taxable "disposal" in Turkey, foreign exchange notifications, and the Controlled Foreign Company (CFC) regime.

Why do a flip-up?

For startups expanding abroad or aiming to raise larger-scale (Series A and beyond) foreign investment, the main motivations for a flip-up are:

• Investor demand: Most US-based venture capital funds, for reasons related to their fund management agreements and tax structures, do not want to invest directly in a foreign (Turkish) company; they require the investment to be made into a Delaware C-Corp.
• Standardized investment documentation: Documents such as SAFEs, share purchase agreements, and option plans are generally standardized under US/Delaware law; adapting these documents to Turkish law adds extra negotiation and cost.
• Exit strategy: If the company is likely to be acquired by a foreign technology company (M&A), the acquirer generally prefers to carry out due diligence and the transfer process under its own legal system.
• IP consolidation: Consolidating trademarks, software, and patents under a single international legal entity facilitates licensing and international commercial agreements.

The mechanism: how does the share exchange work?

At the heart of a flip-up transaction is a "share exchange agreement." Under this agreement:

1. A holding company is incorporated abroad (typically an "empty shell" company in which the existing founders of the Turkish company hold shares in the same proportions).
2. The shareholders of the Turkish company transfer their shares in the Turkish company to the holding company — without receiving any cash — in exchange for shares the holding company issues to them.
3. The exchange ratio is generally 1:1 — that is, an X% stake in the Turkish company becomes the same X% stake in the holding company — although different ratios may be used for tax or structural reasons.
4. At the end of the process, the Turkish company becomes a 100% subsidiary of the holding company; the Turkish company's share ledger and trade registry records are updated accordingly.

Legal and financial consequences on the Turkish side

1. Share transfer and capital gains tax

Even though no cash changes hands, the transfer of Turkish founders' shares in the Turkish company to the foreign holding company may be treated, under the Income Tax Law and the Corporate Tax Law, as a "disposal" of those shares. In that case, the difference between the fair value of the transferred shares at the time of the transaction and their cost basis may be subject to tax as a capital gain (for individual shareholders) or as corporate income (for corporate shareholders) — even though the transaction generates no cash proceeds. This "paper gain, no cash" (dry income) problem is the most critical tax issue in flip-up planning. In some cases, carrying out the flip-up at an early stage — when the fair value of the shares is still low (close to incorporation) — can significantly reduce this tax risk.

2. Foreign exchange legislation: notification of indirect outward investment

The transfer of shares in the Turkish company to a foreign holding company, in exchange for shares in that holding company, may be treated as an "outward direct investment" transaction under Law No. 1567 and Decree No. 32, giving rise to a notification obligation to the Ministry of Treasury and Finance. In addition, because the Turkish company becomes a company with direct foreign capital as a result of the transaction, the Ministry of Trade's foreign capital notifications must also be updated.

3. The Controlled Foreign Company (CFC) regime

After the flip-up, the Turkish founders no longer hold shares in the Turkish company directly, but in the foreign holding company. If the founders hold these shares through a fully liable corporation in Turkey, the holding company's income (particularly if it is passive in nature) may be taxable in Turkey under the CFC regime in Article 7 of the Corporate Tax Law. The CFC regime does not apply directly to individual founders, but any dividends distributed to them will be subject to income tax in Turkey.

4. "Migrating" existing investors and employee options

If the Turkish company already has investors (angel investors, VCs) or employee options/profit-sharing certificates issued prior to the flip-up, all of these must be included in the share exchange and re-established with equivalent rights within the new holding company. This requires both running consent/approval processes with existing investors and adapting the option plan to the new legal system (typically a US state law).

5. KVKK and data transfers

After a flip-up, the foreign holding company may gain access to personal data (customer and employee data) processed by the Turkish company. In that case, the provisions of the Turkish data protection law (KVKK) on transferring personal data abroad (Article 9, and the transfer mechanisms set by the Personal Data Protection Board — an adequacy decision, an undertaking, or Board approval) come into play; the post-flip-up intra-group data flow must be legitimized through one of these mechanisms.

A practical checklist

• Timing the flip-up: carrying it out while the company's value is still low (ideally close to incorporation) can reduce the tax burden in Turkey.
• Ensuring the share exchange agreement is valid and enforceable both under Turkish law and under the law of the jurisdiction where the holding company is incorporated.
• Obtaining the required consents from all existing investors and option holders (typically under the drag-along or consent provisions of the shareholders' agreement).
• Making the required foreign exchange and foreign capital notifications within the deadlines that run from the transaction date.
• Preparing a KVKK-compliant intra-group data transfer agreement before the transaction.
• Modeling, together with a tax advisor, the cash-flow impact of any capital gains tax that the flip-up may trigger in Turkey.

Conclusion

A flip-up can be a strategically sound step for a Turkish startup aiming to raise foreign investment or scale internationally — but the technical simplicity of the transaction (signing a share exchange agreement) conceals the complexity of its tax and foreign exchange consequences on the Turkish side. In particular, the risk of "no cash received but potentially taxable gain" can turn into a significant financial burden for founders if the flip-up is not carried out at the right time and with the right structure. For this reason, before implementing a flip-up decision, obtaining joint support from an attorney and a tax advisor familiar with both Turkish law and the law of the target jurisdiction is critical to ensuring the process goes smoothly.
