Quick Answer: A Delaware flip puts a new U.S. parent company on top of an Israeli startup. Every shareholder swaps Israeli shares for shares in the parent, and the Israeli company carries on as a wholly owned subsidiary. For Israeli-resident shareholders the swap counts as a sale, so it is taxable unless the Israel Tax Authority approves it under Section 104B(a) of the Income Tax Ordinance, usually on its "green track" Form 982. Deferral comes with two years of restrictions: the IP and activity stay in the Israeli company, the pre-flip holders keep at least 25% of the parent, and the shares sit with an Israeli trustee.

American venture funds like to invest in a Delaware C-corporation. They know the corporate law, their financing documents are written for it, and some funds are barred by their own partnership agreements from holding a foreign operating company directly. So when a U.S. lead investor appears, an Israeli startup is often asked to "flip": to slide a Delaware company in above the Israeli one before the round closes.

Founders tend to treat this as paperwork. Israeli tax law does not. The share swap is a disposal of the Israeli shares at market value, and the deferral that makes it painless is a conditional ruling with its own deadlines. This guide covers what the Tax Authority's form actually requires, what you are bound to afterwards, and where a foreign investor or a founder living abroad fits in.

1. What a Delaware Flip Is

A new company is incorporated abroad, almost always in Delaware. The shareholders of the Israeli company transfer all their shares to it and receive shares of the new company in the same proportions. Nothing else moves. The Israeli company keeps its registration, its employees, its contracts and its technology, and now has a single shareholder. Israeli practitioners also call this an inversion, and the Tax Authority's own form describes it as a transfer of all the rights in an Israeli-resident company to a foreign-resident company.

The motive is commercial. Besides investor comfort, U.S. holders often want stock in a domestic C-corporation because some U.S. tax reliefs for startup shares, such as the qualified small business stock rules, are only available for stock of a U.S. corporation. A U.S. listing or a sale to an American buyer is also simpler from a Delaware parent.

2. How the Share Swap Works

  • Form the parent. A new Delaware corporation is set up with no assets and no liabilities, and with a share structure that mirrors the Israeli cap table.
  • Get the tax ruling. The application to the Israel Tax Authority is filed before the swap, not after (see section 4).
  • Exchange the shares. Every holder contributes Israeli shares and receives parent shares of the same class and proportion. No cash changes hands.
  • Replace options and convertibles. Employee options, warrants and SAFEs are swapped for equivalent rights in the parent.
  • Deposit with the trustee and update the registers. The exchanged shares go to an Israeli trustee, and the Israeli company reports its new sole shareholder to the Companies Registrar (Rasham HaChavarot).

A flip does not move the company to America. The Israeli subsidiary stays an Israeli tax resident, and the green-track ruling says so in terms. After the flip you run two companies, each with its own filings.

3. Why the Swap Is Taxable in Israel, and Who Pays

Exchanging shares of one company for shares of another is a sale under Part E of the Income Tax Ordinance. An Israeli-resident individual pays 25% on the real gain, or 30% if they are a substantial shareholder (10% or more of the company). On top of that comes the surtax on high incomes: in 2026, 3% on taxable income above NIS 721,560, plus a further 2% on capital-source income above the same threshold. A founder whose shares cost almost nothing and are now valued at a Series A price would owe tax on paper wealth, with no cash from the deal to pay it.

Section 104B(a) of the Ordinance, in the restructuring chapter (Part E2), lets shareholders transfer all their rights in a company to another company in return for shares only, without tax at the time of transfer. The gain is not forgiven. It is rolled into the new shares and taxed when they are eventually sold. Because the receiving company here is foreign, the transfer needs the Tax Authority's advance approval.

Non-Israeli shareholders are in a different position. A foreign resident is generally exempt from Israeli capital gains tax on shares of an Israeli company that is not mainly a real-estate holding vehicle, so for them the swap usually triggers no Israeli tax in the first place. The deferral machinery exists for the Israeli founders, angels and employees.

4. The Green Track: Form 982 and Its Entry Conditions

In 2018 the Tax Authority published a "green track" (maslul yarok) for flips. It is a standard-form ruling request, Form 982, in which the applicants declare a list of facts and accept a fixed set of conditions. If the facts fit, the professional division issues the ruling on those terms without negotiating each clause. It is not automatic approval, and a company that cannot make every declaration has to apply for an individually negotiated pre-ruling instead.

The main declarations in the form are these:

  • The Israeli company was incorporated after January 1, 2018, and its auditor's reports carry no qualification.
  • The parent is a new company formed for the flip, resident in a country that has a tax treaty with Israel, and not a tax-transparent entity there. A Delaware LLC taxed as a partnership would not fit; a C-corporation does.
  • The parent's country has a statutory corporate tax rate above 15%, taxes passive profits of controlled foreign companies, and its treaty with Israel sets withholding of at least 10% on dividends from the Israeli company to the parent.
  • The holders transfer all their rights and receive shares only. No cash or other consideration is paid to them or to related parties, directly or indirectly.
  • The Israeli company is not a real-estate association, and no asset, activity or intangible leaves Israel as part of the transaction.
  • The application is filed during the three months before the flip date.
In Practice: The incorporation-date test catches more companies than founders expect. A startup founded in 2017 is outside the form however small it is, and goes down the slower individual ruling route. Check this, and the "shares only" declaration, when the term sheet arrives. A side payment to a departing co-founder as part of the same deal can be enough to void the ruling retroactively.

5. What You Sign Up To for Two Years

The ruling defers the tax on condition that the structure stays put for the "required period" in Part E2, which is two years. The form spells out what that means:

  • Activity and IP stay in the Israeli company. All the activity and assets it owned before the flip, including intangibles and rights derived from them, remain with it throughout the period.
  • The 25% floor. The people who held rights immediately after the flip must together keep at least 25% of each class of rights in the parent, measured on a fully diluted basis. Sales and dilution both count.
  • The parent keeps the subsidiary. The parent must hold all of the transferred Israeli shares for the whole period.
  • Trustee. Within 15 days of the flip, the parent shares of every "liable" holder, and the Israeli shares now held by the parent, are deposited with an Israeli trustee. The trustee withholds tax when shares are sold and reports each sale to the assessing officer within 30 days.
  • Dividends. A dividend from the Israeli company to the parent out of profits generated up to the end of the second year after the tax year of the flip is taxed at Israeli domestic rates, with no treaty reduction. Treaty rates apply only to later profits.
  • Sale of the subsidiary. If the parent sells the Israeli shares, the part attributable to the liable holders is taxed in Israel as if an Israeli company had sold them.

If Section 104B or the ruling is breached, the exchange becomes taxable under Section 104G, and the company and the liable holders must hand the assessing officer an expert valuation of the company as of the flip date within 30 days. One more cost is easy to miss: the ruling bars any deduction for the legal, audit and advisory fees of the restructuring itself.

Illustrative Scenario: A company flips in March and closes its Series A in May. Fourteen months later an acquirer offers to buy the whole parent for cash. A sale of 100% takes the pre-flip holders below the 25% floor inside the two years, so the deal cannot simply sign. Counsel has to go back to the Tax Authority's restructuring department before closing and settle how the original exchange and the sale will be taxed. The same check applies, less dramatically, to a large secondary sale by founders or an unusually dilutive round.

6. Employee Options Under Section 102

Israeli employees usually hold options in the capital gains track of Section 102 of the Ordinance: the options are held by a trustee, and if the statutory holding period is met the employee pays 25% on sale instead of marginal income tax of up to 47%. A flip replaces those options with options over parent stock, which could be read as a disposal.

The green-track ruling deals with this directly. The replacement is not a tax event for the employees or the companies, provided that:

  • the new options carry the same terms and economic value, with no added benefit through the exchange ratio or exercise price;
  • the Section 102 trustee continues to hold them, under the Israeli plan as adopted by the parent or under a parent plan filed with the assessing officer;
  • the holding period is counted from the original grant date, so the clock does not restart.

One trap sits in the form. Options granted in the capital gains track during the 90 days before the flip agreement is signed fall under Section 102(b)(3), which treats part of the gain as employment income. Avoid a round of grants just before signing. Options held by consultants and controlling shareholders under Section 3(i) get similar continuity and are deposited with the flip trustee.

7. Israel Innovation Authority Grants

A company that has received grants from the Israel Innovation Authority carries obligations under the Encouragement of Research, Development and Technological Innovation in Industry Law 5744-1984. The funded know-how may not be transferred outside Israel without the Authority's approval, and an approved transfer comes with a payment that can reach six times the grants received, plus interest.

A properly built flip does not transfer know-how. The IP stays in the Israeli subsidiary, which is also what the tax ruling demands. What the flip does change is control: the company must report the change to the Authority, and the new foreign parent, as an interested party, signs an undertaking to comply with the R&D Law. The exposure comes later, if someone decides to consolidate the IP in the U.S. parent. At that point both the Innovation Authority payment and Israeli tax on a sale of IP come into play. The tax ruling says expressly that it does not release anyone from reporting a sale of the intangibles, including ones created after the flip.

The form also asks whether every regulatory approval needed for the restructuring has been obtained, so the Innovation Authority filing belongs in the same workplan as the tax application. For the grant rules themselves, see our guide to Israel Innovation Authority grants.

8. If You Are a Foreign Investor or a Founder Living Abroad

The ruling sorts shareholders into "liable" and exempt. Liable holders are Israeli residents, foreign residents who are not entitled to an exemption on a sale of the parent's shares, and anyone whose residency the Tax Authority is disputing. Their shares go to the trustee.

  • Foreign funds and angels. Expect to be asked for a signed declaration of foreign residency and exempt status for the application. Give it on time; a holder who has not declared is treated as liable and swept into the trust arrangement. The assessing officer keeps the right to challenge the declaration later.
  • Founders who relocate. Moving to the U.S. after the flip does not end the Israeli claim. Under the ruling, anyone who was an Israeli resident on the eve of the flip is treated as one until the deferred tax is paid in full.
  • Relocating employees. The benefit on the replaced options is treated as Israeli-source income, and the employee as an Israeli resident for that income until exercise, with a foreign tax credit considered only if foreign tax was actually paid.
  • U.S. citizens among the holders. The exchange also has to work under U.S. tax law, and the parent may become subject to U.S. rules on controlled foreign corporations once it owns the Israeli company. That is a question for U.S. counsel, and it should be asked before the Israeli application is filed.

9. Deadlines, and Running Two Companies

The dates that matter all come from the ruling:

  • Three months before: the window in which the application must be filed.
  • 90 days after the ruling is signed: the transfer must be completed, or the ruling is void retroactively unless an extension was given in writing.
  • 15 days after the flip: shares deposited with the trustee.
  • Two years: the required period for the IP, 25% and holding conditions.

Any material change in the facts between the ruling and the flip, including a change in who the shareholders are, has to be taken back to the restructuring department. A new investor joining the cap table in that gap is such a change.

Afterwards the Israeli subsidiary files its own annual report and tax returns, and the first financial statements after the ruling must include a note setting out its terms. Because parent and subsidiary now deal across a border, Section 85A of the Ordinance applies: the Israeli company has to be paid an arm's-length price for the R&D it performs for the group, backed by transfer pricing documentation. The ruling warns that payments from the subsidiary to the parent outside the ordinary course of business at market price are treated as dividends. Our guide to annual compliance for an Israeli company covers the routine filings.

10. When a Flip Is the Wrong Move

With no U.S. investor and no U.S. exit in view, a Delaware parent adds a second set of filings and little else. The two-tier structure also costs money at exit if the buyer wants the technology and not the shares: a sale of IP by the Israeli subsidiary is taxed there at the 23% corporate rate, and the proceeds are taxed again as a dividend on the way up to the parent.

Timing matters too. A flip done before there is much value carries little tax exposure if a condition is later broken. A flip done at a high valuation defers a large liability and leaves the founders managing the 25% floor through the next two years of fundraising. Founders who already expect American money often incorporate the Delaware parent on day one with the Israeli company beneath it, which avoids the restructuring and the ruling altogether. I think that is the better default for a team that has not yet issued shares to anyone.
