The second move nobody plans for at the aliyah seminar
Israel taxes you on the way out. Ceasing Israeli tax residency triggers a deemed sale of your assets under section 100A of the Income Tax Ordinance, and the accrued gain becomes taxable even though nothing was sold7. Only a person who arrived can leave again, which is why this rule is an oleh rule.
Your neighbour who was born here and will die here never confronts section 100A. You might. A spouse gets a posting, a parent in Manchester or Toronto starts needing daily care, a company moves its engineering back to the head office, a marriage ends and one side goes home. None of that is failure and none of it is disloyalty. It is the ordinary arithmetic of a life with two countries in it. The useful question is not whether you will leave. It is whether the assets you are buying today will be easy or ruinous to carry across that border if you ever do.
General information, not advice
Israeli side: what actually triggers the charge, and how is the date fixed?
The trigger is the loss of Israeli tax residency, not a flight, a lease ending, or a change of address at the post office. Israeli residency turns on where your centre of life sits, so the relevant facts are your home, your family, your work, your habitual presence, and your economic ties, weighed together7. Section 100A then treats your assets as sold on the day before you stopped being a resident, and that day becomes the valuation date for everything you own7.
The practical consequence is that the date is a factual finding, and you are the one who has to evidence it years later. A date moved by twelve months moves the valuation, the apportionment and the size of the charge. Keep the tenancy termination, the school deregistration, the employment contract abroad and the closing statement of the Israeli account. This is the paperwork nobody keeps and everybody later needs.
There is a genuinely important oleh interaction here. New and returning residents hold a ten-year exemption on foreign-source income and on gains from assets held abroad8, and from 1 January 2026 the reporting reform makes affected years report-but-still-exempt rather than invisible9. So if you leave inside your exemption window, your foreign assets and your Israeli assets can be in completely different positions on the same day. That asymmetry is invisible to a native Israeli, because a native never had the exemption in the first place.
Israeli side: do you pay on the way out, or defer to the real sale?
You choose, and the choice is about timing and cash rather than about whether Israel gets paid. Paying at exit settles the deemed gain in the departure year and closes the file. Not paying is treated as an election to defer to the day you actually sell, at which point Israel takes its slice of the real gain7. The slice is apportioned by time: the share of your holding period that fell while you were an Israeli resident. Hold something for ten years, be resident for six of them, and roughly sixty percent of the gain is the Israeli portion.
Deferral is not free. It keeps an Israeli obligation attached to an asset you own in another country, which means Israeli filings and Israeli record-keeping for as long as you hold it. Buy a position at thirty and hold it to retirement, and deferral can mean a filing tail measured in decades on one line item. Test that consciously, because defaulting into it is exactly what happens when you simply do not pay.
| Asset | Does the deemed sale bite? | Pay-now cost | Defer-and-file consequence | Matching step-up abroad? |
|---|---|---|---|---|
| Israeli listed shares | Yes, a straightforward capital asset with a public valuation | Cash in the departure year on a gain you have not banked | Israeli filing tail until you sell; Israel takes the time-based slice | Not in the US: basis stays cost, and a foreign deemed sale is not on the list of adjustments4 |
| Foreign brokerage account | Depends on your exemption window: foreign assets sit under the oleh ten-year relief8 | Often nothing while the window is open, which is the argument for leaving inside it | The question becomes what happens after year ten, so the date of the move drives the answer | Irrelevant where Israel never taxed the gain; relevant the moment it did |
| Israeli apartment (מס שבח (Mas Shevach)) | Israel does not need a deemed sale to keep this one | Nothing on departure; the charge arrives on the real sale | You stay in the Israeli system for this asset whatever else you do | The treaty leaves gains on real property to the state where it sits1 |
| קופת גמל (Kupat Gemel) and קרן השתלמות (Keren Hishtalmut) | Taxed on withdrawal under their own regime, not as an ordinary deemed sale | No exit cash call, which is why people forget these exist | Withdrawing from abroad is where it gets complicated, not the departure itself | A lump sum may fall outside the treaty pension article, which covers periodic payments1 |
| Private company shares | Yes, and this is where the charge is largest and least liquid | Cash on a valuation nobody can convert to money; the valuation itself is contestable | A long tail, often a decade or more, on the asset you can least afford to fight about | Not in the US, and the illiquidity means you may pay twice on paper before any cash exists4 |
Home-country side: does your destination give you a matching basis step-up?
If your destination is the United States, no. US basis is generally your cost, adjusted only for a defined list of events, and a foreign country's deemed disposition is not one of them4. So Israel taxes a gain measured to your departure date, your US basis carries on from what you originally paid, and when you actually sell, the US measures the entire gain from the original purchase. The same growth appears in two tax bases.
The second half of the problem is worse than the first, and almost nobody sees it coming. Gain on the sale of personal property, including stock, is US-source income when the seller is a US resident3. The foreign tax credit is limited to US tax on foreign-source income within the same category, so a US-source gain generates no credit capacity whatsoever3. Unused foreign taxes carry back one year and forward ten3, which sounds like a rescue and usually is not, because the carried credit still needs foreign-source income in the same basket to land on. Move back to the US, sell there, and there may be nothing at all for the Israeli tax to offset.
Treaty side: what the US-Israel convention does and does not fix
The treaty allocates taxing rights; it does not synchronise calendars. Under Article 15, a resident of one state is exempt from tax by the other on gains from disposing of capital assets, with listed exceptions including real property and certain substantial holdings in an Israeli corporation1. Article 7 leaves income and gains from real property to the state where the property sits, and gains on shares of a real estate association as defined in the Israeli Land Appreciation Tax Law may be taxed by Israel1.
Two clauses do the damage for an American. Article 6(3) lets a contracting state tax its residents and its citizens as if the convention had not come into effect, which is why US citizenship follows you regardless of where you live; Article 6(4) preserves a short list of articles from that override, including Article 26 on relief from double taxation1. And Article 26 grants the US credit "in accordance with the provisions and subject to the limitations of the law of the United States", stating that the credit shall not exceed the limitations provided by US law for the taxable year1. The treaty hands you back to the domestic rules that created the mismatch. It is a real protection against being taxed twice on the same income in the same year by two countries. It is not a protection against being taxed twice on the same growth in two different years.
One more verified detail worth carrying: Article 20 makes private pensions and similar remuneration taxable only in the state of residence, and defines the term as periodic payments1. A single lump-sum withdrawal from an Israeli long-term savings product is not obviously a periodic payment, so do not assume the pension article covers it.
One portfolio, run both ways
Dana made aliyah in 2021 and is weighing a 2029 return to Boston. She holds Israeli listed shares bought in 2023 for ₪400,000, worth ₪1,000,000 on the departure date: a gain of ₪600,000, about $162,000 at an illustrative ₪3.70 to the dollar (the Bank of Israel publishes the representative rate you would actually use10). Her holding period is entirely inside her Israeli residency, so the time apportionment gives Israel the whole ₪600,000 as its base.
Pay now. She settles the Israeli charge on ₪600,000 in 2029 and closes the file. She needs the cash in a year she is also paying for an international move, and she has sold nothing. When she sells in 2033 for ₪1,300,000, the US measures her gain from the 2023 cost, not from the 2029 value4, so roughly $243,000 of gain lands on her US return at long-term rates, currently 0, 15 or 20 percent depending on her taxable income (2025 tax year)°5. At 15 percent that is about $36,000 of US tax. The Israeli tax she paid in 2029 sits in a closed year, and the 2033 gain is US-source, so there is no limitation capacity for it to reduce3.
Defer. She pays nothing in 2029. In 2033 Israel takes its time-apportioned slice of the real gain and the US taxes the same sale in the same year, which is at least the right shape for a credit. It still does not fix the source problem: a US resident selling stock produces US-source gain3, and the credit needs foreign-source income to work against. What deferral genuinely buys her is four years of not paying tax on money she has not received, and the option to never pay it if the position falls. What it costs her is an Israeli filing obligation carried to Massachusetts.
US persons: a deemed sale that is not a sale, on funds that are already PFICs
If you are a US citizen or green-card holder holding Israeli pooled funds, the Israeli deemed sale is an Israeli event only. It is not a US disposition, so it does not close your PFIC holding period and it does not reset anything on the US side. Your holding period keeps running underneath the Israeli charge, and under the default section 1291 treatment the gain on the eventual real disposition is allocated rateably across that entire holding period with an interest charge attached6.
Two practical consequences follow. First, you can end up paying real Israeli tax on a notional Israeli sale while the US position is unchanged, and then meeting the punitive section 1291 arithmetic later anyway on the full period. Second, the annual Form 8621 obligation does not stop because you left Israel. The section 1298(f) annual reporting duty applies to shareholders, subject to a de minimis exception where aggregate PFIC stock value does not exceed $25,000, or $50,000 on a joint return, at year end and there were no excess distributions or dispositions6. Holding a single Israeli fund across a move can therefore mean Israeli exit exposure, continued US filings, and no cash from anything.
This is the clearest argument for the rule US-citizen olim keep meeting: in a taxable account, non-US pooled funds are the expensive shape, while a US-domiciled fund sidesteps the PFIC regime entirely. QEF and mark-to-market elections change the picture materially and both need professional help before, not after, the purchase.
What newcomers get this wrong on
- Treating the exit tax as a leaving problem. It is a buying problem. The asset you choose in your second year determines the size and messiness of a charge you may meet in your twelfth.
- Assuming the treaty prevents double taxation here. It prevents two countries taxing the same income in the same year. It does not fix two countries taxing the same growth in different years1.
- Assuming a destination gives you a matching basis. The US does not4. Ask the question of your specific destination before you move, because the answer changes the whole calculation.
- Defaulting into deferral by simply not paying. That is an election with a long compliance tail, and it deserves a decision rather than an omission.
- Forgetting the illiquid assets. Private company shares, vested options and closely held interests are where the largest deemed gains hide, and they are exactly what you cannot sell to pay the charge.
- Confusing this with the US expatriation charge. Giving up US citizenship or a long-held green card is a separate regime with its own tests. These are different rules that share a nickname.
The decision procedure, in the order that works
- List every asset, including the ones that are not in a brokerage statement. Israeli and foreign securities, the apartment, long-term savings products, private company shares, vested options, business interests.
- Mark the unrealised gain on each, and the acquisition date. The date matters as much as the number, because the apportionment is a time fraction.
- Split the list by exemption status. Foreign assets inside your ten-year oleh window behave differently from Israeli assets on the same day8, and from 1 January 2026 affected years are reportable even where they remain exempt9.
- Ask your destination the basis question in writing. Does it recognise the Israeli deemed sale as your cost base? For the US the answer is no4.
- Test deferral against your real holding horizon. If deferring leaves you filing Israeli returns for ten or twenty years on one line item, price that compliance rather than ignoring it.
- Take the list, not the question, to a cross-border professional. An adviser who is handed an itemised schedule with dates and valuations gives you a usable answer. One who is handed "we might move" cannot.
Knowledge Check
A US-citizen oleh pays the Israeli deemed-sale charge on departure in 2029, moves back to the US, and sells the same shares in 2033. Why might none of that Israeli tax reduce the US bill?
If you want to see the shape of the number before you talk to anyone, the Israel Exit-Tax Estimator runs the pay-now and apportioned-deferral routes on your own figures, and the guide to the oleh ten-year exemption covers the window that decides how much of this ever applies to your foreign assets.
Ceasing Israeli tax residency triggers a deemed sale of your assets under section 100A of the Income Tax Ordinance: Israel treats everything you own as sold the day before you stop being a resident and taxes the accrued gain, even though nothing was sold and no cash arrived. This is an oleh rule in practice, because only someone who arrived can leave again. You either pay the charge on the way out or you are treated as deferring it to the day you really sell, at which point Israel takes the share of the gain that accrued during your Israeli-residence years. For US citizens the deferral does not solve the deeper problem: the US gives no basis step-up to match the Israeli deemed sale, and a gain realised while you are a US resident is US-source income, which generates no foreign tax credit capacity at all.
Losing Israeli tax residency, which turns on where your centre of life sits rather than on any single act of leaving. Section 100A then treats your assets as sold on the day before you ceased to be a resident, and that date fixes the valuation for everything you own. Because it is a factual finding, keep the evidence: lease termination, employment contract abroad, school deregistration, account closures.
Paying on exit closes the file but demands cash in your most expensive year on a gain you have not banked. Deferring is the default if you simply do not pay, and Israel then takes the time-apportioned share of the real gain when you sell. Deferral keeps an Israeli filing obligation attached to the asset, potentially for decades, so treat it as a decision rather than an omission.
By time apportionment. Israel takes the share of the gain matching the share of your total holding period during which you were an Israeli resident. Hold an asset for ten years and be resident for six of them, and roughly sixty percent of the gain is the Israeli portion. Growth from before your aliyah is carved out, which is the main relief in the mechanism.
New and returning residents hold a ten-year exemption on foreign-source income and on gains from assets held abroad, so foreign assets and Israeli assets can be in different positions on the same departure date. From 1 January 2026 the reporting reform makes affected years reportable even where they stay exempt from tax. Whether the window is open on your departure date matters enormously, so check it against your actual aliyah date.
No. US basis is generally your cost, adjusted only for a defined list of events, and a foreign deemed disposition is not among them. So Israel taxes the gain to your departure date, your US basis stays at what you originally paid, and the US measures the entire gain from the original purchase when you actually sell. The same growth sits in two tax bases.
Often not, for two compounding reasons. The credit is annual and by category, and unused foreign taxes carry back one year and forward ten, so a 2029 Israeli tax may be stranded against a 2033 sale. Worse, gain on selling stock is US-source income when you are a US resident, and the credit is limited to US tax on foreign-source income, leaving nothing for it to offset.
Nothing helpful. The Israeli deemed sale is not a US disposition, so your PFIC holding period keeps running and the default section 1291 treatment still allocates the eventual gain rateably across the whole period with an interest charge. The annual Form 8621 duty continues too, subject to the de minimis exception where aggregate PFIC value stays at or below $25,000, or $50,000 jointly, at year end.
No, and confusing them is common. The Israeli charge applies when you stop being an Israeli tax resident, whatever passport you hold. The US expatriation regime applies when a citizen renounces or a long-term green-card holder gives up that status, and has its own tests and thresholds. They are separate rules that share a nickname, and you can meet one, both, or neither.
