Legal notice
This is a free information tool operated by an artificial intelligence model. It applies published rates and thresholds to figures you supply and produces a projection. It does all of this without the involvement, review, or approval of a licensed tax adviser, accountant, or attorney.
It is not tax advice, it is not a filed return, and it is not a professional opinion. What it produces is a preliminary worksheet for your own planning. It does not examine your books, does not verify your residency or business classification, does not model your Israeli tax position, does not decide whether any structure suits you, and does not recommend incorporating or not incorporating.
An AI model can err, omit data, or present a wrong conclusion. Any text it produces is an automatic draft for personal organisation only and must never be submitted to any authority as it stands.
Responsibility for reporting and for paying tax is yours, the binding assessment is made by the tax authority concerned, whether the Israeli Tax Authority or the IRS, and representation before a tax authority is reserved to those permitted to do so by law. This tool is not a substitute for advice that takes into account the particular data and needs of each person.

Problem
An American freelancing in Israel pays Bituach Leumi like everyone else, and then discovers a second social tax bill from a country they may not have lived in for years. The United States has social security agreements with thirty countries that stop exactly this double charge, and Israel is not one of them. Worse, the relief most Americans abroad rely on, the foreign earned income exclusion, does not touch self-employment tax at all. So a freelancer can owe zero US income tax and still owe thousands of dollars of US self-employment tax, usually finding out when a penalty notice arrives.
Instructions
Stage 1: Confirm the trap actually applies
Three conditions have to hold together. Check each rather than assuming:
- The user is a US person, a citizen or lawful permanent resident.
- The income is self-employment income, not salary. An osek patur or osek murshe invoicing clients is self-employed. A sachir on a tlush is not, and the analysis is different.
- Net earnings from self-employment are USD 400 or more, which is the threshold at which the
tax applies. On the form itself the test runs AFTER the 92.35 percent factor: Schedule SE
line 4c says "If less than $400, stop; you don't owe self-employment tax". Crossing USD 400
also creates a US filing obligation on its own, even when every dollar of income tax is
excluded, which is why many users are behind on returns, not just on payments. Filing
mechanics belong to
us-israel-dual-tax-navigator.
Then state the two facts that make this different from every other country's expats:
There is no US-Israel totalization agreement. The United States has social security agreements with Australia, Austria, Belgium, Brazil, Canada, Chile, the Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Japan, Luxembourg, the Netherlands, Norway, Poland, Portugal, the Slovak Republic, Slovenia, South Korea, Spain, Sweden, Switzerland, the United Kingdom, and Uruguay. Israel is absent from that list. Under such an agreement a person generally pays social taxes to only the country where they live. Without one, both systems charge.
The exclusion does not help. Foreign earnings from self-employment cannot be reduced by the foreign earned income exclusion when computing SE tax, and a self-employed US citizen living outside the United States must in most cases pay SE tax. This is the point users find hardest to believe, so state it plainly and cite it.
The result: Bituach Leumi and Israeli income tax on one side, US self-employment tax on the other, with the exclusion or the credit reaching only the US INCOME tax and never the SE tax.
The income tax treaty does not help either. Users ask this next. The US-Israel convention covers, for the United States, "the Federal income taxes imposed by the Internal Revenue Code", and its saving clause lets the United States tax its citizens as if the convention had not come into effect. It is not a social security agreement.
Stage 2: Project the SE tax
The computation, in the order Schedule SE performs it:
| Step | Operation | Authority |
|---|---|---|
| 1 | Start from net earnings from self-employment (business income less business expenses) | Schedule C feeds Schedule SE |
| 2 | Multiply by 92.35 percent (0.9235) | Schedule SE line 4a |
| 3 | Apply 12.4 percent for social security, up to the year's wage base | Rate is 12.4 percent of the 15.3 percent total |
| 4 | Apply 2.9 percent for Medicare, with no cap | Remainder of the 15.3 percent |
| 5 | Separately, Additional Medicare Tax of 0.9 percent above the filing-status threshold | Form 8959, NOT Schedule SE. See the threshold table below |
The combined rate is 15.3 percent, being 12.4 percent for social security and 2.9 percent for Medicare. Note that the 15.3 percent applies to the reduced base from step 2, not to the full net earnings, which is why a rough estimate using 15.3 percent of net earnings slightly overstates the bill.
The social security wage base is annual and it changes. For 2025 the maximum amount of self-employment income subject to social security tax is USD 176,100. For 2026 the maximum amount of earned income (wages and net earnings from self-employment) subject to social security tax is USD 184,500, published in the 2026 Form 1040-ES before that year's Schedule SE instructions exist. Use the figure for the year you are computing, never a prior year's. The Medicare portion has no cap, so income above the base is still charged at 2.9 percent.
The base is shared with wages. If the user also has social security wages on a US Form W-2, Schedule SE subtracts them from the base (lines 8a and 9) and applies 12.4 percent only to the smaller of the SE amount or what remains. Skipping this overstates the bill for anyone with US wages.
Additional Medicare Tax thresholds:
| Filing status | Threshold |
|---|---|
| Married filing jointly | USD 250,000 |
| Married filing separately | USD 125,000 |
| Single, head of household, or qualifying surviving spouse | USD 200,000 |
This 0.9 percent is computed on Form 8959, not on Schedule SE, so report it as its own line next to the SE tax rather than inside it. Where the user has Medicare wages as well, the threshold applying to the self-employment income is reduced by those wages. On a joint return the threshold is tested against both spouses' Medicare wages and self-employment income combined, so ask for the spouse's figures before saying the tax is not triggered.
Wages above the threshold are taxed too, on Form 8959 Part I, separately from the self-employment part. An employer withholds only on wages above USD 200,000 that it pays, regardless of filing status, so a married user filing separately with wages above USD 125,000, or a couple whose combined wages pass USD 250,000, can owe it with nothing withheld. Use box 5 Medicare wages for this, not the box 3 and 7 social security wages used for the wage base; the two figures can differ.
One relief that does exist. The employer-equivalent portion of SE tax is deductible in figuring adjusted gross income: Schedule SE line 13 takes 50 percent of line 12, the SE tax, and the Additional Medicare Tax is not part of it. Be precise about what that does: it reduces INCOME tax only. It does not reduce net earnings from self-employment and it does not reduce the SE tax itself. Users routinely hear "it is deductible" and assume the bill shrinks. It does not.
Stage 3: Set up the payment cycle
US tax on self-employment income is not withheld by anyone, so it is paid in quarterly estimated instalments during the year rather than in one lump at filing. SE tax counts toward the estimated-tax test, so a user whose US income tax is fully excluded can still be under-paid purely because of SE tax.
2026 schedule, from Form 1040-ES:
| Payment | Due |
|---|---|
| 1st | April 15, 2026 |
| 2nd | June 15, 2026 |
| 3rd | Sept. 15, 2026 |
| 4th | Jan. 15, 2027 |
The periods are not equal quarters, so say which instalment is next from today's date. The fourth is not required if the 2026 return is filed by February 1, 2027 with the whole balance paid.
Who must pay and how much avoids a penalty. Estimated tax is generally required where the user expects to owe at least USD 1,000 for the year. Paying the smaller of 90 percent of the current year's tax or 100 percent of the prior year's tax (for 2026, the 2025 return, which must cover all 12 months) avoids the penalty. If the prior year's adjusted gross income was more than USD 150,000 (USD 75,000 married filing separately), the 100 percent becomes 110 percent. Explain these tests and let the preparer apply them; they depend on the whole return, not the SE figure alone.
Catching up later does not erase earlier penalties. Per Form 1040-ES, the penalty is imposed on each underpayment for the number of days it remains unpaid. A user who skipped the first three instalments and pays it all in January still owes the penalty on each missed one.
Extensions do not stop interest. Per Publication 54, a US citizen or resident alien who qualifies (living outside the United States and Puerto Rico on the regular due date, see the publication for the full test) gets an automatic 2-month extension to file and pay federal income tax, but still pays interest on any tax not paid by the regular due date. The additional 4 months of time to file beyond that is not an extension of time to pay at all. None of this moves the quarterly instalment dates above.
Practical framing that helps more than a lecture: convert the projected annual SE tax into a percentage of each invoice the user should set aside as they get paid, in shekels, so the money exists when the instalment is due. Show the arithmetic rather than asserting a percentage.
Stage 4: Lay out the structural options without recommending one
Users invariably ask "how do I make this stop". There are recognised structural responses and each has real costs. Present them as a comparison for a professional conversation, and state clearly that choosing among them is not something this skill does.
| Option | The idea | What it costs or risks |
|---|---|---|
| Stay an osek and pay both | No restructuring | The full double charge every year |
| Operate through an Israeli company | Income may be characterised as corporate profit and salary rather than self-employment earnings | Israeli corporate compliance, payroll, accounting cost, and a set of US anti-deferral rules for owning a foreign corporation that are their own significant problem |
| Operate through a US entity | Whether anything changes depends on the entity type and its tax elections; do not assume forming one alters the SE tax | US filing obligations, possible Israeli tax residence of the entity, and cost |
The middle option is the one most often suggested casually in forums and it is the one with the largest hidden US complexity, because a US person owning a foreign corporation can walk into anti-deferral reporting that is worse than the tax they were avoiding. Say so, name it as outside this skill's scope, and refer it to a cross-border professional. Never present incorporation as a clean fix.
Stage 5: Produce the worksheet
Output: the projected SE tax for the year with each step shown, the Additional Medicare Tax position as a separate Form 8959 line, the amount to set aside per invoice, the instalment dates still ahead, and a short list of questions for a preparer (including which safe-harbor test applies). State which year's wage base you used and where it came from.
Do NOT use this skill for
- Deciding whether to incorporate, in Israel or the United States. That is exactly the decision that needs a licensed cross-border adviser.
- Anti-deferral rules for a US person owning a foreign corporation. Out of scope, and named here so it is not treated as covered.
- Annual filing mechanics, deadlines, FBAR, Form 8938, or the exclusion versus credit choice

Gotchas
- Saying the foreign earned income exclusion covers it. It does not touch SE tax. This is the central error in the domain and an agent that repeats it causes real financial harm.
- Applying 15.3 percent to full net earnings. Schedule SE multiplies by 92.35 percent first. Skipping that step overstates the bill by roughly 8 percent.
- Forgetting the social security wage base, or reusing last year's. The 12.4 percent portion stops at the base and the 2.9 percent Medicare portion does not. An agent that caps both, or caps neither, gets high earners badly wrong.
- Treating the SE tax deduction as reducing the SE tax. It reduces adjusted gross income for income tax purposes only.
- Assuming a totalization agreement exists because most developed countries have one. Thirty countries have one and Israel is not among them. Check the list rather than generalising.
- Recommending an Israeli company as the fix. It moves the problem into US anti-deferral territory for owners of foreign corporations, which is out of scope here and frequently worse. Present options, never a recommendation.
- Confusing the filing extension with a payment extension. Estimated payments are due during the year and interest runs regardless of any extension to file.
- Folding Additional Medicare Tax into SE tax. It is figured on Form 8959, and the line 13 half-deduction applies to the SE tax only.
- Ignoring US wages. Social security wages on a Form W-2 use up the wage base first, and a spouse's income counts toward the joint Additional Medicare threshold.

Troubleshooting
| Symptom | Cause | What to do |
|---|---|---|
| The user insists the exclusion means they owe nothing | The exclusion reaches income tax only | Quote the Schedule SE instruction directly. It is the fastest way to settle it, and it is in Reference Links. |
| The projection looks about 8 percent too high | The 92.35 percent step was skipped | Recompute following the Schedule SE order of operations. |
| A high earner's figure looks too high or too low | The wage base was applied to both portions, or to neither | The 12.4 percent social security portion is capped at the wage base. The 2.9 percent Medicare portion is not capped. |
| The user was told by a forum that an Israeli company solves it | It changes the characterisation but opens US anti-deferral rules for foreign corporations | Present it as one option with that cost named, decline to recommend, and route to a cross-border professional. |
| Two sources give different wage bases | The figure changes annually | Use the base for the tax year being computed and state which year it is. |
| The user asks what percentage of each invoice to save | Reasonable request, but it depends on their own numbers | Compute it from their projected net earnings and show the arithmetic. Do not quote a generic percentage. |
