What's in This Guide
Two Countries, Twice the Deadlines
If you're an American living in Israel, you already know the basic headache: you file taxes in two countries. But what catches most people off guard isn't the double filing itself. It's the sheer number of overlapping deadlines, each with its own extension rules, penalty structures, and procedural requirements.
The IRS expects its filings on the US calendar. The Israel Tax Authority (Rashut HaMisim) runs on the Israeli calendar. Neither cares about the other's schedule. And layered on top are FBAR deadlines from FinCEN, FATCA reporting through Form 8938, quarterly estimated payments to both countries, and bi-monthly VAT returns if you're self-employed in Israel.
The result: a typical American in Israel has somewhere between 8 and 15 separate tax-related deadlines per year. Miss one, and you could be looking at automatic penalties from $10,000 upward for certain information returns, or daily compounding interest from the IRS.
This guide maps every deadline for the 2026 tax year onto a single calendar. We cover what's due, when it's due, how to extend it, and what happens if you're late. Print it, bookmark it, share it with your accountant. It's the calendar we give every client at the start of each year.
Important Note on Tax Years
Both the US and Israel use the calendar year (January 1 through December 31) as the standard tax year. Most deadlines in 2026 relate to the 2025 tax year (income earned in calendar year 2025). We note exceptions where they apply. If you're self-employed in Israel, your bi-monthly VAT and advance tax payments relate to current-year (2026) activity.
Month-by-Month Calendar at a Glance
Here is every major deadline in one table. Scroll down for the visual timeline and detailed explanations of each.

Visual Deadline Timeline
The same deadlines, laid out month by month. Use this to see the clusters where multiple deadlines converge.
Document Collection
Israeli banks issue Form 867 (interest and dividend summary). Israeli employers issue Form 106 (annual salary statement, equivalent of W-2). US employers and financial institutions issue W-2s and 1099s. This is your window to gather everything before filing season begins.
US Pass-Through Entity Returns
S-Corp (Form 1120-S) and Partnership (Form 1065) returns due. You need the resulting K-1 to complete your personal 1040. If your entity files an extension, K-1s may not arrive until September, potentially delaying your personal return.
The Big Cluster: US Filing + FBAR + Estimated Taxes
Three things converge: US Form 1040 standard deadline (auto-extended to June 15 for overseas filers), FBAR original deadline (auto-extended to October 15), and Q1 estimated tax payment for the current year. Even with extensions, interest on unpaid US tax starts accruing from this date.
Israeli Form 1301 (Standard Deadline)
Individuals who are not represented by a CPA must file their Israeli annual return by April 30. If you have a CPA, the deadline is automatically extended to July 31. Most Americans in Israel use a CPA and benefit from this extension.
US Auto-Extension Expires + Q2 Estimated Payment
The automatic 2-month extension for Americans abroad expires. If you need more time, file Form 4868 by this date for an extension to October 15. Q2 estimated tax payment for 2026 income is also due.
Israeli CPA Extension Deadline
The most common Israeli filing deadline for Americans. Your CPA requests the extension through the Shaam system. Most individual returns are filed by this date. Further extensions to November 30 are available with approval.
US Final Extension + FBAR Final Deadline
Absolute last day for US return filing (with Form 4868). Also the final automatic FBAR extension deadline. After this date, any unfiled US returns are officially late, and penalties begin.
Israeli Final Extension
With special approval from the local Pakid Shuma (tax assessor), individual Israeli returns can be extended to November 30 or even later. This is not automatic and requires your CPA to negotiate with the tax office. Common for complex dual-filing situations.
Ongoing: VAT + Advance Tax Payments
Self-employed individuals (Osek Murshe) file bi-monthly VAT returns on the 15th of the following month. Advance income tax payments (Mikdamot) are due monthly or bi-monthly depending on your assessment. These are current-year obligations and run January through December.
US Deadlines Deep Dive
As a US citizen or green card holder, you file US taxes on worldwide income for life, regardless of where you live. Living in Israel changes some deadlines but not the fundamental obligation.
April 15: The Standard Deadline
This is the day US taxes are due, even if your filing deadline is later. The distinction matters: extensions give you more time to file, not more time to pay. If you owe money and don't pay by April 15, interest begins accumulating at the federal short-term rate plus 3%, compounded daily.
For 2025 tax year returns filed in 2026, the standard deadline is April 15, 2026.
June 15: Automatic Extension for Americans Abroad
If your tax home is in a foreign country and you live outside the US on April 15, you automatically get an extra two months to file (not to pay). No form is needed, but you must attach a statement to your return explaining that you qualified for the extension.
The June 15 Trap
Many Americans in Israel assume June 15 is their "real" deadline and don't think about April 15 at all. The problem: if you owe money, you're paying interest from April 15, not June 15. If you expect to owe more than a few hundred dollars, make an estimated payment by April 15 to stop the interest clock. Use IRS Direct Pay or EFTPS to pay electronically from abroad.
October 15: Final Extension (Form 4868)
By filing Form 4868 before June 15 (or April 15 for domestic filers), you get an automatic 6-month extension to October 15, 2026. This is the last possible filing date for most Americans. There is no further general extension beyond this.
Form 4868 is straightforward: your name, address, estimated tax liability, and total payments. You can file it electronically through IRS Free File, most tax software, or a tax professional. No reason or justification needed.
Form 2350: Special Extension for New Olim
If you've just made Aliyah and need extra time to meet the bona fide residence test for the Foreign Earned Income Exclusion (FEIE), Form 2350 lets you extend your return beyond October 15. This is specifically for expats who need to establish foreign residency for the full calendar year. It's rarely used after the first year of Aliyah but can be valuable in the transition year.
Quarterly Estimated Tax Payments
If you expect to owe more than $1,000 in US tax for the year and your withholding doesn't cover at least 90% of the current year's liability (or 100% of the prior year's), you must make quarterly estimated payments:
| Quarter | Period Covered | Payment Due |
|---|---|---|
| Q1 | Jan 1 - Mar 31, 2026 | April 15, 2026 |
| Q2 | Apr 1 - May 31, 2026 | June 15, 2026 |
| Q3 | Jun 1 - Aug 31, 2026 | September 15, 2026 |
| Q4 | Sep 1 - Dec 31, 2026 | January 15, 2027 |
Many Americans in Israel rely on the Foreign Earned Income Exclusion or Foreign Tax Credit to eliminate most US liability. If your credits and exclusions reliably cover your US tax, you may not need to make estimated payments. But if you have significant US-source income (rental properties, capital gains, retirement distributions), estimated payments are usually required.
Underpayment Penalties
If you don't make required estimated payments, the IRS imposes an underpayment penalty calculated on a quarter-by-quarter basis. The penalty is essentially interest at the federal short-term rate plus 3%. For 2026, that's likely in the 7-8% range annually. It's not catastrophic, but it adds up if you owe significant amounts.
Israeli Deadlines Deep Dive
Israel's annual tax return is Form 1301 (or the simplified Form 135 for salaried employees without complex income). The filing structure is less flexible than the US system but extensions are common, especially for CPA-represented filers.
April 30: Standard Individual Deadline
Individuals filing without professional representation must submit Form 1301 by April 30 for the prior tax year. In practice, very few Americans in Israel file by this date because most use a CPA and receive the automatic extension.
July 31: CPA Extension (Shaam System)
This is the deadline most Americans in Israel actually file by. When you're represented by a CPA who is registered with the Israeli Tax Authority, your CPA submits your filing through the Shaam (electronic filing) system. CPAs receive a quota of extensions, and the standard CPA extension pushes the individual filing deadline to July 31.
Your CPA handles the extension request. You don't need to file any forms yourself. The extension is granted to the CPA's practice, not to individual taxpayers, which means it's essentially automatic for all clients of a registered CPA firm.
November 30 and Beyond: Special Extensions
If the July 31 deadline isn't sufficient (common for Americans waiting on US tax documents, K-1s from partnerships, or complex cross-border calculations), your CPA can request a further extension from the local Pakid Shuma (tax assessor). Common extended deadlines:
- November 30: The most common second-tier extension for complex returns
- January-March of the following year: Available in exceptional cases, particularly when waiting for foreign tax information
These extensions are negotiated, not automatic. Your CPA needs a valid reason (waiting for US K-1, coordinating with US return, complex foreign income sourcing) and a relationship with the local tax office. This is one of the practical advantages of working with an experienced Israeli CPA.
Who Must File Form 1301?
Not every Israeli resident needs to file an annual return. You're required to file if:
- Your annual income exceeds a certain threshold (roughly 698,280 NIS for salaried individuals in 2025)
- You have income from two or more employers
- You have income from non-salary sources (investments, rental, business)
- You're a new oleh claiming the 10-year exemption on foreign income (disclosure required)
- You hold foreign assets above the reporting threshold
- You received a specific demand (Drishah) from the Tax Authority
As an American in Israel, you almost certainly fall into at least one of these categories. If you have US investments, a US pension, or US real estate, you have foreign income that triggers the filing requirement.

These are the reporting obligations that trip up more Americans in Israel than any other filing requirement. They're not about paying tax; they're about disclosing foreign financial accounts and assets.
FBAR: FinCEN Form 114
If the aggregate value of your foreign financial accounts exceeds $10,000 at any point during the year, you must file an FBAR. For Americans in Israel, this means virtually everyone: your Israeli bank account, kupat gemel, keren hishtalmut, brokerage accounts, and even your children's accounts all count.
| FBAR Detail | Information |
|---|---|
| Filing Form | FinCEN Form 114 (filed electronically through BSA E-Filing System) |
| Original Deadline | April 15 (same day as 1040) |
| Auto Extension | October 15 (automatic, no form needed) |
| Covered Accounts | Bank accounts, brokerage, kupat gemel, keren hishtalmut, pension funds, any account with a financial institution outside the US |
| Threshold | Aggregate value exceeds $10,000 at any time during the calendar year |
| Filed With | FinCEN (not the IRS, though the IRS enforces penalties) |
The FBAR is filed separately from your tax return, through a different system (BSA E-Filing, not IRS e-file). Many Americans in Israel don't realize the FBAR exists until years after arriving, by which point they have multiple years of unfiled FBARs and potential penalties totaling tens of thousands of dollars.
FBAR Penalties Are Severe
Non-willful failure to file: up to $10,000 per account per year. Willful failure: up to $100,000 or 50% of the account balance, whichever is greater, plus potential criminal prosecution. If you have 3 Israeli accounts and miss 3 years of FBARs, you could theoretically face $90,000 in penalties. The IRS Streamlined Filing Compliance Procedures can help if you weren't aware of the requirement. See our complete FBAR guide for details.
FATCA: Form 8938 (Statement of Specified Foreign Financial Assets)
Form 8938 is filed with your US tax return (attached to your 1040), so its deadline follows your 1040 deadline (April 15 / June 15 / October 15). The thresholds for Americans living abroad are higher than for domestic filers:
| Filing Status | End-of-Year Threshold | Any-Time-During-Year Threshold |
|---|---|---|
| Single, living abroad | $200,000 | $300,000 |
| Married filing jointly, living abroad | $400,000 | $600,000 |
Form 8938 overlaps significantly with the FBAR, but they are separate requirements. Filing one does not satisfy the other. The information reported is similar but not identical, and they go to different agencies (IRS vs. FinCEN).
The Key Difference: FBAR vs. FATCA
- FBAR: lower threshold ($10K), filed separately on BSA system, deadline April 15 (auto-extended to October 15)
- Form 8938: higher threshold ($200K+ for overseas filers), filed with your 1040, follows your 1040 deadline
- Both required: if you meet both thresholds, you file both. They're not alternatives.
Extension Procedures for Both Countries
Extensions are your best friend when you're filing in two countries with overlapping information needs. Here's exactly how to get them.
US Extensions
Automatic 2-Month Extension (No Form Needed)
If you're a US citizen or resident alien and your tax home is in a foreign country on April 15, you automatically get until June 15 to file. To claim it:
- Attach a statement to your return explaining that you qualified
- No form to submit in advance
- Interest still accrues from April 15 on any balance owed
- Late-filing penalty is waived until June 15
Form 4868: Automatic 6-Month Extension
File Form 4868 by June 15 (since you already have the 2-month auto-extension) to get an extension to October 15. This is:
- Automatic upon filing (no approval needed)
- Available to anyone, not just overseas filers
- Does NOT extend the payment deadline (interest runs from April 15)
- Can be filed electronically through IRS Free File or tax software
Form 2350: Extension to Meet Bona Fide Residence Test
This is specifically for Americans who recently moved abroad and need time to qualify for the FEIE's bona fide residence test (which requires tax home in a foreign country for an uninterrupted period including a full calendar year). It extends your return beyond October 15 to 30 days after you expect to qualify. Useful in your first year of Aliyah but rarely needed afterward.
Israeli Extensions
CPA Extension (Through Shaam System)
When you retain a CPA registered with the Israeli Tax Authority, your return is automatically included in your CPA's extension quota. The process:
- Your CPA registers you as a client in the Shaam system
- The Tax Authority grants the CPA a quota of returns that can be filed by July 31
- No separate application from you is needed
- The extension is to the CPA's practice, not to you individually
Further Extensions (Negotiated)
Beyond July 31, extensions require specific approval from the Pakid Shuma:
- Your CPA submits a request explaining why more time is needed
- Common reasons: waiting for foreign tax documents, complex cross-border calculations, K-1 delays from US partnerships
- November 30 is the standard second-tier extension
- Further extensions into the following year are possible but require strong justification
- The quality of your CPA's relationship with the local tax office matters here
Coordinating US and Israeli Extensions
The ideal sequence: file your Israeli return by July 31 using the CPA extension, then use the Israeli return data (foreign tax credits, income amounts) to prepare your US return by October 15 with the Form 4868 extension. This ensures the Israeli data flows cleanly into the US return. If your Israeli return is delayed beyond July 31, your US CPA may need to estimate Israeli tax amounts and amend later.
Penalties for Late Filing
Missing a deadline in one country is expensive. Missing deadlines in two countries simultaneously is doubly so. Here's what you're facing.
US Penalties
| Violation | Penalty |
|---|---|
| Late filing (Form 1040) | 5% of unpaid tax per month, up to 25% maximum. Minimum $510 for returns filed more than 60 days late. |
| Late payment | 0.5% of unpaid tax per month, up to 25% maximum. Runs alongside late-filing penalty. |
| Interest on unpaid tax | Federal short-term rate + 3%, compounded daily. Currently approximately 7-8% annually. |
| Failure to file FBAR | Non-willful: up to $10,000 per account per year. Willful: up to $100,000 or 50% of balance. |
| Failure to file Form 8938 | $10,000 initial penalty, plus $10,000 per month after 90 days of IRS notice (up to $50,000). |
| Failure to file Form 3520 (foreign trust reporting) | 35% of the gross value of trust distributions or 5% of gross value of trust assets. |
| Underpayment of estimated tax | Interest at federal short-term rate + 3%, calculated quarter by quarter. |
Israeli Penalties
| Violation | Penalty |
|---|---|
| Late filing (Form 1301) | Knas (fine) starting from the day after the deadline. Amount varies by assessment. Additional Ribit (interest) accrues on any tax due. |
| Late payment of tax | Hatzamada (linkage differential to CPI) + Ribit (interest) at approximately 4% annually, compounded monthly. |
| Failure to file at all | Criminal offense under Section 216 of the Income Tax Ordinance. Potential fine up to 226,000 NIS and/or imprisonment. |
| Late VAT filing | Knas of 219 NIS per two-week period (2025 rates). Plus interest on VAT owed. |
| Late advance tax payment | Hatzamada + Ribit from the original due date. Can trigger Drishah (formal demand) from Tax Authority. |
The Double Penalty Scenario
The worst situation: an American in Israel who ignores both countries' deadlines and has unreported foreign accounts. A single year of non-compliance could mean: $10,000+ FBAR penalty (per account), $10,000+ Form 8938 penalty, US late-filing penalties on unreported income, Israeli late-filing penalties and interest, and potential criminal exposure in both jurisdictions. We've seen total exposure reach six figures for a single year of inaction. If you're behind on filings, the IRS Streamlined Filing Compliance Procedures and Israeli voluntary disclosure programs can dramatically reduce these penalties.
Pro Tips for Staying on Track
After years of managing dual US-Israeli filings for American clients, here are the practices that consistently prevent missed deadlines and unnecessary penalties.
1. Use a Single Tax Calendar
Create one calendar (digital or paper) that includes every US and Israeli deadline. Color-code by country. Set reminders 30 days before each major deadline. The biggest filing failures we see happen not because of complexity but because a deadline simply wasn't on the client's radar.
2. File Israeli First, US Second
The ideal filing sequence: complete your Israeli return by July 31 (CPA extension deadline), then use the Israeli tax data to prepare your US return by October 15 (Form 4868 extension). This approach means your US return has accurate Israeli tax numbers for the Foreign Tax Credit, avoiding the need to amend later.
3. Pay Estimated US Tax by April 15
Even though you have an automatic extension to file, interest on unpaid tax starts April 15. If you expect to owe any US tax, send an estimated payment by April 15 using IRS Direct Pay. Overpaying slightly is better than underpaying and accruing months of interest.
4. Keep January-February Sacred for Document Collection
Treat January and February as your "gathering season." Israeli Form 867 and Form 106 arrive in January. US W-2s and 1099s arrive in January-February. If you're missing a document by mid-February, follow up immediately. Waiting until filing season to discover a missing document causes cascading delays.
5. Coordinate Your CPAs
If you use separate US and Israeli CPAs, make sure they communicate directly. The Israeli CPA needs certain US information (FEIE amount, FTC calculation) and the US CPA needs Israeli data (Israeli taxes paid, income categorization). Delays between CPAs are the number-one cause of missed extension deadlines.
Better yet: work with a single firm that handles both sides. It eliminates the coordination gap entirely.
6. Set Up Automatic VAT Filing (If Self-Employed)
Bi-monthly VAT is the deadline most frequently missed by self-employed Americans in Israel. Set up standing reminders every two months, or have your bookkeeper handle submissions automatically. The penalty per late filing is relatively small, but they accumulate fast and can trigger a tax audit.
7. Don't Wait for Perfection
It's better to file a return on time with a reasonable estimate and amend it later than to miss the deadline waiting for perfect information. Both the IRS and the Israeli Tax Authority allow amended returns (Form 1040-X in the US, Tikun Doch in Israel). An on-time estimate incurs zero penalty; a late return with perfect numbers still incurs penalties.
8. Keep a Running Tax Document Folder
Throughout the year, as you receive tax-relevant documents, drop them into a dedicated folder (physical or digital). By December 31, you should have most of what you need already organized. This turns January's document collection from a scramble into a review.

Schedule Your Free Consultation →Frequently Asked Questions
What happens if I miss the April 15 US tax deadline as an American in Israel?
Americans living abroad get an automatic 2-month extension to June 15 without filing any form. You must attach a statement to your return explaining you qualify. Interest still accrues from April 15 on any balance owed, but the late-filing penalty is waived until June 15. If you need more time beyond June 15, file Form 4868 for an extension to October 15.
When is the FBAR deadline for the 2025 tax year?
The FBAR (FinCEN Form 114) for the 2025 tax year is due April 15, 2026, with an automatic extension to October 15, 2026. No separate extension form is needed. Filing is done electronically through the BSA E-Filing System, not through the IRS e-file system used for tax returns.
Can my Israeli CPA extend my Form 1301 deadline?
Yes. CPAs registered with the Israeli Tax Authority through the Shaam system can request extensions for their clients. The standard CPA extension moves the deadline to July 31. Further extensions to November 30 or beyond are possible with approval from the local tax office (Pakid Shuma). These additional extensions require justification but are commonly granted for Americans with complex cross-border situations.
Do I need to file taxes in both the US and Israel every year?
Yes. US citizens and green card holders must file a US federal tax return (Form 1040) regardless of where they live. If you are an Israeli tax resident (which most Americans living in Israel are), you must also file an Israeli annual return (Form 1301) reporting worldwide income. The US-Israel tax treaty and Foreign Tax Credits help prevent double taxation on the same income.
What are the penalties for late FBAR filing?
Non-willful FBAR violations carry penalties up to $10,000 per account per year. Willful violations can result in penalties up to $100,000 or 50% of the account balance, whichever is greater, plus potential criminal prosecution. If you've missed past FBARs but weren't aware of the requirement, the IRS Streamlined Filing Compliance Procedures may allow you to catch up with reduced or eliminated penalties.
The Bottom Line
Living in Israel as an American means managing a complex web of deadlines across two tax systems. The good news: every single deadline is manageable with advance planning and the right professional support. The bad news: missing even one can trigger penalties that are wildly disproportionate to the underlying obligation.
The key takeaways from this calendar:
- April 15 matters even with the June 15 auto-extension. Pay estimated tax by April 15 to stop interest.
- Use the CPA extension on the Israeli side. July 31 gives you breathing room to coordinate both returns.
- File Israeli first, US second. Complete Form 1301 by July 31, then feed the data into your 1040 by October 15.
- Never skip the FBAR. The penalties for missing FinCEN Form 114 are catastrophically higher than anyone expects.
- Coordinate your CPAs. Or better yet, use a single firm that handles both sides.
