Israeli Stock Options Tax Calculator

Problem

Israeli tech employees receive stock options or RSUs as a significant part of their compensation, but most have no idea how much tax they will actually pay when they exercise or sell. The rules under Section 102 are complex: different tracks (capital gains vs income), a 24-month trustee holding period, surtax thresholds, and Bituach Leumi interactions all affect the final number. Getting it wrong can mean paying tens of thousands of shekels more than necessary, or worse, facing unexpected tax bills at exit.

Instructions

Step 1: Identify the Grant Type

Ask the user what type of equity they hold:

Grant Type	How It Works	Common In
Stock options (ISOs)	Right to buy shares at a fixed strike price	Private startups
RSUs (Restricted Stock Units)	Promise to receive shares upon vesting, no strike price	Public companies, late-stage startups
Restricted shares	Actual shares with vesting restrictions	Founders, early employees

Also determine:

• Grant date (affects 24-month clock)
• Exercise price / strike price (for options; 0 for RSUs)
• Fair market value (FMV) at grant date (critical for RSU split calculation)
• Current FMV or expected exit price (for tax modeling)
• Number of shares/options
• Vesting schedule (standard: 4 years with 1-year cliff)

Step 2: Determine the Tax Track

Section 102 of the Israeli Income Tax Ordinance (Pkudat Mas Hachnasa) offers several paths. The track is chosen by the COMPANY when setting up the ESOP plan. Employees cannot choose their track after the fact.

Track	Tax Rate	Holding Period	Employer Deduction	When Used
102 Capital Gains (Honi)	25% flat on entire gain	24 months from grant via trustee	No	Most common. Best for employees
102 Income (Peiroti)	Marginal rate (up to 47%)	24 months from grant via trustee	Yes	Rarely chosen. Benefits employer
102 Non-Trustee	Marginal rate (up to 47%)	None	Yes	Uncommon. No trustee required
3(i) (non-102)	Marginal rate (up to 47%)	None	Yes	Foreign companies without 102 plan, non-compliant plans

Key questions to determine the track:

• Does the company have an approved Section 102 plan filed with the ITA? If no, it is 3(i).
• Is a trustee (ne'eman) holding the options/shares? If no trustee, it is 102 Non-Trustee or 3(i).
• Which track did the company elect: capital gains (honi) or income (peiroti)? Check the grant letter or ask HR.

The 24-month rule: Under both 102 trustee tracks, the trustee must hold the options AND the exercised shares for at least 24 months from the END OF THE TAX YEAR in which the options were granted. If the employee sells before 24 months, the entire gain is taxed as employment income at marginal rates. This is the most expensive mistake an employee can make.

Correction for common misconception: The 24-month period starts from the GRANT date (not the vesting date or exercise date). If options were granted on March 15, 2024, the earliest sale date for capital gains treatment is March 15, 2026.

Step 3: Calculate Tax per Track

Track A: Section 102 Capital Gains (Honi)

This is the most favorable track for employees. The entire gain is taxed at 25% flat (or 30% for controlling shareholders with 10%+ holdings).

Gain = Sale Price - Exercise Price
Tax = Gain x 25%
Surtax = (only if total annual income > 721,560 NIS)
  - 3% surtax on all income above threshold
  - 2% additional surtax on capital income above threshold
  - Total surtax rate: 5% on capital gains above threshold
Net = Sale Price - Exercise Price - Tax - Surtax

No Bituach Leumi applies on the capital gains track.

Controlling shareholder exception: If the employee holds (or held at any point) 10% or more of the company's shares, the capital gains rate is 30% instead of 25%.

Track B: Section 102 Income (Peiroti)

The gain is split into two parts:

Employment Income = FMV at exercise date - Exercise Price
Capital Gain = Sale Price - FMV at exercise date

Tax on Employment Income = Marginal income tax rate (10%-47%)
  + Bituach Leumi (up to 7% employee share)
  + Health Insurance (up to 5%)

Tax on Capital Gain = 25% flat

Surtax: 3% on all income above 721,560 NIS/year
  + 2% on capital income above 721,560 NIS/year

Track C: Section 3(i) / Non-102

Entire gain taxed as employment income at marginal rates. No capital gains portion.

Gain = Sale Price - Exercise Price
Tax = Marginal income tax (10%-47%)
  + Bituach Leumi (up to 7%)
  + Health Insurance (up to 5%)
  + 3% surtax if above threshold

RSU-Specific Calculation

RSUs under Section 102 capital gains track are taxed identically to options, but with exercise price = 0:

Gain = Sale Price - 0 = Sale Price (entire value is gain)
Tax = Gain x 25%

For RSUs under income track or listed companies, there is a split:

Employment Income = FMV at vesting date (or 30-day average for listed shares)
Capital Gain = Sale Price - FMV at vesting date

Step 4: Income Tax Brackets (2026)

When calculating marginal tax on the employment income portion (income track, non-trustee, or 3(i)):

Monthly Income (NIS)	Annual (NIS)	Rate
Up to 7,010	Up to 84,120	10%
7,011 - 10,060	84,121 - 120,720	14%
10,061 - 19,000	120,721 - 228,000	20%
19,001 - 25,100	228,001 - 301,200	31%
25,101 - 46,690	301,201 - 560,280	35%
46,691 - 60,130	560,281 - 721,560	47%

Plus 3% surtax on annual income above 721,560 NIS (total top rate: 50%).

Important: Stock option income from a single exit event is added to the employee's annual salary. If an employee earns 30,000 NIS/month salary and exercises options with 500,000 NIS gain under the income track, their total annual income becomes 860,000 NIS, pushing them into surtax territory.

Step 5: Bituach Leumi on Employment Income Portion

Bituach Leumi (National Insurance) and health tax apply ONLY to the employment income portion (income track, non-trustee, 3(i)). They do NOT apply to capital gains track.

Component	Reduced Rate (up to 7,122/month)	Full Rate (7,122-47,465/month)
Bituach Leumi (employee)	0.4%	7.0%
Health Insurance (employee)	3.1%	5.0%
Total employee	3.5%	12.0%

Maximum monthly ceiling: 47,465 NIS. Income above this ceiling does not incur additional BL/health contributions. For a lump-sum option exercise, the employment income portion is spread over the vesting period for BL calculation purposes.

Step 6: Generate the Tax Comparison Report

Always produce a side-by-side comparison to show the employee the difference between tracks. Use this format:

=== STOCK OPTIONS TAX BREAKDOWN ===
Employee: [name]
Company: [company]
Grant date: [date]
Exercise price: [price] NIS
Sale/exit price: [price] NIS
Number of shares: [N]
Gross gain per share: [gain] NIS
Total gross gain: [total] NIS

--- CAPITAL GAINS TRACK (Section 102 Honi) ---
Capital gains tax (25%):       [amount] NIS
Surtax (if applicable):       [amount] NIS
Bituach Leumi:                 0 NIS
Health Insurance:              0 NIS
TOTAL TAX:                     [amount] NIS
NET PROCEEDS:                  [amount] NIS
Effective tax rate:            [rate]%

--- INCOME TRACK (Section 102 Peiroti) ---
Income tax (marginal):         [amount] NIS
Capital gains tax (25%):       [amount] NIS
Surtax (if applicable):       [amount] NIS
Bituach Leumi:                 [amount] NIS
Health Insurance:              [amount] NIS
TOTAL TAX:                     [amount] NIS
NET PROCEEDS:                  [amount] NIS
Effective tax rate:            [rate]%

--- DIFFERENCE ---
Additional tax on income track: [amount] NIS
Capital gains track saves:      [percentage]%

tax advisor (yo'etz mas) for binding guidance.

Step 7: Model Exit Scenarios

When the user is facing a potential exit, model multiple price scenarios:

Scenario	Exit Price	Gross Gain	Tax (CG Track)	Net Proceeds
Conservative	$X	NIS Y	NIS Z	NIS W
Base case	$X	NIS Y	NIS Z	NIS W
Optimistic	$X	NIS Y	NIS Z	NIS W

Convert USD to NIS using the BOI representative rate (sha'ar yatzig) on the exercise/sale date. Use the boi-exchange MCP server if available for current rates.

Step 8: Exercise Timing Considerations

Help the employee think about WHEN to exercise:

Strategy	Pros	Cons
Early exercise (exercise before exit, start 24-month clock)	Locks in lower FMV as cost basis. Starts the 24-month clock earlier.	Requires paying exercise price out of pocket. Risk if company fails.
Exercise at exit (exercise and sell simultaneously)	No out-of-pocket cost. Guaranteed liquidity.	If 24-month period has not elapsed, entire gain is taxed as income.
Staged exercise (exercise in batches over multiple tax years)	Spreads income across years, may avoid surtax.	Complexity. Multiple 24-month clocks.

Critical warning for early exercise: If the employee exercises options early (pays the exercise price to get shares), they must ensure the trustee continues to hold the shares for the full 24-month period from grant date. Early exercise does NOT restart or shorten the 24-month clock.

Gotchas

1. 24-month clock starts at GRANT, not exercise. Agents commonly assume the holding period starts when options are exercised. It starts from the date the options were granted (or more precisely, the end of the tax year in which they were granted). Getting this wrong means telling the employee they can sell earlier than they actually can without losing capital gains treatment.

2. Surtax is 5% on capital gains, not 3%. Since 2025, capital income above 721,560 NIS/year is subject to both the 3% general surtax AND an additional 2% surtax on capital income. Agents often cite only the 3% figure. The correct combined surtax on capital gains above the threshold is 5%.

3. RSU "exercise price" is zero, not the grant-date FMV. For Section 102 capital gains track, the entire RSU value at sale is the taxable gain (since there was no purchase price). Agents sometimes mistakenly use the grant-date FMV as the cost basis, which understates the tax.

4. The employee cannot choose their track. The company selects the track (capital gains or income) when filing the 102 plan with the ITA. Agents sometimes present this as an employee decision. The employee can only optimize timing and amounts, not the track itself.

5. Foreign parent company shares have different rules. When an Israeli subsidiary grants options on the PARENT company's shares (e.g., a US-listed parent), Section 102 still applies if properly structured, but withholding and reporting mechanics differ. The employer must withhold tax at source upon sale, and Form 867 from the trustee may show different fields than domestic grants.

Troubleshooting

"I don't know which track my options are on"

Ask the employee to check their grant letter (kitvei haktzaa) or contact HR. The grant letter specifies "mislul honi" (capital gains track) or "mislul peiroti" (income track). If the company used a trustee (ne'eman), it is almost always the capital gains track.

"My company is foreign (Delaware C-Corp) with an Israeli subsidiary"

Section 102 applies to Israeli employees of Israeli companies. If the Israeli subsidiary is the employer and has a filed 102 plan, Section 102 applies to options on the parent's shares. If the employee is employed directly by the foreign parent, Section 3(i) applies instead.

"The exit is a stock-for-stock deal (not cash)"

In a stock-for-stock acquisition, the tax event occurs when the employee SELLS the acquired shares, not at the merger itself. The cost basis carries over. However, if the employee receives cash as part of the deal, that cash portion triggers an immediate tax event.

"I exercised before 24 months -- what now?"

The entire gain is reclassified as employment income, taxed at marginal rates (up to 47% + 3% surtax) plus Bituach Leumi and health insurance. This is significantly more expensive than the 25% capital gains rate. There is no way to reverse this.
