Israel and the United States operate under significantly different tax systems. Israel determines corporate residency based on incorporation or the location of management and control, while the United States treats corporations as residents only if they are incorporated within U.S. jurisdiction. Many growing companies misunderstand these distinctions or assume treaty protections that do not apply, leading to unexpected tax exposure. Importantly, there is currently no fully operative income tax treaty that eliminates withholding obligations between Israel and the U.S., meaning cross-border payments are generally subject to full domestic withholding rates (approximately 23% in Israel and 30% in the U.S.).

This article outlines the most common mistakes companies make when operating between Israel and the U.S., focusing on residency, permanent establishment, transfer pricing, withholding taxes, R&D incentives, and compliance.

Tax Residency

Corporate residency is one of the most critical factors in determining tax obligations.

In Israel, a company is considered a tax resident if it is incorporated in Israel or if its business is managed and controlled from Israel. In contrast, under U.S. tax law, a corporation is considered a U.S. tax resident only if it is incorporated in the United States.

A common mistake is misunderstanding how these rules apply in practice. For example, a company incorporated outside Israel but managed from Israel may still be treated as an Israeli tax resident. Similarly, any entity incorporated in the United States is subject to U.S. taxation on its worldwide income.

Failing to correctly determine residency can result in double taxation, reporting errors, and penalties.

Permanent Establishment (PE) / U.S. Trade or Business

Permanent establishment (PE) determines whether a foreign company has sufficient presence in a country to be taxed there.

Israel applies relatively broad PE rules. A fixed place of business, a dependent agent, or even significant local activity directed at the Israeli market may create a taxable presence.

In the United States, foreign companies are taxed on income that is “effectively connected” to a U.S. trade or business (ECI). This can include activities such as having employees, agents, or ongoing commercial operations in the U.S.

A major mistake is assuming that limited activity-such as sending employees for meetings, hiring remote workers, or conducting sales through agents-does not create a taxable presence. In reality, these activities can trigger tax obligations in either country.

Transfer Pricing and Documentation

Transfer pricing governs how transactions between related entities are priced.

Companies must ensure that all intercompany transactions follow the arm’s-length principle, meaning they reflect prices that unrelated parties would agree upon.

Key mistakes include:

1. Lack of documentation: Companies often fail to prepare proper transfer pricing studies on time. In the U.S., insufficient documentation can lead to significant penalties.
2. Incorrect pricing methods: Using inappropriate or inconsistent methodologies may lead to tax adjustments.
3. Weak comparables: Selecting non-comparable companies or manipulating benchmarks can raise red flags during audits.

In Israel, companies must report intercompany transactions annually, while U.S. regulations require contemporaneous documentation to support pricing decisions.

Withholding Taxes

Withholding taxes are a major source of unexpected costs in cross-border operations.

In Israel, payments to non-residents are generally subject to withholding at the corporate tax rate (around 23%) unless a specific exemption certificate is obtained.

In the United States, payments of certain types of income-such as dividends, interest, and royalties-are generally subject to a 30% withholding tax when paid to foreign entities.

Common mistakes include:

1. Assuming reduced treaty rates apply when they do not
2. Failing to obtain required documentation (e.g., W-8 forms)
3. Misclassifying payments, leading to incorrect withholding

As a best practice, companies should assume full domestic withholding applies unless they have formal approval for a reduced rate.

R&D Incentives

Both Israel and the United States offer tax incentives for research and development, but the rules differ significantly.

In Israel, R&D expenses are generally deductible when approved by the relevant authority. Starting in 2026, qualifying companies are expected to benefit from a direct tax credit of approximately 25%–30% for eligible R&D activities.

In the United States, the federal R&D tax credit provides a benefit of approximately 20% (or 14% under simplified methods) for qualifying research expenses.

A common mistake is misunderstanding the territorial nature of these benefits. The U.S. credit applies only to R&D conducted within the United States. Expenses incurred in Israel do not qualify for U.S. credits.

Companies operating in both countries should carefully plan where R&D activities are conducted to maximize available incentives.

Documentation and Compliance

Strong compliance practices are essential for avoiding penalties and audits.

Key requirements include:

1. Residency documentation: Maintain records of management decisions and board meetings
2. PE analysis: Continuously assess operational activities in each country
3. Transfer pricing records: Keep agreements, studies, and supporting data
4. Withholding documentation: File appropriate forms such as W-8BEN-E or local certificates
5. R&D tracking: Separate qualifying expenses by jurisdiction
6. Regulatory filings: Submit required forms in both Israel and the U.S. on time

Failure to meet these requirements can result in significant financial and legal consequences.
