The 2026 Worldwide Disclosure Regime: Mechanics and Implications for Olim
Inside the Israeli Tax Authority's worldwide income and asset disclosure regime, effective January 1, 2026 — what new olim must report, how the existing 10-year foreign-source exemption interacts with the new disclosure requirement, and the structural implications for UHNW principals.
Per the Israeli Tax Authority and Knesset Finance Committee filings, the worldwide disclosure regime took effect on January 1, 2026 as a structural component of the broader 2026 aliyah tax reform. The reform package operates on three layers, of which disclosure is the third and most operationally consequential for incoming UHNW principals.
The framework
The reform package, approved by the Knesset Finance Committee in March 2026 and embedded in the 2026 state budget, contains three layers.
Layer one — a five-year capped income-tax exemption on Israeli-source earned income for new olim and returning residents arriving between November 5, 2025 and December 31, 2026. Per Herzog Fox & Neeman analysis: ₪600,000 in 2026, ₪1,000,000 each year in 2027 and 2028, ₪350,000 in 2029, ₪150,000 in 2030.
Layer two — the unchanged 10-year exemption on foreign-source income.
Layer three — the new worldwide disclosure regime. From January 1, 2026, new olim and returning residents must report worldwide income and foreign assets to the Israeli Tax Authority. The exemption preserves the foreign-source tax position. The reporting privacy that prior cohorts enjoyed does not survive the reform.
What disclosure requires
Per ITA guidance and the Herzog Fox & Neeman and Meitar advisory layer, the disclosure regime requires reporting of:
- Worldwide income across all jurisdictions and sources, including business income, investment income, rental income, royalties, pensions, and trust distributions.
- Foreign financial accounts, including bank accounts, brokerage accounts, custody accounts, and the trust-held positions that prior olim cohorts could maintain without Israeli disclosure.
- Foreign real estate holdings.
- Foreign trusts, foundations, and discretionary structures of which the new oleh is settlor, beneficiary, or controller.
- Foreign company ownership interests above specified thresholds.
The exemption preserves the tax position. The disclosure is operational only — the ITA receives the data; no Israeli tax is owed on the foreign-source income during the 10-year exemption period.
Why this matters
For UHNW principals, the disclosure regime materially changes the structural calculus of aliyah.
Prior cohorts (those arriving before January 1, 2026) could maintain offshore structures with minimal Israeli reporting interface. Foreign trusts, holding entities, and broker-custody positions operated as a private offshore architecture during the 10-year exemption period.
Post-January 1, 2026, the same structures still benefit from the 10-year tax exemption. But they appear in Israeli reporting. The privacy layer is removed.
For some principals this is operationally inconsequential. For others — particularly those operating cross-jurisdictional family-office structures with sensitive privacy considerations — the regime reshapes structuring decisions and requires pre-aliyah restructuring documented before, not after, Israeli tax residency.
What advisory practice recommends
Per Herzog Fox & Neeman, Yigal Arnon-Tadmor Levy, Meitar, and Goldfarb Gross Seligman published commentary, the disclosure regime increases the importance of pre-aliyah cross-jurisdictional restructuring. Trust restructuring, holding-company consolidation, and the documentation of pre-aliyah asset positions all need to be completed before Israeli tax residency establishes.
The advisory tier has expanded substantially through 2024-2026 to support the cohort of UHNW principals navigating the reform window.
