How long does the Israel Tax Authority have to open or reopen a personal income tax assessment?

Under the Income Tax Ordinance (New Version) 5721-1961, the Israel Tax Authority has four years from the end of the tax year in which a return was filed to issue an additional assessment. If the authority finds evidence of income concealment or a material omission, that window extends to seven years. No limitation period applies where no return was filed at all for a year in which filing was required.

The assessment and reassessment powers of the Israel Tax Authority are set out in Sections 145 and 147 of the Income Tax Ordinance (New Version) 5721-1961. Section 145 empowers a tax officer to issue an additional assessment within four years of the end of the tax year in which the return was filed — for example, a return filed for the 2022 tax year can be reassessed until the end of 2026. Section 147 extends this window to seven years where the assessing officer has reasonable grounds to believe that income was concealed or that a material omission was made in the return. These are not negotiating positions; the ITA treats both periods as hard deadlines. Separately, if a taxpayer failed to file a return at all for a year in which filing was required, no limitation period applies and the ITA may issue an estimated assessment at any time. Appeals against any assessment must be filed within 90 days of receiving the assessment notice.

For foreign nationals who have spent time as Israeli tax residents — even briefly — or who have Israeli rental income or other locally sourced income subject to filing obligations, the four-year window has direct practical implications. A taxpayer who leaves Israel may receive an ITA assessment years after departure. All income records, expense documentation, and bank statements should be preserved for at least seven years to cover both the standard four-year window and the extended concealment window. New immigrants (olim hadashim) who benefit from the 10-year foreign income exemption must now report that foreign income from 2026 onward; any reporting error could trigger the seven-year period. ITA assessments are enforceable through direct bank account attachment powers under Section 194 of the Ordinance without a court order, making prompt response to any assessment notice essential — delays compound the exposure.
