When must I pay advance income tax as a self-employed person in Israel?

Self-employed individuals make monthly advance tax payments (avansim) to the ITA — typically between 4% and 16% of monthly gross turnover, depending on the rate the ITA assigns based on prior-year profitability. Payments are due by the 15th of the following month via the ITA online portal, bank transfer, or any Israeli post office. If income drops significantly, you can request a lower rate from the ITA during the year. Late avansim accrue interest and CPI linkage charges from the due date.
