NETO TAX GUIDE
Tax on additional income in Israel
How tax coordination, withholding and National Insurance affect your real net income from a second job or side project.
NETO lets the client receive an invoice while you receive a payslip and net salary.
Quick answer: additional income is taxed together with your annual income, not in isolation. Without tax coordination, a second payer may withhold too much. NETO helps employees and project workers understand whether a payslip, invoice route or business file is the right structure.
Tax on additional income Israel: quick answer
Tax on additional income Israel depends on your main salary, tax brackets and coordination with the tax authority and National Insurance. Before taking payment, check the net result and the cleanest reporting route.
Example: an employee earns NIS 14,000 per month and receives a NIS 3,500 side project. Without a tax coordination certificate, the payment may be withheld at a high default rate, hurting cash flow even if the final tax liability is lower.
Withholding
The payer follows the certificate available at payment time.
Real net
Final tax depends on annual income and credits.
National Insurance
Net pay includes more than income tax.
Plan early
Coordinate before the first payment when possible.

How additional income is taxed
Israeli income tax is calculated annually and progressively. Side income joins your main salary, tax credits and other income. The practical problem is withholding during the year: without the right certificate, a second payer may deduct more than your final tax liability.
Tax coordination prevents over-withholding
The Israel Tax Authority online service is intended, among others, for employees who receive wages from more than one employer and for small business owners. It is better to coordinate before payment than wait for a refund after the year ends.

National Insurance also affects net pay
National Insurance and health insurance depend on the payer route and personal status. A salary payslip, self-employed activity and other income can be treated differently, so a real net calculation should include both tax and National Insurance.
