Your data stays yours. We don't share information with third parties.
This tool only estimates. Whether you go on to file is entirely your call.
Zkai is a private, independent venture - not affiliated with, and not acting on behalf of, the Israel Tax Authority.
Straight answers, no fine print.
Question we didn't cover? The check itself answers most of them in three minutes.
The check itself is completely free. You toggle a few questions and get an estimate - no credit card, no signup.
The Israel Tax Authority lets you file for a refund on the past six tax years. This year, for example, you can file for 2020–2025.
Any salaried employee who had income tax withheld - especially if you changed jobs, took maternity leave, finished the army or a degree, made donations, or have children.
Not to check. You'd only need an accountant or tax advisor if you decide to actually file - and even then it's not mandatory. Dedicated services can file for a flat fee.
Your data stays with us only, encrypted in transit and at rest, and never shared with third parties - not even with the Tax Authority. You can delete it anytime.
Once you file an annual return with the Tax Authority (yourself or through a service), the refund lands as a bank transfer to your account, typically within 60–90 days.
We're not the Tax Authority and don't act on its behalf. Zkai is an independent tool that helps you decide if it's even worth opening the process - before you invest time or money.
The check takes less than three minutes. No commitment, no cost.
