How a calculator is built
Every calculator on Pashut Neto is built from two separate layers: one calculation engine that holds all the tax and benefit figures, and a content page that explains what the number means. The separation exists to prevent the most common failure in online calculators — a page that explains one year's tax brackets while calculating with another year's.
One source for every number
Every monetary figure on the site — income-tax brackets, the value of a credit point, National Insurance rates and their ceilings, purchase-tax brackets, allowances, the minimum wage and the training-fund ceiling — is defined in a single place in the code. No number on the site comes from anywhere else. That means updating one rate updates all 53 calculators in all five languages at once, and no page can be left behind.
Where the data comes from
The Israel Tax Authority — income-tax brackets, credit points, purchase tax, betterment tax and capital-gains tax. The National Insurance Institute — contribution rates for employees, the self-employed and employers, unemployment benefit, maternity allowance, reserve-duty compensation, child allowance and old-age pension, plus the wage report from which the salary percentiles are derived. The Central Bureau of Statistics — the consumer price index. The Bank of Israel — the base rate and mortgage data. Kol Zchut — summaries of employment rights: vacation days, sick days and recreation pay. The specific source for each calculator is linked at the bottom of that calculator's page, next to the explanation.
How we verify
Every figure is checked against its official source before publication, and again against a reference calculation worked out by hand for a defined test case — for example a gross salary of ₪15,000 for an employee with no additional credit points, or a mortgage at a known amount and rate. Those test cases are stored in the code and run before every new release; if a calculation drifts from its reference case, the release stops until it is resolved.
When the site is updated
A full refresh runs every January, when the tax brackets and rates for the new tax year are published. During the year, interim updates follow every legislative change or order — that is how the site was updated for Amendment 288 to the Income Tax Ordinance (March 2026) and for the minimum wage that took effect in April 2026. The date of the last update is shown at the top of every page, not only on the home page.
Simplifications we declare
A calculator is a model, and a model always gives something up. Rather than hide those trade-offs, we write them into the page itself. The betterment-tax calculator shows a nominal gain and does not index to the CPI; the self-employed net calculator does not account for the 52% deduction of National Insurance contributions or for pension deposits; the reserve-duty calculator does not include the partial-week rule; and the new-immigrant credit-point calculator shows the full three-point tier. Each such simplification appears on the relevant page itself, not in a footnote.
What we do not do
We do not give advice, we do not rank financial products, we do not ask for identifying details and we do not store what you enter — the whole calculation runs in your browser and is sent nowhere. There is no sponsored content on the site, and the single affiliate link it contains is explicitly labelled.
Found a wrong number?
Found a figure that looks wrong? Write to support@pashutneto.co.il with the page address, the values you entered, the number you got and the number you expected — and a link to the official source if you have one. We check every message, correct where needed, and update the page's revision date.
