What does a self-employed person pay in national insurance?

Advances now, the real bill at year end

What you pay through the year is advances against an estimated income, not the final charge. Once the assessment closes, Bituach Leumi compares the advances to the real liability and either refunds the difference or asks for it. A business whose income rose without updating the estimate gets that bill in one piece, usually the following year.

The estimate can be updated mid-year, which beats the surprise. The figure this calculator shows is the annual charge on the income you entered, so it is the number to hold your actual advances against.

Why the charge never reaches zero

Below ₪3,134 a month the charge is calculated on a minimum income, meaning as though you had earned that amount. While the file is open there is a payment, including in a month with no income at all. That makes closing a dormant file a financial decision rather than a bureaucratic one.

What comes back through income tax

52 percent of the national insurance contributions actually paid during the tax year is a recognized deduction against income tax. Health tax is not included. So part of the payment returns indirectly as a lower tax bill, and the figure shown here already accounts for it.
