The Israeli government may tax resident companies as much as 25% on all income gained in a fiscal year. The capital gains tax is 20%. The value added tax in Israel is 16% (in 2010).
The fiscal year follows the Gregorian calendar, not the Jewish one. Businesses must file an annual audited tax return five months after the end of the fiscal year.
Israel has treaties with certain countries which prevent double taxation. For a list of these countries, consult Invest in Israel's website.
