Zakat And Tax
There are different kinds of Zakat. Zakat on savings is 2.5%. Zakat on production is 5 or 10 percent, depending upon whether the production involves both capital and labour or only labour or capital. If it is either of capital or labour, the Zakat is 10% of the gross production. Things of use are exempted, therefore, Zakat on jewelry that is used occasionally is exempted. Its lesser use is still a use. Taxes are counted as Zakat paid. In your case, you are already paying more than the Zakat due on your salary.
