Zakat On Business Income
If the income is small, it should not be taxable. if it is taxable you have to pay 5% of it. The business is taken as a whole. You can count the tax you pay as Zakat. then there will be a very small amount to pay as zakat. However, if you think that the threshold of taxable zakat is not fair, then you can decide not to pay zakat on it with honesty and put your case before God in the hereafter.
