When is the Zakat on salary obligatory for the first time?

Zakat is obligatory on salary if it reaches the nisab (the equivalent of 85 grams of gold or 595 grams of silver) and one hawl (lunar year) has passed on it. Its amount is 2.5%. Money given to the father for the purpose of savings is included in the nisab, but if it is a gift, it is not included. As for debts, they are deducted from the Zakat-eligible wealth if there are no corresponding assets for them. Zakat becomes obligatory on what remains after the deduction if it reaches the nisab.
