Answer
(Fatwa: 1320/884/H=1433)
Zakah is not wajib only on the amount deposited in the account rather if you have other wealth entitled to zakah then it too shall be calculated while paying zakah. If you have no money and zakah wealth before, then write the day of March on which you had the money along with the Arabic date of the same day and the next year when the same Hijri date of approaches know the ruling of zakah by writing the complete detail of income and expenditure, then in-shaAllah we shall write complete ruling. If this year i.e. 2012 before March you have no money and zakah wealth then it is not wajib on you to pay zakah now.
