Is Zakat obligatory on a sum of 30,0 Egyptian Pounds deposited in the bank for two years, knowing that its owner is unemployed and has no expertise?

The obligation of Zakat (definition) is tied to complete ownership and the passing of a full year (hawl) on a complete nisab (definition), not to reaching puberty or maturity. If the aforementioned council is your guardian and pays Zakat on your behalf from your wealth, then that suffices for you as long as you are under their guardianship. However, after you are freed from guardianship, you are responsible for paying Zakat on your wealth for the two years mentioned. Zakat becomes obligatory on wealth if it reaches the nisab and a full year has passed over it. If the council was not paying Zakat, then request a statement for your balance and pay Zakat for each year separately if the hawl passed on the nisab. If the bank is interest-based (ribawi), then pay Zakat on the principal amount and dispose of the interest by spending it on charitable causes. The nisab is the equivalent of 85 grams of gold or 595 grams of silver, and the amount due is one-quarter of one-tenth (2.5%).
