السلام عليكم When I was a student, I thought I didn’t need to pay zakat for a year or two, but later found out I was required to. I didn’t pay at the time. Do I estimate the zakat I owed then and pay that now, or do I pay zakat based on what I have now for both periods plus this year?

U estimate yes and u pay and u can ask the bank to provide u with how much u had at that time if your money was there.
