body: I do know that in the US, bank-account interests are taxable as passive incomes, but what I don't understand is the point of filing tax returns on bank account interests, since the government (or the IRS), or whatever, has access to bank accounts and can directly deduct taxes (not seizing, I'm not talking about unpaid taxes or fraud istances), without henceforth requiring a tax return filing, since they could deduct the money themselves.
