(1) Can income tax be paid from interest money received from private, and Govt Banks both?
(2) As income tax is deducted from my salary and remaining amount is deposited to my account, can I use the interest received from bank, if it is less than income tax already paid for that particular year?
بسم الله الرحمن الرحيم
As much amount is deducted in income tax you may use that much amount from the interest money which you have received from the bank. But it shall be necessary to maintain its accurate account lest the amount of actual interest should come into your personal use; therefore it should be avoided.
Allah knows Best!
