Should I pay income tax to Govt knowing that my money will be utilized in many things that are non halal.
بسم الله الرحمن الرحيم
(Fatwa: 376/388/B=5/1438)
The government shall be responsible for spending your tax and you shall not be sinful for it. Further, you pay income tax only owing to legal compulsion, hence Allah shall not question you about it.
Allah knows Best!
