Are the tithes to church to be given since state and irs taxes or after business expenses.?
Answers: You're being entirely too legalistic roughly speaking the tithe.
God doesn't need your money. The bible say that "The earth is the Lord's, and everything within it." He already owns it all. He doesn't NEED you to bequeath him money.
What tithing is really all in the order of is your heart. It's a mesaure of the value YOU put on your relationship beside God. Do you joyfully set aside ten percent of your income for God previously you concern yourself with other expenses, or not? (I don't...I hold a lot of growing to do surrounded by this area yet).
But I am convinced that this is a heart issue, not a money issue. It's in the region of the relationship, not the legalism.
Tithes to the church can be given before or after state taxes, irs taxes, and business expenses. You will not be penalize either course.
