Should I Tithe on Gross or Net Income?
This is one of the most common questions Christians ask about giving. The Bible does not explicitly use the terms "gross" or "net" income, leaving this as a matter of personal conviction and interpretation.
Argument for Gross (Firstfruits)
Proverbs 3:9 says to honor the Lord with your "firstfruits". Many interpret this as giving from your total income before the government takes its share. It symbolizes putting God first, above all other obligations.
Argument for Net (Increase)
Others argue that "tithe" is on your "increase" (Deuteronomy 14:22). Since taxes are money you never actually possess or use, your true "increase" is what lands in your bank account (Net Income).
Key Considerations
- The Heart Matters More: 2 Corinthians 9:7 emphasizes giving cheerfully, not under compulsion.
- Old vs New Testament: While the tithe (10%) was an OT law, the NT principle is radical generosity.
- Practical Impact: Use the calculator above to see the actual financial difference. For many, the difference might be smaller than the spiritual peace of giving "off the top".
