Biblical Answer

Tithing on gross or net income is a matter of personal choice, but the biblical principle is to tithe on gross income. In the Old Testament, the Israelites were required to bring 10% of their annual earnings to the Lord, which was based on their gross income. This principle is still relevant today, as the Bible teaches that we should give generously out of our "flock, threshing-floor, and wine press" (Deuteronomy 14:22-29). Tithing on net income may not accurately reflect our true income, as it may not account for deductions and expenses that are not directly related to our gross income.

However, it is also important to note that some Christian denominations and individuals may tithe on net income, and that is a legitimate choice. In fact, the Didache, one of the earliest books of the Christian community, suggests that it is acceptable to designate a portion of our tithe for the support of other Christian ministries that need our help. This means that we can tithe on our net income and still give to other ministries that are important to us. Ultimately, the key is to be generous and to give regularly, regardless of whether we tithe on gross or net income.

In conclusion, while the biblical principle is to tithe on gross income, it is ultimately a matter of personal choice. What is most important is that we give generously and regularly, and that we are faithful in our giving. As the Bible teaches, "Give generously out of your flock, your threshing-floor, and your wine press" (Deuteronomy 14:22-29). By doing so, we can experience the joy and discipline of tithing, and we can be a blessing to others through our generosity. The key is to be faithful and to give regularly, regardless of whether we tithe on gross or net income.
