"No, Jehovah’s Witnesses do not practice tithing; our work is financed by anonymous voluntary donations. What is a tithe, and why don’t Jehovah’s Witnesses practice tithing?
The commandment to tithe, or contribute a tenth of one’s belongings, was part of the Law given to the ancient nation of Israel. However, the Bible makes it clear that this Law—including the “commandment to collect tithes”—does not apply to Christians.—Hebrews 7:5, 18; Colossians 2:13, 14.
Rather than giving required tithes and offerings, Jehovah’s Witnesses imitate the early Christians and support their ministry in two ways: by performing their personal ministerial work without pay and by making voluntary donations.
We thus follow the Bible’s direction to Christians: “Let each one do just as he has resolved in his heart, not grudgingly or under compulsion, for God loves a cheerful giver.”—2 Corinthians 9:7.
