The First Amendment to the US Constitution guarantees religious freedom to churches. From colonial times and since the creation of the very first tax code, churches have always been exempt from federal income taxes. This is part of the guarantee of religious freedom. After all, what the government can tax, it can control and even ultimately destroy. That’s why the federal Tax Code contains an automatic exemption for churches as public charities. Churches also enjoy numerous other favorable benefits such as special rules in place to limit audits, and even state and local tax exemptions.
