"Religious employment" has 4 factors.
•You perform the sacraments
•You conduct services
•You are recognized as a leader by your congregation
•You play a role in guiding and administering church functions.
A pastor does not have to do all these things equally, the test depends on the facts of each case.
But, a person who works for a church in a non-clergy, non-pastor capacity is not a religious worker for tax purposes. Even an ordained minister who has been hired for non-religious duties (like a camp cook) is usually not entitled to be treated as a religious worker for tax purposes.
