Does a church need to issue Forms 1099-MISC to all the missionaries it supports?
Missionary support will not require issuance of Form 1099-MISC when the support is sent to his or her mission agency. That agency is considered the employer of the missionary and will issue the proper forms. Only when the church acts as a missionary's agency, sending payments directly to the individual, will the church need to issue an information return and then only when the annual payments exceed $600. The church should request Form W-9 be completed by the missionary in these rare (my experience) occasions. Form W-9 is available on the IRS website.
