Is a benevolent payment made prior to an employee's start date taxable if that payment occurs in same calendar year as becoming an employee of the church?

If you want to DIY your payroll, I highly recommend you look at using Gusto! It is very user friendly and their support is awesome! Plus they know how to set up and maintain payrolls for churches and nonprofit organizations.

Note: I am a "partner" of Gusto, but as I have told you before ... I never recommend anything that we or our clients have not tried and love =)
