I receive regular requests from missionaries for a referral to a qualified CPA with experience in missionary tax returns. It’s a complex, difficult speciality, and one that doesn’t pay that well. CPAs have to master this field out of passion for missions.
I’ve posted a page listing CPAs who’ve posted here saying that this is what they do. I can make no recommendation, and I’m not familiar with all the CPAs listed. Therefore, you should make certain that these or any other CPAs you choose to use are familiar with the material posted here on the peculiar tax problems of missionaries.
And never, ever use a tax preparer who is not a CPA. Most CPAs don’t know this material. No store-front services do. Find someone who can help you do it right.
