Before I'd rely on the IRS, I'd check with a group you belong to such as NAEA or NATP. Especially if you have a local chapter so already know which preparers might have similar clients. Jainen's suggestion to see a tax preparer is a good one. You need to find someone who you can sit with face-to-face or talk on the telephone or chat/IM in real time who prepares returns for civilian employees of the military overseas, in and out of war zones. They might mentor you for free, but even if you pay them for their time and oversight you'll get value for your money on your own return and develop a new niche for business. Start with who hired your husband; ask if he's heard where employees get their returns prepared. Have your husband talk to his new co-workers to ask the same question. Also, look for courses, probably online or pre-recorded, on the topic. Do searches on other message boards. Good luck to your husband and to you.
