I was wondering if any traditional ANG or Reserve folks know what (if any) benefits a traditional guardsman gets for tax purposes. I was thinking per-diem and mileage for starters. Any one have an accountant in Maryland you recommend. Thanks in advance.

This may be old:
Military reservists travel expenses. If you are a member of the National Guard or military reserve, you may deserve a deduction for travel expenses to drills or meetings. To qualify, you must travel more than 100 miles and be away from home overnight.

If you qualify, you can deduct the cost of lodging and half the cost of your meals, plus 44.5 cents a mile (and any parking or toll fees) for driving your own car. You get this deduction regardless of whether you itemize.
