Deductions & credits

Thank you Opus. I didn't mean to reimburse same expense twice. Was thinking have my wife reimburse first half year of expense and I reimburse the second half. But as I read your response below, it seems we can each reimburse $2500 however, only one person can get the reduction in income. The other person's $2500 will be add back to income, which makes it as if it is paid with after tax dollars. Did I understand you correctly? I would not lose the $2500, but just have to pay income tax on it? Thank you.
