I was also billed in December with box 7 checked but paid in January...however I input the full amount as reported on the 1098-T on last years return(2014). Can I claim the amount I paid in spring 2015 on this years return even though I guess I accidentally claimed it in 2014? I'm pretty sure my deduction wasn't maximized last year and the difference wouldnt have mattered but I'm not sure. If he didn't prepare his own taxes its likely the person who did, made the mistake I did and claimed the reported amount on the 1098 isn't it?
