Credit recapture. If any tax-free educational assistance for the qualified education expenses paid in 2012, or any refund of your qualified education expenses paid in 2012, is received after you file your 2012 income tax return, you must recapture (repay) any excess credit. You do this by refiguring the amount of your adjusted qualified education expenses for 2012 by reducing the expenses by the amount of the refund or tax-free educational assistance. You then refigure your education credit(s) for 2012 and figure the amount by which your 2012 tax liability would have increased if you claimed the refigured credit(s). Include that amount as an additional tax for the year the refund or tax-free assistance was received.
