A Quick Tax Credits question please

Princess_Coupon

My income this tax year is considerable less than last year, so this years tax credits are being paid based on this years income. My question is about next year April 2012-13, next year my income will be considerable higher, so will next years tax credits be based the current years income, or the previous years (ie this year again).
