hey guys,

i just tried doin my taxes for this year..i work at a factory so, i have my w2 form. I did my taxes the exact same way last year and got some money back but dont know what happened this year i owe them 1200 dollars..but the only difference is in 2007 I paid taxes for whole 12 months but this year I paid taxes for 6 months and exempted for the rest..does that make any difference does anyone know...please help...
