After you file

Okay so since there was a high fraud and people was using other people's w2 info (absolutely Ridiculous) they have to verify the employee and employers wedges and make sure they match... U can't give them info they have to investigate it on there own,To provent fraud . I know it seriously sucks. An honestly everybody is different on why they got a rev8ew your employer and wedges may be correct and u can get your taxes sooner then later maybe is just a simple mistake and they have to go in a adjust the amount . Could just be a simple fix. They just say up to 45 days unless they tell u 45 plus days..but if u get a letter look up the codes on Google. It could give u an idea.. not everybody will get a letter .
