Here's the situation. My tax refunds are offset every year due to arrears in child support,which is fine,I owe it so I'm not arguing. My question is,my wife started working earlier this year and actually did make more than I, so I am wondering the best way to file our taxes so that she get's all that it due to her, the EIC, plus our child tax credit for our 3 children. We have been witholding from our paychecks hers/0 and mine/4. Can anyone tell me if this is the correct way to withold and which way to file? I understand filing joint will take longer for her to get her refund(due to the Injured Spouse form),but is it to our benefit to do this or file seperate? Thank you in advance
