<prompt> Human: How this happened, I do not know. Maybe rushing. I claimed a total of five exemptions, when I only meant one. Taxes have been taken from me each week, and while filling I still owed 1,500. This seems like a mistake. Any insight would be helpful. Total income from this w2 was 29,918 and taxes withheld were 1,100.  <response>: IRS employee here:Head on over to the Withholding Calculator at IRS.gov, and bring your recent paystub and a copy of your 2014 federal tax return.Be prepared to reduce your take-home pay by about 125 per month, if your wages remain about the same.The tool will help you complete a new Form W-4 to provide to your employer.Thank you for reading.
