<prompt> Human: So I got whats probably a common letterform from the IRS in Georgia detailing how apparently I didnt pay taxes on all of my income. Whenever I fill out the I-9 ? I think thats the form name and where you say you want them to take taxes out of your paychecks right away so that I wouldnt have to deal with it later I always elect the highest amount so Im not sure why I might owe anything.I started work in Georgia, which has state income tax, in August 2011. I was release from the project I was on due to the project failing around January 2012. They kept me on while looking for another project in the company for me until May 2012, during which time I was still being paid. I found a position myself in Florida, which does not have state income tax, with another company and began receiving paychecks from them in January 2012 and was employed there until October 2012 and moved to my current company, still in Florida, that same month.In 2013 around this time I filed my taxes through Turbo Tax, including all of my W4s, and received a refund. I thought because of my election on the I-9 to pay the maximum in taxes, I would never have to deal with any of this anyways. How could I possible owe any money if I always payed it up front?Im not really sure what to make of the details included in the letter I received, but I think theyre trying to break down why I owe money based on income and tax payments. The letter says the Taxable income, line 27, shown on return is 11,000 less than as corrected by IRS. 11,000 is what I made from the first company in Georgia during 2012, but as far as Im aware, taxes were paid on that income each paycheck so... Im just really confused. I dont know how to justify that Ive already paid the taxes or even verify that I really did though again, I thought that with the I-9, I was saying pay all my taxes upfront.Assistant: The letter says the Taxable income, line 27, shown on return is 11,000 less than as corrected by IRS. 11,000 is what I made from the first company in Georgia during 2012, but as far as Im aware, taxes were paid on that income each paycheck You still have to declare it as taxable income - you just subtract the withholding from your taxes owed when you file. Did you include W-2s from both jobs when you filed last year? At this point, you should probably take the letter and your tax documents from 2012 to a tax professional.Human: What all tax documents should I have when going in to an office for a tax professional? Ive got my final pay statements from ADP for all 3 jobs I received money from in 2012. I dont think I can access my 1040-EZ or whatever form I used.Assistant: Anything you have from when you did your taxes last year. W-2s from every job at the very least.Human: I dont have those W-2s anymore, but maybe Ill be able to request them from my employers.The thing that just doesnt make sense to me is that I thought that my federal income tax is taken from me at each paycheck. On the W-4 I definitely wouldnt have tried to withhold any of the taxes as to avoid the situation Im in now.I thought that filing taxes each year was just so that if you did elect to not pay full taxes or have some other taxable income that youd pay that now or to receive a refund if you paid too much.If I chose to let the govt take all the taxes they want at first on my W-4, shouldnt I only ever have a 0 balance or receive a refund?  <response>: You definitely misunderstand how taxes work. Taking a little time to read up on the subject or just going through a program like TurboTax should help. If I chose to let the govt take all the taxes they want at first on my W-4, shouldnt I only ever have a 0 balance or receive a refund? No. Thats just setting aside money to help you pay your taxes in April. The government isnt deciding how much to withhold, you do.
