<prompt> Human: I lived in Philadelphia for 2 years from Fall 2010 to fall 2012. I was jobless for the first 5 months or so until I started walking dogs, which I did until I moved to Vermont in 2012.I just received a notice in the mail from Berkheimer Tax Administrator saying I owe 237.27 for taxes to the Commonwealth of PA for the tax year 2011. It says I owed 168.28 in taxes, but that I paid nothing to the local tax collector. It also adds on a 43.98 penaltyinterest and 25.00 failure to pay cost.The details: I was an independent contractor while walking dogs, so I paid a LOT in taxes come april fortunately Im frugal to a fault and saved about 12 of what I earned. According to this notice I earned 16,829.00. I see in my bank statements that I paid over 3,000 in federal taxes, and 581 to the PA department of revenue. I thought I had paid all I needed to pay, so this notice comes as somewhat of a surprise. Im not the most organized person, so its totally possible I missed something, but I want to be sure before I mail a check off, do I actually owe money? Did I miss taxes somewhere?  <response>: You probably missed the annoying local tax.
