State tax filing

Please be careful here  I suggest that we understand the type of letter you received.  Such letters are usually designated as "CP-xxxx"

Many of the correspondences sent by the IRS are giving you a certain number of days in which you must respond to the letter with your agreement or disagreement, and details as requested.  Let us know the exact nature of the letter you received.  Here is an explanation of one of the common types of letters sent:
  
IRS CP 2000 Notice: Automatic Adjustment Notice – This is one of the most common automated adjustment notices. This notice will show proposed changes to your tax return. The information the IRS uses when sending these out is when it compares income, payments, credits, and other deductions reported on your tax return with information provided by third parties. Be careful with this notice because many times they are wrong. If you agree, you can agree and pay the amount owed. If you don’t agree you can call the IRS or contest it in writing. If you don’t contest within 60 days then the IRS will make the adjustment final within 60 days.
