When you get a letter from the IRS, what should you do? You should respond to the IRS letter appropriately. So many people reply to the letter with too much information! The IRS doesn’t care about your story, they only care about getting the money. Also, if you provide too much information you might be giving the IRS information that they can use against you. So, keep emotions out of it and respond appropriately. Of course we recommend that you allow your tax professional to respond for you.
