There is an unusual interplay between federal and state laws. While states have the ability to enact their own laws, when there is a conflict, federal laws control. For example, medical marijuana dispensaries are a completely legal business in California. However, federal law still considers marijuana a controlled substance regardless of the purpose for which it is used.
As discussed in the previous post, one may consider simply surrendering when the IRS comes calling with news of a tax audit and/or informs you that you owe money to the federal government. Just because the IRS says you owe money, however, it does not mean they are right.
If the IRS comes calling, you will probably wonder whether you should simply surrender or put up a fight. While listening to your gut instincts could help, you'll definitely want to think your next moves through before taking action -- or inaction.
