Many people find the process of filing tax returns to be complex. It is therefore not surprising that many people make errors on their tax returns. In order for the IRS to bring charges of tax fraud or tax evasion against you, they must prove beyond a reasonable doubt that you intended to defraud the government of the money you owed in taxes. This means that they must prove that the error on your tax returns was in fact intentional. This can be difficult to prove. Prosecuting a taxpayer is also an expensive process. In many cases, the IRS will simply adjust the amount to what you owe in tax. They may also impose penalties. Attorney John Brennan is skilled and experienced in representing criminal defense clients.
