When a taxpayer receives a notice from the IRS proposing an additional assessment of tax, the taxpayer can often work administratively with the IRS to resolve the dispute. However, many times, the taxpayer and IRS are not able to come to an agreement. In those instances, there are four different forums which can be utilized to litigate a Federal civil tax case: the United States Tax Court, United States District Courts, the United States Court of Federal Claims, and United States Bankruptcy Courts.
