All calculations are based upon the most common tax deductions and credits for the typical taxpayer. Provided values are estimates only. In the case of more complicated tax returns, the provided values are usually underestimated. Actual federal tax liability will change slightly depending on state of residence, dependent age, and other deductions and credits taken.
