Federal refund position = tax withheld + credits + additional payments - estimated federal tax. Positive means refund; negative means amount owed.
This calculator is an estimate only. Actual federal tax results may differ because of tax year, filing status, income classification, brackets, credits, phaseouts, deductions, and official rules.
