Tax liability is the total amount of tax you owe based on your taxable income, before subtracting withholding and estimated payments. Calculate by applying tax brackets to your taxable income, then subtracting credits. Subtract withholding and prepayments to determine your refund (negative) or balance due (positive). For high earners with large bonuses, RSU vests, or capital gains, projected tax liability often exceeds withholding — requiring estimated payments to avoid underpayment penalties. Track quarterly to avoid April surprises. Tax liability differs from cash flow impact: AMT, Net Investment Income Tax, and self-employment tax all add to liability beyond regular income tax.
