Tax liability
The amount calculated from taxable income before subtracting payments.
In one sentence
Tax liability is the result of the tax calculation, before withholding is reconciled.
Model
income tax + included additional taxes = tax liability
Worked example
If the calculation produces $8,400 of tax and $7,900 was withheld, liability is $8,400 and the estimated balance is $500 due.

Common misconception
A refund does not necessarily mean tax was low; it means payments exceeded the calculated liability.
