Tax Liability. The amount of total tax due the IRS after any credits and before taking into account any advance payments (withholding, estimated payments, etc.) made by the taxpayer.
Unlike adjustments, exemptions and deductions, which apply to your income, tax credits apply to your tax liability (which means the amount of tax that you owe). For example, if you calculate that you have tax liability of $1,000 (based on your taxable income and your tax bracket) and you are eligible for a tax credit of $200,that would reduce your liability to $800. You would only owe $800.
