Tax liability in accounting refers to the amount of tax that a company or individual owes to the government based on their taxable income. It represents the total tax expense or obligation that needs to be paid to the tax authorities. Tax liability is calculated by applying the applicable tax rate to the taxable base, which can vary depending on the type of tax and its regulations. This liability is recognized as a current liability on the balance sheet until it is paid to the authorities. It is essential for businesses to accurately calculate and report their tax liabilities to comply with tax laws and fulfill their financial obligations.
