The income taxes to be paid in the near future are reported as a current liability.
If a corporation has overpaid its income taxes, the income taxes to be refunded by the government are reported on the corporation's balance sheet as a current asset.
There are also balance sheet accounts for deferred income taxes. Deferred income taxes arise when a revenue or expense item is reported on the income tax return in a year that is different from the year the item appears on the financial statements.
