CTBI accounts for income taxes in accordance with income tax accounting guidance (ASC 740, Income Taxes).  The income tax accounting guidance results in two components of income tax expense:  current and deferred.  Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues.  CTBI determines deferred income taxes using the liability (or balance sheet) method.  Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur.  Deferred income tax expense results from changes in deferred tax assets and liabilities between periods.  Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized.

Uncertain tax positions are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination.  The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any.  A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information.  The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment.

With a few exceptions, CTBI is no longer subject to U.S. federal tax examinations by tax authorities for years before 2020, and state and local income tax examinations by tax authorities for years before 2019.  For federal tax purposes, CTBI recognizes interest and penalties on income taxes as a component of income tax expense.
