Note 6. Income Taxes

Income tax expense in both 2023 and 2022 varies from the amount computed by applying the federal corporate income tax rates of 21% to income before income taxes, primarily due to state income taxes, net of federal income tax effect, adjusted for permanent differences the most significant of which is the effect of the per diem pay structure for drivers. Drivers who meet the requirements to receive per diem receive non-taxable per-diem pay in lieu of a portion of their taxable wages. This per diem program increases our drivers' net pay per mile, after taxes, while decreasing gross pay, before taxes. As a result, salaries, wages, and related expenses are slightly lower and our effective income tax rate is higher than the statutory rate. Generally, as pre-tax income increases, the impact of the driver per diem program on our effective tax rate decreases, because aggregate per diem pay becomes smaller in relation to pre-tax income, while in periods where earnings are at or near breakeven the impact of the per diem program on our effective tax rate is significant. Due to the partially nondeductible effect of per diem pay, our tax rate will fluctuate in future periods based on fluctuations in earnings.

Our liability recorded for uncertain tax positions as of  September 30, 2023 is unchanged since  December 31, 2022.

The net deferred tax liability of $102.7 million primarily relates to differences in cumulative book versus tax depreciation of property and equipment, partially off-set by net operating loss carryovers and insurance claims that have been reserved but not paid. The carrying value of our deferred tax assets assumes that we will be able to generate, based on certain estimates and assumptions, sufficient future taxable income in certain tax jurisdictions to utilize these deferred tax benefits. If these estimates and related assumptions change in the future, we may be required to establish a valuation allowance against the carrying value of the deferred tax assets, which would result in additional income tax expense. On a periodic basis, we assess the need for adjustment of the valuation allowance. The Company has determined that a valuation allowance was not necessary at September 30, 2023 for its deferred tax assets since it is more likely than not they will be realized from the future reversals of temporary differences. If these estimates and related assumptions change in the future, we may be required to modify our valuation allowance against the carrying value of the deferred tax assets.

On March 11, 2021, President Biden signed the American Rescue Plan ("ARPA") into law. The law includes several provisions meant to stimulate the U.S. economy. Of relevance to the Company, ARPA extended the reach of IRC Section 162(m) to include compensation paid to the eight highest-paid individuals other than the chief executive officer and the chief financial officers (rather than the three highest), however, this change is not effective until 2027. There is no material impact to the financial statements at this time.

President Biden signed the Inflation Reduction Act (the "IRA") into law on  August 16, 2022. We do not anticipate the IRA will have a significant impact on income tax expense or on other taxes. One of the most impactful provisions of the IRA includes the establishment of a Corporate Alternative Minimum Tax ("CAMT"). However, this tax only applies to corporations with three-year average earnings in excess of $1.0 billion. We will continue to monitor the CAMT each year to determine if we will become an applicable corporation. Additionally, the IRA enacted an excise tax on stock buybacks, which imposes a 1% tax on stock buybacks, subject to netting provisions regarding stock awarded to employees as part of their compensation. We do not believe this will have a material impact on our active buyback program, but will continue to monitor IRS guidance and regulations on how the buyback tax will be imposed and administered.

On May 11, 2023, the Tennessee Works Tax Act was signed into law by Governor Lee. The most impactful change for the Company was the phase-in of a single-sales factor apportionment formula for the logistics and leasing companies that file in Tennessee. The motor carriers already apply a single-sales factor. This resulted in the Company recording a $1.3 million benefit year to date through September 30, 2023.
