Income Taxes

Note 5. Income Taxes

ASC 740, Income Taxes, defines the threshold for recognizing the benefits of tax return positions in the financial statements as "more-likely-than-not" to be sustained by the taxing authority. This section also provides guidance on the derecognition, measurement and classification of income tax uncertainties, along with any related interest and penalties, and includes guidance concerning accounting for income tax uncertainties in interim periods.

The unrecognized tax benefit related to uncertain tax positions related to state income tax filings was $8.8 million at March 31, 2024 and December 31, 2023, respectively. During the three months ended March 31, 2024, Pinnacle Financial paid $3,000 in taxes related to state income tax filings for tax years prior to 2024. During the three months ended March 31, 2023, Pinnacle Financial paid $4.2 million in taxes related to state income tax filings for tax years prior to 2023.

Pinnacle Financial's policy is to recognize interest and/or penalties related to income tax matters in income tax expense. No interest and penalties were recognized during the three months ended March 31, 2024 and March 31, 2023.

Pinnacle Financial's effective tax rate for the three months ended March 31, 2024 was 18.1% compared to 19.8% for the three months ended March 31, 2023. The difference between the effective tax rate and the federal and state income tax statutory rate of 25.00% at March 31, 2024 and 2023, respectively, is primarily due to investments in bank qualified municipal securities, tax benefits of Pinnacle Bank's real estate investment trust subsidiary, participation in the Tennessee Community Investment Tax Credit (CITC) program, and tax benefits associated with share-based compensation and bank-owned life insurance, offset in part by the limitation on deductibility of meals and entertainment expense, non-deductible FDIC premiums and non-deductible executive compensation.

Income tax expense is also impacted by the vesting of equity-based awards and the exercise of employee stock options, which as expense or benefit is recorded as a discrete item as a component of total income tax, the amount of which is dependent upon the change in the grant date fair value and the vest date fair value of the underlying award. For the three months ended March 31, 2024 and 2023, Pinnacle Financial recognized excess tax benefits of $2.4 million and $277,000, respectively, with respect to the vesting of equity-based awards and the exercise of employee stock options.
