Business and Basis of Presentation [Abstract]
Nature of Operations	Nature of Operations . Capital City Bank Group, Inc. (“CCBG” or the “Company”) provides a full range of banking and banking- related services to individual and corporate clients through its subsidiary, Capital City Bank, with banking offices located in Florida, Georgia, and Alabama. The Company is subject to competition from other financial institutions, is subject to regulation by certain government agencies and undergoes periodic examinations by those regulatory authorities.
Basis of Presentation	Basis of Presentation . The consolidated financial statements in this Quarterly Report on Form 10-Q include the accounts of CCBG and its wholly owned subsidiary, Capital City Bank (“CCB” or the “Bank”). All material inter-company transactions and accounts have been eliminated. Certain previously reported amounts have been reclassified to conform to the current year’s presentation. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. The Consolidated Statement of Financial Condition at December 31, 2023 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and notes required by generally accepted accounting principles for complete financial statements. For further information, refer to the consolidated financial statements and notes thereto included in the Company’s 2023 Form 10-K/A.
Accounting Standards Updates	Accounting Standards Updates Proposed Accounting Standards , ASU 2023-01, “Leases (Topic 842) : Common Control Arrangements.” Accounting Standards Update (“ASU”) 2023-01 requires entities to amortize leasehold improvements associated with common control leases over the useful life to the common control group. ASU 2023-01 also provides certain practical expedients applicable to private companies and not- for-profit organizations. The standard is effective for the Company on January 1, 2024. As the Company does not have any such common control leases, adoption of this standard did not have any immediate impact on its consolidated financial statements and related disclosures. ASU No. 2023-02, “Investments—Equity Method and Joint Ventures (Topic 323) : Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method.” ASU 2023-02 is intended to improve the accounting and disclosures for investments in tax credit structures. ASU 2023-02 allows entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. Previously, this method was only available for qualifying tax equity investments in low-income housing tax credit structures. The standard was effective for the Company on January 1, 2024. As the Company does not have any such investments in tax credit structures that are accounted for using the proportional amortization method, adoption of this standard did not have any immediate impact on its consolidated financial statements or disclosures. ASU No. 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative.” ASU 2023-06 is intended to clarify or improve disclosure and presentation requirements of a variety of topics, which will allow users to more easily compare entities subject to the SEC's existing disclosures with those entities that were not previously subject to the requirements and align the requirements in the FASB accounting standard codification with the SEC's regulations. The Company is currently evaluating the provisions of the amendments and the impact on its future consolidated statements. ASU No. 2023-07, “Improvements to Reportable Segment Disclosures.” ASU 2023-07 requires disclosure of significant segment expenses and other segment items on an interim and annual basis. The standard is effective for fiscal years beginning after December 15, 2023, and for interim periods beginning after December 15, 2024. The Company is currently evaluating the provisions of the amendments and the impact on its future consolidated statements. ASU 2023-09, ”Income Taxes (Topic 740) – Improvements to Income Tax Disclosures.” ASU 2023-09 is intended to increase transparency about income tax information by requiring consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid, disaggregated by jurisdiction. This guidance will be effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the provisions of the amendments and the impact on its future consolidated statements.
