Accounting Policies [Abstract]
Basis of Presentation	Note A – Basis of Presentation The accompanying unaudited consolidated financial statements of Heritage NOLA Bancorp, Inc. and Subsidiary (the “Company”) were prepared in accordance with instructions for Form 10‑Q and Regulation S-X and do not include information or footnotes necessary for a complete presentation of financial condition, results of operations, comprehensive income, changes in equity and cash flows in conformity with accounting principles generally accepted in the United States of America. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the financial statements have been included. The results of operations for the three and nine month periods ended September 30, 2019 are not necessarily indicative of the results which may be expected for the entire year. These statements should be read in conjunction with the Financial Statements and notes thereto for the year ended December 31, 2018 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 as filed with the Securities and Exchange Commission (“SEC”). Reference is made to the accounting policies of the Company described in the Notes to the Financial Statements contained in the Annual Report. In preparing the financial statements, the Company is required to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. The financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the Company’s financial condition, results of operations, comprehensive income, changes in shareholders’ equity and cash flows for the interim periods presented. These adjustments are of a normal recurring nature and include appropriate estimated provisions. The consolidated financial statements include Heritage NOLA Bancorp, Inc. and its wholly-owned subsidiary, Heritage Bank of St. Tammany (the “Bank”), together referred to as the Company. Intercompany transactions and balances have been eliminated in consolidation. Certain reclassifications have been made to the 2018 financial information in order to conform to the 2019 financial statement presentation. Such reclassifications had no effect on previously reported net income.
