ACCOUNTING POLICIES (Policies)	3 Months Ended

ACCOUNTING POLICIES [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Primis and its subsidiaries Primis Bank and EVB Statutory Trust I (the “Trust”). Significant inter-company accounts and transactions have been eliminated in consolidation. Primis consolidates subsidiaries in which it holds, directly or indirectly, more than 50 percent of the voting rights or where it exercises control. Entities where Primis holds 20 to 50 percent of the voting rights, or has the ability to exercise significant influence, or both, are accounted for under the equity method. Primis owns the Trust which is an unconsolidated subsidiary and the junior subordinated debt owed to the Trust is reported as a liability of Primis.
Discontinued Operation	Discontinued Operation Primis Bank had an interest in one mortgage company, Southern Trust Mortgage, LLC (“STM”). Prior to December 31, 2021, Primis Bank owned 43.28% and 100% of STM’s common and preferred stock, respectively, and STM was considered an unconsolidated affiliate of the Company. On September 23, 2021, Primis Bank entered into an agreement with STM, whereby STM agreed to purchase all of the Bank's common membership interests and a portion of the Bank's preferred interests in STM for a combination of $1.6 million in cash and a promissory note for $8.5 million. The transaction closed on December 31, 2021. Upon closing, STM continued to be a borrower of the Bank, but the Bank is no longer a minority owner of STM and STM is no longer considered an affiliate of the Company. The Company still holds 100% of STM’s preferred stock at March 31, 2022 but no longer has a position on STM’s board of directors and STM no longer represents a reportable operating segment of the Company.
Operating Segments	Operating Segments Operating segments are defined as components of a company about which separate financial information is available that is evaluated regularly by the chief financial officer and chief accounting officer in deciding how to allocate resources and in assessing performance. Discrete financial information is not available other than on a company-wide basis. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment.
Basis of Presentation	Basis of Presentation The unaudited consolidated financial statements and notes thereto have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and instructions for Form 10-Q and follow general practice within the banking industry. Accordingly, the unaudited consolidated financial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. However, in the opinion of management, all adjustments (consisting only of normal recurring accruals) necessary for a fair presentation of the results of the interim periods presented have been made. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year. For further information, refer to the consolidated financial statements and footnotes thereto included in Primis’ Annual Report on Form 10-K for the year ended December 31, 2021.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. Estimates that are particularly susceptible to change in the near term include: the determination of the allowance for credit losses, the fair value of investment securities, credit impairment of investment securities, the valuation of goodwill and deferred tax assets.
Reclassifications	Reclassifications In certain instances, amounts reported in prior years’ consolidated financial statements have been reclassified to conform to the current financial statement presentation. Such reclassifications had no effect on previously reported cash flows, stockholders’ equity or net income.
Recent Accounting Pronouncements	Recent Accounting Pronouncements New Accounting Standards Not Yet Adopted: In March 2022, FASB issued ASU 2022-02, Troubled Debt Restructurings and Vintage Disclosures. This ASU eliminates the accounting guidance on troubled debt restructurings (TDRs) for creditors in ASC 310-402 and amends the guidance on “vintage disclosures” to require disclosure of current-period gross write-offs by year of origination. The ASU also updates the requirements related to accounting for credit losses under Accounting Standards Codification (“ASC”) 326 and adds enhanced disclosures for creditors with respect to loan refinancing and restructurings for borrowers experiencing financial difficulty. ASU 2022-02 is effective for annual periods beginning after December 15, 2022, including interim periods within those annual periods. Early adoption is permitted. Primis is currently in the process of evaluating the impact of adopting the new guidance on its consolidated financial statements and disclosures.
