Basis of Presentation and Significant Accounting Policies [Text Block]	1. The unaudited consolidated financial statements include the accounts of MBT Financial Corp. (the “Company”) and its subsidiary, Monroe Bank & Trust (the “Bank”). The Bank includes the accounts of its wholly owned subsidiary, MB&T Financial Services, Inc. The Bank operates fourteen six one On October 9, 2018, 0.275 third third not The accounting and reporting policies of the Bank conform to practice within the banking industry and are in accordance with accounting principles generally accepted in the United States. Preparation of financial statements in conformity with generally accepted accounting principles requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes in the near term are the determination of the allowance for loan losses and the fair value of investment securities. The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with the instructions to Form 10 not The significant accounting policies are as follows: PRINCIPLES OF CONSOLIDATION The consolidated financial statements include the accounts of the Company and its subsidiary. All material intercompany transactions and balances have been eliminated. COMPREHENSIVE INCOME Accounting principles generally require that revenue, expenses, gains, and losses be included in net income. Certain changes in assets and liabilities, however, such as unrealized gains and losses on securities available for sale and amounts recognized related to postretirement benefit plans (gains and losses, prior service costs, and transition assets or obligations), are reported as a direct adjustment to the equity section of the balance sheet. Such items, along with net income, are components of comprehensive income. BUSINESS SEGMENTS While the Company's chief decision makers monitor the revenue streams of various products and services, operations are managed and financial performance is evaluated on a company wide basis. Accordingly, all of the Company’s operations are considered by management to be aggregated in one FAIR VALUE The Company measures or monitors many of its assets and liabilities on a fair value basis. Fair value is used on a recurring basis for assets and liabilities that are elected to be accounted for under The Fair Value Option as well as for certain assets and liabilities in which fair value is the primary basis of accounting. Examples of these include derivative instruments and available for sale securities. Additionally, fair value is used on a non-recurring basis to evaluate assets or liabilities for impairment or for disclosure purposes. Examples of these non-recurring uses of fair value include certain loans held for sale accounted for on a lower of cost or market basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, the Company uses various valuation techniques and assumptions when estimating fair value. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at and/or marked to fair value, the Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability. When possible, the Company looks to active and observable markets to price identical assets or liabilities. When identical assets and liabilities are not not ACCOUNTING PRONOUNCEMENTS The Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2014 09 2014 09 606 2014 09 2014 09 December 15, 2017 ( December 31, 2018 not 2014 09 January 1, 2018 not In June 2016, No. 2016 13, December 31, 2020. first December 15, 2018, In March 2017, No. 2017 08, 310 20 not December 15, 2018, not In January 2016, No. 2016 01, 825 10 2016 01 December 15, 2017. 2016 01 January 1, 2018 not

The provision for loan losses increases the allowance for loan losses, a valuation account which appears on the consolidated balance sheets. As the specific customer and amount of a loan loss is confirmed by gathering additional information, taking collateral in full or partial settlement of the loan, bankruptcy of the borrower, etc., the loan is charged off, reducing the allowance for loan losses. If, subsequent to a charge off, the Bank is able to collect additional amounts from the customer or sell collateral worth more than earlier estimated, a recovery is recorded. To serve as a basis for making this provision, the Bank maintains an extensive credit risk monitoring process that considers several factors including: current economic conditions affecting the Bank’s customers, the payment performance of individual loans and pools of homogeneous loans, portfolio seasoning, changes in collateral values, and detailed reviews of specific loan relationships. The Company utilizes an internal loan grading system to assign a risk grade to all commercial loans, all renegotiated loans, and each commercial credit relationship.

Fair value is used on a recurring basis for Available for Sale Securities. Additionally, fair value is used on a non-recurring basis to evaluate assets or liabilities for impairment or for disclosure purposes. Examples of these non-recurring uses of fair value include certain loans held for sale accounted for on a lower of cost or market basis. Depending on the nature of the asset or liability, the Company uses various valuation techniques and assumptions when estimating fair value.

Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	PRINCIPLES OF CONSOLIDATION The consolidated financial statements include the accounts of the Company and its subsidiary. All material intercompany transactions and balances have been eliminated.
Comprehensive Income, Policy [Policy Text Block]	COMPREHENSIVE INCOME Accounting principles generally require that revenue, expenses, gains, and losses be included in net income. Certain changes in assets and liabilities, however, such as unrealized gains and losses on securities available for sale and amounts recognized related to postretirement benefit plans (gains and losses, prior service costs, and transition assets or obligations), are reported as a direct adjustment to the equity section of the balance sheet. Such items, along with net income, are components of comprehensive income.
Segment Reporting, Policy [Policy Text Block]	BUSINESS SEGMENTS While the Company's chief decision makers monitor the revenue streams of various products and services, operations are managed and financial performance is evaluated on a company wide basis. Accordingly, all of the Company’s operations are considered by management to be aggregated in one
Fair Value Measurement, Policy [Policy Text Block]	FAIR VALUE The Company measures or monitors many of its assets and liabilities on a fair value basis. Fair value is used on a recurring basis for assets and liabilities that are elected to be accounted for under The Fair Value Option as well as for certain assets and liabilities in which fair value is the primary basis of accounting. Examples of these include derivative instruments and available for sale securities. Additionally, fair value is used on a non-recurring basis to evaluate assets or liabilities for impairment or for disclosure purposes. Examples of these non-recurring uses of fair value include certain loans held for sale accounted for on a lower of cost or market basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, the Company uses various valuation techniques and assumptions when estimating fair value. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at and/or marked to fair value, the Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability. When possible, the Company looks to active and observable markets to price identical assets or liabilities. When identical assets and liabilities are not not
