PRINCIPLES OF CONSOLIDATION [Abstract]
PRINCIPLES OF CONSOLIDATION	NOTE 1-PRINCIPLES OF CONSOLIDATION The consolidated financial statements as of June 30, 2012 (unaudited) and December 31, 2011 and for the three and six-month periods ended June 30, 2012 and 2011 (unaudited) include the accounts of TF Financial Corporation (the "Company") and its wholly owned subsidiaries: 3rd Fed Bank (the "Bank"), Penns Trail Development Corporation, and TF Investments Corporation, which was merged into the Company during 2011. The accompanying consolidated balance sheet at December 31, 2011, has been derived from the audited consolidated balance sheet but does not include all of the information and notes required by accounting principles generally accepted in the United States of America ("US GAAP") for complete financial statements. The Company's business is conducted principally through the Bank. All significant intercompany accounts and transactions have been eliminated in consolidation.

Disclosure of accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example, common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. The accounting policy may also address the accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.
