Accounting Policies [Abstract]  
Basis of Presentation Basis of Presentation:  The accompanying unaudited consolidated financial statements of Timberland Bancorp, Inc. and its wholly-owned subsidiary, Timberland Bank (the "Bank") (collectively, "the Company") were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with instructions for Form 10-Q and, therefore, do not include all disclosures necessary for a complete presentation of consolidated financial condition, results of operations, and cash flows in conformity with GAAP. However, all adjustments which are, in the opinion of management, necessary for a fair presentation of the interim consolidated financial statements have been included.  All such adjustments are of a normal recurring nature. The unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2025 (“2025 Form 10-K”).  The unaudited consolidated results of operations for the nine months ended June 30, 2026 are not necessarily indicative of the results that may be expected for the entire fiscal year ending September 30, 2026.
Principles of Consolidation Principles of Consolidation:  The unaudited consolidated financial statements include the accounts of the Company, its wholly-owned subsidiary, the Bank, and the Bank's wholly owned subsidiary, Timberland Service Corp. All significant inter-company transactions and balances have been eliminated in consolidation.
Operating Segment Operating Segment:  The Company's revenue is primarily derived from the business of banking. Management has assigned certain responsibilities by business-line and evaluates financial performance on a Company-wide basis. The Company's financial performance is monitored on a consolidated basis by the Company's Chief Executive Officer, President and Chief Financial Officer, which are considered the Company's chief operating decision makers ("CODMs") for financial oversight. The primary measure of performance is consolidated net income. Financial performance is reviewed monthly by the CODMs. The presentation of financial performance is consistent with amounts and financial statement line items shown in the Company's consolidated balance sheets and consolidated statements of income. All of the Company's operations are considered by management to be aggregated in one reportable operating segment.
Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities, as of the date of the consolidated balance sheets, and the reported amounts of income and expenses during the reporting period.  Actual results could differ from those estimates.
Reclassification Certain prior period amounts have been reclassified to conform to the June 30, 2026 presentation with no change to previously reported net income or total shareholders’ equity.
Revenue from Contract with Customer
ASU 2014-09 Revenue from Contracts with Customers ("ASC 606") applies to all contracts with customers to provide goods or services in the ordinary course of business, except for contracts that are specifically excluded from its scope. The majority of the Company's revenues are composed of interest income, deferred loan fee accretion, premium/discount accretion, gains on sales of loans and investments, BOLI net earnings, servicing income on loans sold and other loan fee income, which are not within the scope of ASC 606. Revenue reported as service charges on deposits, ATM and debit card interchange transaction fees, non-deposit investment fees and escrow fees are within the scope of ASC 606. All of the Company's revenue from contracts with customers within the scope of ASC 606 is recognized in non-interest income with the exception of gains on sales of OREO and gains on sales/disposition of premises and equipment, which are included in non-interest expense. For the three months ended June 30, 2026, the Company recognized $956,000 in service charges on deposits, $1.19 million in ATM and debit card interchange transaction fees, $42,000 in escrow fees, and $17,000 in fee income from non-deposit investment sales included in "Other, net" in non-interest income on the consolidated statement of income, all considered within the scope of ASC 606. For the nine months ended June 30, 2026, the Company recognized $2.88 million in service charges on deposits, $3.52 million in ATM and debit card interchange transaction fees, $94,000 in escrow fees, and $53,000 in fee income from non-
deposit investment sales included in "Other, net" in non-interest income on the consolidated statement of income, all considered within the scope of ASC 606. For the three months ended June 30, 2025, the Company recognized $966,000 in service charges on deposits, $1.26 million in ATM and debit card interchange transaction fees, $32,000 in escrow fees, and $9,000 in fee income from non-deposit investment sales. For the nine months ended June 30, 2025, the Company recognized $2.92 million in service charges on deposits, $3.71 million in ATM and debit card interchange transaction fees, $66,000 in escrow fees, and $12,000 in fee income from non-deposit investment sales.

If a contract is determined to be within the scope of ASC 606, the Company recognizes revenue when it satisfies its performance obligation. Descriptions of the Company's revenue-generating activities that are within the scope of ASC 606 are as follows:

Service Charges on Deposits: The Company earns fees from its deposit customers from a variety of deposit products and services. Non-transaction based fees such as account maintenance fees and monthly statement fees are considered to be provided to the customer under a day-to-day contract with ongoing renewals. Revenue for these non-transaction fees are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Transaction-based fees such as non-sufficient fund charges, stop payment charges and wire fees are recognized at the time the transaction is executed, as the contract duration does not extend beyond the service performed.
ATM and Debit Card Interchange Transaction Fees: The Company earns fees from cardholder transactions conducted through third-party payment network providers which consist of interchange fees earned from the payment networks as a debit card issuer. These fees are recognized when the transaction occurs, but may settle on a daily or monthly basis.
Escrow Fees: The Company earns fees from real estate escrow contracts with customers. The Company receives and disburses money and/or property according to the customer's contract. Fees are recognized when the escrow contract closes.
Fee Income from Non-deposit Investment Sales: The Company earns fees from contracts with customers for investment activities. Revenues are generally recognized monthly and are generally based on a percentage of the customer's assets under management or based on investment solutions that are implemented for the customer.
