Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Significant Accounting Policies Basis of Presentation Our condensed consolidated financial statements include the accounts of Toll Brothers, Inc. (the “Company,” “we,” “us,” or “our”), a Delaware corporation, and its majority owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. Investments in 50% or less owned partnerships and affiliates are accounted for using the equity method unless it is determined that we have effective control of the entity, in which case we would consolidate the entity. Our unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. The October 31, 2023 balance sheet amounts and disclosures have been derived from our October 31, 2023 audited financial statements. Since the condensed consolidated financial statements do not include all the information and footnotes required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements, they should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended October 31, 2023 (“2023 Form 10-K”). In the opinion of management, the unaudited condensed consolidated financial statements include all recurring adjustments necessary to present fairly our financial position as of April 30, 2024; the results of our operations and changes in equity for the three-month and six-month periods ended April 30, 2024 and 2023; and our cash flows for the six-month periods ended April 30, 2024 and 2023. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year. Use of Estimates The preparation of financial statements in accordance with GAAP requires estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Estimates and assumptions may prove to be incorrect for a variety of reasons, whether as a result of the risks and uncertainties our business is subject to or for other reasons. In times of economic disruption when uncertainty regarding future economic conditions is heightened, our estimates and assumptions are subject to greater variability. Actual results could differ from the estimates and assumptions we make and such differences may be material. Revenue Recognition Home sales revenues: Revenues and cost of revenues from home sales are recognized at the time each home is delivered and title and possession are transferred to the buyer. For the majority of our home closings, our performance obligation to deliver a home is satisfied in less than one year from the date a binding sale agreement is signed. In certain states where we build, we are not able to complete certain outdoor features prior to the closing of the home. To the extent these separate performance obligations are not complete upon the home closing, we defer a portion of the home sales revenues related to these obligations and subsequently recognize the revenue upon completion of such obligations. As of April 30, 2024, the home sales revenues and related costs we deferred related to these obligations were immaterial. Our contract liabilities, consisting of deposits received from customers for sold but undelivered homes, totaled $542.9 million and $540.7 million at April 30, 2024 and October 31, 2023, respectively. Of the outstanding customer deposits held as of October 31, 2023, we recognized $153.1 million and $290.3 million in home sales revenues during the three months and six months ended April 30, 2024, respectively. Of the outstanding customer deposits held as of October 31, 2022, we recognized $152.2 million and $275.1 million in home sales revenues during the three months and six months ended April 30, 2023, respectively. Land sales and other revenues: Our revenues from land sales and other generally consist of: (1) land sales to joint ventures in which we retain an interest; (2) lot sales to third-party builders within our master-planned communities; (3) bulk lot sales to third parties of land we have decided no longer meets our development criteria; (4) sales of land parcels to third parties (typically because there is a superior economic use of the property); and (5) sales of commercial and retail properties generally located at our high-rise urban luxury condominium projects. In general, our performance obligation for each of these land sales is fulfilled upon the delivery of the land, which generally coincides with the receipt of cash consideration from the counterparty. For land sale transactions that contain repurchase options, revenues and related costs are not recognized until the repurchase option expires. In addition, when we sell land to a joint venture in which we retain an interest, we do not recognize revenue or gains on the sale to the extent of our retained interest in such joint venture. In February 2024, we sold a parcel of land to a commercial developer for net cash proceeds of $180.7 million, which resulted in a pre-tax gain of $175.2 million during the three and six months ended April 30, 2024. Forfeited Customer Deposits: Forfeited customer deposits are recognized in “Home sales revenues” in our Condensed Consolidated Statements of Operations and Comprehensive Income in the period in which we determine that the customer will not complete the purchase of the home and we have the right to retain the deposit. Sales Incentives: In order to promote sales of our homes, we may offer our home buyers sales incentives. These incentives vary by type of incentive and by amount on a community-by-community and home-by-home basis. Incentives are reflected as a reduction in home sales revenues. Incentives are recognized at the time the home is delivered to the home buyer and we receive the sales proceeds. Recent Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”). ASU 2023-07 requires disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items to reconcile to segment profit or loss, and the title and position of the entity’s CODM. The amendments in this update also expand the interim segment disclosure requirements. ASU 2023-07 will be effective for our fiscal year ending October 31, 2025 and for interim periods starting in our first quarter of fiscal 2026. Early adoption is permitted and the amendments in this update are required to be applied on a retrospective basis. We are currently reviewing the impact that the adoption of ASU 2023-07 may have on our consolidated financial statements and disclosures. In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which requires expanded disclosure of our income tax rate reconciliation and income taxes paid. ASU 2023-09 will be effective for our fiscal year ending October 31, 2026 and may be applied either retrospectively or prospectively. We are currently evaluating ASU 2023-09 and do not expect it to have a material effect on our consolidated financial statements and disclosures. In March 2024, the SEC issued final rules on the enhancement and standardization of climate-related disclosures. The rules require disclosure of material climate-related risks; activities to mitigate or adapt to such risks; governance and management of such risks; and material greenhouse gas (GHG) emissions from operations owned or controlled (Scope 1) and/or indirect emissions from purchased energy consumed in operations (Scope 2). Additionally, the rules require disclosures in the notes to the financial statements of the effects of severe weather events and other natural conditions, subject to certain materiality thresholds. Annual disclosure requirements will become effective for us, in part, for our fiscal year ending October 31, 2025, with certain requirements of the rule subject to later compliance dates. On March 15, 2024, a federal appellate court imposed a temporary stay pending judicial review of these new rules and on April 4, 2024, the SEC subsequently voluntarily stayed implementation pending completion of the judicial review. We are currently evaluating the impact of this final rule on our disclosures. Reclassification Certain prior period amounts have been reclassified to conform to the fiscal 2024 presentation.
