Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Significant Accounting Policies Basis of Presentation The accompanying 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. The accompanying 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, 2016 balance sheet amounts and disclosures included herein have been derived from our October 31, 2016 audited financial statements. Since the accompanying 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, we suggest that they be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended October 31, 2016 (“2016 Form 10-K”). In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, which are of a normal recurring nature, necessary to present fairly our financial position as of April 30, 2017; the results of our operations for the six-month and three-month periods ended April 30, 2017 and 2016; and our cash flows for the six-month periods ended April 30, 2017 and 2016. The results of operations for such interim periods are not necessarily indicative of the results to be expected for the full year. Acquisition In November 2016, we acquired substantially all of the assets and operations of Coleman Real Estate Holdings, LLC (“Coleman”) for $85.2 million in cash. The assets acquired were primarily inventory, including approximately 1,750 home sites owned or controlled through land purchase agreements. As part of the acquisition, we assumed contracts to deliver 128 homes with an aggregate value of $38.8 million. The average price of the undelivered homes at the date of acquisition was approximately $303,000. Our selling community count increased by 15 communities at the acquisition date. The acquisition of Coleman’s assets and operations was not material to our results of operations or financial condition. Recent Accounting Pronouncements In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-05, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customers’ Accounting for Fees Paid in a Cloud Computing Arrangement” (“ASU 2015-05”). ASU 2015-05 provides guidance for a customer to determine whether a cloud computing arrangement contains a software license or should be accounted for as a service contract. We adopted ASU 2015-05 on November 1, 2016, and we elected to adopt the standard prospectively. The adoption did not have a material effect on our consolidated financial statements or disclosures. In February 2015, the FASB issued ASU No. 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis” (“ASU 2015-02”), which eliminates the deferral granted to investment companies from applying the variable interest entities (“VIEs”) guidance and makes targeted amendments to the current consolidation guidance. The new guidance applies to all entities involved with limited partnerships or similar entities and requires re-evaluation of these entities under the revised guidance which may change previous consolidation conclusions. We adopted ASU 2015-02 on November 1, 2016, and the adoption did not have a material effect on our consolidated financial statements or disclosures. In March 2017, the FASB issued ASU No. 2017-07, “Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (“ASU 2017-07”). ASU 2017-07 requires an employer to report the service cost component of pension and other postretirement benefit costs in the same line item as other compensation costs arising from services rendered by the pertinent employees while the other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations. ASU 2017-07 is effective for our fiscal year beginning November 1, 2018. Early adoption is permitted. We are currently evaluating the impact that the adoption of ASU 2017-07 may have on our consolidated financial statements and disclosures. In February 2017, the FASB issued ASU No. 2017-05, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets” (“ASU 2017-05”). ASU 2017-05 is meant to clarify the scope of the original guidance within Subtopic 610-20 that was issued in connection with ASU 2014-09, as defined below, which provides guidance for recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. ASU 2017-05 also added guidance for partial sales of nonfinancial assets. ASU 2017-05 is effective for our fiscal year beginning November 1, 2018 and we are required to adopt ASU 2017-05 concurrent with the adoption of ASU 2014-09. We are currently evaluating the impact that the adoption of ASU 2017-05 may have on our consolidated financial statements and disclosures. In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”), which provides guidance for revenue recognition. ASU 2014-09 affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets. ASU 2014-09 supersedes the revenue recognition requirements in Accounting Standards Codification (“ASC”) Topic 605, “Revenue Recognition,” and most industry-specific guidance. ASU 2014-09 also supersedes some cost guidance included in ASC Subtopic 605-35, “Revenue Recognition—Construction-Type and Production-Type Contracts.” The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which a company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under the current guidance. These judgments and estimates include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price, and allocating the transaction price to each separate performance obligation. In August 2015, the FASB issued ASU 2015-14 “Revenue from Contracts with Customers” (“ASU 2015-14”), which delays the effective date of ASU 2014-09 by one year. ASU 2014-09, as amended by ASU 2015-14, is effective for our fiscal year beginning November 1, 2018, and, at that time, we expect to adopt the new standard under the modified retrospective approach. We do not believe the adoption of ASU 2014-09 will have a material impact on the amount or timing of our home building revenues. We are continuing to evaluate the impact the adoption of ASU 2014-09 may have on other aspects of our business and on our consolidated financial statements and disclosures. In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business” (“ASU 2017-01”), which provides a more robust framework for determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01 is effective for our fiscal year beginning November 1, 2018. We are currently evaluating the impact that the adoption of ASU 2017-01 may have on our consolidated financial statements and disclosures. In March 2016, the FASB issued ASU No. 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). ASU 2016-09 simplifies several aspects related to the accounting for share-based payment transactions, including the accounting for income taxes and forfeitures, statutory tax withholding requirements and classification on the statement of cash flows. ASU 2016-09 is effective for our fiscal year beginning November 1, 2017. We are currently evaluating the impact that the adoption of ASU 2016-09 may have on our consolidated financial statements and disclosures. In February 2016, the FASB issued ASU No. 2016-02, “Leases” (“ASU 2016-02”), which requires an entity to recognize assets and liabilities on the balance sheet for the rights and obligations created by leased assets and provide additional disclosures. ASU 2016-02 is effective for our fiscal year beginning November 1, 2019, and, at that time, we will adopt the new standard using a modified retrospective approach. We are currently evaluating the impact that the adoption of ASU 2016-02 may have on our consolidated financial statements and disclosures.

We are continuing to evaluate the impact the adoption of ASU 2014-09 may have on other aspects of our business and on our consolidated financial statements and disclosures.
