Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Consolidated Financial Statements and Notes thereto have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. These Consolidated Financial Statements and Notes thereto are unaudited and, in the opinion of management, reflect all normal recurring adjustments, accruals and deferrals among periods required to match costs properly with the related revenue or activity, considered necessary by The TJX Companies, Inc. (together with its subsidiaries, “TJX”) for a fair statement of its Consolidated Financial Statements for the periods reported, all in conformity with GAAP consistently applied. Investments for which the Company exercises significant influence but does not have control are accounted for under the equity method. The Consolidated Financial Statements and Notes thereto should be read in conjunction with the audited Consolidated Financial Statements, including the related notes, contained in TJX’s Annual Report on Form 10-K for the fiscal year ended January 30, 2021 (“fiscal 2021”). These interim results are not necessarily indicative of results for the full fiscal year. TJX’s business, in common with the businesses of retailers generally, is subject to seasonal influences, with higher levels of sales and income generally realized in the second half of the year. The January 30, 2021 balance sheet data was derived from audited Consolidated Financial Statements and does not include all disclosures required by GAAP.
Fiscal Year	Fiscal Year TJX’s fiscal year ends on the Saturday nearest to the last day of January of each year. The current fiscal year ends January 29, 2022 (“fiscal 2022”) and is a 52-week fiscal year. Fiscal 2021 was also a 52-week fiscal year.
Use of Estimates	Use of Estimates The preparation of financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. TJX considers its accounting policies relating to leases, inventory valuation, impairment of long-lived assets, reserves for uncertain tax positions and loss contingencies to be the most significant accounting policies that involve management estimates and judgments. The Company considered COVID-19 related impacts to its estimates, as appropriate, within its consolidated financial statements and there may be changes to those estimates in future periods. The Company believes that its accounting estimates are appropriate after giving consideration to the ongoing uncertainties surrounding the severity and duration of the COVID-19 pandemic and the associated containment and remediation efforts. Actual amounts could differ from these estimates, and such differences could be material.
Reclassifications	Reclassifications Certain reclassifications have been made to prior year financial information to conform to the current year’s presentation.
Future Adoption of New Accounting Standards	Future Adoption of New Accounting Standards From time to time, the Financial Accounting Standards Board (“FASB”) or other standard setting bodies issue new accounting pronouncements. Updates to the FASB Accounting Standards Codification are communicated through issuance of an Accounting Standards Update (“ASU”). Unless otherwise discussed, the Company has reviewed the guidance and have determined that they will not apply or are not expected to be material to its Consolidated Financial Statements upon adoption and therefore are not disclosed.
