Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective income tax rate was 14.7% for the third quarter of fiscal 2021 and 26.2% for the third quarter of fiscal 2020. The effective income tax rate was 43.9% for the nine months ended October 31, 2020 compared to 25.7% for the nine months ended November 2, 2019. The decrease in the third quarter, and increase in the year to date, effective income tax rates of fiscal 2021 are primarily due to the jurisdictional mix of profits and losses and the better than anticipated third quarter results. TJX had net unrecognized tax benefits of $267.1 million as of October 31, 2020, $254.8 million as of February 1, 2020 and $245.8 million as of November 2, 2019. TJX is subject to U.S. federal income tax as well as income tax in multiple state, local and foreign jurisdictions. In the U.S. and India, fiscal years through 2010 are no longer subject to examination. In all other jurisdictions, fiscal years through 2011 are no longer subject to examination. TJX’s accounting policy classifies interest and penalties related to income tax matters as part of income tax expense. The total accrued amount on the Consolidated Balance Sheets for interest and penalties was $34.2 million as of October 31, 2020, $27.9 million as of February 1, 2020 and $29.3 million as of November 2, 2019. Based on the outcome of tax examinations or judicial or administrative proceedings, or as a result of the expiration of statutes of limitations in specific jurisdictions, it is reasonably possible that unrecognized tax benefits for certain tax positions taken on previously filed tax returns may change materially from those presented in the Consolidated Financial Statements. During the next 12 months, it is reasonably possible that tax examinations of prior years’ tax returns or judicial or administrative proceedings that reflect such positions taken by TJX may be finalized. As a result, the total net amount of unrecognized tax benefits may decrease, which would reduce the provision for taxes on earnings, by a range of zero to $38 million.
