Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective income tax rate was 26.0% for the first quarter of fiscal 2022 and 33.9% for the first quarter of fiscal 2021. The decrease in the effective income tax rate was primarily a result of the ability to carry back the anticipated loss from the first quarter of fiscal 2021 to earlier tax years with higher tax rates due to a benefit provided by the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) enacted on March 27, 2020. TJX had net unrecognized tax benefits of $278 million as of May 1, 2021, $272 million as of January 30, 2021 and $256 million as of May 2, 2020. 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 $38 million as of May 1, 2021, $36 million as of January 30, 2021 and $30 million as of May 2, 2020. 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 $42 million.
