Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective income tax rate was (132.8)% for the second quarter of fiscal 2021 and 25.7% for the second quarter of fiscal 2020. The effective income tax rate was 23.2% for the six months ended August 1, 2020 compared to 25.5% for the six months ended August 3, 2019. The second quarter’s negative effective income tax rate is primarily due to the reversal of income tax benefit recorded in the first quarter of fiscal 2021 related to the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) enacted on March 27, 2020. The CARES Act provides for net operating losses incurred in fiscal 2021 to be carried back to earlier tax years with higher tax rates than the current year. The projected losses subject to carry back to earlier years decreased in the second quarter of fiscal 2021, resulting in a reduction of the year to date income tax benefit and a second quarter negative effective income tax rate. TJX had net unrecognized tax benefits of $262.2 million as of August 1, 2020, $254.8 million as of February 1, 2020 and $241.6 million as of August 3, 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 $32.0 million as of August 1, 2020, $27.9 million as of February 1, 2020 and $27.3 million as of August 3, 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 $36.0 million.
