Taxation in the US: Internal Revenue Service (IRS) tax forms (Part Two)
The Form 1040NR, U.S. Nonresident Alien Income Tax Return, and its shorter version Form 1040NR-EZ, U.S. Income Tax Return for Certain Nonresident Aliens With No Dependents, are used by nonresident aliens who have U.S. source income and therefore have to file a U.S. tax return. Joint returns are not permitted, so that husband and wife must each file a separate return. The Form 1040NR-EZ can be used under conditions similar to those for the 1040EZ form.
The Form 1040X, Amended U.S. Individual Tax Return, is used to make corrections to Form 1040, Form 1040A, and Form 1040EZ tax returns that have been previously filed. Generally for a tax refund, this form must be filed within 3 years after the date that the original version was filed, or within 2 years after the date that the tax was paid, whichever is later. Forms 1040X are processed manually and therefore take longer than regular returns. For years prior to 2010, Form 1040X had three columns: for the amounts from the original version, for the net increase or decrease for each line being changed, and for the corrected amounts. For 2010, the form was condensed with a single column for the corrected amounts. Due to confusion amongst taxpayers on how to complete the single-column form, the IRS revised the Form 1040X again for 2011 by returning to the original three-column format.
Self-employed individuals and others who do not have enough income taxes withheld, might need to file Form 1040-ES, Estimated Tax for Individuals, each quarter to make estimated installments of annual tax liability (pay-as-you-go tax).
