U.S. Nonresident Alien Income Tax Return 2020
Reference Guide
Form 1040-NR applies to individuals who were not U.S. citizens, resident aliens, or lawful
permanent residents for the entire tax year 2020 and had U.S.-source income subject to federal income tax. Nonresident aliens report only income earned from United States sources on this tax return and face restrictions that differ from those imposed on U.S. citizens or resident aliens filing Form 1040.
The Tax Cuts and Jobs Act eliminated personal exemptions for all individual taxpayers beginning in tax year 2018 and continuing through 2025, affecting both residents and nonresident aliens equally. This suspension means no individual can claim personal exemption deductions when calculating taxable income for the 2020 tax season.
Determining Nonresident Alien Status for Tax Year 2020
You qualify as a nonresident alien if you are not a U.S. citizen and you fail both the Green Card
Test and the Substantial Presence Test for 2020. The Green Card Test examines whether you held lawful permanent residence status at any time during the calendar year, while the
Substantial Presence Test calculates whether you were physically present in the United States for a sufficient number of days.
International students, scholars, teachers, and certain other temporary visitors may qualify for exemptions from the Substantial Presence Test under specific visa categories. These individuals must file Form 8843 to document their exempt status and explain why days of U.S.
presence should not count toward the test calculation.
Filing Status Restrictions and Married Taxpayer Elections
Nonresident aliens filing Form 1040-NR must select one of three filing status options: single, married filing separately, or qualifying widow or widower. The Internal Revenue Service prohibits nonresident aliens from using the married filing jointly or head of household filing status when completing this federal income tax return.
An exception exists for nonresident aliens married to U.S. citizens or resident aliens who wish to file jointly. These taxpayers can make an election under Internal Revenue Code sections
6013(g) or 6013(h) to be treated as U.S. residents for the entire tax year.
Making this election requires both spouses to consent and file Form 1040 or Form 1040-SR as residents rather than filing Form 1040-NR as nonresident aliens. This election may result in the forfeiture of tax treaty benefits and in worldwide income being subject to U.S. federal taxes rather than only U.S.-source income.
Income Reporting and Required Documentation
Nonresident aliens must gather all Forms W-2, 1099-NEC, 1099-MISC, 1099-INT, 1099-DIV,
1042-S, and Schedule K-1 showing U.S.-source income for tax year 2020. Effectively connected income includes wages, salaries, business income, and rental income from U.S. real property. In contrast, FDAP income encompasses fixed, determinable, annual, or periodical income, such as interest, dividends, and royalties.
Report effectively connected income on page 1 of Form 1040-NR and complete the applicable numbered schedules, such as Schedule 1 for additional income and adjustments. Independent contractors receiving payments reported on Form 1099-NEC must report this income and may deduct ordinary and necessary business expenses.
Form 1042-S documents income subject to withholding at source and provides information necessary to claim refunds of overwithheld federal income tax. Tax professionals should verify that all documentation matches the amounts reported on the federal income tax return.
Schedule Requirements and Attachment Rules
Schedule OI is mandatory for all taxpayers filing Form 1040-NR, regardless of income type or complexity. This schedule collects information about visa type, tax home, tax treaty benefits claimed, and days of U.S. presence during the tax year.
Schedule NEC is required only when you have U.S.-source income not effectively connected with a U.S. trade or business, such as investment income, dividends, interest income, or royalties subject to withholding. Taxpayers with effectively connected income who do not receive investment income or other FDAP income do not need to complete Schedule NEC.
Deductions, Exemptions, and Credit Limitations
Individual nonresident aliens cannot claim personal exemptions on their 2020 federal income tax return because the Tax Cuts and Jobs Act suspended these exemptions for all individual
taxpayers through 2025. Most nonresident aliens cannot claim the standard deduction and must itemize deductions on Schedule A if they wish to reduce taxable income.
An exception applies to students and business apprentices from India who qualify under Article
21(2) of the United States–India income tax treaty. These individuals may claim both a limited standard deduction and an above-the-line charitable deduction of up to $300 for qualified cash contributions.
Nonresident aliens generally cannot claim the Earned Income Tax Credit, Additional Child Tax
Credit, or education credits. Residents of Canada and Mexico can claim the Child Tax Credit and credit for other dependents on the same terms as U.S. citizens.
Residents of South Korea and eligible students or business apprentices from India may claim these credits under more limited terms described in Publication 519. The foreign tax credit remains available to nonresident aliens who paid income taxes to foreign countries on income also subject to U.S. federal taxes.
Economic Impact Payments and Unemployment
Exclusion
Economic Impact Payments were not available to nonresident aliens for the 2020 tax year, and the Recovery Rebate Credit could not be claimed on Form 1040-NR. According to the Form
1040-NR instructions, line 30 is designated for future use, and individuals filing this return are not permitted to claim the recovery rebate credit that applied to U.S. citizens and resident aliens.
Under the American Rescue Plan Act, an exclusion for unemployment compensation was permitted in 2020 for certain nonresident aliens filing Form 1040-NR. Eligible taxpayers were allowed to exclude up to $10,200 of unemployment compensation from income, provided their modified adjusted gross income fell below the applicable threshold limits.
Tax Withholding, Estimated Payments, and Filing
Procedures
Enter all federal income tax withheld from Forms W-2, 1099, 1042-S, and other documents on the appropriate lines of Form 1040-NR. Nonresident aliens who receive FDAP income typically have tax withheld at a flat 30% rate unless a tax treaty reduces the withholding rate.
Estimated tax payments made during 2020 and any overpayment applied from the prior year tax return must be reported to calculate the total payments available to offset tax liability or generate a tax refund. Publication 519 provides detailed guidance on withholding rules and estimated tax requirements for nonresident aliens throughout the tax season.
The tax filing deadline for nonresident aliens with wages subject to withholding is April 15 of the year following the tax year. Nonresident aliens not subject to wage withholding must file by the fifteenth day of the sixth month after the tax year ends.
