What IRS Form 1040-NR (2020) Is For
IRS Form 1040-NR serves as the federal return for individuals who did not meet the substantial presence test or the green card test during the 2020 tax year. The Internal Revenue Service uses the form to assess taxation on gross income linked to a U.S. trade or business or other U.S. source income. The return also applies when a nonresident alien beneficiary or a nonresident alien landlord reports effectively connected income under the Treasury regulations.
Individuals from a foreign country report dividends, gains, and compensation from U.S. sources. They also report original issue discount when rules require disclosure. Their entries follow Internal Revenue Service guidance for compliance.
When You’d Use IRS Form 1040-NR (2020)
Individuals file Form 1040-NR when they earned wages, compensation, or business income from a U.S. trade or business during the 2020 tax year. They also file when they received dividends, capital gains, or FDAP income from U.S.-source income. The filing requirement applies to individuals from a foreign country who performed personal services in the United States.
A person uses the form when income qualifies as effectively connected income or when income tax treaties require reporting of such income. A foreign taxpayer who paid insurance premiums or mortgage interest related to U.S. activity also meets filing requirements. Nonresidents must follow Internal Revenue Service rules for filing status selection.
Key Rules or Details for 2020
Form 1040-NR limits filing status choices to single, married filing separately, or qualifying widow(er) for income tax purposes. The Internal Revenue Service applies tax rules to nonresident taxpayers who cannot claim certain deductions or credits that apply to U.S. citizens or residents. Individuals report gross income from a U.S. trade or business, FDAP income, or gains that the Treasury regulations treat as effectively connected income.
A taxpayer may apply an income tax treaty that offers a reduced rate or an exempt category for such income. Some treaties apply to dividends, capital gains, wages, or compensation earned in the United States. Certain taxpayers claim insurance premiums, mortgage interest, or a social security equivalent when rules permit.
Step-by-Step (High Level)
Step 1: A taxpayer verifies whether the substantial presence test or the green card test was not met for the tax year. The taxpayer confirms that foreign status continued during the tax year and that the trade or business activities generated effectively connected income. The taxpayer identifies FDAP income or capital gains associated with U.S.-source activities.
Step 2: The taxpayer collects Forms W-2, 1042-S, and 1099 that relate to wages, gains, or dividends. The taxpayer assembles records for distributable net income, business income, real property interests, or insurance premiums. The taxpayer gathers documents related to any income tax treaty that affects the filing requirements.
Step 3: The taxpayer enters personal information, foreign country residence, and filing status. The taxpayer reports effectively connected income and FDAP income in the appropriate sections. The taxpayer applies the deductions, credits, and treaty provisions permitted for the tax year.
Common Mistakes and How to Avoid Them
Processing setbacks often occur when Form 1040-NR includes errors that the taxpayer could have avoided. A thorough identification of these issues strengthens filing accuracy and supports the verification steps performed by the Internal Revenue Service. A taxpayer’s correction of these problems before submission improves processing efficiency and reduces correspondence delays. Accurate preparation by the taxpayer ensures that reported income, withholding, and treaty claims align with IRS requirements.
- Missing Required Attachments: Taxpayers often submit returns without Forms W-2, 1042-S, or 1099, which prevents verification of withholding and reported amounts. The taxpayer must attach every required form to support the figures listed on the return.
- Incorrect Filing Status Selection: Some taxpayers choose ineligible filing statuses, which disrupt credit and deduction calculations. The taxpayer must verify eligibility for the nonresident filing status options.
- Unsigned Returns: Returns submitted without signatures cannot be processed. The taxpayer must sign all designated areas before filing.
- Mismatched Identification Numbers: SSN or ITIN discrepancies create conflicts during IRS matching procedures. The taxpayer must confirm that all identifying numbers match official documentation.
- Incomplete Income Reporting: Required items such as FDAP income or effectively connected income are sometimes omitted. The taxpayer must report each income type on the correct line to ensure full disclosure.
What Happens After You File
The Internal Revenue Service reviews Form 1040-NR and verifies income information with employers. Withholding agents and financial institutions provide records that support effectively connected income and FDAP income. The agency evaluates gains, business income, deductions, credits, and treaty claims from a foreign country.
The agency may request clarification when property entries, payments, or withholding records appear inconsistent. Refunds may take additional time when filings include FDAP income, real property interests, or foreign partner taxes. Taxpayers maintain copies of filings, payment confirmations, and U.S. source documents for future review.

FAQs
How does FDAP income differ from effectively connected income for Form 1040-NR?
FDAP income includes passive items such as dividends, interest, or periodical gains. Effectively connected income relates to activity linked to a U.S. trade or business and includes wages, business income, or capital gains tied to that activity. Each category remains subject to different rules when the Internal Revenue Service reviews the return.
When does a nonresident qualify to file Form 1040-NR as a resident alien for part of the year?
A nonresident qualifies when the individual meets the substantial presence test for part of the year and remains a nonresident for the remaining period. This classification is generally considered a dual-status position for income tax purposes. The filing rules require separate reporting sections that reflect each status.
How do tax treaties influence capital gains or wages reported on Form 1040-NR?
A treaty may reduce liability for wages, capital gains, or business income when an eligible taxpayer qualifies under the subject provisions. Some treaty articles include examples that clarify the treatment of amounts received from a foreign country. The Internal Revenue Service reviews treaty claims according to guidance found on the pages last reviewed or updated.
What filing status options apply to nonresidents completing Form 1040-NR?
Nonresidents select single, married filing separately, or qualifying widow(er) because these categories apply to individuals who do not meet resident alien requirements. The Internal Revenue Service evaluates eligibility before accepting the filing status. Documentation must match official records published on the page last reviewed.
Can a nonresident amend Form 1040-NR when income includes domestic iron ore or similar items?
A nonresident may amend using Form 1040-X when corrections apply to income categories, including domestic iron ore or items reported as effectively connected income. The amended return must reference the correct tax year and include supporting documentation. Secure IRS pages display a padlock icon that indicates protected submission access.
