Form 1040-NR Tax Year 2021 Filing Checklist
Overview of Form 1040-NR for Tax Year 2021
Form 1040-NR is the U.S. Nonresident Alien Income Tax Return used by nonresident aliens who engaged in trade or business in the United States or received U.S. source income during 2021. The tax year 2021 featured significant expansions under the American Rescue Plan Act, affecting certain tax credits; however, nonresident aliens faced substantial restrictions in claiming most benefits. The classification of income as effectively connected income or non-effectively connected income determines applicable tax rates, deductions, and credits.
Key 2021 Tax Year Provisions
American Rescue Plan Act Changes
The American Rescue Plan Act of 2021 made significant modifications to tax credits, with limited applicability to nonresident aliens. The Child Tax Credit has increased to $3,600 for qualifying children under the age of six and $3,000 for children ages six through seventeen. Nonresident aliens could claim this credit only if they resided in Canada, Mexico, or South Korea, qualified as U.S. nationals, or were students or business apprentices under Article 21(2) of the United States-India Income Tax Treaty.
Child and Dependent Care Credit Expansion
For 2021, the Child and Dependent Care Credit expanded dramatically through the American Rescue Plan Act. The limit on expenses increased to $8,000 for one qualifying person and $16,000 for two or more qualifying persons. The maximum credit percentage increased to fifty percent from the prior thirty-five percent—the credit is initially refundable for 2021 only. Nonresident aliens filing Form 1040-NR could claim this credit only if they or their spouse maintained a principal place of abode in the United States for more than half of 2021.
Premium Tax Credit Changes
The American Rescue Plan Act eliminated the limitation that household income could not exceed four hundred percent of the Federal Poverty Line when claiming the Premium Tax Credit for 2021 and 2022. However, nonresident aliens filing Form 1040-NR remained ineligible for the Premium Tax Credit regardless of these changes. The Premium Tax Credit expansion applied only to U.S. citizens and residents who were eligible for the credit, not to non-citizens or non-residents.

Standard Deduction and Charitable Contribution for Indian Students
Students and business apprentices eligible for benefits under Article 21(2) of the United States-India Income Tax Treaty who elected to use the standard deduction could claim a deduction for charitable cash contributions of up to $300 for the 2021 tax year. This represented a unique allowance because nonresident aliens generally cannot claim the standard deduction.
Filing Requirements and Restrictions
Credits Available to Nonresident Aliens
Nonresident aliens filing Form 1040-NR in 2021 faced substantial restrictions on which credits they could claim. The Child Tax Credit could be claimed only by residents of Canada, Mexico, South Korea, U.S. nationals, or students and business apprentices under the India treaty. The Credit for Other Dependents applied only to these same limited populations. The Foreign Tax Credit remained available and could be claimed on the Schedule C carry-forward for carry-back provisions.
The Retirement Savings Contributions Credit remained available to qualifying nonresident aliens. Nonresident aliens could not claim the Earned Income Tax Credit, Hope Credit, Lifetime Learning Credit, American Opportunity Tax Credit, or Adoption Credit.
Deduction Limitations
Nonresident aliens could claim deductions only to the extent those deductions were allocated and apportioned to income effectively connected with a United States trade or business. Taxpayers cannot claim deductions relating to exempt income or income not effectively connected with a trade or business. State and local income may be deducted, subject to the $10,000 limitation or $5,000 for individuals married and filing separately.
Charitable contributions to nonprofit organizations can be deducted only if they are linked to effectively connected income. Personal exemption deductions were not available for any tax year linked after December 31, 2017.
Filing Status Restrictions
Nonresident aliens filing Form 1040-NR could not use the Married Filing Jointly or Head of Household filing statuses. Available filing statuses were Single, Married Filing Separately, Qualifying Widow or Widower, Foreign Trust, or Foreign Estate. To use Qualifying Widow or Widower status, the nonresident alien needed to be a resident of Canada, Mexico, or South Korea or a United States national; have been married to a decedent who died during one of the two prior tax years; and have not remarried before the end of 2021.

Required Schedules and Documentation
Mandatory Schedules
Schedule OI, titled Other Information, was mandatory for all Form 1040-NR filers. Schedule NEC titled Tax on Income Not Effectively Connected With a U.S. Trade or Business was required for any nonresident alien who received income not effectively connected with a U.S. trade or business from U.S. sources.
Schedule A was required if claiming itemized deductions or if Indian students and business apprentices elected to claim the standard deduction. Numbered schedules from Form 1040, including Schedules 1, 2, and 3, might be required depending on additional income, taxes, or credits.
Supporting Forms
Form 8995 or Form 8995-A might be required if you claim the qualified business income deduction. Schedule 8812 was required for any nonresident alien claiming child tax credits or reporting advance Child Tax Credit payments received during 2021. Form 2441 was required if claiming the Child and Dependent Care Credit. Form 1116 needed to be completed and attached if claiming a foreign tax credit. Form 8833 needed to be attached if required for treaty benefit disclosure. Form 8843 needed to be filed if you claimed exemption from the substantial presence test.
Step-by-Step Filing Process
Step 1: Determine Nonresident Alien Status
Verify nonresident alien status by confirming you do not meet the green card test or substantial presence test for 2021. If you were a lawful permanent resident at any point during 2021, you meet the green card test. The substantial presence test is met if you were physically present in the United States for at least 31 days in 2021 and 183 days in the three-year period, including 2021, 2020, and 2019.
Step 2: Gather Income Documentation
Collect Forms W-2 showing wages, salaries, and tips from United States employment. Obtain Form 1042-S for U.S. source income, such as scholarships, interest, dividends, or rental income subject to withholding at source. Gather Form 1099 for dividends, interest, or other income. Collect Schedule K-1 forms from partnerships or S corporations. Obtain Forms SSA-1042S or RRB-1042S if you received Social Security or railroad retirement benefits. Retain Form 8288-A if you disposed of U.S. real property and Form 8805 if you were a partner in a U.S. partnership.
This checklist is for educational purposes only and does not constitute tax or legal advice. Always review official IRS instructions and consult a qualified professional for guidance.
Step 3: Classify Income as Effectively Connected or Not Effectively Connected
Determine if each income item is effectively connected with a U.S. trade or business. Effectively connected income is taxed at graduated rates on Form 1040-NR page 1 after allowing deductions properly allocated to that income. Income not effectively connected with a U.S. trade or business is generally taxed at a flat thirty percent rate or lower treaty rate on Schedule NEC, with limited deductions allowed.
Step 4: Report Effectively Connected Income
Enter wages, salaries, and tips on line 1a from Form W-2. Enter scholarship and fellowship grants on line 1b with Forms 1042-S or required statements attached. Enter total income exempt by treaty on line 1c as reported on Schedule OI Item L. Enter taxable interest on line 2b and dividends on line 3b. Report IRA distributions on line 4b and pensions and annuities on line 5b. Enter capital gain or loss on line 7. Report the other income from Schedule 1 on line 8. Add all income lines to calculate the total effectively connected income on line 9.
Step 5: Calculate Adjustments to Income
Enter adjustments to income from Schedule 1 on line 10a. These include educator expenses, health savings account deduction, moving expenses for members of the Armed Forces, one-half of self-employment tax if covered under an international social security agreement, and student loan interest deduction. Enter scholarship and fellowship grants excluded from income on line 10c. Calculate total adjustments on line 10d and subtract from line 9 to determine adjusted gross income on line 11.
Step 6: Determine Deductions
Enter itemized deductions from Schedule A on line 12a. Indian students and business apprentices eligible for Article 21(2) benefits may enter the standard deduction instead. Enter charitable contributions for certain residents of India on line 12b if applicable. Calculate total deductions on line 12c. Enter the qualified business income deduction from Form 8995 or Form 8995-A on line 13a. Add lines 12c and 13c and the amounts from lines 12c and 13c, then enter the total 14 from line 11 to calculate taxable income on line 15.
Step 7: Calculate Tax Liability
Calculate tax using the tax tables or tax rate schedules and enter on line 16. Add the amount from Schedule 2 on line 17. Enter the nonrefundable Child Tax Credit or Credit for Other Dependents from Schedule 8812 on line 19 if applicable. Enter credits from Schedule 3 on line 20. Calculate total credits on line 21 and subtract from line 18 to determine tax after credits on line 22.
This checklist is for educational purposes only and does not constitute tax or legal advice. Always review official IRS instructions and consult a qualified professional for guidance.
Step 8: Report Tax on Non-Effectively Connected Income
Enter income tax from Schedule NEC line 15 on line 23a if the income was not effectively connected with a U.S. trade or business. This represents the flat thirty percent or lower treaty rate tax applied to non-effectively connected income. Enter other taxes, including self-employment tax from Schedule 2 on line 23b. To calculate the total tax liability, add the amounts from lines 22 and 23d, and then enter the result on line 24.
Step 9: Report Withholdings and Payments
Enter the federal income tax withheld from Form W-2 on line 25a. Enter federal income tax withheld from Forms 1099 on line 25b. Enter federal income tax withheld from Form 8288-A on line 25f. Enter federal income tax withheld on income not effectively connected with a U.S. trade or business from Form 1042-S on line 25g. Enter estimated tax payments for 2021 and amounts applied from the 2020 return on line 26. Enter the refundable Child Tax Credit from Schedule 8812 if applicable, on line 28. Calculate total payments on line 33.
Step 10: Complete Schedule OI
Complete Schedule OI to provide the required information. Report your country of citizenship or nationality on Item A. Enter the country where you claim residence for tax purposes on Item B. Report your visa status on the appropriate items. If you are claiming tax treaty benefits, complete Item L by listing the country, the applicable tax treaty article, the number of months in prior years that the treaty benefit was claimed, and the amount of exempt income. Attach Form 8833 if required by the rules for disclosing tax treaties.
Step 11: Determine Refund or Amount Owed
Compare total payments on line 33 to total tax on line 24. If line 33 exceeds line 24, the difference represents the overpaid amount on line 34. Select how the refund will be applied on line 35a, either as a refund check or direct deposit. Enter the routing and account numbers you are using if selecting direct deposits on lines 35b through 35d. Enter the amount to be applied to the 2022 estimated tax on line 36. If line 33 is less than line 24, enter the amount owed on line 37.
Step 12: Sign and Date the Return
Sign and date Form 1040-NR under penalty of perjury. Enter your occupation on the signature line. If the IRS sent an Identity Protection Personal Identification Number, enter that PIN. Provide a phone number. If a paid preparer completed the return, the preparer must sign and enter their name, Preparer Tax Identification Number, firm information if applicable, and date.
Step 13: Assemble Supporting Documents
Attach all required supporting documents in the proper order. The cover page of Form 1040-NR comes first, followed by Schedule OI, Schedule NEC if applicable, Schedule A if used, numbered Form 1040 schedules in order, and supporting forms such as Schedule 8812, Form 2441, Form 1116, Form 8833, or Form 8843 as applicable. Attach all Forms W-2, Forms 1042-S, and any other income documentation.
Step 14: File by the Applicable Deadline
For tax year 2021, the filing deadline was April 18, 2022, for nonresident aliens who were employees receiving wages subject to U.S. income tax or who had an office or place of business in the United States. The April 18 date applied because Emancipation Day fell on Saturday, April 16, which moved the observance to Friday, April 1. This, in turn, pushed the tax filing deadline to Monday, April 18, 2022. If you were a non-employee without US-based wages or business, the deadline was June 15, 2022.
Step 15: Request Extension if Needed
If you are unable to file the return by the due date, please request an automatic extension by filing Form 4868 by the regular due date. Filing Form 4868 automatically extended the filing deadline to October 15, 2022, for tax year 2021 returns. The extension applied to the time to file, not the time to pay. Any tax due is outstanding as of the original due date to avoid interest and penalties.
Important Considerations
Recordkeeping Requirements
Retain Form 1040-NR and all supporting documentation, including Forms W-2, Forms 1042-S, and all schedules and attachments, for at least three years from the date of filing or two years from the date the tax was paid, whichever is later. Keep copies of all payment vouchers, cancelled checks, and mailing confirmations to verify timely filing and payment.
Treaty Benefits Documentation
If you are claiming treaty benefits, maintain documentation that verifies your resident status for tax purposes in the treaty country. Properly disclose treaty benefits on Schedule OI Item L and attach Form 8833 if required. Review tax treaty provisions between the United States and your country of residence for reduced withholding rates on dividends, interest, and royalties, and exemptions for certain income.

Dual Status Taxpayers
If your residency status changes from nonresident alien to resident during 2021, your alien tax filing requirements will change significantly. Dual-status taxpayers must file special returns that show and claim deductions for each period under different rules. Consult IRS Publication 519 for dual status requirements.
Self-Employment Tax
Nonresident aliens generally are not liable for self-employment tax unless covered by an international social security agreement between the United States and their country of residence, if covered by such an agreement, and having net earnings from self-employment of at least $400, file Schedule SE and deduct one-half of self-employment tax as an adjustment to income.
This checklist ensures accurate calculation and timely filing of 2021 income taxes for nonresident aliens using Form 1040-NR.
