Form 1040-NR

Form 1040-NR is the U.S. Nonresident Alien Income Tax Return, the federal income tax return a nonresident alien files with the IRS. The IRS describes it on its About Form 1040-NR page, which states that you may need to file the form if you “were a nonresident alien engaged in a trade or business in the United States,” or if you represented a deceased person, estate, or trust that would have to file. In plain terms, it is how a foreign person reports US-source income and income connected to US business activity, and then settles any tax due beyond what was already withheld.

What Form 1040-NR Covers

The return separates a nonresident’s income into two buckets, each taxed differently.

• Effectively connected income. Income that is effectively connected income with a US trade or business is reported on the main body of the return and taxed on a net basis at the same graduated rates that apply to US residents, after allowable deductions.
• Income not effectively connected. US-source income that is not effectively connected, such as fixed or determinable annual or periodical income, is reported on Schedule NEC. The IRS titles that schedule “Tax on Income Not Effectively Connected With a U.S. Trade or Business,” and this income is generally taxed at a flat statutory rate rather than graduated rates.

When a Foreign Contractor Has No Filing Obligation

For a US company engaging a foreign contractor, the threshold question is sourcing. Compensation for personal services is sourced to the place where the work is physically performed. A developer in Brazil who performs every hour of work from Brazil earns foreign-source income, which sits outside US taxation. That contractor generally has no US filing obligation and does not file Form 1040-NR for those payments.

The result flips when the contractor performs services on US soil. Work physically done inside the United States becomes US-source income. Depending on the facts, that US-source income can be effectively connected with a US trade or business and can create a Form 1040-NR filing obligation for the contractor, even if the engagement is short.

Filing Versus Withholding

Tax withheld at the source under the NRA withholding rules is a collection device, not a final accounting. A nonresident with effectively connected income generally still files Form 1040-NR to compute net tax against deductions and to reconcile it with amounts already withheld, which can leave a balance due or generate a refund. Withholding and filing are separate steps, and one does not automatically discharge the other.
