What is the difference between Form 1040 and Form 1040-NR?

Form 1040 is for US citizens and resident aliens reporting worldwide income. Form 1040-NR is for non-resident aliens reporting only US-source income. Non-residents cannot use Form 1040 unless they meet the substantial presence test or make a special election. If you hold an ITIN and live outside the US, you need Form 1040-NR.

Do I need to file a US tax return if I had no US income?

In most cases, no. But if you own a US LLC, you must file Form 5472 and a pro-forma Form 1120 regardless of income. Also, filing a return keeps your ITIN active since ITINs expire after 3 consecutive years of non-use per Rev Proc 2015-35. Even a zero-income return resets the clock.

Can I claim a tax refund using Form 1040-NR?

Yes. If taxes were withheld at the default 30% rate on dividends, interest, or royalties, but a treaty reduces your rate, you claim the difference as a refund. The IRS processes refunds within 6 to 8 weeks. You must file the return to receive the refund. Over 60 countries have US tax treaties with reduced withholding rates.

What happens if I miss the tax filing deadline?

If you owe taxes and miss April 15, the IRS charges 5% of unpaid taxes per month (up to 25%) plus 0.5% per month failure-to-pay penalty plus interest. If you are owed a refund, there is no penalty but you must file within 3 years to claim it. Non-residents abroad get automatic extension to June 15, but interest accrues from April 15.

Can I e-file Form 1040-NR with an ITIN?

Yes. The IRS accepts e-filed 1040-NR returns with ITINs. Not all software supports non-resident filings. Sprintax ($50-$150) and Glacier Tax Prep are built for non-residents. A CPA can also e-file on your behalf ($300-$800 for non-resident returns). E-filing is faster and reduces errors compared to paper.

Do I need a new ITIN every year to file taxes?

No. Your ITIN stays the same year to year. Renew only if it expired due to 3 years non-use or middle-digit retirement. Once renewed, your ITIN is valid until the next expiration trigger. There is no annual renewal requirement. The IRS charges $0 for renewal via Form W-7.

What is effectively connected income (ECI)?

ECI is income connected to a US trade or business: wages, salary, self-employment income, business profits from a US LLC, and rental income elected as ECI. ECI is taxed at graduated rates (10% to 37%) and you can take deductions against it. This is reported on the main section of Form 1040-NR.

What is FDAP income and how is it taxed?

FDAP stands for Fixed, Determinable, Annual, Periodical income. It includes passive income like dividends, interest, royalties, rents (if not ECI), and pensions. FDAP is taxed at a flat 30% rate unless a tax treaty reduces it. Tax is usually withheld at the source. You report it on Schedule NEC of Form 1040-NR.

How do I claim tax treaty benefits on Form 1040-NR?

Complete Schedule OI (Other Information) on Form 1040-NR. Identify your country of residence, cite the specific treaty article, and show the income amount eligible for the reduced rate. If tax was withheld at 30% but a treaty entitles you to a lower rate, claim the difference as a refund. File Form W-8BEN with payers for future payments.

How to File US Taxes with an ITIN

How Do Tax Treaty Benefits Work for ITIN Holders?

The US has income tax treaties with 60+ countries. These treaties reduce or eliminate US tax on certain income types. 5 income categories commonly qualify.

Dividends: Default 30% often reduced to 15%, 10%, or 0% depending on country
Interest: Many treaties reduce or eliminate the 30% withholding
Royalties: Software, patent, copyright royalties at reduced rates
Business profits: Some treaties exempt profits without a US permanent establishment
Personal services: Independent services may be exempt if under specified days in the US

Claim treaty benefits on Schedule OI. Cite the specific treaty article. File Form W-8BEN with payers. If tax was withheld at 30% but a treaty entitles you to less, claim the refund on your 1040-NR. For treaty-based ITIN applications without a tax return, see ITIN without tax return guide.

What Deductions Can Non-Resident Filers Claim?

Non-residents have limited but meaningful deduction options. All deductions must connect to effectively connected income.

No standard deduction for most non-residents

Unlike the $14,600 standard deduction for single US residents, non-residents must itemize on Schedule A. Exception: students and apprentices from India may claim the standard deduction under the US-India treaty.

State and local taxes: State income taxes paid, capped at $10,000 (SALT)
Charitable contributions: Donations to qualifying US charities only
Business expenses: Ordinary and necessary expenses on Schedule C
Rental expenses: Mortgage interest, property taxes, insurance, depreciation
Student loan interest: Up to $2,500 if qualifying

How Do You File Form 1040-NR Step by Step?

5 steps complete your non-resident filing.

Step 1: Gather Your Documents

W-2 (wages), 1099-NEC/MISC (freelance), 1099-DIV (dividends), 1099-INT (interest), 1042-S (non-resident withholding). You need your ITIN, passport info, and country of tax residence details.

Step 2: Determine Your Filing Status

Most non-residents file as single or married filing separately. Joint filing requires a Section 6013(g) election. Determine which treaty articles and reduced rates apply to your income.

Step 3: Complete Form 1040-NR

ITIN in SSN field. Foreign address. Report income on appropriate lines. Attach Schedule OI with visa type, days in US, and treaty claims. Schedule A for itemized deductions. Tax tables for computation.

Step 4: Report Tax Payments

Enter federal tax withheld from W-2, 1042-S, and 1099 forms. Include estimated tax payments. This section determines your refund or amount owed.

Step 5: Submit Your Return

E-file via Sprintax ($50-$150), Glacier Tax Prep, or through a CPA ($300-$800). Paper filing to IRS Austin, TX. If you need an ITIN simultaneously, attach Form W-7 and identity documents. See ITIN tax return parent guide.

What Are the Most Common Filing Mistakes to Avoid?

7 errors cause rejections or incorrect tax calculations.

Using Form 1040 instead of 1040-NR. Reporting worldwide income instead of US-source only. Claiming the standard deduction (not allowed for most non-residents). Forgetting Schedule OI. Missing the deadline because you assumed the June 15 extension applied when you received US wages. Not claiming treaty benefits you qualify for. Filing with an expired ITIN without attaching a renewal. Each mistake increases your tax bill or triggers IRS correspondence.

Ensure your ITIN is active before filing. If expired, see our ITIN renewal guide. For ITIN application mistakes, see our dedicated guide. For business owner filing, check our guide. For international student filing, see our student guide.
