Form 1040-ES (NR): U.S. Estimated Tax for Nonresident Alien Individuals – A Plain English Guide (2011)
What Form 1040-ES (NR) Is For
Form 1040-ES (NR) is the package nonresident aliens use to calculate and pay estimated taxes throughout the year on income that isn't subject to withholding. Think of estimated tax as the ""pay-as-you-go"" system for people who don't have an employer automatically taking taxes out of their paychecks. This form is specifically designed for individuals who aren't U.S. citizens or permanent residents but earn income from U.S. sources.
The form serves two main purposes. First, it helps you figure out whether you need to make estimated tax payments at all. Second, it provides payment vouchers you mail to the IRS with your quarterly payments. The 2011 version includes a detailed worksheet to calculate your expected tax liability based on your anticipated income, deductions, exemptions, and credits for the year.
Nonresident aliens typically need this form when they earn income that's effectively connected with a U.S. trade or business—such as income from self-employment, rental properties, or business activities—where no taxes are automatically withheld. The form also addresses income not effectively connected with a U.S. business, which is generally taxed at a flat 30% rate (or lower treaty rate).
When You’d Use Form 1040-ES (NR)
Including Late and Amended Situations
You must make estimated tax payments for 2011 if two conditions apply: you expect to owe at least $1,000 in tax after subtracting withholding and refundable credits, and your withholding and credits will be less than the smaller of either 90% of your 2011 tax or 100% of your 2010 tax (your 2010 return must cover all 12 months). Higher-income taxpayers—those with adjusted gross income over $150,000 in 2010—must substitute 110% for that 100% figure.
For the 2011 tax year, payment due dates were April 18, June 15, September 15, 2011, and January 17, 2012. If you had wages subject to U.S. withholding, you could either pay everything by April 18 or split it into four equal installments. Without wage withholding, you could pay everything by June 15 or divide it into three payments: half by June 15, a quarter by September 15, and a quarter by January 17, 2012. Special rules applied to farmers and fishermen, who could pay all estimated tax by January 17, 2012, or file their complete return by March 1, 2012, and avoid penalties entirely.
If your income, deductions, or tax situation changed significantly during the year, you could amend your estimated tax payments by refiguring your total estimated tax and adjusting remaining payments accordingly. The form doesn't explicitly label this as ""amended,"" but you simply recalculate and adjust future payments. If you made insufficient payments for earlier quarters, you might owe penalties, though certain circumstances allow penalty waivers.
Late payments trigger underpayment penalties calculated from the due date until you pay. The penalty applies even if you ultimately receive a refund on your tax return. However, you could avoid making the fourth payment due January 17, 2012, if you filed your complete 2011 return by January 31, 2012, and paid all taxes owed.

Key Rules or Details for 2011
The threshold rule is straightforward: if you expect to owe less than $1,000 after withholding and credits, you don't need to make estimated payments. But once you cross that threshold, the safe harbor rules kick in—you need to prepay either 90% of your current year's tax or 100% of last year's tax (110% if you're a higher earner) to avoid penalties.
Nonresident aliens face unique restrictions. You cannot make joint estimated tax payments with your spouse if either of you is a nonresident alien. Your filing status determines which tax rate schedule you use, and these differ significantly from the schedules U.S. residents use. For 2011, the personal exemption amount was $3,700 per person.
The form distinguishes between two types of income. Income effectively connected with a U.S. trade or business gets taxed at graduated rates (just like U.S. citizens), while income not effectively connected—such as certain dividends, interest, or royalties—generally gets taxed at a flat 30% rate. You multiply that not-effectively-connected income by 30% (or a lower treaty rate if applicable) and add it to your effectively connected tax.
Self-employment deserves special mention. For 2011, the self-employment tax calculation changed temporarily. The rate dropped to 13.3% (from the usual 15.3%), with the social security portion at 10.4% instead of 12.4%, up to the wage limit of $106,800. The deduction for self-employment tax also changed—instead of simply deducting half of the self-employment tax, you needed to use a special worksheet that calculated an ""employer's equivalent portion.""
The IRS doesn't send reminder notices for estimated tax payments. You must track the due dates yourself and make timely payments. Postmark dates count as payment dates for mailed payments.
Step-by-Step (High Level)
How to Complete the Form
Start with the 2011 Estimated Tax Worksheet on page 6 of the form package. Line 1 asks for your expected adjusted gross income for 2011. Use your 2010 tax return as a baseline, but adjust for any expected changes in income, considering the ""What's New"" items listed in the form. If you're self-employed, remember to use the special worksheet on page 5 to calculate your self-employment tax deduction properly.
Next, subtract your estimated itemized deductions (or standard deduction if applicable) and multiply $3,700 by your number of personal exemptions. The result is your taxable income. Apply the appropriate 2011 tax rate schedule based on your filing status—single, married filing separately, qualifying widow(er), or estate/trust. If you have qualified dividends or capital gains, you may need to consult Publication 505 for special calculations.
Add any alternative minimum tax from Form 6251 and other applicable taxes. Subtract any credits you expect to claim—such as foreign tax credits, child tax credits, or education credits. This gives you your total estimated tax. The form then compares 90% of this amount against your prior year's tax to determine your required annual payment.
Enter your expected income tax withholding for the year on line 18. Subtract this from your required payment. If the result is less than $1,000, you don't need to make estimated payments. If it's $1,000 or more, divide the remaining amount into quarterly payments using the appropriate schedule based on whether you have wage withholding.
Finally, complete the payment vouchers. Print your name, address, and taxpayer identification number (Social Security number, Individual Taxpayer Identification Number, or Employer Identification Number for estates/trusts) on each voucher. Write only the amount you're paying by check in the box provided—don't include any overpayment from 2010 you're applying to the installment, as that's already been credited. Make checks payable to ""United States Treasury"" and write ""2011 Form 1040-ES (NR)"" and your identification number on them. Mail each voucher with your payment to the address specified in the form instructions.
Common Mistakes and How to Avoid Them
Many nonresident aliens incorrectly calculate their self-employment tax deduction for 2011. The old ""half of self-employment tax"" shortcut doesn't work for 2011 because of the temporary rate reduction. You must use the special worksheet on page 5 that accounts for the 10.4% rate and calculates the employer's equivalent portion. Skipping this step can throw off your entire estimated tax calculation.
Another frequent error involves failing to account for income not effectively connected with a U.S. business. Some taxpayers forget to multiply this income by 30% and add it to their total estimated tax on line 15. This income gets taxed separately at a flat rate, not as part of your graduated tax calculation, so it's easy to overlook if you're not careful.
People often confuse their required payment with what they'll actually owe. Remember, if you had high income in 2010 and expect lower income in 2011, you might be better off using the prior-year safe harbor (100% or 110% of last year's tax) even though you expect to owe less. Conversely, if 2011 will be a high-income year, basing payments on 90% of current year tax might save you from overpaying throughout the year.
Missing payment due dates is entirely avoidable but surprisingly common. The IRS doesn't send reminders. Mark your calendar for April 18, June 15, September 15, and January 17 (or the equivalent dates for your situation). If you're abroad and using foreign post, remember that only U.S. postmarks establish the payment date—foreign postmarks don't count.
Farmers and fishermen sometimes miss out on special benefits. If at least two-thirds of your gross income comes from farming or fishing, you can make just one payment by January 17 or file your complete return by March 1 and skip estimated payments entirely. Many miss this opportunity because they don't realize they qualify or they don't calculate the two-thirds threshold correctly.
Finally, taxpayers eligible for treaty benefits often fail to properly document them. If your tax treaty with the United States provides for reduced withholding rates or exemptions, you must file Form 8833 with your return when reporting income totaling more than $100,000 that qualifies for treaty benefits. Failing to file this disclosure form can jeopardize your treaty benefits.
What Happens After You File
Once you mail your payment voucher with a check, the IRS processes it and credits your tax account. You won't receive confirmation unless there's a problem or unless you specifically request a payment transcript. The IRS recommends keeping detailed records of all payments—note the date paid, check or money order number (or electronic confirmation number if paying online), amount paid, and any overpayment credit applied from the previous year. Page 7 of the form includes a helpful ""Record of Estimated Tax Payments"" table for tracking.
When you file your annual Form 1040-NR or Form 1040-NR-EZ (due April 17, 2012, for the 2011 tax year), you'll report your total estimated tax payments. If you paid too much, you'll receive a refund. If you paid too little, you'll owe additional tax and possibly penalties. The underpayment penalty is calculated based on the number of days each underpayment remained unpaid and the applicable IRS interest rate.
The IRS may calculate penalties automatically if you didn't pay enough estimated tax by each due date, even if you ultimately receive a refund. However, you can request a penalty waiver under certain circumstances, such as casualty, disaster, or unusual circumstances that made it unreasonable to make estimated payments. If you need to use the annualized income installment method (for uneven income throughout the year), you must file Form 2210 with your tax return to show you don't owe a penalty or to calculate the reduced penalty.
If you changed your name during the year—due to marriage, divorce, or other reasons—and made estimated tax payments under your former name, attach a statement to your 2011 income tax return listing all payments made and the name and identification number used for those payments. This ensures the IRS properly credits your account.
For payments involving withheld tax reported on Form 1042-S or Form 8805, expect longer processing times. The IRS notes these refunds may take up to six months due to additional verification requirements.
FAQs
What's the difference between Form 1040-ES and Form 1040-ES (NR)?
Form 1040-ES is for U.S. citizens and resident aliens, while Form 1040-ES (NR) is specifically designed for nonresident aliens. The forms differ in several ways: the tax rate schedules vary, nonresident aliens can't make joint estimated payments even if married, and the calculation of income includes special considerations for income effectively connected versus not effectively connected with a U.S. business. Nonresident aliens must use the NR version and cannot substitute the regular form.
Can I pay more than four times a year if I want to?
Yes. The form specifically encourages making more frequent payments if that works better for your situation. Simply make copies of unused payment vouchers, complete them, and mail them with your payments. The key is ensuring the total of amounts paid during each payment period equals at least the required amount by that period's due date. Additional payments won't eliminate penalties for earlier underpayments, but they can help you manage cash flow and ensure you don't fall short by year-end.
What if I earn income late in the year and didn't make earlier payments?
If you had no income subject to estimated tax during the first payment period but circumstances changed later in the year, you should use the annualized income installment method. This method accounts for uneven income and can lower or eliminate required payments for earlier periods when you had no income. You'll need to file Form 2210, including Schedule AI (Annualized Income Installment), with your 2011 tax return to show your calculation, even if you don't owe a penalty. Publication 505, Chapter 2, provides detailed instructions for this method.
I'm in the U.S. on an F-1 student visa. Do I need to file Form 1040-ES (NR)?
Students on F, J, M, or Q visas are generally ""exempt individuals"" for purposes of the substantial presence test, meaning you're likely a nonresident alien. If you have income effectively connected with a U.S. business (such as self-employment income beyond allowed employment) that isn't subject to withholding, you might need to make estimated payments using Form 1040-ES (NR). However, most students only have scholarship income or wages from allowed employment with proper withholding, so estimated payments aren't needed. If your only income is wages with full withholding, you don't need this form.
How do I know if I should use 90% of current year tax or 100% of prior year tax?
Choose whichever option results in a lower required payment. If your 2011 income will be significantly higher than 2010, use 100% of your 2010 tax (or 110% if your 2010 AGI exceeded $150,000 for most filing statuses). This lets you pay based on the known, lower amount. If 2011 income will be similar or lower than 2010, use 90% of estimated 2011 tax to avoid overpaying. You're not locked into one method—the IRS simply requires you to meet the smaller of the two amounts to avoid penalties.
What happens if I become a resident alien partway through 2011?
You'll have a dual-status tax year, which is explained in Chapter 6 of Publication 519. Your residency starting date depends on whether you meet the green card test or substantial presence test. For the part of the year you're a nonresident alien, you use Form 1040-ES (NR) rules and pay estimated tax on effectively connected income. After becoming a resident, you follow Form 1040-ES rules for U.S. residents. Your annual return will be a dual-status return, typically a Form 1040NR with ""Dual-Status Return"" written across the top and a statement attached showing the income and deductions for each period.
Can I pay estimated taxes electronically instead of mailing vouchers?
Yes. The 2011 form package mentions electronic payment options including the Electronic Federal Tax Payment System (EFTPS) and credit or debit card payments. Electronic payment helps ensure timely receipt and gives you immediate confirmation. Visit IRS.gov and look for electronic payment options (shown as www.irs.gov/e-pay in the 2011 form). If you pay electronically, you don't need to mail payment vouchers, but you should still keep the vouchers with your records showing when payments were required and what you paid.
Note: This guide covers the 2011 tax year Form 1040-ES (NR). Tax laws, forms, and procedures change regularly. Always use the current year's forms and instructions when filing your own taxes, and consult Publication 519 (U.S. Tax Guide for Aliens) or a qualified tax professional for guidance specific to your situation.
