Form 1040-C - U.S. Departing Alien Income Tax Return

Form 1040-C, U.S. Departing Alien Income Tax Return, is filed by certain aliens leaving the United States to report income received or expected for the tax year up to the date of departure and to pay the tax due. Most resident and nonresident aliens who intend to leave the country must obtain a certificate of compliance, often called a sailing or departure permit, showing they have met their U.S. tax obligations, and Form 1040-C is used in that process. The form is not a final return; it is a way to settle tax before departure, and the departing alien still files a regular Form 1040 or Form 1040-NR for the full year afterward. Certain aliens are exempt from the departure permit requirement, such as some employees on short assignments and certain students. Because leaving without meeting the requirement can cause complications, departing aliens who are not exempt should determine whether they must file Form 1040-C before they go.

A sailing permit, also called a departure permit or certificate of compliance, is documentation from the IRS confirming that a departing alien has paid or arranged to pay their U.S. tax obligations, and Form 1040-C is the return used to determine and settle that tax before leaving. Aliens who are required to obtain the permit generally must visit an IRS office before departure, file Form 1040-C or, in some cases, Form 2063 for those with no taxable income, and show that their taxes are paid or secured. The permit must usually be obtained within 30 days before the planned departure date. Some aliens are exempt from the requirement, including certain government-related individuals, students, and short-term visitors with limited income. Because Form 1040-C is the mechanism for computing the tax tied to the sailing permit, departing aliens who are not exempt should prepare it as part of obtaining the permit, then file their regular annual return for the full year.

Form 1040-C does not replace your regular annual tax return; it is an interim filing used to settle tax before departing the United States. After leaving, the departing alien must still file the appropriate year-end return, either Form 1040 if a resident or Form 1040-NR if a nonresident, covering the entire tax year. Any tax paid with Form 1040-C is credited against the tax shown on that final return, and any overpayment can be refunded when the year-end return is filed. The purpose of Form 1040-C is to ensure that aliens leaving the country have addressed their U.S. tax liability up to the departure date, not to finalize the year's tax. Because the year-end return reconciles the full year and accounts for the Form 1040-C payment, departing aliens should keep their Form 1040-C and payment records to claim credit later. Treating Form 1040-C as the only filing would leave the regular return unfiled, so both are generally required.

Form 1040-C must generally be filed before a departing alien who is subject to the requirement leaves the United States, in connection with obtaining the certificate of compliance. The departing alien typically must obtain the sailing or departure permit within 30 days before the intended departure date, which involves filing Form 1040-C and paying or securing the tax due. Filing too early may not reflect the final pre-departure income, while waiting until the last moment risks delays in obtaining the permit. The form reports income for the year through the departure date and any income expected for the remainder of the year. Because the permit is tied to the departure date and the process occurs at an IRS office, departing aliens should plan to complete Form 1040-C in the weeks before leaving. The regular year-end return remains due on its normal schedule after departure, so the Form 1040-C timing is separate from the annual filing deadline.

Several categories of aliens are exempt from the departure permit requirement and therefore from filing Form 1040-C, depending on their status and income. Exemptions commonly include certain foreign government and international organization employees and their households, alien students, industrial trainees, and exchange visitors present on specific visas who received no taxable U.S. income other than allowances, and alien visitors for business or pleasure on certain visas who stayed briefly and earned no taxable U.S. income. Aliens passing through the United States and certain residents of contiguous countries who commute may also be exempt. The exemptions are specific and depend on visa category, length of stay, and whether taxable U.S. income was received. Because the rules are detailed and an alien who is not exempt must obtain the permit before leaving, departing aliens should confirm whether their particular situation qualifies for an exemption, and if not, prepare Form 1040-C as part of obtaining the certificate of compliance before departure.
