Tax forms you’ll receive from CU
There are two important income reporting documents you may receive from CU — Form W-2 and/or Form 1042-S.
Taxable wages are reported on Form W-2.
Most commonly, treaty-exempt wages and taxable and treaty-exempt nonqualified scholarship are reported on Form 1042-S.
Form W-2 is sent in late January, and Form 1042-S is sent in mid-February.
They W-2 reports all wages paid by the university along with the type and amount of taxes already deducted from those wages. To learn more about the W-2, including an interactive graphic that explains each field on the form, visit the W-2 info page.
Form 1042-S reports treaty-exempt compensation, as well as taxable and treaty-exempt nonqualified scholarship/stipend/fellowship income. If you receive more than one of these types of income, you may receive multiple 1042-S forms for a given tax year.
Tax forms you’ll need to submit
Nonresident aliens with U.S.-sourced income are required to file income tax returns with both the federal taxing authority and the state taxing authority for each state in which income was earned, unless it is a state with no income tax. Taxing agencies by state can be found here.
Employees who are eligible to receive an up-front tax treaty benefit must submit Form 8233 — Exemption from Withholding on Compensation for Independent and Certain Dependent Personal Services of a Nonresident Alien Individual — to the International Tax Office.
Completing this form allows eligible, nonresident international employees to reduce their federal and state income tax withholdings, where allowable, under the tax treaty agreement between the U.S. and the employee's country of tax residency. To establish treaty eligibility and complete Form 8233 employees must meet with a CU international tax specialist.
IRS Form 1040-NR, U.S. Nonresident Alien Income Tax Return, is the U.S. income tax return form designated for nonresident aliens to file and must be filed annually with the Internal Revenue Service to report U.S. sourced income.
Do not use Form 1040 to file for a year when you are considered a nonresident for U.S. tax purposes. Use of the incorrect tax form will result in your requirement to submit an amended tax return.
Form DR 0104
Colorado Form DR 0104 is the standard income tax return form for the State of Colorado and must be filed annually.
If you earned income in a state other than Colorado, view taxing agencies by state here.
IRS Form 8843, Statement for Exempt Individuals and Individuals with a Medical Condition, must be filed annually by nonresident F or J visa holders.
To declare your U.S. presence as a nonresident alien, you must file from 8843 even if you received no income from U.S. sources during the year.
