Form 1040 must be filed by all taxpayers in the USA who have income exceeding the established threshold. This requirement applies to citizens, residents, and some non-residents working or earning income in the USA.
The W-2 form is used for employees whose employer withholds taxes. The 1099 form is for self-employed individuals and contractors who receive income without tax withholding and report to the IRS themselves.
The employer is required to issue the W-2 form by January 31. The 1099 form (for example, 1099-NEC) must also be sent to the recipient by January 31 so that they have enough time to prepare their tax return on time.
First, contact your employer. If they do not respond, reach out to the IRS. You can use Form 4852 instead of the W-2, indicating your income based on your paystubs and bank statements.
Contact the client. If they haven’t responded, please proceed to include the income in the declaration. The IRS mandates the reporting of all income, even in the absence of a form. Use bank data and contracts to calculate the amount.
You can file aon ex4868 (an RM 4868)—an automatic 6-month extension for filing. But the extension doesn’t excuse you from paying any tax due by April 15.
This is the test by which the IRS determines whether you are a tax resident. If you have been in the U.S. for 183 days over the past 3 years (according to the formula), you are considered a resident and are required to report as a citizen.
Form 1040-NR is filed by non-residents who have earned U.S. income— for example, students, interns, income-earning tourists, investors, or temporary workers who do not meet the requirements of a tax resident.
