CPT student tax essentials: what you need to know

Curricular Practical Training (CPT) is an excellent opportunity for F-1 students to gain practical experience in their field of study.

Although, one thing you might not have considered is the tax implications of CPT income as a nonresident in the U.S.

In this guide, we provide a comprehensive overview of what you can expect when it comes to CPT student taxes.

What is Curricular Practical Training?

Curricular Practical Training (CPT) is a type of off-campus work authorization for F-1 students.

It allows students to gain practical experience directly related to their major or field of study.

CPT can be part-time or full-time and must be an integral part of the curriculum, such as an internship, cooperative education, or any other type of required practicum.

Authorization for CPT is provided by the Designated School Official (DSO) at your institution and must be completed before starting your employment.

Do I have to pay taxes on my CPT income?

Yes, CPT income is subject to federal and state income taxes.

The amount of tax you owe depends on your earnings and the tax rates applicable in the state where you work.

It’s important to have the correct amount of tax withheld from your paycheck to avoid any penalties or underpayment issues.

Understanding tax residency: Resident vs. Nonresident Alien

Your U.S. tax responsibilities are determined by your tax residency status, which plays a key role in how your income is taxed and what tax benefits you can claim.

For most international students on an F-1 visa, this status is nonresident alien during their first five calendar years in the United States.

Nonresident aliens are subject to different tax rules than U.S. residents. They generally have limited access to tax deductions and credits, and only certain types of income are taxable.

Once you have been in the U.S. for more than five calendar years, your tax status may change. At that point, you may qualify as a resident alien if you pass the Substantial Presence Test. This test looks at how many days you were physically present in the U.S. during the current year and the two previous years.

Resident aliens are taxed in the same way as U.S. citizens and may be eligible for a wider range of tax benefits.

How to identify your tax residency status

• Nonresident Alien: Most F-1 students remain nonresident aliens for tax purposes during their first five calendar years in the U.S.
• Resident Alien: After five years, you may become a resident alien if you meet the Substantial Presence Test.

Knowing your correct residency status is essential, as it determines your tax obligations and which IRS forms you are required to file.

Starting employment and Sprintax Forms

Before beginning employment in the U.S., international students and scholars must complete several important tax-related forms, such as those required to obtain a Social Security Number (SSN) or ensure correct tax withholding by their employer.

Sprintax Forms can help streamline this process by guiding users through the necessary paperwork based on their visa type, residency status, and income situation.

Sprintax Forms supports international workers at the start of their employment by preparing documents like the SSN application support letter and federal tax forms (including Form 8233 for claiming tax treaty benefits), helping ensure compliance from day one and reducing the risk of incorrect tax withholding.

What is the tax rate for CPT students?

As an F-1 student on CPT, your income is taxed at the same rate as U.S. residents.

However, as a nonresident alien for tax purposes, you may not be eligible for the same deductions and credits as U.S. citizens and resident aliens.

This can result in a higher CPT tax rate. It’s crucial to understand your tax obligations and plan accordingly.

Below are the tax rates for the 2025 tax year (taxes that will be filed in April 2026).

Am I exempt from paying tax while on CPT?

While you are not exempt from federal and state income taxes, you are generally exempt from paying Social Security and Medicare taxes on your CPT income. This exemption is based on your F-1 visa status and your nonresident alien status for tax purposes.

CPT student FICA tax exemption

Students working in the U.S. under Curricular Practical Training (CPT) may be exempt from paying FICA taxes, which include Social Security and Medicare, as long as they are classified as nonresident aliens for tax purposes.

This exemption applies because nonresident alien students on F-1 visas are not subject to FICA taxes while they maintain their student status.

However, once a student becomes a resident alien for tax purposes, typically after meeting the Substantial Presence Test, the FICA exemption no longer applies, and employers are required to withhold Social Security and Medicare taxes from their wages.

Understanding whether you qualify for the CPT FICA tax exemption can help ensure your paycheck is taxed correctly!

Be sure to inform your employer about this exemption so that these taxes are not mistakenly withheld from your paycheck.

If you are taxed incorrectly, you may end up paying too much in tax.

Alternatively, you could end up being undertaxed, which can potentially lead to future issues, such as visa/green Card rejections.

Are F-1 students on CPT entitled to a tax refund?

Whether you are entitled to a tax refund depends on several factors, including the amount of tax withheld from your paycheck and your total income for the year.

Essentially, if more tax was withheld than you owe, you could be eligible for a refund. 

However, nonresident aliens are not eligible for certain tax credits and deductions that U.S. citizens and residents can claim, which may impact the size of your refund.
