Yes, income from CPT (Curricular Practical Training) is generally taxable in the U.S. for F-1 students, but the specifics depend on several factors. Here’s a breakdown of the tax treatment of income you earn from CPT:

1. Federal Income Tax

• Yes, CPT income is subject to federal income tax just like any other employment income you earn while in the U.S.

• If you are working in the U.S. under CPT, your employer will typically withhold federal income taxes from your paycheck, based on the amount you earn.

• The tax rate will depend on your income level and your filing status, and it’s calculated according to the tax brackets established by the IRS. You will report this income on your annual tax return (Form 1040-NR for nonresident aliens).

2. Social Security and Medicare Taxes (FICA)

• Exemption for F-1 Students: As an F-1 student, you are generally exempt from Social Security and Medicare taxes (FICA) on your CPT earnings, as long as you are still in F-1 status and the work is authorized by Curricular Practical Training.

• Important Exception: If you work in a position that is not directly related to your field of study, or if you're on a visa status other than F-1, then you might lose this exemption and have to pay FICA taxes.

• If your employer mistakenly withholds FICA taxes from your paycheck, you can request a refund from the IRS by filing Form 843.

3. State and Local Taxes

• Just like other types of income, CPT earnings are also subject to state and local taxes (depending on the state and city you work in). For example, if you're working in California, you may have to pay California state income tax on your earnings.

• Some states, like Florida or Texas, don’t have a state income tax, so you wouldn’t have to worry about paying state tax in those states.

4. Tax Treaties and CPT

• Some countries have tax treaties with the U.S. that might reduce or eliminate the amount of federal income tax you have to pay. However, tax treaties typically do not exempt income earned through CPT. Most tax treaties apply to academic scholarships, fellowships, and sometimes research income, but they do not usually cover wages earned through CPT.

• If your home country has a treaty with the U.S., you can review the treaty provisions to see if there are any exceptions or reductions in the tax rate. If there is a relevant treaty benefit, you may need to submit Form 8233 to claim the tax exemption or reduction.

5. Do You Need to File a Tax Return for CPT Income?

• Yes, you must file a tax return if you earn income through CPT, even if it’s just a small amount. Your employer will provide you with a W-2 form at the end of the year, which will detail how much you earned and how much tax was withheld.

• If you're a nonresident alien (which most F-1 students are), you will file a Form 1040-NR (Nonresident Alien Income Tax Return) to report your CPT income. This will allow you to:

  • Report your taxable income.

  • Claim any applicable deductions or tax treaty benefits.

  • Receive a refund if too much federal income tax was withheld.

• Even if you didn’t earn much, you still need to file this return to be in compliance with U.S. tax laws.

6. Filing Requirements for Nonresident Aliens (F-1 Students):

• You’ll file Form 1040-NR to report income earned through CPT and any other U.S.-sourced income. This form is different from the Form 1040, which is for U.S. residents.

• Your employer will provide you with a W-2 form that shows your earnings and the amount of tax that has been withheld. You’ll use this form to complete your tax return.

7. Key Points to Remember

• CPT income is taxable under federal income tax, state income tax (if applicable), and local taxes (if applicable).

• As an F-1 student, you're generally exempt from Social Security and Medicare taxes (FICA taxes) on your CPT earnings.

• Even if your income is small, you must file a tax return to report your CPT income.

• Tax treaties may provide some relief, but they typically don’t apply to CPT earnings. Be sure to check if your country has a treaty and if it applies to your situation.

• If your employer incorrectly withholds FICA taxes, you can request a refund from the IRS.

Example:

Let’s say you worked a part-time job on CPT in 2024 and earned $8,000. Here’s how things might work:

1. Federal Taxes: You’ll have federal income tax withheld from your paycheck, based on your income. You’ll report this income on your Form 1040-NR when filing your taxes in 2025.

2. State Taxes: If you’re working in a state like California, your employer may also withhold California state income tax. You’ll report this on your tax return as well.

3. Social Security and Medicare: Since you’re an F-1 student, your employer should not be withholding Social Security and Medicare taxes on your earnings, but if they do, you can request a refund using Form 843.

After filing, you might receive a refund if too much tax was withheld, or you may owe additional taxes if your withholding was too low.

Conclusion:

To sum it up:

• Yes, your CPT earnings are generally taxable for federal income tax and state/local taxes (if applicable).

• No, you are typically exempt from FICA taxes (Social Security and Medicare) on your CPT income, as long as you are on F-1 status.

• You will need to file a tax return (Form 1040-NR) to report your CPT income and any taxes that were withheld, even if you didn’t earn a lot.
