Form 8233

What Is Form 8233?

Form 8233 is an IRS-issued form filed by a non-resident alien (NRA) employee. By filing Form 8233, they are looking to claim an exemption from Federal Income Tax Withholding (FITW) based on a tax treaty. 

How Does a Tax Treaty Work? 

The U.S. has tax treaties with multiple countries. Under these treaties, residents of foreign countries who receive compensation for both independent and dependent personal services in the States are either taxed at a reduced rate or exempt from certain taxes on their income. These reduced rates and exemptions vary across countries and items of income. 

The same goes for U.S. residents or citizens under these treaties—if they work in a foreign country, U.S. residents/citizens are eligible for a tax reduction or an exemption from certain foreign taxes on their income. 

What Do Employers Need to Know about Form 8233? 

If you’ve hired an NRA who would like to claim a tax treaty exemption, they must fill out Form 8233. NRA employees must provide a Taxpayer Identification Number (TIN) on the form, which in most cases, is a Social Security number (SSN).

If your employee does not have or is not eligible for an SSN, they must apply for an Individual Taxpayer Identification Number (ITIN). To do this, they must file Form W-7 and provide proof they are not eligible for an SSN (this proof can be a rejected Form SS-5). 

It can take several weeks for the IRS to notify your employee of their ITIN status. In the meantime, they may attach a copy of their submitted W-7 and rejected Form SS-5 to Form 8233 and submit it to you. 

Form 8233 Submission to the IRS

Employers must review Form 8233 and provide their information and signature in Part IV—Withholding Agent Acceptance and Certification. The form must be mailed or faxed to the IRS within five days after it is approved and signed. Be sure to provide a copy of Form 8233 to your NRA employee and keep a copy for yourself. 

If the IRS rejects your employee’s Form 8233, you must immediately begin withholding the applicable taxes from their paychecks.
