Form W-4
Every nonresident working in the U.S. must complete a W-4 when starting a new job. This form is used to determine exactly how much tax should be withheld from the nonresident’s paycheck.
Sprintax Calculus streamlines the process of accurately completing W-4 forms for each member of your nonresident population.
Form W-8BEN
Nonresidents can potentially reduce their tax liability by claiming tax treaty benefits. In order to avail of a treaty relief, nonresidents must complete a form W-8BEN.
Sprintax Calculus will outline the tax treaties available to your nonresidents and prepare Form W-8BEN as needed.
Form W-8BEN-E
By completing a Form W-8BEN-E (also known as a Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting), foreign vendors can claim a reduction in tax by availing of tax treaty benefits.
With Sprintax Calculus, Form W-8BEN-E for foreign vendors is created automatically.
Form 8233
Every nonresident who earns a certain type of scholarship, personal services or fellowship income (including compensatory scholarship or fellowship income from the same withholding agent) is required to file a Form 8233. This form can also be used to claim exemption from withholding for certain personal services, because of an income tax treaty.
Sprintax Calculus helps your nonresidents prepare the tax documents they need – including Form 8233 – to remain compliant in the US.
Form W-7
This form is used by nonresidents who are not eligible for a Social Security Number and need to apply for an Individual Taxpayer Identification Number (ITIN) to file a federal tax return. Where a nonresident requires an ITIN, Sprintax Calculus will quickly help them to complete their W-7.
Form W-9
Form W-9 is used to provide and certify a Taxpayer Identification Number (TIN) and to verify that the nonresident is not subject to backup withholding.
Sprintax Calculus will support any member of your nonresident population who requires this document.
Form SS-5
Form SS-5 is the application used to request a U.S. Social Security Number (SSN) from the Social Security Administration (SSA). It’s also used to replace a lost or stolen Social Security card or to update information, such as a name change.
Sprintax Calculus will provide a completed Form SS-5 for any nonresident who requires a SSN.
Form 1042-S
Form 1042-S is the official information return used to report U.S. source income paid to nonresidents and other foreign persons. Issued by the withholding agent to both the payee and the IRS, it covers income exempt under a tax treaty (such as wages, scholarships, and fellowships), independent personal services income, royalties, awards, prizes, gambling winnings, and deposit interest. The form must be provided to recipients by March 15 of the year following payment.

Sprintax Forms was originally launched to help nonresidents in the U.S. ensure they pay the correct amount of tax on their income and claim any tax treaty benefits they are entitled to.
Sprintax Calculus, on the other hand, was developed to help U.S. organizations navigate nonresident tax withholding efficiently.
Today, Sprintax Forms has been fully incorporated into Sprintax Calculus, combining both functionalities into a single, streamlined solution.
