IS YOUR COMPANY ACTIVE IN THE UNITED STATES AND DO YOU WANT TO CONTROL YOUR COSTS? WE SUPPORT YOU IN MANAGING W-8 AND W-9 FORMS SO THAT YOU REMAIN FULLY COMPLIANT WITH IRS RULES.
Form W-9, officially titled “Request for Taxpayer Identification Number and Certification”, enables the US Internal Revenue Service (IRS) to collect the information needed to identify and confirm taxpayers who hold US citizenship, permanent residency, or who are entities established in the United States.
W-8 forms constitute a set of documents designed to confirm the tax status of a non-resident or foreign entity in the United States and to manage withholding tax on income from US sources. They also make it possible to claim the benefit of tax treaties.
Form W-9 applies to US taxpayers (for example local self-employed workers and freelancers), while W-8 forms apply to foreign companies and individuals who are non-residents of the United States.
These documents play an essential role in meeting tax obligations and avoiding difficulties with the IRS in the United States.
W-8 and W-9 forms are required in many situations to maintain US tax compliance. Here are the circumstances in which each form must be completed:
This form provides an organisation (such as an employer, a bank or a client) with the Taxpayer Identification Number (TIN), which may be a Social Security Number (SSN) or an Employer Identification Number (EIN).
It is frequently used by self-employed workers and service providers to communicate their TIN to their clients, thereby enabling accurate reporting to the IRS.
Completed by foreign companies or individuals in order to confirm non-resident status and to claim a reduced rate of withholding tax under a tax treaty between their country of residence and the United States. Several variants exist, each covering specific cases. The most frequently used are:
-W-8BEN : “Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting (Individuals)”.
Completed by foreign individuals to confirm non-resident status and to claim reduced withholding under a tax treaty between their country of residence and the United States.
-W-8BEN-E : “Certificate of Status of Beneficial Owner for United States Tax Withholding and Reporting (Entities)”.
Completed by foreign entities to confirm non-resident status and to claim reduced withholding under a tax treaty.
-W-8ECI : “Certificate of Foreign Person's Claim That Income Is Effectively Connected With the Conduct of a Trade or Business in the United States”.
Completed by non-resident companies or individuals to confirm that certain income is effectively connected with the conduct of a trade or business in the United States and is therefore taxed as US-source income.
-W-8EXP : “Certificate of Foreign Government or Other Foreign Organization for United States Tax Withholding”.
Completed by foreign governments, international organisations, central banks and other exempt entities to confirm their status and obtain an exemption from withholding tax.
-W-8IMY : “Certificate of Foreign Intermediary, Foreign Flow-Through Entity, or Certain U.S. Branches for United States Tax Withholding and Reporting”.
Completed by foreign intermediaries, flow-through entities and certain US branches to confirm their status.
Do you wish to enter the US market while avoiding unnecessary bureaucracy, but are you encountering the obstacles listed below?
Understanding the precise requirements and subtleties of US tax legislation often proves difficult without specialised knowledge.
Errors in the information provided, including incorrect tax identification numbers, may result in incorrect tax withholdings and penalties.
Changes in company structure or the status of beneficiaries require frequent updates to the forms, which can become burdensome.
For entities operating internationally, aligning tax data with local and US rules can prove complex.
Insufficient knowledge of tax treaties between the United States and other countries may result in the application of incorrect withholding tax rates.
Meeting strict filing deadlines in order to avoid additional penalties and withholding taxes can present logistical difficulties.
