Whether you’re looking to start a new business venture or planning on diving deeper into the financial aspects of your current enterprise, there are certain essential documents you need to familiarize yourself with. One of these important documents is the W-9 form. This article will guide you through understanding how to fill out this vital tax form in 2025, its main purpose, and who needs to complete it. Let’s get started.

What Is a W-9 Form?

It is a document commonly issued in the United States. It is used for businesses and individuals to provide their taxpayer details to banks, employers, or other entities that may require it for various financial transactions. The document itself is straightforward, containing a set of questions that need to be completed. These questions mainly focus on details such as the taxpayer’s business name, EIN or SSN.

The W-9 document is often considered a cousin to the W-4 form, which individuals working in a company fill out for their employers. While the W-4 is used by employers to show the amount of income tax to withhold from their pay, the W-9 serves a different purpose. Independent contractors, freelancers, and people who are self-employed need to provide this document to the entities they work for. Generally, it’s important for businesses to have this document on file for their records.

W-9 Form Purpose

The main purpose of this paper is to collect accurate identification information from taxpayers. It is especially important for companies that make certain types of payments to report those payments to the IRS, such as dividends, interest, or payments made for a trade.

The W-9 acts as a formal request for the taxpayer’s TIN. By providing this information, the recipient of the document can correctly report the payments made to the IRS. If a firm pays out $600 or more in a tax year, they are required to report these payments by filling out a 1099 form with the IRS. The information provided on the tax paper allows the recipient or firm to complete this 1099 form accurately.

Who Needs to Complete a W-9?

Understanding who needs to complete the W-9 paper is important for ensuring proper tax compliance and reporting. Generally, the document is required to be completed by any company or individual that:

• are earning dividends or interests;
• are providing services to another enterprise or individual;
• are involved in various types of transactions that require tax reporting.

For companies, this often includes LLCs, partnerships, and sole proprietors. For individual taxpayers, it’s often those receiving income from consulting, freelance work, or any other self-employment activities.

Additionally, landlords often require this record from their tenants. This is because the rent payments they obtain are considered taxable income. Having a completed W-9 record, landlords can provide accurate information when reporting this income to the IRS.
