Have you recently started freelancing under your own name and then considered forming an LLC, only to get confused about what changes on your W-9? Many freelancers assume that once they register an LLC, everything changes instantly\u2014from tax IDs to reporting\u2014but the reality is more nuanced.<\/p>\n\n\n\n
This article explains how your business structure affects your W-9, especially if you\u2019re moving from a sole proprietor setup to an LLC<\/a>. You\u2019ll learn which tax ID to use, how the IRS treats different LLC types, and how state-level differences in places like Delaware, Wyoming, California, and Texas can impact your setup.<\/p>\n\n\n\n Form W-9<\/a> is used to provide your taxpayer information to clients or businesses that pay you. It includes your legal name, business name (if applicable), and your Taxpayer Identification Number (TIN), which can be either a Social Security Number (SSN) or an Employer Identification Number (EIN).<\/p>\n\n\n\n If you\u2019re a freelancer or business owner, clients request this form so they can issue a Form 1099-NEC at the end of the year<\/a>. The IRS uses that information to match reported income with your tax return.<\/p>\n\n\n\n According to the Internal Revenue Service<\/a>, the W-9 is not submitted directly to the IRS but is used by the payer for reporting purposes.<\/p>\n\n\n\n The IRS has also released draft Form W-9 instructions (<\/strong>Rev. January 2026)<\/strong><\/a>, which highlight upcoming changes. These instructions are not finalized, but they provide insight into how reporting expectations may evolve.<\/p>\n\n\n\n In simple terms, the W-9 connects your business identity to how your income is reported at the federal level.<\/p>\n\n\n\n At the federal level, your business structure determines how you complete your W-9\u2014specifically, which name and tax ID you use.<\/p>\n\n\n\n If you are a sole proprietor<\/strong>, you and your business are considered the same entity. This means:<\/p>\n\n\n\n If you form a single-member LLC<\/strong>, the IRS usually treats it as a \u201cdisregarded entity\u201d by default. This means:<\/p>\n\n\n\n If your LLC has multiple members or elects corporate taxation, then:<\/p>\n\n\n\n One important update being discussed for 2026 is the expectation that sole proprietors will use their SSN on Form W-9 instead of an EIN in certain cases<\/strong>, reinforcing the idea that the individual, not the business, is the taxpayer.<\/p>\n\n\n\n At the state level, however, things work differently.<\/p>\n\n\n\n States do not issue their own version of the W-9. Instead, they focus on:<\/p>\n\n\n\n This means your W-9 stays a federal document<\/strong>, but your state setup can still influence how your business is structured and taxed overall.<\/p>\n\n\n\n Form Used:<\/strong> Federal W-9<\/p>\n\n\n\n Official Source:<\/strong>https:\/\/corp.delaware.gov<\/a><\/p>\n\n\n\n Delaware is widely known for its flexible business laws, which is why many entrepreneurs choose it for LLC formation, even if they don\u2019t live there.<\/p>\n\n\n\n Delaware focuses on business structure and legal flexibility rather than personal tax treatment for owners.<\/p>\n\n\n\n If you form an LLC in Delaware but operate as a single-member LLC, your W-9 may still resemble that of a sole proprietor. You will typically:<\/p>\n\n\n\n The state itself does not change how your W-9 works, but your LLC structure\u2014chosen during formation\u2014does.<\/p>\n\n\n\n Form Used:<\/strong> Federal W-9<\/p>\n\n\n\n Official Source:<\/strong>https:\/\/sos.wyo.gov<\/a><\/p>\n\n\n\n Wyoming is popular among freelancers due to its low fees and privacy protections.<\/p>\n\n\n\n No state income tax and minimal ongoing reporting requirements for LLCs.<\/p>\n\n\n\n Even if you form an LLC in Wyoming, your W-9 remains tied to your federal classification. A single-member LLC is still treated like a sole proprietorship unless you elect otherwise.<\/p>\n\n\n\n This means many freelancers in Wyoming continue using:<\/p>\n\n\n\n on the W-9, despite having an LLC registered.<\/p>\n\n\n\n Form Used:<\/strong> Federal W-9<\/p>\n\n\n\n Official Source:<\/strong>https:\/\/www.ftb.ca.gov<\/a><\/p>\n\n\n\n California has stricter rules compared to other states and imposes additional obligations on LLCs.<\/p>\n\n\n\n Annual LLC tax and fee requirements apply, even for small businesses.<\/p>\n\n\n\n While your W-9 remains unchanged at the federal level, forming an LLC in California adds financial and compliance responsibilities. If your LLC is taxed as a corporation or partnership, you will:<\/p>\n\n\n\n If it remains a disregarded entity, your W-9 will still closely resemble a sole proprietor\u2019s setup.<\/p>\n\n\n\n Form Used:<\/strong> Federal W-9<\/p>\n\n\n\n Official Source:<\/strong>https:\/\/comptroller.texas.gov<\/a><\/p>\n\n\n\n Texas is a common choice for freelancers because it does not tax personal income and offers a business-friendly environment.<\/p>\n\n\n\n No personal income tax, but certain businesses may be subject to franchise tax.<\/p>\n\n\n\n Your W-9 remains a federal document regardless of your LLC status in Texas. The main consideration is whether your business crosses thresholds that trigger franchise tax.<\/p>\n\n\n\n From a W-9 perspective:<\/p>\n\n\n\n The state itself does not alter how the form is completed.<\/p>\n\n\n\n You can use KDAN PDF to fill out, sign, and send your W-9 digitally without printing, which helps keep your business documents organized and easy to update when your structure changes.<\/p>\n\n\n\n Your business structure directly affects how you complete your W-9, especially when deciding between an SSN and an EIN. Even after forming an LLC, many freelancers are still treated as sole proprietors for tax purposes, which means the form may not change as much as expected.<\/p>\n\n\n\n As your setup evolves, keeping your forms accurate becomes essential, and you can use KDAN PDF to manage, sign, and send your W-9 documents digitally while staying aligned with your current business structure.<\/p>\n\n\n\n Yes, in most cases, you should update your W-9 if your business structure or tax classification changes. This ensures your clients have the correct information for reporting.<\/p> <\/div> If your LLC is a single-member LLC taxed as a disregarded entity, you may still use your SSN. If your LLC is taxed as a corporation or partnership, you will typically use an EIN.<\/p> <\/div> No. The IRS determines which tax ID you use based on your business classification. States influence registration and taxes, but do not control W-9 requirements.<\/p> <\/div> <\/div>\n\n\n\n<\/span>What Is Form W-9?<\/strong><\/span><\/h2>\n\n\n\n
