Filling Out a W-9 Form

Filling out a W-9 form will require individuals to provide their legal name, official company name and determine which tax classification the entity falls into.

C-Corporation tax status (C)
A C-Corp is a limited liability company that elects to be taxed as a corporation by the IRS. This is the option of being taxed as a C corporation. Whether there is only one member or many, this status can be assigned to the LLC.
- If your LLC is taxed as a C corporation, please check the box on line 3 of IRS form 8832.
- On the left side of the screen, click on “Completed Forms” and then “Form 941.” To the right of the LLC box, type “C.”

- TIN- Enter the EIN, employer’s identification number
S corporation tax status (S)

An LLC that wants to be classed as an S corporation by the IRS must fill out Form 2553.
This is a paperwork choice to be taxed as an S corporation. Whether there's a single member or many, this status may be granted.
- If your LLC is taxed as a C corporation, check the box on line 3 of Form 941 and write in "S" to the right of the LLC box.
- Name- Enter the legal name of the LLC, as it appears on IRS documentation on line 1 of the form.

Partnership tax status (P)
All LLCs with more than one member that has not chosen to be treated as an S or C corporation for tax purposes will be treated as a partnership by default.

- Name- Enter the legal name of the LLC, as it appears on IRS documentation on line 1 of the form.

Single-member LLC (disregarded entity)
The IRS does not consider a single-member LLC to be a separate entity from its owner. In this situation, single members must fill out their Form W-9.
- Unless the single-member LLC has chosen to be classified as a C or S corporation, it should enter its owner's tax classification on line 3.
- Name- Enter the legal name of the LLC’s owner, as it appears on official documentation on line 1 of the form.

If you are a Foreign General Partnership (GP) or Foreign Limited Liability Partnership (LLP), check the fourth box on the W-9. Fill out lines A – D as instructed.
Finally, if you are a Foreign Limited Liability Company (LLC), check the fourth box on the W-9. Fill out lines A – D as instructed.
