Learn how to complete IRS form W9 for your Solo 401k Trust

If your Solo 401k trust purchases an investment such as real estate, you may be required to complete form W9.

Form W-9 is used by both individuals and entities to provide their taxpayer identification number (TIN or EIN) to entities who will pay them during the tax year.

Entities will use form W-9 for accounting purposes, but generally don't send a copy of the form to the IRS. The information on form W9 is then used to prepare IRS form 1099-MISC at the end of the year to document payments.

If your Solo 401k trust completes this form, and receives form 1099-MISC, it doesn't mean you have to pay any taxes, but you may still need to complete a tax return for your entity.  The tax return would be informational only as your original EIN (employer identification number) for your Solo 401k Trust is connected to and owned by a tax-deferred or tax-exempt entity (your retirement account).
