My business partner and I operate a digital marketing agency together. Before that we had separate Upwork accounts doing our own freelance work. Now that we're under a business together, we report all our earnings through the company - one single EIN. He is currently using our S-Corp's EIN for his Upwork account. Can I also attach the same EIN to my Upwork account? We still withdraw to separate bank accounts, but just report our earnings through the same business/EIN.
Unfortunately, we aren't able to specifically advise users on what information they need to enter to their tax forms and you may want to consult with a tax professional regarding this.
Generally, if a user has an individual Freelancer account, then they may enter their personal SSN in their W-9 form.
If a user is a part of an Upwork agency, receiving payment through that agency, they may use the company's EIN on the agency account.
Note that if SSN / EIN name does not match the name on the Upwork account, then this may cause a mismatch during our IRS reporting.
