I printed out the w-9 and signed it. Now what do I do?

Hi Mark! Who sent you a w-9?

I got it off the internet...

Does an MSP require a w-9? If so, then in their contract agreement you signed, it should indicate how and where they want you to send it. Like via email in a PDF file, or to a physical address. Also, contact them directly. Their phone number and email should also be listed in your iSS portal.

Hope this helps.
