New to this... Is it fairly safe to fill out and turn in the w9 form to all the different MSPs? I'm always a little hesitant because there's personal information. I'm assuming al the MSPs are legit and vetted for. Am I correct in assuming this? Also, do you guys just email it back as an attachment? Doesn't seem super secure to me. What have you guys done?

Are you sending in the W9 before a job pops up you are interested in? There is one solution to use a TaxID. They are created by the IRS and this number can be used in place of your Social Security Number. You can get one in Minutes. I have one that I use for Mystery Shopping and on line sales companies like Ebay and Mercari.

Yes the form is safe to send to the companies you are secret shopping for. Otherwise you will not get paid. Sending the attachment is safe. However, i wouldn’t do it from public Wi-Fi.
