Vendor Names, W-9s, and 1099s
Our buyers look for the business name of a vendor when they go to create a purchase order, so we put the name from the second line of the W-9 on the header of the vendor record (when it is supplied).
When we filed our 1099s, we received notice from the IRS that the many Tax IDs were incorrect, since they did not match the "tax return name". We've been told by the IRS that there is a fine for a subsequent filing of the same incorrect name/Tax ID number.
