It is common to report an incorrect Tax Identification Number (TIN) or name when filing 1099 forms with the IRS. Sometimes it could be a typo, or it could be because the vendor provides their business name with their social security number (SSN), or vice versa. To prevent the IRS from issuing penalties for inaccurate reporting, it is recommended that you verify the accuracy of the recipient's Tax Identification Number (TIN) before filing 1099 forms.
