Either you report that income on your taxes via 1099 and then the IRS goes to the company that created the 1099 and asks them why the 1099 doesn't have a TIN or you don't report the income on your taxes and the IRS finds out and fines you for tax evasion.

Edit: I see that you are Canadian. Unfortunately for your aspirations of tax evasion, the US and Canada have a very friendly information sharing relationship.
