First of all, and obviously, you have to report all of your income regardless of whether or not a tax reporting statement is received.
Next, are you filing an 1120 for a C corporation? Is the C corporation invoicing clients?
Finally, if your own name and tax ID number (e.g., social security number) appears on the 1099, you need to report it on your individual income tax return or there will be a mismatch (either that or you can report the income on your return as nominee for the C corporation).
