Forgetting to file a 1099 on your taxes can lead to IRS penalties, interest on underpaid taxes, and potential audit risks, as the IRS receives copies of 1099s directly from payers. To resolve this, you should file an amended return (Form 1040-X) as soon as possible to minimize additional costs and penalties.
