Yes, forgetting a 1099-INT will likely trigger an IRS notice or audit. Because financial institutions report this interest income directly to the IRS, their automated systems ({Link: Automated Underreporter (AUR) program https://cointracker.io/blog/will-the-irs-catch-a-missing-1099}) will identify the mismatch. You will likely receive a CP2000 notice requesting payment for the tax owed, plus interest and potential penalties.

How badly does a 1099 affect my taxes?

A 1099 significantly affects taxes because you're considered self-employed, meaning you pay both income tax and the full self-employment tax (15.3% for Social Security & Medicare), as there's no employer to split it with. This usually means setting aside 25-35% of your income, and you'll likely need to make quarterly estimated tax payments to avoid penalties, though business expense deductions can lower your taxable amount.
