What Happens If You Don’t Report Interest Income?

Ignoring that little 1099-INT sitting in your inbox? Thinking, “Surely the IRS won’t notice a few dollars in interest income?” Think again. Failing to report interest income can trigger a cascade of unwanted consequences, ranging from annoying notices to hefty penalties and even, in extreme cases, legal action. The bottom line is that the IRS receives a copy of every 1099-INT issued, so they will know about your interest income, whether you tell them or not.

The Immediate Repercussions of Non-Reporting

Let’s break down what happens when you decide to play hide-and-seek with your interest income.

CP2000 Notice: This is the IRS’s polite (but firm) way of saying, “We noticed a discrepancy.” A CP2000 notice arrives when the income reported by third parties (like banks) doesn’t match what you reported on your tax return. It’s not an audit, but it requires your attention. The notice will propose changes to your tax liability, including additional tax due, penalties, and interest.
Additional Tax Liability: The most obvious consequence is the added tax you’ll owe on the unreported interest income. This is calculated based on your tax bracket, so the higher your income, the more you’ll pay.
Penalties, Penalties, Penalties: This is where things get painful. The IRS can impose various penalties, including the accuracy-related penalty (typically 20% of the underpayment) and the failure-to-pay penalty (0.5% of the unpaid taxes for each month or part of a month the taxes remain unpaid, up to a maximum of 25%).
Accrued Interest: On top of the penalties, the IRS will charge interest on the unpaid tax liability from the original due date of your return until the date you pay. This interest rate fluctuates, but it adds up quickly.

The Long-Term Risks

While a CP2000 notice and some penalties might seem like a slap on the wrist, consistently failing to report interest income can lead to more serious issues.

Increased Audit Risk: Non-reporting raises a red flag, making you more likely to be selected for a full audit. An audit involves a more thorough examination of your financial records and can be a time-consuming and stressful process.
Statute of Limitations Extension: Generally, the IRS has three years from the date you filed your return to assess additional tax. However, if you omit a substantial amount of income (generally, more than 25% of the gross income reported on your return), the statute of limitations extends to six years. In cases of fraud, there is no statute of limitations.
Criminal Charges (in severe cases): While rare for simple non-reporting of interest income, intentional and large-scale tax evasion can lead to criminal charges, including fines and even imprisonment. This is usually reserved for cases involving deliberate attempts to conceal income or defraud the government.

How to Avoid the Pitfalls

The best way to avoid these issues is simple: report all your interest income accurately and on time.

Keep Accurate Records: Maintain records of all 1099-INT forms you receive.
Double-Check Your Return: Before filing, meticulously review your tax return to ensure all income is reported correctly.
Use Tax Software or a Professional: Tax software can help you navigate the complexities of tax laws and ensure accurate reporting. A tax professional can provide personalized advice and assistance.
Amend Your Return if Necessary: If you discover you made a mistake, file an amended tax return (Form 1040-X) as soon as possible. This shows the IRS you’re taking steps to correct the error and can potentially reduce penalties.

Ignoring interest income is a gamble with potentially costly consequences. Honesty and accuracy are always the best policies when it comes to your taxes.
