Avoiding IRS Penalties: The Most Common Mistakes and How to Fix Them

No one wants a letter from the IRS—especially if it includes a bill. But every year, millions of taxpayers end up with penalty charges for simple, avoidable mistakes.

Here’s how to avoid being one of them.

⏱ Penalty #1: Filing Late

Even if you can’t pay your taxes in full, always file on time. The IRS charges a steep penalty—5% of your unpaid balance per month—just for missing the deadline.

💸 Penalty #2: Underpayment

If you’re self-employed, own rental property, or have multiple income sources, you may need to pay quarterly estimated taxes. Miss those? You’ll owe penalties and interest.

❌ Penalty #3: Math or Reporting Errors

Simple mistakes like wrong totals, mismatched numbers, or missing forms can cause the IRS to flag your return—and charge a fee.

📨 What If You Get a Notice?

Don’t panic. Most notices are just asking for clarification or payment. But ignoring it is the worst thing you can do.

Respond promptly, and always contact a tax pro if you're unsure.
