Penalties and IRS Notices
Maria came in holding an envelope like it might bite her. She hadn’t opened it yet. It said IRS on the front. It had been sitting on her kitchen counter for nine days.
“I’m scared to open it,” she said.
Ralph opened it. He read it. He looked up.
“It’s a CP503,” he said. “Second notice on a balance from last year. You owe $1,240. That’s it. No audit. No investigation. Just a bill.”
Maria let out a long breath. “Nine days I’ve been scared of that thing.”
Most IRS letters are not audits. Most are not criminal matters. Most are exactly what Maria’s was: a bill, a question, or a mismatch that the IRS wants you to look at. The fear is almost always bigger than the actual problem. Your job is to be the person who opens the letter, reads it calmly, and tells the client what’s actually happening.
There are many IRS penalties but two show up constantly with your clients. Know both of them cold.
Failure to File Penalty. If a client doesn’t file their return by the deadline, the IRS charges 5% of the unpaid tax for every month (or partial month) the return is late. This stacks up to a maximum of 25%. On a $4,000 tax bill, that’s up to $1,000 in penalties just for not filing — on top of whatever interest accrues.
Failure to Pay Penalty. If a client files but doesn’t pay what they owe, the penalty is just 0.5% per month. Much smaller. This is why the rule is so important: always file on time even if you can’t pay. The filing penalty is ten times larger than the payment penalty. File the return. Set up a payment plan. But file.
Every IRS notice has a number. That number tells you exactly what the letter is about. The most common ones:
| Notice | What It Means | Action Needed |
|---|---|---|
| CP2000 | Income on IRS records doesn’t match the return | Respond within 60 days — agree or dispute |
| CP501 | First balance due reminder | Pay or call to set up a payment plan |
| CP503 | Second balance due reminder | Pay now or expect escalation |
| CP504 | Intent to levy — urgent | Respond immediately |
| LT11 | Final notice before levy action | Respond immediately — get professional help |
An audit is a formal IRS examination of a specific tax return. The IRS is asking to see documentation for items on the return. Audits are much less common than people fear — the IRS audits less than 1% of individual returns. For simple W-2 returns with no unusual items, the chance of an audit is extremely low.
What triggers audits: large deductions relative to income, big round numbers that look estimated, business losses that repeat year after year, home office deductions, unusually high charitable contributions, and certain high-income returns. We cover this in more detail in the Ethics and Due Diligence module.
That’s not an audit. It’s a notice that the income on his return doesn’t match a 1099 the IRS received. The IRS is asking about it, not auditing his entire return. You respond to the CP2000, explain the income, pay any difference, and the matter closes. The fear was thirty times bigger than the actual problem.
