In this concise monologue, Mark Kohler breaks down the financial consequences of owing $10,000 in federal taxes. He explains the three primary cost components the IRS adds to an unpaid tax bill: the failure‑to‑file penalty (5% per month of the owed amount), the failure‑to‑pay penalty (0.5% per month when an extension is filed), and the federal interest rate (approximately 7% annually, or about 0.5% per month). Using a step‑by‑step example, Kohler shows that a $10,000 liability translates to roughly $50 per month in failure‑to‑pay penalties and $58 per month in interest, totaling about $108 per month. If the taxpayer waits until July to pay, they incur four months of these charges, resulting in an extra $450‑$500 beyond the original tax bill. The overall message is a cautionary illustration of how quickly penalties and interest can inflate a tax debt.

You don't even know what you owe and you're scared to death. But the worst penalty of all, failure to file. Failure to file is 5% a month of what you owed. Not good. But if you file an extension, the IRS is like, all right, at least we know you're in the system. We know you're not trying to hide from us. You filed an extension. We're going to wait for that return. You have until October. It's only a penalty for failure to pay because you bought time. That penalty is 0.5% per month. Much more digestible. And then interest. The federal rate last year was 7%. I think it's about the same this year. So what does that mean? If you owe the IRS $10,000, you owe them approximately $50 a month. That's the penalty until you file and pay. And the interest is approximately half a percent per month because it's 7% divided by 12, blah, blah, blah. So you would owe about $58 a month in interest. So for $108 a month or part thereof, that's what you owe on a $10,000 bill. So if you pay in July, then you've got to pay for your April month, part thereof, May, June and July. That's 4. So I would have to pay $200 in penalties in July and $225 approximately in interest. So you're out about $450 to $500. That's the damage.
