Tax season is here, and one of the biggest mistakes taxpayers make is failing to file or pay their taxes on time. If you owe the IRS, missing the April 15, 2025 deadline could result in hefty penalties and interest charges that quickly add up.
In this guide, we’ll break down:
✅ The consequences of failing to file or pay your taxes
✅ How interest and penalties are calculated
✅ Steps to avoid IRS fines and reduce your tax burden

Failure to Pay: What Happens If You Don’t Pay Taxes on Time?
If you owe taxes and don’t pay by the due date, the IRS will start charging interest and penalties immediately.
1️⃣ Interest Charges on Unpaid Taxes
-
Interest begins accruing the day after the deadline unless you file for an extension.
-
The IRS updates interest rates quarterly, which are based on the federal short-term rate plus 3%.
-
Interest is compounded daily, meaning it grows every single day you don’t pay.
💡 Example:
If the interest rate is 7% and you owe $100, here’s how quickly the amount grows:
✔️ Day 1: $100 x 7% = $107
✔️ Day 2: $107 x 7% = $114.49
✔️ Day 3: … and so on until paid in full

2️⃣ Failure to Pay Penalty
-
There is a failure to pay penalty on top of interest charges.
-
The penalty is equal to ½ of 1% which equals to .05% applied to each month
💡 Example:
If you owe $1,000 and don’t pay:
-
April Penalty: $1,000 x 0.5% = $5 added
-
May Penalty: New balance + 0.5%
-
This continues until you hit 25% of the total owed
3️⃣ How to Reduce the Failure to Pay Penalty
📌 Set Up an IRS Payment Plan (Installment Agreement)
If you can’t pay the full amount, request a payment plan with the IRS.
✔️ This reduces the penalty from 0.5% to 0.25% per month
✔️ You still pay interest, but at a lower rate

Failure to File: What Happens If You Don’t File Taxes on Time?
Not filing your tax return is worse than not paying because the failure-to-file penalty is significantly higher.
1️⃣ Penalty for Late Tax Filing
-
The IRS charges 5% of the unpaid taxes per month, up to a maximum of 25%.
-
If your tax return is 6 months late, there is a minimum penalty of:
✔️ $510 or 100% of the tax owed (whichever is lower).
💡 Example:
If you owe $2,000 and don’t file:
✔️ Month 1 Penalty: $2,000 x 5% = $100 added
✔️ Month 2 Penalty: New balance + 5%
✔️ This continues until you reach 25% of your total tax bill
2️⃣ How to Avoid the Failure to File Penalty
📌 File for a Tax Extension (IRS Form 4868)
✔️ This gives you an extra 6 months to file (until October 15, 2025).
✔️ It does NOT extend your payment due date—you must estimate and pay any taxes owed by April 15.
