Every year, thousands of taxpayers miss the filing deadline. Some are overwhelmed by paperwork, some are waiting on a missing form, and some simply can’t afford to pay. Whatever the reason, IRS penalties for late filing can turn a manageable tax bill into a much larger one.
The good news is that these penalties are largely avoidable, and even when they’ve already been charged, you often have options. At TJ Marshall Tax & Accounting in Marietta, GA, we help individuals and business owners stay compliant and resolve penalty problems. This guide explains how the penalties work, what they cost, and what you can do about them.
Why the IRS Charges Late Filing Penalties
The IRS runs on a self-reporting system. You calculate what you owe, file a return, and pay by the deadline. When you miss that deadline, the IRS charges penalties and interest to encourage timely compliance and to compensate the government for the delay.
For most individuals, the tax filing deadline is April 15 (or the next business day if it falls on a weekend or holiday). Business deadlines vary by entity type, so it’s worth confirming your specific dates every year.
The Two Main IRS Penalties: Failure to File vs. Failure to Pay
Many people assume there’s a single “late penalty.” There are actually two separate penalties, and they can stack on top of each other.
1. Failure-to-File Penalty
This applies when you don’t submit your return by the due date, including extensions.
- The rate: 5% of your unpaid taxes for each month (or part of a month) your return is late.
- The cap: 25% of your unpaid tax balance.
- The trap: Even one day late counts as a full month.
For example, if you owe $8,000 and file three months late, the failure-to-file penalty could reach roughly $1,200 before any other charges.
2. Failure-to-Pay Penalty
This applies when you file but don’t pay the full amount you owe by the deadline.
- The rate: 0.5% of your unpaid taxes for each month (or part of a month) the balance remains unpaid.
- The cap: 25% of your unpaid tax.
The failure-to-pay penalty is smaller, but it keeps accruing until the balance is paid in full.
How the Two Penalties Combine
In any month both penalties apply, the failure-to-file penalty is reduced by the failure-to-pay amount. That means the combined rate is 5% per month (4.5% for failure to file plus 0.5% for failure to pay), for up to five months. After that, the failure-to-file penalty stops growing, but the failure-to-pay penalty continues. The two together can reach up to 47.5% of your unpaid tax.
This is why filing on time matters even if you can’t pay. Filing alone cuts your monthly penalty dramatically, from 5% to 0.5%.
Minimum Penalty for Returns More Than 60 Days Late
If you file more than 60 days after the due date (including extensions), the IRS applies a minimum penalty. It is either a fixed dollar amount, which is adjusted for inflation each year, or 100% of the tax you owe, whichever is smaller. Check the IRS site or ask your tax professional for the current figure, because it changes.
Interest on Unpaid Taxes
On top of penalties, the IRS charges interest on any unpaid balance. Interest:
- Starts accruing from the original due date
- Compounds daily
- Is based on the federal short-term rate plus 3 percentage points
- Is adjusted quarterly, so it can rise or fall
- Applies to unpaid penalties, too
Unlike penalties, interest generally can’t be waived, so the longer a balance sits, the more it costs.
Other Late Filing Penalties That Can Apply
Individual income tax returns aren’t the only filings with penalties.
Business returns. Partnerships and S corporations that file late can face a penalty calculated per partner or shareholder, per month, for up to 12 months. For a business with several owners, this adds up quickly.
Information returns. Late or incorrect Forms W-2 and 1099 carry their own tiered penalties based on how late you correct or file them. If you have employees or contractors in the Marietta area, this is an easy item to overlook.
Fraudulent failure to file. If the IRS determines that a failure to file was fraudulent, the penalty jumps to 15% per month, up to a 75% maximum. That is a serious category, and it’s different from simply being disorganized or late.
Payroll and estimated taxes. Missed estimated payments or payroll deposits can trigger separate penalties, even if your annual return is filed on time.
Do You Owe a Penalty If You’re Due a Refund?
No. The failure-to-file and failure-to-pay penalties are calculated on the tax you owe. If you’re owed a refund, there’s generally no penalty for filing late.
However, there’s a catch. You usually have three years from the original due date to claim a refund. After that, the money becomes the government’s. So if you have unfiled returns from past years and think you might be owed money, don’t wait.
How to Avoid IRS Penalties for Late Filing
Avoiding penalties comes down to a few habits and decisions.
File a Tax Extension
If you can’t finish your return by the deadline, file Form 4868 for individuals before the due date. An extension gives you extra time to file, typically six months, but it does not give you extra time to pay.
To avoid the failure-to-pay penalty, estimate what you owe and send that payment by the original deadline. Even a good-faith estimate that’s reasonably close can protect you from the bulk of the penalties.
Heads up: the extended deadline for most individual filers falls on October 15, so if you’re on extension this year, the date is right around the corner.
File Even If You Can’t Pay
This is the most important rule. Filing on time, even with no payment, cuts your monthly penalty from 5% to 0.5%. Many people avoid filing because they’re afraid of the bill. In reality, that fear often makes the bill bigger.
Set Up a Payment Plan
If you can’t pay in full, the IRS offers installment agreements. While an approved plan is in effect, the failure-to-pay penalty rate can be reduced, provided your return was filed on time. Short-term payment extensions may also be available. A tax professional can help you choose the right option and avoid defaults.
Organize Your Documents Early
A lot of late filings come down to missing paperwork. Create a simple checklist and start gathering documents in January:
- W-2s and 1099s
- Mortgage interest and property tax statements
- Business income and expense records
- Retirement and investment account statements
- Receipts for deductions and credits
If something hasn’t arrived by mid-February, follow up with the issuer. If a form never shows up, a tax professional can often help you file using reasonable estimates and the correct IRS procedures.
Use Calendar Reminders and Estimated Tax Payments
Self-employed individuals, freelancers, and landlords often need to make quarterly estimated tax payments. Set recurring reminders for each due date so nothing slips through. Missing these doesn’t just risk penalties; it can also create a large lump-sum bill at year-end.
Work With a Local Tax Professional
A qualified accountant does more than prepare forms. They track deadlines, spot potential issues early, and plan ahead so you’re never scrambling. If you’re searching for a tax accountant in Marietta, GA, our team at TJ Marshall Tax & Accounting offers year-round support, not just a once-a-year filing.
What to Do If You’ve Already Been Charged a Penalty
Getting a penalty notice doesn’t mean you’re out of options. The IRS offers several forms of relief.
First-Time Penalty Abatement
If you have a clean compliance history, you may qualify for First-Time Abatement. Generally, you need to meet these conditions:
- You filed all required returns (or have valid extensions)
- You had no penalties in the previous three tax years, or any earlier penalties were removed for reasons other than first-time abatement
- You’ve paid, or arranged to pay, the tax due
If you qualify, the IRS can remove failure-to-file, failure-to-pay, and failure-to-deposit penalties. It’s one of the most overlooked tools available to taxpayers.
Reasonable Cause Relief
The IRS may waive penalties if you can show you acted responsibly but couldn’t comply because of circumstances outside your control. Examples can include:
- A serious illness or hospitalization
- A death in the immediate family
- A natural disaster or fire
- Inability to obtain records through no fault of your own
- Incorrect written advice from the IRS
You’ll need documentation, and a clear, honest explanation matters. Poor preparation is the most common reason these requests fail.
Disaster Relief Postponements
When the IRS announces disaster-related relief for a specific area, filing and payment deadlines may be postponed automatically for taxpayers in that region. It’s worth checking if a declared disaster affected Georgia in the relevant period.
How to Request Penalty Relief
You can request relief by calling the number on your notice, responding in writing, or filing Form 843 (Claim for Refund and Request for Abatement). Always respond before the deadline listed on the notice, and keep copies of everything you send.
Don’t Forget Georgia State Taxes
If you live or run a business in Marietta, you also have obligations to the Georgia Department of Revenue. Georgia has its own late filing and late payment penalties and interest, separate from the IRS. A federal extension doesn’t automatically cover every state requirement, so confirm your Georgia deadlines and payment rules, or have your accountant do it for you.
Common Mistakes That Lead to Penalties
Here are the errors we see most often with Cobb County and metro Atlanta clients:
- Assuming an extension extends payment. It doesn’t.
- Skipping filing because of a balance owed. Filing late costs far more than filing and paying slowly.
- Ignoring IRS letters. Notices have strict response windows, and silence can lead to bigger problems.
- Missing estimated payments. This is especially common for new business owners.
- Not filing at all. If you don’t file, the IRS can prepare a substitute return for you, which usually doesn’t include all the deductions you’re entitled to.
- Waiting too long to get help. The earlier you address a problem, the more options you typically have.

Frequently Asked Questions
What is the penalty for filing taxes late?
The failure-to-file penalty is 5% of your unpaid tax per month, up to 25%. If you also don’t pay, an additional 0.5% per month applies.
Is it better to file late or not file at all?
Always file, even if late. Not filing leaves the full penalty clock running and can lead to a substitute return prepared by the IRS.
Can IRS late filing penalties be removed?
Often, yes. First-Time Abatement and reasonable cause relief are the two most common routes.
Does a tax extension stop penalties?
It stops the failure-to-file penalty if you file by the extended deadline, but you still need to pay what you owe by the original due date to avoid failure-to-pay penalties.
How long do I have to file a return and claim a refund?
Generally, three years from the original due date.
