IRS Penalties Explained: What Taxpayers Need to Know Before the Balance Gets Bigger

Receiving a letter from the IRS showing that you owe money can be stressful. What many taxpayers don’t realize is that the original tax balance may only be part of the problem.

Penalties and interest can continue increasing the amount you owe.

The IRS can assess penalties when taxpayers fail to file returns on time, fail to pay taxes when due, file inaccurate returns, fail to make required estimated tax payments, or fail to properly file certain information returns. (IRS)

Understanding what you’re being charged — and responding early — can make a significant difference.

Common IRS Penalties Taxpayers Should Know About

1. Failure-to-File Penalty

One of the most important rules to understand is this:

Not being able to pay your tax bill is generally not a good reason to avoid filing your return.

The failure-to-file penalty generally applies when a required tax return isn’t filed by its due date.

The IRS states that the failure-to-file penalty is generally 5% of the unpaid tax for each month or part of a month that the return is late, up to 25%. When both the failure-to-file and failure-to-pay penalties apply during the same month, special rules coordinate the two penalties. (IRS)

For returns required to be filed in 2026, a return more than 60 days late may also be subject to a minimum failure-to-file penalty of the lesser of $525 or 100% of the tax required to be shown on the return. (IRS)

The takeaway?

File the return even if you cannot afford to pay the entire balance.

2. Failure-to-Pay Penalty

Filing the return doesn’t eliminate the consequences of an unpaid balance.

The IRS generally assesses a failure-to-pay penalty of 0.5% of the unpaid tax for each month or part of a month the balance remains unpaid, up to 25%. (IRS)

If an IRS payment plan is in effect and certain requirements are met, the failure-to-pay penalty rate may be reduced to 0.25% per month. (IRS)

This is why ignoring an IRS balance usually makes the situation more expensive rather than making it disappear.

3. Accuracy-Related Penalties

Sometimes the return is filed and the tax is paid — but the IRS later determines that the return wasn’t accurate.

An accuracy-related penalty can apply when a taxpayer underpays tax because of issues such as negligence, disregarding tax rules, failing to report income, or substantially understating income tax.

The accuracy-related penalty is generally 20% of the portion of the underpayment attributable to the applicable issue. (IRS)

One example the IRS specifically identifies is failing to report income that was reported to the IRS on an information return such as a Form 1099. (IRS)

This is one reason taxpayers should make sure their income records, 1099s, business books, deductions and tax return all tell the same financial story.

4. Estimated Tax Penalties

Self-employed individuals, independent contractors and business owners need to pay particular attention to estimated taxes.

Unlike traditional employees, who usually have income taxes withheld from each paycheck, self-employed taxpayers may need to make estimated tax payments throughout the year.

If you don’t pay enough tax during the year — or don’t make required payments on time — an underpayment of estimated tax penalty may apply.

The IRS calculates the penalty based on factors including:

• The amount of the underpayment

• How long the amount remained underpaid

• Applicable quarterly underpayment rates (IRS)

This is why tax planning shouldn’t begin when it’s time to file the return.

For business owners and 1099 earners, tax planning should happen throughout the year.

5. Information Return Penalties

Businesses have another area of exposure: information returns.

Penalties may apply when required information returns or payee statements aren’t filed correctly or on time.

That can include reporting obligations associated with payments to workers, contractors and other recipients.

For information returns due in 2026, IRS penalties can vary depending on how late the return is filed. The IRS currently lists penalties ranging from $60 per return for certain filings corrected within 30 days to $340 for certain returns filed after August 1 or not filed, with substantially higher penalties for intentional disregard. (IRS)

For a business with multiple required forms, those penalties can add up quickly.

Don’t Forget About Interest

Penalties aren’t necessarily the end of the calculation.

The IRS also charges interest on penalties in applicable situations, and interest can continue increasing the total balance until the liability is paid. (IRS)

That means waiting to address an IRS problem can turn a manageable balance into a much larger financial issue.

Can IRS Penalties Be Removed?

Sometimes.

Receiving a penalty notice does not automatically mean you should simply pay it without reviewing it.

The IRS offers several forms of penalty relief, depending on the circumstances.

One possibility is reasonable cause relief.

The IRS may consider removing or reducing certain penalties when a taxpayer can demonstrate that they exercised ordinary business care and prudence but were still unable to meet their tax obligation. Reasonable cause is evaluated based on the individual facts and circumstances. (IRS)

Depending on the penalty and circumstances, supporting documentation can be extremely important.

The IRS may consider factors such as:

• What happened

• When it happened

• How the circumstances prevented compliance

• What efforts the taxpayer made to comply

• How quickly the taxpayer corrected the issue

Supporting records may also be necessary. (IRS)

Important: Reasonable cause doesn’t apply to every type of penalty, including certain estimated-tax penalties. (IRS)

Received an IRS Penalty Notice? Don’t Ignore It.

If you’ve received an IRS notice, start by determining exactly what the IRS says happened.

The notice should identify the penalty, explain why it was assessed and provide instructions about what to do next. (IRS)

Before paying or responding, consider these questions:

1. Is the IRS information correct?

2. Was the underlying tax return filed correctly?

3. Were payments properly credited?

4. Is the penalty calculation accurate?

5. Were there circumstances that may support penalty relief?

6. Is there a deadline to dispute or respond to the notice?

IRS notices can contain important response deadlines. Don’t put the letter in a drawer and plan to deal with it later.

Can’t Pay the IRS in Full?

You may still have options.

The IRS encourages taxpayers who can’t pay the entire balance to pay what they can and consider available payment arrangements. An installment agreement may allow an eligible taxpayer to pay a balance over time and, in some situations, may reduce future penalties. (IRS)

The key is addressing the balance instead of ignoring it.

Prevention Is Usually Less Expensive Than Correction

Many tax problems can be reduced or avoided with better planning.

For individuals, that may mean reviewing withholding before the end of the year.

For self-employed taxpayers, it may mean calculating estimated tax payments instead of waiting until tax season.

For businesses, it can mean maintaining accurate bookkeeping, reconciling accounts, properly tracking contractor payments and reviewing financial records throughout the year.

Good bookkeeping isn’t just about knowing how much money your business made. It’s also part of good tax compliance.
