IRS Tax Penalties: Individuals & Businesses

At Fresh Start Financial, we believe understanding tax penalties is an important part of maintaining financial health and staying compliant with federal tax laws. Missing a filing deadline, failing to pay taxes on time, or neglecting required business tax filings can result in significant penalties and interest.

Below is an overview of common federal IRS penalties for individuals, corporations, partnerships, S corporations, and employers.

For the most current information, visit the official IRS Payments and Penalties page.

Note: Penalty amounts may vary based on the tax year, filing deadline, amount owed, type of return, and circumstances of the taxpayer. The amounts below are general guidelines and should be verified against current IRS guidance.

Individual and C Corporation Income Tax Penalties

The IRS may impose penalties when an individual or corporation fails to file a required income tax return or pay taxes by the applicable deadline.

Failure-to-File Penalty

• Generally, 5% of unpaid tax for each month or partial month the return is late.

• The penalty generally reaches a maximum of 25% of the unpaid tax.

• For returns due in 2026, the minimum penalty for a return more than 60 days late is generally $525 or 100% of the tax due, whichever is less.

Failure-to-Pay Penalty

• Generally, 0.5% of unpaid tax for each month or partial month the tax remains unpaid.

• The penalty generally reaches a maximum of 25% of the unpaid tax.

• Qualifying taxpayers with approved installment agreements may receive a reduced rate in certain circumstances.

When both filing and payment penalties apply, the IRS generally reduces the failure-to-file penalty for the same month by the failure-to-pay penalty.

An extension generally provides additional time to file, not additional time to pay taxes owed.

S Corporation and Partnership Late-Filing Penalties

S corporations and partnerships may face penalties for filing their federal income tax returns late, even when the entity does not owe federal income tax directly.

For returns due in 2026, the general late-filing penalty is:

• S corporations — Form 1120-S: $255 per shareholder, per month or partial month, for up to 12 months.

• Partnerships — Form 1065: $255 per partner, per month or partial month, for up to 12 months.

Example: A partnership with three partners that files six months late could face a penalty of $4,590, calculated as $255 × 3 partners × 6 months.

The final penalty depends on the applicable filing year, number of partners or shareholders, length of delay, and whether penalty relief is available. Certain exceptions and relief provisions may apply.

Forms W-2 and 1099 Information-Return Penalties

Businesses that fail to file correct information returns or provide required statements to recipients may face penalties for each affected form.

For information returns due in calendar year 2026, general penalty tiers include:

• $60 per return: Corrected within 30 days after the applicable deadline.

• $130 per return: Corrected more than 30 days late but by August 1.

• $340 per return: Filed after August 1 or not filed.

• $680 per return: Intentional disregard of applicable filing or furnishing requirements.

Different annual maximums may apply to small businesses and other filers. Intentional-disregard penalties generally do not have the same maximum limits.

Penalties may apply separately to the information return filed with the IRS and the statement required to be furnished to the recipient.

Payroll Tax Penalties

Employers must deposit federal payroll taxes according to their assigned deposit schedule. Missing a deposit deadline can result in the following penalties:

• 1–5 calendar days late: 2% of the unpaid deposit.

• 6–15 calendar days late: 5% of the unpaid deposit.

• 16 or more calendar days late: 10% of the unpaid deposit.

• Certain payments made directly to the IRS instead of deposited properly: 10%.

• Certain deposits made more than 10 days after the first applicable IRS notice or demand: 15%.

These penalties generally apply to the affected deposit amount. The applicable rules, exceptions, and relief provisions depend on the circumstances.

Trust Fund Recovery Penalty

The Trust Fund Recovery Penalty is a serious penalty that may apply when a responsible person willfully fails to collect, account for, or pay over certain employment taxes withheld from employees.

The penalty may equal 100% of the unpaid trust fund taxes. It may be assessed personally against responsible individuals, including certain business owners, officers, and other persons, even if the business is incorporated.

Estimated Tax Underpayment Penalties

Individuals, self-employed taxpayers, and corporations may incur penalties when they fail to make sufficient estimated tax payments throughout the year.

The IRS generally calculates the penalty based on the amount underpaid, the length of the underpayment period, and the applicable interest rates.

For many individual taxpayers, the penalty may be avoided if the balance due after withholding and refundable credits is less than $1,000 or if the taxpayer satisfies applicable safe-harbor requirements. Different rules apply to corporations and certain other taxpayers.

Other Common IRS Penalties

Other federal tax penalties may apply depending on the type of filing error or compliance failure.

• Negligence or substantial understatement of income tax: Generally, 20% of the applicable underpayment.

• Civil fraud penalty: Generally, 75% of the portion of an underpayment attributable to fraud.

• Late payment of assessed taxes: Applicable failure-to-pay penalties and interest may continue to accrue.

• Failure to file required information returns: Per-form penalties may apply.

• Failure to comply with other federal tax reporting requirements: Additional penalties may apply under the specific law governing the requirement.

These penalties are subject to specific legal requirements and exceptions. They are not automatically imposed whenever a return contains an error.

Important Things to Know About IRS Penalties

Tax extensions do not extend payment deadlines. Taxpayers generally must pay their estimated tax liability by the original due date to minimize late-payment penalties and interest.

Interest may accrue separately. The IRS generally charges interest on unpaid taxes and certain penalties. Rates may change quarterly, and interest generally compounds daily.

Penalty relief may be available. Taxpayers who qualify may request relief based on reasonable cause or other applicable IRS provisions. Eligibility depends on the specific penalty and circumstances.

State penalties are separate. The amounts discussed here concern federal IRS penalties. Florida and other states may impose separate penalties for corporate income tax, sales tax, payroll tax, annual reports, and other state filing obligations.
