Running a small business comes with many responsibilities, including staying compliant with tax regulations. The IRS imposes penalties when businesses fail to meet filing, reporting, or payment obligations. These penalties can be costly, affecting cash flow and financial stability. Understanding the most common IRS penalties allows business owners to take proactive steps to avoid them. This guide explains the 15 IRS penalties every business owner should know and how professional guidance from Nexus United Inc can help mitigate risks and ensure compliance.
Top IRS Penalties Every Business Owner Should Know
1. Failure to File Penalty
One of the most common IRS penalties is imposed when a business fails to file a tax return by the due date.
Penalty: 5% of the unpaid tax per month, up to 25%
Why it happens: Late filing or missing returns
Filing on time or requesting an extension can help avoid this penalty.
2. Failure to Pay Penalty
If your business owes taxes and does not pay by the due date, the IRS may impose a failure-to-pay penalty.
Penalty: 0.5% of unpaid tax per month, up to 25%
Tip: Making estimated quarterly tax payments reduces this risk.
3. Underpayment of Estimated Tax Penalty
Businesses that do not pay enough estimated taxes throughout the year may face penalties.
Who it affects: Sole proprietors, LLCs, S-Corp shareholders, and contractors
Solution: Learn how to estimate quarterly taxes and make timely payments.
4. Payroll Tax Penalties
Employers are responsible for withholding, reporting, and remitting payroll taxes. Errors can result in severe penalties.
Penalty types: Late deposits, underpayment, misclassification of employees
IRS form references: Form 941, Form 940, W-2, 1099-NEC
Accurate payroll management is essential to avoid these penalties.
5. Failure to Deposit Penalty
This applies when payroll or employment taxes are not deposited on time.
Penalty: 2% to 15% of the underpayment depending on the delay
Tip: Use EFTPS or other IRS-approved deposit methods for timely payments.
6. Accuracy-Related Penalties
Errors in reporting income, deductions, or credits can trigger accuracy-related penalties.
Penalty: 20% of the underpayment due to negligence or substantial understatement
Common triggers: Overstated deductions, misreported income, incorrect calculations
Proper bookkeeping and review help prevent these errors.
7. Fraud Penalties
Deliberate misrepresentation or fraud carries some of the highest penalties.
Penalty: 75% of the underpayment attributable to fraud
Tip: Maintain transparent, accurate records and avoid any misrepresentation.
8. Information Return Penalties
Failing to file correct information returns such as W-2s or 1099s can result in penalties.
Penalty: $50 to $280 per form, depending on delay
Tip: Ensure all employee and contractor forms are submitted correctly and on time.
9. Failure to Provide Correct Payee Statements
Providing inaccurate 1099s or W-2s to employees or contractors triggers penalties.
Penalty: Similar to information return penalties
Solution: Review forms carefully before submission.
10. Late Filing of Forms 940 or 941
Employers who file Forms 940 (FUTA) or 941 (quarterly payroll) late may incur penalties.
Penalty: Varies based on number of days late
Tip: Automate filing reminders or use a payroll service to avoid late submissions.
11. Failure to Deposit Excise Taxes
Businesses that owe excise taxes must deposit them on time.
Penalty: 10% to 100% of the tax depending on the delay
Example: Fuel excise taxes, environmental taxes, or luxury taxes
12. Negligence Penalty
Failure to exercise reasonable care in preparing returns can result in negligence penalties.
Penalty: 20% of the underpayment
How to avoid: Accurate bookkeeping, professional review, and proper documentation.
13. Late Payment of Corporate Income Tax
Corporations that fail to pay federal income tax on time may face penalties.
Penalty: 0.5% per month of unpaid tax
Tip: Corporations should make quarterly estimated tax payments to avoid this.
14. Penalties for Misclassification of Workers
Misclassifying employees as independent contractors to avoid payroll taxes is risky.
Penalty: Unpaid payroll taxes, plus interest and fines
Tip: Review IRS guidelines on employee vs. contractor classification.
15. Penalties for Failure to Maintain Records
The IRS requires businesses to maintain sufficient records to support reported income, deductions, and credits.
