Filing IRS Form 1120, the U.S. Corporation Income Tax Return, is a crucial part of corporate tax compliance for C corporations. However, this form is complex and mistakes are common, especially for businesses that are filing for the first time or those managing multiple returns. Incorrectly filed Form 1120 can result in delayed processing, penalties, or missed tax savings opportunities.
In this blog, we will explore the most common errors made when filing IRS Form 1120 and how businesses can avoid them. Additionally, we’ll discuss how working with experienced tax professionals, like PEAK Business Consultancy Services (PEAK BCS), can ensure accurate and timely filing.

1. Incorrectly Reporting Corporate Income
One of the most frequent mistakes when filing Form 1120 is failing to accurately report corporate income. This can happen if income is not properly categorized or if certain sources of income, such as investments, are omitted. The IRS requires that all taxable income, including sales revenue, interest, dividends, and gains, be accurately reported.
How to Avoid This Error: Ensure that all sources of income are accounted for, including any income from investments, foreign income, and capital gains. Double-check income statements, accounting records, and any other financial documents to confirm that all income has been included. For complex income sources, it is recommended to consult with a tax professional.
2. Misreporting Deductions
C Corporations are entitled to claim various deductions for business expenses such as operating costs, salaries, office supplies, and business travel. However, misreporting or incorrectly claiming deductions can lead to substantial errors in the tax return. Overstating deductions can raise red flags with the IRS, while underreporting them can result in paying more taxes than necessary.
How to Avoid This Error: Carefully review all deductions to ensure they meet IRS guidelines. Keep detailed records of business expenses, including receipts, invoices, and statements. Ensure that only legitimate business expenses are deducted, and consult IRS publications or a tax expert to confirm the correct treatment of complex deductions, like R&D expenses or depreciation.
3. Failure to Include All Required Schedules
Form 1120 requires various supporting schedules, such as Schedule C (for cost of goods sold), Schedule J (for tax computation), and Schedule K (for additional information). Failing to include the necessary schedules or submitting incomplete schedules is a common mistake that can delay processing or trigger audits.
How to Avoid This Error: Always ensure that all required schedules are attached to your Form 1120. Double-check the filing instructions to make sure no schedules have been overlooked, especially if your corporation has complex operations. It’s advisable to work with a tax professional to ensure all forms and schedules are correctly completed and filed on time.
4. Incorrectly Reporting Shareholder Information
Form 1120 requires accurate information about the corporation’s shareholders, including their names, addresses, and ownership percentage. Mistakes in reporting shareholder information can cause delays and errors in calculating dividends or distributions. Incorrect shareholder data can also trigger IRS inquiries or audits.
How to Avoid This Error: Verify that all shareholder details are correct and consistent with other corporate records, such as shareholder agreements and stock ledgers. Ensure that the ownership percentages match the official records and that all required information is included. If there are changes in ownership during the year, ensure these are properly reported on the return.
5. Failing to File Form 1120 on Time
Missing the filing deadline for Form 1120 is a common and costly mistake. C corporations are required to file their tax return by the 15th day of the fourth month following the close of their fiscal year (April 15th for calendar-year corporations). Failing to file on time results in penalties, interest charges, and in some cases, the disallowance of certain deductions.
How to Avoid This Error: Mark your calendar for the filing deadline and ensure all necessary information is ready well before the due date. If needed, file for an extension using IRS Form 7004. Extensions provide additional time to file, but they do not extend the time to pay any taxes owed, so be sure to make a payment if necessary to avoid late payment penalties.
6. Incorrect Depreciation and Amortization Calculations
Depreciation and amortization are essential for reducing taxable income, but incorrect calculations are a common error. This is particularly tricky when dealing with large fixed assets, multiple asset classes, or assets placed in service during the tax year. The IRS has specific rules on how businesses should calculate depreciation and amortization for various types of assets.
How to Avoid This Error: Use the IRS guidelines and proper accounting methods for depreciation, such as the Modified Accelerated Cost Recovery System (MACRS). Ensure that all assets are classified correctly and that depreciation or amortization is spread over the correct period. Consulting with an accountant or tax professional to apply the correct depreciation methods is advisable to avoid errors.
7. Misclassifying Income as Capital Gains
One significant mistake is incorrectly classifying income as capital gains when it should be considered regular income, or vice versa. This misclassification can lead to significant tax errors and penalties. For instance, ordinary income is taxed at higher rates than capital gains, so improperly reporting income can result in paying more taxes than required.
How to Avoid This Error: Ensure that the income is classified according to IRS rules. Capital gains arise from the sale of capital assets like property or investments, and they may be eligible for preferential tax rates. In contrast, regular income is subject to ordinary tax rates. Working with a tax professional can help properly classify different types of income on Form 1120.
8. Failure to Account for Foreign Income and Foreign Tax Credit
For corporations with international operations, failure to report foreign income and claim the foreign tax credit is a common and costly error. U.S. corporations are required to report foreign income and may be eligible for a foreign tax credit to avoid double taxation on that income. Failure to report foreign income or claiming incorrect foreign tax credits can result in penalties or additional tax liabilities.
How to Avoid This Error: Be sure to report all foreign income on Form 1120, including any income from subsidiaries, branches, or investments. Additionally, claim the foreign tax credit using IRS Form 1116 to avoid paying double tax on foreign-source income. Work with a tax advisor experienced in international tax law to ensure compliance with all reporting requirements.
