Step-by-Step (High Level)

Step 1: Gather Financial and Tax Records

Collect the NAIC annual statement, prior year returns, and all supporting schedules, including premium income, dividends received deduction, and applicable bond credits. Having complete data ensures accurate tax computation.

Step 2: Complete the Form and Include All Schedules

Enter all amounts paid, gross receipts, and total tax due. Ensure the applicable box for calendar year or fiscal year filing is marked correctly before signing the corporation income tax return.

Step 3: Review Foreign Corporation and Controlled Group Details

If your company is a foreign corporation or part of a controlled group, disclose related entities, foreign country operations, and taxes paid under foreign tax credit rules. This ensures compliance with international reporting requirements.

Step 4: Submit and Pay Electronically

Use the e-file system to securely transmit the tax return for faster payment processing for federal income tax, estimated tax penalties, or amended returns.

Common Mistakes and How to Avoid Them

• Omitting the NAIC Annual Statement: Many insurance companies forget to include this attachment, which leads to rejected filings. Each filer should attach the annual statement to confirm premium and reserve calculations before submission.
  
  
• Incorrect EIN or Reporting Year: Some filers enter the wrong Employer Identification Number or tax year, which causes delays in processing. Each corporation should verify all identifying details before submitting the corporation's income tax return.
  
  
• Underpaying Estimated Taxes: Certain companies fail to make quarterly payments, which results in estimated tax penalties. Every filer must calculate expected tax liability accurately and pay on time to avoid penalties.
  
  
• Missing Schedule PH or Other Attachments: Some corporations exclude Schedule PH or Schedule D, which prevents complete reporting. Each company should attach all required schedules to support reporting taxable investment income and capital gains.
  
  
• Ignoring Penalty Notices: Many taxpayers overlook IRS penalty notices, which increases liabilities over time. Every filer should respond promptly to all notices or consult a tax professional for assistance.
  
  
• Incorrect Tax Computation: Some filers misstate book income or deductions, which alters the total tax due. Each company should review all tax computation steps under the Internal Revenue Code for accuracy before submission.
