Form 1120 Tax Year 2011: IRS-Accurate Filing Checklist
Year-Specific Context
For 2011, Form 1120 required entering merchant card and third-party payments as zero on line 1a, reflecting IRS reporting changes that year. The domestic production activities deduction remained available at a rate of nine percent of qualifying income. Schedule UTP (Uncertain Tax Position Statement) was newly required for corporations with assets of $100 million or more; corporations with assets between $10 million and $100 million faced a five-year phase-in beginning in 2010. The alternative minimum tax was applied to corporations in 2011; net operating loss rules permitted a two-year carryback.
Year-Specific Programs Applicable to 2011 Form 1120
No economic impact payment (stimulus) reconciliation, American Rescue Plan, or 2020 unemployment compensation exclusion applied to 2011. The domestic production activities deduction under IRC Section 199 remained in effect for 2011, allowing nine percent of qualified production activities income, subject to wage and taxable income limitations, to be available to qualifying corporations, including those engaged in manufacturing, construction, and agricultural production.
Ten-Step Filing Checklist for 2011 Form 1120
Step 1: Verify Entity Eligibility and Filing Requirement
Confirm that the entity is a domestic corporation required to file under IRC Section 11. Corporations generally must file whether or not they have taxable income unless exempt under Section 501. If a domestic entity elected to be taxed as a corporation using Form 8832, attach a copy of Form 8832 to this return.
Step 2: Determine Schedule M-3 Requirement
Check total assets reported on Schedule L at tax year-end. If total assets equal or exceed ten million dollars, complete and attach Schedule M-3 instead of Schedule M-1. Corporations with total assets of less than ten million may voluntarily file Schedule M-3.
Step 3: Determine Schedule UTP Filing Requirement
For 2010 tax returns filed in 2011, corporations with total assets of $100 million or more must file Schedule UTP, reporting uncertain tax positions. Corporations with total assets between $10 million and $100 million will be phased in beginning in 2010; consult the 2011 Schedule UTP instructions for your specific threshold.
Step 4: Line 1a—Merchant Card and Third-Party Payments
For tax year 2011, enter zero on line 1a regardless of actual merchant card receipts. Report other gross receipts on line 1b if applicable.
Step 5: Complete Income Lines 1–11; Assess Domestic Production Activities Deduction
Calculate total income (line 11) by summing gross profit, dividends, interest, rents, royalties, capital gains, and other income (lines 3–10) if the corporation qualifies for the domestic production activities deduction. Complete Form 8903 and enter the deduction on line 25. Qualifying activities include construction performed in the United States, electricity or potable water produced in the United States, films made at least fifty percent in the United States, architectural or engineering services for domestic construction, and tangible personal property created or developed in whole or in part in the United States.
Step 6: Complete Deductions Lines 12–26; Observe Charitable Contribution Limits
Enter officer compensation (line 12), salaries and wages (line 13), repairs and maintenance (line 14), bad debts (line 15), rents (line 16), taxes and licenses (line 17), interest (line 18), and charitable contributions (line 19). Charitable contributions to qualified organizations are limited to ten percent of taxable income computed without regard to net operating loss carrybacks. Depreciation from Form 4562 is entered on line 20. If applicable, attach Form 8903 for the domestic production activities deduction on line 25.
Step 7: Compute Taxable Income (Lines 28–30); Determine Net Operating Loss Treatment
Compute line 28 (taxable income before NOL and special deductions) by subtracting total deductions from total revenue. On Schedule K, line 11, determine whether the corporation is electing to forego the net operating loss carryback period. If not carried back, the corporation may bring forward a 2011 NOL to each of the two preceding tax years and carry forward any remaining loss indefinitely. Enter the NOL deduction on line 29a.
Step 8: Complete Schedule C for Dividends Received and Special Deductions
Suppose the corporation received dividends from domestic corporations, complete Schedule C, lines 1–20. Classify dividends as less-than-20%-owned domestic corporations (line 1; seventy percent special deduction), twenty-or-more-owned domestic corporations (line 2; eighty percent special deduction), or wholly owned subsidiaries (line 8; one hundred percent special deduction). Enter total dividends on line 19 and total special deductions on line 20; carry line 19 to page 1, line 4, and line 20 to page 1, line 29b.
Step 9: Complete Schedule J for Tax Computation and Payments
On Schedule J, Part I, report membership in a controlled group (line 1; attach Schedule O if yes), income tax (line 2), alternative minimum tax if applicable (lines 9a–9f), and total tax (line 11). The alternative minimum tax remains applicable to corporations in 2011; consult the 2011 Schedule J instructions for computation details. On Part II (lines 12–21), report estimated tax payments, prior year overpayment applied to estimated taxes, and refundable credits. Attach Form 2220 if an estimated tax penalty applies.
Step 10: Sign, Date, Assemble, and File with Required Schedules and Attachments
The return must be signed and dated by the president, vice president, treasurer, assistant treasurer, chief accounting officer, or other authorized corporate officer. Assemble schedules in the following order: Schedule N (if consolidated return), Schedule O (if controlled group), Form 4797 (capital gains/losses), Form 4562 (depreciation), Form 1125-A (cost of goods sold), and all other required forms and supporting statements.
Corporations filing a consolidated return must check Item A, box 1a, and attach Form 851, Affiliations Schedule. Corporations that are members of a controlled group must file Schedule O with the apportionment agreement. Verify that the corporation’s total assets are reported correctly on page 1, item D, and on Schedule L to confirm the Schedule M-3 versus Schedule M-1 requirement.
Significant Line and Schedule Changes for 2011 Form 1120
No major line redesigns were mandated for the 2011 Form 1120 compared to prior years. However, for 2011 reporting, the merchant card and third-party payment rule mandated entering zero on line 1a, thereby altering income reporting procedures from those of previous years.
Line 1a: Prior year instructions reported actual merchant card and third-party payment amounts. The 2011 instruction required entering zero for the 2011 tax year 2011 regardless of actual receipts. This section represents a clarified provision.
Line 25: The prior year's instructions stated that domestic production activities should be claimed if applicable. The 2011 instruction clarified that the domestic production activities deduction is available, limited to nine percent of qualified production activities income or taxable income, whichever is less, subject to the W-2 wage limitation. This section represents a clarified provision.
Form-Specific Limitations for 2011
Nonresident and Foreign Entity Restrictions: Form 1120 applies only to domestic corporations. Foreign corporations must file Form 1120-F. Foreign sales corporations file Form 1120-FSC, and real estate investment trusts file Form 1120-REIT. Life insurance companies file Form 1120-L.
Small Corporation Exception: Corporations with total receipts and total assets both less than two hundred fifty thousand dollars at year-end are not required to complete Schedules L (Balance Sheet), M-1 (Reconciliation of Income), and M-2 (Analysis of Retained Earnings); instead, they enter only total cash distributions and book value of property distributions.
Charitable Contribution Limitation: Charitable contributions deductible on line 19 are limited to ten percent of taxable income computed without regard to net operating loss carrybacks. Contributions exceeding this amount may not be deducted in the current year; consult Publication 526 for carryover rules.
