Form 1120 for Tax Year 2022: IRS-Accurate Checklist
Year-Specific Uniqueness
Form 1120 for 2022 reflects post-CARES Act tax policy. Domestic C corporations filing for calendar year 2022 may claim retroactive credits for qualified sick and family leave wages paid during 2022 for leave taken from March 31, 2020, to October 1, 2021. No corporate alternative minimum tax (CAMT) applies to 2022 itself; CAMT begins for tax years starting after December 31, 2022.
Year-Specific Programs Applying to Form 1120, Tax Year 2022
Employers that paid qualified sick and family leave wages in 2022 for qualifying leave periods between March 31, 2020, and October 1, 2021, may claim a credit; no double tax benefit is allowed, and amounts claimed are reportable as income on Line 10. Form 1120-W has been discontinued; use Form 2220 if the underpayment penalty applies. The minimum penalty for failure to file a return more than 60 days late has increased; the actual threshold is stated in separate Form 2220 instructions.
Ten-Step Filing Checklist for Form 1120, Tax Year 2022
Step 1: Verify Entity and Year Identification
Confirm the corporation is domestic (U.S. incorporated). Enter the name, Employer Identification Number (EIN), and date incorporated on Form 1120, Page 1, Items B and C. Confirm tax year: calendar year 2022 or fiscal year beginning in 2022. Page 1, Item E: Check “Initial return,” “Final return,” “Name change,” or “Address change” if applicable.
Step 2: Gather and Calculate Income (Lines 1a–11)
Collect gross receipts or sales documentation (Line 1a). Deduct returns and allowances (Line 1b). Compute gross profit (Line 1c minus Line 2, cost of goods sold). Attach Form 1125-A if the corporation claims a COGS deduction. Gather documentation for dividends (Line 4), interest (Line 5), rents (Line 6), and royalties (Line 7). If capital gains apply, complete Schedule D (Form 1120) and attach. Determine other income (Line 10) and attach a statement if necessary. Sum Lines 3–10 for Line 11, Total Income.
Step 3: Attach Schedule C and Calculate Special Deductions
Complete Schedule C (Dividends, Inclusions, and Special Deductions) if the corporation received dividends or controlled foreign corporation inclusions. Report dividends by type (less-than-20%-owned domestic, 20%-or-more-owned domestic, foreign corporations, IC-DISC, other). Calculate the special deductions column © as (a) × (b) for each line. Enter Schedule C, line 24 total on Form 1120, Page 1, Line 29b.
Step 4: Calculate and Report All Deductions (Lines 12–29)
Line 12: Compensation of officers (attach Form 1125-E if total receipts are $500,000 or more). Lines 13–24: Itemize salaries, repairs, bad debts, rents, taxes, interest, charitable contributions, depreciation (Form 4562), depletion, advertising, pension plans, and employee benefits. Line 26: Other deductions with attached statements. Line 27: Sum Lines 12–26. Line 28: Taxable income before NOL and special deductions (Line 11 minus Line 27). Line 29a: Net operating loss deduction (only if the corporation has prior-year NOL carryover; see Schedule K, Question 11). Line 29c: Add Lines 29a and 29b. Line 30: Taxable income (Line 28 minus Line 29c).
Step 5: File Schedule UTP if Required
If the corporation has assets that equal or exceed $10 million at the end of the tax year, and if either the corporation or a related party issued audited financial statements for all or part of 2022, then Schedule UTP must be filed. The corporation has tax positions for which unrecognized tax benefits are recorded; complete and attach Schedule UTP (Form 1120). Report uncertain tax positions taken on the 2022 return or prior returns if an unrecognized tax benefit exists.
Step 6: Complete Schedule J (Tax Computation and Payment)
Part I: Check if the corporation is a member of a controlled group (attach Schedule O if yes). Line 1: Compute income tax using the applicable corporate tax rate. Lines 2–10: Calculate alternative minimum tax (only if applicable; CAMT does not apply to 2022). Line 11: Total tax. Part II (if applicable): Quarterly estimated tax reconciliation using Form 2220 if required. Part III: Enter refunds from prior year (Line 13), 2022 estimated tax payments (Line 14), overpayment application (Line 15), withholding (Lines 18–20). Line 23: Total payments and credits. Return to Page 1, Line 31 and Line 33.
Step 7: Complete Schedule K (Other Information)
Line 1: Enter accounting method (cash, accrual, or other). Line 2a–2c: Business activity code and principal business activity description. Questions 3–11: Answer Yes/No regarding ownership, investments, and NOL elections. Question 13: If total receipts and assets are both less than $250,000, the corporation may omit Schedules L, M-1, and M-2; otherwise, complete them. Question 14: If applicable, file Schedule UTP. Question 25: If certifying as a Qualified Opportunity Fund, attach Form 8996.
Step 8: Complete Schedule L (Balance Sheets) if Required
If Schedule K, Question 13, indicates assets or receipts exceed the $250,000 threshold, complete Schedule L, showing beginning and end-of-year totals for cash, receivables, inventories, investments, fixed assets, liabilities, and equity. Do not use the accrual method entirely for cash-method corporations; show book values.
Step 9: Complete Schedule M-1 or M-3 (Income Reconciliation) if Required
If the corporation's total assets on Schedule L equal or exceed $10 million at the end of the tax year, file Schedule M-3 (Form 1120) instead of Schedule M-1. If below $10 million, complete Schedule M-1 reconciling book income to taxable income. List adjustments for depreciation, charitable contributions, travel/entertainment, tax-exempt interest, and other permanent differences.
Step 10: Sign, Date, and Assemble for Paper Filing
Form 1120 signature area: A Corporate officer (president, vice president, treasurer, chief accounting officer, or other officer) must sign and date. If a paid preparer signs, they must include their Preparer Tax Identification Number (PTIN) and firm information.
Assemble attachments in order: Schedule N (if applicable), Schedules A–M in alphabetical order, Forms in numerical order (Form 851, Form 1125-A, Form 1125-E, Form 2220, Form 3115, Form 3468, Form 4562, Form 4797, Form 8824, Form 8949, Form 8996, Schedule D, Schedule G, Schedule J, Schedule K, Schedule L, Schedule M-1 or M-3, Schedule O, Schedule PH, Schedule UTP), then supporting statements.
See the IRS "Where to File" page for the 2022 Form 1120 mailing address, based on the corporation's state of incorporation. File by April 17, 2023 (calendar year 2022); use Form 7004 to request a six-month extension to October 17, 2023.
Form-Specific Limitations
Domestic Corporations Only
Only domestic U.S. corporations file Form 1120. Foreign corporations file Form 1120-F. Disregarded entities (single-member LLCs) that do not elect corporate taxation file under the owner’s return (Form 1040, Form 1065). S corporations file Form 1120-S; partnerships file Form 1065.
Net Operating Loss Carryback Restriction
A corporation electing to forego the carryback period (Schedule K, Question 11) must make the election by checking the box; no carryback to prior years is allowed if this box is checked. Only applies to future years. For NOLs arising in 2022, the corporation can carry back the losses only to the extent permitted under current law, which is limited to the lesser of the prior-year tax or the current-year tax after refiguring installments.
Form Changes, Additions, and Redesigns for 2022
Schedule K-2 and K-3 Reporting
Prior instruction (2021): Schedules K-2 and K-3 (Form 1065, Form 1120-S) were subject to transition relief and not uniformly required for domestic pass-through entities with no foreign activity.
Current instruction (2022): Final instructions were issued on December 20, 2022, and a domestic filing exception applies if the corporation meets three specific conditions: (1) no direct foreign partners/shareholders, (2) no foreign activity and no foreign taxes paid or accrued, and (3) no Schedule K-3 requests by one month before filing.
Change type: Clarified with expanded domestic filing exception.
Estimated Tax Penalty (Form 2220)
Prior instruction (2021): Form 1120-W provided estimated tax calculations.
Current instruction (2022): Form 1120-W is now historical; Form 2220 is used if an underpayment penalty applies. Corporations must file Form 2220 if a penalty is owed, even if the penalty amount is less than $500.
Change type: Redesigned (form replacement).
Key Compliance Notes
Corporations must maintain complete documentation supporting all income, deductions, and credits claimed on the 2022 return. For corporations claiming retroactive credits for qualified sick and family leave wages, proper substantiation of qualifying leave periods and wage amounts is essential. The transition from Form 1120-W to Form 2220 for estimated tax calculations requires careful attention to underpayment penalty calculations, particularly for corporations with fluctuating income throughout the year. Filing requirements for Schedule UTP apply to large corporations with uncertain tax positions, which require detailed disclosure of tax positions for which unrecognized tax benefits exist in their audited financial statements. Corporations should carefully review the Schedule K-2 and K-3 requirements, as the domestic filing exception provides relief for corporations with no foreign activity or foreign partners. All required schedules must be attached in the specified order to ensure proper IRS processing and avoid processing delays or correspondence requests.
