Instructions for Form 1120S 2022 Checklist
Overview of Form 1120S for Tax Year 2022
Form 1120S for 2022 reports S corporation income, deductions, and credits that pass through to
shareholders using Schedule K and Schedule K-1. The return summarizes entity-level activity and separately stated items, while shareholders apply their limitations and calculations to their returns. Several TCJA-era rules remain relevant for 2022, including Section 199A reporting, depreciation rules, and shareholder-level limitations.
An S corporation prepares Schedule K to aggregate all reportable items before allocating them to shareholders through Schedule K-1. Shareholder reporting depends on ownership during the year, allocation rules, and the character of each item. The corporation’s responsibility centers on accurate reporting and timely furnishing of K-1s, not on calculating shareholder-level deductions or taxes.
Core Reporting Concepts for 2022
S corporations report ordinary business income or loss on Form 1120S and separately state items that require special treatment at the shareholder level. These items include capital gains and losses, charitable contributions, tax-exempt interest, Section 1231 gains, and Section 199A information. Shareholders use this information to complete their returns and apply applicable limitations.
Economic Impact Payments and Recovery Rebate Credits are individual matters and do not appear on Form 1120S or Schedule K-1. Similarly, unemployment compensation exclusions apply at the personal level and are not S corporation pass-through items. The corporation should avoid reporting individual-level credits or exclusions on Schedule K or Schedule K-1.
Ten-Step Checklist for Form 1120S 2022
Step 1: Verify Shareholder Information and Eligibility
Confirm the identity and eligibility of every shareholder who owned stock during any part of
2022. Eligible shareholders may include individuals, certain trusts, estates, and specific exempt organizations permitted under the rules. Nonresident aliens are not qualified shareholders, and their presence can result in the termination of S corporation status.
Step 2: Determine Ownership Periods and Allocation Method
Identify ownership changes during the year and determine allocations using the per-share, per-day rule, unless a valid election to close the books applies. Ownership timing affects each shareholder’s share of income, loss, and deductions. Accurate records support proper allocation on each Schedule K-1.
Step 3: Compile Income and Deduction Information
Gather records supporting gross receipts, cost of goods sold, operating expenses, and other deductions. Identify and categorize items that necessitate special reporting, such as capital transactions, charitable contributions, and tax-exempt income. Ordinary business income or loss is reported on Form 1120S and carried to Schedule K.
Step 4: Identify Separately Stated Items
Prepare a complete list of items that must be separately stated for shareholders. These items retain their character and affect shareholder-level calculations. Examples include capital gains and losses, Section 1231 gains, charitable contributions, and tax-exempt interest.
Step 5: Address Built-In Gains Tax When Applicable
Determine whether the corporation is subject to built-in gains tax due to conversion from C corporation status within the applicable recognition period. If appropriate, compute the net recognized built-in gain and apply the highest corporate tax rate under the rules. This tax is separate from ordinary business income.
Step 6: Prepare Schedule M-1 or Schedule M-3
Complete Schedule M-1 to reconcile book income to tax income unless Schedule M-3 applies.
Schedule M-1 focuses on the differences between accounting income and taxable income.
Distributions and accumulated adjustments are addressed on Schedule M-2, not within the M-1 reconciliation.
Step 7: Complete Schedule K
Summarize all income, deductions, credits, and other items on Schedule K. Include Section
199A-related information such as qualified business income items, allocable W-2 wages, and unadjusted basis of qualified property. Schedule K presents totals that must reconcile with the corporation’s reported activity.
Step 8: Prepare Schedule K-1 for Each Shareholder
Prepare a Schedule K-1 for each shareholder who owned stock during 2022. Report the shareholder’s pro rata share of Schedule K items based on ownership periods.
Schedule K-1 includes allocation percentages, the number of shares at the beginning and end of the year, and all required separately stated items.
Step 9: Attach Required Forms and Schedules
Attach forms required by the corporation’s activities, such as Schedule D for capital gains and losses or Form 4797 for sales of business property. Do not attach individual-level schedules unrelated to Form 1120S. Retain documentation supporting reported amounts and classifications.

Step 10: Sign, Assemble, and File the Return
An authorized officer must sign and date Form 1120S and include the title and identifying information. Assemble the return following the order specified in the 2022 instructions. Use the mailing address provided for 2022 filings when submitting a paper return.
Shareholder Loss and Basis Considerations
Loss limitations under Section 1366(d) apply at the shareholder level and depend on a stock and debt basis. The corporation does not calculate shareholder basis limitations on Schedule K.
Shareholders use information from Schedule K-1 and complete the required forms to determine allowable losses.
Charitable contributions and other deductions reduce shareholder basis rather than increase it.
Income items, including tax-exempt income, generally increase the basis. Accurate Schedule
K-1 reporting supports proper shareholder calculations.
Section 199A Information Reporting
The Section 199A deduction applies at the shareholder level, subject to statutory limitations and thresholds. For 2022, the S corporation provides shareholders with necessary information, including qualified business income items, allocable W-2 wages, and the unadjusted basis of qualified property. Shareholders compute the deduction and apply limitations on their returns.
The corporation does not compute the Section 199A deduction or apply wage or property limitations. Reporting focuses on providing complete and accurate information so shareholders can independently determine eligibility and amounts.
Form-Specific Limitations and Filing Notes
S corporations generally do not pay federal income tax, though limited entity-level tax obligations may apply under the Internal Revenue Code. The corporation cannot claim business deductions, credits, or exclusions for shareholders, and items are reported on each owner’s tax return based on individual circumstances, including self-employment tax treatment where applicable.
Under IRS guidelines issued by the Internal Revenue Service, some corporations may be exempt from filing Schedule L or Schedule M-1 if receipts and assets fall below set thresholds.
Schedule K-1 must still be provided to every shareholder by the required deadline, even if the return is inactive or an amended return is later filed.
Reporting Updates for 2022
The Section 199A report continues to emphasize clear disclosure of qualified business income information. The S corporation reports pro rata QBI items, allocable W-2 wages, and the unadjusted basis of qualified property so shareholders can compute the deduction. Limitations still apply to shareholders rather than to the company as a whole.
The 2022 reporting framework reinforces the distinction between entity-level reporting and shareholder-level tax computation. Accurate preparation of Schedule K and Schedule K-1 ensures compliance and supports shareholders in meeting their filing obligations.
