Instructions for Form 1120S 2011 Checklist
Purpose and Scope for Tax Year 2011
Form 1120-S for tax year 2011 serves as the annual income tax and information return for an S
corporation. The corporation uses the return to report income, deductions, credits, and distributions, and to provide shareholders with Schedule K-1 information for individual reporting.
The S election is made on Form 2553, and Form 1120-S applies for every year the election remains in effect.
The 2011 return follows rules specific to that tax year. It does not include stimulus reconciliation and does not apply later-law provisions enacted after 2011. The filing focuses on standard S corporation reporting, including nonseparately stated items and separately stated items that flow through to shareholders.
Core Concepts Applied Before Preparation
Schedule K is part of the Form 1120-S filing and summarizes items allocated to shareholders. A
Schedule K-1 is prepared for each shareholder and included as part of the assembled return in the instructed order. Schedule K and Schedule K-1 function as integral components of the return rather than optional or year-specific attachments.
Allocation rules also apply when ownership changes occur during the year. S corporation items generally follow a per-share, per-day allocation method. Year-end ownership percentages do not control allocations when shares transfer during 2011, and Schedule K-1 amounts must reflect ownership during the year.
Ten-Step Checklist for 1120S 2011
Step 1: Verify The S Corporation Election And Eligibility
Confirm that the S corporation election remained valid for tax year 2011 and that Form 2553 was filed timely with shareholder consent. Eligibility must be maintained throughout the year, and mid-year changes can affect compliance even if year-end conditions appear valid.
Confirmation should include that the corporation did not exceed 100 shareholders during the period the election was in effect. Verification should also include that the corporation maintained a single class of stock during 2011.
Step 2: Organize Identification And Filing Profile Information
Gather identifying and filing profile information so the return matches IRS records. Accurate setup information supports proper processing and reduces avoidable correspondence.
Corporate name, EIN, and business address should match IRS records. The principal business activity code and accounting method used for 2011 should be confirmed.
Step 3: Collect Shareholder Information With Year-Long Ownership
Considered
Assemble shareholder identifying information required for Schedule K-1 preparation and delivery. Ownership during the year must be tracked because allocations generally follow the per-share, per-day rule. Reliance on year-end ownership alone can misstate allocations when transfers occurred during 2011. Shareholder name, address, and Social Security number or EIN should be collected. Ownership changes during 2011 should be documented to support accurate allocation.
Step 4: Compile Income And Expense Records For The Full Year
Compile records supporting income and expense reporting for tax year 2011. Organized documentation supports accurate reporting on the main return and correct allocation on
Schedule K and Schedule K-1.
Gross receipts records and cost of goods sold support should be gathered when applicable.
Wage records, depreciation schedules, charitable contribution documentation, and other business expense records should be compiled.
Step 5: Build Schedule K Using Correct Item Categories
Prepare Schedule K using the required categories for nonseparately stated and separately stated items. Ordinary business income or loss is a nonseparately stated item and is not reported as a separately stated category. Separately stated items appear by category so shareholders can apply limitations and reporting rules correctly.
Ordinary business income or loss should be calculated for Schedule K reporting. Separately stated items such as net capital gains or losses, Section 1231 gains or losses, and tax-exempt interest income should be compiled when applicable.
Step 6: Complete Schedule K-1 For Each Shareholder
Prepare a Schedule K-1 for each shareholder to report that shareholder’s share of items reflected on Schedule K. Allocations should reflect ownership during the year, generally following the per-share, per-day rule when ownership changes occur.
Each Schedule K-1 should report the shareholder’s share of ordinary business income or loss and separately stated items. Required information items needed for AMT or other limitations should be included when applicable.
Step 7: Address Estimated Tax And Underpayment Rules When Applicable
Evaluate whether the corporation owes entity-level taxes that trigger estimated tax payment requirements. Estimated tax rules apply only to certain entity-level taxes and not to pass-through income itself.
Review should focus on built-in gains tax, excess net passive income tax, and investment credit recapture tax. Estimated tax payment requirements apply when the total of these taxes reaches
$500 or more.
Step 8: Assemble The Return Package In The Instructed Order
Assemble Form 1120-S with required schedules, forms, and statements in the order described in the instructions. Schedule K is included as part of the return and exceeds the due date included for each shareholder.
Schedule K and all Schedule K-1s should be included in the filing package. Supporting schedules and forms, such as depreciation or charitable contribution documentation, should be included when applicable.
Step 9: Sign The Return Using Authorized Signer Rules
Ensure the return is signed and dated by an authorized corporate officer. The signer must have authority under IRS rules, and fiduciaries sign when filing on behalf of the corporation in limited circumstances.
Authorized signers include corporate officers such as the president, vice president, treasurer, assistant treasurer, or chief accounting officer. When a paid preparer prepares the return, the
“Paid Preparer Use Only” section must be completed and signed.

- Tax relief options if you owe the IRS
Step 10: File By The Due Date Using Year-Specific Instructions
File the completed return by the 15th day of the third month after the end of the corporation’s tax year. A calendar-year 2011 S corporation return is due March 15, 2012. An automatic six-month extension is available by filing Form 7004 by the original due date.
The filing address should be selected using the “Where To File” table in the 2011 Instructions for
Form 1120-S. Filing addresses change over time, so year-specific instructions control for a 2011 paper filing.
Form-Specific Limitations And Eligibility Risks
A nonresident alien cannot be an S corporation shareholder, and loss of small business corporation status can terminate the S election. When a nonresident alien acquires stock, termination generally occurs when eligibility is lost, though relief may be available for inadvertent terminations when requirements are met.
Individual-level credits such as the Earned Income Credit are determined on the shareholder’s individual return and do not pass through from the S corporation on Schedule K-1. Schedule K-1 reports only the shareholder’s share of required S corporation income, deductions, credits, and information items.
Section Changes For 1120S 2011
Schedule K includes both nonseparately stated items and the corporation's stated items.
Ordinary business income or loss is reported as a nonseparately stated item and is not listed among separately stated categories. Separately stated items are reported by category so allocations remain accurate and shareholders can apply the appropriate reporting and limitation rules.
