Schedule C Form 1040 (2011): Profit or Loss From Business
Schedule C reports net profit or loss from self-employment business activities for sole proprietors filing Form 1040. For the 2011 tax year, the Internal Revenue Service implemented new merchant card and third-party network transaction reporting requirements but deferred actual reporting. Taxpayers must enter zero on line 1a per explicit 2011 instruction changes reflecting this temporary reporting deferral, while reporting all gross receipts on line 1b, including any income reported on Form 1099-K.
This checklist provides comprehensive guidance for completing Schedule C for the 2011 tax year. The instructions reflect specific requirements and regulatory changes applicable to businesses operating during calendar year 2011.
Filing Steps
Step 1: Complete Header Information
Complete the header section with the proprietor's name, Social Security number, and business identification code from the 2011 Internal Revenue Service instructions. Verify the code matches the current Principal Business Activity list published by the Internal Revenue Service for the 2011 tax year. This code categorizes your business based on the type of product or service you offer.
Step 2: Material Participation Question
Answer question G regarding material participation in the 2011 operations accurately. If you answer 'no', consult the instructions for passive activity loss limitations, which apply only to non-participating owners. Material participation is determined by meeting at least one of seven tests outlined in the 2011 Schedule C instructions, including participation for more than 500 hours during the tax year or participation that constitutes substantially all participation in the activity.
Step 3: Report Income on Part I
Complete Part I income section following the specific 2011 requirements. On line 1a, enter zero as mandated for 2011 merchant card and third-party payments; do not enter actual card proceeds. The Internal Revenue Service deferred the requirement to report merchant card (credit and debit card) and third-party network payments for 2011, despite the establishment of a new reporting infrastructure.
Step 4: Gross Receipts and Other Income
Report gross receipts on line 1b from all sources other than those listed on lines 1a and 1c. Include any Form W-2 wages if the Statutory Employee box was checked on your 2011 W-2. Report all gross receipts on line 1b, including any income reported to you on Form 1099-K, Merchant Card and Third Party Network Payments, but exclude any W-2 income reportable on line 1c.
Step 5: Calculate Net Revenue
Calculate and enter total gross receipts on line 1d, then subtract returns, allowances, and adjustments on line 2 to derive net revenue on line 3. Since line 1a contains zero for 2011, line 1d will equal the amount from line 1b or line 1c. Ensure that all adjustments are adequately documented with supporting records.
Step 6: Cost of Goods Sold and Other Income
Obtain Cost of Goods Sold from Part III line 42 and subtract from net revenue. Enter the result on line 5, then add the other 2011 income on line 6, including federal and state gasoline or fuel tax credit or refund if applicable. Line 6 also includes amounts from finance reserve income, scrap sales, bad debts recovered, interest on notes and accounts receivable, and other miscellaneous business income.
Step 7: Business Expense Deductions
Complete Part II expense lines 8 through 27a using only ordinary and necessary business deductions allowed under the 2011 tax law. Ensure wages on line 26 exclude any employment tax credits paid in 2011. Deductions must be both ordinary (common and accepted in your trade or business) and necessary (helpful and appropriate for your trade or business) to qualify.
Step 8: Calculate Profit or Loss
Calculate tentative profit or loss on line 29. If claiming home office expenses, attach Form 8829 and enter the result on line 30, then compute final net profit or loss on line 31. The simplified home office deduction method was not available in 2011; therefore, all home office expense deductions require the attachment of Form 8829. This form calculates the allowable deduction based on the business percentage of your home.
Step 9: At-Risk Determination
For losses, determine the at-risk status and select either box 32a (all investments at risk) or box 32b (some investments not at risk). If box 32b applies, attach Form 6198 to the document at-risk limitation calculations. The at-risk rules limit the amount of loss you can deduct to the amount you have at risk in the activity.
Step 10: Inventory Documentation
If Part III applies to your business, document the inventory valuation method (cost, lower of cost or market, or other method) and report opening inventory, purchases, labor, materials, and closing inventory in accordance with the 2011 instructions. Businesses that produce, purchase, or sell merchandise must generally maintain inventory records and use the accrual method of accounting for purchases and sales.
Step 11: Vehicle Information
Complete Part IV vehicle information only if claiming car or truck expenses on line 9 and not required to file Form 4562. Provide the month, day, and year the vehicle was placed in service during 2011. You must provide information on the business use of your vehicle if you claim any car and truck expenses.
Step 12: Attach to Tax Return
Attach Schedule C to Form 1040 or Form 1040NR as applicable. Estates and trusts file Schedule C with Form 1041 instead of Form 1040. Ensure that all schedules and supporting documentation are assembled in the correct sequence, using Attachment Sequence Number 09 as indicated on the form.
Year-Specific Updates for 2011
Merchant Card Payment Reporting
The merchant card and third-party payment reporting structure changed for 2011. Line 1a requires entry of zero for the 2011 tax year only; this temporary deferral was specific to 2011 and does not apply to prior or subsequent years. Payment processors began issuing Form 1099-K for merchant card and third-party network transactions; however, taxpayers were not required to report these amounts separately on line 1a.
Material Participation Requirements
The 2011 instructions explicitly cross-reference passive activity loss rules for question G. If you answer no, you must consult detailed instructions regarding loss limitations applicable only to passive activities in 2011. Passive activity losses can generally only offset passive activity income, and special rules apply to rental real estate activities.
Fuel Tax Credit Reporting
The 2011 Schedule C instructions specify that certain federal and state gasoline or fuel tax credits or refunds must be included on line 6. Verify 2011 state-specific fuel tax credit eligibility based on your business operations and fuel usage. These credits apply to fuel used for specific business purposes, such as off-highway business use.
Form 8829 Requirement
The home office expense deduction in 2011 requires the attachment of Form 8829 for all taxpayers claiming this deduction. The simplified method option language does not appear in the 2011 Schedule C instructions because the Internal Revenue Service had not yet introduced this alternative calculation method at that time. The simplified method became available starting with tax year 2013 returns, which were filed in 2014.
Statutory Employee Treatment
Line 1c caution language in 2011 warns that income reported on Form W-2 with the "Statutory Employee" box checked requires careful review of the instructions before inclusion. This affects the computation of self-employment tax because statutory employees do not owe self-employment tax on these earnings. Social Security and Medicare taxes should have been withheld from statutory employee earnings by the employer.
Additional Considerations
The business standard mileage rate for 2011 increased to 51 cents per mile for miles driven before July 1, 2011, and 55.5 cents per mile for miles driven after June 30, 2011. Taxpayers using the standard mileage rate must multiply business miles by the appropriate rate and add parking fees and tolls.
Heavy highway vehicle use tax was extended through September 30, 2012, for the 2011 tax year. Businesses using particular highway trucks, truck-trailers, tractor-trailers, or buses in their trade or business may have to pay federal highway motor vehicle use tax and file Form 2290.
Information reporting requirements apply to businesses making certain payments during 2011. Taxpayers must file Form 1099-MISC for contract labor payments of $600 or more during the year, and various other payment types may require information returns.
