What Is This Form
IRS Schedule C (Form 1040) is the Schedule C tax form that sole proprietors and self-employed individuals use to report business income and expenses for the tax year 2015. It calculates net profit or loss, which flows directly to your personal tax return and determines your self-employment tax obligation.
Late Filers
If you missed the original 2015 deadline, you can still file Schedule C to report self-employment income and reduce potential penalties for unfiled returns.
Multiple Income Sources
If you owned more than one business in 2015, you must file a separate Schedule C for each distinct business.
Itemizing Deductions
Ordinary and necessary business expenses reported on Schedule C reduce your net profit before you calculate adjusted gross income on your Form 1040.
Claiming 2015 Credits
Certain business-related credits available for tax year 2015 must be supported by a completed Schedule C showing net profit or loss from the eligible activity.
IRS Compliance
Accurate reporting of gross receipts, cost of goods sold, and business expenses on Schedule C is required for IRS compliance and supports your self-employment tax calculation.
Citizens Abroad / Military
U.S. citizens abroad and military members operating a sole proprietorship or receiving self-employment income must still file Schedule C as part of their federal return.
Eligibility
Use Schedule C to report sole-proprietor income or loss. For 2015, file if your net earnings from self-employment were at least $400 or if you otherwise met a filing requirement.
Late Filers
Individuals who did not file a 2015 return on time must still submit Schedule C for any unreported self-employment income.
Multiple Income Sources
If you owned more than one business in 2015, you must file a separate Schedule C for each distinct business.
Itemizing Deductions
Small business owners use Schedule C to deduct ordinary and necessary 2015 expenses from gross receipts before calculating adjusted gross income.
Claiming 2015 Credits
Taxpayers claiming business-related tax credits for 2015 must complete Schedule C to establish the underlying net profit or loss that makes those credits available.
IRS Compliance
For 2015, nonemployee compensation was reported on Form 1099-MISC, box 7; report sole proprietorship income on Schedule C if filing requirements apply.
Citizens Abroad / Military
U.S. citizens abroad and active-duty military with 2015 self-employment income or a sole proprietorship must still file Schedule C.
Step-by-Step
Complete the IRS Schedule C form by following each section in order — entering business information, income, expenses, and calculating net profit or loss before transferring the result to your 2015 Form 1040.
1. Gather Your Documents Before Starting
Before completing Schedule C, collect all records of gross receipts, 1099 forms, expense receipts, mileage logs, vehicle records, inventory records, and any prior-year Schedule C filings that reflect your 2015 business activity.
2. Choose the Correct Filing Status [2015 Only if applicable]
Your filing status on Form 1040 affects your standard deduction and tax brackets, but does not appear directly on Schedule C. For 2015, the five filing statuses are single, married filing jointly, married filing separately, head of household, and qualifying widow(er) with dependent child. Note that "Head of Household" requires meeting specific dependency and residency tests under 2015 IRS rules.
3. Report All Income on the Correct Lines [2015 Only if applicable]
On Schedule C, report all gross receipts and sales on line 1, returns and allowances on line 2, and other income, including federal and state fuel tax credits, on line 6. Your taxable business income is net profit after allowable deductions; self-employment tax generally applies if net earnings reach $400 or more.
4. Calculate Adjusted Gross Income (AGI)
For 2015, enter Schedule C net profit or allowable loss on Form 1040, line 12, and on Schedule SE, line 2, when applicable. Above-the-line adjustments include the deductible portion of self-employment tax, health insurance premiums, and SEP-IRA or SIMPLE plan contributions.
5. Choose Your Deductions and Apply Exemptions [2015 Only if applicable]
On Schedule C, deduct only ordinary and necessary business expenses. For Form 1040, choose the standard deduction or itemized deductions. Standard deduction amounts: single — $6,300; married filing jointly — $12,600; married filing separately — $6,300; head of household — $9,250; qualifying widow(er) — $12,600. Personal exemption is $4,000.
6. Claim the 2015-Specific Credit [2015 Only]
The EITC was available for 2015, with a maximum credit of $6,242 for three or more qualifying children. Attach Schedule EIC only when claiming the credit with a qualifying child.
Filing Deadline — April 18, 2016
The 2015 federal return deadline was April 18, 2016, due to Emancipation Day; Maine and Massachusetts filers had until April 19 due to Patriots' Day. Extensions ran to October 17, 2016. Interest and penalties have accrued since the original deadline.
Refund Deadline — Likely Expired
For most taxpayers, the 2015 refund deadline was April 18, 2019. Refund claims are generally allowed within three years of filing or two years of paying the tax, whichever is later, subject to statutory limits. Consult a tax professional regarding exceptions.
Processing Time — Allow Several Months
The IRS says an accurately completed past-due return takes approximately 6 weeks to process, though timing can vary. If you have a balance due, submit full payment with your return — the IRS applies interest from the original due date regardless of when you file.
E-Filing Restriction — Paper Mail Required [2015 Only]
IRS MeF generally accepts the current tax year and the two prior tax years. A 2015 individual return filed today must be paper-filed because 2015 is outside the years currently accepted for e-filing. More generally, the IRS instructs taxpayers to file past-due returns the same way and to the same location as an on-time return.
Missing W-2s or Tax Records for 2015?
If you are missing income records needed to complete your 2015 Schedule C or Form 1040, the IRS offers several official transcript options to help you reconstruct your income before filing.
IRS Wage & Income Transcript
An IRS wage & income transcript for 2015 shows all income reported to the IRS under your Social Security number, including 1099-MISC forms that reflect self-employment income used on Schedule C.
IRS Account Transcript
An IRS account transcript for 2015 shows payments made, penalties assessed, and prior filings — helping you confirm whether a return was submitted and what adjustments are needed.
Social Security Administration
The Social Security Administration maintains records of wages and self-employment income reported for 2015 and can provide earnings statements that may help reconstruct income amounts for Schedule C reporting.
Contact Prior Employers or Clients
If you worked as an independent contractor in 2015, contact former clients to request copies of any 1099 forms issued or confirmation of amounts paid.
Do not estimate income on Schedule C — use IRS transcripts and official records to ensure your figures match what the IRS received.
Missing W-2s or Tax Records?
You can still complete your return even without original records
If your 2015 Schedule C shows a net profit that results in unpaid self-employment or income tax, penalties, and interest have likely been building since April 2016. Filing now and understanding your options can significantly reduce what you ultimately owe.
Failure-to-File Penalty
(5% per month, up to 25%)
The failure-to-file penalty is generally 5% of unpaid tax per month, up to 25%. When both penalties apply in the same month, the failure-to-file penalty is reduced accordingly. A minimum penalty may apply after 60 days.
Failure-to-Pay Penalty
(0.5% per month + interest)
The failure-to-pay penalty is generally 0.5% of unpaid tax per month, up to 25%, plus interest. The rate may drop to 0.25% under an installment agreement or rise to 1% after a levy notice.
Penalty Abatement Options
(First-Time Abatement & Reasonable Cause)
First-time abate requires clean compliance for the prior three years. Reasonable cause may apply for illness or disasters — reliance on a tax professional generally does not qualify. Some requests can be made by phone or submitted with Form 843.
Filing now is always better than continued non-filing — when both penalties apply in the same month, failure-to-file is 4.5% versus 0.5% for failure-to-pay.

Avoiding these errors on your 2015 Schedule C reduces the risk of IRS rejection, processing delays, and missed credits.
- Using the wrong tax year form — Submitting a Schedule C from any year other than 2015 will result in rejection; always confirm the form revision date before filing.
- Missing Schedule EIC or 2015-specific credit attachments — Attach Schedule EIC when claiming EIC with a qualifying child; omitting it will delay processing of your return and refund.
- Wrong filing status label — Selecting an incorrect filing status on Form 1040 affects your standard deduction, tax bracket, and eligibility for credits tied to your 2015 Schedule C income.
- Applying Pease limitations incorrectly — The Pease limitation reduced itemized deductions for high-income 2015 filers; misapplying it leads to overclaimed deductions on returns with significant Schedule C income.
- Treating any self-employment income as tax-free — Schedule C net profit is included in your federal income-tax computation, but self-employment tax generally applies only if your net earnings from self-employment are $400 or more.
- Assuming a refund is still available — The window to claim a 2015 refund closed in April 2019; filing now eliminates penalties but will not produce a refund for most taxpayers.
- Missing or incorrect Social Security numbers — An incorrect SSN on Schedule C or Form 1040 will prevent the IRS from processing your return and may trigger identity-verification delays.
- Unsigned return — A paper-filed 2015 return without a valid signature — or both spouses' signatures on a joint return — is not considered filed and will be returned by the IRS.
- Missing required attachments — Attach Schedule SE when net self-employment earnings are $400 or more; attach Form 4562 only when claiming depreciation, amortization, or section 179 expense.
What is IRS Schedule C (Form 1040) (2015) used for?
IRS Schedule C (Form 1040) for tax year 2015 is used by sole proprietors, independent contractors, and self-employed individuals to report business income and deductible expenses. The resulting net profit or loss flows to Form 1040 and is used to calculate income tax and self-employment tax obligations for the year.
Can I still file a 2015 tax return?
Yes, you can still file a 2015 federal tax return, including Schedule C. The refund window closed in April 2019, so most taxpayers will not receive one. Filing stops the failure-to-file penalty, but failure-to-pay penalties and interest continue until the tax is paid.
Do sole proprietors always need to file Schedule C for 2015?
Use Schedule C to report sole-proprietor business income or loss. For 2015, file if net earnings from self-employment were at least $400 or if you otherwise met a filing requirement, including independent contractors and single-member LLC owners taxed as a sole proprietorship.
How does Schedule C net profit affect self-employment tax for 2015?
Schedule SE applies self-employment tax to 92.35% of net earnings. For 2015, the 12.4% Social Security portion applied up to $118,500, the 2.9% Medicare portion applied to all net earnings, and an additional 0.9% Medicare tax could apply above the threshold.
What business expenses are deductible on the 2015 Schedule C?
Deductible expenses must be ordinary and necessary to your trade or business. For 2015, allowable deductions include advertising, car and truck expenses, depreciation, insurance, legal and professional services, office expenses, rent, utilities, wages paid to employees, and the business-use portion of a home office if it meets IRS requirements.
Can I deduct vehicle expenses on my 2015 Schedule C?
For 2015, deduct vehicle expenses using either the standard mileage rate of 57.5 cents per mile or actual expenses such as fuel, insurance, and depreciation, subject to IRS rules. Maintain mileage logs documenting dates, destinations, and business purposes for all vehicle use claimed.
What happens if my 2015 Schedule C shows a net loss?
A net loss on your 2015 Schedule C generally reduces taxable income on Form 1040. A resulting net operating loss is carried back 2 years or forward up to 20 years under 2015 rules, unless you elected to waive the carryback. Passive activity rules may limit deductibility.
What should I do if I owe self-employment tax from my 2015 Schedule C and cannot pay in full?
If you owe self-employment tax and cannot pay in full, file your 2015 return as soon as possible to stop the failure-to-file penalty. Options include a payment plan via Form 9465, currently-not-collectible status, or an Offer in Compromise if your liability qualifies.
