IRS Schedule C (Form 1040) (2015): Business Profit or Loss

What is IRS Schedule C (Form 1040) (2015) for

IRS Schedule C (Form 1040) (2015) is the schedule small business owners and sole proprietors use to report income and business expenses on a personal tax return for the tax year. It helps a sole proprietor calculate their net profit or loss by listing business income, allowable business expenses, and any necessary adjustments for tax purposes. It applies to individuals who operate a trade or business and are required to report income from self-employment or related activities on a federal tax form.

When You’d Use IRS Schedule C (Form 1040) (2015)

You would use this schedule when your business activity generates self-employment income that must be reported on your tax return.

• Operating a sole proprietorship: You would use this schedule when you run a sole proprietorship and must report income from ongoing business activity that is carried out for business purposes.
  
  
• Working as an independent contractor: You would use this schedule when performing services as an independent contractor and must report income earned outside of traditional employment.
  
  
• Receiving income as a statutory employee: You would use this schedule when you receive wages as a statutory employee that require separate reporting for tax purposes.
  
  
• Running a single-member LLC taxed as a sole proprietorship: You would use this schedule when your single-member LLC is treated as a legal business entity that files a C form 1040 instead of a partnership return.
  
  
• Filing late or amended personal returns: You would use this schedule when you need to file schedule information again because your original return requires corrections involving self-employment income.

If you need to file late or amended personal returns, submitting a complete Schedule C can help resolve an unfiled federal income tax return and ensure compliance with tax regulations.

Common Mistakes and How to Avoid Them

These errors appear frequently on IRS Schedule C (Form 1040) (2015) and should be avoided.

• Misclassifying workers as independent contractors: You can avoid this error by confirming whether workers fit the IRS's definition of employees or independent contractors, based on business entity and control factors.

What Happens After You File

Once you submit IRS Schedule C (Form 1040) (2015), the information is processed with your personal tax return so the IRS can verify profit or loss from your business activity. The amounts you report help determine self-employment taxes and may affect your total tax due for self-employment or any additional income you earn. The IRS may request clarification if the schedule shows unusual amounts or if filing schedule entries appear inconsistent with prior returns.
