The determination can be complex and depends on the facts and circumstances of each case. The determination is based on whether the person for whom the services are performed has the right to control how the worker performs the services. It is not based merely on how the worker is paid, how often the worker is paid, or whether the work is part-time or full-time.
Three basic categories
There are three basic categories of factors that are relevant to determining a worker’s classification:
- Behavioral control (whether there is a right to direct or control how the worker does the work),
- Financial control (whether there is a right to direct or control the business part of the work), and
- Relationship of the parties (how the business and worker perceive the relationship).
For more information on employer-employee relationships, refer to Publication 15, (Circular E), Employer’s Tax Guide, and Publication 15-A, Employer’s Supplemental Tax Guide. Also, refer to Publication 1779, Independent Contractor or Employee.
If you would like the IRS to determine whether services are performed as an employee or independent contractor, you may submit Form SS-8, Determination of Worker Status for Purposes of Federal Employment Taxes and Income Tax Withholding.
Generally, if you are an independent contractor you are considered self-employed and should report your income (nonemployee compensation) on Schedule C (Form 1040), Profit or Loss From Business (Sole Proprietorship), or Schedule C-EZ (Form 1040), Net Profit From Business (Sole Proprietorship). Most self-employed individuals will need to pay self-employment tax (comprised of social security and Medicare taxes) if their income (net earnings from self-employment) is $400 or more. Use Schedule SE (Form 1040), Self-Employment Tax, to figure the tax due.
Generally, there is no tax withholding on income you receive as a self-employed individual as long as you provide your taxpayer identification number (TIN) to the payer. However, you may be subject to the requirement to make quarterly estimated tax payments. If you do not make timely estimated tax payments, the IRS may assess a penalty for an underpayment of estimated tax. For more information on estimated tax, refer to Publication 505, Tax Withholding and Estimated Tax. Unlike independent contractors, employees generally pay income tax and their share of social security and Medicare taxes through payroll deductions (withholding).
