IRS Form SS-8 Instructions
The difference between being an employee and being an independent contractor has never been more hazy than it is in today’s society. To help minimize the number of misclassified employees, the Internal Revenue Service created IRS Form SS-8, Determination of Worker Status for Purposes of Federal Employment Taxes and Income Tax Withholding.
In this tutorial, we’ll go over Form SS-8, including:
- Line by line detail on how to complete this form
- Reasons why a worker classification is important
- Frequently asked questions
Let’s start by walking through this form, step by step.
Table of contents
How do I complete IRS Form SS-8?
There are 5 parts to this five-page form:
- Part I: General Information
- Part II: Behavioral Control
- Part III: Financial Control
- Part IV: Relationship of the Worker and Firm
- Part V: For Service Providers or Salespersons
Before we get into Part I, let’s spend a little time at the top of Page 1.
Top of the form
There are three items at the top of the form that you should pay attention to:
- Information disclosure
- Things you should know
- Taxpayer information fields
Information disclosure
The disclosure section contains some important information for each of the involved parties. Primarily, any information that you provide to the IRS can be shared with the other party. So if you do not want to answer questions where you feel personal information will be shared with your employer, then do not complete IRS Form SS-8.
However, the IRS also states that this information can only be disclosed if it will assist with reaching a decision about the existence of an employee or independent contractor relationship with your company.

The IRS may need to gather information from both sides before issuing a determination letter about a worker’s status. For example, if a worker files Form SS-8, he or she should expect that any information will be disclosed to their employer.
The disclosure section even states, “If you do not want this information disclosed to other parties, do not file Form SS-8.”
Things you should know

Let’s go over some of the things that you should know, as pointed out on IRS Form SS-8.
- Complete IRS Form SS-8 in its entirety. If you do not give the Internal Revenue Service accurate and detailed information, you might not receive a favorable determination.
- Answer all questions clearly and concisely.
- Complete Part V unless you are:
- Providing a service directly to customers
- A salesperson
- Do not leave a question blank. You can enter ‘Unknown’ or ‘Not applicable’

- Include copies of the information returns for each year that you are contesting
- IRS Form W-2, Wage and Tax Statement

- IRS Form 1099-NEC, Nonemployee Compensation
At the top of the form, you’ll enter relevant information about the specific worker, as well as the company or firm employing the worker.
Taxpayer information
Most of the information fields are relatively straightforward. For example, you’ll want to include important information such as:
- Name of the worker and the firm
- Mailing address for both parties
- Email address, phone number, and fax number for both parties
- Firm’s employer identification number (EIN)
- Worker’s Social Security number (SSN)
Be sure to include as much contact information as possible, to ensure that the Internal Revenue Service has multiple ways to contact you for more information.
Also, if the worker is compensated by a third-party, enter the name, address, and employer identification number of the payer.

Frequently asked questions
Firms and workers file Form SS-8 with the IRS to request an IRS determination of the status of a worker for purposes of federal employment taxes and income tax withholding. Part of the determination includes identifying who should pay the employer’s share of FICA tax.
A company is responsible for withholding income taxes from an employee and for paying half of the overall FICA tax. An independent contractor is responsible for their own tax withholding and for paying self-employment taxes for Medicare and Social Security purposes.
