W-9 vs. W-2: Understanding the Difference in Tax Forms

W-9 vs. W-2: Understanding the Difference in Tax Forms

Understanding different tax forms is essential for business owners to ensure smooth operations and avoid headaches come tax season. Two of the most commonly used forms that you will encounter are the W-2 and the W-9. While both are important for tax purposes, knowing when to use each one is key to keeping your business compliant with Internal Revenue Service (IRS) requirements.

This article will break down the key differences between the W-9 and W-2, clarifying who needs to file them, their respective implications for tax reporting, and how businesses classify their workforce. We will also briefly explore how Paystubsnow’s platform can streamline the process of generating and managing these essential financial documents.

Main Takeaways From This Article:

  • Form W-2 reports wages paid to employees, while Form W-9 gathers information from independent contractors.
  • Employers are responsible for withholding income tax, Social Security tax and Medicare tax from employee wages reported on Form W-2. Independent contractors reported on Form W-9 are generally responsible for making their own tax payments.
  • The level of control a business exerts over a worker’s activities is a key factor in determining whether they should be classified as an employee or an independent contractor.
  • Misclassifying workers can lead to hefty financial penalties and legal repercussions for businesses.

What Is a Form W-2?

The Wage and Tax Statement, officially known as Form W-2 , is a document that employers provide to each employee by January 31st of the following year. This form details the total wages paid to the employee during the calendar year and the amounts of taxes (both federal taxes and state income tax) withheld from their paychecks. The W-2 also includes information about any contributions to benefits such as retirement plans or health insurance.

What Is a Form W-9?

Form W-9 , or Request for Taxpayer Identification Number and Certification, is completed by independent contractors, freelancers, and other non-employee service providers to provide their Taxpayer Identification Number (TIN) to the hiring business. This TIN could be a Social Security number (SSN) for individuals or an Employer Identification Number (EIN) for businesses.

By submitting the W-9, contractors certify the accuracy of their TIN and confirm they are not subject to backup withholding due to previous underreporting of interest or dividends. The hiring business uses this information to report payments to the contractor on Form 1099-NEC or other relevant 1099 forms .

Key Differences of Form W-2 vs. W-9

Understanding the differences between Form W-2 and Form W-9 is essential for businesses to accurately classify their workforce and fulfill their tax obligations. Here are some critical distinctions:

Purpose of Each Form

Form W-2 reports wages paid to employees and the taxes withheld from those wages. It ensures that both the employee and the government have an accurate account of the employee’s earnings and tax liabilities for the year.

Form W-9, on the other hand, is primarily an information-gathering tool. It allows businesses to obtain the necessary information from independent contractors to accurately report the payments made to them to the IRS via Form 1099.

Who Completes the Form

Employers are responsible for completing Form W-2. They are required to fill out the form for each individual they have classified as an employee and paid wages to during the tax year.

Form W-9, on the other hand, is completed by independent contractors or freelance service providers and submitted to the business that is paying them. Once the W-9s are filled out and submitted, the businesses then securely store the forms in their databases.

Income Tax Withholding Requirements

For employees reported on Form W-2, employers are required to withhold federal income tax, as well as Social Security and Medicare taxes, from each paycheck. The amount withheld is based on the employee’s W-4 form, which they complete upon hiring.

Independent contractors reported on Form W-9 are not subject to income tax withholding by the paying entity. Instead, they are responsible for estimating their tax liability and making quarterly estimated tax payments directly to the IRS.

Year-End Reporting Forms Generated

Employees must reference their W-2s when filing their federal and state tax returns. Since these forms include critical information, guaranteeing their accuracy is essential to avoid complications with the IRS.

At year-end, if contractors earn $600 or more from a single client, the client is required to report those earnings on a 1099-NEC form using the information provided on the W-9.

IRS Filing and Tax Documentation

Employers are responsible for filing Form W-2 with the Social Security Administration (SSA), which then forwards the income tax information to the IRS. Employees use the information on their W-2 to file their individual income tax returns (Form 1040).

Businesses that receive Form W-9 from independent contractors use the information to prepare and file Form 1099-NEC with the IRS. The contractors use the information on the 1099-NEC to report their self-employment income on their tax returns.

Employee vs. Independent Contractor

A business owner has a conversation with an employee on a job site The IRS has specific criteria to help businesses classify their workers as employees or independent contractors:

Employment Status and Work Control

An employee works under a contract of employment that allows the employer to dictate when, where, and how the work is performed, for which the employer typically provides tools, equipment, and training.

An independent contractor, however, works on a project basis without ongoing commitments and has more control over how and when they perform their services. They often use their own tools and equipment and may work for multiple clients.

Tax Payments and Withholdings

As mentioned earlier, employers withhold taxes from employee wages, while independent contractors are responsible for their own estimated tax payments, which cover income tax and self-employment tax ( Social Security and Medicare taxes ).

Employee Benefits

Employees are often eligible for benefits like healthcare, retirement plans, and sick leave, while independent contractors do not receive any such benefits and are responsible for their own health insurance and retirement savings.

How to Classify Workers Properly

A group of employees stand together for a team briefing given by their boss Businesses need to follow some important steps when classifying workers to ensure compliance with legal and tax regulations. The steps are as follows:

1. Apply IRS Regulations to Worker Classification

The IRS uses a common-law test to determine worker status. This test generally considers three specific aspects:

  • Behavioral Control: This refers to the degree of control over how workers complete their tasks. Employees generally have more defined roles and responsibilities dictated by their employer.
  • Financial Control: This pertains to how a worker is compensated and whether they have the potential for profit or loss. Employees usually receive a steady paycheck, while independent contractors often invoice for services rendered.
  • Type of Relationship: This examines the nature of the relationship the worker and business share. For instance, if a worker is expected to perform work on an indefinite basis, they might be classified as an employee.

2. Review the Contract and Daily Work Relationship

While a written contract can specify the worker’s status, the IRS will look beyond the contract to the actual working relationship.

  • Red Flags That Suggest Employee Status:
  1. The worker is required to work specific hours or days and must perform the work on the employer’s premises.

  2. The worker is subject to close supervision and detailed instructions.

  3. The worker is paid a regular wage or salary.

  4. The employer provides most of the tools and materials.

  5. The worker is entitled to employee benefits.

  6. The relationship is ongoing rather than project-based.

  7. Indicators of Contractor Status:

  8. The worker has significant control over how and when the work is performed.

  9. The worker can work for multiple clients.

  10. The worker uses their own tools and equipment.

  11. The worker is paid a flat fee for a specific project.

  12. The worker is responsible for their own expenses.

  13. The worker operates under a written contract that clearly defines the project and deliverables.

3. Avoid Common Classification Mistakes

Worker classification mistakes can be costly. Using IRS guidelines, correctly distinguish between employees and contractors to avoid penalties. Verify details like control level and relationship nature and regularly update classifications to ensure compliance and reduce financial repercussions.

Risks of Misclassification

An independent contractor reviews payment vouchers from their client Misclassifying employees as independent contractors carries substantial risks, especially for small businesses with limited resources. These can take the form of:

IRS Penalties for Tax Compliance Failures

The IRS can impose hefty penalties for failing to withhold and pay employment taxes and for failing to file accurate information returns (like Form W-2). These penalties can include fines and interest on the underpaid taxes.

Misclassified workers may have grounds to hold the company liable for a large sum of money because they were denied employee benefits. The company might be required to pay back wages and overtime pay and provide all those benefits that it had previously withheld.

State-Level Consequences

Many states have their own laws regarding worker classification, unemployment insurance, and workers' compensation. Misclassifying employees can lead to a number of complications, including liability for failure to comply with local labor laws and hefty state-level penalties. So, if you are a business owner, misclassifying your workers is generally not worth the risk.

Increased Audit Risk

Businesses with a high number of independent contractors relative to employees may be at a higher risk of an IRS audit focused on worker classification. This imbalance raises questions about worker classification, increasing the likelihood of costly penalties.

Loss of Trust and Reputation

Being found to have misclassified workers can damage a company’s reputation among employees, contractors, and the public. A damaged reputation can lead to difficulties in recruitment and retention, ultimately affecting the company's performance and ability to maintain relationships in the industry.
