What are W-3 Forms? FAQs and Helpful Tips

When it comes to payroll reporting in the United States, employers often find themselves juggling several important tax documents. Among them is the Form W-3, a companion document to the Form W-2. While most business owners and HR professionals are familiar with W-2s, fewer understand what W-3 forms are, who needs to file them, and how to complete them correctly. Filing errors can result in IRS penalties, so it’s essential to get this right.

In this article, we’ll break down everything you need to know about W-3 forms—from their purpose to filing deadlines, how to complete them, and even how technology can simplify the process.

1) What is a W-3 Form?

The Form W-3, officially known as the Transmittal of Wage and Tax Statements, is a summary form that accompanies Forms W-2 when they are sent to the Social Security Administration (SSA).

Think of it as a “cover sheet” for your W-2s. It consolidates all the information reported on the W-2s, such as total wages, tips, Social Security wages, Medicare wages, and federal income tax withheld.

In short, while W-2 forms provide details for individual employees, the W-3 summarizes those totals at the employer level.

2) What’s the Difference Between Form W-2 and Form W-3?

It’s easy to confuse the two since they are closely related, but they serve different purposes:

Form W-2: Reports an individual employee’s annual wages and taxes withheld. A copy is provided to both the employee and the SSA.
Form W-3: Summarizes all employee W-2s for the employer and is sent only to the SSA. Employees do not receive a W-3.

In other words, W-2s provide the details, and the W-3 provides the totals.

3) Who Must File Form W-3?

Every employer who issues Form W-2 to employees is generally required to also file a Form W-3 with the SSA. This includes:

Small businesses with just one employee
Large corporations with hundreds of employees
Nonprofit organizations
Government entities

However, there are a few exceptions. For example, if you file W-2s electronically through Business Services Online (BSO), the electronic filing system automatically generates the W-3 data, so you don’t need to submit a paper W-3.

4) When Do You Need to File W-3 and W-2 Forms?

The deadline to file W-3 and W-2 forms is January 31st of the year following the tax year being reported.

For example:

Wages paid in 2024 → W-2 and W-3 forms are due to the SSA by January 31, 2025.

Employers must also provide employees with their individual W-2s by this same deadline so employees can file their tax returns on time.

Late or incorrect filings may result in IRS penalties ranging from $60 to $310 per form, depending on how late the correction is made.

5) How to Complete Form W-3

Completing a W-3 form accurately is crucial to avoid delays and penalties. Here’s a breakdown of key sections you’ll encounter:

5.1) What is a W-3 Control Number?

The control number is an optional code assigned by employers to identify individual W-2 forms within their system. It helps with internal recordkeeping but is not required by the IRS or SSA.

5.2) Box b: Kind of Payer

Here, you’ll specify the type of employer you are. Options may include:

941: Most common employers (those filing Form 941 quarterly)
Military: For military employers
943: Agricultural employers
944: Small employers filing annually
945: For reporting federal income tax withheld on nonpayroll payments

5.3) Box b: Kind of Employer

This section identifies your business type, such as:

501(c)(nonprofit) organizations
State and local government employers
Federal government employers
Railroad employers

5.4) Boxes 1-18

These boxes summarize totals from all your employees’ W-2s, including:

Box 1: Wages, tips, and other compensation
Box 2: Federal income tax withheld
Box 3-6: Social Security and Medicare wages and taxes
Box 7-8: Tips and allocated tips
Box 10: Dependent care benefits
Box 12-14: Additional compensation items and codes
Box 16-18: State wages, income tax, and local wages

Each box must match the totals from your employees’ W-2s to the penny.

6) How to File a W-3

Employers have two main filing options:

Paper Filing
- Submit Copy A of all W-2s along with the W-3 form to the SSA.
- Must use official red-ink forms (no downloads or photocopies).
Electronic Filing (Preferred)
- Use the SSA’s Business Services Online (BSO).
- Electronic filing is faster, more accurate, and generates W-3 information automatically.
- Required for employers filing 250 or more W-2s.

7) Where Can You Get W-3 Forms?

You cannot simply print W-3 forms from the internet for official filing. The SSA requires scannable, red-ink forms. Employers can obtain them in several ways:

Order from the IRS via their online portal
Request by phone at 1-800-TAX-FORM (1-800-829-3676)
Tax software often generates W-2 and W-3 forms in the correct format
Payroll providers typically handle W-2 and W-3 filings on your behalf
