The portion of the premium paid by your employer.
Any premiums you paid through pre-tax deductions (e.g., through a cafeteria plan).

It is important to understand that this amount is not the same as your taxable income or the amount you paid in premiums. It is the total cost of the health insurance coverage, as determined by your employer and their insurance provider.

Difference Between Code DD and Other Box 12 Codes

Box 12 on your W-2 often includes other codes, each representing different types of compensation or benefits. Here’s how Code DD differs:

Code DD vs. Code W: Code W represents the total amount of money contributed to a health savings account (HSA). While both relate to health benefits, Code DD focuses on the cost of the health coverage itself, whereas Code W focuses on HSA contributions.
Code DD vs. Other Codes: Other codes in Box 12 can represent a wide range of benefits, such as dependent care benefits (Code C), non-taxable moving expense reimbursements (Code P), or adoption benefits (Code T). Each code has its specific meaning, and consulting the IRS instructions for Form W-2 can clarify each one.

Who Needs to Report Code DD?

Nearly all employers who provide health insurance coverage to their employees are required to report the cost of that coverage in Box 12, using Code DD. This requirement applies to both full-time and part-time employees. If you receive a W-2 form, it is highly likely that your employer will include Code DD if they offer health insurance.

How to Find and Understand Code DD on Your W-2

Locating and interpreting Code DD on your W-2 is straightforward.

Step-by-Step Guide to Locate Code DD

Find Box 12: Locate Box 12 on your W-2 form. It’s usually on the lower portion of the form. This box is labeled and contains multiple entries, each identified by a code letter (e.g., DD, W, C).
Identify Code DD: Look for the specific entry that includes the code "DD." Next to it, you'll see a dollar amount.
Understand the Amount: The dollar amount next to "DD" represents the total cost of your employer-sponsored health coverage.

Examples of Code DD in Action

Let's look at some scenarios to illustrate how Code DD might appear on your W-2:

Scenario 1: Employer pays the full premium: If your employer pays the entire premium for your health insurance, and you contribute nothing, Code DD will show the total amount the employer spent on your coverage.
Scenario 2: Employee and employer split the premium: If you and your employer split the cost, Code DD will still show the total cost, not just your portion. For example, if the total cost of your plan is $8,000 annually, Code DD would show $8,000, regardless of how much you and your employer each paid.
Scenario 3: High-deductible health plan (HDHP): Even if you have an HDHP with a health savings account (HSA), the value under Code DD will still represent the total cost of the health plan, not your HSA contributions.

Key Differences Between Code DD and Healthcare.gov

While Code DD provides details of your employer-sponsored health coverage, it’s distinct from the information presented on Healthcare.gov, the marketplace for purchasing individual health insurance. Here are some key differences:

Purpose: Code DD is informational and reported by employers to the IRS. Healthcare.gov is a marketplace where individuals can purchase health insurance plans and potentially receive subsidies.
Content: Code DD reports the cost of employer-sponsored coverage. Healthcare.gov provides details on available plans, including premiums, deductibles, and out-of-pocket maximums.
Who it applies to: Code DD applies to those with employer-sponsored health insurance. Healthcare.gov is primarily for individuals and families who do not have access to employer-sponsored coverage or who seek more affordable options.

Practical Implications and Actionable Steps

Understanding Code DD can empower you to make informed decisions about your health coverage and finances.

Making the Most of Code DD Information

Review Your W-2: Always carefully review your W-2 form, including Box 12, to ensure the information is accurate. If you notice any discrepancies, contact your employer's HR or payroll department.
Use it for Comparison: Use the amount reported in Code DD to compare the value of health insurance offered by different employers, if you are considering job changes.
No Tax Impact: Remember that the Code DD amount is not taxable. It is simply for informational purposes and does not affect your taxable income.
