You must ensure that the information on Form W-2, Wage and Tax Statement, and Form W-3, Transmittal of Wage & Tax Statements, you issue to your employees contains correct retirement plan information because:
- employees need accurate information to determine the correct deductions and credits on their tax return, and
- IRS agents use the information from these forms to determine whether employers are complying with income and employment tax reporting requirements.
During Form 5500 examinations, IRS agents found employers using incorrect codes in Box 12 of Form W-2, for example:
- code D for 401(k) elective deferrals incorrectly included 403(b), 457, or non-qualified amounts.
- code E for 403(b) contributions but did not have a 403(b) plan.
- code H to incorrectly report health benefits; code H is for elective deferrals to a 501(c)(18)(D) tax-exempt organization plan. (In fact, a recent Employee Plan Compliance Unit project found that only 6 % of employers who used this code actually contributed to a 501(c)(18) plan.)
- code S for a SIMPLE 401(k); the correct code for a SIMPLE 401(k) is code D.

Form W-2, Box 13
The “Retirement plan” indicator in Box 13 shows whether an employee is an active participant in your company’s plan. If this box is checked, it lets the recipient know that depending on their filing status and modified adjusted gross income, they may not be entitled to a full deduction for their traditional IRA contributions. You should check the retirement plan box if an employee was an “active participant” for any part of the year in:
- a qualified pension, profit-sharing, or stock-bonus plan under Internal Revenue Code Section
401(a)(including a 401(k) plan).
- an annuity plan under IRC Section 403(a).
- an annuity contract or custodial account under IRC Section 403(b).
- a simplified employee pension (SEP) under IRC Section 408(k).
- a SIMPLE retirement account under IRC Section 408(p).
- a trust described in IRC Section 501(c)(18).
- a plan for federal, state, or local government employees or by an agency or instrumentality thereof (other than a 457(b) plan).
Generally, an employee is an active participant if covered by a:
- defined contribution plan (for example, a 401(k) plan) for any tax year and is credited with any contributions or forfeitures, or
- defined benefit plan for any tax year that the employee is eligible to participate.
Don’t check the retirement plan box if your company only has non-qualified or 457(b) plans.
Form W-3, Box b
Form W-3, Box b has checkboxes to specify the type of employer filing the form. You should check the appropriate box if you are a:
- non-governmental tax-exempt 501(c) organization;
- state or local government or instrumentality;
- state or local government or instrumentality and have received a determination letter from the IRS indicating that you are also a 501(c)(3) tax-exempt organization; or
- federal government entity or instrumentality.
Otherwise, you should check the “None apply” box. Only check one box.
