What Are Elective Deferral Plans?
Elective deferral plans are retirement arrangements that let employees choose to defer part of their compensation into a tax-favored plan. The deferred amount may be pre-tax, Roth, or both, depending on the plan type and plan document.
The term is a broad category rather than one specific plan. Common examples include 401(k) plans, 403(b) plans, SIMPLE IRA plans, and salary reduction simplified employee pension arrangements, or SARSEPs.
Key Takeaways
- Employees elect to defer pay instead of receiving it as current cash compensation.
- Deferrals may be pre-tax or designated Roth if the plan permits Roth contributions.
- Annual elective deferral limits apply across several plan types.
- Employer contributions are separate from employee elective deferrals.
Which Plans Use Elective Deferrals
Plan type | How elective deferrals show up |
|---|---|
401(k) | Employee salary deferrals to a workplace retirement plan. |
403(b) | Salary reduction contributions for eligible schools, nonprofits, and ministries. |
SIMPLE IRA | Employee salary reduction contributions with required employer contributions. |
SARSEP | Older SEP arrangement that permits salary reduction contributions. |
Tax Treatment and Limits
Pre-tax elective deferrals reduce current taxable wages for income tax purposes, while designated Roth deferrals are made with after-tax dollars. Both can grow inside the retirement plan, but withdrawals are taxed differently. Pre-tax withdrawals are generally taxable; qualified Roth distributions can be tax-free.
The elective deferral limit is separate from the total annual additions limit that also counts employer matching and nonelective contributions. Participants with more than one job or more than one plan need to monitor combined deferrals across plans.
How This Differs From Employer Contributions
An elective deferral is the employee’s choice to save part of pay. A matching contribution, profit-sharing contribution, or nonelective contribution is employer money. Both can appear in the same account, but the limits, tax reporting, and vesting treatment can differ.
Payroll and Tax Reporting
Elective deferrals usually happen through payroll. The employer withholds the elected amount and sends it to the plan or IRA arrangement under the applicable timing rules. The employee’s Form W-2 generally reflects whether the employee was covered by a retirement plan and may show coded deferral amounts.
Because the annual limit applies across multiple elective deferral arrangements, employees with two jobs or midyear job changes should track their own combined deferrals. One employer may not know what the employee deferred under another employer’s plan.
What Can Go Wrong
Common issues include excess deferrals, missed payroll elections, late deposits, incorrect Roth or pre-tax coding, and confusion between employee deferrals and employer match. These are operational details, but they affect taxes, contribution limits, and plan corrections.
The Bottom Line
Elective deferral plans are workplace retirement arrangements built around an employee’s choice to save wages in a tax-favored account. The key is understanding the plan type, deferral limit, tax treatment, and how employee money differs from employer contributions.
