Nonelective contribution
Short definition
A nonelective contribution is an employer contribution made to every eligible employee, whether or not the employee defers. A 3% nonelective contribution is one way to satisfy the 401(k) safe harbor.
What a nonelective contribution is
Unlike a match, a nonelective contribution does not depend on what the employee saves. It comes in three forms. A safe harbor nonelective contribution is at least 3% of pay and is fully vested at once. A profit sharing contribution is discretionary and can vest over time. A qualified nonelective contribution (QNEC) is made to correct a failed test or an operational error.
Why it matters to employers
A nonelective contribution has a predictable cost and reaches employees who do not save. The safe harbor version can also be adopted late: up to 30 days before the plan year ends at 3% of pay, or by the end of the following plan year at 4%. It satisfies the top-heavy minimum contribution as well.
Example with 2026 figures
A company with $1,000,000 of eligible payroll makes a 3% safe harbor nonelective contribution of $30,000. An employee earning $60,000 receives $1,800 even if she defers nothing. Only the first $360,000 of pay counts in 2026, so the most any one person can receive at 3% is $10,800.
Common mistakes
Leaving out employees who left during the year or worked under 1,000 hours. A safe harbor nonelective contribution cannot carry those conditions.
Using a narrower definition of pay than the safe harbor rules allow.
Describing it to employees as a match.
Basic Capital and this term
Basic Capital’s Safe Harbor 401(k) supports the basic match, an enhanced match or the 3% nonelective contribution.
