Salary deferrals under a 401(k) plan are treated differently than other types of contributions for top heavy purposes. Deferrals made by key employees are considered employer contributions for purposes of determining the minimum top heavy contributions owed to non-key employees.
However, deferrals made by non-key employees do not count towards satisfaction of the required contribution. For example, if any key employee defers 3% or more of his compensation, the employer must make a 3% contribution for all eligible non-key employees.
Matching contributions in a 401(k) plan can be used towards satisfaction of the top heavy contribution. But such contributions may not cover the required minimum for those who deferred, and those who didn't defer would be entitled to a full top heavy contribution.
A safe harbor 401(k) plan is a plan that elects to eliminate the annual average deferral percentage (ADP) and average contribution percentage (ACP) nondiscrimination testing. It does so by providing either a 3% nonelective contribution for all eligible employees or matching contributions of at least 100% of the first 3% of compensation deferred, plus 50% of the next 2% of compensation deferred. An annual safe harbor notice must also be provided.
Safe harbor 401(k) plans are automatically deemed to be not top heavy if the only contributions to the plan are salary deferrals and either the 3% safe harbor nonelective contribution or the safe harbor match contribution. Additional match contributions can also be made as long as they meet the ACP safe harbor requirements.
Beginning in 2008, the same exemption applies to a Qualified Automatic Contribution Arrangement (QACA), which is a type of safe harbor 401(k) plan that utilizes an automatic enrollment feature.
The top heavy exemption provides an added incentive for some employers to elect safe harbor status.
Although a safe harbor 401(k) plan may be exempt from the top heavy rules, it can still be part of an aggregated top heavy group. In that case, employer contributions under the 401(k) plan can be used towards the contribution requirements of the top heavy group.
Safe harbor plans that provide additional contributions from those mentioned above (including forfeiture allocations) are not exempt from the top heavy rules. This can create some surprising results.
A plan that would be top heavy if not for the exemption would lose its exemption by making even a small profit sharing contribution. But this contribution, together with other employer contributions under the plan (such as the safe harbor match), may not be sufficient to meet the top heavy requirements. As a result, the employer might be obligated to contribute thousands of dollars more than it originally intended.
A similar situation can occur when forfeitures are allocated resulting in the elimination of the top heavy exemption. For this reason, it is wise to design a safe harbor 401(k) plan so that forfeitures are used to offset future contributions or pay administrative expenses.
Keep in mind that in a straight profit sharing plan without salary deferrals, the top heavy contribution requirement can be met simply by allocating the contributions and forfeitures proportionately by compensation. Then every participant would receive the same allocation rate as the key employees. The scenario changes in 401(k) plans due to the treatment of key employee deferrals.
The increased popularity of 401(k) plans has limited the number of retirement plans considered to be top heavy. When a plan is top heavy it must provide certain minimum benefits or contributions, and defined benefit plans must use one of the accelerated vesting schedules.
Some safe harbor plans are exempt from the top heavy requirements, but additional contributions or forfeiture allocations to those plans can eliminate the exemption and create further contribution obligations. Advanced planning can help prevent some unexpected consequences and keep plans in compliance with the top heavy rules.
