Pairing a Cash Balance plan with a 401(k)

Most Cash Balance plans for businesses with employees sit alongside a 401(k) profit sharing plan. Together they give owners the largest deduction for the least staff cost.

How the pieces stack up for an owner

Illustrative · owner age 55, pay $360,000, 2026 limits
401(k) salary deferral
$24,500
Catch-up deferral, age 50+
$8,000
Profit sharing contribution, 6% of pay
$21,600
Cash Balance pay credit
$275,000
Total for the owner
$329,100

The Cash Balance amount depends on age, pay, plan history, and staff. Owners age 60 to 63 can defer up to $11,250 in catch-up instead of $8,000.

What each plan does

Investment risk Each participant The employer
Flexibility Profit sharing is discretionary each year, with employee minimums needed to pass testing A required minimum every year

EXTREMELY IMPORTANT: The 6% deduction rule

When an employer sponsors both a defined benefit plan and a defined contribution plan, total deductions are subject to a combined limit. In practice, employer contributions to the 401(k) side are deductible up to 6% of eligible participants' pay without reducing the Cash Balance deduction. Salary deferrals don't count toward the 6%. Plans covered by the PBGC are exempt from the combined limit.

Safe harbor 401(k) plans

A safe harbor 401(k) avoids annual deferral testing and can satisfy the top-heavy minimum. Its contribution also counts toward the staff gateway, which often makes it a natural partner for a Cash Balance plan. Typically we recommend a 3% safe harbor to NHCEs only. This helps to satisfy testing while offering the most flexibility possible.
