Business owners can supercharge retirement savings with a cash balance plan before December 31.
In brief
Business owners can supercharge retirement savings with a cash balance plan before December 31. Profitable business owners can shelter up to $290,000 annually in pre-tax retirement contributions using a cash balance plan alongside their 401(k) before December 31. Originally reported by Kiplinger.

Layer No. 2: The cash balance plan most business owners have never modeled

A cash balance plan shelters up to $175,000 annually at age 50 and $290,000 at age 60 in pre-tax contributions.
The IRS lifetime funding cap under a defined-benefit structure
The IRS lifetime funding cap under a defined-benefit structure can reach approximately $3.7 million.
Why December 31 is not a suggestion
A cash balance plan cannot be established retroactively; contributions must begin before December 31 of the tax year.

A roofing contractor with over a decade of profitable business had never heard of a cash balance plan due to tax season timing.

The estate planning trap
Failing to coordinate retirement vehicles creates a tax time-bomb for heirs under the SECURE Act.
