The case looks at a business owner who wants a larger retirement contribution and a better tax result without ignoring employee plan costs.

Dr. Abe Erskine

He wants to reduce taxes and catch up on retirement.

Like many business owners, Dr. Erskine invested in his family first and his business second. Near age 60, he realized his current savings pace might not support the retirement income he wanted.

GoalReduce taxes

$107,479 was his tax bill last year. He wanted help lowering it.

GoalRetirement savings

He was not sure he had enough saved for the retirement he wanted.

Practice facts

The numbers behind the case.

Dr. Erskine owns Vita-Ray Health, an LLC filing as an S corporation. The practice has five employees, $500,000 of income after business expenses, and a $107,479 tax bill from the prior year.

Business fair market value$1,500,000

Desired monthly retirement income at 67$20,000
Estimated monthly retirement income at 67$13,266.90
Estimated monthly shortfall$6,733.10
Goal: Reduce taxes

Start with the tax return.

The first goal is direct: reduce the tax burden. The source example shows before, after, and impact panels tied to Form 1040 lines, then explains that the larger tax savings came from the plan design behind the return.

Before

$470,000Form 1040 line 8b adjusted gross income
$0Form 1040 line 10 QBI deduction
$107,479Form 1040 line 16 total tax

After

$300,000Form 1040 line 8b adjusted gross income
$33,200Form 1040 line 10 QBI deduction
$46,851Form 1040 line 16 total tax

Impact

$53,140Taxes deferred
$7,488Taxes reduced
$60,628Total tax savings

The plan strategy in the example provides $60,628 in tax savings while raising Dr. Erskine's retirement contribution from $30,000 to $200,000.

How the plan works

The design pairs a 401(k) with a cash balance pension plan.

Before the review, Dr. Erskine used a SEP IRA. His team moved him to a retirement plan design that combines a cross-tested 401(k) plan with a cash balance pension plan.

Cross-tested 401(k) plan
Cash balance pension plan
"Combo" plan
The plan is useful only if the larger deductible contribution, employee costs, and administrative work all fit the business.
Plan costs

The owner contribution changed, and so did the cost.

The SEP IRA design allowed Dr. Erskine to contribute $30,000 for himself. The Combo Plan raised his modeled owner contribution to $200,000. It also raised the employee plan cost from $21,640 to $31,000.

Combo plan

The owner share explains why the design may be worth the extra work. Under the SEP IRA, 58% of each plan dollar went to Dr. Erskine. Under the Combo Plan, 89% did. Employees still received more dollars than before in the modeled plan.

Goal: Retirement savings

The bigger contribution closed the modeled income gap.

The tax result mattered, but retirement savings was the other goal. Dr. Erskine wanted $20,000 of monthly income at age 67. With the SEP IRA alone, the example shows a shortfall. With the Combo Plan, the modeled shortfall falls to $0.

Summary

Dr. Erskine had two goals.

He wanted to reduce taxes and increase retirement savings. The Combo Plan example addresses both: a larger owner contribution, more retirement dollars for employees, and a modeled retirement income result that meets his target.
