KDA Case Study: How a Mission Viejo Family Saved $5K+
Meet the Johnsons, a Mission Viejo family with a W-2 tech employee dad earning $150,000, a 1099 freelance mom pulling $80,000 from graphic design, and two college-bound kids. Living near Lake Mission Viejo, they own a $1.2 million home and invest in a rental property in nearby Laguna Niguel. Last year, they came to KDA frustrated after overpaying $7,500 in taxes due to missed deductions and poor structuring—the dad couldn’t claim his home office despite remote work, and the mom’s LLC setup meant high self-employment taxes on her income.

First, we restructured the mom’s business to an S Corp, reducing her self-employment tax liability by $4,200 (from 15.3% on $80,000 to a reasonable salary setup—see IRS guidelines in Publication 15). Next, we optimized their home office deduction: The dad’s 250 sq ft space qualified under Pub 587, saving $1,250 at the simplified rate. We also bundled education expenses for the kids, claiming $2,500 per child in credits, and added $3,200 for solar panels installed on their roof, tying into California’s new brownfield incentives.
The total savings? $9,800 in the first year alone, against our $2,500 fee a 3.9x ROI. They paid via a one-time strategy session and quarterly check-ins.
