PROACTIVE TAX STRATEGY
How Can Salary Optimization Affect an Owner’s Tax Position?
A business owner with approximately $1 million in projected pass-through income needed a year-end tax strategy. We reviewed the owner’s compensation and overall tax position and identified an opportunity to increase W-2 compensation. We then modeled the strategy before implementation, including its effect on pass-through income, the QBI deduction, payroll taxes, PTE tax, and the owner’s federal and state tax position.
Owner W-2 compensation
$50,000
$300,000
K-1 income
$1,000,000
$725,000
QBI deduction
($55,000)
($145,000)
Taxable income
$995,000
$880,000
Federal income tax
$286,000
$248,000
Difference / Tax Reduction
–
$38,000
13.3%
LOWER PROJECTED
FEDERAL INCOME TAX
≈ $38,000 reduction
What the Analysis Showed
Increasing W-2 compensation increased the applicable wage limitation used in calculating the QBI deduction. The modeled strategy resulted in approximately $38,000 less federal income tax.
We also structured withholding through the owner’s compensation to cover the projected personal tax liability, eliminating the need for separate quarterly estimated tax payments and avoiding a projected balance due at filing.
When we later prepared the tax return, the actual results closely aligned with the projection.
BUSINESS ANALYSIS & PLANNING
Can the Business Support Another Employee and New Equipment?
An established healthcare business was considering hiring a $75,000 employee and investing in faster treatment equipment. The business had available appointment capacity, but the owner’s time and treatment duration limited how many patients could be served within existing working hours.
Using financial analysis and planning tools, we modeled how the additional payroll commitment and potential increase in patient capacity could affect operating performance. Using recent operating results as a baseline, the analysis modeled a gradual increase in patient volume as productivity improved with the additional employee and faster equipment.
How Could the Investment Affect Monthly Operating Profit?
Additional patient visits modeled: Sep +10 → Oct +25 → Nov +35 → Dec +40
Illustrative example based on a sanitized client scenario. Certain figures have been adjusted for presentation while preserving the underlying analytical assumptions.
What the Analysis Showed
The investment initially reduces operating profit as the business takes on the additional payroll cost. As patient volume increases under the modeled assumptions, operating profit returns to the recent baseline and moves above it by year-end—without requiring additional working hours from the owner.
The analysis gives the owner a financial framework for evaluating whether the expected increase in capacity justifies the additional commitment.
Planning assumptions: Recent operating performance was normalized to approximately $56,600 per month. The modeled scenario assumed the employee begins in August, new equipment is introduced in September, and additional patient visits gradually increase from 10 per month in September to 40 per month by December.
