If you’re earning over $250,000 in California, you’re not just in a higher tax bracket—you’re in a completely different tax reality. The right high income tax strategy California business owners rely on involves more than basic deductions. It means entity layering, income deferral, and proactive compensation design to legally reduce tax exposure across both federal and state levels.
Once your income crosses the $250,000 mark, taxes in California become a different game. You’re no longer just looking for deductions—you need advanced strategies that protect income, reduce exposure, and optimize your structure without raising audit risk.
If you’re a business owner, consultant, or professional earning $250K+, the standard CPA approach won’t cut it. This guide outlines the advanced planning moves top earners use to keep more of what they make in 2025—especially in a high-tax state like California.
Quick Answer: Why High Earners in California Overpay
High-income earners pay more than necessary because they:
- Use basic tax prep instead of proactive planning
- Rely solely on deductions instead of restructuring income
- Miss out on legal strategies like entity layering, retirement stacking, and income shifting
- Let cash sit in the wrong places and get hit with unnecessary tax
At this income level, the strategies that matter most are about how your income flows—not just what you write off.
Common missed strategies:
- Splitting income between S Corp salary and distributions
- Using multiple entity types for service vs. investment income
- Hiring family members under favorable IRS rules
- Leveraging defined benefit or solo 401(k) contributions
- Reimbursing personal expenses through Accountable Plans
The Tax Reality of Earning Over $250K in California
Once your income exceeds $250K, the federal and state tax code treats you differently—especially in California.
Here’s what you’re dealing with:
- Federal marginal tax rate: 35–37%
- California income tax: 9.3% up to 12.3%
- Self-employment tax: 15.3% (if not structured correctly)
- Additional Medicare tax: 0.9% over $250K
- Net Investment Income Tax (NIIT): 3.8% on passive income
That means your effective tax rate could exceed 50% on certain income categories.
Why This Group Gets Hit Hard
Most high earners:
- Don’t track how much of their income is active vs. passive
- Don’t separate earned income from investment income strategically
- Have no written tax plan—just reactive filings each April
If you’re earning a high income without entity structure, retirement planning, or defined reimbursement rules, you’re likely losing $30K to $100K+ annually to preventable taxes.
The 5 Most Common Mistakes High Earners Make with Taxes
Earning a high income in California puts you on the radar of both the IRS and the FTB. But audits aren’t the only danger—many six-figure earners simply overpay because they aren’t using the right structure or strategies.
Here are the five biggest tax mistakes we see California business owners and professionals making once they cross the $250K mark.
1. No Entity Structure (or the Wrong One)
Many high earners still operate under their personal name or a single-member LLC taxed as a sole prop. That means:
- You’re paying self-employment tax on every dollar
- You can’t split income between salary and distributions
- You’re missing advanced deductions and fringe benefit strategies
What to do instead:
Use an S Corp or a layered structure (e.g., S Corp + management company + trust) to control how your income is taxed and unlock other strategies like retirement contributions, health reimbursements, and income splitting.
2. Not Paying Yourself a Reasonable Salary
If you’re already using an S Corp but not paying yourself a W-2 salary, you’re at risk of audit, penalties, and reclassification. On the other hand, if your salary is too high, you’re paying unnecessary payroll taxes.
Smart move:
Determine a “reasonable salary” based on your role and industry using tools like BLS.gov, and pay the remainder as distributions to reduce tax liability.
3. No Retirement Strategy Beyond an IRA
At your income level, a standard IRA does almost nothing.
What to do instead:
- Set up a Solo 401(k) or a Defined Benefit Plan
- Contribute both as employer and employee (up to $66,000+ in 2025 for Solo 401(k), or $100K+ for DB plans)
- Use these accounts to defer tax on income and build long-term wealth
A defined benefit plan can dramatically reduce your taxable income in high-earning years.
4. Missing Accountable Plan Reimbursements
If you’re paying personally for your cell phone, home office, internet, or other mixed-use expenses—you’re likely missing thousands in tax-free reimbursements.
High earners often forget these small adjustments because they’re focused on revenue, but with an Accountable Plan, these reimbursements:
- Are tax-free to you
- Are deductible to your business
- Require simple documentation, not complex filings
5. Relying on a Reactive CPA (Not a Strategist)
If your tax plan consists of “sending your numbers to the CPA in March,” you’re not tax planning—you’re tax reporting.
Most overpayments occur not because of what you did—but because of what you didn’t do on time:
- Entity election
- Salary adjustments
- 401(k) setup
- Real estate professional status validation
- Cost segregation timing
- Trust formation
Tax planning is proactive. If your CPA isn’t having quarterly strategy conversations, it’s likely costing you far more than you realize.
The more income you earn, the more scrutiny you attract—especially in California. A real high income tax strategy California firms implement includes audit-proofing deductions, running reasonable W-2 wages through payroll, and aligning your lifestyle with your reported income to avoid red flags.
Bottom line:
Making $250K+ should come with smarter systems, not higher penalties. Each of these mistakes is fixable—if you catch it in time.
High-Impact Tax Strategies for High Earners in 2025
If you’re earning $250K or more, the best tax savings won’t come from receipts or apps—they’ll come from strategy. This section breaks down the most effective tax moves available to high-income earners in California right now.
These are the same plays we use with real KDA clients to reduce their taxable income by tens (sometimes hundreds) of thousands per year—without raising audit risk.
1. Salary + Distribution Split via S Corp
This remains the most effective way to reduce self-employment tax. By structuring your business as an S Corporation, you can:
- Pay yourself a “reasonable salary” via W-2
- Take the remainder as owner distributions (not subject to SE tax)
- Save up to 15.3% on the distribution portion
Example: If you earn $300K and pay yourself a $120K salary, the remaining $180K avoids SE tax—resulting in a potential $27,540 savings.
2. Solo 401(k) + Defined Benefit Combo
For high earners, retirement accounts aren’t about deferral—they’re about control.
- A Solo 401(k) lets you contribute up to $66,000 in 2025
- A Defined Benefit Plan (DBP) can allow contributions of $100K–$250K+, depending on your age and income
Combined, these plans can reduce taxable income by over $300K annually—completely legal and fully audit-defensible.
3. Real Estate Professional Status + Cost Segregation
If you or your spouse can qualify as a Real Estate Professional under IRS rules, you can use cost segregation to:
- Accelerate depreciation
- Create passive losses
- Offset active income (including W-2 or S Corp income)
This strategy often unlocks six-figure deductions, especially when combined with short-term rentals and bonus depreciation timing.
4. Hiring Your Kids (Legally)
If you own an S Corp or LLC, you can put your children on payroll (age 7 and up is standard) and:
- Deduct their wages as a business expense
- Pay them up to $14,600/year tax-free (2025 standard deduction)
- Teach them real financial literacy and reinvest into Roth IRAs or custodial accounts
Make sure to document real duties and pay a market-based wage. We recommend using payroll software (like Gusto) and a written employment agreement.
5. Entity Layering with Trusts or Management Companies
Many high earners benefit from having multiple entities:
- An S Corp for main income
- A management LLC to shift income into a lower-bracket spouse or trust
- A revocable or irrevocable trust to control income streams and asset protection
While this is an advanced strategy, it’s essential for those approaching $500K+ in annual income or those building long-term assets (real estate, business equity, IP).
6. Augusta Rule + Accountable Plans
The Augusta Rule (Section 280A) allows your business to rent your personal residence for up to 14 days/year for business purposes, and:
- Deduct the rent expense from your S Corp
- Avoid reporting it as income on your personal return
Used properly with an Accountable Plan, this strategy can turn personal expenses (home office, internet, cell phone, etc.) into tax-free reimbursements.
Bottom line:
High earners don’t need more write-offs—they need better structure. These strategies work because they’re based on how you receive, classify, and direct income—not just what you spend.
KDA Case Study — How a Consultant Making $400K Saved $72,300 in Taxes Without Raising Red Flags

- Business: Executive coaching and strategy consulting
- Annual income: $402,000 (1099 income)
- Family: Married with two children
- Goals: Reduce tax liability, stay compliant, and begin building wealth outside of the business

Erik had built a successful solo consulting practice with high net margins—but his tax plan hadn’t evolved with his income.
- Still operating as a sole proprietor (no entity)
- Paid all income as self-employment, with no payroll structure
- No retirement accounts beyond a traditional IRA
- Paid for personal expenses like internet and home office out of pocket
- CPA was filing taxes, but never recommended planning ahead
Erik was paying over $140,000/year in combined federal, state, and self-employment taxes.

Here’s what KDA implemented over 90 days:
- Formed an S Corporation and filed Form 2553 for tax election
- Set a W-2 salary at $145,000, with the remaining income taken as distributions

- Created a Defined Benefit Plan to further defer taxable income
- Implemented an Accountable Plan to reimburse for:
- Home office use
- Internet and phone
- Monthly software subscriptions
- Home office use
- Used the Augusta Rule to rent Erik’s home for quarterly planning sessions
- Put both children (ages 10 and 12) on payroll to help with admin and media tasks
The Results
| Strategy | Tax Savings |
| S Corp structure (salary split) | $18,200 |
| Solo 401(k) contributions | $30,000 |
| Defined Benefit Plan | $17,000 |
| Accountable Plan reimbursements | $4,100 |
| Augusta Rule | $2,000 |
| Hiring children (income shifting) | $1,000+ |
| Total First-Year Tax Savings | $72,300 |
Erik also gained:
- A legal structure to scale his business
- Clean books and proper W-2 compliance
- Protection against audit risk with full documentation
- A strategy to reinvest tax savings into a Roth IRA and a new solo rental property
Erik’s feedback:
“I knew I was overpaying, but I didn’t realize how badly until I saw the savings laid out. KDA gave me a plan that actually matched the size of my business.”
