The Ultimate Tax Play for California Business Owners
By default, the IRS taxes single-member LLCs and sole proprietorships aggressively. Every dollar of net profit you generate is subject to a 15.3% self-employment tax (FICA/Medicare) on top of your standard federal and California state income taxes. For consultants, trade contractors, and professional practices clearing over $80,000–$100,000 in net income, remaining a standard LLC is one of the most expensive mistakes you can make.
By electing to be taxed as an S-Corporation under Subchapter S of the Internal Revenue Code, you split your income into two distinct categories: a W-2 salary and an owner’s distribution. The owner’s distribution is completely exempt from the 15.3% self-employment tax.
At Moontree Tax, we handle the entire conversion lifecycle. From calculating an audit-proof Reasonable Compensation salary and filing IRS Form 2553 (including late-election relief), to activating the California AB 150 PTE tax election to bypass the federal $10,000 SALT cap. We integrate your new 1120-S corporate return perfectly with your High-Net-Worth Private Client Tax Advisory.
Strategic Warning: How S-Corps Affect Your Section 199A QBI Deduction
Converting to an S-Corp completely changes how the IRS calculates your 20% Section 199A QBI Deduction. W-2 wages paid to an S-Corp owner are *not* eligible for the 20% write-off. Before executing an S-Corp conversion, we run advanced tax modeling to ensure the FICA tax savings from the conversion actually outweigh any potential reduction in your federal QBI deduction, guaranteeing you the lowest possible net tax liability.
The Math: LLC vs. S-Corporation
- The Scenario: A California tech consultant or agency owner nets $200,000 in profit for the year.
- Standard LLC Result: The owner pays 15.3% self-employment tax on the entire $200,000. Total FICA Tax: ~$26,000.
- Moontree S-Corp Result: We restructure the entity and establish a defensible “Reasonable Compensation” W-2 salary of $90,000. The remaining $110,000 is taken as a tax-free distribution (exempt from FICA). New FICA Tax: ~$13,770.
- Net Impact: A direct, recurring cash savings of over $12,200 per year, simply by optimizing the tax classification of the exact same business income.

Frequently Asked Questions About S-Corp Conversions
Is it too late to elect S-Corp status for this tax year?
Not necessarily. The standard IRS deadline is March 15th for calendar-year businesses. However, under Revenue Procedure 2013-30, we can frequently secure late-election relief for clients, backdating the S-Corp status to January 1st of the current year provided you have “reasonable cause” for the delay.
What is the California 1.5% S-Corporation tax?
Unlike the federal government, California imposes a 1.5% state franchise tax on S-Corporation net net income, with a minimum payment of $800 per year. Even with this 1.5% tax, the savings from eliminating the 15.3% federal self-employment tax makes the S-Corp highly lucrative for businesses generating over $80,000 in net profit.
Do I need to run formal payroll if I am the only employee?
Yes. To remain compliant as an S-Corp, you must operate formal payroll to issue yourself a W-2 for your “Reasonable Compensation” before taking tax-free distributions. We help our clients set up streamlined payroll systems (like Gusto or ADP) to handle federal and state withholding automatically.
