For family-owned, service-based businesses in Los Angeles and Southern California, taxes aren’t just a seasonal burden they’re a strategic lever. The most successful business owners treat tax planning like a full-year discipline, not just a scramble come year end.

Here are seven tax moves that high-performing family business owners make before year-end to help preserve wealth, reduce surprises, and guard legacy. Use these as prompts to evaluate your plan, discuss with your advisor, and catch opportunities others miss.

1. Lock in Deductions (and Accelerate Expenses Wisely)

Many deductions must be booked by December 31 to count for the current year. High-performing owners review capital expenditures, bonus timing, equipment purchases, and maintenance work early enough to ensure they hit the books in time without jeopardizing cash flow.

Use model forecasts to see how much cushion you have before overextending to grab deductions.

2. Revisit Compensation & Max Out Retirement Contributions

Owners should review how salaries, bonuses and profit distributions are structured. Paying the right mix of W2 vs. pass-through income can optimize self-employment taxes and retirement plan contributions. Year-end is also the time to ensure reasonable compensation aligns with IRS standards – especially for S-Corp owners.

Employer and owner contributions to retirement plans (401(k), SEP IRA, Cash Balance Plans) are among the most tax-effective tools. But many business owners delay until close to year-end and risk underfunding. 

Monitor plan limits and funding deadlines well in advance. For family businesses, coordinating business financing with owner contributions can make a significant difference in taxable income.

3. Consider Roth Conversions During Lower-Income Years

When your business has a down year, your taxable income may drop enough to make Roth IRA/401(k) conversions appealing. You’ll pay tax now but potential future growth within the Roth becomes tax-free income. In a state like California, this move requires precise modeling, but done right, it can lock in long-term tax leverage and greater flexibility in retirement.

4. Review Entity Structure & Intercompany Allocation

Sometimes, shifting which entity bears what portion of income or expenses (e.g. between a service company and real estate entity) can optimize taxes. High-performing owners regularly revisit whether their current structure still fits, especially after acquisitions, new revenue streams, or changes in tax law.

5. Use Family-Directed Tax Strategies

Gifting among family members, income shifting, and intra-family loans have a place when used carefully. For example, gifting part of the business ownership to a child in a lower tax bracket may reduce the owner’s future tax burden. But you must be mindful of valuation discounts, gift tax limits, and IRS scrutiny.

6. Audit-Proof Financial Records

A clean set of books is your most powerful defense. Ensure your financials reconcile, personal and business accounts are separated, family transactions are documented, and everything aligns with tax filings. Doing this before December reduces risk and last-minute scrambles.

7. Plan for State & SALT Impacts

In high-tax states, state and local tax (SALT) caps and deductions matter more than elsewhere. Recent tax developments (e.g., changes to SALT deduction limits) may open up new opportunities or require adjustments. High-performing owners monitor state-level reforms and integrate them into their strategies before year-end.

How These Moves Fit Into Your Legacy Strategy

These tax moves aren’t isolated—they feed into bigger transitions: succession, business sale, gifting, and retirement. By layering them into your broader plan, you ensure each decision advances your business, supports your family, and protects the legacy you’re building.
