In 2026, smart California tax planning will help you pay less in taxes so that you can save more of your income and accumulate wealth despite increased expenses and regulations. This blog guides you on some of the top tax planning strategies for high-income earners in California in the year 2026.
Maximize Retirement Contributions
Retirement accounts protect taxable income now, which is not taxed until it is withdrawn. The high earners in the state of California are the main beneficiaries of filling them to the brim.
401(k) and 403(b): Make contributions of up to 23500 in 2026 (31000 in 2026 with 50+) and employer matching. The Roth options allow qualified withdrawals to be tax-exempt in the future.
SEP-IRA or Solo 401(k): Unemployed professionals can contribute their tax savings up to 69,000, which is best for consultants.
Deferred Comp Plans: Corporate plans or the ones of the public sector delay taxes on large bonuses.
Carry forward old accounts so that they can be used to avoid mandated distributions. This reduces future taxable earnings by a great margin.
Leverage Charitable Giving
Contribute appreciated stock or assets and avoid the capital gains taxes and deductions. The power of bunching donations in California is due to the federal conformity of California. It is one of the best tax reduction strategies.
- Write-offs immediately to Donor-Advised Funds (DAFs), and grant later.
- The IRA Qualified Charitable Distributions (QCDs) save taxable income for those who are 701/2 and above.
- Contribute to state deductions up to 50 percent of AGI by supporting local causes such as the Silicon Valley Community Foundation.
Stricter limits are likely to be in place in 2026, and so it is better to plan gifts before the end of the year.

- Defer gains from sales; 10% basis step-up after 5 years, full exclusion after 10.
- New investment targets start-ups and real estate.
- Watch federal changes, but the state still follows broadly.

- Qualified Business Income (QBI) Deduction: Pass-through income of up to 20 percent, which is phased out after $383,900 single, /767,800 married.
- Home office, mileage, and equipment deductions if compliant.
