Retirement Tax Strategy Overview
Retirement planning and tax planning are inseparable for California business owners and high-income individuals. California's 13.3% top income tax rate makes tax-deferred retirement savings particularly valuable — every dollar contributed to a retirement plan saves up to 50.3 cents in combined federal and California income tax. KDA integrates retirement planning into every client's annual tax strategy, ensuring retirement plan contributions are maximized and distributions are structured to minimize lifetime taxes.

Roth vs. Traditional: California Perspective
The Roth vs. traditional decision is more complex for California residents than for residents of other states. Traditional contributions reduce current income tax at up to 50.3% combined rate. Roth contributions are made with after-tax dollars but grow and are withdrawn tax-free. The key question: will your tax rate be higher now or in retirement? For most high-income California residents, the current tax rate is very high — making traditional (pre-tax) contributions more advantageous. However, if you plan to leave California before retirement, Roth conversions done while in California may be disadvantageous — you pay California tax now but avoid it in a no-income-tax state in retirement.
Roth Conversion Strategy
A Roth conversion moves funds from a traditional IRA to a Roth IRA, paying income tax now in exchange for tax-free growth and withdrawals in retirement. KDA's Roth conversion strategy: (1) Convert in years when your income is temporarily lower (sabbatical, business transition, early retirement before Social Security begins). (2) Convert up to the top of your current tax bracket — but not into the next bracket. (3) Consider the impact on Medicare premiums (IRMAA surcharges apply at higher income levels). (4) For California residents planning to leave California, consider whether to convert before or after the move. (5) Model the break-even point — how many years of tax-free growth are needed to recover the conversion tax cost.
Required Minimum Distributions
Required Minimum Distributions (RMDs) are mandatory annual withdrawals from traditional IRAs and qualified retirement plans beginning at age 73 (under SECURE Act 2.0). RMDs are taxable as ordinary income — at up to 37% federal and 13.3% California. KDA's RMD planning strategies: (1) Roth conversions before RMDs begin — reduce the traditional IRA balance before age 73 to minimize future RMDs. (2) Qualified Charitable Distributions (QCDs) — direct up to $108,000 per year from your IRA to charity; the QCD satisfies your RMD and is excluded from income. (3) Aggregate RMDs — if you have multiple IRAs, you can take the total RMD from any one or combination of IRAs. (4) Still-working exception — if you are still working at 73, you can delay RMDs from your current employer's 401(k).
California Retirement Tax Rules
California has several state-specific retirement tax rules: (1) California taxes all retirement income — unlike many states, California does not exempt Social Security, pension income, or IRA distributions from state income tax. (2) California does not conform to the Roth IRA income limits — California follows federal Roth IRA rules, including the income limits for direct contributions. (3) California does not tax Social Security — wait, actually California does not tax Social Security benefits (this is one exception). (4) California pension income — California government pensions are taxable to California residents; out-of-state pensions are taxable if the recipient is a California resident. KDA provides California-specific retirement tax planning as part of every retirement strategy engagement.
