California Retirement Tax: Prop 19, Mello-Roos, Medi-Cal, and the 13.3% Trap

What California taxes, and what it doesn't

California's retirement tax treatment is more favorable than its overall reputation suggests, with several major exceptions.

California does NOT tax:

• Social Security benefits (federal taxation still applies)
• Railroad retirement benefits
• VA disability benefits
• Inheritances or estates (no state inheritance or estate tax)

California DOES tax (up to 13.3% top bracket):

• Traditional IRA and 401(k) withdrawals: fully taxed as ordinary income
• Pension income: fully taxed
• Annuity withdrawals: fully taxed
• Roth conversions: fully taxed in the year of conversion
• Capital gains: taxed as ordinary income (NO preferential rate, unlike federal)
• Qualified dividends: same as cap gains, no preferential rate
• Rental income

The headline rate for high-income CA retirees is 13.3% on income above $1.44M MFJ. The more practical number for most retirees is 9.3% (the bracket from $141K to $721K MFJ taxable income). California is one of only two states (with Hawaii) where state income tax hits double digits.

Prop 19, the inherited rental property bomb

Proposition 19 passed November 2020, effective February 16, 2021. It fundamentally changed parent-to-child property transfers at death.

Before Prop 19 (Prop 58 era)

Parents could transfer their primary residence to children with the property tax assessment fully preserved. Up to $1 million of any other California property (rentals, vacation homes) could also transfer with assessment preserved.

After Prop 19

• Primary residence: Children can still inherit the assessment IF they make it their primary residence within one year. There's a $1 million inflation-adjusted exclusion above the current assessed value.
• Rental property, vacation homes, commercial property: Full reassessment to current market value. The $1M exclusion is gone for these.

A rental purchased in 1990 for $300K, assessed at roughly $400K (Prop 13 inflation), now worth $1.5M, gets reassessed at $1.5M the moment it transfers to the kids. Annual property tax jumps from roughly $4,500 to approximately $15,500, a 3.4x increase.

What to do with appreciated CA rental property

Hold to death (still works for primary residence step-up)

The federal step-up basis at death still works: your heirs get a clean cost basis at fair market value. Combined with the primary-residence Prop 19 exception (if they'll live there), powerful. For non-primary residences, the property tax reassessment is the new cost.

Sell and use a structured installment sale

Instead of recognizing a $1.5M capital gain in one year (crossing into the 13.3% bracket, triggering IRMAA, plus federal 20% LTCG), spread recognition over 5-30 years via a structured installment sale (IRC Section 453). Each year stays in lower brackets. The buyer pays cash at closing; an assignment company pays you on a schedule.

1031 exchange into a Delaware statutory trust

Exchange the property into a Delaware statutory trust holding institutional commercial real estate. Defer all gain. Hold until death; heirs get step-up basis. No active management on your part.

This is a major part of my practice. For California sellers with $500K+ embedded gains, the structured installment sale or Delaware statutory trust options often save $300K-$600K vs lump-sum sale. Fill out the form below if you want a written analysis on your specific property.

Medi-Cal: what changed in 2024

Medi-Cal is California's Medicaid program. For seniors needing long-term care, Medi-Cal eligibility historically required either being below an asset limit (~$130K single, $195K couples) or doing Medicaid planning (gifting, irrevocable trusts) to qualify.

As of January 1, 2024, California eliminated the asset test for Medi-Cal. Only an income test remains.

Implications:

• Middle-class families with $400K+ assets can now qualify for Medi-Cal LTC if income stays under the threshold. California is now more generous than federal Medicaid.
• Estate recovery still applies after death, though enforcement varies.
• Income management is the new planning lever. Roth conversions, QCDs, MYGA timing all become more important than asset-shelter strategies.

For CA retirees worried about LTC catastrophic risk, this is potentially the most favorable Medicaid environment in the country. Hybrid LTC insurance and asset-based LTC products are still relevant if you want to preserve full asset flexibility. But "Medi-Cal as backstop" is now a much more viable plan than pre-2024.

The Roth conversion case for CA retirees

California taxes Roth conversions at the same ordinary income rates as IRA withdrawals, up to 13.3%. This makes the conversion math marginally less favorable than in no-state-tax states like Texas, Florida, or Nevada.

But the case is still strongly positive for most CA retirees:

• The state will tax the IRA eventually, either when you take RMDs or when you convert. The decision is when, not whether.
• Pre-conversion (in your 60s, before SS, before RMDs) often happens in lower CA brackets than post-RMD income would.
• If you plan to move out of California in retirement: convert in CA BEFORE the move. CA loses the right to tax future IRA withdrawals once you've changed domicile, but they retain the right to tax conversions that happen while you're a CA resident. So convert NOW (CA tax) → move → withdraw Roth tax-free anywhere = clean.
• The federal case is unchanged regardless of state. CA tax adds friction but rarely changes the directional conclusion.

For high-net-worth retirees planning to leave California, the pre-move conversion sequence is one of the cleanest tax plays available. Talk to a tax professional well before the move date.

Mello-Roos and the downsizing trap

California property tax is governed primarily by Prop 13 (1978), capping annual increases at 2% with reassessment at sale. One of the most favorable property tax environments for long-time owners.

The "Mello-Roos" wrinkle applies to certain newer developments (typically post-1982 statewide, post-1990s in many SoCal neighborhoods). Mello-Roos refers to Community Facilities Districts levying additional special taxes on top of the base 1% Prop 13 rate, often 0.5-2% additional, sometimes more.

For retirees considering downsizing within California:

• The new home will reassess at market value AND may carry Mello-Roos special tax.
• Your property tax bill can easily 5x even if you "downsize" by square footage.
• Prop 19 portability rules help in some cases (parent's assessment transferable to a smaller home of similar value, with conditions). Verify with your county.
• Selling appreciated CA real estate triggers CA capital gains tax (ordinary income rate, up to 13.3%) plus federal LTCG plus NIIT plus IRMAA. The total bite can easily reach 35-40% of the gain.

The structured installment sale conversation becomes urgent for anyone considering a large CA real-estate transaction.
