Beyond capital gains, the taxes that most shape a California retirement are property taxes under Proposition 13, income taxes on retirement account withdrawals, and Medicare premium adjustments, and each responds to planning you can start years ahead.
The Bottom Line
For California retirees, the tax picture beyond capital gains is dominated by: property taxes, where Proposition 13 limits the annual increase on an assessed base year value; regular income taxes on 401(k) and IRA withdrawals; and possible Medicare Part B/D premium surcharges tied to income. Nothing here is tax advice, and a licensed professional should confirm your situation.
The Taxes That Show Up in Retirement
1. Property taxes (Proposition 13)
- Property is taxed on an assessed value set near the purchase price, with annual increases capped by the voter-approved framework.
- A 55+ move means a new assessed value at the new home, unless a base-year value transfer like Proposition 19 applies.
- Reassessment timing is one of the biggest single tax decisions of a 55+ move.
2. Retirement account withdrawals
- Traditional 401(k)s, IRAs and pension income are generally taxable as ordinary income when withdrawn, at both federal and California rates.
- Roth accounts, funded with after-tax dollars, generally withdraw free of income tax.
- The order and amount you withdraw in a given year affects Medicare premium tiers.
3. Medicare premium adjustments
- Higher modified adjusted gross income can raise Medicare Part B and Part D premiums in a future year.
- RMD timing and Roth conversions interact with these tiers.
Why 55+ Buyers Should Plan Ahead
- A move changes your property tax baseline for the rest of ownership.
- Income timing (bonuses, conversions, RMDs, sale years) can cascade into premium tiers.
- California and federal rules are separate; confirm both.
