California Retirement Income Tax 2026: What Your IRA, RMD, and 401(k) Actually Cost
California taxes required minimum distributions, traditional IRA withdrawals, and 401(k) distributions at the full state income tax rate — with no retirement income exclusion of any kind. A retiree in Illinois taking $150,000 in annual RMDs owes Illinois $0. The same retiree in California owes up to $13,950 in state tax on those same distributions. Here's the exact calculation — and what you can do about it.
- IRA withdrawals and RMDs: Fully taxable at California ordinary income rates (up to 13.3%).1
- 401(k) and 403(b) distributions: Fully taxable. No employer-plan exemption.
- Pension income: Fully taxable (public or private). No pension exclusion for CA residents.
- Social Security: Fully exempt from California state tax (CA R&TC §17085).2 This is the only meaningful exemption CA offers retirees.
- Roth IRA distributions: Tax-free (qualified distributions), same as federal.
- Roth conversions: Taxable in the year of conversion at full CA rates — this is the strategy pivot point (see below).
2026 California income tax brackets — what retirees actually land in
California has nine progressive brackets plus a 1% Behavioral Health Services Tax (BHST) surtax on income over $1,000,000 (all filing statuses — the $1M threshold is NOT doubled for joint filers).1 The brackets are indexed annually to California CPI by the Franchise Tax Board.
| Rate | Single — 2026 taxable income | Married Filing Jointly — 2026 taxable income |
|---|---|---|
| 1% | $0 – $11,079 | $0 – $22,158 |
| 2% | $11,079 – $26,264 | $22,158 – $52,528 |
| 4% | $26,264 – $41,452 | $52,528 – $82,904 |
| 6% | $41,452 – $57,542 | $82,904 – $115,084 |
| 8% | $57,542 – $72,725 | $115,084 – $145,450 |
| 9.3% | $72,725 – $371,479 | $145,450 – $742,958 |
| 10.3% | $371,479 – $445,771 | $742,958 – $891,542 |
| 11.3% | $445,771 – $743,153 | $891,542 – $1,486,306 |
| 12.3% | $743,153 – $1,000,000 | $1,486,306+ |
| +1% BHST | Applies to all taxable income over $1,000,000 (all filing statuses — NOT doubled for MFJ) | |
| 13.3% effective | Over $1,000,000 | $1M+ income (BHST portion) |
Standard deduction: $5,706 (single) / $11,412 (MFJ). Brackets are approximate FTB-indexed 2026 values; see FTB.ca.gov for authoritative current-year rates.1
The key insight for most retirees: With California's modest standard deduction ($5,706 single), a retiree whose only non-SS income is a $100,000 RMD has $94,294 in CA taxable income — landing squarely in the 9.3% bracket. The 9.3% rate applies to roughly 90% of what most RMD-age Californians earn.
California retirement income tax calculator
Estimate your 2026 California state income tax on retirement income. Social Security is excluded (CA R&TC §17085 exempts it entirely).
What this means in dollars: four common scenarios
| Situation | CA taxable income | Est. CA state tax | Federal + CA combined rate |
|---|---|---|---|
| Single, $80K RMD, no other income | $74,294 | ~$3,350 | ~22% federal + 9.3% CA = ~31.3% marginal |
| MFJ, $120K RMD, $30K pension | $138,588 | ~$5,855 | ~22% federal + 8% CA = ~30% marginal |
| MFJ, $200K RMD, no other income | $188,588 | ~$10,416 | ~24% federal + 9.3% CA = ~33.3% marginal |
| Single, $400K RMD ($5M+ IRA), no other income | $394,294 | ~$33,336 | ~35% federal + 10.3% CA = ~45.3% marginal |
Federal brackets use 2026 rates per IRS Rev. Proc. 2025-32. California estimates use approximate 2026 FTB-indexed brackets.
Strategies for California residents with large RMDs
1. Qualified Charitable Distributions (QCDs) reduce CA income directly
A QCD from a traditional IRA to a qualifying charity is excluded from gross income at the federal level — and since California starts with federal adjusted gross income, the QCD exclusion flows through to your California return as well. The $111,000 annual QCD limit (2026) is excluded from your CA taxable income dollar-for-dollar.
At a 9.3% CA marginal rate, a $30,000 QCD saves $2,790 in California state tax in addition to the federal savings. For a charitably inclined retiree in California, the combined federal + state value of a QCD exceeds a standard charitable deduction by a significant margin — because the QCD reduces AGI (lowering IRMAA exposure and keeping Social Security provisional income down) rather than itemizing.

2. Time Roth conversions before vs. after leaving California
This is the highest-leverage planning move for California residents with large traditional IRAs who are considering relocating. Roth conversions are taxable in the year of conversion at full CA ordinary income rates — same as an RMD. If you convert $100,000 per year for 10 years while a California resident at the 9.3% rate, you owe approximately $93,000 in California state taxes on those conversions that you'd owe $0 on if you completed them after establishing residency in Florida, Texas, or Nevada.
The math becomes even more compelling for retirees with $2M–$5M in traditional IRAs. Completing $500,000 in Roth conversions after relocating avoids roughly $46,500 in California state taxes (at 9.3%) — and permanently reduces future RMDs from those converted balances.
If you're planning to leave California, convert AFTER you establish domicile in the new state. Converting before you move is an expensive mistake.

3. Manage the 9.3% bracket cliff
For a single California retiree, the jump from 8% to 9.3% happens at $72,725 in taxable income. For MFJ, it's $145,450. If your combined RMD and other income puts you right at the 9.3% threshold, partial Roth conversions in prior years or QCDs can hold income below the cliff and keep additional dollars taxed at 8% instead of 9.3%.
This bracket management also interacts with federal IRMAA thresholds (2026 Tier 1 begins at $106,000 single). A single California retiree with $100,000 in combined income is simultaneously in the federal 22% bracket, the CA 9.3% bracket, and at risk of crossing IRMAA Tier 1 — three simultaneous tax events from the same marginal dollar of income.

4. In-kind distributions from a taxable brokerage
This doesn't directly reduce CA taxes on RMDs, but it manages a closely related problem: California taxes capital gains as ordinary income (no preferential rate). If your taxable account holds appreciated securities, consider holding them rather than selling to fund living expenses — then use your RMD cash for spending. This keeps the taxable account's embedded gains deferred and steps up at death.
The relocation decision: what leaving California is worth
For retirees with $1M–$5M in traditional IRAs, the California income tax on RMDs represents a significant lifetime cost. A rough estimate for a MFJ couple:
| IRA balance at 73 | Annual RMD (ULT divisor 26.5) | Annual CA state tax on RMD | 20-year cumulative (static estimate) |
|---|---|---|---|
| $1,000,000 | ~$37,736 | ~$645 | ~$12,900 |
| $2,000,000 | ~$75,472 | ~$2,965 | ~$59,300 |
| $3,500,000 | ~$132,075 | ~$8,191 | ~$163,800 |
| $5,000,000 | ~$188,679 | ~$13,455 | ~$269,100 |
Single filer, RMD as sole income source (Social Security excluded per CA R&TC §17085). RMD divisor 26.5 per IRS Uniform Lifetime Table (T.D. 9930) at age 73. 20-year estimate is year-1 × 20 — actual CA taxes grow as divisors shrink and RMD amounts increase with age. For couples or those with pension/wage income, the incremental CA tax on RMDs depends on how brackets stack.
Federal law (4 U.S.C. §114) prohibits former California residents' retirement income from being taxed by California once they have genuinely changed domicile. Once you establish domicile in a no-income-tax state, all subsequent RMDs are free of California state tax — including distributions from accounts you funded entirely while living in California.
The FTB aggressively audits high-income individuals who claim to have changed domicile. Establishing non-California domicile requires genuinely moving (not a seasonal or temporary absence), severing the primary indicators of California ties, and maintaining documentation of the new state as your permanent home. California has 18 months to audit a domicile change after the reported move date.
California vs. other high-tax states: how it compares
| State | Retirement income exemption? | Top rate | Effective rate on $150K RMD (approx.) |

| California | None (SS exempt) | 13.3% | ~8–9% |
| Minnesota | None | 9.85% | ~7–8% |
| Oregon | None | 9.9% | ~7–8% |
| New York | $20K/person exclusion | 10.9% | ~5–7% |
| New Jersey | $75K/person if income <$150K | 10.75% | 0–6% |
| Florida / Texas / Nevada | No income tax | 0% | 0% |

- IRS Publication 590-B — Distributions from Individual Retirement Arrangements. Federal rules for IRA distributions; California conforms to federal AGI as the starting point for state taxable income, so distributions taxable at the federal level are also taxable in California.
- California Revenue and Taxation Code §17501. California's general conformity to federal gross income rules. Because QCDs are excluded from federal gross income (IRC §408(d)(8)), they are also excluded from California taxable income by conformity — unlike itemized deductions, which California treats separately.
- California FTB — Residency and Domicile. California taxes residents on worldwide income and has 18 months to audit a claimed domicile change. Relocating to a no-income-tax state eliminates California's right to tax subsequent RMDs under federal 4 U.S.C. §114.
