Roth Conversion in San Diego: the rules, the tax, and the next step
Roth Conversion here is a defense and military pensions problem shaped by a large military-and-defense retiree base whose federal pensions sit in the same tax year as IRA withdrawals, under California income tax — not a national brochure.
A Roth conversion is ordinary income this year — size it on purpose
You move pre-tax IRA or 401(k) money into a Roth and include the converted amount in ordinary income. The Roth then grows tax-free and has no lifetime RMDs. Partial conversions that stay inside a chosen federal bracket (plus the state layer, if any) usually beat converting the entire balance in one tax year.
Two rules surprise people: the 5-year clock on converted principal (a penalty risk before 59½) and IRMAA, which prices Medicare Parts B and D using MAGI from two years prior. Paying the tax from a non-IRA account is almost always cleaner than withholding from the conversion itself.
The local stack this page is actually about
Navy and Marine career pay, plus other defense pensions, already occupy ordinary-income space before anyone opens an IRA. Thrift Savings Plan withdrawals in the same year as a California-taxable conversion are the usual overshoot. FEHB-to-Medicare timing is a separate calendar from a conversion ladder; creditable employer coverage has to be documented before someone drops Part B. Biotech and hospital 403b plans add a second document in the same marriage. Payroll catch-up and a pension start date collide more often than a generic retire-at-65 article assumes. Checkable names on this page: Medi-Cal, CA LIC. 0F18934. For roth conversion, start from defense and military pensions and healthcare and biotech — a large military-and-defense retiree base whose federal pensions sit in the same tax year as IRA withdrawals, under California income tax — rather than a national template.
Industry mix and the planning load
Naval Base San Diego, Camp Pendleton careers, SPAWAR / NIWC civilian pay, and biotech campuses in La Jolla and Sorrento Valley set the mix. A twenty-year uniform retirement and a Scripps or Sharp hospital 403b are different documents. PCS orders move households more often than a civilian HR calendar. defense and military pensions and healthcare and biotech are the two pay-and-savings stacks we actually see. Population context: about 1.4 million residents (U.S. Census Bureau, ACS 2023 5-year estimates). The constraint we plan around is a large military-and-defense retiree base whose federal pensions sit in the same tax year as IRA withdrawals, under California income tax. Competition among advisors is high; that does not create a storefront and it does not change the statutes.
Conversion years stacked on defense and military pensions income
Deferred comp and 401(k) money from defense and military pensions make a single-year conversion easy to overshoot. A large military-and-defense retiree base whose federal pensions sit in the same tax year as IRA withdrawals, under California income tax California taxes ordinary income on a progressive scale that reaches 13.3% at the top (Franchise Tax Board, current personal income tax rates). IRMAA prices that spike two years later. Partial rungs beat “convert it all.” Advisor and product density is high, so the scarce thing is a written recommendation that survives a second set of eyes — not another seminar.
The gap year next to healthcare and biotech
Households leaving healthcare and biotech work before RMDs (age 73 for most under SECURE 2.0) have a cleaner ladder — unless a pension or Social Security already fills the bracket. Sequence conversions and withdrawals so the California + federal stack stays inside a planned bracket, and treat Medi-Cal eligibility as a multi-year project if nursing-home spend-down is on the table. Pay the tax from a non-IRA account.

How California changes the numbers
The planning math in California is usually federal plus state, not federal alone.
How a conversion is actually taxed
The converted dollars are added to the rest of that year’s taxable income.
The years the math is usually kind
The gap between retirement and RMDs (now starting at age 73 for most people under SECURE 2.
The all-at-once conversion
Converting $400,000 in one year to “be done” can push ordinary income through 32% or 35%, trigger IRMAA at the high brackets, and — in a state that taxes ordinary income — add a state bill on top.
Care, Medicaid, and the long stay
Long-term care in California is paid privately, through insurance, or through Medi-Cal after a person meets the program’s asset and income rules.
