Roth Conversion Planning for Los Angeles County Pre-Retirees

What a conversion actually does

A traditional IRA or 401(k) holds money that has never been taxed. You took a deduction going in, the balance grew tax deferred, and the tax is owed when it comes out. A Roth account holds money that has already been taxed, and qualified withdrawals come out tax free, including the growth, provided the distribution meets the applicable IRS requirements.

A conversion moves a chosen amount from the first category to the second and settles the tax bill on that amount now, at this year's rates, rather than later at whatever rates apply then. It is not a way to avoid tax. It is a way to choose the year in which the tax is paid, which is a different and narrower proposition.

Two mechanical points shape everything that follows. The income limits that restrict direct Roth contributions do not apply to conversions, so the strategy remains available to households whose income rules out contributing. And since 2018 a conversion cannot be undone. There is no recharacterization, no second look in April. Whatever is converted stays converted, which is precisely why the modeling belongs before the transaction rather than after it.

The pre-RMD window

Most households pass through a stretch of comparatively low taxable income between the end of employment and the start of required minimum distributions. Wages have stopped, Social Security may not have been claimed yet, and the pre-tax balances are still growing untouched. Required minimum distributions currently begin at age 73 under present law, rising to 75 later in the next decade, so for many people that window runs several years.

The planning logic is straightforward. Income drawn deliberately during those lower-income years is taxed at the rates that apply then, and every dollar converted is a dollar that will not be forced out later as a required distribution taxed on top of Social Security and any other income. Left alone, a large pre-tax balance can produce distributions that land in a higher bracket than the household ever occupied while working.

What the window does not do is make conversion automatically correct. It makes it worth modeling. Whether a given household benefits depends on the balance, the expected future income, whether the tax can be paid from funds outside the account, and how long the converted money will sit before it is needed.

What a conversion touches

The reason conversion planning belongs in the same room as the rest of the retirement plan is that the added income does not stay in one place. It moves through several systems at once, each with its own thresholds and its own timing.

Thresholds and dollar amounts in each of these systems change and are indexed annually. Confirm current-year figures with your CPA rather than relying on any published table.

The Medicare row is the one households are most often surprised by, because the effect is delayed. Premium tiers are set from income reported two years earlier, so a conversion executed now can raise a premium bill that arrives well after the decision feels settled. That is not a reason to avoid converting. It is a reason to know the number before you act.

The 2025 federal tax act changed the backdrop by making the current individual rate structure permanent, which removed the scheduled sunset that had been driving a great deal of conversion urgency. It also added a temporary deduction for taxpayers age 65 and older that phases out as income rises. Because a conversion raises income, it can reduce or eliminate that deduction, so the deduction should not be read as shelter for conversion income. Both points are worth confirming against current law with your CPA, since tax legislation continues to move.

What California adds

California treats the converted amount as ordinary income and offers no preferential rate for it. State marginal rates run into the double digits at the top of the schedule, with an additional surcharge applying above a high income threshold, so for a Los Angeles County household the combined federal and state consequence of a large single-year conversion can be meaningfully different from the federal figure alone.

That arithmetic tends to push toward spreading conversions across several years rather than executing one large one, because filling the lower portion of a bracket in each of several years produces a different combined result from crossing into the top of the schedule once. Whether that holds for a given household is exactly what a projection is for.

Residency is the other California-specific variable. Households planning to relocate to a state with no income tax sometimes ask whether conversions should wait until after the move. The answer depends on the facts of the move, on when residency actually changes for tax purposes, and on the source rules that apply. It is a question for your CPA and, where the move is complex, your attorney. It should not be assumed either way.

Many households in the county hold large balances in employer plans from long careers in aerospace, entertainment, healthcare, and technology. Where those balances are still inside a workplace plan, the plan document itself governs what rollovers and in-plan conversions are permitted, and that constraint has to be read before a schedule is built rather than after.

When a conversion may not fit

Conversion planning gets discussed as though the answer is usually yes. It is not. Several circumstances argue against converting, or against converting now, and a firm that never raises them is not modeling carefully.

• The household is currently in a high bracket and expects a lower one later, which inverts the entire logic.
• There are no funds outside the retirement account to pay the tax, so the conversion would be partly consumed by its own tax bill.
• The converted money is likely to be needed soon, leaving little time for tax-free growth to matter.
• The household is close to a threshold where added income would trigger a disproportionate effect elsewhere, such as a Medicare tier or a phase-out.
• Charitable intent is significant, since pre-tax balances can be well suited to qualified charitable distributions or to a charitable beneficiary designation.
• Heirs are expected to be in lower brackets than the account owner, which changes the comparison.

How to evaluate an advisor

Verification first. Look the firm up by CRD number through the SEC adviser search or FINRA BrokerCheck, and read the Form ADV Part 2A brochure for services, compensation, and conflicts. Then ask the questions that reveal how the work is actually done.

• Which of your services carry a fiduciary duty and which do not? Ask for that in writing.
• Do you model conversions across multiple years, or evaluate a single year at a time?
• Which thresholds does your projection account for, and how do you handle the two-year Medicare lag?
• Do you model the California consequence alongside the federal one, or separately?
• How do you coordinate with my CPA, and at what point in the year does that conversation happen?
• How is the firm compensated, itemized by service line?
• What would make you recommend against converting?

That last question is often the most revealing. A conversion is a decision with real downside cases, and an advisor who can describe the circumstances under which they would advise against it is describing a process rather than a product.

How Avinci approaches it

Avinci Wealth Management is a Registered Investment Adviser registered in California, Arizona, Illinois, Texas, and Nevada, firm CRD #327780, with offices in Santa Clarita, Beverly Hills, and Woodland Hills. Insurance and annuity products are placed through our affiliate, Lucas Insurance Services, which earns commissions on the products it places, and that relationship is disclosed in our client agreements.

Conversion work here is modeling rather than execution of your tax filings. We build multi-year projections of income, bracket placement, and the thresholds listed above, using specialized income and tax modeling software including independent third-party platforms such as Income Lab, so a proposed schedule can be examined year by year before anything is converted. Those projections are then reviewed with your CPA, who prepares and signs the return.

Conversion timing is one input among several in The Retirement Blueprint, the documented four-step process that produces a single plan document covering investments, tax, income, insurance, and estate coordination. Because a conversion changes the tax character of assets that will eventually pass to heirs, it is examined alongside beneficiary designations rather than in isolation. Multi-year tax planning and withdrawal sequencing are handled by the same team that manages the portfolio.
