How to invest after maxing out a 401(k) as a physician

I have maxed out my 401(k), so the next account is obvious

The next account is not automatic. An HSA, backdoor Roth, 457(b), and taxable account solve different problems, so treating them as four interchangeable savings slots can leave a physician short of usable cash.

The first decision is reversibility. Money you might need before ordinary retirement age should not all sit where access depends on plan rules, tax rules, or employment status. A taxable account may be preferable when a practice decision, early retirement, or health change is plausible, even when another account offers stronger tax treatment.

Assante Wealth Management would first separate dollars for near-term access from dollars intended for retirement or heirs. Fewer accounts help only when each account has a job you can explain at home.

The HSA is always the best next dollar

An HSA is useful only when your health plan makes you eligible, the account's investment and reimbursement rules fit your situation, and you can handle near-term medical costs. Before contributing, verify eligibility, the plan's investment menu, reimbursement process, and whether you need the money soon. A family HSA limit of $8,750 for 2026 is meaningful, but an ineligible contribution can create tax work and penalties.

A Roth account cannot help a late saver

A backdoor Roth can still add tax-free retirement assets late in a career. Before the conversion, though, any pretax money in traditional, SEP, or SIMPLE IRAs has to be counted, because those balances can make part of the conversion taxable. Form 8606 has to be filed correctly. For a physician's spouse or other beneficiary, inherited Roth money usually carries a lighter income-tax burden than pretax money. Beneficiary and distribution rules still apply, and a Roth label does nothing to stop the investments from falling in value.

A 457(b) is just another 401(k)

Governmental and non-governmental 457(b) plans are not interchangeable. Access, creditor exposure, distribution provisions, and rollover choices can differ, so read the plan summary before treating a 457(b) as a cash reserve. A careful physician can place every extra dollar into restricted accounts, then need $30,000 for a part-time transition. With nothing accessible left, the choices are an early withdrawal with tax and possible penalty, a loan, or waiting on whatever the plan's distribution schedule allows.

Which account belongs next to my 401(k)?

After the 401(k) limit is filled, first set aside the dollars you may need before retirement in a taxable account, as Miriam does below. Next, fund an HSA only when you are eligible and it is useful. Then compare the backdoor Roth and the 457(b) by access and employer-plan risk. The order shifts when early retirement is near, taxable savings are already large, or a spouse or heir may depend on the account.

The table answers one practical question: what job should each account perform after the 401(k) is full? The access column matters as much as the tax column for a late-career physician.

Hypothetical: Miriam is 58, divorced, a radiologist and partner in a private group. She has $2.4 million, mostly in a 401(k) and cash balance plan, and $36,000 of new savings after filling her 401(k). She wants $12,000 accessible if part-time reads become necessary. She keeps $12,000 in a taxable account for that reserve.

She contributes $8,750 to an eligible family HSA, leaving $15,250. She uses $7,500 for a Roth IRA contribution through the backdoor process, leaving $7,750 for a 457(b), but only after reviewing its non-governmental plan terms. The arithmetic is $36,000 − $12,000 − $8,750 − $7,500 = $7,750.

That allocation leaves Miriam with a reserve if she shifts to part-time work, while limiting the amount exposed to employer-plan restrictions. If she retires at 60, the taxable reserve can help bridge the early years. If she works until 62, the same reserve remains available for a health change or practice decision. Her beneficiary forms still need review, because the account that is easiest for her to access may not be the account with the cleanest result for an heir.

Gather the latest account statements, the 401(k) summary plan description, health-plan eligibility details, IRA balances, beneficiary forms, and the retirement-income dates under consideration. A single physician nearing retirement may value access more than a married physician with ample taxable savings. A small balance may favor fewer accounts; a large balance makes tax location and heir consequences more material.

At home, start with the person affected by access and inheritance. Miriam and the person she expects to receive her assets should first agree on the dollar amount that stays reversible, then discuss account labels. That order keeps the conversation about the household's choices, not a contest between account types.

What would Assante Wealth Management look at first?

Assante Wealth Management would first place Miriam's 401(k), cash balance plan, any IRA, and accessible cash on one page beside the retirement-at-60, retirement-at-62, and part-time-read options. The review would identify which dollars can fund a bad year or health change, then show the cost and family effect of each next-account choice before any change is made.

The same process can support physician financial planning, student loan planning, cash balance plan decisions, practice transition planning, investment management for doctors, and tax planning for high earners when those topics affect the account order. Assante Wealth Management meets with clients remotely, on video calls or by phone. A physician outside Pennsylvania can go through the same review, and the result stays a short list of accounts.

Account eligibility and plan rules still need checking. The firm does not make a taxable account automatically superior; it gives that option more weight when restricted money would leave too little room for an early retirement, health change, or practice decision.
