For doctors, Roth vs traditional 401(k) decisions become clearer when Assante Wealth Management compares today’s tax savings with several later-life tax outcomes.
The usual assumption is that a doctor should always choose pre-tax contributions; the better answer depends on the tax rate attached to each dollar now and later.
You trade a tax reduction today for a possible tax-free source later. Late savers often underrate the risk of having only taxable retirement income when health, work, or tax law changes.
Assante Wealth Management wrote this page for physicians and dentists who earn well, still carry student loans, and may have a practice or partnership in the picture. We aim for a one-page plan you can explain at home. Where it fits, that means a smaller set of accounts and only a handful of funds.
A Roth choice is not a permanent bet on tax rates
Roth versus traditional comes down to two rates: the one on the contribution today and the one on the income you draw later. The account label settles nothing by itself. Assante Wealth Management treats the choice as risk control for a late saver. Keeping a Roth source and a pre-tax source gives you two ways to draw income if tax law or your retirement date moves.
A pre-tax contribution can lower taxable income today. A Roth contribution gives up that current reduction for qualified distributions that generally aren't included in federal taxable income. Neither account protects you from market risk. Your balance can fall, and you could end up with less than you put in.
The shortcut is practical: if the future rate looks clearly below today’s marginal rate, pre-tax deferrals deserve priority. If the rates could be similar or higher, split contributions so one bad forecast doesn’t control the whole plan.
A physician who started saving at 45 may still face a long accumulation period, a practice sale, or several high-income working years. Assante Wealth Management would rather leave room for those outcomes than treat one tax forecast as permanent.
The statement tells Miriam where the decision begins
Miriam starts with records, not an account slogan. She gathers the latest 401(k) statement from the plan portal, the cash balance plan statement from the administrator, and a pay stub showing year-to-date wages and deferrals.
Her tax folder supplies Form W-2, including the prior-year FICA wages used for the 2026 catch-up rule. The plan election page shows whether Roth and pre-tax sources are available and how payroll applies each election.
A Social Security estimate and a retirement-date income estimate are planning inputs, not promises. Assante Wealth Management also checks beneficiary records, because a contribution choice is incomplete if the account instructions are stale.
The first practical check is whether the proposed amount is a regular deferral or a catch-up. They use different limits and, for some high earners, different tax treatment.

“Pre-tax always wins at a doctor’s salary”
A pre-tax contribution reduces current taxable wages, while a Roth contribution pays tax now and can provide tax-free qualified distributions later. A high salary makes the current deduction valuable, but it doesn’t prove that every future dollar will face a lower rate.
The IRS lists a 37 percent top federal income tax rate for 2026 above $640,600 for single filers and $768,700 for married couples filing jointly. That threshold is not Miriam’s tax rate on every dollar; marginal income, filing status, deductions, and other income determine the actual result.
Direct Roth IRA income limits don’t apply to Roth 401(k) contributions. Traditional 401(k) balances generally face required minimum distributions beginning at turning 73, or 75 for people born in 1960 or later. That future income can stack on Social Security, practice proceeds, or other taxable sources.
Following the generic advice that every high-income doctor should put every dollar pre-tax can leave no tax-diversified source when a practice sale or law change makes later rates less favorable. The cost is not visible on payday. It appears when every income draw comes from taxable accounts.
“Roth money is locked away until retirement”
Roth 401(k) money isn’t automatically unusable before retirement, but access depends on plan terms, distribution rules, taxes, and possible penalties. Check the plan’s procedures before treating the balance as an emergency reserve.
Roth 401(k) balances aren’t subject to lifetime required minimum distributions for the owner, although the plan may still require specific distribution and rollover steps. That can simplify later income planning, but it doesn’t make the account a substitute for cash.
A physician with unstable practice income or uncertain health may hold a separate cash reserve so a bad month never forces a withdrawal from either 401(k) source. Assante Wealth Management sizes that reserve at the same meeting where we run the tax comparison.
Hypothetical: the plan letter changes the choice
Hypothetical: Miriam, 58, receives a letter from her private-group plan administrator. It says her prior-year FICA wages from that employer exceeded $150,000, so her 2026 catch-up contributions must be Roth. The letter also shows $24,500 available for regular employee deferrals, and those ordinary deferrals still share the $24,500 limit.
At an assumed 37 percent marginal federal rate, a $24,500 pre-tax deferral produces this calculation: $24,500 x 37 percent = $9,065 of current federal tax reduction. A $24,500 Roth deferral produces $0 of current federal tax reduction, but the full contribution enters the Roth source after current tax.
Now hold the contribution at $24,500 and ignore growth, deductions, and state tax. If Miriam later pays 22 percent federal tax on pre-tax money, the calculation is $24,500 x 22 percent = $5,390. At 32 percent, it is $24,500 x 32 percent = $7,840. At 37 percent, it is $24,500 x 37 percent = $9,065. A qualified Roth distribution has $0 federal income tax.
The table uses one assumption: only the later marginal tax rate changes. It does not forecast investment growth or Miriam’s tax return.
If Miriam retires at 60, she may have a few lower-income years for drawing pre-tax money. Retiring at 62 keeps more earned income in the picture. Part-time work could hold her near a high marginal bracket for years. Assante Wealth Management would run all three paths and show her the tax due under each.
Her catch-up is a separate constraint. Because prior-year FICA wages exceeded $150,000, she cannot make that catch-up pre-tax under the 2026 rule. The ordinary deferral election still deserves its own decision.
| Later tax rate | Pre-tax tax due | Qualified Roth tax |
|---|---|---|
| 22 percent | $5,390 | $0 |
| 32 percent | $7,840 | $0 |
| 37 percent | $9,065 | $0 |
“The 2026 rule only affects new graduates”
The 2026 Roth catch-up requirement reaches older high earners, not only new graduates. Prior elections should be checked against the current plan notice because payroll may handle the required Roth source differently from one employer to another.
Put the dates in calendar order. Review the prior calendar year’s FICA wages when the W-2 arrives. Confirm the employer’s 2026 election mechanics before the first affected payroll. Monitor the age-50 catch-up window and the higher age-60-through-63 catch-up window. Revisit required minimum distribution exposure before turning 73, or before 75 for people born in 1960 or later.
In 2026, a 401(k) participant can defer up to $24,500 as an employee. Savers aged 50 and older can add an $8,000 catch-up, and those aged 60 through 63 can add $11,250 instead. Even with the larger catch-up, check how payroll splits your dollars between regular and catch-up contributions.
Assante Wealth Management treats the employer notice as an operating detail, not fine print. A correct tax idea can still fail if payroll sends the wrong source or the election is made after the relevant pay period.
- W-2 arrives
- 2026 payroll election
- Age 50 catch-up window
- Ages 60 through 63 catch-up window
- Before RMD age
Can I leave room for a bad retirement year?
Yes. Test three retirement ages, three later tax rates, and a 5 percent annual return assumption for illustration before making the election. A market decline can reduce both account values, health can pull retirement forward, and Congress can change tax rules after a contribution is made.
Assante Wealth Management compares retirement at 60, 62, and a later date, then checks what income comes from the practice, Social Security, the cash balance plan, and each 401(k) source. The tax comparison should also include the cost of selling investments or converting an account; before any taxable account sale or conversion, estimate the tax bill.
The choice remains reversible only in limited ways. Future payroll elections can usually change, but a past pre-tax contribution doesn’t simply become Roth without a taxable conversion. A physician with uneven income may wait on an irreversible conversion until the income year is clearer.
A simple checklist for today: identify your current marginal bracket, estimate the bracket on early retirement income, mark the catch-up rule, and keep a liquid reserve outside the 401(k). If the future rate is clearly below today’s rate, pre-tax deserves priority. If it may be similar or higher, split contributions.
This comparison cannot predict future tax law, investment returns, Miriam’s eventual income, or the value of employer plan features. Those unknowns are why Assante Wealth Management keeps the plan short enough to revise.
How Assante Wealth Management reads the election
Assante Wealth Management can organize the plan statement, pay information, tax return, retirement-date income estimate, and beneficiary records into a short comparison of Roth, pre-tax, and split contributions. The work is about showing the tax assumptions and the downside, not naming a winner in advance.
You can ask for the recommendation and its tax assumptions in writing, with room for the contribution choice to change when income, health, or law changes. Assante Wealth Management serves clients remotely by video conference and telephone, and its client minimum is $500,000 in investable assets.
Your questions about Roth vs traditional 401(k) for doctors, answered
My employer offers both Roth and traditional 401(k) contributions; should I split them if I am still paying for my children’s education?
Splitting can be sensible when education payments make cash flow uneven. A traditional contribution may reduce current taxable income, while a Roth contribution creates a future tax-free source. Review the amount you can save after tuition and debt payments, then test both choices against retirement at 60, 62, or later. Your plan’s election rules still control.
Can I change a Roth versus traditional 401(k) decision later if my health or retirement date changes?
Usually, you can change future contribution elections, but past Roth and pre-tax contributions do not simply change labels. A health change or earlier retirement may alter the tax comparison, while a law change may alter the rules. New elections can be reviewed; conversions require a separate tax calculation and may create an immediate taxable amount.
Do high prior-year wages always force every catch-up contribution into Roth?
No. For 2026, the Roth catch-up requirement applies when prior-year FICA wages from that employer exceeded $150,000, but it affects catch-up contributions, not every 401(k) contribution. Your regular employee deferrals still use the shared $24,500 limit. Check the employer’s notice and payroll election before the affected contributions begin.
Will a Roth 401(k) keep me from paying tax on every retirement dollar?
No. Roth 401(k) money can provide tax-free qualified distributions, but other retirement income may come from traditional accounts, taxable accounts, Social Security, or practice proceeds. Traditional balances generally face required minimum distributions beginning at turning 73, or 75 for people born in 1960 or later. Account mix matters.
