Roth, Traditional, HSA or Taxable: Which Account Wins for Pre-Retirees?

Traditional, Roth, HSA, or taxable account – which maximizes after-tax income and legacy?

Now that I’m mostly retired and have most of our nest egg in traditional tax-deferred accounts, I find myself wondering if I made a mistake.

With Required Minimum Distributions (RMDs) looming, will those decades of tax deferral come back to haunt me?

We did maximize our Health Savings Account (HSA), but should I have put less into tax-deferred accounts and more into Roth or taxable instead?

Let’s compare four account types so you can decide which one really wins for you.

What Does It Mean for a Retirement Account to Win? 5 Criteria

For pre-retirees, here are the criteria I find most important:

1. Flexibility before retirement (e.g., convertibility)
2. After-tax retirement income
3. Maximum amount allowed to be invested, including income limits (if any)
4. Limitations on penalty-free and/or tax-free withdrawals
5. Tax treatment for spousal and non-spousal heirs

As we’ll see below, every account is a trade between tax timing, flexibility, and legacy efficiency. Thus, different account types “win” in different circumstances and by different criteria.

How Traditional, Roth, HSA and Taxable Accounts Are Taxed

Here’s a quick reference guide for the tax characteristics of the different account types.

Next, let’s dig a little deeper into each account type.

Traditional IRAs and 401(k)s: Deduct Now, Pay Taxes and Take RMDs Later

Both of these are tax-deferred retirement accounts. The IRA is an individual plan available to anyone with earned income, while the 401(k), along with its cousins, the 403(b) and 457 plans, are employer plans to the benefit of employees.

Since the 403(b) and 457 are limited to employees of state and local governments, religious organizations, public schools, and non-profit organizations, we’ll ignore them here.

2026 Annual Contribution Limits

• IRAs: $7,500, plus $1,100 catch-up for people over age 50.
• 401(k) plans: $24,500 elective salary deferral, plus $8,000 catch-up for employees over age 50. Employers are allowed, but not required to, match employee contributions. However, the overall contribution may not exceed the lower of 100% of the employee’s compensation or $72,000 ($80,000 if over age 50 and $83,250 if aged 60-63).
• Note that these limits are shared with the Roth versions of the same account types.

Income Limits to Contribute

None.

2026 Deductibility Limits

• For IRAs, there is a complex set of deductibility limits, depending on your filing status and whether or not you and/or your spouse have access to an employer retirement plan. For example, if married and filing jointly, and you have access to an employer plan, you can fully deduct up to a Modified Adjusted Gross Income (MAGI) of $129,000. For MAGI above $149,000, none of your contributions are tax-deductible. For MAGI between the two numbers, you can deduct a prorated fraction of the contribution. If neither you nor your spouse (if married) can access an employer plan, the deductibility of your contributions isn’t subject to income limits.
• There are no deductibility limits for employee contributions to 401(k) plans (up to the contribution limit). Employer contributions are deductible to the employer, up to 25% of employee compensation.

Withdrawal Rules

• Taxed as ordinary income in the year of the withdrawal.
• With limited exceptions, withdrawals before age 59½ are subject to a 10% penalty in addition to taxes.
• RMDs apply (if not already subject to RMDs, RMDs begin at age 73 for those who turn 73 before 2033; those who turn 73 in 2033 or later will be subject to RMDs from age 75).

Rules for Heirs

Inheritance rules are different for spouses and non-spouse heirs.

• Spouses:
• If the original account holder had already started RMDs, their widow(er) can (a) keep the account as an inherited account and delay their distributions until the original account holder would have turned 72; (b) take distributions based on their own life expectancy; or (c) follow the 10-year rule, wherein they must drain the account within 10 years of the original account holder’s death. Alternatively, the widow(er) can roll the account over into their own IRA.
• If RMDs had not been started, the widow(er) can keep the account as an inherited account and take distributions based on their own life expectancy, or roll it over into their own IRA.
• Non-spousal heirs:
• If an “eligible designated beneficiary” (for non-spouse, this is a minor child of the original account holder, disabled or chronically ill, or someone who is no more than 10 years younger than the original account holder), can (a) take distributions over the longer of their own life expectancy or the original account holder’s remaining life expectancy, or (b) follow the 10-year rule.
• If not an eligible designated beneficiary, must follow the 10-year rule.

Pros for Pre-Retirees

Get tax deductions during peak earning years.

Cons for Pre-Retirees

• RMDs apply.
• Withdrawals get stacked as taxable income on top of wage income and realized short-term capital gains, all subject to the high rates of taxes on regular wages. This may push you high enough to be subject to Medicare Income-Related Monthly Adjustment Amount (IRMAA).
• Non-spousal heirs must drain the account within 10 years and pay regular wage tax rates on the resulting withdrawals.

Roth IRAs and Roth 401(k)s: Pay Taxes Now, Withdraw Tax-Free Later

These are similar to the traditional accounts mentioned above, but instead of getting a tax deduction now and paying taxes later, you contribute after-tax dollars, and withdrawals are tax-free (once the account has been open for five years).

2026 Annual Contribution Limits

• IRAs: Share limit with traditional IRAs.
• 401(k) plans: Share limits with traditional 401(k) plans.

Income Limits to Contribute

• Complex income limits for Roth IRAs – for example, if married and filing jointly, MAGI up to $236,000 allows Roth contributions. MAGI above $246,000 disallows it. MAGI between those allows a prorated reduction in contribution limits.
• Can convert from traditional to Roth. Note that the IRS uses a pro-rata rule for the total balance of after-tax vs. pre-tax balances across all IRAs when calculating what part of the conversion is not taxable.
• Can make “back-door” contributions by making an after-tax contribution to a traditional IRA, then converting to a Roth. The pro-rata rule applies here too.
• None for 401(k).

Deductibility Limits

Not deductible.

Withdrawal Rules

• Tax-free withdrawals.
• Withdrawal of contributions is allowed, but you cannot later reverse it.
• With limited exceptions, withdrawals of earnings before age 59½ and/or before the account is five years old are subject to a 10% penalty.
• RMDs don’t apply.

Rules for Heirs

Generally, the same rules as for non-Roth accounts, except that withdrawals are tax-free, However, withdrawals of earnings from accounts that are less than five years old may be subject to income tax. Since the 10-year rule doesn’t require withdrawals in any specific year, the heir can hold off on withdrawals until the Roth account is five years old, and thus avoid such taxation.

For qualified employer plans, such as a 401(k), there are further rules.

Pros for Pre-Retirees

• Tax-free retirement income.
• Heirs receive tax-free.
• If tax rates are lower now than later, can pay lower tax now to avoid higher tax later.
• No RMD

Cons for Pre-Retirees

• No current tax deduction, potentially at a high tax bracket.
• Higher taxes now may mean current cash flow doesn’t allow maxing the contribution limits.
• Conversions cause a taxable income spike, possibly causing IRMAA.

HSAs: A Triple Tax Advantage With a Catch for Heirs

These are intended to provide a way to cover qualified healthcare expenses with pre-tax dollars. These accounts enjoy a triple tax benefit:

• Tax deduction for contributions.
• Tax-free growth.
• Tax-free withdrawals (for qualified health-related expenses).

As a result, these can be used as a long-term way to maximize healthcare dollars for retirement.

2026 Annual Contribution Limits

Assuming you have an HSA-compliant high-deductible health plan (HDHP), you can contribute up to $4,400 for an individual or $8,750 for a couple or family.

Income Limits to Contribute

None.

Deductibility Limits

Fully deductible (assuming HSA-compliant health plan).

Withdrawal Rules

• Tax-free withdrawals for qualified health-related expenses.
• After age 65, can use like a traditional IRA for non-health expenses.
• RMDs don’t apply.

Rules for Heirs

• Spouses: inherit as HSA.
• Non-spousal heirs: taxed for full market value in the year of inheritance. This means, for example, an inherited $200,000 HSA could add $200,000 of taxable income to your child in a single year, potentially pushing them up into an extremely high tax bracket.

Pros for Pre-Retirees

• Current tax deduction.
• Tax-free way to fund healthcare expenses in retirement.
• No RMD

Cons for Pre-Retirees

• Must be enrolled in HDHP.
• Penalties apply for withdrawals not used to cover eligible health-related expenses before age 65.
• Worst tax setup for non-spousal heirs.

Taxable Brokerage Accounts: Maximum Flexibility and a Step-Up in Basis

This is the least tax-efficient for you, but more tax-efficient for your heirs than a traditional retirement account, and especially compared to an HSA.

Annual Contribution Limits

None.

Income Limits to Contribute

None.

Deductibility Limits

Not deductible.

Withdrawal Rules

None.

Rules for Heirs

Heirs enjoy a step-up in basis, which means no taxes are ever due on gains that were unrealized as of the death of the original account owner.

Pros for Pre-Retirees

• When used for retirement income, (long-term) realized capital gains are taxed at the preferred long-term capital gains rates (0%, 15%, or 20%, depending on your taxable income).
• Greatest flexibility.
• Heirs receive with step-up basis.
• No RMD

Cons for Pre-Retirees

• No current tax deduction, potentially at a high tax bracket.
• Dividends and interest are taxed in the current year.
• Mutual funds distribute capital gains annually, increasing current-year taxes.

Traditional vs. Roth vs. HSA vs. Taxable: Side-by-Side Comparison

Here’s a quick summary of the four account types with their pros and cons.

My Personal Math: Comparing After-Tax Results When Cash Flow Is Limited

Numbers clarify trade-offs better than theory. Here’s how the math worked in our case.

Whenever I had an HDHP, I maxed out our HSA contributions.

Beyond that, I maxed out our traditional, tax-deferred contributions to the best of our ability, given our cash flow each year.

Let’s see how that math works when your contribution is limited by cash flow. Say you can set aside $3,350 a year and pay a total marginal tax rate of 30%. That translates to contributing $5000 into your HSA or traditional retirement account and getting a tax deduction worth $1,500, or putting $3,500 into a Roth or into your taxable account.

• Putting $5,000 in an HSA: Fits within your after-tax cash flow, grows tax-free, and allows tax-free withdrawals for qualified health expenses. Assuming 7% real (inflation-adjusted) return, you’ll have about $10,000 in 10 years, all of which is accessible for use.
• Putting $5,000 into a traditional retirement account: Fits within your after-tax cash flow, grows tax-deferred, and allows penalty-free withdrawals after age 59½ (some exceptions allow earlier penalty-free withdrawals). Assuming 7% real (inflation-adjusted) return, you’ll have about $10,000 in 10 years, but if you’re still paying 30% marginal tax rate, only $7,000 is accessible for use.
• Putting $3,500 into a Roth account: Fits within your after-tax cash flow, grows tax-free, and allows tax-free withdrawals once the account is at least five years old and you’re 59½ (contributions can be withdrawn earlier). Assuming 7% real (inflation-adjusted) return, you’ll also have about $7,000 in 10 years, all of which is accessible for use.
• Putting $3,500 into a taxable account: Fits within your after-tax cash flow, dividends and interest are taxed annually, and capital gains are taxed when realized. Realized long-term capital gains are taxed at preferred rates (0%, 15%, or 20%, depending on your taxable income). Assuming 7% real (inflation-adjusted) return, you’ll have less than $7,000 in 10 years (if you had to pay annual income taxes from dividends and interest income), and the accessible amount is even lower due to taxes on realized capital gains.

Had we not been limited by cash flow, maxing out Roth contributions would have provided more retirement income than traditional retirement accounts. Had we made the contributions to a traditional account and used the tax benefit to fund a taxable investment, the difference would shrink, but not disappear.

From the perspective of eventual heirs, we need to drain our HSA before touching our Roth accounts, and preferably before draining our tax-deferred accounts. Once the HSA is drained, we should drain as much as possible of our tax-deferred accounts before draining our taxable portfolio.

However, I don’t plan to let the bequest tail wag the retirement-income/tax dog. Accordingly, we will use our HSA in years when our taxable income is higher, and when we have little taxable income, we’ll “fill” the 12% federal tax bracket by converting a portion of our tax-deferred balance into a Roth account.

Which Account Type Wins for Your Priorities?

Pre-retirees need to balance their priorities and risks. These include:

• Current marginal tax rate (federal, state, and local).
• Expected marginal tax rate in retirement, especially once RMDs hit.
• IRMAA risk, especially once RMDs start growing.
• Estate goals.
• Current liquidity needs.

Your winning option depends on your priorities and which risks most concern you.

If your top priority is maximizing after-tax retirement income, your winning strategy is maximizing HSA contributions, if you’re eligible, up to the point where your balance is more than you’re likely to spend on qualified healthcare expenses during your lifetime.

Next, if your tax rate in retirement is likely to be equal to or higher than your current rate, Roth accounts win. If not, traditional retirement accounts are better.

If your top priority is managing RMD risk and/or funding healthcare costs, HSAs are once again your top winner, followed by Roth accounts and a taxable portfolio.

For the greatest flexibility, a taxable portfolio is your best bet.

If your priority is ensuring your heirs get the biggest benefit, Roth accounts are the clear winners, followed by traditional retirement accounts.

In short, If all else is equal and used optimally:

1. HSA wins for healthcare dollars.
2. Roth wins for legacy (e.g., $1 million inherited by non-spouse taxed at a total 33% rate in a traditional IRA is worth $670k vs. $1 million in a Roth is worth $1 million) and RMD control.
3. Traditional wins if current tax rate > retirement tax rate.
4. Taxable wins for flexibility.

How Financial Advisors Approach Tax Diversification Across Account Types

I asked several financial advisors for how they advise their clients, and the biggest mistakes they see people making when saving for retirement. Here’s what they had to say.

Alex Bridges, CFP®, ChFC®, RICP®, Wealth Advisor, Tiverton Wealth, says:

Anthony Ferraiolo, CFP®, Partner Advisor at AdvicePeriod, agrees and expands:

Ben Simerly, CFP®, Founder and Financial Advisor of Lakehouse Family Wealth, rounds out the conversation:

The Bottom Line: Tax Diversification Beats Any Single Account Type

So, did I make a mistake that will come back to haunt me?

Tentatively, my answer is that I didn’t.

True, having such a concentrated bet on tax-deferred accounts does reduce our flexibility in any specific year. For example, anytime we have an especially high spend in retirement, we’ll need to account for the higher taxes we’ll be hit with.

However, while I didn’t dig in deeply enough ahead of time to make the most informed choices, overall, I don’t regret what we did because it ended up allowing us to make the most of what our cash flow allowed us to set aside.

More generally, what I learned is that there is no perfect account type. There is only a tax structure that fits your stage of life, and managing your tax brackets over time. And the earlier you understand the trade-offs, the fewer regrets you’ll suffer.

In the end, the real winner isn’t one account type, but rather tax diversification across the account types that fit your priorities.
