Case Study: The Household That Used Retirement Strategy to Improve Tax Flexibility
By Dr. Jose G. Cardenas | Chief Tax Strategist, The C & R Group, LLC
Mark and Lisa thought they were doing everything right.
They were saving consistently.
They had strong retirement accounts.
They were earning good incomes.
And they were contributing heavily to their workplace retirement plans.
On paper, they looked prepared.
But when they reviewed their retirement strategy, one problem stood out:
Almost every retirement dollar they had accumulated would eventually be taxed the same way.
Most of their savings were in Traditional retirement accounts.
That gave them useful tax deductions during their working years.
But it also meant much of their future retirement income could eventually come from taxable distributions.
Their problem was not a lack of savings.
It was a lack of tax flexibility.
A strong retirement plan should give you choices about where income comes from—not force every retirement dollar through the same tax door.
Meet Mark and Lisa
Mark is 55.
Lisa is 52.
Together, they earn approximately:
$290,000 per year.
Their retirement assets include:
$850,000 in Traditional 401(k) accounts
and only about:
$45,000 in Roth assets.
They also maintain taxable savings and a healthy emergency reserve.
Their first instinct is to continue putting every available retirement dollar into Traditional accounts because the current-year deduction feels valuable.
And in a high-income year, that can make sense.
Traditional 401(k) contributions generally reduce current federal taxable income, while distributions are generally taxed later when withdrawn.
But the household begins asking a different question:
What happens if nearly all of our retirement income is taxable later?
That changes the conversation.
The Problem Was Tax Concentration
Mark and Lisa had done a good job diversifying investments.
They owned different funds.
Different asset classes.
Different sectors.
But from a tax perspective, the portfolio was heavily concentrated.
Most of the retirement assets sat in one tax category:
tax-deferred.
That meant future retirement income could include:
Traditional 401(k) withdrawals,
Social Security,
and possibly other taxable income.
The household did not know exactly what future tax rates would be.
No one does.
But they did know one thing:
Having only one tax bucket would give them fewer options.
That was the problem they decided to solve.
They Did Not Abandon Traditional Contributions
This is important.
The strategy was not:
“Traditional is bad. Move everything to Roth.”
That would be too simplistic.
Mark and Lisa were still having a high-income year.
The current deduction from Traditional contributions remained valuable.
For 2026, employees can generally defer up to $24,500 into a 401(k), 403(b), governmental 457(b), or TSP, with higher catch-up amounts available to eligible older workers.
So they kept part of their contributions Traditional.
But they stopped treating Traditional as the automatic answer for every dollar.
They Added Roth on Purpose
The next step was to direct part of their future contributions into Roth.
Roth contributions do not provide the same current-year deduction.
But qualified Roth distributions can generally be tax-free later. Roth IRAs also do not require lifetime minimum distributions for the original owner.
That made Roth useful for a different reason.
Not because it was automatically better.
Because it created another future income source with a different tax treatment.
Instead of having almost everything taxed later, they began building a second bucket.
Now the household could eventually choose between:
taxable Traditional withdrawals,
qualified Roth withdrawals,
and taxable investment assets.
That is tax diversification.
Then They Reviewed Their IRA Options
Mark and Lisa also reviewed whether IRAs made sense.
For 2026, taxpayers can generally contribute a combined total of up to $7,500 across Traditional and Roth IRAs, or $8,600 if age 50 or older, subject to compensation and income rules.
Because their income was relatively high, Roth IRA eligibility and Traditional IRA deductibility required careful review.
The point was not simply to open another account.
It was to understand where additional dollars could create the most value.
Retirement planning became less about:
“Where can we put more money?”
and more about:
“What tax treatment do we want this money to have later?”
Their Strategy Became a Blend
By year-end, Mark and Lisa settled on a more balanced approach.
They continued using Traditional workplace contributions for part of their savings.
They added Roth contributions for another portion.
They maintained taxable investments for liquidity.
And they kept the tax reserve and emergency fund intact.
They did not maximize every account at the expense of cash flow.
They did not convert everything to Roth.
They did not chase a single tax strategy.
They built flexibility.
That was the win.
Why Flexibility Matters in Retirement
Imagine Mark and Lisa reach retirement and need an extra:
$30,000
for a major home repair.
If nearly all their assets are Traditional, pulling that money out may increase taxable income.
But if they have multiple account types, they may have more choices about where that cash comes from.
The same idea applies when managing:
large purchases,
unexpected expenses,
travel,
charitable giving,
or years when taxable income is already high.
Tax diversification does not guarantee lower taxes.
What it can provide is more control.
And control is valuable.
A Better Way to Measure Retirement Success
Most retirement discussions focus on one number:
the account balance.
Mark and Lisa learned to watch another number too:
How much of the portfolio is available under different tax treatments?
A $1 million retirement portfolio that is entirely tax-deferred is different from a $1 million portfolio divided among:
Traditional,
Roth,
and taxable assets.
The balances may be identical.
The future tax flexibility may not be.
That is why retirement planning should look beyond accumulation.
Their Five-Part Strategy
Mark and Lisa’s year-end review ultimately centered on five decisions:
Keep some Traditional contributions for current tax relief.
Add Roth contributions to increase future tax flexibility.
Maintain taxable assets for liquidity.
Avoid sacrificing emergency cash or tax reserves just to maximize retirement contributions.
Review the strategy annually as income and retirement goals change.
Nothing about the strategy was extreme.
That is exactly why it worked.
Final Thought
Mark and Lisa did not discover a secret investment.
They did not need a complicated new product.
They simply stopped treating every retirement dollar the same.
Their biggest improvement was moving from:
tax deferral only
to
tax diversification.
The goal of retirement planning should not be to eliminate taxes completely. It should be to create enough flexibility that taxes do not control every retirement-income decision.
Traditional accounts gave them value today.
Roth accounts gave them another option for tomorrow.
Taxable assets preserved liquidity.
Together, those pieces created a more flexible retirement strategy.
