Why Taxes Could Be Your Biggest Retirement Risk

For decades, Americans have been told to save as much as possible in their 401(k)s, IRAs, TSPs, and other tax-deferred retirement accounts. While those accounts can be powerful wealth-building tools, many retirees are beginning to realize there's a hidden problem lurking beneath the surface:

The IRS may own more of your retirement savings than you think.

In a recent Retirement Income School interview, bestselling author David McKnight, creator of The Power of Zero, shared why taxes could become one of the biggest retirement income challenges over the next decade—and what retirees can do now to protect themselves.

The Tax Problem Most Retirees Don't See Coming

Many retirees focus on how much they've accumulated for retirement. They proudly say they've saved $1 million, $2 million, or even more.

But there's an important question that often gets overlooked:

How much of that money actually belongs to you?

If the majority of your retirement savings is sitting inside traditional IRAs, 401(k)s, 403(b)s, or TSP accounts, you haven't paid taxes on that money yet. Every dollar withdrawn in retirement could be subject to future tax rates that none of us can predict.

That's what makes retirement tax planning so important.

According to McKnight, the United States continues to face growing national debt, increasing Social Security obligations, rising Medicare costs, and significant fiscal challenges. Whether taxes rise dramatically or only moderately, retirees with large tax-deferred accounts could feel the impact.

The real concern isn't how much income you generate in retirement—it's how much you get to keep after taxes.

Understanding the "Power of Zero"

One of McKnight's most popular concepts is called the Power of Zero.

The goal is simple: create enough tax-free income streams that you can potentially operate in a 0% effective tax bracket during retirement.

That doesn't mean having no income.

It means strategically using tax-free income sources such as:

• Roth IRAs

• Roth 401(k)s

• Roth conversions

• Tax-efficient retirement income strategies

• Properly structured cash value life insurance

• Standard deduction planning

• Social Security tax management

The benefit is straightforward. If future tax rates rise, retirees with tax-free income sources are insulated from much of the impact.

As McKnight often says, if tax rates double, two times zero is still zero.

Why Roth Conversions Continue to Gain Attention

One of the most effective tools available today is the Roth conversion.

A Roth conversion allows you to voluntarily pay taxes now at today's rates in exchange for tax-free withdrawals later.

The strategy becomes especially attractive if you believe tax rates in the future could be higher than they are today.

Many retirees hesitate because they don't like the idea of paying taxes sooner than necessary. However, waiting can create a different problem.

Required Minimum Distributions (RMDs) eventually force money out of traditional retirement accounts whether you need the income or not. Those withdrawals can increase taxable income, impact Social Security taxation, and potentially raise Medicare premiums.

The question becomes: Would you rather pay taxes voluntarily while rates are relatively low, or potentially be forced to pay them later at higher rates?

The Hidden Benefits of Tax-Free Income

Most people understand that Roth income can eliminate federal income taxes on qualified withdrawals.

What many don't realize is the ripple effect tax-free income can create.

Qualified Roth distributions generally:

• Do not count toward provisional income calculations for Social Security taxation

• Do not trigger additional federal income taxes

• Do not increase IRMAA thresholds that can raise Medicare premiums

• Can provide greater flexibility when managing retirement cash flow

This creates opportunities for retirees to control income more strategically while potentially reducing taxes throughout retirement.

A Strategy Many Retirees Haven't Heard About

One of the most interesting parts of our discussion focused on Fixed Index Annuities (FIAs) and what McKnight calls Piecemeal Internal Roth Conversions (PIRC).

Historically, retirees often faced a difficult choice.

They could focus on reducing taxes through Roth conversions, or they could focus on creating guaranteed lifetime income through annuities.

Doing both effectively was often challenging.

Today, certain annuity products allow retirees to perform partial Roth conversions over time rather than converting an entire account in a single year.

This can help retirees:

• Spread tax liability across multiple years

• Avoid unnecessarily high tax brackets

• Maintain greater tax control

• Create guaranteed income solutions

• Reduce longevity risk

For retirees looking to balance tax planning with income security, this strategy can be worth exploring.

Don't Ignore Long-Term Care Planning

Another area that often gets overlooked is long-term care.

Many retirees have watched parents or family members struggle through costly long-term care events. The concern is real, but traditional long-term care insurance isn't always appealing.

That's why some retirees explore high cash value life insurance strategies that may provide access to death benefits during life for qualifying long-term care needs.

The appeal is simple.

If long-term care is needed, benefits may help cover expenses. If it's never needed, beneficiaries may still receive a death benefit.

For many families, that flexibility makes the conversation easier.

Creating a Retirement Volatility Shield

Market volatility can also create challenges during retirement.

Traditional retirement planning often relies on the "4% Rule," which suggests retirees withdraw approximately 4% annually to help their savings last.

But what happens when markets decline?

McKnight discusses a concept called the Volatility Shield.

The idea is to maintain several years of income in a separate account that can be used during market downturns.

Instead of selling investments after a market decline, retirees may have alternative income sources available while their portfolios recover.

Reducing sequence-of-returns risk can significantly improve retirement outcomes and potentially increase the sustainability of retirement income.

The Window May Not Stay Open Forever

Nobody knows exactly what future tax rates will look like.

No one can predict Congress.

No one can predict future legislation.

But what we can do is evaluate today's opportunities and determine whether they make sense within a comprehensive retirement income plan.

The current tax environment remains historically favorable compared to many periods throughout U.S. history. For retirees who want more control over future taxes, waiting may not always be the best strategy.

The key is creating a plan that balances:

• Tax efficiency

• Guaranteed income

• Market growth

• Healthcare costs

• Long-term care concerns

• Legacy planning

Retirement planning is no longer just about accumulating assets.

It's about creating income that lasts, minimizing unnecessary taxes, and helping ensure your money works as efficiently as possible throughout retirement.

If you're concerned about future tax rates, RMDs, Medicare premiums, or creating more tax-efficient retirement income, now may be the right time to evaluate your options and determine whether your current strategy is positioned for the future.
