When Retirement Goes Better Than Planned: The Tax Problems of Having Too Much Money

For decades, retirement planning has centered around one question:

"Will I have enough?"

It's an understandable concern. No one wants to outlive their savings.

But after working with hundreds of retirees, we've noticed another problem that receives far less attention:

What happens when retirement goes better than expected?

Many retirees discover they saved diligently, invested wisely, spent less than anticipated, and watched their portfolios continue to grow throughout retirement. While that's certainly preferable to running out of money, it can create a new set of planning challenges.

Large retirement accounts, growing investment portfolios, and conservative spending habits often lead to higher taxes, increased Medicare premiums, and more complicated estate planning.

In other words, financial success can create tax inefficiencies if it isn't managed strategically.

Why More Money Doesn't Always Mean More Financial Flexibility

Accumulating wealth is only one part of retirement planning.

The other part is figuring out how to use that wealth efficiently.

Many retirees assume that if they don't need to withdraw money from their retirement accounts, they'll simply leave it invested. Unfortunately, the IRS has other plans.

Once Required Minimum Distributions (RMDs) begin, retirees lose much of their control over the timing of taxable withdrawals.

Even if they don't need the income, they're generally required to take distributions from traditional IRAs and many employer-sponsored retirement plans.

Those distributions can create a ripple effect across nearly every aspect of a retirement plan.

The Challenge of Large Required Minimum Distributions

For retirees with substantial tax-deferred savings, RMDs often become the biggest source of taxable income later in retirement.

What starts as a manageable annual withdrawal can grow significantly over time if investment returns outpace distributions.

Example

Mark retires at age 65 with:

• $2.8 million in traditional retirement accounts

• A paid-off home

• A pension

• Social Security benefits

He doesn't need to touch his IRA during his first several years of retirement.

By the time RMDs begin, his account has grown to more than $4 million.

Now he's required to withdraw well over $150,000 annually, regardless of whether he needs the money.

Those withdrawals increase:

• Federal taxable income

• State taxable income (where applicable)

• Medicare premiums

• Taxes on investment income

Ironically, delaying withdrawals because he didn't need the money ultimately resulted in larger taxable distributions.

Key Insight

Sometimes the biggest tax bill isn't caused by poor planning. It's caused by successful investing combined with years of deferred taxation.

Medicare IRMAA Can Turn Success Into Higher Healthcare Costs

Many retirees are surprised to learn that Medicare isn't priced the same for everyone.

Higher-income retirees pay Income-Related Monthly Adjustment Amount (IRMAA) surcharges on:

• Medicare Part B

• Medicare Part D

As retirement income increases, so do Medicare premiums.

Large RMDs are one of the most common reasons retirees unexpectedly cross into higher IRMAA brackets.

Unlike income taxes, these higher premiums often feel like an additional tax on retirement success.

Conservative Spending Can Create Bigger Tax Problems Later

Many retirees underspend because they're worried about the future.

They postpone vacations.

Delay home improvements.

Skip experiences they've always wanted.

Meanwhile, their retirement accounts continue growing.

While financial discipline is admirable, consistently spending far less than your plan allows can unintentionally increase future tax liabilities.

Example

Susan budgets $130,000 annually for retirement but only spends about $75,000 because she's afraid of running out of money.

As a result:

• Her IRA continues growing.

• Future RMDs become much larger.

• She pays more in taxes.

• Medicare premiums increase.

• She ultimately leaves a larger tax-deferred account to her children.

The money she spent decades saving may eventually be taxed at higher rates than if she had withdrawn it more strategically during retirement.

A Large Traditional IRA May Not Be the Gift You Think It Is

Many retirees view their IRA as a legacy for their children.

While those accounts can certainly provide meaningful inheritances, they also come with tax consequences.

Under current law, most non-spouse beneficiaries must fully distribute inherited retirement accounts within ten years.

For adult children in their peak earning years, those required withdrawals can push them into much higher tax brackets.

Example

A daughter earning $250,000 inherits a $1.5 million traditional IRA.

Over the next ten years, she must withdraw those funds according to current distribution rules.

Those withdrawals may be taxed at some of the highest marginal rates she'll ever pay.

Meanwhile, a Roth IRA inherited under similar circumstances may provide significantly greater tax flexibility.

Important Note

Leaving pre-tax retirement assets to heirs often transfers a future tax liability along with the inheritance.

Tax Diversification Matters Just as Much as Investment Diversification

Many retirees have diversified portfolios but not diversified tax treatment.

It's common to see wealth concentrated in:

• Traditional IRAs

• 401(k)s

• 403(b)s

While these accounts provide valuable tax deferral during working years, relying too heavily on them can reduce flexibility in retirement.

A diversified retirement income strategy may include assets held in:

• Tax-deferred accounts

• Roth accounts

• Taxable brokerage accounts

• Cash reserves

Having multiple sources of retirement income allows retirees to better manage taxable income from year to year.

Why Roth Conversions Become More Valuable

One of the best opportunities to manage future taxes often occurs before RMDs begin.

Many retirees experience several years between retirement and the start of mandatory distributions when taxable income is relatively low.

These years may provide an opportunity to convert portions of traditional retirement accounts into Roth IRAs.

The goal isn't simply to reduce taxes this year.

Instead, Roth conversions may help:

• Reduce future RMDs.

• Lower lifetime taxable income.

• Improve Medicare premium planning.

• Leave more tax-efficient assets to heirs.

• Increase flexibility when generating retirement income.

Every conversion should be evaluated within the context of the retiree's overall tax situation and long-term objectives.

The Emotional Side of Having "Too Much"

Many retirees struggle with a mindset they developed during decades of saving.

They spent their careers accumulating wealth.

Then retirement arrives, and they're suddenly expected to spend it.

That's easier said than done.

Some retirees continue saving out of habit, even when they have more than enough to support their lifestyle.

Others hesitate to enjoy experiences they've worked decades to afford because they're focused on preserving every dollar.

Financial security is important.

But retirement planning should also support the life those savings were meant to fund.

Common Mistakes Successful Retirees Make

Retirees with significant assets often make similar planning mistakes, including:

• Assuming tax-deferred always means tax-free.

• Waiting until RMDs begin before addressing taxes.

• Focusing only on investment returns instead of after-tax income.

• Ignoring future Medicare premium increases.

• Leaving large traditional IRAs to children without considering the tax burden.

• Becoming so focused on preserving wealth that they never enjoy it.

Planning Strategies for High-Net-Worth Retirees

Every situation is unique, but retirees with substantial assets should regularly evaluate strategies such as:

• Multi-year Roth conversion planning.

• Coordinating withdrawals across different account types.

• Harvesting capital gains strategically.

• Qualified Charitable Distributions (QCDs) after becoming eligible.

• Reviewing estate plans alongside tax projections.

• Modeling lifetime taxes instead of focusing only on annual tax returns.

The objective isn't necessarily to minimize taxes every year.

It's to reduce taxes over the course of retirement while creating greater flexibility for both retirees and their heirs.

More Wealth Should Create More Choices

One of the greatest benefits of financial success is flexibility.

Unfortunately, taxes can quietly reduce that flexibility if they aren't considered alongside investment performance.

Retirement planning doesn't end once you've accumulated enough assets.

In many ways, that's when some of the most important decisions begin.

At Greenbush Financial Group, we often remind clients that successful retirement planning isn't measured by the size of a portfolio. It's measured by how efficiently that wealth supports your lifestyle, your family, and your long-term goals.

Final Thoughts

Running out of money isn't the only retirement risk.

For many successful retirees, accumulating substantial wealth creates a different challenge: managing taxes, Medicare costs, Required Minimum Distributions, and legacy planning in a tax-efficient way.

With thoughtful planning, retirees may be able to reduce lifetime taxes, preserve greater flexibility, and leave a more efficient legacy for future generations. The goal isn't simply to build wealth. It's to make the most of it.

Frequently Asked Questions

1. Can you have too much money in a traditional IRA?
   While it's difficult to have "too much" money, very large traditional IRAs can lead to substantial Required Minimum Distributions and higher lifetime taxes if no planning is done.
2. Why do large RMDs increase taxes?
   Required Minimum Distributions are generally taxed as ordinary income. Larger distributions can push retirees into higher tax brackets, increase Medicare premiums, and affect other tax calculations.
3. Should wealthy retirees still consider Roth conversions?
   In many cases, yes. Roth conversions may help reduce future RMDs, improve tax diversification, and create more tax-efficient inheritances. The right strategy depends on the retiree's projected tax situation.
4. Can leaving an IRA to my children create tax problems?
   Potentially. Most non-spouse beneficiaries must distribute inherited retirement accounts within ten years under current law, which can increase their taxable income during peak earning years.
5. Is underspending in retirement a problem?
   It can be. While spending conservatively provides peace of mind, consistently underspending may lead to larger retirement account balances, higher future RMDs, and missed opportunities to enjoy retirement.
6. What's the difference between investment success and tax efficiency?
   Investment success focuses on growing assets. Tax efficiency focuses on how much of those assets you actually keep after taxes over your lifetime and how efficiently they're passed to future generations.

Claiming Social Security Early or Late: Which Age Is Right for You?

Deciding when to claim Social Security is one of the most important retirement decisions because it directly impacts your lifetime income. Claiming early at 62 reduces your benefit, waiting until full retirement age (67) provides your standard benefit, and delaying to age 70 increases your benefit significantly. At Greenbush Financial Group, our analysis shows that the right decision depends on your life expectancy, income needs, tax strategy, and overall retirement plan.

How Social Security Benefits Change by Age

Your benefit amount is based on your Full Retirement Age (FRA), which is typically 67 for those born in 1960 or later.

Benefit Adjustments by Claiming Age

• Age 62 → ~30% reduction

• Age 67 → 100% of your benefit

• Age 70 → ~24% increase from FRA

Example

If your FRA benefit is $2,000 per month:

At Greenbush Financial Group, we emphasize that this is a permanent decision that affects income for life.

Why This Decision Matters So Much

Social Security is one of the only income sources in retirement that is:

• Guaranteed for life

• Adjusted for inflation

• Not impacted by market performance

This makes it a critical foundation for retirement income planning.

When It May Make Sense to Claim at Age 62

Claiming early provides income sooner, but at a reduced level.

Situations Where Age 62 May Make Sense

• You need income to retire

• Health concerns or shorter life expectancy

• You want to preserve investment assets

• You are concerned about future policy changes

Trade-Off

• Lower monthly income for life.

At Greenbush Financial Group, we typically see this strategy used when income needs outweigh long-term maximization.

When Claiming at Full Retirement Age (67) Makes Sense

Full Retirement Age provides your standard benefit without reductions or credits.

Situations Where Age 67 May Make Sense

• You want a balanced approach

• You are still working into your mid-to-late 60s

• You want to avoid early reduction penalties

• You are unsure about delaying further

Key Advantage

• No reduction, no delay risk.

When It Makes Sense to Delay Until Age 70

Delaying increases your benefit through delayed retirement credits.

Benefits of Waiting

• Higher guaranteed monthly income

• Better inflation-adjusted income over time

• Increased survivor benefits for a spouse

Situations Where Age 70 May Make Sense

• You have longevity in your family

• You do not need income immediately

• You want to maximize lifetime income

• You are concerned about outliving your money

• You have significant Tax Deferred Assets to drawdown

At Greenbush Financial Group, delaying to 70 is often one of the most effective ways to increase guaranteed retirement income.

The Break-Even Analysis: When Do You Come Out Ahead?

A common way to evaluate this decision is through a break-even analysis.

General Insight

• Break-even age is often around 78–82

• If you live beyond this range, delaying may result in higher lifetime income

Important Note

This analysis does not account for:

• Taxes

• Investment returns

• Spousal benefits

• Personal spending needs

How Taxes Impact Your Social Security Decision

Your Social Security benefits may be taxable depending on your income.

Key Considerations

• Up to 85% of benefits can be taxable

• IRA withdrawals can increase taxation

• Claiming earlier may reduce taxable income in some scenarios

Planning Strategy

Coordinate Social Security with retirement withdrawals to manage your tax bracket effectively.

Spousal and Survivor Benefit Considerations

Married couples should evaluate this decision together.

Key Rules

• Spouse can receive up to 50% of the higher earner’s benefit

• Survivor receives the higher of the two benefits

Planning Insight

Delaying benefits for the higher earner can increase survivor income significantly.

At Greenbush Financial Group, spousal coordination is often one of the most impactful strategies.

A Simple Decision Framework

Instead of looking for a one-size-fits-all answer, consider these key questions:

Ask Yourself

• Do I need the income now?

• What is my health and life expectancy?

• Do I have other income sources?

• What is my tax situation?

• Am I planning for a spouse or survivor benefit?

Common Mistakes to Avoid

• Claiming early without a plan

• Ignoring spousal benefits

• Focusing only on break-even analysis

• Not considering taxes

• Making the decision in isolation from your full retirement plan

Final Thoughts

There is no universally “correct” age to claim Social Security. The best decision depends on your financial situation, health, and long-term goals.

At Greenbush Financial Group, our analysis shows that integrating Social Security into a broader retirement income and tax strategy leads to better outcomes than focusing on the decision in isolation.

2026 Tax-Efficient Retirement Withdrawals: How to Keep More of Your Money

A tax-efficient retirement withdrawal strategy focuses on minimizing taxes while creating consistent income throughout retirement. The order in which you withdraw from taxable, tax-deferred, and Roth accounts can significantly impact how long your money lasts. At Greenbush Financial Group, our analysis shows that strategic withdrawals can reduce lifetime taxes and increase net retirement income.

Understanding the Three Types of Retirement Accounts

Before building a withdrawal strategy, it is important to understand how different accounts are taxed.

1. Taxable Accounts (Brokerage Accounts)

• Capital gains taxes apply when investments are sold

• Long-term capital gains rates are often lower than income tax rates

• Dividends may also be taxed annually

2. Tax-Deferred Accounts (Traditional IRA, 401(k))

• Withdrawals are taxed as ordinary income

• Required Minimum Distributions (RMDs) apply starting in your 70s

3. Tax-Free Accounts (Roth IRA, Roth 401(k))

• Qualified withdrawals are tax-free

• No RMDs for Roth IRAs

• Provides flexibility for tax planning

At Greenbush Financial Group, we view these three “buckets” as the foundation of any tax-efficient withdrawal plan.

The Traditional Withdrawal Order Strategy

A common approach is to withdraw funds in a specific sequence to manage taxes over time.

Standard Withdrawal Order

1. Taxable accounts first

2. Tax-deferred accounts second

3. Roth accounts last

Why This Strategy Works

• Allows tax-deferred accounts to continue growing

• Delays ordinary income taxes

• Preserves Roth accounts for later years or legacy planning

However, this strategy is not always optimal in every situation.

Why a Blended Withdrawal Strategy May Be Better

Strictly following the traditional order can sometimes lead to higher taxes later in retirement.

The Problem

If you delay withdrawals from tax-deferred accounts too long:

• RMDs can become large

• You may be pushed into higher tax brackets

• Social Security may become more taxable

• Medicare premiums (IRMAA) may increase

A More Strategic Approach

At Greenbush Financial Group, we often recommend a blended withdrawal strategy:

• Withdraw from taxable accounts

• Supplement with partial IRA withdrawals

• Use Roth accounts strategically when needed

This helps smooth out taxable income over time rather than creating spikes later.

Roth Conversions: A Key Tax Planning Tool

One of the most powerful strategies in retirement is converting pre-tax money into Roth accounts.

How It Works

• Move funds from a Traditional IRA to a Roth IRA

• Pay taxes now at current rates

• Future growth and withdrawals are tax-free

When It Makes Sense

• Years with lower income (early retirement before Social Security)

• Before RMDs begin

• When tax rates are temporarily lower

Example

• Convert $50,000 from IRA to Roth

• Pay tax today at a lower rate

• Reduce future RMDs and taxes

At Greenbush Financial Group, Roth conversion strategies are often a cornerstone of long-term tax planning.

Managing Your Tax Bracket Each Year

Instead of focusing only on which account to withdraw from, it is often more effective to focus on your tax bracket.

Strategy

• Fill up lower tax brackets intentionally

• Avoid jumping into higher brackets

• Coordinate withdrawals with Social Security timing

Example

If the 12% tax bracket ends at a certain income level:

• Withdraw just enough from IRA to stay within that bracket

• Use Roth or taxable accounts for additional income needs

This approach allows for more control over lifetime taxes.

How Social Security Impacts Your Tax Strategy

Social Security income can change how your withdrawals are taxed.

Key Considerations

• Up to 85% of Social Security benefits can be taxable

• Additional income from IRA withdrawals can increase taxation

• Timing Social Security can impact your tax plan

Planning Insight

Delaying Social Security while using IRA withdrawals or Roth conversions early in retirement can sometimes lead to better long-term outcomes.

Avoiding Common Retirement Tax Mistakes

Many retirees unintentionally increase their tax burden.

Common Mistakes

• Waiting too long to withdraw from tax-deferred accounts

• Ignoring Roth conversion opportunities

• Triggering higher Medicare premiums (IRMAA)

• Not coordinating withdrawals with tax brackets

• Over-withdrawing in a single year

At Greenbush Financial Group, we often see that small adjustments can lead to significant tax savings over time.

A Simple Example of a Tax-Efficient Withdrawal Plan

Scenario

• Age 62, retired

• $1,000,000 in savings

  • $400,000 IRA

  • $300,000 Roth IRA

  • $300,000 brokerage

Strategy

• Withdraw from brokerage for living expenses

• Convert $30,000–$50,000 annually from IRA to Roth

• Delay Social Security until later years

• Use Roth funds strategically after RMD age

Result

• Lower lifetime taxes

• Reduced RMD impact

• Greater flexibility in retirement

Final Thoughts

A tax-efficient withdrawal strategy is not about following a fixed rule. It is about coordinating income sources, tax brackets, and long-term planning.

At Greenbush Financial Group, our analysis shows that retirees who proactively manage taxes throughout retirement often keep significantly more of their income and reduce the risk of large tax surprises later in life.

Self-Employment Income In Retirement? Use a Solo(k) Plan To Build Wealth

It’s becoming more common for retirees to take on small self-employment gigs in retirement to generate some additional income and to stay mentally active and engaged.  But, it should not be overlooked that this is a tremendous wealth-building opportunity if you know the right strategies.  There are many, but in this article, we will focus on the “Solo(k) strategy.” 

What Is A Solo(K)

A Solo(k) plan is an employer-sponsored retirement plan that is only allowed to be sponsored by owner-only entities.   It works just like a 401(k) plan through a company but without the high costs or administrative hassles.  The owner of the business is allowed to make both employee deferrals and employer contributions to the plan.

Solo(k) Deferral Limits

For 2026, a business owner is allowed to contribute employee deferrals up to a maximum of the LESSER of:
· 100% of compensation; or
· $32,500 (Assuming the business owner is age 50+) or
· $35,750 (For individuals age 60-63)

Pre-tax vs. Roth Deferrals

Like a regular 401(K) plan, the business owner can contribute those employee deferrals as all pre-tax, all Roth, or some combination of the two. Herein lies the ample wealth-building opportunity. Roth assets can be an effective wealth accumulation tool. Like Roth IRA contributions, Roth Solo(k) Employee Deferrals accumulate tax deferred, and you pay NO TAX on the earnings when you withdraw them as long as the account owner is over 59½ and the Roth account has been in place for more than five years.

Also, unlike Roth IRA contributions, there are no income limitations for making Roth Solo(k) Employee Deferrals and the contribution limits are higher. If a business owner has at least $32,500 in compensation (net profit) from the business, they could contribute the entire $32,500 all Roth to the Solo(K) plan. A Roth IRA would have limited them to the max contribution of $8,000 and they would have been excluded from making that contribution if their income was above the 2025 threshold.

A quick note, you don’t necessarily need $32,500 in net income for this strategy to work; even if you have $18,000 in net income, you can make an $18,000 Roth contribution to your Solo(K) plan for that year. The gem to this strategy is that you are beginning to build this war chest of Roth dollars, which has the following tax advantages down the road……

Tax-Free Accumulation and Withdrawal: If you can contribute $100,000 to your Roth Solo(k) employee deferral source by the time you are 70, if you achieve a 6% rate of return at 80, you have $189,000 in that account, and the $89,000 in earnings are all tax-free upon withdrawal.

No RMDs:  You can roll over your Roth Solo(K) deferrals into a Roth IRA, and the beautiful thing about Roth IRAs are no required minimum distributions (RMD) at age 73 or 75.  Pre-tax retirement accounts like Traditional IRAs and 401(k) accounts require you to begin taking RMDs at age 73 or 75 based on your date of birth, which are forced taxable events; by having more money in a Roth IRA, those assets continue to build.

Tax-Free To Beneficiaries: When you pass assets on to your beneficiaries, the most beneficial assets to inherit are often a Roth IRA or Roth Solo(k) account.   When they changed the rules for non-spouse beneficiaries, they must deplete IRAs and retirement accounts within ten years. With pre-tax retirement accounts, this becomes problematic because they have to realize taxable income on those potentially more significant distributions.  With Roth assets, not only is there no tax on the distributions, but the beneficiary can allow that Roth account to grow for another ten years after you pass and withdraw all the earnings tax and penalty-free.

Why Not Make Pre-Tax Deferrals?

It's common for these self-employed retirees to have never made a Roth contribution to retirement accounts, mainly because, during their working years, they were in high tax brackets, which warranted pre-tax contributions to lower their liability.   But now that they are retired and potentially showing less income, they may already be in a lower tax bracket, so making pre-tax contributions, only to pay tax on both the contributions and the earnings later, may be less advantageous.  For the reasons I mentioned above, it may be worth foregoing the tax deduction associated with pre-tax contributions and selecting the long-term benefits associated with the Roth contributions within the Solo(k) Plan.

Now there are situations where one spouse retires and has a small amount of self-employment income while the other spouse is still employed.  In those situations, if they file a joint tax return, their overall income limit may still be high, which could warrant making pre-tax contributions to the Solo(k) plan instead of Roth contributions.  The beauty of these Solo(k) plans is that it’s entirely up to the business owner what source they want to contribute to from year to year. For example, this year, they could contribute 100% pre-tax, and then the following year, they could contribute 100% Roth. 

Solo(k) versus SEP IRA

Because this question comes up frequently, let's do a quick walkthrough of the difference between a Solo(k) and a SEP IRA. A SEP IRA is also a popular type of retirement plan for self-employed individuals; however, SEP IRAs do not allow Roth contributions, and SEP IRAs limit contributions to 20% of the business owner’s net earned income.  Solo(K) plans have a Roth contribution source, and the contributions are broken into two components, an employee deferral and an employer profit sharing.

As we looked at earlier, the employee deferral portion can be 100% of compensation up to the Solo(K) deferral limit of the year, but in addition to that amount, the business owner can also contribute 20% of their net earned income in the form of a profit sharing contribution.

When comparing the two, in most cases, the Solo(K) plan allows business owners to make larger contributions in a given year and opens up the Roth source.

Frequently Asked Questions (FAQs):

What is a Solo(k) plan?
A Solo(k) is a 401(k)-style retirement plan designed for self-employed individuals or business owners with no employees other than a spouse. It allows both employee and employer contributions, offering high contribution limits and flexible tax options.

How much can you contribute to a Solo(k) in 2025?
For 2025, you can contribute the lesser of 100% of your compensation or up to:

• $31,000 if age 50 or older

• $34,750 if age 60–63
  These limits include employee deferrals and do not count potential employer profit-sharing contributions.

Can Solo(k) contributions be Roth or pre-tax?
Yes. You can choose to make contributions as pre-tax, Roth, or a combination of both. Roth contributions are made with after-tax dollars but grow tax-free, and qualified withdrawals are also tax-free.

Why might Roth Solo(k) contributions be advantageous for retirees?
Roth Solo(k) assets grow tax-free, have no required minimum distributions (RMDs) once rolled into a Roth IRA, and can be passed to beneficiaries without income tax. For retirees in lower tax brackets, contributing to Roth accounts may provide long-term tax benefits over pre-tax deferrals.

Can you make Roth contributions to a SEP IRA?
No. SEP IRAs only allow pre-tax contributions and do not offer a Roth option. This makes the Solo(k) plan a more flexible choice for self-employed individuals looking to build tax-free retirement income.

How does a Solo(k) compare to a SEP IRA?
A Solo(k) allows both employee deferrals (up to 100% of income) and employer profit-sharing contributions, plus the option for Roth contributions. A SEP IRA limits contributions to 20% of net earned income and only allows pre-tax contributions, typically resulting in lower total contribution potential.

Is a Solo(k) a good option for retirees with part-time income?
Yes. For retirees earning even modest self-employment income, a Solo(k) can be a powerful tool to continue saving for retirement—especially with Roth contributions that provide future tax-free income and estate planning advantages.
