One of the more surprising challenges retirees face isn’t market volatility. It’s taxes.
After years of saving into retirement accounts, many individuals expect their tax burden to decrease once they stop working. But in reality, retirement income can be more complex than expected. Without careful coordination, it’s possible to unintentionally move into a higher tax bracket, often referred to as “tax bracket creep.”
This isn’t usually the result of one major mistake. More often, it comes from well-intentioned withdrawals that aren’t aligned with a broader tax strategy.
The good news is that with thoughtful planning, retirees may be able to manage income more efficiently over time. One approach often discussed is the concept of “filling the bracket.” Here’s how wealth management changes as you approach retirement to leverage this strategy.
What Is Tax Bracket Creep?
Tax bracket creep occurs when income increases enough to push a portion of your earnings into a higher tax bracket.
In retirement, this can happen when multiple income sources overlap, including:
- Required Minimum Distributions (RMDs)
- Withdrawals from Traditional IRAs or 401(k)s
- Social Security benefits
- Investment income
Each additional dollar of income may be taxed at progressively higher rates depending on your bracket.
For example, withdrawing more than needed from a Traditional IRA in a single year may push part of that income into a higher bracket, resulting in a larger tax bill than anticipated.
Why It Happens More Often Than Expected
During working years, income is typically steady and predictable. In retirement, income becomes more flexible, but also more complex.
Common reasons tax bracket creep occurs include:
- Taking large withdrawals from tax-deferred accounts in a single year
- Not coordinating withdrawals across different account types
- Ignoring how Social Security benefits are taxed
- Overlooking how RMDs interact with other income
Without a plan, it’s easy to default to withdrawing from the most accessible account, often a Traditional IRA, without considering the tax impact.
The Role of Account Types in Retirement
To understand how to manage tax bracket creep, it helps to recognize how different accounts are taxed:
- Tax-deferred accounts (Traditional IRA, 401(k))
Withdrawals are generally taxed as ordinary income - Tax-free accounts (Roth IRA, Roth 401(k))
Qualified withdrawals are typically tax-free - Taxable accounts (brokerage accounts)
May generate capital gains, dividends, or interest, depending on activity
Each account type plays a different role in retirement income planning.
The key is not just having these accounts, but using them strategically.
What Is the “Filling the Bracket” Strategy?
The idea behind “filling the bracket” is to manage your taxable income so that it stays within a desired tax bracket each year.
Rather than withdrawing large amounts from tax-deferred accounts all at once, the strategy involves:
- Identifying your target tax bracket – This could be a lower or middle bracket that aligns with your long-term plan
- Taking withdrawals from taxable sources (like Traditional IRAs) up to that limit – This “fills” your bracket without exceeding it
- Using tax-free sources (like Roth accounts) for additional income needs – This allows you to meet spending goals without increasing taxable income
The goal isn’t to minimize taxes in a single year. It’s to manage them over time.
A Simplified Example
Let’s say a retiree is targeting a specific tax bracket threshold.
- They withdraw enough from a Traditional IRA to reach, but not exceed, that threshold
- Additional income needed for expenses comes from a Roth IRA
Because Roth withdrawals are generally not taxed, they don’t push the retiree into a higher bracket.
Over time, this approach may help:
- Smooth taxable income
- Reduce the impact of higher tax brackets
- Maintain flexibility as income needs change
This is a simplified example, and real-world scenarios often involve additional variables, but the concept remains consistent.
Why This Strategy Can Be Valuable
“Filling the bracket” is not about avoiding taxes altogether. It’s about being intentional with how income is structured.
Potential benefits may include:
- More predictable tax outcomes year to year
- Greater control over retirement income
- Reduced likelihood of unexpected tax spikes
- Flexibility in adjusting withdrawals as needed
This approach can be particularly useful in years before RMDs begin, when retirees often have more control over income timing.
The Importance of Tax Diversification
This strategy works best when retirees have access to multiple account types.
If all assets are concentrated in tax-deferred accounts, options may be limited. But with a mix of traditional accounts, Roth accounts, and taxable investments, retirees may have more flexibility in how income is generated.
Tax diversification doesn’t eliminate taxes, but it can create choices.
Common Mistakes to Avoid
Even with good intentions, a few missteps can make tax bracket creep more likely:
Withdrawing Too Much from One Source
Relying heavily on a Traditional IRA in a single year can push income higher than expected.
Ignoring the Timing of Social Security
Social Security benefits may be partially taxable depending on total income, which can interact with other withdrawals.
Waiting Until RMDs Begin
Once RMDs start, flexibility decreases. Planning earlier may provide more options.
Not Reviewing the Plan Annually
Tax brackets, income needs, and regulations can change. Regular reviews help keep strategy aligned.
The Bigger Picture: It’s About Coordination
Tax bracket management isn’t a standalone tactic. It’s part of a broader financial plan.
It often intersects with:
- Investment strategy
- Retirement income planning
- Social Security timing
- Estate planning
When these elements are coordinated, income decisions tend to become more intentional.
Why This Matters for Long-Term Planning
Taxes don’t just affect one year. They affect how long your assets last.
Managing tax bracket creep may help:
- Preserve more of your retirement savings
- Support sustainable income over time
- Reduce uncertainty in future planning
Rather than reacting each year, proactive planning may allow for more control.
Bringing It All Together
Tax bracket creep is a common, but often avoidable, challenge in retirement.
By understanding how different income sources are taxed and using strategies like “filling the bracket,” retirees may be able to structure income more efficiently over time.
The goal isn’t to eliminate taxes. It’s to align them with your broader financial plan.
