For years, retirees have been taught a simple rule of thumb for generating income:
Spend taxable assets first, then draw from traditional IRAs and 401(k)s, and leave Roth accounts for last.
It’s clean. It’s easy to remember. And in some cases, it works just fine.
But like many rules of thumb in financial planning, it starts to break down when you look at the full picture, especially when taxes, Required Minimum Distributions, Medicare premiums, and long-term planning come into play.
The reality is this:
The most effective retirement income strategy is often not about following a fixed withdrawal order. It’s about coordinating withdrawals across all account types over time.
Why the “Taxable First” Rule Became Popular
The traditional sequence didn’t come out of nowhere. It’s grounded in logic.
Taxable accounts do not have the same tax-deferral benefits as retirement accounts, so many retirees spend those first. Traditional IRAs and 401(k)s can continue growing tax-deferred. Roth accounts can continue growing tax-free, making them especially attractive to preserve.
On the surface, that makes sense.
And for a long time, that’s how many planners, and most consumers, approached retirement withdrawals.
But that approach is focused primarily on what looks best today, not necessarily what works best over a 20 or 30-year retirement.
The Problem: It Can Create Bigger Tax Issues Later
Following a rigid “taxable first” strategy can unintentionally create problems down the road.
By delaying withdrawals from IRAs, those balances may continue to grow. That can lead to larger Required Minimum Distributions later in retirement. Those larger RMDs can push retirees into higher tax brackets, increase the taxation of Social Security benefits, or trigger higher Medicare Part B and Part D premiums through IRMAA.
It can also mean missing valuable planning opportunities.
Early retirement years, especially after someone stops working but before Social Security and RMDs begin, can be a tax-planning sweet spot. If those years are spent entirely from taxable accounts, the retiree may miss the opportunity to take IRA withdrawals or do Roth conversions at relatively low tax rates.
In other words, the strategy that minimizes taxes this year may not minimize taxes over a lifetime.
A Better Question Than “Which Account First?”
More recent retirement income research, and real-world planning experience, points to a more nuanced approach.
Instead of asking, “Which account should I spend first?”
The better question is, “How should I coordinate taxable, tax-deferred, and tax-free accounts over time?”
This does not mean taking the exact same amount from each account every year. It means being intentional about the mix.
Some years, it may make sense to take more from taxable accounts. In other years, it may make sense to take IRA withdrawals, complete partial Roth conversions, or use Roth assets to avoid pushing income over a key tax threshold.
The goal is not just minimizing taxes in a single year.
It is managing tax brackets, Medicare thresholds, future RMDs, and flexibility across the entire retirement timeline.
A Simple Client Example
Consider a retiree who stops working at 62 but plans to delay Social Security until age 70.
For several years, their taxable income may be unusually low. Under the conventional rule of thumb, they might live almost entirely from taxable savings during that period and leave their IRA untouched.
At first glance, that seems sensible. They are preserving the IRA’s tax deferral and allowing their Roth assets to continue growing tax-free.
But it may not be the best long-term answer.
Those lower income years may be an ideal opportunity to intentionally take some IRA withdrawals or complete partial Roth conversions while the retiree is still in a relatively low tax bracket.
By doing so, they may reduce future RMDs, lower the risk of higher Medicare premiums later, and create more tax-free flexibility through Roth assets.
The “right” answer is not simply which account to use first.
It is how to use each account over time.
Why Many Planners Still Use the Conventional Approach
Even though this more nuanced approach is widely discussed in retirement income research, many planners still default to the traditional sequence.
Why?
Because it is simple.
It is easy to explain. It is easy to implement. And it avoids the complexity of annual tax planning.
But retirement income planning is not a one-time decision. It is an ongoing process.
The best withdrawal strategy in year one of retirement may not be the best strategy in year five, year ten, or year twenty.
Tax laws change. Markets change. Spending needs change. Health care costs change. A spouse may pass away, causing the surviving spouse to move into a less favorable tax filing status.
A rigid withdrawal order cannot account for all of that.
The Software Problem
There is another reason many retirees and planners fall back on rules of thumb:
Without the right software, it is extremely difficult to do the initial and ongoing analysis required.
A coordinated withdrawal strategy requires projecting:
- Taxable income
- IRA balances
- Roth balances
- RMDs
- Social Security taxation
- Medicare premium thresholds
- Capital gains
- Roth conversion opportunities
- Survivor tax implications
That is not something most people can do accurately with intuition or a simple spreadsheet.
The challenge is not just deciding where this year’s income should come from. It is understanding how today’s withdrawal decision affects taxes, account balances, and flexibility many years into the future.
Without robust planning software, most advisors and individuals simply cannot model the different combinations well enough to determine an optimal or near optimal strategy.
So, they often revert to the familiar rule: Taxable first. IRA second. Roth last. Not because it is always best, but because it is manageable.
The Real Goal of Retirement Income Planning
Good retirement income planning is not about blindly following a fixed sequence.
It is about controlling the tax character of income year by year.
That may mean drawing from taxable assets in one year, taking IRA distributions in another, doing partial Roth conversions during low-income years, or using Roth funds strategically to avoid a tax spike.
The best approach depends on the retiree’s age, income needs, account balances, tax bracket, Social Security strategy, estate goals, health care situation, and future RMD exposure.
There is no universal withdrawal order that works for everyone.
Final Thought
Rules of thumb have their place. They simplify complex decisions and give people a starting point.
But retirement income planning is too important to leave to a shortcut.
The old taxable first rule may work in some cases, but it can miss the bigger picture. A more effective strategy often involves coordinating withdrawals from taxable, tax-deferred, and tax-free accounts in a way that manages taxes over the full retirement timeline.
The question is not just: Which account should I use first?
The better question is: What combination of accounts gives me the best long-term result?
That answer requires analysis, planning, and ongoing adjustments.
And increasingly, it requires moving beyond rules of thumb and using the right tools to make better retirement income decisions.
Retirement Withdrawal Strategy: Common Questions
What is the best order to withdraw retirement accounts?
The best order depends on your tax situation. A common rule is taxable accounts first, then traditional IRAs, then Roth IRAs. But many retirees may benefit from coordinating withdrawals across all account types to manage taxes over time.
Should I always withdraw from taxable accounts first in retirement?
No. Withdrawing only from taxable accounts first can increase future IRA balances and lead to larger Required Minimum Distributions. Some retirees may benefit from IRA withdrawals or Roth conversions during lower-income years.
Is it better to withdraw from an IRA or taxable account first?
It depends on your current and future tax brackets. IRA withdrawals may make sense in low-income years. Taxable withdrawals may make sense when you want to avoid increasing taxable income.
When should I withdraw from my Roth IRA?
Roth IRA withdrawals are often saved for later retirement because they are tax-free. But Roth funds can also be used strategically to avoid higher tax brackets, Medicare premium surcharges, or large tax bills.
What is the most tax-efficient retirement withdrawal strategy?
The most tax-efficient strategy usually coordinates taxable, tax-deferred, and Roth accounts. The goal is to manage taxable income each year and reduce lifetime taxes, not simply follow one fixed withdrawal order.
Should I take money from multiple retirement accounts in the same year?
Often, yes. Taking money from multiple account types can help smooth taxable income and reduce the risk of larger tax bills later in retirement.
Why does retirement withdrawal strategy matter?
Withdrawal strategy affects lifetime taxes, Medicare premiums, Required Minimum Distributions, Social Security taxation, and how long your savings may last.
What are Required Minimum Distributions?
Required Minimum Distributions, or RMDs, are mandatory withdrawals from traditional retirement accounts beginning at a certain age. Larger IRA balances can mean larger taxable withdrawals later in retirement.
Should I do Roth conversions in retirement?
Roth conversions can make sense during lower-income retirement years. They may reduce future RMDs, create tax-free income later, and improve long-term tax flexibility.
Why do many advisors still use the taxable-first rule?
Many advisors use the taxable-first rule because it is simple and easy to explain. More advanced withdrawal strategies require tax projections, planning software, and ongoing analysis.
Can I figure out the best withdrawal strategy myself?
You can estimate a withdrawal strategy yourself, but optimizing it is difficult. It requires projecting taxes, RMDs, Social Security, Medicare premiums, investment returns, and future spending.
Does the best withdrawal strategy change over time?
Yes. The best withdrawal strategy can change as tax laws, markets, income needs, health care costs, and family circumstances change. Retirement income planning should be reviewed regularly.
Converting from a traditional IRA to a Roth IRA is a taxable event.
A Roth IRA offers tax free withdrawals on taxable contributions.
To qualify for the tax-free and penalty-free withdrawal or earnings, a Roth IRA must be in place for at least five tax years, and the distribution must take place after age 59 ½ or due to death, disability, or a first-time home purchase (up to a $10,000 lifetime maximum). Depending on state law, Roth IRA distributions may be subject to state taxes.
