How You Withdraw Matters as Much as How Much You've Saved
Most retirement income plans fail not because a portfolio ran out of money, but because withdrawals were taken in the wrong order, at the wrong time, from the wrong accounts. A coordinated withdrawal strategy (one built around taxes, not just balances) can meaningfully reduce what you give back to the IRS over the course of your retirement.
This page is educational in nature. For advice specific to your situation, we recommend coordinating with a qualified tax professional alongside your financial plan.
Three Buckets, and Why the Order You Draw From Them Matters
Most retirees hold assets across three types of accounts, each taxed differently. How you sequence withdrawals across them determines your tax bill year by year — and cumulatively over decades.
Taxable Accounts
Brokerage and savings accounts funded with after-tax dollars. Gains are subject to capital gains tax, but qualified dividends and long-term gains often face lower rates than ordinary income. These accounts carry no required distribution schedule.
Tax-Deferred Accounts
Traditional IRAs, 401(k)s, and similar accounts. Contributions were made pre-tax, so every dollar withdrawn is taxed as ordinary income in the year you take it. Required Minimum Distributions (RMDs) begin at age 73 and force taxable income whether you need the money or not.
Tax-Free Accounts
Roth IRAs and Roth 401(k)s. Contributions were made with after-tax dollars, qualified withdrawals are tax-free, and Roth IRAs carry no RMDs (Required Minimum Distribution) during the owner's lifetime. These accounts are among the most valuable assets in a coordinated income plan — and among the most frequently misused.
The sequencing question is not simply "which account is biggest." It is which account to draw from first, in what proportion, and in which years — to keep your taxable income in the most favorable brackets across your full retirement horizon.
The Pre-RMD Window: A Narrow Opening Worth Planning Around
For many retirees, the years between leaving work and the onset of RMDs represent a genuine planning opportunity. Income is lower. Tax brackets are more favorable. And Roth conversion — moving money from a tax-deferred account into a tax-free Roth — can be done at a lower tax cost than it will be once RMDs begin.
Once RMDs arrive, they add a floor of taxable income you cannot avoid. That floor can push additional withdrawals, Social Security income, and investment gains into higher brackets. It can trigger Medicare IRMAA surcharges — income-related premium adjustments that increase Part B and Part D costs. And it limits your flexibility to manage income in a given year.
The window before RMDs is the time to act. Converting strategically, filling lower brackets deliberately, and repositioning assets with an eye toward future tax exposure can reduce what you owe over the full arc of retirement. The math is not always straightforward, and the right approach depends on your full financial picture — which is why this coordination belongs inside a comprehensive plan, not on a spreadsheet in isolation.
How Withdrawal Sequencing Reduces Lifetime Tax Drag
There is no single correct withdrawal order for every retiree. Conventional guidance — spend taxable first, then tax-deferred, then tax-free — is a useful starting point, but it often produces a suboptimal outcome when applied without adjustment.
A coordinated approach looks at your full income picture in each year of retirement: Social Security timing, pension income, part-time earnings, investment distributions, and planned large expenses. From there, withdrawals are structured to:
- Keep taxable income within target brackets year by year
- Reduce the size of tax-deferred accounts before RMDs make them unavoidable
- Preserve Roth assets for years when tax-free income is most valuable, or for legacy transfer
- Minimize exposure to IRMAA thresholds that affect Medicare premiums
- Account for a surviving spouse's future tax situation, which often involves filing as a single taxpayer at higher rates
This is not a one-time calculation. It is an ongoing coordination between your withdrawal plan, your tax planning, and the rest of your financial strategy — reviewed as tax law, account balances, and life circumstances change.
We coordinate retirement income planning with tax planning as part of an integrated approach, so decisions made in one area account for their effects in the other.

FAQ
Frequently Asked Questions About Retirement Income Planning
Which accounts should I withdraw from first in retirement?
There is no universal answer — the right sequence depends on your tax situation, account balances, Social Security timing, and long-term income needs. A common starting point is to draw from taxable accounts first, then tax-deferred, then tax-free. But in many cases, blending withdrawals across account types in specific years produces a better tax outcome than following a strict sequence.
How does a Roth conversion work, and when does it make sense?
A Roth conversion moves money from a traditional IRA or 401(k) into a Roth IRA. You pay ordinary income tax on the converted amount in the year of conversion, but future growth and qualified withdrawals are tax-free. It tends to make the most sense when your current tax rate is lower than you expect it to be in the future — often in the years between retirement and the start of RMDs.
What are RMDs and why do they matter for tax planning?
Required Minimum Distributions are mandatory annual withdrawals from traditional IRAs and most employer retirement plans, beginning at age 73. The IRS calculates the minimum based on your account balance and life expectancy. Because RMDs are taxed as ordinary income, large balances in tax-deferred accounts can generate significant taxable income — sometimes pushing you into a higher bracket or triggering Medicare surcharges. Planning ahead of RMDs gives you more control over that outcome.
What is IRMAA and how does it affect retirement income planning?
IRMAA stands for Income-Related Monthly Adjustment Amount. It is a Medicare surcharge applied to Part B and Part D premiums when your modified adjusted gross income exceeds certain thresholds. Because IRMAA is based on income from two years prior, a large Roth conversion or an unusually high-income year can trigger higher Medicare costs unexpectedly. Coordinating withdrawals and conversions with IRMAA thresholds in mind is one of the less visible but meaningful parts of retirement income planning.
How does retirement income planning connect to the rest of my financial plan?
Withdrawal decisions affect your tax situation, your estate, your Medicare costs, and your long-term portfolio sustainability. Treating retirement income as a standalone calculation — separate from tax planning, estate planning, and investment management — tends to produce gaps. We build withdrawal strategy as part of an integrated plan, so each decision accounts for its effects across the full picture.
Ready to Model Your Withdrawal Strategy?
The difference between a coordinated withdrawal plan and an uncoordinated one is often measured in years of additional income — not percentage points. If your retirement accounts are in place but the plan for drawing from them isn't, that's worth a conversation.
