How to Pay Less Tax in Retirement: The Optimal Order of Account Distributions

Here’s a mistake that costs retirees real money. Withdrawing from the wrong account, in the wrong order, at the wrong time. It sounds small. It isn’t.

The wrong withdrawal order can push you into a higher tax bracket. It can trigger steep Medicare premium surcharges (IRMAA). It can expose more of your Social Security to taxation than necessary. All from decisions that felt harmless in the moment. If you live in Kansas and work in Missouri (or the reverse), this gets an extra layer of complexity — see The Cross-State Retirement Map for how residency and income sourcing affect which state taxes each withdrawal.

Quick answer: The optimal retirement withdrawal order isn’t a fixed sequence you follow forever — it’s an annual, bracket-based decision. Instead of draining taxable accounts first, then tax-deferred accounts, then Roth last (the common default), a fiduciary approach withdraws proportionally from taxable, tax-deferred, and Roth accounts each year to deliberately fill your lower tax brackets. Done well, this reduces lifetime taxes, IRMAA surcharges, and the size of future Required Minimum Distributions (RMDs), which currently begin at age 73.

Why Withdrawal Order Is the Decision Nobody Talks About

Most retirement content focuses on saving. Max out your 401(k). Contribute to a Roth. Build the number. That advice is useful, but it stops right where the real complexity begins.

Once you retire, the question flips. Now you’re deciding which account to pull from, this year, and the next, and the year after that. Every account is taxed differently. Get the order wrong, and you can pay meaningfully more tax than necessary, year after year, for the rest of your retirement.

This isn’t a one-time decision either. It compounds. A poorly sequenced withdrawal in your first retirement year can echo for decades, through higher RMDs later, through Medicare surcharges, through Social Security taxation. Small mistakes early become expensive mistakes late.

The Traditional Sequence vs. The Fiduciary Reality

Most brokers, and most generic retirement calculators, default to the same basic order. Here’s how that standard approach compares to what real, comprehensive planning actually requires.

Approach	What It Does	The Problem
Standard Method	Empty taxable accounts first, then tax-deferred accounts like Traditional IRAs and 401(k)s, then Roth accounts last.	Simple to explain, but ignores your actual tax bracket each year, often leading to bigger tax bills later.
The Fiduciary Reality	Fill your lower tax brackets deliberately every year, using proportional withdrawals across taxable, tax-deferred, and Roth accounts together.	Requires real, ongoing analysis, but can meaningfully extend how long your entire portfolio lasts.

The standard method isn’t wrong, exactly. It’s just incomplete. It treats each account type as a separate bucket, drained one at a time. Real tax optimization treats all your accounts as one system, coordinated together, every single year.

This is also where dividend growth investing plays a role. A portfolio built around rising dividend income can supply some of your annual cash flow without forcing a sale from any single account. That gives you more flexibility to fill tax brackets deliberately, instead of being forced into a withdrawal by cash flow needs alone.

The Optimal Withdrawal Order Framework, Step by Step

There’s no universal withdrawal order that works for everyone, but the underlying process is consistent. Here’s the framework we walk through with clients every year:

Calculate your current-year tax bracket first — before taking any discretionary withdrawals — using guaranteed income like Social Security and pensions as the baseline.
Identify how much “room” remains in your current bracket before you’d cross into the next one.
Withdraw from taxable accounts first to fill that room, since qualified dividends and long-term capital gains are often taxed at 0% or 15% for many retirees.
Use tax-deferred accounts (Traditional IRA, 401(k)) to fill any remaining room in your target bracket deliberately — not by default.
Consider a Roth conversion for any additional room you’re comfortable filling, especially during the years between retirement and age 73.
Preserve Roth IRA withdrawals for last, or for large, unplanned expenses, since qualified Roth withdrawals are tax-free and don’t affect your bracket.
Repeat this analysis every year — your bracket, tax law, and account balances all change, so last year’s plan isn’t automatically this year’s plan.

Strategic Tax Traps to Evade

Two specific traps catch retirees more than any others. Both are avoidable, but only with planning that starts years in advance.

The RMD Tax Cliff

A lifetime of diligent saving in tax-deferred accounts feels responsible. It is. But it sets up a future problem. Required Minimum Distributions currently begin at age 73. They force withdrawals whether you need the income or not. For disciplined savers, RMDs can be large enough to push you into a meaningfully higher tax bracket than you ever experienced while working. Combined with Social Security, this can create the single largest tax burden of your entire retirement, arriving all at once in your seventies.

Proactive Roth Conversions

Here’s the good news. There’s a specific window built for solving this exact problem. It falls between when you stop working and when RMDs begin. During these years, your taxable income is often lower than at any other point in retirement. That makes it an ideal window to convert traditional IRA funds into a Roth IRA, paying tax now at a lower rate, instead of later at a potentially higher one. Done well, this single strategy can meaningfully shrink your future RMDs, and the tax bracket jump that comes with them.

Neither of these traps announces itself in advance. They show up as a surprise tax bill, years after the decisions that caused them. That’s exactly why this kind of planning benefits from a fee-only fiduciary, someone with a direct, ongoing incentive to map this out years ahead, not react to it after the fact.

Frequently Asked Questions

What is the standard retirement withdrawal sequence?

The standard method most brokers use is to withdraw from taxable brokerage accounts first, then tax-deferred accounts like Traditional IRAs and 401(k)s, and Roth accounts last. It’s simple, but it ignores your actual tax bracket each year, which can lead to larger tax bills later in retirement.

How do Required Minimum Distributions affect my retirement taxes?

RMDs currently begin at age 73 and force withdrawals from tax-deferred accounts whether you need the income or not. For diligent savers, this can push you into a meaningfully higher tax bracket, especially when combined with Social Security income, creating a larger tax burden than expected.

When is the best time to do a Roth conversion?

The ideal window is typically between when you stop working and when RMDs begin, since your taxable income is often lower during these years. Converting traditional IRA funds to a Roth IRA during this window means paying tax now at a lower rate instead of a potentially higher rate later.

What order should I withdraw from my retirement accounts?

Rather than a fixed order, withdraw proportionally across taxable, tax-deferred, and Roth accounts each year to deliberately fill your current tax bracket — drawing from taxable accounts first to use low capital-gains rates, then tax-deferred accounts, then considering a Roth conversion, and preserving Roth withdrawals for last.

Key Takeaways

Withdrawal order matters as much as how much you’ve saved, since the wrong sequence can trigger a higher tax bracket, IRMAA surcharges, and added Social Security taxation.
The standard broker default, taxable accounts first, then tax-deferred, then Roth, is simple but often incomplete for true tax optimization.
Real tax optimization fills your lower tax brackets deliberately every year, using proportional withdrawals across account types together.
The RMD tax cliff and the Roth conversion window are the two biggest levers in this entire strategy, and both require planning years in advance.
