Tax-Efficient Withdrawal Strategies After Roth Conversion

You’ve done the hard work of converting pre-tax retirement savings into a Roth IRA. Now comes the next step withdrawing your funds in a way that minimizes taxes and maximizes income.

Roth conversions give you more flexibility in retirement, but the benefits only fully materialize if you use the right withdrawal strategy. In this guide, we’ll break down how to structure your withdrawals post-conversion, manage required minimum distributions (RMDs), and use Roth ladders and tax bracket optimization to your advantage.

Understand the Basics: How Withdrawals Are Taxed After a Roth Conversion

A Roth IRA allows tax-free qualified withdrawals, but only if:

You’re age 59½ or older, and
At least five years have passed since your first Roth contribution or conversion

Traditional IRAs and 401(k)s, on the other hand, are taxable upon withdrawal and come with required minimum distributions (RMDs) starting at age 73 (as of 2025).

So if you have multiple retirement accounts, your goal should be to withdraw:

Enough from traditional accounts to stay within a low tax bracket
Let Roth funds grow tax-free longer
Avoid unnecessary tax hits

Use the “Withdrawal Order” Strategy

A common, tax-smart strategy is to tap accounts in this order:

Taxable accounts (brokerage)
Traditional 401(k)/IRA (to fill lower tax brackets)
Roth IRA (save for last)

This sequencing allows you to:

Use capital gains rates in taxable accounts early on
Reduce future RMDs by drawing down traditional accounts
Let Roth assets compound tax-free for as long as possible

Watch Out for RMDs After Conversion

Roth IRAs don’t have RMDs during your lifetime, but Traditional IRAs do and Roth 401(k)s do too unless rolled into a Roth IRA.

Strategy:

Convert Traditional accounts before RMD age (age 73)
Roll over Roth 401(k)s into Roth IRAs to eliminate RMDs
If you’re over 73, you must take that year’s RMD first before converting any traditional funds

Roth Conversion Ladder: Stretch Conversions Over Time

If you converted only part of your retirement funds, you may be using a Roth conversion ladder a method of converting a set amount each year to manage taxes.

Each converted amount starts its own 5-year clock for penalty-free withdrawals. Plan your withdrawals around this timing to avoid early withdrawal penalties if you’re under 59½.

For example:

2021 conversion becomes penalty-free in 2026
2022 conversion in 2027, and so on

This ladder strategy works best if:

You’re retiring early
You want to avoid draining taxable accounts first
You’re carefully staying within a chosen tax bracket

Tax Bracket Optimization: Smooth Your Lifetime Tax Burden

One of the smartest post-conversion strategies is to use tax bracket management. Here’s how:

If you have taxable income well below the top of your current bracket, fill in the gap with small traditional IRA withdrawals.
Avoid jumping into a higher bracket with large one-time withdrawals.
Use Roth withdrawals in high-income years to keep your taxable income low.

Example:

You’re in the 22% bracket, with $10,000 of space before hitting the 24% bracket. You can withdraw up to $10,000 from your Traditional IRA to fill that gap, while pulling any additional income from your Roth IRA tax-free.

Consider Timing Around Social Security and Medicare

Be strategic about when you:

Claim Social Security (delaying it can give you more room to convert or withdraw taxably)
Start Medicare (income over $103,000 for individuals can trigger higher Part B/D premiums in 2025)

If you’ve already converted, consider pulling taxable withdrawals before age 65 to avoid IRMAA (Income-Related Monthly Adjustment Amount) surcharges later.

Withdrawal Planning Example

Age	Account	Withdrawal Amount	Tax Notes
60	Taxable	$20,000	Mostly capital gains
61	Traditional IRA	$15,000	Ordinary income
62	Roth IRA	$10,000 (optional)	Tax-free if 5-year rule is met
63+	Traditional IRA	$10,000/year	To stay in 12–22% bracket
73+	RMDs only	Variable	Required from traditional IRA unless converted fully

Key Tips to Stay Tax-Efficient

Automate annual reviews with a CPA or financial planner
Use tax software or calculators to test withdrawal scenarios
Keep records of all Roth conversions (Form 8606) to verify basis
Don’t forget state taxes—some states don’t tax Roth IRA withdrawals, others do

Final Takeaway: Plan Early, Withdraw Strategically

A Roth conversion opens doors for smart tax planning but only if you follow through with an intentional withdrawal strategy. Use your Roth as a tax-free safety valve, minimize RMD exposure, and always look for ways to balance your tax bracket annually.

Whether you’re drawing down accounts or just planning ahead, even small adjustments each year can save thousands over time.
