Roth vs Traditional IRA Withdrawal Order: A Tax Guide

Many retirees apply the same rule every year and overpay taxes as a result. When to use Roth vs traditional retirement accounts shifts based on your bracket, your RMDs, and your Social Security income. Getting this right is the difference between a tax-optimized retirement income plan and one that leaves retirement savings on the table year after year.

What Is the Difference Between Roth and Traditional IRA Withdrawals?

Traditional IRA withdrawals are taxed as ordinary income and raise adjusted gross income. Roth IRA withdrawals are tax-free for qualified distributions. That difference determines your retirement income tax mix, which IRA to use first each year, and how the Roth vs traditional IRA withdrawal order plays out over time.

This is the pre-tax vs after-tax retirement accounts distinction in action. Your traditional IRA holds dollars that were never taxed. Your Roth IRA holds dollars taxed at contribution. The traditional IRA withdrawal rules and Roth IRA withdrawal rules each carry their own tax consequences, and managing the mix between them based on your financial needs each year is the foundation of tax-efficient IRA withdrawals and a sound Roth vs traditional IRA withdrawal order across a full retirement.

Which IRA Should You Withdraw From First?

Draw from your traditional IRA first in low-income years when distributions fall in the 10% or 12% bracket. Draw from your Roth IRA first in high-income years when traditional withdrawals would push you into a higher bracket or trigger Medicare IRMAA surcharges. The answer changes year by year.

The conventional Roth vs traditional withdrawal strategy is to tap Roth or traditional first based on whether your bracket is elevated or depressed in a given year. When to use Roth vs traditional retirement accounts is an annual tax projection exercise, not a fixed rule. Treating a Roth IRA vs traditional IRA in retirement means treating both accounts as adjustable levers each year, not a locked sequence.

Required minimum distributions will eventually force distributions from your traditional IRA at whatever bracket applies then, so drawing it down in low-bracket years reduces future RMDs and smooths your lifetime tax burden. Traditional IRA tax deferral has real value, but every dollar left in a traditional IRA is a future distribution amount taxed at ordinary income tax rates, and the financial planner or financial advisor who ignores that trajectory is leaving a retirement savings problem unaddressed.

Draw from your Roth IRA first when income spikes. Additional traditional IRA withdrawals in a high-income year can cause more of your Social Security benefits to become taxable and trigger IRMAA Medicare surcharges. Roth IRA withdrawal tax-free treatment fills an income gap without raising adjusted gross income, making it the right tool in high-income years.

At What Age Should You Start Taking Withdrawals From Your Traditional and Roth IRAs?

You can withdraw from a traditional IRA penalty-free starting at age 59.5, and you must begin required minimum distributions at age 73. Roth IRAs allow penalty-free qualified withdrawals at 59.5 with no mandatory distribution requirement at any age, making the timing entirely your choice.

The age rules differ meaningfully between account types and should drive how you think about early retirement income. Before age 59.5, withdrawals from either a traditional or Roth IRA can trigger a 10% early withdrawal penalty, though the Roth IRA has more flexibility: you can always withdraw your original contributions (not earnings) from a Roth at any age without penalty or tax, since those dollars were already taxed. Traditional IRA early withdrawals before 59.5 are fully taxable as ordinary income plus the penalty, making them expensive to access before the threshold.

Between age 59.5 and 73, both accounts are accessible penalty-free, but the Roth IRA has a distinct advantage: no requirement to take anything out at all. That window of up to 13 years before RMDs begin is the optimal period to manage the Roth vs traditional IRA withdrawal order deliberately, drawing down the traditional IRA in low-income years and leaving the Roth untouched to continue compounding. Once RMDs begin at 73, the IRS sets a floor on traditional IRA distributions regardless of whether you need the income, and that floor rises each year as the account balance grows relative to the declining life expectancy divisor.

The Core Tax Difference: Traditional IRA Taxable Withdrawals vs Roth IRA Tax-Free Income

How traditional IRA taxable withdrawals work. Every dollar you withdraw from a traditional IRA is added to your ordinary income for that tax year. The tax treatment is identical to wages: it is taxed at your marginal rate using ordinary income tax rates, affects your adjusted gross income, and can push other income into a higher tax bracket. Traditional IRA taxable withdrawals interact with Social Security taxation thresholds, Medicare IRMAA surcharges, and the net investment income tax at higher income levels. None of those interactions apply to Roth IRA withdrawals.

Traditional IRA RMD impact compounds over a retiree’s life expectancy. A retiree who defers distributions through their 60s may arrive at age 73 with a balance large enough to generate RMDs of $60,000, $80,000, or more per year whether or not that dollar amount is needed for regular income. Those forced distributions push Social Security income into higher taxable brackets, trigger IRMAA surcharges on Medicare premiums, and can move capital gains taxes from the 0% rate into the 15% rate. The RMD is not just a distribution; it is a taxable income event that affects every other calculation that year.

How Roth IRA withdrawal tax-free treatment works. Roth IRA withdrawal tax-free treatment applies to qualified distributions: those taken after age 59.5 from an account that has been open for at least five years. The Roth IRA no RMD rule means the account can compound indefinitely during your lifetime without any forced distributions. You control the timing entirely. Roth IRA advantages in retirement extend beyond the individual account: because Roth withdrawals do not count as income, they do not affect Social Security taxation, Medicare premiums, or any other income-tested benefit or threshold. A retiree drawing $40,000 per year from a Roth IRA looks like they have no income at all from the IRS perspective.

When to Use Roth vs Traditional in Retirement: Key Scenarios

In your first years of retirement before Social Security begins, you often hit the lowest-income window of your retirement. If you retire at 62 and delay Social Security until 70, you may have eight years with little or no ordinary income. That window is the optimal time to draw from your traditional IRA at low marginal rates, potentially in the 10% or 12% bracket. It is also the prime window for Roth conversion in retirement: converting traditional IRA dollars to Roth while income is low locks in a low tax rate on money that would otherwise generate larger taxable RMDs later. The Roth conversion strategy and your IRA withdrawal sequence should be coordinated during this period as part of the same plan.

Once RMDs begin at age 73, the traditional IRA RMD impact changes the sequencing question. You no longer have full control over how much you take from your traditional IRA: the IRS sets a floor. For retirees with large traditional IRA balances, those mandatory distributions may generate more income than needed for living expenses, pushing into higher brackets and triggering IRMAA surcharges. In that situation, the Roth IRA becomes the account to draw from for any income needed above the RMD floor, since Roth withdrawals do not add to the income that determines IRMAA thresholds. Tax diversification retirement planning means building enough assets in both account types so you have this flexibility.

Managing Social Security taxation through IRA distribution strategy

Up to 85% of Social Security benefits can become taxable depending on your combined income. The combined income calculation includes adjusted gross income plus nontaxable interest plus half of Social Security. Traditional IRA withdrawals add directly to adjusted gross income, which flows straight into this formula. Roth IRA withdrawals do not. A retiree who draws $20,000 from a traditional IRA and $20,000 from a Roth IRA faces a very different Social Security taxation outcome than a retiree who draws $40,000 entirely from a traditional IRA. Coordinating the Roth vs traditional IRA withdrawal order with your Social Security optimization strategy is one of the highest-value tax planning moves available to many retirees.

Tax bracket management Roth strategy for high-income years

In years with unexpected income spikes, such as a large capital gain from selling a rental property, a business distribution, or a substantial inheritance, Roth IRA withdrawals allow you to cover living expenses without adding fuel to an already-elevated income year. Traditional IRA withdrawals in a high-income year can push marginal dollars into the 32% or 37% bracket. Roth dollars in that same year cost nothing in additional tax. Retirement income tax mix across account types is what gives you the flexibility to navigate income volatility without paying avoidable taxes.

The Role of Tax Diversification in Retirement

Tax diversification retirement planning means deliberately holding assets in multiple retirement account tax types: pre-tax traditional IRA balances, tax-free Roth IRA balances, and after-tax taxable brokerage accounts. No one account type is optimal in every year. Having all three gives you the withdrawal rules and flexibility to select which dollars to spend in a way that minimizes tax across your full retirement, rather than being locked into a single source when financial needs shift unexpectedly.

A retiree with $800,000 in a traditional IRA and nothing in a Roth has no flexibility. Every dollar of retirement income beyond Social Security comes out at ordinary income rates and feeds the RMD problem. A retiree with $500,000 in a traditional IRA, $200,000 in a Roth IRA, and $100,000 in a taxable account has three levers to pull each year, each with different tax treatment, and can assemble an income stream that minimizes the tax rate on every marginal dollar.

Building that mix is the purpose of the Roth ladder retirement strategy: systematically converting traditional IRA dollars to Roth over years or decades, paying tax at a controlled rate today to eliminate a larger forced tax event in the future. The tax-efficient investing framework and the Roth vs traditional IRA withdrawal order work in the same direction: reduce the traditional IRA balance at favorable rates, build the Roth balance, preserve flexibility.

Roth IRA Advantages in Retirement Beyond the Tax-Free Withdrawal

The Roth IRA no RMD rule is the most underappreciated tax break available to retirees. Because the IRS does not require distributions, the Roth account can compound for decades without interference. A 65-year-old with $200,000 in a Roth IRA who never touches it until age 85 has 20 years of tax-free growth. A traditional IRA of the same size will have been generating taxable RMDs since age 73, shrinking the compounding base and adding to taxable income throughout.

Roth accounts also have a significant estate planning advantage. Non-spouse beneficiaries who inherit a Roth IRA are subject to the 10-year distribution rule under the SECURE Act, as with traditional IRAs, but Roth distributions to heirs are still tax-free. A beneficiary inheriting a $400,000 traditional IRA faces the same 10-year rule but with ordinary income tax on every distribution. That distinction can represent $80,000 to $120,000 or more in taxes depending on the beneficiary’s bracket. The first year of retirement is also the first year to start thinking about this: preserving your Roth for inheritance and drawing down your traditional IRA during your lifetime is often the most tax-efficient estate strategy when both account types are available.

How This Fits Into a Broader Withdrawal Strategy

The Roth vs traditional IRA withdrawal order is one layer of a complete tax-efficient IRA withdrawal plan. The full sequence also involves taxable brokerage accounts and the timing of Social Security, pension income, and any part-time work. The retirement withdrawal strategy guide maps how all of those sources interact and where the IRA-specific decision sits within that larger picture: you cannot optimize Roth vs traditional in isolation without knowing your total income for the year.

Getting this right is not a one-time decision. It is an annual recalculation. Each year’s income projection, tax bracket position, RMD amount, and Social Security status determines which IRA to draw from and how much. A fiduciary retirement planning approach builds this into the ongoing planning process rather than treating it as a set-and-forget choice made at retirement. The Preserve. Strengthen. Grow.™ philosophy applies here directly: the Roth balance is preserved during accumulation so it is available as a precision tax management tool during distribution. That is not an accident. It is the plan.
