Roth IRA vs. Traditional IRA: Tax Treatment and Withdrawal Rules

Two Paths to the Same Destination

In 1974, ERISA created the Individual Retirement Account (IRA) as a tax-deferred savings vehicle for Americans without employer-sponsored retirement plans. In 1997, the Taxpayer Relief Act added a new variant — named for Senator William Roth of Delaware — that flipped the tax timing entirely. Today, Americans hold over $13.1 trillion in IRAs collectively, making them the single largest component of U.S. retirement assets. The choice between the two flavors turns on a single core question: do you expect to pay a higher tax rate now or in retirement?

2024 Contribution Limits

Account Type	Under Age 50	Age 50 and Over (Catch-Up)
Traditional IRA	$7,000	$8,000
Roth IRA	$7,000	$8,000
Combined (both accounts)	$7,000 total	$8,000 total

The $7,000 limit applies across all IRAs combined — a person cannot contribute $7,000 to a Roth and another $7,000 to a Traditional IRA in the same year. Contributions must be made from earned income (wages, salaries, self-employment income); investment income does not qualify.

Income Limits

Traditional IRA Deductibility

Anyone with earned income can contribute to a Traditional IRA, but the tax deductibility depends on income and access to a workplace retirement plan:

If neither spouse is covered by an employer plan, contributions are fully deductible regardless of income.
If the contributor (or their spouse) is covered by an employer plan, deductibility phases out based on Modified Adjusted Gross Income (MAGI). In 2024, the deduction phases out between $77,000–$87,000 (single) and $123,000–$143,000 (married filing jointly, covered spouse).
Non-deductible Traditional IRA contributions are still allowed for anyone with earned income — the contribution goes in after-tax, and growth defers until withdrawal.

Roth IRA Income Limits

Unlike the Traditional IRA, Roth IRA contributions are subject to income phase-outs regardless of employer plan access:

Filing Status	2024 Phase-Out Begins	2024 Phase-Out Ends (no contribution)
Single / Head of Household	$146,000	$161,000
Married Filing Jointly	$230,000	$240,000
Married Filing Separately	$0	$10,000

Tax Treatment Comparison

Feature	Traditional IRA	Roth IRA
Contributions	Pre-tax (if deductible)	After-tax
Growth	Tax-deferred	Tax-free
Qualified withdrawals	Taxed as ordinary income	Tax-free
Early withdrawal (before 59½)	Tax + 10% penalty on full amount	Contributions withdrawn tax/penalty-free; earnings: tax + 10% penalty
Required Minimum Distributions	Begins at age 73	None during owner's lifetime
Beneficiary treatment	Inherited IRAs require distributions within 10 years (for most non-spouse heirs)	Same 10-year rule, but distributions are tax-free

The Backdoor Roth IRA

High earners above the Roth IRA income limits can still access Roth benefits through the backdoor Roth conversion. The process:

Make a non-deductible contribution to a Traditional IRA (no income limit).
Convert the Traditional IRA to a Roth IRA.
If no other pre-tax IRA balances exist, the conversion is tax-free (only the basis is converted).
If pre-tax IRA balances exist elsewhere, the pro-rata rule applies, making partial conversions taxable.

The IRS has not prohibited this strategy, and Congress has repeatedly declined to eliminate it despite proposals from several administrations.

Roth Conversion Strategy

Traditional IRA holders can convert all or part of their balance to a Roth IRA at any time. The converted amount is added to taxable income in the year of conversion — a tax cost paid today to eliminate future taxes. Conversions are most advantageous in low-income years (early retirement before Social Security begins, years with large deductions, or years when investment losses reduce income). The SECURE 2.0 Act of 2022 eliminated RMDs for Roth 401(k)s beginning in 2024, aligning them with Roth IRA treatment.

Roth IRA Withdrawal Rules in Detail

Roth IRA contributions — but not earnings — can be withdrawn at any time without tax or penalty, since contributions were already taxed. Qualified distributions of earnings (tax-free) require both:

The account be at least five years old from the first contribution to any Roth IRA; and
The owner be at least 59½ (or disabled, deceased, or a first-time homebuyer using up to $10,000).

The five-year clock starts January 1 of the year of the first Roth IRA contribution, regardless of the specific date. Opening a Roth at 58 means waiting until 63 for truly tax-free earnings distributions.

Which Account to Choose

The traditional decision framework is straightforward: contribute to whichever account offers the higher tax advantage. Young workers in low tax brackets who expect higher income in retirement favor the Roth. High earners in peak earning years who expect lower retirement income favor the Traditional. Many financial planners advocate contributing to both over a career to build tax diversification — a mix of pre-tax and after-tax retirement income that provides flexibility to manage taxable income in retirement.
