What Is a Traditional IRA?

A Traditional IRA is a retirement account where you contribute pre-tax dollars, pay no taxes on growth, and pay taxes on withdrawals in retirement.

How Traditional IRA Works

Step 1: Contribute pre-tax dollars

• You earn $50,000
• Contribute $7,000 to Traditional IRA (deductible)
• Taxable income: $43,000
• Taxes: $4,300 (instead of $5,500 without deduction)
• Tax savings: $1,200 immediately

Step 2: Invest and grow tax-deferred

• $7,000 grows to $70,000 over 30 years
• No taxes owed during growth
• $63,000 in gains, untaxed

Step 3: Withdraw and pay taxes

• At 65+: Withdraw $70,000
• Pay ordinary income taxes on entire withdrawal
• If you're in 22% bracket: Pay $15,400 in taxes
• Net: $54,600

Tax-Deferred vs. Tax-Free

Traditional IRA is tax-deferred (not tax-free):

Tax-deferred: Taxes are delayed until withdrawal

• Pay less in taxes today
• Pay more in taxes later
• Net result: Same total taxes (if rates unchanged)

Tax-free: No taxes ever

• Roth IRA is tax-free
• Much better than Traditional

2024 Contribution Limits

Contribution limit: $7,000/year ($8,000 age 50+)

Deduction phase-out (if you have a 401(k)):

• Single: $77,000-$87,000
• Married filing jointly: $123,000-$143,000

If you exceed these limits and have a 401(k), your contribution is not deductible. This is why backdoor Roth is valuable.

Traditional vs. Roth IRA

Feature	Traditional	Roth
Contribution	Pre-tax (deductible)	After-tax (not deductible)
Growth	Tax-deferred	Tax-free
Withdrawals	Taxed as income	Tax-free
Required distributions	Yes, age 73+	No
Best for	Expecting lower future tax rate	Expecting higher future tax rate

When Traditional IRA is Better

You expect lower tax rates in retirement:

• Earning $100,000 today (24% bracket)
• Will have $30,000 income in retirement (12% bracket)
• Deduction saves 24% now; pay 12% later
• Net savings: 12%

You need the immediate tax deduction:

• High-income year where extra deduction is valuable
• Reduce current taxes more than you'll owe later

When Roth is Better

You expect higher tax rates in retirement:

• Earning $50,000 today (12% bracket)
• Will have $80,000 income in retirement (22% bracket)
• Roth costs nothing now; withdrawals are tax-free
• Traditional would require paying 22% taxes in retirement

You want maximum growth:

• Young person with 40+ year horizon
• Roth's tax-free growth compounds to much higher value

Required Minimum Distributions (RMDs)

Traditional IRAs require withdrawals starting age 73:

Example: $500,000 Traditional IRA at age 73

• RMD: $500,000 ÷ 26.5 (life expectancy factor) = $18,868
• Must withdraw at least $18,868 or pay 25% penalty

Problem: You might not need the money; you're forced to withdraw and pay taxes.

Solution: Roth IRA has no RMDs (you can leave it to heirs).

Roth Conversion Strategy

Convert Traditional IRA to Roth when in low-tax years:

Example:

• You have $200,000 Traditional IRA
• You retire early, have $30,000 income
• You're in 12% tax bracket

Conversion:

• Convert $50,000 to Roth
• Pay 12% tax = $6,000
• $50,000 now grows tax-free forever
• You avoided paying 22-37% taxes later

Roth conversions are powerful in low-income retirement years.

Penalty and Exceptions

Early withdrawal penalty (before 59.5):

• 10% penalty + income taxes
• Exceptions: First-time home buyer ($10,000 lifetime), education, disability, medical expenses

RMD penalty (not withdrawing enough at 73+):

• 25% penalty on amount not withdrawn
• Reduced to 10% if corrected quickly

These penalties make Traditional IRAs less flexible than Roth for early access.

Deductibility Rules

If you or spouse has a 401(k):

• Income below phase-out: Full deduction
• Income in phase-out range: Partial deduction
• Income above phase-out: No deduction

Example: Single, 401(k) available, $85,000 income

• Phase-out range: $77,000-$87,000
• You're halfway through phase-out
• Can deduct ~$3,500 of $7,000 contribution
• Remaining $3,500 is non-deductible

This is frustrating and why backdoor Roth exists.

Backdoor Roth (High-Earner Workaround)

High-earners can bypass Roth income limits:

1. Contribute $7,000 to non-deductible Traditional IRA
2. Immediately convert to Roth
3. Pay minimal taxes (only if gains occurred)
4. Result: $7,000 in Roth despite income limits

The pro-rata rule complicates this if you have existing Traditional IRA balances, but the strategy works.

Tax-Deferred Growth Advantage

The power of tax-deferred growth:

Taxable account: $7,000 invested at 8% for 30 years

• Growth: $70,000
• Taxes on gains at 20%: $14,000
• After-tax value: $63,000

Traditional IRA: $7,000 invested at 8% for 30 years

• Growth: $70,000

• Withdraw at age 65 in 22% bracket: $15,400 taxes

• After-tax value: $54,600

• Tax-deferred still wins (assuming 22% bracket is better than capital gains + reinvestment taxes)

The Bottom Line

Traditional IRAs are valuable if you expect lower taxes in retirement. The immediate deduction saves taxes today; you pay taxes later when (hopefully) you're in a lower bracket.

For young people expecting rising incomes, Roth is usually better. For high-income workers nearing retirement with expected lower retirement income, Traditional can be superior.

The key decision: Will your tax rate be higher or lower in retirement?
