Which Should You Choose?
Choose Roth IRA if you...
- Are early in your career with lower income now
- Expect to earn more in the future and be in a higher tax bracket
- Want the flexibility to withdraw contributions at any time
- Want to avoid Required Minimum Distributions in retirement
- Want to leave tax-free money to your heirs
- Believe tax rates will increase in the future
- Want tax diversification in your retirement portfolio
Choose Traditional IRA if you...
- Are in a high tax bracket now (32%+) and expect a lower one in retirement
- Need the tax deduction this year to reduce your current tax bill
- Are close to retirement with fewer years for Roth gains to compound
- Have no access to a Roth 401(k) through your employer
- Expect your income to decrease significantly in retirement
- Live in a high-tax state now but plan to retire in a low-tax state
- Want to lower your adjusted gross income for other tax benefits
When it is genuinely unclear
- -Split your contributions between both accounts to hedge your tax bets
- -Contribute to a Roth while your income is lower, then switch to Traditional as earnings grow
- -Use a Roth for your IRA and Traditional for your 401(k) to get diversification

Withdrawal Rules
Traditional IRA Withdrawals
Before age 59.5
10% early withdrawal penalty plus income tax on the full amount. Exceptions include first home purchase ($10K), higher education expenses, and disability.
After age 59.5
No penalty. Withdrawals taxed as ordinary income at your current bracket.
Required Minimum Distributions at 73
You must begin withdrawing each year. The amount increases based on IRS life expectancy tables.
Example: $500K balance at age 73 means a first-year RMD of approximately $18,900 added to your taxable income.
Roth IRA Withdrawals
Contributions (at any time)
Withdraw your contributions tax-free and penalty-free at any age, for any reason. This is money you already paid tax on.
Earnings (after 59.5 + 5-year rule)
Earnings are tax-free and penalty-free once you hit both milestones. Before that, earnings face a 10% penalty.
No RMDs. Ever.
You can leave the entire balance to grow for your lifetime and pass it to heirs tax-free.
Example: you contributed $50K total. Your Roth is now worth $200K. You can withdraw up to $50K at any time. The $150K in earnings waits until 59.5.
The Backdoor Roth IRA
For high earners who exceed the Roth IRA income limits.
Contribute to a non-deductible Traditional IRA
Put up to $7,000 ($8,000 if 50+) into a Traditional IRA. Do not claim a tax deduction.
Convert to a Roth IRA
Ideally within a few days, before the contribution earns anything significant. Contact your brokerage to initiate the conversion.
Pay tax on any gains
If there were any earnings between contribution and conversion, you owe income tax on that small amount. With a quick conversion, this is typically negligible.
Watch out for the pro-rata rule
If you have existing pre-tax Traditional IRA balances, you cannot convert just the after-tax portion. The IRS treats all your Traditional IRA money as one pool and prorates the tax.
Solution for existing balances
Roll your existing pre-tax Traditional IRA funds into a 401(k) first. Then do the Backdoor Roth with a clean slate to avoid the pro-rata issue.
Roth Conversion Strategy
When and how to convert a Traditional IRA to a Roth IRA.
Convert in low-income years
Sabbaticals, early retirement before Social Security, or market downturns are ideal times. You pay less tax on the conversion.
Stay within your bracket
Convert up to the top of your current tax bracket but not beyond. Pushing into a higher bracket erodes the benefit.
Spread across multiple years
Large balances should be converted gradually over several years to avoid a single massive tax hit.
Pay tax from outside the IRA
Use a non-retirement account to pay the conversion tax. Withholding from the conversion itself reduces the amount that grows tax-free.
The 5-year rule applies
Each conversion has its own 5-year clock. Converted amounts withdrawn before 5 years may face a 10% penalty if you are under 59.5.
Consider state taxes
Some states do not tax retirement income. Converting while in a high-tax state and retiring in a no-tax state could mean paying unnecessary state tax on the conversion.
Common Mistakes to Avoid
Contributing to a Roth when your income is too high
Check the MAGI limits before contributing. If you are over the limit, use the Backdoor Roth method instead. An excess contribution incurs a 6% penalty per year.
Forgetting about Required Minimum Distributions
Traditional IRA RMDs start at age 73 and are mandatory. Missing an RMD triggers a 25% penalty on the amount you should have withdrawn. Set calendar reminders or automate distributions.
Not considering state taxes
Some states fully tax IRA withdrawals, others exempt retirement income entirely. Your state tax situation can significantly change which IRA type wins. Factor in where you plan to retire.
Converting too much to Roth in a single year
A large Roth conversion can push you into a much higher federal bracket and trigger additional Medicare surcharges (IRMAA). Spread conversions across years to stay within lower brackets.
Withdrawing Roth earnings before the 5-year rule
Even after 59.5, Roth earnings are not tax-free unless the account has been open for at least 5 years. Open your first Roth as early as possible to start the clock.
Ignoring the pro-rata rule on backdoor conversions
If you have pre-tax money in any Traditional IRA (including SEP and SIMPLE IRAs), the tax on a Backdoor Roth conversion is calculated across all balances. Roll pre-tax funds into a 401(k) first.
Why Not Both?
You do not have to pick just one. Having both Traditional and Roth accounts gives you tax diversification in retirement.
