IRA (Individual Retirement Account)
A US tax-advantaged retirement account that an individual opens independently of an employer. The two main types are Traditional (tax-deferred) and Roth (tax-free withdrawals in retirement).
Traditional vs. Roth
Two main IRA types:
- Traditional IRA — contributions may be tax-deductible (subject to income limits if covered by workplace retirement plan); growth is tax-deferred; withdrawals in retirement taxed as ordinary income.
- Roth IRA — contributions are made with after-tax dollars; growth is tax-free; qualified withdrawals in retirement are entirely tax-free.
The choice between them is essentially a bet on whether your tax rate will be higher in retirement (favor Roth) or lower (favor traditional). Most workers benefit from having some of each across their retirement-saving life.
2025 contribution limits
- Standard limit: $7,000.
- Catch-up (age 50+): additional $1,000.
- Combined across all IRAs, not per-account.
Roth IRA contributions phase out at higher income levels (singles around $146-$161K MAGI for 2025; married joint around $230-$240K). Traditional IRA contributions are unlimited regardless of income, but deductibility phases out for those covered by workplace plans.
Why IRAs matter
Even with workplace retirement plans, IRAs add value:
- Roth IRA — tax-free growth and withdrawals; not commonly available through workplace 401(k)s except via Roth 401(k) option.
- Investment flexibility. IRAs typically have unlimited investment options vs. workplace plans' limited menus.
- No fees in self-directed IRAs at major brokerages (Vanguard, Schwab, Fidelity).
- Backdoor Roth — high earners use Traditional-then-Roth conversion to access Roth treatment despite income limits.
Distributions
For Traditional IRAs:
- Required Minimum Distributions (RMDs) begin at age 73 (rising to 75 for younger cohorts).
- Early withdrawal penalty (10%) below age 59½, with exceptions for first-home purchase, education, medical expenses.
- Tax owed on traditional withdrawals; not on Roth.
For Roth IRAs:
- No RMDs during the original owner's lifetime.
- Contributions can be withdrawn anytime tax- and penalty-free.
- Earnings subject to 5-year rule and age 59½ for fully tax-free withdrawal.
Where to open
Major brokerages offer IRAs with no fees:
- Vanguard, Schwab, Fidelity — all offer no-fee IRAs with broad investment options.
- Robo-advisors (Betterment, Wealthfront) — managed portfolios with target allocations.
- Self-directed IRAs at specialized custodians — for non-traditional assets (real estate, crypto, private equity). More expensive and complex.
Common strategies
A few patterns:
- Max IRA every year. $7K isn't a fortune but compounds significantly.
- Roth ladder for early retirees — convert Traditional to Roth gradually in low-income years; access converted amounts after 5 years tax-free.
- Backdoor Roth for high earners.
- Mega backdoor Roth through 401(k) plans that allow after-tax contributions and in-plan Roth conversions.
For most workers, contributing to a workplace 401(k) up to match plus maxing a Roth IRA captures the highest-leverage tax-advantaged saving available.
