The IRS gave you these accounts. Use them.
The IRS gave you these accounts. Use them.
Every tax-advantaged account gives you a tax break — the question is when. Pre-tax accounts (Traditional 401(k), IRA) give you the deduction now and tax you on withdrawal. After-tax accounts (Roth) give you no deduction now, but withdrawals in retirement are tax-free.
The math generally favors pre-tax if you're in a higher bracket now than you expect in retirement, and Roth if you're in a lower bracket now or expect tax rates to rise. When you're unsure, splitting between both hedges the bet.
Tax treatment at contribution, during growth, and at withdrawal.
Account | Tax Now | Tax Later | 2025 Limit | Best For |
|---|---|---|---|---|
Traditional 401(k) | Pre-tax contributions | Withdrawals taxed as ordinary income | $23,500 ($31,000 age 50+) | High earners expecting a lower tax rate in retirement |
Roth 401(k) | After-tax contributions | Withdrawals tax-free in retirement | $23,500 ($31,000 age 50+) | Younger earners or those expecting higher tax rates in retirement |
Traditional IRA | Pre-tax (if income-eligible) | Withdrawals taxed as ordinary income | $7,000 ($8,000 age 50+) | No workplace 401(k), or high earners using backdoor Roth |
Roth IRA | After-tax contributions | Withdrawals tax-free (including earnings) | $7,000 ($8,000 age 50+); phases out above $150K/$236K AGI | Those who expect higher rates later, or want flexible withdrawals |
HSA | Pre-tax contributions | Tax-free for medical; ordinary income tax if non-medical after 65 | $4,300 self-only / $8,550 family | Anyone on a High Deductible Health Plan — the only triple-tax account |
529 Education Plan | After-tax (federal); some states give a deduction | Withdrawals tax-free for qualified education expenses | No annual limit (gift tax applies above $19,000/year) | Parents saving for college |
If you have limited dollars, prioritize in this order to maximize every tax advantage:
1. 401(k) up to employer match — free money first. Always capture the full employer match before doing anything else.
2. Max your HSA — triple tax advantage makes this the most powerful account per dollar, if you have an HDHP.
3. Max your Roth IRA (if eligible) — tax-free growth and no RMDs make it highly valuable. Income limit: $150K single / $236K MFJ.
4. Max your 401(k) — go back and max the full $23,500 contribution limit after IRA and HSA are fully funded.
5. Taxable brokerage account — once all tax-advantaged space is used, invest in a regular brokerage using tax-efficient ETFs.
Roth vs Traditional — the quick rule: in your 20s–30s at lower income, Roth usually wins since you're in a low bracket now. In peak earning years (40s–50s, higher bracket), Traditional is often better for the bigger deduction now. Unsure? Split it — many employers allow splitting 401(k) contributions between traditional and Roth. High income but want Roth? Use the backdoor Roth IRA strategy.
Picking Roth or Traditional based on a guess, not a bracket comparison: The right choice depends on comparing your current tax bracket to your expected bracket in retirement — not a blanket preference for one type.
Skipping the employer match to fund an IRA first: Employer matching dollars are an immediate 100% return — always capture the full match before directing money elsewhere.
Ignoring RMDs when choosing between accounts: Traditional 401(k)s and IRAs force withdrawals starting at age 73, which can push you into a higher bracket later — Roth IRAs avoid this entirely.
Tax-Deferred: you don't pay tax on the money now — it grows inside the account without annual taxes, but you pay ordinary income tax when you withdraw in retirement. Traditional 401(k) and IRA are tax-deferred.
Tax-Free Growth: earnings inside the account are never taxed as long as you follow the withdrawal rules. Roth accounts and HSAs (for medical expenses) offer tax-free growth.
Backdoor Roth IRA: a strategy for high earners who exceed the Roth IRA income limit. Contribute to a non-deductible Traditional IRA, then convert it to a Roth. Legal and widely used, but watch the pro-rata rule if you have other IRA balances.
RMDs (Required Minimum Distributions): the IRS requires you to start withdrawing from Traditional 401(k)s and IRAs at age 73. Roth IRAs have no RMDs during the owner's lifetime — a key advantage for estate planning.
Pre-tax (Traditional): deduction now, taxed on withdrawal — best for high earners today
Roth: no deduction now, tax-free withdrawal — best for lower brackets or rising tax expectations
HSA: the only triple-tax-advantaged account — max it if you have an HDHP
Priority order: 401(k) match → HSA → Roth IRA → max 401(k) → taxable brokerage
Roth IRA has no RMDs — powerful for estate planning and flexible retirement income
High income and want Roth? Use the backdoor Roth IRA strategy
Splitting contributions between both hedges the uncertainty — many employers let you divide 401(k) contributions between Traditional and Roth.
Contribute enough to your 401(k) to get the full employer match first — it's an immediate, guaranteed return before anything else.
It's the only account that's tax-free going in, tax-free growing, and tax-free coming out for medical expenses — a triple advantage no other account offers.
You can use the backdoor Roth IRA strategy — contribute to a non-deductible Traditional IRA, then convert it to a Roth.
No — Roth IRAs have no RMDs during the owner's lifetime, which makes them useful for estate planning and flexible income later in life.
Not quite — contributions aren't federally deductible, but growth and withdrawals for qualified education expenses are tax-free, and some states offer their own deduction.
