Tax-Advantaged Retirement Accounts

Retirement accounts are really just buckets with different tax labels. A useful plan involves more than one. The flexibility that comes from operating in all three buckets — taxable, tax-deferred, tax-free — is the single most under-appreciated financial-planning advantage available to most Americans.

The three tax buckets

• Taxable — brokerage accounts, savings. Pay tax on dividends annually, and on realized gains when sold. No contribution limits.
• Tax-deferred — traditional 401(k) / IRA / SEP / SIMPLE. Deduction now, ordinary income tax at withdrawal. RMDs apply starting at age 73 (rising to 75).
• Tax-free — Roth 401(k) / IRA, properly structured IUL, HSA for medical expenses. Pay tax now; qualified withdrawals are tax-free. Roth 401(k) lost its RMD requirement under SECURE 2.0.

Owners with balances in all three buckets sleep better in retirement because they can adapt to whatever income pattern emerges. A bad market year becomes a year to lean on the taxable bucket; a high medical year is an HSA year; a high-income year means temporarily suspending Roth conversions. Flexibility is the goal — and balance across all three buckets is what creates that flexibility.

Contribution limits (2024 — current figures at year of use)

Account-by-account overview

Traditional IRA

Up to $7,000/week ($8,000/week if 50+). Deductible contribution phases out at higher incomes if also covered by a workplace retirement plan. Tax-deferred growth. Withdrawals taxed as ordinary income. RMDs apply starting at age 73.

Roth IRA

Same contribution limit as traditional IRA, but the income limits that restrict direct contributions can run as low as $146k-modified-AGI (single) to $240k+ depending on filing status. Pay tax now; qualified withdrawals are tax-free. No RMDs during the owner's lifetime. Backdoor Roth IRAs remain available for higher-income earners — but the pro-rata rule makes them tricky when other traditional IRAs already hold balances.

401(k), 403(b), TSP

Employee elective deferrals up to $23,000 in 2024, higher catch-up limits apply. Employer contributions (match, profit-sharing, non-elective) sit on top. Roth 401(k) is now available at no income limit — a major SECURE 2.0 change. Designated Roth accounts in 401(k) match are now permitted when the employer elects and the employee elects.

SEP-IRA

Simplified employer pension. Employer contributes up to 25% of compensation for each eligible employee, including the owner. Best when there are a small number of employees and you don't want the complexity of running a 401(k) plan.

Solo 401(k)

Most owner-only businesses should consider a Solo 401(k) once profitability supports the contribution. Combines the employee elective deferral with employer non-elective contributions. Allows Roth option. Higher deductible contribution than SEP for the same business income.

SIMPLE IRA

For employers with up to 100 employees who earned $5,000+ in the prior year. The employer must contribute either 100% match up to 3% of compensation, or a flat 2%. Lower contribution limits than other plans, but also lower setup cost.

Health Savings Account (HSA)

The single most tax-efficient account available. Triple advantage: deductible going in, tax-free growth, tax-free withdrawals for qualified medical expenses. After 65, non-medical withdrawals are taxed like a traditional IRA (no 20% penalty). Many people miss this — particularly those on HDHPs who contribute zero.

SECURE 2.0 highlights that affect every retirement saver

• RMDs: starting age 73 in 2024, increasing to 75 in 2033. Roth 401(k) RMDs eliminated effective 2024.
• Roth employer match: employers may offer Roth treatment for match contributions; employee election required.
• Emergency savings accounts in workplace plans: new short-term savings vehicle inside 401(k) for unexpected expenses.
• Student loan match: employers may match student-loan payments as if they were retirement contributions.
• Higher catch-up for ages 60–63: a $11,250 extra (vs. $7,500) catch-up from 2025.
• Reduced missed-RMD penalty: 25%, or 10% if corrected within two years of the missed RMD.

Strategic decisions

Roth conversion: when it makes sense

Best when current marginal rate is meaningfully lower than expected retirement rate. Best when you have cash outside the retirement account to pay the conversion tax (otherwise, you shrink the account's future growth in a way that offsets the conversion benefit). Bridge years — between retirement and Social Security, between jobs, or during a sabbatical — are classic Roth-conversion windows.

Multi-bucket drawdown in retirement

Once you have balances in all three buckets, the drawdown strategy is: satisfy required minimum distributions first; then draw from the bucket with the worst future tax outlook; preserve Roth growth as long as possible; use taxable accounts for charitable intent (Qualified Charitable Distributions remain available for those 70½+); use HSA balances for current medical expenses if the balance is large enough to project against future Medicare premiums and long-term care.

Common mistakes worth avoiding

1. Not capturing the employer match — leaving 50–100% instant-return money on the table.
2. Co-mingling beneficiary designations — life events (marriage, divorce, birth, adoption) almost always require updating beneficiaries on every account.
3. Missing the 60-day rollover window after a job change — funds become taxable and often subject to a 10% penalty.
4. Pro-rata traps in backdoor Roth IRA contributions — pre-tax IRA balances can effectively zero-out the conversion benefit.
5. Cashing out small 401(k) balances at job change rather than rolling them into a new plan.
6. Forgetting that HSAs are individually owned — switches in HDHP coverage don't transfer balances.
