Key Benefits

• Tax advantages: Reduce taxable income or enjoy tax‑free withdrawals.
• Compound growth: Decades of reinvested earnings multiply wealth.
• Employer matching: Free money that accelerates savings.
• Automatic discipline: Regular contributions enforce consistency.

3. Traditional vs. Roth: Choosing the Right Tax Strategy

Traditional Accounts

• Contributions reduce taxable income now.
• Withdrawals taxed later.
• Best if you expect lower tax rates in retirement.

Roth Accounts

• Contributions made after taxes.
• Withdrawals are tax‑free.
• Best if you expect higher future tax rates or want flexibility.

Comparison Table

Feature	Traditional	Roth
Tax on Contributions	Deductible	Not deductible
Tax on Withdrawals	Taxed	Tax‑free
Required Minimum Distributions (RMDs)	Yes (starting at age 73)	None for Roth IRAs
Ideal For	High earners now	Younger investors or those expecting higher taxes later

4. Employer‑Sponsored Plans: Maximizing the Match

401(k)

• Most common retirement plan — used by 43% of U.S. workers.
• Employers often match 3–6% of salary.
• Contributions are automatic via payroll deduction.
• Investment options include mutual funds, ETFs, and target‑date funds.

403(b) and 457(b)

• Similar to 401(k) but for nonprofit and government employees.
• 457(b) allows penalty‑free withdrawals upon job separation.

Thrift Savings Plan (TSP)

• Federal equivalent of a 401(k).
• Offers low‑cost index funds and lifecycle funds.

5. Individual Retirement Accounts (IRAs)

Traditional IRA

• Tax‑deferred growth.
• Deductible contributions depending on income and employer plan participation.
• Withdrawals before age 59½ incur a 10% penalty.

Roth IRA

• Tax‑free growth and withdrawals.
• Income limits apply: phase‑out begins at $146,000 (single) and $230,000 (married) for 2026.
• No RMDs — ideal for estate planning.

Backdoor Roth IRA

For high earners exceeding income limits:

1. Contribute to a Traditional IRA.
2. Convert to a Roth IRA.
3. Pay taxes on converted amount.

6. Self‑Employed Retirement Options

SEP IRA

• Employer contributes up to 25% of compensation.
• Flexible annual contributions.
• No employee contributions.

SIMPLE IRA

• Employers match up to 3% of salary.
• Lower administrative costs than 401(k).

Solo 401(k)

• For self‑employed individuals with no employees.
• Combines employee and employer contributions — up to $69,000 total.
• Allows Roth option and loans.

7. Catch‑Up Contributions for 2026

For investors aged 50+:

• 401(k), 403(b), 457(b): +$8,000 catch‑up.
• Ages 60–63: “Super catch‑up” up to $11,250 if plan allows.
• IRA: +$1,000 catch‑up.

These expanded limits help late savers accelerate retirement readiness.

8. Asset Allocation in Retirement Accounts

The Bucket Strategy

Divide assets by time horizon:

• Bucket 1 (0–3 years): Cash and short‑term bonds.
• Bucket 2 (3–10 years): Intermediate bonds and dividend stocks.
• Bucket 3 (10+ years): Growth stocks and ETFs.

This approach balances liquidity and long‑term growth.

40–50	70%	25%	5%
50–60	60%	35%	5%
60+	50%	40%	10%

9. Investment Options Within Retirement Accounts

Bonds

• Stabilize portfolio and provide predictable returns.
• Use high‑quality corporate or Treasury ETFs.

10. Tax Optimization Strategies

Tax Diversification

Hold both Traditional and Roth accounts to hedge future tax uncertainty.

Asset Location

• Place tax‑inefficient assets (bonds, REITs) in tax‑deferred accounts.
• Keep tax‑efficient assets (ETFs, stocks) in taxable accounts.

Roth Conversions

Convert Traditional IRA funds to Roth during low‑income years to minimize taxes.

Avoid Early Withdrawals

Withdrawals before age 59½ incur a 10% penalty plus income tax.

11. Managing Retirement Accounts After Leaving a Job

Options

1. Leave funds in old 401(k) — if low fees and good options.
2. Roll over to new employer’s plan — consolidates accounts.
3. Roll over to IRA — more investment flexibility.
4. Cash out — avoid unless necessary; triggers taxes and penalties.

Rollover Tips

• Use direct rollovers to avoid withholding.
• Compare fees and fund options before transferring.

Fee Type	Description	Typical Range
Expense Ratio	Fund management cost	0.03%–1.00%
