Maximize the employer match first
If your employer offers a match, contribute at least enough to capture the full match.
This is essentially free money and an immediate return on your contribution. Treat the match as the highest-priority part of your retirement plan before increasing contributions for other goals.
Choose the right tax strategy
Many plans offer both traditional (pre-tax) and Roth (after-tax) options.
Traditional contributions reduce taxable income today and grow tax-deferred; withdrawals are taxed later. Roth contributions don’t reduce current taxable income but allow tax-free qualified withdrawals. Use tax diversification—holding both types across accounts—to give yourself flexibility in retirement and control over future tax bills.
Build a long-term asset allocation
Your mix of stocks, bonds, and other assets should reflect your time horizon and risk tolerance. Younger savers generally benefit from a higher stock allocation for growth potential, while those nearing retirement often shift toward more conservative investments to protect capital. Consider target-date funds for a hands-off solution that automatically adjusts allocation over time, or create a custom allocation using low-cost index funds.

Keep an eye on fees and fund quality
Fees compound over time and can significantly reduce retirement balances.
Compare expense ratios, administrative fees, and any plan-level costs. Favor low-cost index or passive funds when they meet your needs. If your plan’s options are limited or expensive, consider contributing enough to get the employer match and investing additional savings in an IRA or taxable account.
Rebalance and monitor periodically
Markets shift asset mixes away from your target allocation. Rebalancing—selling portions of outperforming assets and buying others—helps maintain risk levels and enforces discipline.
Schedule a review at least annually or enable automatic rebalancing if your plan offers it.
Know your rollover and job-change options
When you change jobs you typically can: leave the balance in your former employer’s plan, roll it into your new employer’s plan, roll it into an IRA, or cash it out (usually a poor choice because of taxes and penalties). Rolling to an IRA or a new plan can simplify management and may reduce fees, but evaluate investment choices and protections (like creditor protection) before deciding.
Understand plan features and limitations
Some plans offer loans, hardship withdrawals, or automatic enrollment and escalation. Loans can provide short-term access to funds, but they reduce retirement balances and can carry risks if you leave your job. Automatic escalation—raising contributions gradually each year—helps increase savings without requiring ongoing effort. Designate beneficiaries and update them after major life events.
Tax and withdrawal considerations
Traditional 401(k) withdrawals are taxed as ordinary income, while Roth qualified withdrawals are tax-free. Required minimum distributions may apply to traditional accounts, so plan your withdrawal strategy in retirement to manage taxes efficiently.
Action checklist
– Contribute enough to get the full employer match
– Pick a tax mix (traditional vs Roth) that fits your tax outlook
– Choose a diversified, low-cost allocation aligned with your goals
– Check fees and replace high-cost options when possible
– Rebalance periodically or use automatic rebalancing
– Review beneficiary designations and plan rules on rollovers/loans
Regularly reviewing your 401(k) and making small adjustments over time can dramatically improve retirement outcomes.
