Saving for retirement can become complicated once different accounts, tax rules and contribution limits enter the picture. Workplace plans such as 401(k)s can provide tax advantages and employer contributions, while individual retirement accounts offer another way to build long-term savings. Understanding how each option works can also help savers avoid unnecessary taxes and fees.
Choosing a retirement account
Traditional 401(k) contributions are generally made before income taxes, reducing taxable income for the year while allowing investments to grow tax-deferred. Taxes are then due when money is withdrawn, while employers may also offer matching contributions. IRAs provide another route for retirement investing through assets such as stocks, bonds and mutual funds. Traditional IRA contributions may qualify for a federal tax deduction depending on income and workplace retirement coverage, with taxes deferred until withdrawal.
Roth IRAs work differently because contributions are made with after-tax money and are not deductible. Qualified withdrawals can later be tax-free, making the timing of taxation an important consideration when choosing between accounts. Workers without employer-sponsored plans may also have access to state programs. California’s CalSavers, for example, automatically enrolls eligible workers in a Roth IRA while allowing them to opt out or change their contribution rate.
Limits and withdrawal costs
Contribution limits can determine how much savers place into tax-advantaged accounts each year. For 2026, workers younger than 50 can contribute up to $24,500 to 401(k), 403(b) and 457 plans, while eligible older workers can make additional catch-up contributions. Combined traditional and Roth IRA contributions are capped at $7,500 for 2026, rising to $8,600 for people aged 50 or older. Public-sector workers may have additional choices, including 403(b) and 457 plans.
Taking retirement money early can create extra costs. Many distributions before age 59½ can face an additional 10% federal tax, although exceptions apply for circumstances including permanent disability, certain higher-education expenses and qualifying military service. Investment and administrative fees can also eat into your savings over time. Comparing costs, tax treatment, employer matching and withdrawal rules can therefore be just as important as deciding how much to contribute.
