What accounts can I use to save for retirement in the US?

Retirement savings in the US can look complicated the first time you sign up for a workplace plan, so this FAQ for first-timers starts with the short answer. Most people save through two main routes: an employer plan such as a 401(k), 403(b), governmental 457 plan or the federal Thrift Savings Plan (TSP), and an individual retirement arrangement (IRA) that you open yourself. Both come with annual contribution limits set by the Internal Revenue Service (IRS), and both offer tax advantages in exchange for keeping money invested for the long term.

For 2026, the IRS says employees can contribute up to $24,500 to a 401(k), 403(b), governmental 457 plan or the TSP, up from $23,500 for 2025. The annual IRA contribution limit rises to $7,500, up from $7,000. Savers aged 50 and over can add catch-up contributions on top of those amounts.

Workplace plans are the starting point for many people. A 401(k) is offered by many private employers, a 403(b) is common at schools, hospitals and non-profits, a governmental 457 plan is offered by many state and local governments, and the Thrift Savings Plan is the federal government's plan for its employees and members of the uniformed services. The IRS groups these together when it sets the elective deferral limit, which is why the same $24,500 figure applies to all of them for 2026.

You choose a percentage of each paycheck to contribute, and the money goes in through payroll. Depending on the plan, you may be able to choose traditional (pre-tax) contributions, which can lower your taxable income now, or Roth contributions, which are made with after-tax pay but can come out tax-free later if the rules are met. Some employers also add matching or other contributions to your account.

An IRA is an account you open yourself with a bank, brokerage or other provider. A traditional IRA may give you a deduction depending on your income and whether you or your spouse are covered by a workplace plan, while a Roth IRA is funded with after-tax money and has income limits on who can contribute. The IRS says the income ranges for deductible traditional IRA contributions, Roth IRA eligibility and the Saver's Credit all increased for 2026; check the IRS pages for your exact figures.

Smaller employers sometimes offer a SIMPLE IRA or SIMPLE 401(k) instead. The IRS's Notice 2025-67 raises the general SIMPLE contribution limit from $16,500 to $17,000 for 2026. If you are self-employed, look into plans designed for business owners as well, and compare fees before you pick a provider. Our comparison walks through the trade-offs.

Readers evaluating Retirement savings should separate marketing claims from the actual rule text that governs their account or product. When two summaries disagree, the governing document or statute wins. If a rule depends on your age, filing status, or income band, re-check it when any of those facts change. Life events quietly move people across thresholds they last reviewed years earlier.

How much can I contribute in 2026?

For employees in 401(k), 403(b), governmental 457 plans and the TSP, the elective deferral limit is $24,500 for 2026. That is the total of your own contributions across these types of plans in the year, not per account, so if you change jobs mid-year, keep track of what you deferred at your old employer.

The IRS also sets an overall defined contribution plan limit that covers your contributions plus your employer's. Its cost-of-living table shows that limit rising from $70,000 for 2025 to $72,000 for 2026. Most first-timers will never get close to this, but it explains why employer contributions don't count against your personal $24,500 limit.

For IRAs, the 2026 limit is $7,500. That limit is shared across your traditional and Roth IRAs combined, so you can split it between them but can't put $7,500 into each. Contributions for a tax year can generally be made up to the tax filing deadline for that year, which gives you a few extra months to top up.

To see what these limits could mean over decades, try our and Small differences in the amount you save each month, and the fees you pay, can add up to large differences by retirement age.

A useful habit is to write down your goal, time horizon, and cash buffer before you change any election related to Retirement savings. Decisions made during a stressful week are the ones people reverse later at a cost. Educational explainers like this one cannot replace personalized advice for complex situations such as divorce orders, inherited accounts, or cross-border tax residency. Escalate those cases to a qualified professional.

What are catch-up contributions?

Catch-up contributions let older savers put in more. For 2026, the IRS says the catch-up limit for employees aged 50 and over in most 401(k), 403(b), governmental 457 plans and the TSP rises to $8,000, up from $7,500 for 2025. That means participants aged 50 and older can generally contribute up to $32,500 in 2026.

Under a change made by the SECURE 2.0 Act of 2022, a higher catch-up limit applies to employees aged 60, 61, 62 and 63 who participate in these plans. For 2026, the IRS says that higher catch-up limit remains $11,250 instead of the $8,000 figure.

IRAs have their own catch-up amount. SECURE 2.0 added an annual cost-of-living adjustment to the IRA catch-up limit for people aged 50 and over, and the IRS says it rises to $1,100 for 2026, up from $1,000 for 2025.

Catch-up contributions are optional. If you started saving late, they can help you close a gap, but they're most useful when combined with a realistic budget so you aren't pulling money back out of your plan later. Our can help you see your take-home pay and find room in your budget.

How do I get started as a first-timer?

Step one: find out what your employer offers. Ask HR or check your benefits portal for the plan type, whether there's an employer match, how long vesting takes, and which investment options are available. If there's a match, many people aim to contribute at least enough to receive the full match, because it's part of your pay package.

Step two: pick a contribution rate you can sustain. You don't need to hit the $24,500 or $7,500 limits in your first year. Starting with a modest percentage and increasing it each time you get a raise is a common, manageable approach.

Step three: choose investments. Many plans offer target-date funds, which adjust the mix of stocks and bonds as you approach a chosen retirement year. Whatever you choose, look at the expense ratio, since fees are charged every year. For a deeper look at spreading risk, read

Step four: check whether you qualify for the Saver's Credit, a tax credit for lower- and moderate-income savers. The IRS says the income ranges for the credit increased for 2026, so check the current thresholds on IRS.gov before you file.

Step five: review once a year. Confirm your beneficiaries, check that your contribution rate still fits your budget, and look at whether you're on track. Leaving money in the plan until retirement matters, because early withdrawals can bring taxes and, in many cases, an additional tax. More guides are at
