Where you hold investments can matter almost as much as what you hold. In the United States, several account types offer tax advantages for retirement and health savings. Understanding how they differ helps you decide where your next dollar of savings should go. Contribution limits, income limits and other figures change regularly, so check the current numbers on IRS.gov before acting.

Employer plans: the 401(k) and similar accounts

A 401(k) is a workplace retirement plan offered by many private employers; 403(b) and 457(b) plans serve similar roles for nonprofit and government workers. Contributions are made through payroll.

Individual retirement accounts (IRAs)

An IRA is opened by the individual at a bank, brokerage or other provider, usually with a much wider choice of investments than an employer plan.

Traditional IRA

Contributions may be tax-deductible depending on your income and whether you or your spouse are covered by a workplace plan. Growth is tax-deferred, and withdrawals are generally taxed as ordinary income.

Roth IRA

Contributions are made with after-tax money and are not deductible. Qualified withdrawals of earnings can be tax-free once you meet the age and holding-period rules. Eligibility to contribute directly is phased out at higher income levels.

Rollovers

When you leave a job, you can often move a 401(k) balance into an IRA or a new employer's plan. A direct rollover between providers generally avoids withholding and the risk of missing deadlines.

Health savings accounts (HSAs)

An HSA is available only to people covered by a qualifying high-deductible health plan. It offers three potential tax benefits: contributions can be pre-tax or deductible, growth is not taxed, and withdrawals used for qualified medical expenses are tax-free. Unused balances roll over from year to year, and many providers allow the money to be invested. Withdrawals for non-medical purposes are taxed and, before a certain age, may also face a penalty.

Rules that apply across accounts

Traditional or Roth?

The choice often comes down to whether you expect your tax rate to be higher now or in retirement. Traditional contributions reduce taxes today; Roth contributions can reduce taxes later. Many savers split contributions between both to diversify their future tax treatment, especially when the future is uncertain.

A common order of priorities

A frequently discussed approach is to build an emergency fund first, contribute enough to an employer plan to receive any full match, consider an HSA if eligible, then fund an IRA or additional workplace contributions. Your situation, including debts, income and goals, may call for a different order.

Key takeaways: 401(k)s, IRAs and HSAs each offer different tax benefits. Traditional accounts defer tax, Roth accounts can make qualified withdrawals tax-free, and HSAs combine tax benefits for medical costs. Check current limits on IRS.gov and consider professional tax advice for your situation.
