7 Retirement Accounts You Should Know About

Most people know they're supposed to save for retirement. Far fewer know which accounts to use — or why it matters so much. The difference between choosing the right retirement account and just parking money somewhere can mean hundreds of thousands of dollars by the time you stop working. And that gap doesn't come from some genius investment strategy. It comes from understanding the rules and using the right tools from the start.

There are seven categories of retirement accounts worth knowing, and each one operates on its own logic. Some reward you with a tax break today. Others let your money grow and withdraw completely tax-free. Some are reserved for teachers and government workers. One can technically do all three things at once. The alphabet soup — 401k, IRA, SEP, 403b, 457b — sounds complicated, but once you understand the basic framework behind each account, the whole system clicks into place.

The rules aren't random. Every account type was created to solve a specific problem: giving workers a tax-efficient way to set money aside for later, often with help from employers or the government. The Internal Revenue Service adjusts contribution limits almost every year to keep pace with inflation, which means the numbers in 2026 are different from what they were even 12 months ago. Staying current on those limits is one of the most practical things a retirement saver can do.

This guide walks through all seven account categories — what they are, who qualifies, how the tax treatment works, and what to watch out for. Whether you're just starting out or looking to squeeze more out of accounts you already have, understanding these seven types is the foundation everything else gets built on.

Traditional IRA: The Classic Tax-Deferred Move

A traditional IRA is one of the most accessible retirement accounts available. Anyone with earned income can open one, and depending on your income and whether you have a workplace plan, contributions may be fully tax-deductible. In 2026, the contribution limit is $7,500, with a $1,100 catch-up for people 50 and older. The money grows tax-deferred until you withdraw it in retirement, at which point it's taxed as ordinary income.

The deduction phase-out matters a lot here. If you or your spouse has a 401k at work, the IRS starts limiting the deduction once income crosses certain thresholds — for single filers in 2026, the phase-out begins at $81,000. Above $91,000, no deduction is available, though contributions are still allowed. Starting at age 73, the IRS requires annual withdrawals called required minimum distributions, calculated using IRS life expectancy tables and your prior year-end account balance.

What is the traditional IRA contribution limit for 2026?

The limit is $7,500 for people under 50. Those 50 and older can contribute an additional $1,100 as a catch-up contribution, bringing the total to $8,600 for the year.

Who can deduct traditional IRA contributions?

Anyone without access to a workplace retirement plan can generally deduct the full contribution. If a workplace plan exists, the deduction phases out above certain income thresholds — $81,000 to $91,000 for single filers in 2026.

When do required minimum distributions start for a traditional IRA?

Required minimum distributions begin at age 73. The amount is calculated each year by dividing the prior December 31 account balance by an IRS life expectancy factor. Missing a deadline can trigger a 25% penalty on the amount not taken.

Roth IRA: Pay Taxes Now, Withdraw Tax-Free Later

The Roth IRA flips the traditional model on its head. You contribute after-tax dollars, so there's no deduction upfront — but every dollar of growth and every qualified withdrawal comes out completely tax-free. No income tax on the gains, no required minimum distributions, and you can pull out contributions (not earnings) at any time without penalty. For younger savers expecting to be in a higher tax bracket at retirement, the Roth often wins on paper.

In 2026, the Roth IRA contribution limit is $7,500, same as the traditional. But Roth accounts come with an income ceiling: single filers with a modified adjusted gross income above $168,000 can't contribute at all, and the phase-out begins at $153,000. High earners who want in can use a backdoor Roth IRA — a two-step process of making a nondeductible traditional IRA contribution and then converting it to Roth. One finance rule that trips people up is the five-year rule: earnings from a Roth account aren't penalty-free until the account has existed for at least five years and the owner is at least 59 and a half.

What are the Roth IRA income limits for 2026?

Single filers can make full contributions with a MAGI below $153,000. The phase-out runs from $153,000 to $168,000, and above that, no direct Roth contribution is allowed. Married couples filing jointly hit their phase-out range between $242,000 and $252,000.

What is the Roth IRA five-year rule?

Earnings from a Roth IRA can only be withdrawn tax-free and penalty-free after the account has been open for at least five years and the owner is 59 and a half or older. The five-year clock starts January 1 of the tax year the first contribution is made.

Can high earners still contribute to a Roth IRA?

Yes, through a backdoor Roth IRA. The strategy involves contributing to a nondeductible traditional IRA and then converting it to Roth. The pro-rata rule applies if you have other pre-tax IRA balances, which can trigger a partial tax bill on the conversion.

401(k) Plans: The Workplace Savings Workhorse

The 401k is the most widely used retirement savings account in America, and for good reason. In 2026, employees can contribute up to $24,500 — far more than an IRA allows — and many employers sweeten the deal with matching contributions. Typical formulas match 50 cents on the dollar up to 6% of salary, effectively handing employees free money they'd otherwise leave behind. Nearly 96% of companies that offer a 401k now include a Roth 401k option, which follows the same after-tax rules as a Roth IRA but without the income limits.

Vesting is one area that catches people off guard. Employer contributions don't always belong to the employee immediately. Cliff vesting schedules grant 100% ownership after a set period — often three years. Graded schedules release ownership in increments. Leave before you're fully vested and you forfeit the unvested portion. The catch-up contribution for workers 60 to 63 jumped to $11,250 in 2026 under SECURE 2.0, and a new rule this year requires high earners making over $150,000 in FICA wages to route catch-up contributions into Roth accounts only.

What is the 401k contribution limit in 2026?

The employee deferral limit is $24,500 for workers under 50. Those 50 to 59 and 64 and older can contribute an additional $8,000. Workers aged 60 to 63 get a higher catch-up of $11,250, for a total of $35,750.

What happens to a 401k when you leave a job?

Options include rolling it into a new employer's plan, rolling it into an IRA, leaving it with the old plan if the balance is above $5,000, or cashing it out — which triggers income taxes plus a 10% penalty for those under 59 and a half.

What is 401k vesting?

Vesting determines how much of the employer's contributions are actually yours if you leave the job. Employee contributions are always 100% vested immediately. Employer match contributions may be subject to a cliff or graded schedule, with full ownership often taking two to six years.

SEP IRA & Solo 401(k): Power Tools for the Self-Employed

Self-employed workers and small business owners need retirement accounts too — and the options available to them are genuinely impressive. A SEP IRA (Simplified Employee Pension) allows contributions of up to 25% of net compensation, capped at $72,000 in 2026. There are no employee deferrals — only employer contributions — and every eligible employee must receive the same percentage. The paperwork is minimal compared to a traditional 401k, which makes the SEP IRA a go-to for solo freelancers and small firms with just a handful of workers.

The solo 401k — also called an individual 401k — lets self-employed workers contribute as both employer and employee. The employee deferral portion is $24,500 in 2026, and the employer profit-sharing side can bring total contributions up to $72,000. That dual structure gives solo operators significantly more room than a SEP IRA at lower income levels. Both plans allow Roth contribution options in some setups, and both grow tax-deferred until withdrawals begin in retirement.

What is a SEP IRA and who can open one?

A SEP IRA is a retirement plan for self-employed individuals and business owners. Any sole proprietor, partnership, LLC, or S-corp can set one up. Contributions are employer-only, capped at 25% of each eligible employee's compensation or $72,000 in 2026, whichever is less.

What is a solo 401k and how does it differ from a SEP IRA?

A solo 401k allows the self-employed to contribute as both employer and employee, enabling higher contributions at lower income levels compared to a SEP IRA. It's only available to business owners with no full-time employees other than a spouse.

Can a self-employed person have both a SEP IRA and a solo 401k?

Not simultaneously for the same business, though someone with both a day job and self-employment income may be able to maintain separate accounts. The key is that total contributions across all plans can't exceed the annual IRS limits.

403(b) & 457(b): The Accounts Teachers Deserve to Know About

If you work in public education, healthcare, government, or a nonprofit, your retirement account is almost certainly a 403b or 457b — not a 401k. The 403b works very similarly to a 401k: contributions are made pre-tax, the money grows tax-deferred, and distributions in retirement are taxed as ordinary income. The 2026 employee contribution limit is $24,500, with an $8,000 catch-up for those 50 and older. A unique feature of the 403b is the 15-year service catch-up, which allows certain long-tenured nonprofit employees to make additional contributions of up to $3,000 per year, subject to lifetime limits.

The 457b is where things get interesting. Offered mainly to state and local government employees and some nonprofit workers, the 457b has its own separate contribution limit — $24,500 in 2026 — that operates independently of the 403b. Workers who have access to both plans can contribute the maximum to each, potentially sheltering $49,000 in tax-advantaged accounts in a single year. Unlike 401k and 403b plans, the 457b allows penalty-free withdrawals after separation from service, regardless of age — a meaningful advantage for anyone planning to retire early.

What is the difference between a 403b and a 401k?

A 403b is the public-school and nonprofit equivalent of a 401k. Both have the same basic contribution limits in 2026, but 403b plans may carry higher investment fees and offer the unique 15-year service catch-up provision that 401k plans don't include.

Who qualifies for a 457b plan?

State and local government employees, including teachers, firefighters, and police officers, are the primary eligible group. Certain highly compensated employees of tax-exempt nonprofits may also have access to a nongovernmental 457b plan, though withdrawal rules differ significantly.

Can you contribute to both a 403b and a 457b in the same year?

Yes. Because 457b contribution limits are completely separate from 403b and 401k limits, eligible employees can max out both — contributing up to $24,500 to each plan in 2026, for a combined total of $49,000 before catch-up contributions.

Work with these accounts to achieve FIRE (financial independence, retire early).

Pension Plans & Defined Benefit: Guaranteed Income for Life

A pension is the original retirement plan — one where the employer does all the heavy lifting. Under a traditional defined benefit plan, the company funds the account, manages the investments, and promises a specific monthly payout in retirement calculated from a formula involving salary history, years of service, and an accrual rate. If you put in 30 years and the plan uses a 2% accrual rate, you might retire with 60% of your final average salary coming in every month, for life.

Pensions have largely disappeared from the private sector — the U.S. Bureau of Labor Statistics reported that only about 15% of private-sector workers had access to one as of recent data — but they remain common in government employment, where around 74% of workers still participate. For those who do have a pension, key decisions include whether to take a lifetime annuity or a lump-sum distribution and how to coordinate the pension with Social Security and other retirement accounts. Required minimum distributions apply to pension payments just as they do to IRA withdrawals, adding another layer of tax planning to consider.

How is a pension benefit calculated?

Most formulas multiply three numbers together: years of credited service, final average salary (often based on the last three to five years), and the plan's accrual rate, typically between 1.5% and 2.5%. The resulting monthly figure is what the employer pays for life.

What is the difference between a pension and a 401k?

A pension is a defined benefit plan — the employer funds it and guarantees a set monthly income. A 401k is a defined contribution plan — the employee funds it and the retirement income depends entirely on contributions made and investment performance.

Should you take a pension lump sum or monthly payments?

The right answer depends on life expectancy, other income sources, and personal risk tolerance. Monthly payments offer security and longevity protection; the Pension Benefit Guaranty Corporation insures them up to $93,477 per year in 2026. A lump sum gives flexibility but puts all the investment risk on you.

HSA as a Retirement Tool: The Triple-Tax-Advantage Secret

Most people think of a health savings account as a way to pay for doctor visits. Financial planners think of it as one of the best retirement accounts that exists. The HSA is the only account that offers a triple tax benefit: contributions are tax-deductible (or pre-tax through payroll), growth is tax-free, and withdrawals for qualified medical expenses are completely tax-free. In 2026, individuals can contribute up to $4,400, and families can put in up to $8,750, with a $1,000 catch-up for those 55 and older.

To open an HSA, you must be enrolled in a qualifying high-deductible health plan — which means accepting higher out-of-pocket costs in exchange for lower premiums. The real strategy for retirement savers is to pay current medical costs out of pocket when possible, let the HSA balance grow invested, and preserve those funds for healthcare expenses in retirement. After age 65, the 20% penalty for non-medical withdrawals disappears entirely, leaving only ordinary income tax — making the HSA function like a traditional IRA for general expenses, but without any required minimum distributions.

Who can contribute to an HSA?

Anyone enrolled in a qualifying high-deductible health plan can contribute. In 2026, an HDHP must have a minimum deductible of $1,650 for individuals or $3,300 for families. Medicare recipients cannot contribute to an HSA.

What makes the HSA a retirement account?

The triple tax benefit — deductible contributions, tax-free growth, tax-free withdrawals for medical expenses — makes the HSA more tax-efficient than any other retirement account for healthcare spending. After 65, it doubles as a general savings vehicle taxed like a traditional IRA.

How should an HSA be invested for retirement?

Most financial advisors recommend maintaining enough cash to cover the annual deductible, then investing the rest in diversified, low-cost funds — similar to how a long-term 401k would be invested. The HSA has no required minimum distributions, which gives it particular flexibility in retirement income planning.
