Your employer contributes to a 401(k), 403(b), or SIMPLE IRA—not to your personal IRA

Your employer cannot contribute to a traditional or Roth IRA that you open on your own. Those are individual accounts, and the IRS does not allow employer money to go into them. Instead, your employer contributes to a workplace retirement plan: most commonly a 401(k), a 403(b) if you work at a nonprofit or school, or a SIMPLE IRA if your employer has fewer than 100 employees. The type of plan depends on what your employer has set up, not on what you choose.

The distinction matters because employer contributions are separate from your own contributions, they follow different rules, and they affect how much you can save overall. If your employer offers a workplace plan, that is where their money goes. If they do not offer one, they cannot contribute to your retirement savings at all.

Key Takeaways

  • Employers contribute only to workplace plans—401(k), 403(b), or SIMPLE IRA—never to personal IRAs you open yourself.
  • A 401(k) is the most common employer plan and allows both employee and employer contributions, with higher annual limits than IRAs.
  • A 403(b) works like a 401(k) but is only offered by nonprofits, schools, and certain government employers.
  • A SIMPLE IRA is used by small employers with fewer than 100 employees and has lower contribution limits than a 401(k).
  • If your employer does not offer a workplace plan, you can open your own IRA, but your employer cannot put money into it.

The 401(k): the standard workplace plan

A 401(k) is a defined-contribution plan where you choose how much to contribute from your paycheck, and your employer may match a portion of it. The employer match is optional—your employer decides whether to offer one, how much to match, and under what conditions. A common match is 50 cents for every dollar you contribute, up to 6 percent of your salary, but the terms vary widely.

In 2024, you can contribute up to $23,500 of your own money to a 401(k) per year (or $31,000 if you are 50 or older). Your employer's contribution does not count against this limit, but the total of your contributions plus the employer match cannot exceed $69,000 per year. The money is held in an account in your name, and you choose how it is invested from the options your employer's plan offers.

When you leave the job, you can roll the 401(k) into an IRA or another employer's 401(k), or leave it where it is if the balance is large enough. You cannot take the money out without penalty until you turn 59½, with narrow exceptions for hardship or separation from service.

The 403(b): for nonprofits and schools

A 403(b) works almost identically to a 401(k) but is only available to employees of nonprofit organizations, public schools, colleges, and certain government agencies. The contribution limits are the same as a 401(k)—$23,500 for 2024, or $31,000 if you are 50 or older—and your employer may offer a match.

The main practical difference is that 403(b) plans often have fewer investment options than 401(k)s, and they are sometimes administered by insurance companies rather than investment firms. If you work at a school or nonprofit and your employer offers a 403(b), that is the only workplace plan available to you; your employer will not also offer a 401(k).

Like a 401(k), you can roll a 403(b) into an IRA when you leave the job, and the same withdrawal restrictions apply.

The SIMPLE IRA: for small employers

A SIMPLE IRA is a workplace retirement plan designed for employers with 100 or fewer employees. It is simpler and cheaper for the employer to run than a 401(k), but it has lower contribution limits. In 2024, you can contribute up to $16,000 of your own money per year (or $19,500 if you are 50 or older).

Unlike a 401(k), where the employer match is optional, a SIMPLE IRA requires the employer to contribute. They must either match your contributions dollar-for-dollar up to 3 percent of your salary, or contribute 2 percent of your salary for all employees regardless of whether they contribute themselves. This means you will receive an employer contribution even if you do not put in your own money.

When you leave the job, you can roll a SIMPLE IRA into a traditional IRA or another retirement plan. There is a two-year waiting period after you first enroll before you can roll it to another plan without penalty, though this rule has exceptions.

What happens if your employer does not offer a plan

If your employer does not sponsor a 401(k), 403(b), or SIMPLE IRA, they cannot contribute to your retirement savings. You can open your own traditional IRA or Roth IRA and contribute up to $7,000 per year (or $8,000 if you are 50 or older), but the money comes entirely from you. Your employer has no role in it.

Some employers offer a payroll deduction IRA, which lets you authorize automatic transfers from your paycheck to an IRA you open yourself. This is a convenience for you, not an employer contribution—the money is still yours, and the employer is just handling the paperwork. The employer does not put any of their own money in.

How employer contributions affect your taxes

Employer contributions to a 401(k), 403(b), or SIMPLE IRA are not counted as taxable income to you in the year they are made. If you contribute $5,000 of your own money and your employer contributes $2,000, you only pay income tax on the $5,000 you earned; the $2,000 is deferred. You pay income tax on both amounts when you withdraw the money in retirement.

This tax deferral is one reason employer plans are valuable—it reduces your taxable income now and lets the money grow tax-free until withdrawal. If you have access to an employer plan with a match, taking full advantage of the match is usually the first step in retirement saving, because it is immediate, may provide money.

Vesting: when the employer contribution becomes yours

Employer contributions to a workplace plan are subject to a vesting schedule, which determines when the money actually belongs to you. Your own contributions are always 100 percent vested immediately—they are yours from day one. But the employer's contribution may not be.

A common vesting schedule is three-year cliff vesting, where you receive 0 percent of the employer contribution for the first three years, then 100 percent after three years of service. Another common schedule is graded vesting, where you become vested in 20 percent of the employer contribution each year over five years. Your employer's plan documents will specify the vesting schedule.

If you leave the job before you are fully vested, you forfeit the unvested portion of the employer contribution. For example, under three-year cliff vesting, if you leave after two years, you lose all the employer money contributed on your behalf. This is why it is important to know your vesting schedule if you are considering changing jobs.

Frequently Asked Questions

Can my employer contribute to my personal IRA?

No. Employers can only contribute to workplace plans—401(k), 403(b), or SIMPLE IRA. If you open a traditional or Roth IRA on your own, your employer cannot put money into it. You can set up a payroll deduction to transfer your own money to an IRA, but that is not an employer contribution.

What if my employer offers both a 401(k) and a SIMPLE IRA?

Employers choose one or the other, not both. A SIMPLE IRA is only used by small employers with 100 or fewer employees, and a 401(k) is used by larger employers. If you work for a company with both options, one of them is likely being phased out or the company structure has changed.

Do I have to contribute to get the employer match?

In a 401(k) or 403(b), yes—the match is conditional on your contribution. In a SIMPLE IRA, no—your employer must contribute even if you do not, though the amount may be lower if you do not contribute yourself.

What happens to my employer contributions if I get fired?

You keep the money you contributed yourself. You keep the employer contributions only if you are vested in them. If you are not yet vested, you forfeit the unvested portion. Check your plan documents or ask your HR department for your vesting schedule.

Can I roll my employer's contribution into an IRA when I leave?

Yes. When you leave a job, you can roll the entire balance of your 401(k), 403(b), or SIMPLE IRA—including both your contributions and the employer's—into a traditional IRA or another employer's plan. The rollover is not taxed if you complete it within 60 days or use a direct transfer.
