Your employer can contribute to a 401(k), 403(b), straightforward IRA, or SEP IRA — but not to a traditional or Roth IRA you open on your own

The type of account your employer contributes to depends entirely on what your employer offers. If you have a workplace retirement plan, your employer is almost certainly contributing to either a 401(k), 403(b), straightforward IRA, or SEP IRA. Your employer cannot contribute to a traditional IRA or Roth IRA that you open yourself — those are individual accounts, and employer contributions to them are not allowed under tax law.

The distinction matters because it changes how much your employer can contribute, whether you can borrow from the account, and what happens to the money if you leave your job. Understanding which type you have tells you what rules explore to your specific account.

Key Takeaways

  • 401(k) plans are the most common employer plan, and employers can contribute up to 25% of your salary, with a combined employee-plus-employer limit of $69,000 per year in 2024.
  • 403(b) plans work like 401(k)s but are only available through schools, hospitals, nonprofits, and some government employers.
  • straightforward IRAs allow employers to contribute either 3% of your salary automatically or match up to 3% of what you contribute.
  • SEP IRAs let employers contribute up to 25% of your salary with no matching requirement, and are common among self-employed people and small businesses.
  • You can tell which plan you have by checking your employee handbook, your pay stub, or asking your HR department directly.

401(k) plans: the standard employer retirement account

A 401(k) is a defined-contribution plan, meaning your employer sets aside money in an account with your name on it. Your employer can contribute in two ways: they can match a percentage of what you contribute (the most common approach), or they can make a non-elective contribution regardless of whether you contribute anything.

The employer match is usually 3% to 6% of your salary, though it varies by company. If your employer offers a 4% match and you earn $50,000 per year, they contribute $2,000 annually. If you contribute less than 4%, they contribute only on what you put in. Some employers contribute more generously or offer both a match and an additional profit-sharing contribution.

In 2024, the combined limit for employee and employer contributions together is $69,000 per year (or $76,500 if you are 50 or older). This means if you contribute $23,000, your employer can contribute up to $46,000 in the same year, as long as the total does not exceed the limit. Your employer's contributions are always vested when ready — you own them the moment they are deposited, even if you leave the job the next day.

403(b) plans: retirement accounts for nonprofits and schools

A 403(b) plan operates almost identically to a 401(k), with one key difference: it is only available through schools, hospitals, nonprofits with 501(c)(3) status, and certain government employers. If you work at a public school, a university, a large hospital system, or a national charity, your employer likely offers a 403(b) rather than a 401(k).

Your employer can contribute through a match (usually 3% to 6% of salary) or a non-elective contribution. The annual contribution limits are the same as a 401(k): $69,000 combined in 2024. One practical difference is that 403(b) plans sometimes have fewer investment options than 401(k)s, and they historically allowed only annuities; most now allow mutual funds as well.

If you move from a 403(b) employer to a 401(k) employer, you can roll your 403(b) balance into the new 401(k), though some plans restrict this. Check with your new employer's HR department before you leave your old job.

straightforward IRAs: employer plans for small businesses

A straightforward IRA is designed for businesses with 100 or fewer employees. The employer must contribute, but the contribution is limited. The employer either makes a 3% match on what employees contribute, or contributes 2% of salary for all employees regardless of whether they contribute themselves (called a non-elective contribution).

The annual limit for straightforward IRAs is much lower than 401(k)s: $16,000 per year in 2024 (or $19,500 if you are 50 or older). This limit applies to combined employee and employer contributions. If your employer contributes 3% and you contribute 10%, the total is 13% of your salary, but only up to the $16,000 annual cap.

straightforward IRAs are easier and cheaper for small employers to administer than 401(k)s, so they are common in small firms, family businesses, and professional practices. If you leave a job with a straightforward IRA, you can roll it into another IRA or into a 401(k) at your new employer, though there is a two-year restriction if you want to avoid taxes — money moved within two years of when you first enrolled in the straightforward IRA may be subject to a higher early-withdrawal penalty.

SEP IRAs: the self-employed and small-business option

A SEP IRA (Simplified Employee Pension) is an IRA that an employer funds on behalf of employees. It is popular among self-employed people, freelancers, and small business owners because the employer contribution is flexible — there is no requirement to contribute every year, and the amount can vary.

An employer can contribute up to 25% of an employee's compensation, with an annual limit of $69,000 in 2024. Unlike a straightforward IRA, there is no employee contribution — the employer funds the entire account. If you are self-employed and have no employees, you can open a SEP IRA and contribute up to 25% of your net self-employment income (after adjusting for self-employment tax).

SEP IRAs are straightforward to set up and require minimal paperwork compared to 401(k)s. However, if you leave a job where your employer contributed to a SEP IRA, you own that money outright and can roll it into another IRA or 401(k) at your next employer.

How to find out which plan your employer offers

The fastest way to learn which retirement plan you have is to check your most recent pay stub — it usually lists the plan name and the employer contribution amount. If it is not there, your employee handbook or benefits summary should list the plan type and the contribution formula.

If you cannot find the information in those places, contact your HR department or benefits administrator directly. They can tell you the plan type, the current employer contribution rate, your vesting schedule (how long you must work before the contributions are fully yours), and whether you can borrow from the account. Some employers also provide a summary document called a Summary Plan Description, which outlines all the rules.

If you are newly hired, your employer should have provided plan information during onboarding. If you did not receive it, ask for it — you have a legal right to this information.

What happens to employer contributions when you leave your job

Employer contributions are always yours to keep, but the timing depends on your employer's vesting schedule. Vesting means the point at which you own the money outright. Most employers use either when ready vesting (you own the contribution the day it is deposited) or a graded schedule (you own a percentage each year, typically becoming fully vested after three to six years).

When you leave your job, you can roll your balance into an IRA or into a new employer's 401(k) plan. You have 60 days to complete the rollover without triggering taxes or penalties. If you do not roll it over, the money stays in your old employer's plan until you withdraw it, at which point taxes and potential penalties explore.

Some employers allow you to leave money in their plan indefinitely if your balance is above a certain threshold (often $5,000). Others require you to move it within a set timeframe. Check with your old employer's benefits department to understand your options.

Frequently Asked Questions

Can my employer contribute to my personal IRA?

No. Employers cannot contribute to traditional IRAs or Roth IRAs that you open on your own. If your employer wants to contribute to your retirement, they must set up a workplace plan like a 401(k), 403(b), straightforward IRA, or SEP IRA. You can have both a workplace plan and a personal IRA, but they are separate accounts with separate contribution limits.

What if my employer offers multiple retirement plans?

Some larger employers offer both a 401(k) and a straightforward IRA, or a 401(k) and a SEP IRA. You can usually participate in only one plan per employer. Your HR department can tell you which plans are available and which one you are enrolled in. If you have a choice, compare the contribution limits, match formulas, and investment options.

Does my employer have to contribute to my retirement account?

No. Employers are not required by law to offer any retirement plan at all, and if they do offer one, they are not required to make contributions. However, if they set up a 401(k), 403(b), or straightforward IRA, they must follow specific rules about contributions and vesting. A SEP IRA requires the employer to contribute if they contribute for themselves, but they can skip years if they choose.

What if I do not contribute anything — does my employer still contribute?

It depends on the plan. In a 401(k) or 403(b) with a match, your employer contributes only if you contribute first. In a straightforward IRA, your employer must contribute either a 3% match or a 2% non-elective contribution regardless of whether you contribute. In a SEP IRA, your employer contributes a percentage of your salary whether you contribute or not.

Can I move my employer contributions to a different account?

Yes. You can roll employer contributions from a 401(k), 403(b), straightforward IRA, or SEP IRA into another IRA or into a new employer's 401(k) plan. The rollover must happen within 60 days to avoid taxes and penalties. Some plans allow direct rollovers, where the money moves from one institution to another without passing through your hands, which is the safest method.
