A 401(k) is the retirement account almost everyone knows about. You get one through your job, you put money in, and your employer sometimes adds a match. It's become the default way most people in the United States save for retirement.

But what happens when you don't have one?

Maybe your employer doesn't offer a plan. Maybe you own a business. Maybe you work part-time somewhere. A lot of situations can leave you without access to a 401(k).

When that happens, many people just don't save anything because they don't have any options. They think the 401(k) is the only real way to save, so they do nothing at all. That can be an expensive mistake.

You've got options. In fact, you've got good ones.

What a 401(k) Actually Does

Before we talk about alternatives, it helps to understand what makes a 401(k) useful in the first place. Once you see the mechanics, you can find similar benefits in other places.

A 401(k) is an employer-sponsored retirement plan. That means you can only get one through a company that hires you as an employee. It's the most common retirement plan in existence today, which is why everyone knows the name.

There are a couple of special things about 401(k)s. 

The tax treatment

Every 401(k) offers a pre-tax option. You put money in before it's taxed. This lowers your taxable income now and lets you invest a little more up front.

Many plans also offer a Roth option. With a Roth 401(k), you put money in after tax, and then it grows tax-free. Roth options are becoming more common each year.

So the first benefit is the tax shelter. You either get a deduction going in, or tax-free growth coming out.

The employer match

The second benefit is the match. Many employers add money to your account based on how much you contribute, up to a set percentage.

That's free money. There's no reason to leave it on the table. If your employer offers a match, take it.

The 401(k) Isn't as Magical as You Think

Here's something most people don't hear enough: the 401(k) isn't a magic account.

The tax treatment is useful. The match is useful. But take those two things away, and a 401(k) is just an investment account with rules attached.

We've been trained as a society to treat the 401(k) as the "one true path" to retirement. So when people lose access to one, they assume they've lost their only chance to save well.

What matters most is that you're saving, that you're investing that money well, and that you're on track for your goals. The account is just the container. Let's look at the containers you can use instead.

Options If You're an Employee

Let's say you're a regular employee at a company that doesn't offer a plan. Here's the order I'd think about.

Start with an IRA or Roth IRA

The IRA is usually the first stop. IRA stands for Individual Retirement Arrangement. It's a personal retirement account that you open on your own, with no employer involved.

An IRA works a lot like a 401(k) in practice. A traditional IRA lets you put money in pre-tax, so you get a deduction now and pay tax later when you withdraw. A Roth IRA works the other way. You pay tax now, and the money grows tax-free for retirement.

Both accounts have a contribution limit which is lower than 401(k) limits. And just like a 401(k), you generally can't take the money out before age 59 and a half without a penalty. That's the trade-off for the tax benefits.

The Backdoor Roth IRA

There's one twist worth knowing. High earners phase out of the ability to contribute directly to a Roth IRA.

But there's a workaround. It's called the Backdoor Roth IRA, and it lets some high earners get money into a Roth anyway.

The strategy has caveats, and it isn't right for everyone. Don't treat this as specific advice to do it. Talk to a professional who can look at your full picture first.

The HSA as a retirement tool

Your next stop might surprise you. A Health Savings Account, or HSA, can double as a retirement account.

You can only contribute to an HSA if you've got a health insurance plan that qualifies for one. But if you do, it comes with a nice set of tax benefits.

Money goes in with a deduction. It grows tax-deferred. And when you use it for qualified medical costs, you can take it out tax-free. This is why some people refer to an HSA as an account with a "triple tax benefit."

Most people treat the HSA as a spending account for this year's medical bills. But if you can pay those costs another way and leave the HSA invested, it becomes a powerful long-term account. Additionally, after age 65 it behaves more like a traditional IRA for non-medical spending, and it stays tax-free for medical costs.

The taxable brokerage account

Now we get to the most underused account of all: the taxable brokerage account.

The name scares people. Nobody wants to put money into something called "taxable." But the name only means the account has no special tax shelter. That's the one thing it gives up. In exchange, it gives you total freedom.

You can put the same investments inside a taxable account that you'd put inside a 401(k) or an IRA. Stocks, bonds, ETFs, mutual funds, and more can all go inside it. What you put in the account is what drives the growth, not the label on the account.

A taxable account has no contribution limit, no income limit, and no early withdrawal penalty. You can put in as much as you want. You can take it out whenever you want. You can invest it as aggressively as any retirement account.

That flexibility makes it a great catch-all. You can use one taxable account, or several, each for a different goal. One can be a long-term supplement to retirement. One can be a backup emergency fund. One can even be a vacation fund, since a vacation isn't urgent. If the market's down, you simply wait to spend that bucket until it recovers.

You can open a taxable account through any brokerage, or through a financial advisor if you want help investing it. It's one of the most accessible and flexible tools available, and far too many people skip right past it.

Options If You're a Business Owner

Now let's say you own your business. You don't have an employer, so you assume you've got nothing available to you. That's one of the biggest myths in personal finance.

Business owners have more options than almost anyone.

Everything above still applies to you. The IRA, the Roth IRA, the backdoor Roth, the HSA, and the taxable account are all on the table. On top of those, you've got retirement plans built for business owners.

The SEP IRA and SIMPLE IRA

Two common business plans are the SEP IRA and the SIMPLE IRA.

A SEP IRA lets you save a large amount of pre-tax money, while a SIMPLE IRA is more modest.

Both are inexpensive and easy to set up under the right conditions. Both give you a tax deduction that lowers your taxable income.

The Solo 401(k)

If you're a solo business owner, the Solo 401(k) is my favorite option, and it's often underutilized.

A Solo 401(k) is a real 401(k) that you set up for a business with no employees other than you and possibly a spouse. Even a 1099 contractor can often use one. Best of all, it can include a Roth option.

You can set up a 401(k) even with a few employees

What if you've got a small team? Say you've got one, two, or three employees.

Many owners assume they're too small for a 401(k). That isn't true. You can set one up for a business of almost any size.

A number of low-cost, high-tech platforms now make small-business 401(k) plans affordable and simple to run. These are the same kinds of platforms that advisors use with clients every day. If you've wanted a real plan for your team, the options are better than you might think.

Cash Balance Plan

There's also something called a Cash Balance Plan, which is a really good fit for Solo Business Owners with a high income.

A Cash Balance Plan is a type of defined benefit plan that often works in tandem with a Solo 401(k) and can give you very high contribution limits and the ability to set aside quite a bit of money pre-tax to lower your taxable income.

Cash Balance Plans are not as common as 401(k)s, but they can be a great fit to really optimize your options for lowering your taxable income while saving for retirement. 

Taxable accounts for business owners

Finally, don't forget the taxable account. It works just as well for business owners as it does for employees.

I keep several taxable accounts for my own family, each in a different bucket. Some are long-term, some are medium-term, and some are short-term, and each is invested to match its job.

Yes, these accounts are taxable. But you can make them very tax-efficient. When you build a taxable account for the long term, you fill it with investments that generate as little taxable income as possible along the way. You'll still pay some tax, but the burden stays small, and the flexibility more than makes up for it.

Don't Let Taxes Drive Every Decision

There's a bigger lesson hiding inside all of this.

As a society, we spend enormous energy trying to avoid taxes. Financial advisors call it "the tax tail wagging the dog." When you become obsessed with saving on taxes, you often miss better opportunities somewhere else.

Are taxes important? Yes. You should never create needless tax inefficiency, and you should always be mindful of the bill. But saving on taxes isn't always the most important goal, and it shouldn't drive every decision you make.

This is exactly why the taxable account gets ignored. People hear "taxable" and stop listening. In doing so, they walk away from an account with huge flexibility and real advantages.

Don't let a fear of taxes stand between you and progress toward your goals.

The Bottom Line

A 401(k) is a great tool for many people. But it isn't the only route to retirement, and it isn't always the best one.

If you don't have access to a 401(k), you're not stuck. Start with an IRA or Roth IRA. Consider a backdoor Roth if you're a high earner. Use an HSA as a stealth retirement account if you qualify. And don't overlook the taxable brokerage account, which may be the most flexible tool of all.

If you own a business, look at the Solo 401(k) or explore a small-business 401(k) if you've got a team, and layer taxable accounts on top for extra savings.

Don't let lack of access to a 401(k) keep you from saving and investing for retirement. You've got plenty of options to fill the gap. 

Frequently Asked Questions

Can I still save for retirement without a 401(k)?

Yes. A 401(k) is just one type of retirement account. You can save through an IRA, a Roth IRA, an HSA, a taxable brokerage account, and, if you own a business, plans like a SEP IRA or a solo 401(k). What matters most is that you save consistently and invest the money well.

What's the best 401(k) alternative for most employees?

For most employees, the IRA or Roth IRA is the natural first step. Once you max that out, an HSA and a taxable brokerage account are strong next options. The right mix depends on your income, your tax situation, and your goals.

Is a taxable account really a good place to save for retirement?

It can be. A taxable account has no contribution limit, no income limit, and no early withdrawal penalty. You can hold the same investments you'd hold in a 401(k). You'll pay some tax along the way, but with tax-efficient investments, that cost stays low, and the flexibility is hard to beat.

I own a business. What retirement plan should I use?

If you've got no employees, a solo 401(k) is often the best choice because it allows a Roth option and generous contribution limits. If you've got a small team, you can set up a low-cost small-business 401(k). A SEP IRA or SIMPLE IRA can also work, though neither offers a Roth option. An advisor can help you compare them.

What's a backdoor Roth IRA?

A backdoor Roth IRA is a strategy that lets high earners get money into a Roth IRA even when their income is too high to contribute directly. It involves specific steps and has real caveats, so it's best to work with a professional before you try it.

How much can I contribute to an IRA in 2026?

For 2026, you can contribute up to $7,500 per year if you're under 50, and up to $8,600 if you're 50 or older. Roth IRA contributions also phase out at higher income levels, starting at $153,000 for single filers and $242,000 for married couples filing jointly.

Do I lose the chance to save if my job doesn't offer a match?

No. A match is a nice bonus, but it isn't the only reason to save. You can still build significant wealth through IRAs, HSAs, and taxable accounts. Saving something is always better than saving nothing, with or without a match.
