How to Choose the Right 401(k) Provider For You

Identify Your Needs

As you can see, there are plenty of options for 401(k) providers that range from large-scale solutions for companies with over a thousand employees and smaller solutions that make managing 401(k)s for small teams very accessible.

The first step in choosing the right or 401(k) provider is identifying what you need for your team. If you want a small and straightforward solution, you may want to work with a provider who is an expert at working with small business owners and providing a limited suite of services.

On the other hand, you may want a comprehensive provider who offers all of these services if you want payroll, human resources, accounting, and reporting all to integrate together.

Shop Around

Once you identify what functionality and services you want from a 401(k) provider, you should shop around and identify companies that offer the most transparent fee structures and lowest cost to maintain.

The most crucial factor for a smaller company is to make sure that you get the most bang for your buck with your 401(k) provider. You don't want to pay excessive fees for a provider that charges above-average transaction costs for you and your employees.

Likewise, if you are in charge of a large enterprise, focus on finding a partner who can seamlessly integrate with your existing systems to avoid mass confusion and potential disruptions for your teams.

401(k) FAQs:

What Happens To A 401(k) When You Quit?

In the event you move on to a better job, but have money sitting in your old employer's 401(k) account, you may be wondering: what happens to that money?

If you have less than $1,000 in the account, your old employer may cash out the account and send you a check for the balance. Maintaining employee investment accounts cost money, and they most likely do not want to pay for the maintenance fee. If your account has between $1,000 and $5,000, Your employer might perform an involuntary cash-out, which means they will move the funds from their 401(k) account into an IRA.

If you have more than $5,000 in the account, you could leave it alone to grow, but if you want to take it with you, you couldn't either roll it over into a new 401(k) if your new employer offers one or convert it into an IRA account.

Can You Contribute To A 401(k) Without An Employer?

The short answer is no; you cannot contribute to a 401(k) without an employer as an individual. 401(k)s require sponsors, which is why they are called employer-sponsored retirement plans.

However, there are two significant exceptions:

  1. If you are self-employed or a business owner, you can set up a solo 401(k) for yourself, which gives you most of the benefits of a traditional employer-sponsored 401(k).

  2. If you previously were contributing to a 401(k) at your old employer, you can keep your balance in that account, but you cannot make new contributions to a 401(k) housed at a previous employer.

How Much Money Should I Contribute To My 401(k)?

Most financial advisors recommend saving at least 10% of your gross salary and contributing to your 401(k) at the beginning of your saving money. Some advisors even recommend socking away up to 20% of your gross salary if you can't afford it to help you reach your retirement goals.

One of the most essential factors in deciding how much you should contribute to your 401(k) is if your employer offers a match. Many employers provide a 401(k) match to match a dedicated percentage of your contribution or a portion of your contribution up to a stated amount.

For example, if your employer explicitly will match up to 4% of your salaried contributions, this is essentially free money, bringing your overall contribution to 8%.

Can I have 2 401(k) plans?

Suppose you have two different jobs that both offer 401(k) retirement plans. You may be wondering if you are eligible to contribute to both retirement plans to maximize your retirement savings.

The short answer is yes, you can contribute to multiple 401(k) plans simultaneously, but this may affect your tax liability around tax time. Since the IRS allows individuals to deduct up to $17,000 in 401(k) contributions annually, you may wonder if this applies to both of your accounts.

However, the IRS uses the entire $17,000 as a cumulative amount, so if you plan to contribute to multiple 401(k)s, remember you can only deduct $17,000 in total, and not per account.

401(k) vs. IRA

A 401(k) is an employer-sponsored retirement plan that your employer can issue, or you can open it for yourself if you are self-employed. 401(k)s are considered tax-deferred plans because you contribute to them through payroll deductions and pay the taxes on them when you take withdrawals during retirement.

Individual Retirement Accounts (IRAs) are managed solely by an individual and are usually funded with post-tax dollars. The benefit of an IRA is that you pay taxes upfront, the money can grow in its account tax-free until retirement, and your withdrawals will also be tax-free.

Can I have a 401(k) and an IRA?

Yes - you can contribute to both a 401(k) and an IRA. 401(k)s are employer-sponsored retirement plans, whereas IRAs are personal retirement accounts that are not related to your employer.

Many people contribute to both 401(k)s and IRAs and maximize their retirement savings if they are eligible.

Remember that 401(k)s have much higher contribution limits of $19,500, but the IRS limits IRA contributions to $6,000 or $7,000 per year.
