Everything You Need to Know About 401(K) Plan Administrator


What is a 401(k)?

Starting with the most basic question, what is a 401(k)? It is basically a retirement savings plan that employers offer to their employees. In simpler terms, it is a company-sponsored retirement account where the employees contribute to the plan with their income, while employers may match contributions. The reason to choose a 401(k) is that it gives employees relaxation over tax on the amount of money they have contributed to the plan. The term 401(k) comes from a section of the tax code i.e., from subsection 401(k), and thus this name comes into being.

How It Works:

What happens in a 401(k) plan is that the employee agrees to pay a percentage amount of their paycheck directly into an investment account which is also linked with the employer. Through this, the percentage amount that is directed to the investment account is not shown under the name of the employee, which exempts the employee to pay income tax on that particular percentage amount.


The 401(k) plan excludes any employees that are under the age of 21 and/or those employees that have not worked for their employer for one year. It also excludes those employees that are union members and alien employees (non-residents of America or those who are not paid on a US payroll). The 401(k) plan could also exclude some other employees as well depending on the company and the legislation system.

Basic Types of 401(k) Plans:

There are 2 broad categories of 401(k) plan:

Traditional 401(k) Plan

– In the traditional 401(k) plan, the contribution is taken out of your paycheck before income taxes are collected. This will lower the taxable income. That money is then invested in mutual funds and/or other investments, and when after retirement you withdraw the amount, you have to pay ordinary income tax on the withdrawn amount.

Roth 401(k) Plan

– In the Roth 401(k) plan, the contributions are taken out after you pay income taxes. Roth 401(k) plan is highly suitable for young earners who have just begun their careers because they have lower income levels and that’s why they fall into lower tax brackets. However, for people who fall under higher tax brackets, for them, Roth 401(k) is not suitable at all.

What are The 401(k) Contribution Limits & How Employer Matching Contributions Works:

The specific terms and details vary with every 401(k) plan, but the bottom-line regulations have to be adhered to by everyone which are directed by Employee Retirement Income Security Act (ERISA). In most cases, employers match employee contributions up to a percentage of the annual income earned by the employee. To understand it more clearly, let’s assume that you earn $50,000 annually, and your employer has agreed to match 100% of your contributions each year, up to a maximum of 5% of the annual income. According to 5% of $50,000, it calculates up to $2,500 each year, so the employer is going to contribute $2,500 each year, so to maximize this benefit you must also contribute $2,500. If you contribute more than 5% of your annual income, then those contributions will be unmatched.

However, a contribution limit has been set by the Internal Revenue Service (IRS), and if your 401(k) contributions exceed the prescribed limit, you can end up being taxed twice on the excess contributions (the first time it will be taxed as your taxable income, and the second it will be taxed when you withdraw from the plan).

401(k) Vesting:

While understanding the 401(k) plan, it is important to understand the concept of vesting too. Vesting simply means ownership. An employee who is 100% vested in his balance account, means that he owns 100% of the balance in the account, and this means that the employer does not have any sort of ownership over the balance. A 100% vested account is very rare because an employer keeps a percentage of the account vested on their behalf in case the employee gets terminated, or acts in a way that is against the organizational principles.

In the beginning, the employer, and the employee both are vested into the balance account, but when the employee comes near his retirement age or near the termination of the plan, the account needs to be 100% vested for the employee, so that the employer then has no ownership over employee’s savings.

What is a 401(k) Administrator?

As stated earlier, a 401(k) plan has its roots attached to the legislation system of the country. Laws are known to be complex, they are dynamic, which makes it very difficult to monitor the plan and protect the plan in the favor of an employee. This is where 401(k) administrators enter, they help the employee to monitor and protect the plan, and ensure that the plan is working the way it should work and they assure that the plan is also following the rules.

Every 401(k) plan is different, it is supposed to be customized and yet still apply to the laws of the country. A 401(k) plan administrator pays keen attention to the retirement plan and makes sure that it is not contradicting the upholding law.

What Are the Responsibilities of a 401(k) Plan Administrator?

The word administrator refers to a person providing administration services. Administration is a continuous process, it doesn’t stop at any point, an administrator’s responsibility is to monitor the entire plan, from choosing the plan design to launching it, and even keeping track of every single transaction, therefore an administrator is also called the gatekeeper of the 401(k) plan.

Some other general duties of an administrator include:

Design: Mainly includes designing the structure of the plan and sketching the entire process of it.
Revise: With changing laws, the plan also needs to be revised constantly.
Solving issues: If any sort of issue arises, the employer needs to be notified immediately, and the issue needs to be solved as soon as possible.
Filings & Disclosures: Where legislation is involved, then immense paperwork is also involved. An administrator makes sure that all the paperwork is updated and modified timely.
Consultancy: Giving relevant suggestions and ideas and suggesting actions on unprecedented events.

Why Is It important to Choose a Good 401(k) Administrator?

A 401(k) administrator plans and monitors the entire plan, which also includes a keen attention to detail. A pro tip is that you should always go for an administrator that focuses on and handles small business clients because they will provide you with personalized attention and for them you will be an actual client and not just a number.

For a 401(k) plan it is very important to have a good administrator because with the continuous changes in laws, the plan also needs to be revised. A good administrator will be aware of the changes and they will notify the recipient immediately so that the plan could be revised accordingly. Without a good administrator, it is very challenging for the recipient to be conscious and aware of the ongoings. Furthermore, an administrator is said to be the gatekeeper, and if the gatekeeper is only troublesome, then the entire plan will come crumbling down within no time.

The Role of a 401(k) Administrator in Compliance

401(k) having its roots linked with the legislative system, it gets very difficult for the organization to manage both, the benefit of their employees, and to also stay away from any illegal or unlawful activities. Therefore, 401(k) administrators try to maintain the levels of organizational compliance and assures that the company doesn’t indulge in any sort of unlawful practices.

It is the administrator’s main duty to prevent the employee, the employer, and the entire company to commit any sort of unlawful act, knowingly or unknowingly, in accordance with the 401(k) plan. An administrator is very devoted to understanding the plan and also monitors in the favor of the company.

It is very important to hire an administrator to manage a 401(k) plan because firstly a layman can’t easily understand the language, the terms, and the specifics of the plan document, and if even a single phrase is misinterpreted it could lead to unanticipated consequences. Secondly, the reason a layman needs an administrator is that administrators are frequently notified of any changes in laws and they are even aware when the plan document needs to be amended or updated. The minute details and frequent updates are the key to a successful 401(k) plan, and an administrator tries to avoid any sort of mishap so that everything could run smoothly.

Types of 401(k)Aadministrators

There are two types of 401(k) administrators:

Third-party 401(K) Administrators

A third-party administrator (also known as TPA) is a company or an individual that is providing operational services in accordance to claim charges or employee management schemes that is under a contract with another company. The typical examples of a TPA are the types of insurance contracts, such as health insurance, car insurance, etc.

TPAs are professionals and state-licensed companies that provide comprehensive services to employers. Employers mainly hire TPAs to handle health insurance plans or car insurance plans or other employee benefit plans for their employees. This is because employers don’t have the knowledge and skills to monitor the insurance claims, therefore TPAs use their skills to help the employers.

In today’s world, many companies use the services of a TPA, for example, a hospital that provides a self-funded employee health insurance policy will use the services of a TPA so that they could control and monitor third-party claims. Similarly, car insurance also works in this manner only. Third-party Administrators are increasing day-by-day and their responsibilities and duties are also becoming more day-to-day operational basis. A TPA in 401(k) plan is an organization that is hired by the employer to run day-to-day aspects of your retirement plan.

In-house 401(K) Administrators

As the name suggests, in-house administrators are those individuals that work within the company and perform the responsibilities of an administrator. In simpler terms, it is a personal administrator of a company, in which the company is using its own employee to handle all the administration work, such as brokerage works or financing works. In this type of administrator, the company doesn’t opt for outsourcing, and they don’t get dependent on other companies or individuals to monitor their plans or manage their issues, in fact, they hire their own personal administrator.

Mainly larger companies go for in-house administration work, several factors are kept in mind for opting for this decision. In-house administration gives a lot of flexibility in the work, and the amount of attention to detail in various cases is very high. Moreover, it also gives a personalized service to the company and they also have control over the administrator’s work.

An in-house administrator in 401(k) works as a full-time personal administrator for the company. As it is very expensive to hire an administrator for smaller companies, but for large corporations, it is very much needed because of their frequently occurring legal issues and constant monitoring of their day-to-day operations.

How to Choose a 401(k) Administrator

Once you’ve decided to opt for a 401(k) plan, it is very important to hire an administrator to overlook your transactions and constantly keep you updated on happenings. However, it is also very crucial to look at several factors while choosing an administrator depending on the size of your company, the financials, etc. This will all be covered in the following in detail:

Factors to Consider When Opting For Third-Party Administrator


Cost is always a very important factor to consider when making any sort of decision. When choosing a TPA, cost is given a lot of weightage, the reason is that several companies and individuals provide the same services, and a company aims to select the one offering the best deal. Several factors are taken into consideration while choosing a TPA, such as the reputation of the company, its services, and so on. Therefore, it’s vital to make a holistic decision.

Services Offered

An administrator’s duties and responsibilities include a variety of services, some are needed by the organization whilst some are not that important. A company should be aware that while selecting a TPA, the services they offer should include all the services that are required by the company, or else it could lead to drastic results.

Investment Options

As discussed earlier that all 401(k) plans are different, their design, their structure, their assets, their financials, etc. varies tremendously from company to company. A TPA should understand the needs and priorities of the recipient, and then suggest suitable investment options that could be beneficial for the employee and employer both.

Compliance Track Record

The laws and regulations of a country keep changing, and it needs to be constantly addressed while enrolling for a 401(k) plan. The company should make sure that while selecting a TPA, they should conduct a background check that whether the TPA follows and understands the legal requirements so that in times of need the TPA could guide the company appropriately.

Customer Service

For any service you are taking, whether it be even in a restaurant, we all expect customer service to be great. While selecting a TPA, it is very important that you are being treated as a client and not as a number, because if you get personalized service, then your legal issues will be solved and managed smoothly. Always keep customer service as your highest priority.

Factors to consider When Opting For In-House Administrator

Size of your company

An in-house administrator provides you with customized services, but when hiring an in-house administrator, the size of the company matters a lot. A small company doesn’t have frequent legal issues nor needs constant monitoring of their financial transactions, but on the other hand, large corporations or MNCs have more constant usage of these services, and therefore for them hiring an in-house administrator is very important.


When having many competitors in the industry, a company needs to be very vigilant throughout. When outsourcing, the privacy of the company comes at stake, which could lead to disastrous results in the future, so to avoid these kinds of problems in the future, in-housing administration is most recommended. Through this, your privacy remains intact and the company has a watch over the administrator, which protects the private information of the company to be leaked to the outside world.


It’s very obvious that an in-house administrator is more expensive than an outsourced administrator, but it depends on the company to which factor they want to give more weightage, the budget or the customized service. For large corporations, budget is not usually an issue, because of their frequent legal issues, therefore it depends on the employer what is their budget.

Employee Needs

While selecting an in-house administrator, employee needs are also taken into consideration. An administrator has a variety of tasks on their hands, and a 401(k) plan is entirely subjected to employees. An employer will hire an in-house administrator when constant monitoring of transactions, frequent employee management policies, etc. are needed, but when the employee needs are different, as in they don’t make constant transactions, or they don’t need constant updates of their investment plans, then an in-house administrator could become very expensive to hire for a company.

How to Troubleshoot Common 401(k) Problems

For a layman, it is very difficult to understand the terms and the procedure of the 401(k) plan instantly, however, you could at least avoid these 5 common problems:

A 401(k) plan document is very lengthy and includes each and every detail of the plan, that includes the eligibility requirements, the contributions you could make, the investment details, vesting options, payout details, and so on. The administrator must explain the entire plan in detail so that you don’t miss out on any specific detail, but many administrators just go through the important parts and leave out certain particulars from the draft. It is highly advisable that you clear out all the legal language and have a clear understanding. This will help you in eliminating the guesswork.

As stated repeatedly, a country’s legislation system keeps on being updated frequently, so it is very important to update the plan when required or else it could be very devastating.

The notices and disclosures are to be distributed promptly to newly eligible employees and even existing participants. The information is very crucial to be transmitted to all the participants so that they could make the decisions accordingly about their accounts.
