What Is a 401(a) Plan?

A 401(a) plan is an employer-sponsored money-purchase retirement plan that allows dollar or percentage-based contributions from the employer, the employee, or both. The sponsoring employer establishes eligibility and the vesting schedule. The employee can withdraw funds from a 401(a) plan through a rollover to a different qualified retirement plan, a lump-sum payment, or an annuity.

Understanding a 401(a) Plan

There are a variety of retirement plans that employers can offer their employees. Each comes with different stipulations, restrictions, and some are better suited for certain types of employers.

A 401(a) plan is a type of retirement plan made available to those working in government agencies, educational institutions, and non-profit organizations. Eligible employees who participate in the plan include government employees, teachers, administrators, and support staff. A 401(a) plan’s features are similar to a 401(k) plan, which are more common in profit-based industries. 401(a) plans do not allow employees to contribute to 401(k) plans, however.

If an individual leaves an employer, they do have the option of transferring the funds in their 401(a) to a 401(k) plan or individual retirement account (IRA).

Employers can form multiple 401(a) plans, each with distinct eligibility criteria, contribution amounts, and vesting schedules. Employers use these plans to create incentive programs for employee retention. The employer controls the plan and determines the contribution limits.

To participate in a 401(a) plan, an individual must be 21 years of age and have been working in the job for a minimum of two years. These conditions are subject to vary.

Contributions for a 401(a) Plan

A 401(a) plan can have mandatory or voluntary contributions, and the employer decides if contributions are made on an after-tax or pre-tax basis. An employer contributes funds to the plan on an employee’s behalf. Employer contribution options include the employer paying a set amount into an employee’s plan, matching a fixed percentage of employee contributions, or matching employee contributions within a specific dollar range.

The majority of voluntary contributions to a 401(a) plan are capped at 25% of an employee’s annual pay.

Investments for a 401(a) Plan

The plan gives employers more control over their employees’ investment choices. Government employers with 401(a) plans often limit investment options to only the safest and most secure options to minimize risk. A 401(a) plan assures a certain level of retirement savings but requires due diligence by the employee to meet retirement goals.

Vesting and Withdrawals for a 401(a) Plan

Any 401(a) contributions an employee makes and any earnings on those contributions are immediately fully vested. Becoming fully vested in the employer contributions depends on the vesting schedule the employer sets up. Some employers, especially those who offer 401(k) plans, link vesting to years of service as an incentive for employees to stay with the company.

The Internal Revenue Service (IRS) subjects 401(a) withdrawals to income tax withholdings and a 10% early withdrawal penalty unless the employee is 59½, dies, is disabled, or rolls over the funds into a qualified IRA or retirement plan through a direct trustee-to-trustee transfer. 

Qualifying for Tax Credits

Employees who contribute to a 401(a) plan may qualify for a tax credit. Employees can have both a 401(a) plan and an IRA at the same time. However, if an employee has a 401(a) plan, the tax benefits for traditional IRA contributions may be phased out depending on the employee’s adjusted gross income.

401(a) vs. 401(k) Plans

A 401(a) plan is similar to a 401(k), another type of employer-sponsored plan that provides a tax advantage for retirement investments. The main difference is who participates: while 401(k) plans are intended for private sector employees, 401(a) plans are directed towards employees of government bodies, educational institutions, and charitable organizations. These plans also tend to offer fewer, more conservative investment options than those found in a 401(k) plan.

If you work in the private sector, you can contribute to a 401(k) plan after one year. But if your employer offers a 401(a) plan, it takes two years.

There are also important rule differences between the two types of plans. With a 401(k) plan, participation is voluntary, and the employee can decide how much money to contribute towards the plan so long as it is below the legal limit. Employers may match a portion of the employee’s contribution, but many do not.

But in a 401(a) plan, employers can make it mandatory for their employees to participate. But employers are also required to contribute to their employees’ accounts. They can also decide whether the 401(a) plan is to be funded with pre-tax or after-tax dollars.

Tips for a 401(a) Plan

As with other types of retirement plans, it is important to understand the rules and fees associated with a 401(a) before making a significant contribution. This caution can help reduce your costs and expenses further down the line.

Here are some ways to make the most out of a 401(a) or any other tax-advantaged retirement account:

• Understand the Rules. As with other tax-advantaged retirement accounts, there are strict rules about what you can do with the money in a 401(a) account. If you take money out before you reach age 59½, you may face a 10% penalty, except for certain emergency expenses. It is important to understand the rules for holding and closing your account to avoid unexpected tax implications.
• Understand the fees. In addition to taxes, there are also fees associated with a 401(a) account that are used to offset the administrative costs of maintaining your investment account. High plan fees can easily eat into your portfolio gains, so it is important to talk to your employer and understand how much the plan will actually cost you.

The Bottom Line

A 401(a) plan is a type of tax-advantaged account that allows public-sector employees to save for retirement. These plans typically offer fewer investment options than other types of plans, and they are also relatively low-risk. Although employers can make participation mandatory, there are may also be a tax credit for those who contribute to a 401(a).

What Is an After-Tax Contribution?

An after-tax contribution is money paid into a retirement or investment account after income taxes on those earnings have already been deducted. When opening a tax-advantaged retirement account, an individual may choose to defer the income taxes owed until after retiring, if it is a traditional retirement account, or pay the income taxes in the year in which the payment is made, if it is a Roth retirement account.

Some savers, mostly those with higher incomes, may contribute after-tax income to a traditional account in addition to the maximum allowable pre-tax amount. They don’t get any immediate tax benefit. This commingling of pre-tax and post-tax money takes some careful accounting for tax purposes.

Understanding After-Tax Contributions

In order to encourage Americans to save toward their retirement years, the government offers several tax-advantaged retirement plans such as the 401(k) plan, offered by many companies to their employees, and the IRA, which anyone with earned income can open through a bank or a brokerage.

Most, but not all, people who open a retirement account can choose either of two main options:

• The traditional retirement account allows its owner to put “pre-tax” money in an investment account. That is, the money is not subject to income tax in the year it is paid in. The saver’s gross taxable income for that year is reduced by the amount of the contribution. The IRS will get its due when the account holder withdraws the money, presumably after retiring.
• The Roth account is the “after-tax” option. It allows the saver to pay in money after it is taxed. That is more of a hit to the person’s immediate take-home income. But after retirement, no further taxes are owed on the entire balance in the account. The Roth 401(k) option (referred to as a designated Roth option) is newer, and not all companies offer them to their employees. Earners above a set limit are not eligible to contribute to a Roth IRA account.

Post-Tax or Pre-Tax?

The post-tax Roth option offers the attraction of a retirement nest egg that is not subject to further taxes. It makes the most sense for those who believe they may be paying a higher tax rate in the future, either because of their expected retirement income or because they think taxes will go up.

In addition, money contributed post-tax can be withdrawn at any time without a fat IRS penalty being imposed. (The profits in the account are untouchable until the account holder is 59½.)

On the downside, the post-tax option means a smaller paycheck with every contribution into the account. The pre-tax or traditional option reduces the saver’s taxes owed for the year the contributions are made, and it is a smaller hit to current income.

The downside is, withdrawals from this type of retirement fund will be taxable income, whether it’s money that was paid in or profits the money earned.

After-Tax Contributions and Roth IRAs

A Roth IRA, by definition, is a retirement account in which the earnings grow tax-free as long as the money is held in the Roth IRA for at least five years. Contributions to a Roth are made with after-tax dollars, and as a result, they are not tax-deductible. However, you can withdraw the contributions in retirement tax-free.

Both post-tax and pre-tax retirement accounts have limits on how much can be contributed each year:

• The annual contribution limit for both Roth and traditional IRAs is $6,000 for tax year 2022 (increasing to $6,500 in 2023). Those aged 50 and over can deposit an additional catch-up contribution of $1,000.
• The contribution limit for Roth and traditional 401(k) plans is $20,500 for 2022 (increasing to $22,500 in 2023), plus $6,500 for those age 50 and above.

Early Withdrawal Tax Penalty

As noted, the money deposited in a post-tax or Roth account, but not any profits it earns, can be withdrawn at any time without penalty. The taxes have already been paid, and the IRS doesn’t care.

But if it’s a pre-tax or traditional account, any money withdrawn before age 59½ is fully taxable and subject to a hefty early withdrawal penalty.

An account holder who changes jobs can roll over the money into a similar account available at the new job without paying any taxes. The term “roll over” is meaningful. It means that the money goes straight from account to account and never gets paid into your hands. Otherwise, it can count as taxable income for that year.

Special Considerations

As noted above, there are limits to the amount of money that a saver can contribute each year to a retirement account. (Actually, you can have more than one account, or a post-tax and a pre-tax account, but the total contribution limits are the same.)

Withdrawals of after-tax contributions to a traditional IRA should not be taxed. However, the only way to make sure this does not happen is to file IRS Form 8606. Form 8606 must be filed for every year you make after-tax (non-deductible) contributions to a traditional IRA and for every subsequent year until you have used up all of your after-tax balance.

Since the funds in the account are separated into taxable and non-taxable components, figuring the tax due on the required distributions is more complicated than if the account holder had made only pre-tax contributions.
