When you may improve your contributions annually, it’s doable the account in any other case falls on the again burner.

However for some excessive earners, there may be room in your 401(okay) to multiply your retirement financial savings annually—you simply have to know the place to look. Many plan sponsors give staff the choice to make after-tax contributions, which can be transformed to Roth, resulting in tax-free withdrawals in retirement (we’ll get into the specifics later).

Let’s take a better have a look at how 401(okay)s work, what after-tax contributions are, and learn how to leverage them to extend your retirement financial savings.

Half 1: The Fundamentals of Your 401(okay)

A 401(okay) is an employer-sponsored retirement account that provides staff a tax-advantaged method to save for retirement. Referred to as a “outlined contribution plan,” a 401(okay) allows staff and employers to contribute to the account.

Workers typically select a set share of their pay to defer into the plan. The funds are robotically deferred to the 401(okay) plan in your behalf. Relying on the plan design, you’ll have a selection in how your contributions are invested.

401(okay) and Taxes

Typically instances, your contributions to your 401(okay) are taken out of your paycheck earlier than taxes. As such, they’re aptly named “pre-tax contributions.” The quantity you contribute to your 401(okay) in pre-tax contributions will cut back your taxable revenue for the yr.

Conversely, you’ll have the choice to contribute to a Roth 401(okay) as an alternative. If that’s the case, your contributions won’t decrease your taxable revenue for the yr. The trade-off? The funds in a Roth 401(okay) develop tax-deferred, and certified distributions are tax-free as nicely (together with each the principal quantity plus earnings).

For a Roth withdrawal to qualify for the tax-free therapy, you will need to have opened and made your first contribution to the account at the least 5 years in the past and meet one of many following standards:1

• You’re 59.5 or older
• You’re thought-about disabled, as outlined by the IRS
• You’re a beneficiary of an inherited account

The IRS limits the quantity of pre-tax or Roth contributions you’re capable of make yearly to your 401(okay) and different tax-advantaged retirement accounts.

For 2025, the deferral restrict is $23,500 per taxpayer. When you’re over 50, you can be allowed to make catch-up contributions. These begin at $7,500 and improve to $11,250 for workers between the ages of 60 and 63 (this “tremendous” catch-up contribution is new as of 2025).

Right here’s what the pre-tax contribution limits appear like, primarily based in your age:2

• As much as age 49: $23,500
• Ages 50-59: $31,000
• Ages 60-63: $34,750
• Age 64 and above: $31,000

The funds in both your conventional 401(okay) or Roth 401(okay) will develop tax-deferred, which means you gained’t should pay tax (capital beneficial properties or unusual revenue tax) on the earnings annually. This enables your cash to remain invested and develop uninterrupted between when the contributions are made and whenever you withdraw (presumably in retirement).

When you attain age 59.5, you could be allowed to make penalty-free withdrawals out of your 401(okay). Remember, in the event you attempt to withdraw earlier than then, you’ll be hit with an early withdrawal penalty—except you are taking out a mortgage out of your 401(okay) or meet one of many IRS’s exceptions.

Withdrawals out of your conventional 401(okay) are topic to unusual revenue tax—bear in mind, up till now, neither the unique contributions nor the earnings have been taxed. When you attain age 73 (or age 75, beginning in 2033), you can be required to withdraw a minimal quantity out of your pre-tax 401(okay) annually. These are referred to as “required minimal distributions” or RMDs, and so they’re calculated primarily based in your account steadiness by the top of the earlier calendar yr and the IRS uniform lifetime desk. ROTH 401ks are usually not topic to RMD guidelines.

Take Benefit of Employer Matching

Many employers incentivize staff to contribute to their 401(okay) by providing what’s referred to as “employer matching.” For each greenback or wage share an worker contributes, the employer will match it (often as much as a certain quantity).

For instance, let’s assume your employer matches your contributions by 50% as much as 3% of your wage. When you earn $200,000, 3% of your wage is $6,000. When you contribute 3% of your wage, they’ll chip in a further $3,000 matching, primarily based on the figures above.

Employer matching is basically free cash. Most staff will profit from contributing to their 401(okay)s at the least sufficient to max out the matching contributions (however ideally, maxing out the IRS annual contribution limits as nicely).

One word on employer matching: Typically, employers will implement a vesting schedule for employer matching. Do you have to go away the corporate earlier than the vesting interval has ended, you could lose all or a few of your employer matching contributions. You’ll, nevertheless, be entitled to something you contributed to the account, regardless of how lengthy you stick with the corporate.

Half 2: After-Tax Contributions

To date, we’ve targeted on pre-tax and ROTH contributions and the way they decrease your tax invoice now, whereas serving to you develop funds for retirement. The catch is, pre-tax and ROTH contributions are restricted yearly by the IRS (in the event you’re below 50, the cap is $23,500 for 2025).

For top earners, particularly, the pre-tax contribution might really feel low, and you want you would save extra. When you’re interested by growing contributions past the pre-tax restrict, your plan might can help you make after-tax contributions as nicely.

Simply as they sound, after-tax contributions to your 401(okay) are robotically deferred out of your paycheck to your 401(okay). Whereas these further contributions will assist you develop your retirement financial savings additional, they don’t decrease your taxable revenue for the yr (as your pre-tax contributions would).

To find out the utmost after-tax deferral to a 401(okay) plan, you’ll have to first know the full quantity you and your employer are allowed to contribute collectively to a defined-contribution retirement plan. In 2025, this quantity is $70,000, although this restrict is adjusted yearly.3

If we assume you max out your pre-tax contributions at $23,500 and your employer supplied no matching, the utmost quantity you would contribute in after-tax contributions is a further $46,500.

Now, let’s say your employer gives a $10,000 matching contribution. Your pre-tax contribution of $23,500 plus the extra $10,000 employer matching brings your whole as much as $33,500. As an alternative of $46,500, now you can contribute as much as $36,500 in after-tax contributions.

Let’s take a better search for 2025:

The entire contribution restrict stays the identical, even in the event you’re eligible for catch-up contributions. Utilizing the identical instance as above, let’s have a look at it once more, assuming you’re 62 and maxing out pre-tax contributions at $34,750:

Half 3: Changing After-Tax to Roth

Whereas after-tax contributions to a standard 401(okay) have related traits to Roth contributions, they aren’t precisely the identical. The earnings on after-tax contributions in a standard 401(okay) will nonetheless be topic to unusual revenue tax.

Right here’s a better have a look at the distinction between after-tax and Roth 401(okay) contributions:

Roth accounts have the tax benefit over after-tax contributions, since they can help you get pleasure from doubtlessly tax-free withdrawals in retirement. For that cause, in the event you’re capable of make after-tax contributions to your 401(okay), you may wish to take it a step additional and full a Roth conversion—basically transition these funds from the standard 401(okay) right into a Roth account.

There are a number of doable methods to do that, relying on what your employer’s plan gives.

Possibility #1: In-plan Roth conversion

The only choice is to instantly roll the after-tax {dollars} right into a Roth 401(okay). That is solely doable, nevertheless, in case your plan permits for “in-plan conversions.” Assuming they do, it is best to be capable to pretty simply convert the after-tax {dollars} to the Roth account. Simply bear in mind, in case your after-tax contributions earn any progress earlier than changing to the Roth account, you’ll owe unusual revenue tax within the yr the conversion takes place. The excellent news is, some corporations enable automated in-plan conversions. The after-tax {dollars} can be robotically rolled right into a Roth account, which might get rid of the opportunity of further earnings previous to conversion.

For instance, say you contribute $30,000 in after-tax contributions to your conventional 401(okay). On the finish of the yr, you resolve to do an in-plan conversion and transition that $30,000 to your plan’s Roth 401(okay). Earlier than the conversion occurs, nevertheless, the funds accumulate a further $2,000 in earnings. You’ll be required to pay unusual revenue tax on these earnings. However as soon as the conversion is full, every little thing within the account will develop tax-deferred, and certified withdrawals shall be tax-free.

You might be able to roll the funds right into a Roth IRA as soon as the Roth conversion is full. You may wish to roll them over as soon as you permit your employer, for instance, so you’ll be able to proceed making contributions or consolidate accounts.

Possibility #2: Roth IRA rollover with no in-plan conversion

In case your plan doesn’t enable for in-plan conversions, your choices get a bit extra difficult. Finally, in the event you’d prefer to convert your after-tax contributions to a Roth account, you’ll want to make use of a Roth IRA—however with out an in-plan conversion choice, this switch might rely as a withdrawal from the 401(okay).

In case your plan tracks contribution sources (which means it separates out pre-tax versus after-tax contributions), you may need the choice to roll out solely the after-tax contributions from the 401(okay) right into a Roth IRA. You would additionally roll the pre-tax contributions and any progress into a standard IRA, which might not create a taxable occasion.

For instance, say you permit your present employer and have gathered $500,000 in your 401(okay). Your plan supplier does observe contribution sources and means that you can take a full distribution of the funds as soon as employment is terminated. When you needed to keep away from triggering a tax invoice, you would roll the funds into the next IRAs:

• $250,000 of pre-tax contributions roll into a standard IRA
• $150,000 in Roth contributions roll right into a Roth IRA
• $100,000 in after-tax contributions roll into that very same Roth IRA

In case your plan doesn’t can help you individually rollover funds primarily based on the contribution supply, you should still be capable to rollover right into a Roth IRA. The catch is, you’ll be hit with a tax invoice for the pre-tax contributions and untaxed earnings.

In both case, you could wish to communicate to your plan administrator, a monetary advisor, and/or a tax skilled to debate the potential instant and long-term influence of changing your funds to a Roth 401(okay) or IRA.

Half 4: Issues for Workers
