Once you first onboarded together with your firm, you have been probably given the selection to take part in a 401(ok). When you may improve your contributions every year, it’s doable the account in any other case falls on the again burner.

However for some excessive earners, there could be room in your 401(ok) to multiply your retirement financial savings every year—you simply must 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(ok)s work, what after-tax contributions are, and leverage them to extend your retirement financial savings.

Half 1: The Fundamentals of Your 401(ok)

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

Staff usually select a set proportion of their pay to defer into the plan. The funds are mechanically deferred to the 401(ok) plan in your behalf. Relying on the plan design, you might have a selection in how your contributions are invested.

401(ok) and Taxes

Typically occasions, your contributions to your 401(ok) 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(ok) in pre-tax contributions will cut back your taxable earnings for the 12 months.

Conversely, you might have the choice to contribute to a Roth 401(ok) as a substitute. If that’s the case, your contributions won’t decrease your taxable earnings for the 12 months. The trade-off? The funds in a Roth 401(ok) develop tax-deferred, and certified distributions are tax-free as effectively (together with each the principal quantity plus earnings).

For a Roth withdrawal to qualify for the tax-free remedy, you have to have opened and made your first contribution to the account no less than 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(ok) and different tax-advantaged retirement accounts.

For 2025, the deferral restrict is $23,500 per taxpayer. When you’re over 50, you’ll 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(ok) or Roth 401(ok) will develop tax-deferred, which means you received’t need to pay tax (capital good points or bizarre earnings tax) on the earnings every year. This permits your cash to remain invested and develop uninterrupted between when the contributions are made and once you withdraw (presumably in retirement).

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

Withdrawals out of your conventional 401(ok) are topic to bizarre earnings 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’ll be required to withdraw a minimal quantity out of your pre-tax 401(ok) every year. These are referred to as “required minimal distributions” or RMDs, they usually’re calculated primarily based in your account stability by the tip of the earlier calendar 12 months and the IRS uniform lifetime desk. ROTH 401ks should not topic to RMD guidelines.

Take Benefit of Employer Matching

Many employers incentivize staff to contribute to their 401(ok) by providing what’s referred to as “employer matching.” For each greenback or wage proportion an worker contributes, the employer will match it (normally 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 an extra $3,000 matching, primarily based on the figures above.

Employer matching is actually free cash. Most staff will profit from contributing to their 401(ok)s no less than sufficient to max out the matching contributions (however ideally, maxing out the IRS annual contribution limits as effectively).

One be aware on employer matching: Typically, employers will implement a vesting schedule for employer matching. Must you go away the corporate earlier than the vesting interval has ended, you might lose all or a few of your employer matching contributions. You’ll, nonetheless, be entitled to something you contributed to the account, irrespective 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 (when you’re underneath 50, the cap is $23,500 for 2025).

For top earners, particularly, the pre-tax contribution could really feel low, and you would like you can save extra. When you’re occupied with growing contributions past the pre-tax restrict, your plan could permit you to make after-tax contributions as effectively.

Simply as they sound, after-tax contributions to your 401(ok) are mechanically deferred out of your paycheck to your 401(ok). Whereas these extra contributions will provide help to develop your retirement financial savings additional, they don’t decrease your taxable earnings for the 12 months (as your pre-tax contributions would).

To find out the utmost after-tax deferral to a 401(ok) plan, you’ll must 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 provided no matching, the utmost quantity you can contribute in after-tax contributions is an extra $46,500.

Now, let’s say your employer offers 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 a substitute 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 when 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 conventional 401(ok) have related traits to Roth contributions, they aren’t precisely the identical. The earnings on after-tax contributions in a conventional 401(ok) will nonetheless be topic to bizarre earnings tax.

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

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

There are just a few doable methods to do that, relying on what your employer’s plan affords.

Possibility #1: In-plan Roth conversion

The best choice is to right away roll the after-tax {dollars} right into a Roth 401(ok). That is solely doable, nonetheless, in case your plan permits for “in-plan conversions.” Assuming they do, it’s best to have the ability to pretty simply convert the after-tax {dollars} to the Roth account. Simply consider, in case your after-tax contributions earn any progress earlier than changing to the Roth account, you’ll owe bizarre earnings tax within the 12 months the conversion takes place. The excellent news is, some firms enable automated in-plan conversions. The after-tax {dollars} could be mechanically rolled right into a Roth account, which might remove the potential for extra earnings previous to conversion.

For instance, say you contribute $30,000 in after-tax contributions to your conventional 401(ok). On the finish of the 12 months, you determine to do an in-plan conversion and transition that $30,000 to your plan’s Roth 401(ok). Earlier than the conversion occurs, nonetheless, the funds accumulate an extra $2,000 in earnings. You’ll be required to pay bizarre earnings 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 will likely be tax-free.

You could possibly 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 may 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 slightly extra difficult. Finally, when you’d wish 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 could rely as a withdrawal from the 401(ok).

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(ok) right into a Roth IRA. You would additionally roll the pre-tax contributions and any progress into a conventional IRA, which might not create a taxable occasion.

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

• $250,000 of pre-tax contributions roll into a conventional 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 permit you to individually rollover funds primarily based on the contribution supply, you should still have the ability 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 might wish to communicate to your plan administrator, a monetary advisor, and/or a tax skilled to debate the potential rapid and long-term influence of changing your funds to a Roth 401(ok) or IRA.

Half 4: Concerns for Staff

Maybe the largest hurdle in supercharging your 401(ok) with after-tax contributions is figuring out what your plan really permits. Do they assist after-tax contributions? What about in-plan conversions?

As soon as you establish what’s out there and doable inside your account, it’s good to determine how and once you’d wish to make after-tax contributions. Your plan could provide the choice to make automated after-tax contributions with each paycheck, so you may “set it and neglect it” all year long. Or, you might must manually request to contribute after-tax {dollars} to the account—particularly when you’re solely planning to take action every now and then.

Assessment Your Money Circulate First

When you’re contemplating making after-tax contributions to your 401(ok), overview your present money circulation and different financial savings methods first.

Diverting extra of your paycheck to your retirement account will, naturally, cut back your take-home pay.

If not, this is probably not the correct time to pursue after-tax contributions.

It’s additionally value contemplating your different choices for saving for retirement or long-term targets. For instance, a conventional brokerage account can also be funded with after-tax {dollars}, and it has no contribution restrict or age restrictions on withdrawals. So long as you maintain the belongings for greater than a 12 months, you might even profit from extra favorable long-term capital good points tax remedy. You can too preserve extra independence and management over how your funds are invested, since 401(ok) plan choices are sometimes restricted.

That being stated, dedicating extra funds in direction of your retirement accounts will help construct lasting monetary safety, so long as you’re not sacrificing your rapid monetary well-being within the course of.

Think about Your Tax Bracket Now vs. Later
