Tax-Savvy Retirement: Mastering Your 401(k) Tax Implications

When it comes to investing for your financial future, understanding the tax consequences is important to growing wealth. 

Because it’s not just what you make, it’s what you keep, that counts. 

How tax savvy are you with regards to your 401(k)? 

Are you aware of the 401(k) tax implications on withdrawals? Or the real benefit of growing your savings tax-deferred? 

Keep reading for more on 401(k) tax implications and how they may or may not impact your future.

#1 Tax-Deferred Contributions

Contributions to a traditional 401(k) are made before taxes are withheld, which reduces your taxable income. 

This means you don’t pay income taxes on the contributions immediately.

You get a tax break for every dollar that you invest into your 401(k) with pre-tax dollars. 

For example, if you earn $50,000 per year and put 3% of your pay into your 401(k), your investment in your 401(k) would be $1,500.

This $1,500 drops your taxable income down to $48,500.

In some cases, it is even possible for your 401(k) contributions to push you into a lower tax bracket, which may result in paying a lower tax rate.

#2 No Deductions on Tax Returns

Unlike other retirement accounts, you do not need to deduct 401(k) contributions on your tax return. 

The contributions are already taken out of your paycheck before taxes are applied.

This means you save money on taxes today.

Turbo Tax explains, “At the end of the year, when you receive your W-2 form that shows your earnings, you will notice that your wages subject to federal income tax are lower because of your 401(k) plan contributions.”¹

#3 FICA Taxes

Although you don’t pay income taxes on 401(k) contributions, you still pay FICA taxes on your payroll contributions.

FICA taxes fund Social Security and Medicare programs.

Your FICA taxes are calculated based on your paycheck amount, which includes your 401(k) contribution.

Keep in mind that even though your taxes go toward funding Social Security and Medicare, you will likely still need more money during retirement to cover costs.

Do not plan to rely solely on Social Security and Medicare.

#4 Tax-Deferred Growth

The investments within your 401(k) grow tax-deferred, meaning you don’t pay taxes on the earnings until you withdraw the money.

This means any income that is gained over time from your investments is tax-deferred.

When you contribute to a 401(k), your money earns interest, and that interest compounds over time – you earn returns on your returns. 

The longer your money is invested, the more it may grow.

Keep in mind that 401(k) plan participants can rebalance their assets to take advantage of potential growth opportunities, which means boosting your savings even more!

#5 Taxable Withdrawals

When you withdraw money from a traditional 401(k), it is taxed as regular income in the year you withdraw it. 

And you pay taxes on the withdrawals at your current income tax rate.

If you want to take a withdrawal from your 401(k), you need to be at least age 59½ to avoid paying an early withdrawal penalty to the IRS.

These withdrawals are subject to ordinary income tax on the amount you withdraw plus a 10% early withdrawal penalty.

#6 Roth 401(k) Contributions

With a Roth 401(k), your contributions are taxed when they go into the plan.

Contributions to a Roth 401(k) are made after income taxes are withheld, so you pay taxes on the contributions upfront. 

However, once your money is invested, your contributions and any earnings grow tax-free and you will not be taxed when you withdraw money from your Roth 401(k) plan. 

Plus, all withdrawals made during retirement are tax-free – including contributions and earnings. 

This may provide significant savings for those expecting to be in a higher tax bracket during retirement.

#7 Tax Benefits in Retirement

When you start withdrawing funds during retirement, you’ll need to pay taxes on both the contributions and the earnings, and they are subject to ordinary income tax rates.

However, the tax benefits of a 401(k) plan are designed to help you save for retirement. 

By deferring taxes until retirement, you may be in a lower tax bracket than you would have been when you initially made the contributions.

This results in a lower tax bill on withdrawals.

#8 Employer Contributions

Employer contributions to a 401(k) are generally not taxable to you when made, but you will pay taxes on them when you withdraw the money.

Employee matching contributions are tax-deferred, but these matching contributions are taxed when you withdraw money in retirement.

Your 401(k) company match counts toward your total contribution limit.

#9 Catch-up Contributions

Employees with 401(k)s can contribute up to $23,000 for 2024.

For those 50 and older, there is an additional catch-up contribution limit, which may help prepare for retirement.

For 2024, those ages 50 and older, can utilize catch-up contributions up to $7,500 – for a total of $30,500.

#10 Early Withdrawals

Withdrawing money from a 401(k) before age 59½ may result in penalties and taxes on the withdrawals.

The IRS requires automatic withholding of 20% of a 401(k) early withdrawal.

Along with the withholding taxes, the IRS will also hit you with a 10% penalty if you’re under the age of 59½ on all funds withdrawn when you file your tax return.

The amount withdrawn will also be taxed as ordinary income for the year the money was taken out, which could push you into a higher tax bracket and force you to pay even more taxes.

Let’s say you’re under 59½ and you withdraw $15,000 from your 401(k). 

You will wind up having 20% plus the penalty withheld, leaving you with only about $10,500 of the $15,000 early withdrawal.
