How Does a Pre-Tax 401(k) Plan Function?

Nov 29, 2023 By Triston Martin

Congress mandated retirement savings schemes like 401(k)s to assist, motivate and facilitate workers' financial planning for later life. Significant tax savings are available when contributing to a traditional 401(k) plan. You save enough, too, so that you may retire without worrying about money.

The Basics of 401(k) Deductions

Your taxable income will go down immediately since 401(k) contributions are often made using pre-tax cash, so you'll benefit from this directly. Income tax will be calculated on a lower amount. Donations won't wholly eat away at our take-home earnings.

They depend on what's left over after withholding is determined, which is why they are done first. You'll end up paying less in taxes because of the reduction in your taxable income that results from these pre-tax payments.

Usually, the amount you give will cost you less after considering the income taxes you avoid paying. The money you put into a 401(k) isn't taxed until you withdraw it in retirement. Additionally, your employer may contribute to your plan.

Traditional 401k (k)

Employee contributions to a standard 401(k) plan are taken from "gross" income or salary received before taxes are taken off. Thus, the sum of the employee's contributions for the year is deductible from the employee's income for tax purposes. Neither the employee's contribution nor investment gains are subject to taxation until the funds are withdrawn, often upon retirement.

Roth 401(k) (k)

When employees participate in a Roth 401(k), their contributions are taken out of their salary after taxes have already been paid. Thus, no tax benefit is available in the year of the donation.

However, some companies don't provide their employees with the choice of a Roth IRA. If the standard 401(k) and the Roth option are available, the employee can choose whichever is most beneficial to them. Up to the yearly limit, they can put money into both.

Investing In A 401(k) Plan

But, a 401(k) is a retirement savings plan in which participants make predetermined yearly contributions. The employee and the employer can contribute to the account up to the IRS maximum (IRS).

Compared to the more common defined-benefit pension, the standard in the United States, a defined-contribution plan offers several distinct advantages. Many people rely on assistance to retire comfortably, in which their employers promise a set amount of money each year.

Contribution Caps

Inflation, a measure of the rate at which economic prices are growing, is factored into the monthly adjustments to the maximum amount that employees and employers can contribute to a 401(k) plan. The maximum amount an employee can contribute in a year in 2022 is $20,500.

On the other hand, people who are 50 or older can make a catch-up payment of $6,500. The maximum employee contribution for 2023 is $22,500 per year for individuals under 50. Also, people who are 50 or older can contribute a $7,500 "catch-up" payment.

Organizational Compatibility

When determining an employer's matching contribution, a few different methods may be used. An employer may contribute up to a specified proportion of an employee's pay, such as 50 cents for every dollar contributed by the employee. It is a bit of legal advice from financial experts that workers max out their 401(k) contributions each year.

Pairing 401(k) Roth and Traditional Contributions (k)

An employee who has access to both standard and Roth 401(k) plans at work can choose how to allocate their contributions between the two accounts (k). To avoid exceeding the limit for either form of invoice (say, $20,500 for individuals under age 50 in 2022 or $22,500 in 2023), they can open both accounts.

How Do You Get Paid From Your 401(k)?

Your 401(k) contributions will be invested by the options you pick from those provided by your employer. As was said up top, these choices generally consist of a range of stock and bond mutual funds in addition to target-date funds that aim to mitigate the impact of market fluctuations on your retirement savings.

In addition to the amount you put in a year and whether or not your employer matches it, the growth of your retirement fund also depends on the performance of your assets and the length of time before you retire.


A 401(k) plan is a type of company retirement plan that allows employees to save and invest up to a certain amount each year in preparation for their retirement. You can choose between a conventional 401(k) and a Roth 401(k). When contributing to a standard 401(k), you can defer paying taxes on those funds until they are withdrawn from the account.
