What is 401k?

401k is a workplace retirement plan where employees and employers can make retirement contributions. These retirement plans can be one of the easiest and most effective ways to save for retirement. As an employee, you can automatically contribute your 401k directly through your company payroll. You can choose the percentage of your salary toward your retirement savings. Most 401k plans will provide you with multiple investment options in stocks and fixed income. Additionally, most companies offer a 401k match up to a certain percentage. In most cases, you must participate to receive your employer match.

There are three types of 401k contributions – traditional 401k tax-deferred, tax-exempt Roth 401k, and After-tax contributions.

You can select to make both types of tax-deferred and Roth contributions simultaneously. However,  the combined annual contribution amount cannot exceed your annual limit.

Tax-deferred 401k

Most employees commonly choose to make tax-deferred 401k contributions. These payments are tax-deductible. They will lower your tax bill for the current tax year. Your investments will grow on a tax-deferred basis. Therefore, you will only owe federal and state taxes when you start withdrawing your savings.

Roth 401k

Roth 401k contributions are pretax. You will pay all federal and state taxes before making your contributions. The advantage of Roth 401k is that your retirement savings will grow tax-free. If you keep your money until retirement, you will withdraw your gain tax-free. It’s a great alternative for young professionals and workers in a low tax bracket.

After-Tax 401k Contributions

Some 401k plans will allow you to make after-tax contributions. You can make these contributions if you have maximized your annual limit. Generally, after-tax contributions are made after you pay taxes on your income. Only your future gains will be taxable as ordinary income. Due to these tax complexities, after-tax contributions are more common as part of a Mega Backdoor Roth conversion.

Mega Backdoor Roth conversion

Mega back door conversion is a two-step process that allows you to make after-tax contributions to your 401k plan and immediately transfer the money to your Roth 401k account through in-service conversion.
