401k 101: A Comprehensive Guide to Retirement Planning

Retirement planning can be overwhelming, but understanding the basics of a 401k can help you get started. A 401k is a type of employer-sponsored retirement plan that allows you to contribute a portion of your paycheck to a tax-deferred investment account.

You can contribute to a 401k through payroll deductions, which can be set up through your HR department. Most employers offer a 401k plan as a benefit to their employees.

The maximum annual contribution limit for a 401k is $19,500 in 2022, with an additional $6,500 catch-up contribution allowed for those 50 and older.

Traditional 401(k) plans offer tax benefits when you contribute the money, reducing your taxable income for the year.

Contributions to a Roth 401(k) are made with after-tax income, which means you've already paid your taxes on that money.

A Third-Party Administrator (TPA) will develop illustrations showing how much you could contribute and the amount you would need to give your team. They will also keep the plan in compliance with the IRS and Department of Labor (DOL) rules and regulations.
