What are the different types of retirement investment accounts, such as 401(k), IRA, or taxable brokerage accounts?

There are several types of retirement investment accounts that individuals can use to save for retirement. Here are some common ones:

401(k): A 401(k) is an employersponsored retirement savings plan that allows employees to contribute a portion of their pretax income to a retirement account. The contributions grow taxfree until withdrawn in retirement, and some employers offer matching contributions.

Traditional IRA: A traditional IRA is an individual retirement account that allows individuals to contribute pretax income to a retirement account. The contributions and earnings grow taxfree until withdrawn in retirement, and contributions may be taxdeductible.

Roth IRA: A Roth IRA is an individual retirement account that allows individuals to contribute aftertax income to a retirement account. The contributions and earnings grow taxfree and may be withdrawn taxfree in retirement, as long as certain conditions are met.

SEP IRA: A Simplified Employee Pension (SEP) IRA is a retirement account that allows selfemployed individuals and small business owners to contribute to their own retirement account, as well as their employees' retirement accounts.

Solo 401(k): A Solo 401(k) is a retirement savings plan designed for selfemployed individuals and small business owners with no employees, allowing them to make contributions as both the employer and employee.

Taxable brokerage accounts: Taxable brokerage accounts are investment accounts that allow individuals to invest in a variety of assets, such as stocks, bonds, and mutual funds. These accounts do not offer the tax advantages of retirement accounts, but they offer more flexibility in terms of withdrawal restrictions and contribution limits.
