4 mins readLast updated May 31, 2024by Kate Morgan

In this article, we’ll go over everything you need to know to make a well-informed decision between a Roth IRA/traditional IRA vs a 401(k)/Roth 401(k).


  • A 401(k) is one of the most common ways to save for retirement.

  • Anyone with income can open an IRA through a bank/online brokerage/personal broker/investment company and pay into it, saving and investing in the long term.  

  • Both traditional and Roth 401(k)s and IRAs have their advantages and drawbacks.

  • A financial advisor can help take some of the stress and pressure of planning for retirement.

What is a 401(k) and Roth 401(k)?

Many American employers offer a 401(k) retirement savings plan. It’s named after a section of the U.S. Internal Revenue Code (IRC).

When a person has a 401(k), they have a company-sponsored retirement account. Their employer matches the contributions they make to this account. 

There are two basic types of 401(k) – traditional 401(k)s and Roth 401(k)s.

A traditional 401(k) is an account into which employee contributions are made pre-tax. This reduces the final amount of taxable income an employee earns each year, but withdrawals from the 401(k) are then taxed.

A Roth 401(k) is the opposite. Employee contributions are made after tax, and withdrawals are tax-free (because the tax has already been paid). 

401(k) owners and their employers contribute differently/at different times depending on whether it’s a traditional or Roth account.

Either way, a 401(k) is one of the most common ways to save for retirement – though only 41% of workers in the country currently contribute to a 401(k), even though 68% of workers have access to employer-sponsored plans. 

When you have a 401(k), you are responsible for choosing your specific investments from an assortment of stocks, bonds, mutual funds and target-date funds. There will also be contribution limits (which are impacted by inflation) to consider. 

For 2022, the annual limit on employee contributions for workers under 50 was $20,500, and employee-employer contributions couldn’t total more than $61,000.

Those over 50 could make a $6,500 catch-up contribution, with the limit of employee-employer contributions rising to $67,500. 

It’s wise to speak to a financial advisor when making big financial decisions. Unbiased can help match you with a financial advisor suited to your needs. Simply answer a few questions, and we’ll do the rest. Get started here.

What is an IRA and Roth IRA?

Is an IRA a 401(k)? No. An IRA is an acronym that stands for Individual Retirement Account.

Anyone with income can open an IRA through a bank/online brokerage/personal broker/investment company and pay into it, saving and investing in the long term.  

Unlike a 401(k), there’s no need to involve (or have) an employer when opening an IRA.

There are annual income limitations for deducted contributions, and money held in an IRA usually can’t be withdrawn before the age of 59½ without incurring a 10% tax penalty.

There are four main types of IRA: 

  • A traditional IRA – Like a traditional 401(k), contributions are pre-tax, and withdrawals are taxed. 

  • A Roth IRA – Like a Roth 401(k), contributions are taxed, but qualified distributions are tax-free. 

  • A Simplified Employee Pension (SEP) IRA – Designed for self-employed individuals. 

  • A Savings Incentive Match Plan for Employees (SIMPLE) IRA – Designed for self-employed individuals and small business owners. 

What about rolling over your 401(k) to a Roth IRA? To avoid 401(k) contribution limits, many people at some point choose to change their 401(k) into a Roth IRA.

This is called a Roth conversion, and it allows people to enjoy 401(k) benefits followed by Roth IRA benefits – the best of both worlds.  

It’s important to note that after a Roth conversion, you will owe tax on the money from your 401(k) if it was previously untaxed (but not if you’re transferring from a Roth 401(k) to a Roth IRA).

Plus, though you’ll be able to withdraw contributions, you won’t be able to withdraw earnings (interest and profits) from your Roth IRA for at least five years once you’ve transferred.
