Saving up for retirement is important if you want to have financial freedom in your later years. That’s why it’s good to find an investment plan that works for you. However, you may be wondering if you can have a Roth IRA and a 401k. The simple answer is yes.
While you can have a Roth IRA and a 401k, you need to understand the differences between the two. You will need to consider the contribution limits and other factors before you decide if you need both.
Both retirement accounts have their pros and cons when it comes to making the most of your retirement savings. When contemplating if you should contribute to a 401k and a Roth IRA, you need to understand what they are.
What Is a Roth IRA?
A Roth IRA is an individual retirement account set up by you at an investment firm. You have full control over how you want to invest your money. Your choices aren’t as limited as they may be with a 401k. This type of investment account has nothing to do with your employer, so you don’t have to worry about limitations on that end.
Roth IRAs accept funds after tax for your contributions. This means you can make withdrawals tax-free in your retirement. However, you must follow all the applicable rules for avoiding penalties.
What Is a 401k?
A 401k is a retirement plan sponsored by employers. They contribute to your 401k retirement savings by designating a part of your paycheck to it. This means that your contributions are pre-tax. There are many investment options for a 401k, but they may be more limited because of your plan administrator.
You might find a 401k retirement savings plan is most advantageous to you if your employer matches your contribution. This means that your employer contributes additional money to your account. Usually, this is a percentage of your contribution, but no more than a predetermined percentage of your salary.
What are the Differences between a Roth IRA and a 401k?
For retirement, you should take advantage of a 401k and a Roth IRA. You should understand the differences before you contribute to a Roth IRA and 401k plan.
Contribution Limits
A 401k retirement plan has much larger contribution limits than a Roth IRA. These annual contribution limits change every year and vary based on marital status, earned income, and other factors. For a Roth IRA, your ability to contribute depends on your income.
Eligibility
Eligibility differs for these two types of retirement plans. Anyone who has earned income can contribute to a Roth IRA. Unearned income from rental properties, securities or Social Security retirement benefits don’t count. On the other hand, a 401k is only for employees, because it is an employer-sponsored retirement savings plan.
If you can’t directly have a Roth IRA because of income limits, you can contribute to an IRA and 401k. Then, conduct a backdoor Roth conversion to enjoy the tax-free growth.
Tax Treatment
The tax benefits of a Roth and a 401k are different. You make Roth IRA contributions with after-tax dollars. However, this also means that you don’t pay taxes when you make withdrawals, so you have tax-free growth.
That’s unlike a 401k plan, which has pre-tax funds. Since a 401k reduces your taxable income, it can actually save you money.
Investment Options
A Roth IRA and a 401k offer different levels of control over your investment options. Investment options vary based on what your plan administrator for your 401k selects. Generally, they tend to be more limited than a Roth IRA. Also, a Roth IRA is an individual plan. It lets you have complete control of your investment choices and options.
Withdrawal Limitations
A 401k plan offers tax-deductible contributions, but you will have to pay taxes on withdrawals. This is not the case for a Roth IRA, as you can avoid taxes and penalties through certain conditions. Examples include:
- Having an account over 5 years old
- Making a withdrawal after you are 59 ½ years old, as the IRS explains
- Using a withdrawal to buy or build your first home (if it is $10,000 or less)
Required Minimum Distributions (RMDs)
Roth IRAs have no RMDs. If you don’t need your money during retirement, then you can leave it for your beneficiaries. This can be a good option for those that want to plan and leave something behind for family members.
A 401k does have RMDs. If you don’t take them, you may face penalties.

Can You Have Both a Roth 401k and a Roth IRA?
Yes, you can have both a Roth 401k and a Roth IRA at the same time. Contributing to one does not prevent you from contributing to the other. Regarding retirement savings, having both a Roth 401k and a Roth IRA can be a smart move.
When you contribute to a 401k and IRA, you make tax-deferred contributions. Roth accounts allow you to contribute after-tax dollars and enjoy tax-free growth. However, it's important to note that each account has its own set of rules and contribution limits.
Should I Do a Roth 401k If I Already Have a Roth IRA?
A Roth 401k is another type of employee-sponsored plan. It combines the benefits of a traditional 401k account with a Roth IRA. Deciding whether to contribute to a Roth IRA and a Roth 401k requires careful consideration. You should consider these factors to make an informed decision:
- financial situation
- retirement goals
- current tax bracket
- expected tax bracket in retirement
- benefits each account offers.
If you're a high earner and looking to stash away money for retirement each year, a Roth 401k could be your best bet. Why? Simply because it doesn't impose any income limits. Plus, if you're keen on making hefty contributions, the Roth 401k allows you to contribute more compared to a Roth IRA.
Do you want more control over your money? With a wider range of investment choices, a Roth IRA could be right up your alley. This is particularly true if you're thinking about leaving the account to an heir in the future.
Can I Max out 401k and Roth IRA in Same Year?
Yes, you can contribute to a 401k and IRA up to their limits because they are separate retirement accounts. It is generally a great idea to max out employer-sponsored retirement accounts. You want to take full advantage of employer contributions. Having a Roth IRA on top of that gives you another financial safety net with tax-free withdrawals.
You should also be mindful of how much you contribute to your Roth IRA. Roth IRA overcontributions are real and they have a penalty. If you make an overcontribution, you can avoid the penalty. You must withdraw the amount before you file your taxes for the year you made the contribution.
You will also need to withdraw any growth that was made with the overcontribution. Remember to add your investment gains to your annual gross income for taxation. Also, if you're younger than 59½ years old, you will pay a 10% early withdrawal penalty on that sum.
Can I Max out 401k and IRA in Same Year?
Yes, it’s possible to max out contributions to your 401k and IRA in the same year. However, keep in mind that you might not be able to claim a tax deduction on all contributions. The IRS allows individuals 50 and older to make extra "catch-up" contributions to each account. If your company also makes matching contributions to your 401k, you’ll have more retirement savings.
Can You Have a 401k, Roth IRA, and Traditional IRA?
Yes, you can have all three types of retirements accounts. However, there may be limited tax benefits based on income and employer plan participation. If you have a 401k, you may have reduced ability to deduct traditional IRA contributions.
Roth IRA contributions also phase out at higher incomes, so you need to pay attention to that. To overcome this, you can option for a Roth conversion.
Start Preparing for Retirement
You can have both a Roth IRA and a 401k account can be beneficial to your retirement savings plan. However, you need expert advice to decide on whether you can or should contribute to both. Each investment option has its tax benefits. Are you still wondering if you can contribute to a Roth IRA and a 401k?
