Understand the differences between the two plans, including how the accounts are taxed.
Key Points
- 401(k) plans offer higher contribution limits and may include employer matching.
- If your company does not offer a 401(k), a Roth IRA is a smart choice because of its flexible withdrawals and tax-free growth.
- You may combine the two accounts to maximise your retirement savings and tax advantages.
Roth IRA vs. 401(k): Which One Is Better for You?
The Roth IRA and the 401(k) are two of the most popular retirement plans. The greatest difference between a Roth IRA and a 401(k) is that anyone with earned income can establish and fund a Roth IRA, whereas a 401(k) is only available through your employer. In this post, we’ll help you analyse the advantages and downsides of each and decide what plan is best for you.
401(k) vs. Roth IRA: Choosing the best plan for you
First off, a 401(k) is a suitable alternative for those with an employer match, modest plan fees, and an expectation that their effective income tax rate in retirement will be lower than their current marginal tax rate. You also can’t exceed the 401(k) contribution limit. Before you decide, make sure to explore your investing alternatives in the 401(k) plan.
If you don’t have access to a 401(k) via your company, a Roth IRA is a terrific option, with low fees and more freedom on investments and withdrawals.
You may contribute to both a 401(k) and a Roth IRA, however. That said, if your 401(k) has excessive fees, at least contribute enough to obtain the full company match. That would more than cover the increased expenses of a 401(k).
And contributing to both will help diversify the tax status of your withdrawals in retirement, as withdrawals from 401(k)s are taxed, while withdrawals from Roth IRAs are not. That provides you more control over your tax rate in retirement, enabling you to minimise how much you pay the government.
Knowing the advantages and disadvantages of each retirement account might help you make the best choice for your future.
Pros and cons of 401(k) plans
With a 401(k) plan, retirement savings are deducted from an employee’s pay cheque and deposited into a 401(k) account.
A 401(k) offers several advantages:
- Employer match: An employer match might instantly add 50 percent or 100 percent to your savings. Various employers have various policies on how much of an employee’s income they’ll match, but it’s free money simply for saving for retirement.
- 401(k)s have high contribution limits: You can invest more in a 401(k) than in any other retirement savings plan.
In 2025, the 401(k) contribution limits are:
- $23,500 for workers younger than 50.
- $31,000 for workers ages 50 to 59 or 64 and older.
- $34,750 for workers ages 60 to 63.
In 2025, total combined limits for employee and employer contributions are:
- $70,000 for workers younger than 50.
- $77,500 for workers ages 50 to 59 or 64 and older.
- $81,250 for workers ages 60 to 63.
In 2026, the 401(k) contribution limits are:
- $24,500 for workers younger than 50.
- $32,5000 for workers ages 50 to 59 or 64 and older.
- $35,750 for workers ages 60 to 63.
In 2026, total combined limits for employee and employer contributions are:
- $72,000 for workers younger than 50.
- $80,000 for workers ages 50 to 59 or 64 and older.
- $83,250 for workers ages 60 to 63.
401(k) Tax savings: If you play your cards right, you may save on taxes with a 401(k). Contributions are not taxable as income in the year they are made. You won’t pay taxes when you sell your assets either. You only pay taxes when you take money from the account, giving you more control over your tax rate.
Loan option: Many 401 (k) plans include a loan option. When you need funds for a significant purchase (like a new house), and interest rates are high, a loan from your 401(k) might be a suitable alternative. You may pay yourself back (with interest) and avoid early withdrawal penalties.
But 401(k) plans often come with a few drawbacks as well:
High fees: 401(k) plans might include a plan administration fee, usually levied as a percentage of assets. And investors might pay quite hefty fees on their investment selections.
Limited investment options: A few 401(k) plans may limit your investment choices to a handful of mutual funds or ETFs. You may request that your plan administrator include the investment options you want, but they may not be part of your plan.
Early withdrawal penalties: You probably can’t access your funds penalty-free before age 59 1/2. There are only a few exceptions to that regulation, such as leaving the military early or taking a loan withdrawal (which you have to pay back). 401(k) accounts are designed to be used as a retirement savings tool; the government doesn’t want you to withdraw money from them early.
Required minimum distributions: Beginning the year you turn 73, you’ll be required to take a certain amount from your regular 401(k) account each year. These are minimal distributions you are obligated to take, and they depend on your account balance and life expectancy, which might throw a kink into your tax strategy. Note, however, that RMDs no longer apply to Roth 401(k)s.
Pros and cons of Roth IRA plans
Here are some of the biggest advantages of a Roth IRA:
Tax-free withdrawals: You pay income taxes on Roth IRA contributions upfront. This means that you won’t pay tax on any capital gains from your assets, and your savings will grow tax-free. Your withdrawals are also not subject to income tax
No early withdrawal penalty on donations. Unlike a 401(k) or other standard pre-tax retirement savings account, you may withdraw contributions to a Roth IRA at any time without penalty. Note that gains on your contributions are not excluded from the penalty for early withdrawals (before age 59).
No mandated minimum distribution: You won’t be forced by the government to remove money from your Roth IRA until you need it. This enables greater tax-free development.
More investment options: The only limitation on your investment choices is what your financial institution offers. You get to select whatever financial institution you start your IRA with, so you should be able to locate one that permits you to invest your Roth IRA assets as you see fit.
Low Fees: Look for a financial institution that doesn’t charge you many, if any, fees on your Roth IRA.<
There are some negatives to a Roth IRA as well:
Income restrictions: If your modified adjusted gross income (MAGI) is over the Roth IRA income limit, you cannot make a direct Roth IRA contribution.
The 2025 Roth IRA income limits for single filers are:
- Less than $150,000: Eligible to make full contributions.
- $150,000 to $165,000: Eligible for reduced contributions.
- Above $165,000: Ineligible to directly contribute.
The 2025Roth IRA income limits for married couples filing jointly are:
- Less than $236,000: Eligible to make full contributions.
- $236,000 to $246,000: Eligible for reduced contributions.
- Above $246,000: Ineligible to directly contribute.
The 2026 Roth IRA income limits for single filers are:
- Less than $153,000: Eligible to make full contributions.
- $153,000 to $168,000: Eligible for reduced contributions.
- Above $168,000: Ineligible to directly contribute.
The 2026 Roth IRA income limits for married couples filing jointly are:
- Less than $242,000: Eligible to make full contributions.
- $242,000 to $252,000: Eligible for reduced contributions.
- Above $252,000: Ineligible to directly contribute.
If your salary is beyond those restrictions, you’ll have to employ the backdoor Roth IRA technique. This is a multi-step process that adds complexity to your retirement planning.
Lower contribution limits: The maximum contribution to a Roth IRA is $7,000 in 2025 and $7,500 in 2026. If you’re age 50 or older in 2025, you may make an additional catch-up contribution of $1,000 and another $1,100 in 2026. That’s not a lot compared to other retirement savings vehicles, like a 401(k).
Pay taxes now: If you are in a high-income tax band now, it may not make sense to pay a high rate of taxes immediately. You may minimise your tax payment by deferring those taxes in another sort of retirement plan, such as a 401(k) or a regular IRA.
