You may be able to contribute to your 401(k) for the previous year if you meet certain requirements. This is known as a prior-year contribution. To qualify, you must have earned compensation in the prior year and have a 401(k) plan available to you. The contribution limit for a prior-year contribution is the lesser of the current year’s limit or the amount you would have been able to contribute in the prior year had you made the contribution. You can make a prior-year contribution up until the tax filing deadline for the prior year, including extensions. Making a prior-year contribution can be a good way to catch up on retirement savings or reduce your current year’s tax bill.
Understanding the Contribution Deadline
The deadline for making traditional and Roth 401(k) contributions is the tax filing deadline, including any extensions. This means that you can make contributions for the previous year up until the tax filing deadline for that year.
For example, the tax filing deadline for 2023 is April 15th, 2024. This means that you can make 401(k) contributions for 2023 up until April 15th, 2024.
- Traditional 401(k) contributions are made pre-tax, meaning they are deducted from your paycheck before taxes are calculated.
- Roth 401(k) contributions are made post-tax, meaning they are not deducted from your paycheck before taxes are calculated.
The contribution limits for 401(k) plans are set by the IRS and vary each year.
| Year | Contribution Limit |
|---|---|
| 2023 | $22,500 |
| 2024 | $23,500 |
Exceptions for Missed Contributions
While the general rule is that 401(k) contributions must be made within the same tax year, there are a few exceptions that allow for missed contributions to be made in the following year.
- Military service: Individuals who are called to active military duty may be able to make catch-up contributions for the missed year(s) after they are discharged.
- Disaster relief: Individuals who are affected by a federally declared disaster may be able to make catch-up contributions for the year in which the disaster occurred.
- Hardship: In rare cases, the IRS may allow individuals to make catch-up contributions for missed years if they can demonstrate a financial hardship that prevented them from making the contributions on time.
| Situation | Catch-up Contribution Allowed |
|---|---|
| Military service | Yes |
| Disaster relief | Yes |
| Hardship | May be |
Retroactive 401(k) Contributions
Under the Taxpayer Relief Act of 1997, taxpayers have the option to make retroactive 401(k) contributions for the prior year. This allows individuals to maximize their retirement savings and potentially reduce their current year’s tax liability.
To qualify for a retroactive 401(k) contribution, the following conditions must be met:
- You must have been eligible to participate in a 401(k) plan for the prior year.
- You must have earned compensation from your employer during the prior year.
- You must make the retroactive contribution within the time limits set by the plan.
- The retroactive contribution must be made on a timely basis.
Retroactive Contributions for Roth IRAs
Roth IRAs also offer the opportunity for retroactive contributions for the prior year. The rules for retroactive contributions to Roth IRAs are similar to those for 401(k) plans. However, there are some key differences:
- Roth IRA contributions are made on an after-tax basis, meaning that they are not deductible from your current year’s income.
- Roth IRA withdrawals are tax-free, as long as certain conditions are met.
- You must meet the income limits to contribute to a Roth IRA.
The following table summarizes the key differences between retroactive 401(k) and Roth IRA contributions:

Making 401k contributions for prior years can have a significant impact on your tax liability. Here’s how it works:
- Reduced taxable income: Contributions to 401k plans are made on a pre-tax basis, meaning they are deducted from your income before taxes are calculated. This reduces your taxable income, which can result in lower income tax liability.
- Tax-deferred growth: Investments in 401k plans grow tax-deferred, meaning you don’t pay taxes on the earnings until you withdraw the funds in retirement. This allows your money to grow faster, potentially reducing your overall tax liability in the long run.
- Taxable withdrawals: When you withdraw funds from your 401k plan, they are taxed as ordinary income. This means you may pay more taxes in retirement if you make large withdrawals and are in a higher tax bracket.
To minimize the tax impact of 401k contributions for prior years, consider the following:
- Contribute as much as possible while you’re in a lower tax bracket.
- Make regular withdrawals to avoid being taxed on a large sum all at once.
- Consider Roth 401k contributions, which are made on a post-tax basis and allow for tax-free withdrawals in retirement.
