Yes, you can add money to a rollover IRA. The IRS treats it as a traditional IRA, so once your 401(k) or 403(b) balance lands there, you can keep making annual contributions up to $7,500 for 2026, or $8,600 if you are 50 or older.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Before you deposit anything, though, check the eligibility rules, understand how mixing new contributions with rolled-over money affects your options later, and figure out whether the contribution will be deductible.
Who Is Eligible to Contribute
You need taxable compensation during the year you contribute. Wages, salaries, tips, bonuses, self-employment income, and professional fees all qualify. Dividends, interest, rental income, and Social Security benefits do not.2Internal Revenue Service. Publication 590-A (2025), Contributions to Individual Retirement Arrangements (IRAs)
Age is no longer a barrier. Before 2020, contributions to a traditional IRA had to stop at age 70½. The SECURE Act amended 26 U.S.C. § 219(d)(1) to repeal that cap, so anyone with earned income can now contribute at any age.3Office of the Law Revision Counsel. 26 USC 219 – Retirement Savings You can add money to a rollover IRA even while taking required minimum distributions, as long as you have qualifying compensation that year.
If you file jointly and your spouse has taxable compensation, you can contribute to your own rollover IRA even without any earned income of your own. Each spouse can contribute up to the full annual limit, provided the couple’s combined contributions do not exceed the taxable compensation on the joint return.4Internal Revenue Service.

How Much You Can Add in 2026
The 2026 limits are $7,500 if you are under 50, or $8,600 if you are 50 or older (the standard $7,500 plus a $1,100 catch-up).1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
The cap applies across all of your traditional and Roth IRAs combined, not per account. Put $3,000 in a Roth this year, and no more than $4,500 can go into your rollover IRA if you are under 50. The original rolled-over balance from your employer plan does not count against these annual limits.4Internal Revenue Service. Retirement Topics – IRA Contribution Limits
If you contribute too much, the excess is taxed at 6% each year it sits in the account.2Internal Revenue Service. Publication 590-A (2025), Contributions to Individual Retirement Arrangements (IRAs) You can avoid the penalty by withdrawing the excess amount plus any earnings on it by your tax return due date, including extensions.4Internal Revenue Service. Retirement Topics – IRA Contribution Limits Miss that deadline and you can still absorb the overage by contributing less in a future year, but the 6% tax applies each year until it clears.
Whether the Contribution Is Deductible
Eligibility to contribute is one question. Whether you get a tax deduction is another. Two factors decide it: whether you or your spouse is covered by a workplace retirement plan, and your modified adjusted gross income. If neither of you is covered by a workplace plan, the contribution is fully deductible at any income.
When a workplace plan is in the picture, the deduction phases out over these 2026 ranges:1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
- Single filer covered by a workplace plan: $81,000 to $91,000
- Married filing jointly, contributing spouse covered: $129,000 to $149,000
- Married filing jointly, contributor not covered but spouse is: $242,000 to $252,000
- Married filing separately, covered by a workplace plan: $0 to $10,000
Above the top of your range, no portion of the contribution is deductible. You can still put the money in — it becomes a nondeductible, after-tax contribution. Keep good records of any nondeductible amounts, since that portion will not be taxed again when you withdraw it in retirement.
What Mixing Rollover and Contributed Money Costs You
Adding personal contributions to a rollover IRA creates a commingled account holding both employer-plan money and your own deposits. Nothing about that is illegal, but it narrows two options.
Rolling Back Into an Employer Plan
Some 401(k) and 403(b) plans accept incoming rollovers only from IRAs that hold nothing but employer-plan money. If yours has been mixed with regular contributions, a future employer’s plan may reject the transfer. Each plan document controls what it accepts, so the rule varies by employer. If you think you might roll the balance into a future employer plan, keep the rollover money in its own IRA and contribute new money somewhere else.
Bankruptcy Protection
Assets rolled over from a 401(k), 403(b), or 457 plan get unlimited bankruptcy protection under federal law. The dollar cap that applies to ordinary IRA balances does not apply to those rolled-over dollars.5Office of the Law Revision Counsel. 11 U.S. Code 522 – Exemptions Personal contributions to a traditional or Roth IRA are protected only up to an inflation-adjusted ceiling, currently $1,711,975 as of April 2025.6Federal Register. Adjustment of Certain Dollar Amounts Applicable to Bankruptcy Cases Once the two pools are mixed in a single account, proving which dollars came from the employer plan can get difficult. A separate rollover IRA keeps the unlimited protection easy to document.
Making the Deposit Correctly
Contributions for a given tax year can be made anytime from January 1 of that year through the filing deadline the following spring. For the 2026 tax year, the deadline is April 15, 2027.2Internal Revenue Service. Publication 590-A (2025), Contributions to Individual Retirement Arrangements (IRAs) If you deposit between January 1 and April 15, tell your custodian which year the contribution is for. Without instructions, they usually apply it to the current year.
Label it right when you submit the deposit. The custodian’s form or online interface will ask you to classify the money, typically as a regular contribution, a rollover, or a transfer. Pick “regular contribution” (some platforms call it “annual contribution”) so the custodian reports it correctly on Form 5498, which also goes to the IRS.7Internal Revenue Service. Form 5498 IRA Contribution Information 2025 Regular contributions go in Box 1 and rollovers in Box 2; a mislabeled deposit can prompt IRS questions about whether you made an improper rollover.
Most brokerages accept ACH transfers from a linked bank account, mailed checks with a deposit slip that lists your IRA account number and the intended tax year, or wire transfers if you need the money to arrive fast. Deposits generally clear within a few business days. Save the confirmation receipt — the contribution date and amount may matter later.
If Your Income Is Too High to Deduct
Because a rollover IRA follows traditional IRA rules, deductibility depends on the workplace-plan and income tests above. A Roth IRA runs on different mechanics: contributions are never deductible, but qualified retirement withdrawals are tax-free. If your income shuts you out of the traditional deduction, contributing to a Roth instead, or converting some of the rollover balance to a Roth, may be worth a look.
Roth contributions carry their own 2026 income phase-outs: $153,000 to $168,000 for single filers, $242,000 to $252,000 for married couples filing jointly, and $0 to $10,000 for married filing separately.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 If your income exceeds both the Roth limit and the traditional deduction phase-out, you can still put nondeductible contributions into your rollover IRA. Income limits affect the deduction, not the right to contribute.
