What is a rollover IRA?

Key points

• A rollover IRA usually means a traditional IRA holding money moved from an employer retirement plan. It is not a separate tax category with its own withdrawal rules.
• An eligible pre-tax plan balance can move to a traditional IRA without current income tax. Moving that balance to a Roth IRA instead generally makes it taxable.
• A rollover does not count against the ordinary annual IRA contribution limit. Regular contributions remain subject to their own eligibility, compensation and deduction rules.
• The IRA label does not preserve every plan feature. The rule of 55, employer-stock tax treatment and any plan loan option need separate attention.

An account can be called a rollover IRA on a statement and still be a traditional IRA for federal tax purposes. IRS Publication 590-A describes a traditional IRA used to hold employer-plan rollover money as a conduit IRA. The funding history matters for records, but it does not replace the rules for the receiving account.

For the available routes before choosing the account, see the 401(k) rollover overview.

Is a rollover IRA different from a traditional IRA?

The terms answer different questions. Traditional describes the tax treatment of the account. Rollover describes how money arrived.

Term	What it tells you	What it does not tell you
Traditional IRA	The account follows traditional IRA tax rules	Whether every dollar is pre-tax
Rollover IRA	The account holds money moved from a retirement plan or account	Whether its fees or investments suit a particular reader
Roth IRA	The account follows Roth IRA rules	Whether a pre-tax rollover into it is tax-free
Conduit IRA	A traditional IRA holds rollover assets that may later move to a plan	Whether a future employer plan will accept them

A traditional IRA may contain deductible contributions, rollover money and nondeductible contributions. Nondeductible amounts are basis: money already included in taxable income. A statement’s account name is not a reliable substitute for those tax records.

If the old 401(k) contains a designated Roth account, that money cannot be rolled into a traditional IRA. A Roth IRA is an eligible destination. Pre-tax money and designated Roth money need instructions that match their character.

How do you fund a rollover IRA?

A direct rollover has the old employer plan pay the receiving IRA trustee or custodian. The plan may use an electronic payment or a check payable to that institution for your benefit. A check can be mailed to you for delivery and still be a direct rollover if it is payable correctly.

If the plan instead pays an eligible taxable distribution to you, it generally withholds 20%. You then face the ordinary 60-day rollover period and need other funds to replace the withholding if the entire gross distribution is to be rolled over.

These mechanics are explained in direct versus indirect rollovers. The phrase rollover IRA does not itself select a direct payment. The distribution election does.

The money also needs to be eligible to leave the old plan. Required minimum distributions and hardship distributions are not eligible rollover distributions. Opening an IRA does not change that.

Once the receiving IRA has accepted the payment, check both the rollover record and the investment position. Depositing retirement money and investing it are separate instructions. No tax rule makes an uninvested balance turn automatically into a chosen portfolio.

Does a rollover use the IRA contribution limit?

No. Publication 590-A separates rollover contributions from ordinary annual contributions. A qualifying rollover is not capped by that annual dollar limit and does not consume it.

Regular contributions to a traditional IRA can coexist with rollover assets. Their deductibility is a different question, affected by compensation, income and workplace-plan coverage. There is no new deduction merely for moving previously tax-deferred money into an IRA.

Publication 590-A also states that a conduit IRA can later be rolled into a qualified plan even if regular contributions or other funds have been added. That is not permission to move every dollar indiscriminately: the receiving plan has to accept the rollover, and non-taxable IRA basis cannot be rolled into an employer plan.

Keeping funding records separate can therefore be useful even when the tax law does not demand a separate account for each source. The records explain what was deductible, what was rolled over and what was already taxed.

What taxes apply to a rollover IRA?

An eligible pre-tax plan balance rolled into a traditional IRA generally remains untaxed until distributed. This is tax deferral, not a permanent exclusion.

Later taxable distributions from the traditional IRA are ordinary income. Before 59 and a half, the taxable amount can also face a 10% additional tax unless an IRA exception applies.

A rollover from pre-tax plan money to a Roth IRA instead generally adds the pre-tax amount to income in the rollover year. Using a direct rollover can avoid mandatory withholding while leaving that income tax fully applicable.

A taxable Roth conversion or plan-to-Roth rollover also has its own 5-year early-withdrawal clock. Before age 59 and a half, withdrawing amounts attributable to its taxable portion within that period can trigger the 10% additional tax unless an exception applies. This is separate from the Roth IRA clock for qualified distributions.

What if the IRA contains after-tax basis?

A separate rollover IRA does not isolate its tax treatment from all other traditional IRAs. Form 8606 applies aggregation rules to traditional IRAs, including traditional SEP and SIMPLE IRAs, when calculating the taxable and nontaxable shares of distributions and conversions.

The year-end value of all relevant IRAs enters that calculation. Selecting the account with a particular label does not let the owner declare that only basis, or only a chosen pre-tax deposit, was distributed.

The after-tax basis remains important. It is not automatically taxed twice, but its recovery follows the form’s allocation rather than the owner’s preferred ordering. Keep old Forms 8606 and the plan’s documentation of any after-tax rollover.

Can you move a rollover IRA again?

Yes, if the next transaction and destination qualify. Three common routes have different limits.

Another traditional IRA by trustee transfer. The trustees move the money directly. The IRA one-per-year rollover limit does not apply to that transfer.

Another IRA after payment to you. The ordinary 60-day rule applies. Tax-free traditional-to-traditional or Roth-to-Roth rollovers of this kind are generally limited to one across your IRAs in a 12-month period. Moving money out of a different account does not reset the allowance. Traditional-to-Roth conversions do not use that annual rollover slot.

An employer plan. A qualified plan can accept eligible traditional IRA rollover money if its terms allow it. The plan need not accept rollovers at all. Amounts that would otherwise be tax-free because they represent IRA basis are not eligible for that plan rollover.

The IRA one-rollover-per-year guide covers the timing rule. It does not limit the original plan-to-IRA rollover that created the account.

If the money comes from a SIMPLE IRA, its first-two-years restriction matters before moving it to a non-SIMPLE IRA or employer plan. An account label cannot shorten that period.

Does an IRA necessarily cost less?

No. Compare the actual services and fee schedules, not the names of the accounts. An IRA can include investment expenses, account charges, trading costs and an advisory fee. A plan can charge administration costs in addition to underlying investment expenses.

Hypothetical one-year comparison. Suppose the balance stays at $200,000 for fee-calculation purposes. One arrangement has an all-in annual charge of 0.25%; another has an all-in annual charge of 0.85%. Assume no other fees, no investment return and no deposits or withdrawals.

Assumed annual rate	Calculation	One-year cost
0.25%	$200,000 x 0.0025	$500
0.85%	$200,000 x 0.0085	$1,700
Difference	$1,700 minus $500	$1,200

These are invented rates, not an average for IRAs or employer plans. Either account type could be the lower-cost arrangement. The example isolates a fee difference; it does not project investment returns or value the services provided.

A useful comparison lists what each charge buys and whether it is already included elsewhere. Counting the same fund expense twice would overstate the cost. Ignoring an advisory charge would understate it.

What plan features can be lost?

The rule of 55. If separation from the employer qualifies, distributions from that employer’s plan may escape the additional 10% tax before 59 and a half. That exception does not apply to IRA distributions. A rollover does not transport it into the IRA.

Employer-stock treatment. Certain distributions of employer securities can use net unrealized appreciation rules. Rolling the stock into an IRA can surrender that treatment. The tax review belongs before the stock leaves the plan.

Borrowing. IRAs do not permit participant loans. A workplace plan may offer them under its terms, although that does not mean a former employee can borrow from the old plan.

RMD timing. Traditional IRA RMD rules apply even if the owner continues working. The current employer’s plan may offer a still-working delay when the owner and plan qualify. The RMD calculator helps estimate an IRA’s required withdrawal, not the merits of a rollover.

These differences explain why consolidation is not the same as an improvement. The old-401(k) decision guide compares leaving the plan with moving it.

Which documents establish what happened?

The record trail is more useful than the account nickname.

• The old plan’s distribution statement establishes the amount leaving and its tax components.
• The receiving institution’s confirmation establishes which IRA received it and how it was coded.
• Form 1099-R reports the plan distribution, including direct rollovers.
• Form 5498 reports rollover contributions received by an IRA.
• Basis records and Form 8606 establish already-taxed amounts when applicable.

Compare those records with the transaction intended. A tax-free rollover still generates reporting. Conversely, a form marked as a rollover cannot turn an ineligible distribution into an eligible one.

The step-by-step transfer guide provides a practical sequence for matching the old plan’s instructions with the receiving IRA’s details.
