The cleanest way to follow the IRA consolidation rules is to use a direct trustee-to-trustee transfer between accounts that share the same tax treatment. The money moves from one custodian to the other without passing through your hands, the IRS doesn’t treat it as a distribution, and you can run as many transfers as you want in a year.1Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions The work on your end is matching account types correctly, clearing a few traps before you move funds, and verifying afterward that the transaction was coded as a transfer rather than a distribution.
Direct Transfer or Indirect Rollover
A direct trustee-to-trustee transfer is the default to use. Your new custodian contacts your old custodian, the funds move between institutions, and nothing is withheld or reported as a distribution. The one-rollover-per-year rule does not apply to direct transfers, so you can consolidate four or five IRAs in a single pass.1Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
An indirect rollover is the riskier version. The old custodian sends the funds to you, usually by check, and you have 60 days from the date you receive the distribution to deposit the full amount into the new IRA.1Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions Miss the window and the whole amount becomes taxable income. If you are under 59½, add a 10% early withdrawal penalty on top.2Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
A note on withholding: the 20% mandatory federal withholding people associate with retirement distributions applies to 401(k)s and other employer plans, not to IRAs. The default IRA withholding on an indirect rollover is 10%, and you can elect zero. Even so, if 10% is withheld, you still need to deposit the full original amount within 60 days to keep the rollover intact; you cover the withheld piece out of pocket and recover it through your tax return.
The one-rollover-per-year limit is the other reason to avoid indirect rollovers for consolidation. You can complete only one indirect IRA-to-IRA rollover within any 12-month period, and the cap applies across all of your IRAs combined, not per account.1Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions Four Traditional IRAs cannot become one through four indirect rollovers in sequence. Direct transfers have no such limit.
Which Accounts Can Be Combined
You can only combine IRAs that share the same tax treatment. The IRS draws a firm line between pre-tax and after-tax accounts.
Traditional, SEP, and SIMPLE IRAs all hold pre-tax money. Any combination of them can be consolidated into a single Traditional IRA without creating a taxable event, provided any SIMPLE IRA has cleared its two-year waiting period. The assets keep their tax-deferred status, and ordinary income tax applies when you take withdrawals in retirement.
Roth IRAs hold after-tax money. Multiple Roth IRAs can be merged into one Roth IRA with no tax consequences. Roth funds cannot be moved into a Traditional IRA; the tax code has no mechanism for it.
Going the other direction is allowed but is not consolidation. Moving Traditional IRA money into a Roth IRA is a Roth conversion, and the converted amount is added to your taxable income for that year. Convert $50,000 of fully pre-tax Traditional IRA money and you owe income tax on $50,000 at your marginal rate. Partial conversions spread the tax across years. Since 2018, you cannot undo a conversion by recharacterizing it back.
Accounts You Cannot Fold In
Inherited IRAs from someone other than your spouse have to stay in a separate inherited IRA titled in the deceased owner’s name for your benefit. Merging one with your own IRAs is treated as a full distribution of the inherited account, taxable in that year. Inherited IRAs can be combined only with other inherited IRAs from the same deceased person; accounts inherited from different people stay separate because each carries its own distribution schedule.
Surviving spouses have more room. As the sole beneficiary of a deceased spouse’s IRA, you can roll those assets into your own IRA and treat them as your own, after which the normal consolidation rules apply.3Internal Revenue Service. Retirement Topics – Beneficiary Keeping it as an inherited IRA remains an option, which can help if you are under 59½ and want access without the 10% penalty.
SIMPLE IRAs come with their own waiting period. For the first two years after your first contribution to the plan, the only place SIMPLE funds can be transferred or rolled over is another SIMPLE IRA. Moving the money anywhere else during that period triggers a 25% additional tax on the amount withdrawn, more than double the standard early distribution penalty. The two-year clock runs from your first contribution, not the date you opened the account or left the employer, and the restriction applies to direct transfers and Roth conversions as well as indirect rollovers. Once two years have passed, the SIMPLE IRA can move into a Traditional IRA through a direct transfer with no penalty.4Internal Revenue Service. SIMPLE IRA Withdrawal and Transfer Rules
The Pro-Rata Rule If You Have Non-Deductible Basis
If any of your Traditional IRAs contain non-deductible contributions — money you put in with after-tax dollars because you exceeded the income limit for a deduction — the picture gets more complicated. Those after-tax dollars are your basis, and the IRS will not let you selectively convert or withdraw just the basis while leaving the pre-tax money behind.
The pro-rata rule forces every distribution or conversion from your Traditional IRAs to carry a proportional mix of pre-tax and after-tax money. The non-taxable percentage is your total non-deductible contributions divided by the total balance of all your non-Roth IRAs combined.5Internal Revenue Service. About Form 8606, Nondeductible IRAs
The calculation sweeps in every Traditional, SEP, and SIMPLE IRA you own, even across different custodians. Consolidating them into one account changes nothing about the math; the IRS was already treating them as a single pool. With $180,000 of pre-tax IRA money and $20,000 of non-deductible basis, only 10% of any conversion is tax-free, regardless of which account the money sits in.
This matters most for the backdoor Roth strategy, where a high earner makes a non-deductible Traditional IRA contribution and then quickly converts it to a Roth. With no other Traditional IRA balances, the conversion is nearly tax-free. With a large pre-tax IRA sitting on the side, most of the conversion becomes taxable. The IRS uses December 31 IRA balances for the calculation, so moving money in late in the year still counts.
The usual workaround is rolling your pre-tax IRA money into a current employer’s 401(k), if the plan accepts incoming rollovers. Employer plan balances are not included in the pro-rata calculation, so pulling the pre-tax money out of the IRA universe leaves only the non-deductible basis behind. Track your basis on Form 8606, which you file for any year you make non-deductible contributions or take distributions from a Traditional IRA that has basis.6Internal Revenue Service.

Take Any RMD Before You Transfer
If you are 73 or older, or you hold an inherited IRA with annual distribution requirements, take the current year’s required minimum distribution before transferring the account balance. RMD amounts cannot be rolled over.7Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs Transferring the full balance without first satisfying the RMD can leave the undistributed amount tangled in the new account’s reporting, with an excise tax of up to 25% of the missed RMD.
For Traditional IRAs you own (not inherited ones), you do not have to pull the RMD from each account separately. Calculate the combined RMD across all your Traditional IRAs, take the full amount from any one of them, and then transfer the remaining balances.8Internal Revenue Service. Publication 590-B – Distributions from Individual Retirement Arrangements (IRAs) Just make sure the RMD is out the door before you initiate transfers for the year.
How to Run the Transfer
Start with the receiving custodian, the institution where the consolidated IRA will live. Open the new IRA, or designate an existing one, and get the account number. The receiving custodian provides a transfer request form, sometimes called a Letter of Acceptance. Fill it out with the account numbers and contact information for each sending custodian, and make sure the form specifies a direct trustee-to-trustee transfer.
Before you submit the paperwork, decide whether to move the assets in kind or as cash. An in-kind transfer moves your actual holdings — stocks, bonds, mutual funds — without selling them, which avoids trading costs and keeps you invested while the transfer is in motion. Not every receiving custodian can hold every type of investment, though. Proprietary mutual funds from one brokerage often cannot transfer in kind to a competitor, in which case the sending custodian liquidates the position to cash before transferring. That can trigger short-term trading fees on certain fund shares. Ask the receiving custodian what they can accept before you initiate anything.
Some custodians require a Medallion Signature Guarantee on the transfer paperwork, particularly for large balances or securities. This is not the same as a notary stamp; it is a specific authentication of your identity and authority to move the assets. Your bank or brokerage can usually provide one, but you have to appear in person. Check with both custodians early so this does not stall the process.
Transfers typically take two to four weeks. Complex cases or an uncooperative sending custodian can stretch that to six. Once the funds arrive, pull the final statements from both the old and new custodians. Confirm that the full balance moved and that the transaction was coded as a non-reportable direct transfer rather than a distribution. Keep the transfer request forms and final statements indefinitely; they are your proof that no taxable event occurred.
Fixing a Missed 60-Day Deadline
If you took an indirect rollover and missed the 60-day deposit window, the IRS self-certification process may save it. Revenue Procedure 2020-46 lets you certify in writing to the receiving custodian that you missed the deadline for a qualifying reason, and the custodian can accept the late rollover contribution.9Internal Revenue Service. Accepting Late Rollover Contributions Qualifying reasons include:
- Financial institution error by the distributing or receiving custodian
- A distribution check that was lost and never cashed
- Funds deposited into an account you mistakenly believed was an eligible retirement plan
- Severe personal hardship, including serious illness, a death in the family, or significant damage to your home
- Postal error or incarceration
- The distributing institution failing to provide information the receiving custodian needed, despite your reasonable efforts
You use the model letter from the revenue procedure. The receiving custodian can accept the late contribution as long as it has no actual knowledge contradicting your certification.9Internal Revenue Service. Accepting Late Rollover Contributions Self-certification only waives the 60-day requirement; it does not override any other rollover rule, including the one-per-year limit. If your situation does not fit any listed reason, you can request a private letter ruling from the IRS, but the user fee runs over $10,000 and the process takes months.
