To combine retirement accounts, you move balances from your old accounts into one receiving account of a compatible type, ideally through a direct trustee-to-trustee transfer so no money passes through your hands and no taxes are triggered. Pre-tax money (Traditional IRAs, most 401(k)s, 403(b)s, governmental 457(b)s) merges with other pre-tax accounts. Roth money stays with Roth. Match the types, use a direct transfer, and the consolidation is routine. The tax bills people worry about come almost entirely from breaking one of those two rules.
Which Accounts Can Merge Into Which
The IRS keeps a rollover chart that spells out every allowed combination. The pattern behind it is simple: pre-tax money moves with pre-tax money, and after-tax (Roth) money moves with after-tax money.
- A Traditional 401(k), 403(b), or governmental 457(b) can roll into a Traditional IRA. This is the most common consolidation move after leaving a job.
- Multiple Traditional IRAs can be combined into one. SEP-IRAs can roll into a Traditional IRA or another SEP-IRA.
- Roth IRAs can only be combined with other Roth IRAs.
- A designated Roth 401(k) or Roth 403(b) can roll into a Roth IRA without tax, since both are already after-tax.
- If your current employer’s plan accepts incoming rollovers, an old 401(k) can go directly into the new plan instead of an IRA.
Two moves are not allowed: you cannot roll a Roth IRA into a Traditional IRA, and you cannot roll any IRA into a designated Roth account inside an employer plan.1Internal Revenue Service. Rollover Chart
One boundary worth naming, because people sometimes assume it fits under “combining accounts”: moving pre-tax funds into a Roth IRA is a Roth conversion, not a consolidation. The entire converted amount is added to your taxable income for that year.2Office of the Law Revision Counsel. 26 USC 408A – Roth IRAs If your goal is fewer accounts rather than a change of tax treatment, keep pre-tax with pre-tax.
Use a Direct Transfer, Not a Check to Yourself
There are two ways to move retirement money, and choosing well matters more than any other decision in the process.
A direct rollover (also called a trustee-to-trustee transfer) sends the money from the old custodian straight to the new one. You never touch the funds. The check, if one is issued, is made payable to the new institution for your benefit, or the transfer runs electronically. There is no tax withholding, no 60-day deadline to worry about, and no annual limit on how many you can do.3Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
An indirect rollover puts the money in your hands. The old custodian cuts you a check, and you have 60 days to redeposit the full amount into a qualifying retirement account. Miss the window, and the distribution is treated as taxable income.4Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts If you are under 59½, the IRS adds a 10% early withdrawal penalty on top.5Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts
When the receiving institution’s transfer form asks you to pick direct or indirect, pick direct unless you have a specific reason not to.
What Can Go Wrong With an Indirect Rollover
The 60-day clock is only the first hazard. Two more catch people who thought they were doing a clean rollover.
Mandatory 20% Withholding on Employer Plans
When an employer plan distributes funds directly to you rather than to another custodian, the plan administrator is required to withhold 20% for federal income taxes.6Office of the Law Revision Counsel. 26 USC 3405 – Special Rules for Pensions, Annuities, and Certain Other Deferred Income On a $50,000 401(k), you receive a check for $40,000. To complete a full rollover, you must deposit the entire $50,000 within 60 days, which means covering the missing $10,000 from your own cash. The withheld amount comes back as a refund the following spring, but you need the money now. Direct rollovers do not have this withholding.
The One-Rollover-Per-Year Rule
If you use an indirect rollover between IRAs, you are limited to one such rollover across all your IRAs in any 12-month period. The IRS treats your Traditional, Roth, SEP, and SIMPLE IRAs as a single pool for this count. A second indirect IRA-to-IRA rollover inside 12 months is treated as a taxable distribution and can also trigger a 6% excess contribution penalty on the receiving side.3Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
The rule does not apply to direct trustee-to-trustee transfers, rollovers from an employer plan into an IRA, or Roth conversions.3Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions Using direct transfers throughout your consolidation sidesteps the limit entirely, which is another reason to default to that method.
If You Miss the 60 Days
Under certain circumstances, the IRS allows self-certification of a waiver: qualifying reasons include serious illness, a death in the family, a financial institution’s error, a check that was misplaced and never cashed, a postal error, or severe damage to your home. The rollover must be completed as soon as the reason no longer applies, generally within 30 days.7Internal Revenue Service. Revenue Procedure 2016-47 – Waiver of 60-Day Rollover Requirement Self-certification is not a guarantee; the IRS can still challenge it on audit.
Money That Cannot Come With You
Some balances are not eligible for rollover, and separating them out before initiating a transfer prevents an accidental taxable event.
- Required minimum distributions. If you are at RMD age, that year’s RMD has to be withdrawn first. It cannot be rolled over.
- Hardship distributions from an employer plan.
- Substantially equal periodic payments taken over your life expectancy.
- Amounts distributed because they exceeded contribution limits.3Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
SIMPLE IRAs Have a Two-Year Waiting Period
During the first two years after you begin participating in a SIMPLE IRA plan, you can only move the money into another SIMPLE IRA. Moving SIMPLE IRA funds into a Traditional IRA, 401(k), or any non-SIMPLE account inside that window is a taxable distribution, and the early withdrawal penalty is 25% rather than the usual 10%. Once the two years are up, SIMPLE IRA money can roll into a Traditional IRA, SEP-IRA, 401(k), 403(b), or governmental 457(b) on ordinary terms.8Internal Revenue Service. SIMPLE IRA Withdrawal and Transfer Rules
Inherited Accounts Have Their Own Rules
A surviving spouse can roll an inherited retirement account into their own IRA and treat it as their own from that point forward. A non-spouse beneficiary cannot. Inherited funds have to stay in an inherited IRA titled in the deceased owner’s name for your benefit. You may combine inherited IRAs from the same original owner into one inherited IRA, but you cannot merge inherited accounts from different original owners, and you cannot mix inherited money with your own retirement savings.9Internal Revenue Service. Retirement Topics – Beneficiary
How to Start the Transfer
Once you have identified compatible accounts, the mechanics are straightforward.
Open the Receiving Account
Open the destination account first if you do not already have one, and confirm it is the correct type. A Traditional IRA receives pre-tax funds; a Roth IRA receives Roth funds. Ask the receiving institution to confirm they accept incoming rollovers from the source account type.
Gather the Details Both Sides Will Ask For
From the old account, you need the account number, the custodian’s name, and, for employer plans, the plan name and the employer’s EIN, which appears on a pay stub, W-2, or through the former employer’s HR department. From the new account, you need the account number, the custodian’s legal name, their mailing address for incoming checks, and any internal routing numbers they use.
Submit the Transfer Request
The receiving institution supplies a Transfer Request Form or Rollover Contribution Form authorizing the old custodian to release your funds. On the form, select direct rollover and specify whether you are moving the full balance or a set dollar amount. Some employer plans still require you to call the plan administrator to initiate the transfer instead of submitting a form to the new custodian.
Track It to Completion
Processing typically runs one to three weeks after the paperwork is verified. Watch the old account for a status change showing release of funds, and watch the new account for the incoming deposit. If a paper check is being mailed between custodians, call the receiving institution to confirm it arrived.
What You’ll See at Tax Time
Even a clean rollover produces tax forms. The releasing institution issues a Form 1099-R for the distribution. A direct rollover carries a distribution code showing no tax is owed, but you still have to report the rollover on your federal return. An indirect rollover’s 1099-R shows the gross distribution and any withholding.
The receiving institution files Form 5498 with the IRS reporting the rollover contribution, and you receive a copy, usually by the end of May the following year.10Internal Revenue Service. Instructions for Forms 1099-R and 5498 Keep the two forms together. If the IRS sees a 1099-R with no matching 5498, it may assume you took a taxable withdrawal and send a notice.
Reasons to Pause Before Moving a 401(k) to an IRA
Two situations argue for leaving an employer plan alone even when consolidation looks tidier.
The first is creditor protection. Funds in an ERISA-covered employer plan such as a 401(k) or 403(b) have broad federal protection from creditors, both in and outside bankruptcy, and that protection is essentially unlimited.11U.S. Department of Labor. FAQs About Retirement Plans and ERISA IRAs are federally protected in bankruptcy only up to an inflation-adjusted cap (roughly $1.5 million to $1.7 million for the current adjustment period), though amounts rolled in from an employer plan generally keep their unlimited protection. Outside bankruptcy, IRA creditor protection is set by state law and ranges from unlimited to fairly weak. In a high-lawsuit-risk profession, the employer plan may be the safer home.
The second is employer stock that has grown substantially inside a 401(k). If that stock is distributed directly to a taxable brokerage account as part of a lump-sum distribution, the growth (called net unrealized appreciation) is taxed at long-term capital gains rates when you eventually sell. Roll the stock into an IRA and the entire amount is taxed as ordinary income on withdrawal instead. You can still roll the non-stock portion of the 401(k) into an IRA while taking the stock separately, preserving the capital gains treatment on the appreciation.
