After-Tax Retirement Contributions and ROBS

By Dennis Shirshikov · Published July 27, 2026 · Reviewed July 27, 2026

After-tax employee contributions can change where rollover dollars should go. They do not create extra business cash, and they should not move into a ROBS stock purchase until the source, tax character, receiving plan, and custody instructions are verified.

Direct answer

Sometimes, but only after the plan proves the money is eligible, accepted, and properly accounted for. Non-Roth after-tax employee contribution basis may be rolled to a qualified plan only when the rules for nontaxable amounts are met, including direct trustee-to-trustee movement and separate accounting when the receiving plan accepts the source. Earnings on those contributions are pretax. Designated Roth accounts and Roth IRAs follow different destination rules, and a Roth IRA cannot roll into the ROBS plan.[2][4][9]

For a ROBS transaction, the employer-stock purchase boundary is later. The new plan may use only cash that the receiving plan has accepted, posted to the trust, reconciled by tax character, and released after valuation and fiduciary approval. Basis is a tax record that prevents double taxation; it is not a second asset and it is not tax-free corporate money. IRS ROBS guidance supports the stock-purchase sequence, including rollover and direct-transfer records, participant information, stock valuation, and stock purchases.[10][11]

For household planning, coordinate tax-character tracing with whether married spouses can use ROBS together.

Do not send uncertain after-tax, Roth, IRA-basis, rejected, or pending amounts to the corporation. If the receiving plan cannot accept or separately account for the amount, route it to another permitted destination or correct it before any stock purchase.

What after-tax basis means in a ROBS rollover

After-tax basis is the part of a retirement account that has already been taxed to the participant. In an employer plan, that usually means non-Roth employee after-tax contributions. It does not include the investment earnings on those contributions, which IRS guidance treats as pretax money. It also does not turn a retirement-plan rollover into a personal withdrawal or a corporate contribution.[4][5]

Non-Roth employee after-tax contributions

This is the employee contribution basis that has already been taxed inside a qualified plan. It is different from the investment earnings on those contributions. A mixed distribution is treated as containing a proportional share of pretax money and after-tax basis unless Notice 2014-54 allocation rules are used for simultaneous destinations.[3][4][9]

Earnings on after-tax contributions

Earnings tied to after-tax contributions are pretax amounts. If those earnings are distributed, they need their own rollover destination or they become taxable under the usual distribution rules.[4][5]

Designated Roth account

A designated Roth account inside a 401(k), 403(b), or governmental 457(b) is not the same thing as non-Roth after-tax basis. The IRS rollover chart routes designated Roth amounts only to another designated Roth account or a Roth IRA, and nontaxable designated Roth amounts require direct trustee-to-trustee movement.[2][5][9]

Roth IRA or nondeductible IRA basis

A Roth IRA cannot roll into a qualified plan. Nondeductible traditional IRA basis is tracked through Form 8606 and IRA records, not by treating the IRA as a qualified-plan after-tax subaccount. That makes IRA basis a tax-record issue to resolve before a ROBS plan accepts any IRA-sourced amount.[2][7][8]

What must be verified before money moves

The core verification task is to connect the source plan, the tax character, the destination, the movement method, and the later stock purchase before relying on a statement that shows after-tax dollars.

  1. 1. The source plan permits a distribution now, and the amount is an eligible rollover distribution rather than an RMD, hardship distribution, plan-loan offset problem, excess amount, or other excluded amount.
  2. 2. The source records separate pretax balances, employee after-tax contribution basis, earnings on that basis, designated Roth amounts, IRA basis, and any unavailable or restricted amounts.
  3. 3. The receiving qualified plan document accepts the exact source and tax character involved. If non-Roth after-tax basis enters the plan, the plan must separately account for taxable and nontaxable parts and later earnings.
  4. 4. The movement method and payee instructions match the tax character. Where direct trustee-to-trustee transfer is required, checks and wires should be payable to the receiving trustee or custodian for the participant's account, not to the corporation or the individual personally.
  5. 5. If simultaneous destinations are used, written allocation instructions are given before the direct rollovers so pretax and after-tax portions land where intended under Notice 2014-54.
  6. 6. Any rejected, pending, returned, or corrected amount stays outside the stock-purchase amount until the administrator reconciles deposits, earnings, Forms 1099-R/5498, Form 8606 if relevant, and correction instructions.

A receiving plan is not required to accept rollovers, and IRS guidance tells plan administrators to take reasonable steps to determine whether incoming rollover contributions are valid. If an ineligible amount is discovered, the plan may need to distribute it with earnings within a reasonable time to preserve plan qualification.[1][10]

Examples that show the allocation problem

These examples use simplified balances to show the math and the custody question. They do not determine any individual reader's eligibility, tax reporting, or plan-document result.

A split that keeps after-tax basis out of the ROBS stock purchase

$250,000 account = $200,000 pretax + $50,000 after-tax basis. A $100,000 distribution carries $100,000 × $200,000 ÷ $250,000 = $80,000 pretax and $20,000 after-tax basis before destination allocation.

If $80,000 goes by direct rollover to the new qualified plan or a traditional IRA and $20,000 goes at the same time to a Roth IRA with proper allocation instructions, the ROBS plan can rely only on the amount actually accepted by the plan. The Roth IRA dollars never become corporate cash.[3][4]

A receiving plan that accepts pretax money only

A participant asks to move $82,000 out of a $100,000 distribution that contains $80,000 pretax money and $20,000 after-tax basis. If the ROBS plan can accept only pretax money, the plan should not treat any of the after-tax basis as stock-purchase funding.

The workable path may be to move the accepted pretax amount to the qualified plan and send the after-tax basis to a Roth IRA or other permitted destination. If the receiving plan cannot separately account for after-tax basis, the after-tax amount is not released for employer stock.[2][4][10]

A deposit that arrives before its character is resolved

$120,000 arrives at the trust. Source records later show $90,000 pretax, $25,000 after-tax contribution basis, and $5,000 pretax earnings on the after-tax subaccount.

Until the plan administrator verifies acceptance, separate accounting, Form 1099-R expectations, and any return or correction with earnings, the conservative stock-purchase amount is $0. If $25,000 is redirected or returned with $300 of earnings, the file should show the corrected amount and earnings rather than backdating a release.[6][10][11]

Decision guidance before a ROBS plan buys employer stock

After-tax money usually calls for slower rollover instructions and a narrower stock-purchase amount. A clean path may exist when the source plan permits the distribution, the receiving plan accepts the exact character, the basis and earnings are split correctly, and every dollar that will buy employer stock is inside the plan trust as accepted cash.

A ROBS path may be reasonable to evaluate

when most of the usable amount is eligible pretax money, after-tax basis has a permitted destination, the plan administrator can document separate accounting if needed, and the business still has enough capital after any amounts are routed elsewhere.

Alternatives may fit better

when the after-tax portion is large, the receiving plan will not accept it, the participant needs a Roth IRA allocation strategy, or the business purchase depends on counting pending or rejected dollars. In those cases, compare a smaller ROBS rollover, SBA or seller financing, personal cash, or delaying the purchase until the source plan records are clear.

The employer-stock purchase remains a fiduciary transaction. The IRS ROBS project describes rollover assets being used to purchase C corporation stock and highlights stock valuation, rollover or direct-transfer records, and participant information. The corporation receives business cash only after the plan pays for the stock.[11]

Frequently Asked Questions

These answers focus on common source-character problems. Use them to frame the administrator and adviser review before assigning dollars to the stock purchase.

Can after-tax 401(k) contributions be used in a ROBS?

Sometimes. Non-Roth employee after-tax contribution basis can enter the analysis only if the source plan permits an eligible rollover distribution, the receiving qualified plan accepts that tax character, required direct-transfer and separate-accounting rules are met, and the accepted plan-trust cash is released before any employer-stock purchase.[1][2][4][9][11]

Are earnings on after-tax contributions also after-tax?

No. IRS after-tax rollover guidance treats earnings on after-tax contributions as pretax amounts. Keep employee after-tax contribution basis separate from the associated earnings when assigning destinations.[4][5]

How does IRC 402(c)(2) affect a mixed after-tax distribution?

When a distribution contains both taxable and nontaxable amounts, the nontaxable portion generally can roll over only under the statutory limits for direct trustee-to-trustee movement to a separately accounting plan or an IRA. That is why basis, earnings, transfer method, and receiving-plan accounting have to be verified together.[2][4][9]

What does Notice 2014-54 change?

Notice 2014-54 allows simultaneous disbursements to multiple destinations to be treated as a single distribution for allocation purposes. In practice, this can let pretax money go to a traditional IRA or qualified plan while after-tax basis goes to a Roth IRA, if the written instructions and receiving destinations are correct.[3][4]

Can a Roth IRA be rolled into the ROBS plan?

No. The IRS rollover chart shows a Roth IRA cannot roll into a qualified plan. Roth IRA records and Form 8606 reporting are separate from qualified-plan after-tax employee contribution basis.[2][7][8]

What if the receiving plan rejects the after-tax amount after deposit?

Do not use the rejected or uncertain amount for the employer-stock purchase. The plan administrator should reconcile the deposit, tax character, forms, and earnings, then return, redirect, or correct the ineligible amount within a reasonable time when required.[6][10][11]

Bottom line

After-tax employee contributions can enter the ROBS analysis only after source eligibility, proportional allocation, Notice 2014-54 destination instructions, receiving-plan acceptance, separate accounting, custody instructions, and correction handling are clear. If any of those pieces is unresolved, exclude the amount from the employer-stock purchase until the plan administrator and tax or ERISA advisers reconcile it.
