401(k) Rollover After Retirement: What to Check Before You Move the Money

Rolling a 401(k) into an IRA after retirement feels like a paperwork task, but it is really a tax and planning decision with a few traps hiding in the fine print.

The instinct is usually to consolidate: one account, one statement, no more old employer portal. That is often a good reason to roll over, but it is not automatically the right move for everyone. Fees, investment choices, creditor protection, RMD timing, and employer stock all change depending on whether you leave the money in the 401(k) or move it.

This article is educational, not individualized financial, tax, investment, insurance, or legal advice. Use it as a planning framework, then review personal decisions with qualified professionals.

The rollover itself should be direct, not a check to you

A direct rollover moves money from the 401(k) to an IRA without the money passing through your hands, and without withholding. An indirect rollover sends you a check with 20% withheld for taxes, and you have 60 days to complete the transfer. Miss that window and the whole amount can become taxable income, plus a possible penalty if you are under 59½.

The 20% withholding is the quiet trap. If you receive a check for $100,000, only $80,000 actually reaches you. To complete a full indirect rollover you have to replace that $20,000 from other cash, then wait to get it back at tax time. A direct rollover avoids the whole problem, which is why most people should insist on it.

The mechanics matter because they are where money is lost, not saved. Ask the plan administrator for a direct trustee-to-trustee transfer and confirm with the receiving IRA custodian before anything moves.

Fees and investment choice usually favor the IRA, but not always

Many 401(k)s offer a limited menu of funds, some with administrative fees layered on top of fund expenses. An IRA opens up a wider range of investments and can lower costs. That is the strongest argument for rolling over.

The exception is a large employer with a great plan. Some 401(k)s offer institutional share classes and stable value funds that are not available in an IRA. A stable value fund, in particular, can behave like a high-yield cash option that an IRA cannot easily replicate. If the plan is genuinely low-cost and well-run, leaving money there is not a mistake.

Do the comparison with real numbers: the total expense ratio of what you hold in the 401(k) versus what you would hold in the IRA, plus any plan-level administrative fees. A difference of half a percent compounds for decades.

Creditor protection can be better inside the 401(k)

401(k) assets are generally protected from creditors under federal law. IRA protection is governed by state law and can be weaker or capped, and the specifics vary by state. For most retirees this is a background concern, but for someone in a profession with liability risk, or who has reason to worry about creditors, it can be a real factor.

This is not a reason to skip a rollover by default. It is a reason to check your state's rules before you move a large balance out of the stronger federal protection. The decision should be informed, not assumed.

RMDs and the still-working rule change the timing

Once you turn 73 (or the applicable RMD age), both 401(k)s and traditional IRAs require required minimum distributions. The key exception is the still-working rule: if you are still employed at the company sponsoring the 401(k) and do not own a controlling share, RMDs from that plan can often be delayed until you actually retire. IRAs have no such exception.

That rule matters if you retire late or work past the RMD age. Rolling the 401(k) into an IRA would start the RMD clock on that money sooner, potentially increasing taxable income. If you plan to keep working, this single detail can argue for leaving the money in place a while longer.

RMDs also cannot be aggregated across different account types the same way. Multiple 401(k)s each require their own RMD, while multiple traditional IRAs can be aggregated for calculation. Consolidating IRAs can simplify the math, but it is a separate question from whether the 401(k) should move in the first place.

RetireFree's RMD Planner can show when distributions begin and how large they get under different rollover and retirement timing assumptions.

Employer stock and the NUA decision

If your 401(k) holds employer stock, rolling it into an IRA forfeits a possible tax break called net unrealized appreciation, or NUA. NUA lets you, in the right circumstances, take employer stock out of the plan and pay ordinary income tax only on the original cost basis, with the appreciation later taxed at long-term capital gains rates when you sell.

That can be a meaningful difference for someone with a large, low-basis position in company stock. But NUA is not automatically better; it depends on the size of the gain, your tax bracket, and how long you plan to hold. Once the stock is rolled into an IRA, the NUA option is gone, so this is a decision to make before the rollover, not after.

This is a case where a specialist is worth the cost. The rules are technical, and a wrong guess is expensive and irreversible.

A rollover is one step in a larger plan. What you do with the money next, and where you live when you do it, both matter.

Bottom line

The right rollover decision is not automatic. Compare fees and investments, check your state's creditor rules, respect the still-working RMD exception, and resolve any employer-stock NUA question before the money moves. Once the transfer is done, some of those choices cannot be undone.

Frequently asked questions

Is it better to leave my 401(k) or roll it into an IRA?

It depends on the plan's fees and investment options, your state's IRA creditor protections, whether the still-working RMD exception applies, and whether you hold employer stock with NUA potential. Many people benefit from a rollover, but the answer is specific to your situation.

How long do I have to roll over a 401(k) after leaving a job?

There is generally no deadline to roll over a balance above the plan's cash-out threshold. If you take an indirect rollover, you have 60 days to complete it, and 20% is withheld upfront for taxes. A direct rollover avoids both problems.

Will rolling over a 401(k) trigger taxes or penalties?

A direct rollover to a traditional IRA is generally not a taxable event. Rolling traditional 401(k) money into a Roth IRA is a conversion and is taxable in that year. Rolling after-tax amounts requires care to avoid an unintended tax bill.
