A lump-sum distribution can also happen:

Taking a lump-sum distribution is usually one of a few choices that you will have. You can also roll the balance of the account over into another retirement plan, take a partial distribution, or keep the benefit in the current account for as long as the plan or account custodian allows. Taking a lump-sum distribution is often not the best choice for an individual, because it can have serious tax consequences. For instance, suppose your 401(k) balance is $100,000, and you have earned 100% vesting (or ownership) of your benefit. Should you decide to “cash it out” and take a check payable to you, the amount you receive will be much less than $100,000 after taxes, but in some cases, it may be the best choice.

How Does a Lump-Sum Distribution Work?

Usually, if you have money in a retirement account, you keep most of the money there to continue earning interest. Then, once you stop working, you take periodic distributions as part of your retirement income. In some cases, though, you may not be able to leave the money in your retirement account. If you have left the employer that’s been funding your 401(k), for example, you may not be allowed to keep your money in the company plan indefinitely. If you do decide to take everything out as a lump sum, there can be significant tax consequences. Your options, in that case, are to take it either in the form of cash (a check payable to you) or in the form of a rollover (a check written to your IRA or another plan custodian on your behalf).

Avoid a Check Payable to You

If you can avoid it, you don’t want to receive your distribution as a direct payout to you. When you do that, the distribution becomes taxable. This new tax status comes into play because your 401(k) contributions, in most cases, were deducted from your paychecks on a pre-tax basis. This means they’ve never been taxed. In most cases, 20% of the cash distribution will be withheld for federal taxes. Out of a $100,000 distribution, that would leave you with an $80,000 check. On top of that, you may be faced with a 10% tax penalty if you withdraw the money before turning 59½. That would leave you with a $70,000 check. You are subject to the 20% tax withholding when you directly receive a cash distribution, even if you intend to roll it over into another retirement plan within 60 days. If you complete the rollover within the time limit, you may use outside funds to restore the withheld amount and defer the payment of the tax.

Roll Over the Funds

The best thing you can do with your 401(k) is to choose the IRA rollover option. This rollover may still be a lump-sum distribution, but instead of receiving a check payable to you, either you will receive a check payable to your IRA custodian, or your custodian will receive the check directly. For example, suppose you open an IRA with Vanguard. When you have stopped working for your employer and you receive your 401(k) distribution options, you will select the option that says something like “Rollover to IRA.” The check will be written to Vanguard (not to you personally). If done correctly, the check will also say “FBO [your name],” which means “for the benefit of [you].” When the rollover check is made payable to Vanguard instead of you, you do not pay taxes or penalties on the distribution. That’s because you were never actually in receipt of the money at any point.

How to Invest a Lump-Sum Distribution

Once your IRA custodian has the rollover check, you will have cash in your IRA that needs to be invested. You have two basic choices: Invest it all at once, or invest it in increments over time. If you want to invest it all at once, you should take care to diversify (spread your risk over several different types of investments). You can do that through a portfolio of mutual funds. If you want to reduce market risk, you can use dollar-cost averaging (DCA) to invest a set amount of money per month into your chosen mutual funds over a certain period, such as a year. That way, if the market fluctuates widely, you will buy some shares at higher prices and some shares at lower prices. That would average out your costs and use your money more effectively. Most investors will find DCA to be more effective than trying to time the market.
