Rollover your funds
You can rollover your distributed funds to an IRA, Roth IRA, or another qualified plan after you leave Microsoft. In this case, the issued distribution check will be payable to the new account custodian. Rolling over your vested account balance to another plan can allow you to continue deferral of taxes.
Note: If you decide to rollover your funds to an IRA or Roth IRA, consider opening a new account instead of using an existing account. If no other money is deposited into this new account, the funds can be rolled over to another qualified plan in the future.
Take a cash payout
Upon ending your employment with Microsoft, you can take a 401(k) distribution as a lump sum cash payout, payable to you. Keep in mind that if you choose to cash out your 401(k), you will be subject to taxation. In addition, if you are not yet age 59 ½, you may also be required to pay a 10% penalty. It’s always a good idea to consult your tax and/or financial advisor before choosing to cash out your 401(k) account.
Receiving Microsoft stock in-kind
If you hold shares of Microsoft Common Stock within the 401(k) Plan, you have the option to receive that stock in-kind upon distribution. If you receive your MSFT shares in-kind, you may have the option of not paying tax on the "net unrealized appreciation" of the stock until you sell the stock. Net unrealized appreciation generally is the increase in the value of the employer stock while it was held by the Plan. Treatment of net unrealized appreciation applies only when you receive a total distribution of your entire account or to Microsoft Stock purchased with after-tax contributions.
