Yes, you can withdraw your money at any time. Be aware that with any IRA, there are tax implications for early withdrawals or transfers before you retire. If you can, keep your funds invested for the long term.
From the mobile app or website, navigate to your Acorns Later account and tap the Withdraw button to start the process. You'd need to indicate the reason for withdrawal. We use this reason so that we can categorize your withdrawal and report it back to the IRS.
When you withdraw from your Acorns Later account, you are likely going to receive a 1099-R form from Acorns by the end of January of the following calendar year.
You can learn more about the specifics on the IRS website.
