Betterment for Advisors also supports ACATS of cash positions. For information on this process, please see here.
For non-IRA accounts, for virtually all ETFs (see above link), we now support ACATS transfers in for all ETFs. We will hold these positions in a transitional Betterment account from which you will be able to liquidate all or a portion of the assets to move into a Betterment portfolio. Please keep in mind that individuals tickers cannot be selected for transfer of assets out of the transitional account, only specific dollar amounts.
We are not currently able to support ACATS transfers out of Betterment, but clients can transfer their securities from Betterment in-kind via a direct transfer facilitated through the DTC. We do not support partial in-kind transfers, so clients would need to transfer out ALL taxable assets if they chose to use DTC (including any assets that were already in the Betterment portfolios).
For IRA accounts, we support ACATS transfers for these providers and virtually all ETFs (see above link).
