Transferring a brokerage account to M1 allows you to move your investments and (in most cases) cash seamlessly into your M1 account. This article provides step-by-step transfer instructions, describes supported transfer types, and explains how to manage unsupported securities, track your transfer progress, and troubleshoot common issues.
Prepare for your transfer
Match account types: You must have an open M1 account of the same type as your account at the sending brokerage (e.g., Individual to Individual, Joint to Joint, Roth IRA to Roth IRA).
If needed, learn how to open additional accounts.
Review your investments: Only supported securities can be transferred in-kind. Learn more: What securities can be transferred to M1?
Fractional shares: Only full shares transfer; fractional shares must be liquidated at your previous brokerage.
Step-by-step: Initiate an account transfer
Log in to M1.
From the Home tab, select Move Money.
Click Transfer from another brokerage.
Choose your account transfer type
M1 supports three types of brokerage transfers:
1. Full Account Transfer (ACAT)
Moves all eligible securities and cash from your other brokerage to M1.
Your old account may be closed automatically.
Ideal if you want to fully consolidate your brokerage holdings at M1.
2. Partial Account Transfer (ACAT)
Allows you to select specific investments (stocks, ETFs) and/or cash to transfer.
Your old account remains open.
To initiate a partial transfer:
In the transfer setup, select Partial Account Transfer.
Choose the exact securities and/or cash to move to M1.
Ensure the securities you’re moving are supported by M1 (check here).
Complete the information requested about your external account.
Review and submit your request.
Note: Unsupported assets or fractional shares cannot be transferred and will remain at your old brokerage.
3. Rollover (Non-ACAT)
For qualified retirement accounts only (i.e., transferring funds/assets from a 401(k), 403(b), or 457(b) to an M1 IRA).
This process usually requires contacting your prior provider and requesting a direct rollover (“trustee-to-trustee transfer”) to M1.
Find step-by-step instructions here: How to complete a rollover.
ACAT vs. Non-ACAT transfers
ACAT transfers (Automated Customer Account Transfer Service) are used for most full and partial brokerage-to-brokerage transfers. They are generally faster and more streamlined (4–7 business days).
Non-ACAT transfers are used for assets that can't transfer via ACAT—commonly for certain retirement accounts or directly held securities. These may take longer and often require manual paperwork.
Handling unsupported securities
Unsupported securities (such as mutual funds, bonds, options, international stocks, etc.) cannot be held or traded on M1.
In full account transfers, unsupported assets usually remain at your old brokerage.
In partial transfers, you may only select supported stocks and ETFs.
If an unsupported security does transfer, it will be displayed as a Received Security outside your Pie. You can choose to hold it (if supported), or request liquidation. For details: Received Securities on M1.
How to track your transfer
Log in to M1 via desktop or the latest mobile app.
From your home screen, select All Activity.
Look under Pending Brokerage Transfers to view processing status and details on your transfer.
If your transfer requires additional action (e.g., document upload, clarifications), M1 will notify you via email and your account notifications.
Timeline expectations
ACAT transfers: 4–7 business days (most cases).
Non-ACAT rollovers: 7–14 business days, or longer for certain retirement accounts/direct holdings.
Residual balances/final sweeps: Additional 7–10 days after securities/cash post to M1.
Fees
M1 does not charge an incoming transfer fee.
Your current (sending) brokerage may charge outgoing transfer or closure fees. Contact them directly for details.
Some special fees (e.g., for directly registered shares) apply; check M1's fee schedule.
Troubleshooting & common issues
Transfer not starting/processing:
Verify the external account number and match the account type exactly.
Confirm that names, contact information, and account titles match at both firms.
Transfer rejected:
Usual causes: unsupported securities, mismatched account information, or restricted assets.
Assets missing after transfer:
Only eligible, supported full shares move. Fractional shares and unsupported securities remain at your old firm.
Some residual cash or securities are “swept” in follow-up transfers within 7–10 business days.
Delay exceeding 10 business days:
There may be a hold, missing documentation, or special handling required. Contact M1 Client Success for assistance.
No cost basis data:
Basis usually arrives within 30 days. If missing after 30 days, request cost basis information from your old brokerage and supply it to M1.
