Switching Brokerages: What Happens to Your Investments and Records

Updated September 26, 2026.

When you switch brokerages, eligible investments may move in kind without being sold, while unsupported assets can require separate handling. The receiving firm should confirm the process for your exact account and holdings. A transfer is not the same as selling, withdrawing money or connecting an account to a financial application.

That distinction is the starting point. If your goal is simply to see several accounts together, you may not need a brokerage move. If you want a different custodian, compare the receiving firm's support, costs and service before authorizing the transfer.

Three different actions

Do not assume a request to close an account means the same thing as an in-kind transfer. Ask the institutions to identify the exact action and its consequences.

How the transfer process generally works

Most brokerage account transfers use ACATS, the industry transfer system, while some transfers require a manual process. The receiving firm coordinates an authorized request with the carrying firm. Eligibility depends on the firms, account and assets involved. FINRA customer-account transfers

Start by asking the receiving firm what it needs for the specific registration and transfer type. Names, ownership and account details need to align. A generic article cannot supply the exact forms or guarantee a completion date for every account.

Ask whether a full or partial transfer is supported and how ongoing activity will be handled. Some providers impose product-specific limits. Do not assume a rule described for one robo-advisor or brokerage applies to another.

Review every holding before authorizing the move

Make a list of securities, cash, fractional shares and any investments with unusual restrictions. Ask the receiving institution to identify what it can accept, what requires additional steps and what cannot be transferred as requested.

Fractional shares deserve attention: FINRA notes their limited transferability between firms. Confirm how the existing institution handles them and any resulting cash or tax records. Do not liquidate the whole position merely because a fraction needs separate treatment. FINRA fractional-share guidance

For restricted, proprietary or otherwise unsupported assets, obtain an explicit answer rather than assuming they will disappear into the transfer process. The choice may involve leaving them where they are or another institution-approved solution.

Understand what could happen to taxes

Moving the same holdings between compatible taxable brokerage accounts in kind is different from selling them. A sale, including one involving an unsupported position or fractional interest, can create a gain or loss. Ownership changes and retirement accounts introduce other considerations.

Use the institution's records to inspect basis before any proposed sale. If loss transactions are involved, review relevant household activity rather than assuming a brokerage change removes wash-sale concerns. See the cross-account review guide.

Do not treat this article as a rollover procedure for a retirement plan. For that distinct process, start with the old 401(k) consolidation guide and your plan administrator's current instructions.

Plan around service interruptions

Ask both firms what trading or account activity may be restricted during the transfer. Consider scheduled purchases, distributions, pending trades, bill-related cash needs and other instructions. Obtain provider-specific guidance on what should remain active or change.

Avoid a blanket instruction to turn everything off. A recurring action may serve a purpose, and changing it prematurely can create another problem. Record what each institution tells you and who owns follow-up.

The same applies to closure: confirm whether the transfer closes the old account, whether residual activity may arrive later, and how you will access final documents.

Reconcile assets and records separately

A portfolio appearing at the new institution is not the end of the review. Check holdings, quantities, cash and tax records against what you expected.

If basis is missing or seems incorrect, contact the institutions with the original records. Do not interpret a blank field as zero basis or a completed tax determination. Retain pre-transfer statements and lot records even when the receiving screen looks correct.

Where Mezzi helps—and where it does not

Mezzi can bring supported accounts into a broader financial picture, including investments, banking, liabilities and manual assets. That may help you review the overall allocation before and after a move. Mezzi account groups

It is not the receiving brokerage and does not complete ACATS transfers. A connected view can also lag the institutions or show both old and new records during a transition. Check for duplicate-looking holdings before drawing conclusions from a combined balance.

Use AI Personalization to state the goal behind the change, then ask what information is missing from the review. Verify holdings and basis at the institutions. Review current Mezzi capabilities for the guidance role rather than expecting it to administer the transfer.

A useful completion standard

The move is ready to close out when the institutions have resolved asset handling, relevant records reconcile, residual activity is understood and ongoing responsibilities are assigned. Keep unresolved questions visible rather than treating a changed account balance as proof that every detail is finished.

A good transfer changes the custody arrangement you intended to change while leaving you able to explain what happened to each investment and record.

Frequently asked questions

Do I have to sell investments to switch brokerages?

Not necessarily. Eligible holdings may transfer in kind. Ask the receiving firm which assets it can accept and how unsupported or fractional holdings will be handled.

Does connecting an account to Mezzi transfer it?

No. A supported connection provides information for guidance; it does not move custody or make Mezzi the receiving brokerage.

What if cost basis is missing after a transfer?

Compare retained lot records and statements, then contact the institutions to resolve the discrepancy. Do not assume a blank basis field means zero or use it as a final tax figure.

How long does a transfer take?

Timing depends on the firms, assets, account type and any issues. Obtain an estimate and follow-up process for your exact transfer rather than relying on a universal deadline.
