ACATS (Automated Customer Account Transfer Service)

ACATS — the Automated Customer Account Transfer Service — is the industry-standard system operated by NSCC for transferring customer accounts between brokerage firms. Most retail brokerage and advisory account transfers move through ACATS. A standard transfer takes 5-7 business ...

How an ACATS transfer works

  1. Receiving firm initiates the transfer based on the client's signed ACAT form.
  2. Delivering firm validates the client signature and account information against its records.
  3. If validated, the delivering firm sends the position list and transfers the assets.
  4. Total transfer time: typically 5-7 business days for clean accounts; longer with reconciliation issues.

What can complicate a transfer

  • Mismatched account information — name, address, or SSN differences between the two firms.
  • Margin or option positions — require receiving-firm approval before transfer.
  • Open trades — cannot transfer until settled.
  • Non-ACATS-eligible assets — proprietary funds, certain alternatives, restricted securities — handled separately.
  • Residual positions — fractional shares, dividend accruals — often transfer separately after the main batch.

Partial vs. full transfer

Clients can transfer specific positions or the full account. Partial transfers are slower and more error-prone — the receiving firm must specify exactly which positions, and reconciliation across the two firms takes longer.

Client communication best practices

  • Set expectations — 5-7 business days for clean transfers, longer for complex ones.
  • Communicate when trades cannot happen (during the transfer window).
  • Reconcile after settlement — verify all positions arrived, all costs basis preserved.
  • Address residual transfers as they arrive in subsequent weeks.

How StratiFi thinks about ACATS

ACATS transfers are operationally routine but produce a meaningful share of client friction in advisory practice. The firms that handle them well treat them as a workflow with explicit communication checkpoints — initiation, validation, settlement, reconciliation — and document each step in the client file. Done well, transfers happen in the background; done badly, they consume disproportionate time.

Frequently asked questions

  • How long does ACATS take?

    Typical clean transfers: 5-7 business days from initiation to settlement at the receiving firm. Complex transfers (margin, options, partial transfers) can take 10+ days.
  • Are all assets ACATS-eligible?

    Most publicly-traded securities held in cash or margin accounts are eligible. Proprietary funds, certain alternative investments, and restricted securities often are not — these transfer separately or sometimes cannot be transferred at all.
  • Can trades happen during a transfer?

    Generally no — once initiated, the delivering account is restricted. Pending trades complicate the transfer. Best practice is to settle all trades before initiating.
