Moving your investments from one brokerage to another used to mean selling every position, paying taxes on your gains, and rebuilding your portfolio from scratch — often over several weeks. What is an ACAT, and why does it change that calculation entirely? The Automated Customer Account Transfer Service (ACAT) is the industry-wide system that moves your holdings in-kind, keeping every share, ETF, and bond intact, with no forced [liquidation](/blog/define-liquidation) and no unnecessary tax event.

Many investors still believe switching brokerages requires a full cash-out first. That misconception keeps people locked inside accounts with high fees, outdated tools, or limited investment options for years longer than necessary. The reality is that ACAT transfers make moving a portfolio as straightforward as completing a single online form.

In this guide, you will learn exactly how an ACAT works step by step, which assets transfer and which ones don't, how long the process typically takes, and the specific mistakes that delay or derail transfers. Whether you're consolidating multiple accounts or moving to a platform with lower commissions, this guide covers everything you need to switch with confidence.

The DTCC — the [Depository](/blog/what-is-a-depository) Trust & Clearing Corporation — operates the ACAT system through its subsidiary, the National Securities Clearing Corporation (NSCC), processing hundreds of thousands of brokerage transfers every year across the U.S. securities industry.

## What Is an ACAT?

An ACAT is a standardized, electronic process that moves investment assets — stocks, bonds, ETFs, mutual funds, and other securities — directly between brokerage firms without requiring you to sell positions first. The Automated Customer Account Transfer Service was created by the NSCC to give investors a frictionless, industry-standard way to switch brokerages while keeping their portfolios completely intact.

Before ACAT existed, moving a brokerage account meant liquidating all positions, receiving a check, depositing it at the new firm, and manually repurchasing every holding. This process exposed investors to days of market risk, triggered capital gains tax events on profitable positions, and could take weeks from start to finish. ACAT eliminated all of that by creating a direct, electronic pipeline between brokerage firms — what the industry calls an **in-kind transfer**.

Today, virtually every major U.S. broker participates in the ACAT system: Fidelity, Schwab, Vanguard, Merrill Lynch, E*TRADE, and thousands of smaller registered investment advisers (RIAs). The system handles both **full transfers** — moving an entire account — and **partial transfers**, which let you move specific positions while leaving others in place.

The formal term you'll encounter in brokerage paperwork is often "ACATS transfer" (with an S), referring to the full system name: Automated Customer Account Transfer Service. The terms ACAT and ACATS are used interchangeably by most brokers and investors, so don't be confused when you see both.

## How the ACAT Transfer Process Works Step by Step

The ACAT process follows a standardized workflow governed by NSCC rules. From the moment you submit a transfer request to the moment assets arrive at the new broker, the entire cycle typically takes 5 to 7 business days. Here is exactly what happens at each stage.

*The four stages of an [ACAT transfer](/blog/acat-transfer), from initiation to settlement, completed in 5–7 business days.*

### Step 1: Initiate at the Receiving Firm

You always start the ACAT process at the **receiving firm** — the new brokerage where you want your assets to land. Most brokers provide an online transfer form labeled "Transfer an Account" or "Move an Account." You will need:

- Your account number at the **delivering firm** (the brokerage you're leaving)
- The exact name and title on the delivering firm's account
- Your Social Security Number or Tax ID
- Account type (individual taxable, joint, traditional IRA, Roth IRA, etc.)

The receiving firm submits your transfer request electronically through the ACAT system the same business day.

### Step 2: The Delivering Firm Validates the Request

Once the receiving firm submits the request, the delivering firm has **one business day** to validate or reject it. Rejection happens when account information doesn't match exactly — a misspelled name, wrong account number, or mismatched account type all trigger a rejection code.

If everything matches, the delivering firm approves the request and the transfer moves forward.

### Step 3: Assets Move to the Receiving Firm

After validation, the delivering firm has **three business days** to deliver the assets to the receiving firm. Stocks, ETFs, bonds, and most mutual funds move electronically through the DTCC's central clearing system. Cash in the account transfers simultaneously.

### Step 4: Settlement and Confirmation

The receiving firm posts the assets to your new account once the transfer settles. You'll receive a written confirmation from both firms. At this point, your full portfolio is accessible in the new account and the old account is closed or zeroed out.

## What Assets Can and Cannot Transfer via ACAT

Not every holding in your account is eligible for an ACAT transfer. Understanding which assets move in-kind and which must be liquidated beforehand prevents unexpected taxable events and account delays. Here is a clear breakdown of what the ACAT system supports and what falls outside its scope.

### Assets That Transfer via ACAT

Most standard investment securities transfer seamlessly:

- **Individual stocks** listed on [NYSE](https://www.nyse.com/), NASDAQ, and other major exchanges
- **Exchange-traded funds (ETFs)**
- **Corporate bonds, municipal bonds, and U.S. Treasuries**
- **Mutual funds** — with one important caveat noted below
- **Options contracts** — if the receiving broker supports options trading
- **Certificates of deposit (CDs)** held in brokerage form
- **Cash balances** in U.S. dollars

### Assets That Cannot Transfer via ACAT

Certain positions must be liquidated before or during the transfer:

- **Proprietary mutual funds**: If your current broker offers its own exclusive funds — think Fidelity's in-house funds held at a competitor — the receiving broker may not carry that product. Those shares must be sold before the transfer.
- **Alternative investments**: Private placements, hedge fund interests, and non-publicly-traded securities cannot move through ACAT.
- **Margin account debt**: Outstanding margin loans do not transfer automatically. You must either pay down the balance or negotiate a formal margin assumption agreement with the receiving firm in advance.
- **Unsettled trades**: Any positions with trades that haven't settled (typically T+1 for [equities](/blog/what-is-equities)) must complete settlement before the account can move.

If you hold non-transferable assets, you can liquidate them beforehand or use a partial ACAT transfer to move only the eligible positions while leaving the rest.

## ACAT vs. Non-ACAT Transfers: Which Should You Choose?

An ACAT transfer moves assets in-kind and preserves your original cost basis. A non-ACAT transfer involves selling your holdings, wiring cash, and repurchasing. Choosing the wrong method can trigger thousands of dollars in unnecessary taxes or delay your portfolio for weeks.

**Use an ACAT transfer when:**
- You have significant unrealized capital gains and want to avoid a taxable event
- Your holdings are standard, publicly-traded securities
- You want to preserve your current portfolio allocation exactly
- You're moving a tax-deferred account like a traditional or Roth IRA

**Use a cash (non-ACAT) transfer when:**
- Your current holdings are not ACAT-eligible
- The receiving broker doesn't participate in ACAT (rare, but possible with specialty platforms)
- You want to rebalance your portfolio at the same time you switch brokers

For most investors moving a standard taxable brokerage account or IRA, ACAT is the correct default. Because the transfer is in-kind, the [IRS](https://www.irs.gov/) does not treat it as a sale. There is no capital gains recognition, no step-up in cost basis, and no wash-sale risk. Your original purchase date and purchase price carry over intact.

## What Is an ACAT Freeze Period?

During the ACAT transfer window, your account at the delivering firm is typically frozen — you cannot place new trades, withdraw cash, or make changes to the account. This freeze begins once the delivering firm validates the transfer request and lasts until the transfer settles, usually 3 to 4 business days.

Plan your timing accordingly. Avoid initiating a transfer immediately before:

- A scheduled **dividend payment** (dividends declared but unpaid may not transfer cleanly)
- An **options expiration** date
- A **stock split** or **corporate action** affecting your holdings
- Any period where you expect to need quick access to your account

If timing is critical, consider a partial ACAT transfer — moving only specific positions — so the rest of your account remains fully accessible while the transfer processes.

## How Long Does an ACAT Transfer Take?

A standard ACAT transfer completes in 5 to 7 business days under NSCC rules. The clock starts when the receiving firm submits your request and the delivering firm validates it. Most major brokers — Schwab, Fidelity, E*TRADE — consistently complete routine transfers within this window.

However, several factors commonly extend the timeline:

- **Rejection at validation**: If your account details don't match exactly, the delivering firm issues a rejection code and the transfer resets. Fixing the discrepancy and resubmitting adds 1 to 3 business days.
- **Restricted securities**: Positions under a trading restriction or legal hold must be resolved before transfer.
- **Options in expiration week**: Options contracts near expiration are often excluded automatically to avoid settlement complications.
- **Manual processing**: Accounts with unusual asset mixes or alternative investments may require manual handling, adding additional time beyond the standard window.

Some brokers advertise "expedited" ACAT processing — typically 3 business days — but the NSCC floor still applies. In practice, most straightforward transfers land in the new account within one calendar week of initiation.

## Costs and Fees in an ACAT Transfer

ACAT transfers are free at the NSCC level — the clearinghouse charges brokerages nothing for processing standard electronic transfers. However, individual brokers set their own outgoing transfer fees, which can range from $0 to $100. Most receiving brokers will reimburse these fees to attract new clients.

As of 2025, common ACAT outgoing fees charged by the delivering firm include:

| Broker | Full Account Fee | Partial Transfer Fee |
|---|---|---|
| Fidelity | $0 | $0 |
| Schwab | $0 | $25 |
| Vanguard | $0 | $0 |
| E*TRADE | $75 | $25 |
| Robinhood | $100 | $25 |

The **receiving firm** almost never charges an incoming transfer fee. In fact, most major brokers actively reimburse outgoing fees — typically up to $75 to $100 — as a competitive incentive for accounts above certain minimums.

Before initiating a transfer, call the receiving firm's customer service line and ask specifically about their **ACAT fee reimbursement program**. Schwab, Fidelity, and E*TRADE have historically offered these reimbursements for qualifying account balances, effectively making the switch cost-free.

## Conclusion

Understanding what is an ACAT — and how to use it correctly — is one of the most practical pieces of financial knowledge for any investor who wants the freedom to move between brokerages without disrupting their portfolio or triggering unnecessary taxes.

Here are the key takeaways:

- **ACAT stands for Automated Customer Account Transfer Service**, the industry-standard electronic system managed by the NSCC for moving investment accounts between brokerages in-kind.
- **Always initiate at the receiving firm**, not the one you're leaving — this is where the majority of first-time transfer errors begin.
- **Standard securities transfer cleanly**: individual stocks, ETFs, bonds, options, and most mutual funds. Proprietary funds, private placements, and margin debt typically do not.
- **The process takes 5 to 7 business days** under NSCC rules; mismatched account information causing rejections is the leading source of delays.
- **Outgoing transfer fees** range from $0 to $100 depending on your current broker, and most receiving brokers will reimburse those fees to win your account.

Understanding these mechanics gives you real leverage: you are not locked into any brokerage, ever. Competition for your account works in your favor — better tools, lower fees, and smarter platforms are yours for the switching.
