ACAT Transfers for Advisors: The Timing, the 12 Rejection Reasons, and What Won't Move

When an account transfer stalls, the client calls you, not the custodian. Most of the time the cause is on the transfer form: a name spelled differently from the old statement, an account type that doesn’t match, a signature missing. The rules that govern these transfers are specific, public and short, and knowing them turns most rejections into things you catch before you submit.

This guide covers transfers between brokerage firms under FINRA Rule 11870, commonly called ACAT transfers after the system that runs them. It is written for advisory firms whose clients hold assets at a custodian. It is not legal or tax advice. Your custodian’s current requirements win wherever they differ from anything here.

One scope note first. Rule 11870 is a FINRA rule, so it binds FINRA member broker-dealers. When your custodian is a broker-dealer, these are the rules it and the client’s old firm work under. Your firm fills in and submits the paperwork; the clocks below belong to the two firms moving the assets.

How an ACAT transfer works

The client signs a transfer instruction, often called a TIF (transfer initiation form), with the new firm. The new firm, called the receiving firm, submits it through ACATS. The old firm, called the carrying firm, then validates it or takes exception to it, and the assets move.

ACATS is run by DTCC. In its own words, the Automated Customer Account Transfer Service “automates and standardizes asset transfers from one broker-dealer, firm or bank to another” (DTCC). DTCC says it supports “equities, corporate and municipal bonds, unit investment trusts, mutual funds, options, annuities, alternative investments and cash.”

A transfer can move the whole account or part of it. Rule 11870 covers transfers “in whole or in specifically designated part”, and says the automated capabilities “shall be utilized for partial transfers” unless otherwise indicated (FINRA Rule 11870). The client’s authorization can be “the customer’s actual signature, or an electronic signature in a format recognized as valid under federal law.”

The clock: what Rule 11870 requires

Two deadlines define an ACAT transfer:

1. Validate or take exception: one business day. The carrying firm must, “within one business day” of receiving the transfer instruction, either validate it or “take exception to the transfer instruction for reasons other than securities positions or money balance discrepancies.”
2. Complete the transfer: three business days after validation. “Within three business days following the validation of a transfer instruction, the carrying member must complete the transfer of the customer’s security account assets to the receiving member.”

A caution if you look this up. FINRA’s own Key Topics page describes the first step as “within three business days” (FINRA). The rule text says one business day. This guide follows the rule text. The rule also says these time frames can change “as determined from time-to-time in any publication, relating to the ACATS facility, by the National Securities Clearing Corporation (NSCC).”

Every step in the rule has its own deadline:

Step	Who acts	Deadline	Where it comes from
Validate or take exception	Old firm	1 business day	Rule 11870(b)(1)
Complete the transfer	Old firm	3 business days after validation	Rule 11870(e)
Act on the client’s instructions for assets that can’t move	The firm that asked	5 business days after instructions arrive	Rule 11870(c)(5)
Resolve a claim	The firm receiving the claim	5 business days	Rule 11870(g)(3)
Pass on dividends and credits that arrive late	Old firm	Within 10 business days of accruing, for at least 6 months	Rule 11870(n)(2)
Send cost basis information	Old firm	Within 15 days after settlement	26 CFR 1.6045A-1(a)(3)

Why real transfers take longer

The deadlines above run from the moment each step starts. In practice the SEC’s investor bulletin describes a transfer as taking “approximately three to five business days to complete from the time the new firm enters the transfer form into ACATS” (Investor.gov). That bulletin dates from 2014. Since then DTCC removed a step from the cycle: its training site notes the first day a transfer skipped the “Settle Prep” stage was “Friday, October 17, 2025” (DTCC Learning).

What adds days:

• An exception. The transfer stops until the problem is fixed and resubmitted.
• Retirement and custodial accounts. FINRA says transfers of “accounts requiring a custodian, like an individual retirement account (IRA) or a custodial account for a minor child, may also take additional time” (FINRA).
• Assets outside ACATS. The SEC bulletin says “It is not uncommon for the account transfer process outside of ACATS to take up to thirty (30) days.”
• Annuities. They are on delayed delivery (more below).

The 12 reasons a transfer can be rejected

Rule 11870 is precise about this. The old firm “may take exception to a transfer instruction only if” one of 12 things is true. Just as important is what it can’t do: it “may not take exception to a transfer instruction […] because of a dispute over securities positions or the money balance in the account to be transferred.” A disagreement over what the account holds, or what it’s worth, is not a reason to hold up the transfer.

Here are the 12, with the check that prevents each one:

The rule’s reason	How to prevent it
Additional documentation is required (for example a death or marriage certificate)	Ask about recent deaths, marriages, divorces and name changes before you prepare the form
The account is “flat” and has no transferable assets	Confirm on a current statement that the account holds something
The account number is invalid	Copy the account number from the latest statement, not from memory or an old form
It is a duplicate request	Check whether a transfer is already in progress before resubmitting
It violates the old firm’s credit policy	Ask about margin balances, debits and pending trades
It contains unrecognized residual credit assets	Review the latest statement for small cash or share balances
The client rescinds the instruction	Confirm the client still wants to move before submitting
The Social Security number or tax ID doesn’t match	Match the SSN or TIN to the old statement and the client’s ID
The account title doesn’t match the old firm’s records	Copy the title exactly as it appears on the old statement
The account type doesn’t match the old firm’s records	Match the type (individual, joint, IRA, trust) to the old account
The authorization is missing or improper (for example a second owner’s signature, or the successor custodian’s acceptance)	Get every required signature, and the custodian’s acceptance for retirement accounts
The client has taken possession of the assets	Confirm nothing is being withdrawn or moved in the meantime

Two details worth knowing. If the account came back “flat”, the new firm “may re-submit the transfer instruction only if the most recent customer statement is attached.” And the SEC’s advice to investors is the single best prevention tip there is: “Be sure to provide the requested information exactly as it appears on your old account.” The same bulletin says “Most account transfer delays occur because the TIF is either incorrect or incomplete.”

The new firm has limits too. It can reject a transfer “only if the account is not in compliance with the receiving member’s credit policies or minimum asset requirements”, and it may only reject the entire account for those reasons, not part of it.

What can’t move: nontransferable assets

Some assets can’t move through ACATS as they are. Rule 11870 defines a nontransferable asset as one “incapable of being transferred from the carrying member to the receiving member because it is”:

• “a proprietary product of the carrying member”, such as the old firm’s own funds, unless the new firm agrees to accept it
• “a product of a third party (e.g., mutual fund/money market fund) with which the receiving member does not maintain the relationship or arrangement necessary to receive/carry the asset”
• “an asset that may not be received due to regulatory limitations on the scope of the receiving member’s business”
• “a bankrupt issue” that can’t be delivered or re-registered
• “an issue for which the proper denominations cannot be obtained”, with “foreign securities, baby bonds” given as examples
• “limited partnership interests in retail accounts”

The SEC’s investor bulletin separately lists fractional shares among assets that may not transfer. That comes from SEC investor guidance, not from the rule’s list.

Your client’s choices

When assets can’t move, the firm must give the client “a list of the specific assets” and ask “in writing” for instructions. For the old firm’s proprietary products, the choices are:

1. Liquidation, “with a specific indication of any redemption or other liquidation-related fees”
2. Leaving them at the old firm for the client’s benefit
3. Transferring them “physically and directly, in the customer’s name to the customer”

For third-party funds the new firm can’t carry, there is a fourth option: transfer “to the third party that is the original source of the product”, which usually means the fund company. Once the client decides, the firm must act “within five (5) business days following receipt of the customer’s disposition instructions.”

FINRA has also been clear that a firm can’t quietly drop assets from a transfer: “a member may not remove an asset from an ACATS transfer unless the member has determined that the asset is a ‘nontransferable asset’ as defined in Rule 11870” (FINRA Regulatory Notice 22-19).

The practical move: before you submit, read the client’s latest statement for anything proprietary to the old firm and anything your custodian doesn’t hold, and get the client’s decision on those positions up front. That turns a surprise letter into a conversation you already had.

Annuities and a few others run on a different clock

The rule treats three kinds of asset as delayed delivery and exempts them from the three-day completion requirement: “(A) insurance policies (annuities); (B) stripped coupons; (C) when-issued or when-distributed securities.” For annuities, the SEC bulletin says the old firm “will use the ACATS system to change the ‘broker of record’ to your new firm.” Tell clients with annuities to expect that part to finish later than the rest.

During and after the transfer

The freeze

Once the old firm validates the transfer, “all open orders, with the exception of option positions that expire within seven (7) business days, must be canceled and no new orders may be taken.” In the SEC’s plainer words, “the account is frozen for transfer to the new firm.” Warn clients who trade actively before you submit.

For a whole-account transfer of a non-retirement account, the client also has to confirm they have “destroyed or returned to the carrying member any credit/debit cards and/or unused checks.”

Dividends and interest that arrive late

Income often lands in the old account after the transfer. For whole-account transfers, the old firm must, “for a minimum period of six (6) months after the transfer […] is completed, […] transfer credit balances (both cash and securities) that occur in such transferred account assets within (10) ten business days after the credit balances accrue to the account.” The rule also requires it to “promptly distribute to the receiving member any transferrable assets that accrue to the account after the transfer.”

Cost basis

Your client’s tax picture should follow the assets. Under IRS regulations, a firm that transfers custody of a security “must furnish to the receiving broker a transfer statement”, and must do it “within fifteen days after the date of settlement for the transfer” (26 CFR 1.6045A-1). The statement includes “The total adjusted basis of the security, the original acquisition date of the security.” Basis doesn’t have to be sent for a position the statement identifies as a noncovered security, so check any of those with the client.

Beneficiary designations

Don’t assume transfer-on-death or beneficiary designations come along. FINRA’s advice: “Should you ever transfer an account to another firm, double-check with the firm to be sure that any beneficiary designations also transfer” (FINRA). Put a beneficiary check on your post-transfer list.

Retirement accounts: transfer or rollover

Moving retirement money has its own rules, and choosing the wrong method can cost the client real money. The IRS describes three ways (IRS):

Method	How it works	Withholding	One-per-year limit	Deadline
Trustee-to-trustee transfer (IRA to IRA)	The old IRA custodian pays the new one directly	”No taxes will be withheld”	Does not apply	None set by this rule
Direct rollover (employer plan to IRA or plan)	The plan administrator pays the new account directly	Does not apply when rolled over directly	Does not apply	None set by this rule
60-day rollover	The money is paid to the client, who deposits it	20% for employer plan payouts; 10% for IRA payouts unless the client opts out	Applies to IRA-to-IRA rollovers	60 days from receipt

The rules behind that table, in the IRS’s words:

• The 60-day rule. “You have 60 days from the date you receive an IRA or retirement plan distribution to roll it over to another plan or IRA.” The IRS “may waive the 60-day rollover requirement in certain situations.”
• One rollover per year. “you can make only one rollover from an IRA to another (or the same) IRA in any 12-month period, regardless of the number of IRAs you own.” Trustee-to-trustee transfers don’t count, because “this type of transfer isn’t a rollover.”
• Withholding. “A retirement plan distribution paid to you is subject to mandatory withholding of 20%, even if you intend to roll it over later. Withholding does not apply if you roll over the amount directly.” And if the client does a 60-day rollover, “you must use other funds to make up for the amount withheld.”

For IRA-to-IRA moves, a trustee-to-trustee transfer avoids both the withholding and the one-per-year limit. For employer plans, a direct rollover avoids the 20% withholding.

Two more rules touch retirement transfers. Under Rule 11870, the new firm must get “the approval of its custodian/trustee accepting a customer’s retirement plan securities account before submitting a transfer instruction.” And if your firm is SEC-registered, recommending that a client “roll over assets from a retirement account into a new or existing account or investment” is one of the events that requires you to deliver your current Form CRS again (17 CFR 275.204-5).

Fees

Transfers can cost the client money. The SEC bulletin says “Your old firm may charge you a fee to cover the administrative expenses associated with the transfer, and the new firm may also charge a fee,” that “Sometimes, transfer fees can be substantial,” and that “some firms will charge a ‘transfer out’ as well as a prorated retirement account custodial fee.” Its suggestion is to “approach your new firm and ask them to waive or reimburse you for any transfer fees.”

For retirement accounts, Rule 11870 says outstanding custodian fees “must be deducted from the credit balance” or, if there isn’t enough cash, assets “must be liquidated to the extent necessary to satisfy such fees.” Tell clients about both before the transfer, not after.

A pre-submission checklist

Everything above comes down to what leaves your office. Run these before any transfer goes in:

• Latest statement from the old firm is on file for every account being moved
• Account title copied exactly from that statement
• Account type matches the old account (individual, joint, IRA, trust, custodial)
• Account number copied from the statement
• SSN or TIN matches the statement and the client’s ID
• Every required signature is on the form, including joint owners
• For retirement accounts, the receiving custodian has accepted the account
• Recent deaths, marriages, divorces or name changes are documented
• Proprietary funds and anything your custodian can’t hold are identified, and the client has decided what to do with them
• Annuities are flagged for the client as finishing later
• Margin balances, pending trades and open orders are discussed with the client
• Transfer and custodial fees are disclosed to the client
• For a recommended rollover, Form CRS has been redelivered (SEC-registered advisers)
• A reminder is set to confirm cost basis and beneficiary designations after the transfer

The first five rows share a cause. When the same client’s details are typed separately into an application and a transfer form, each copy is a chance for a difference. Filling every form from one record removes that chance. That is what Finpace does: Emma reads the client’s statement and ID into one profile, and the transfer form fills from it. Finpace doesn’t come with pre-mapped custodian forms; you upload the ones you use, and Emma learns where each field goes.
