Understanding the basic facts about transferring accounts between US brokerage firms can be help to avoid delays.  Through this article and other Knowledge Database resources, Interactive Brokers seeks to assist with your incoming and outgoing ACATS requests.

US brokerage firms utilize a standardized system to transfer customer accounts from one firm to another.  Known as the Automated Customer Account Transfer Service or ACATS, the process allows assets to move seamlessly between  brokerage firms in a unified time frame.   ACATS transfers are facilitated by a third party, the National Securities Clearing Corporation (NSCC), to assist participating members with timely asset transfers.

ACATS Transfer Benefits

The majority of assets may be transferred between US brokerage firms and some banks through ACATS.  This standardized system includes stocks, US corporate bonds, listed options, unit investment trusts, mutual funds, and cash.  Information on assets eligible for transfer is provided at "Assets Eligible..."  Though impacted by multiple factors and time constraints, the accepted or rejected transfers finalize within 10 business days in most cases.

 1. Incoming or Outgoing


Incoming ACATS Transfers

The financial institution that is receiving your assets and account transfer is known as the "receiving firm."  Investors always work with and through the "receiving firm" to move full or partial account assets into a new broker. 

Contact the "receiving firm" (Interactive Brokers) to review the firm's trading policies and requirements.  You should verify that your assets are eligible for trading at the "receiving firm" before initiating the transfer request.   Not all ACATS transferable assets are acceptable for trading at every brokerage firm.

Outgoing ACATS Transfers

All outgoing ACATS transfers, full or partial, must be approved by the "delivering firm."  Investors, however, should work with and through the "receiving firm" in order to begin the the transfer process or to status the progress of the request.      

Back to top

2. Initiating Your Transfer

Investors must always begin the ACATS transfer with the "receiving firm."  An ACATS transfer form or Transfer Initiation Form (TIF) must be submitted.  The "receiving firm" takes your reqeust and communicates with the "delivering firm" via ACATS.  The process begins with this request for transfer of the account. 

For your Interactive Brokers Account, the transfer is usually submitted online.  Video instruction on submitting the transfer is provided at "How to deposit funds via a full ACATS/ATON Transfer."  or through Step-by-step instructions.

Note: Outgoing account transfers from your IB account should be directed to the other broker.  Your request will be submitted to IB from the other broker through the ACATS electronically.

3. What to Expect

Your Account

Brokers ensure the safety and security of transfer requests by only authorizing requests between open accounts that meet the following criteria:

  • Same Account Title
  • Same Tax ID Number
  • Same Account Type

Transfer Approval

Ultimately responsible for validating the transfer,  the "delivering firm" may accept  information from the "receiving firm" correcting data originally entered.  Approved or validated requests result in the delivery of positions to the "receiving firm" for their acceptance.   Assets may not be accepted by the "receiving firm" for the following:

  • Non-marginable or Margin (credit) violation
  • Not Tradable
  • DTC Chill

Note: The most common reasons for ACATS rejections are outlined by clicking here.

Processing Time-frame

The processing time for each transfer request is fixed.  In general, approved transfers complete within 4 to 8 business days.  Almost all transfers complete within 10 business days.  Each firm is required to perform certain steps at specific intervals in the process.  Feel free to review the Full ACATS transfer process flow.



While Interactive Brokers does not charge a fee to transfer your account via ACATS, some brokers do apply a fee for full and partial transfers. Prior to initiating your transfer, you should contact the "delivering firm" to verify any charge.

IB Market Data Assistant

How to use the IB Market Data Assistant

Linking Accounts


Account linkage allows for individual account holders maintaining multiple existing accounts or seeking to open a new account the ability to group those accounts together.  In the case of a new account, linkage afffords the opportunity to open the account without having to complete a full application, with the account holder providing solely that additional information which is specific to the new account.  New account linkages are initiated either from the Account Management/Client Portal of the existing account (via the Settings > Account Settings > Create, Move, Link or Partition an Account menu options) or automatically when initiating a new application from the website. The following article outlines the steps for linking one or more existing accounts.

1) Login to Account Management/Client Portal and select the Settings and Account Settings menu options. 


2) On the Account Settings screen, you will see a section titled "Configuration". Click the Configure (gear) icon next to the words "Create, Move, Link or Partition an Account".


3) The Create, Move, Link or Partition an Account screen will list the various linkage options offered for your particular account. In order to link the account to one or more existing accounts, check the box to "Link All of My Existing Accounts Under a Single Username and Password" and click CONTINUE.


4) The Select Username screen will open and will list the accounts eligible for consolidation. Please note that there is no ability to consolidate a subset of the accounts. If a decision is made to consolidate, it must include all. In addition, while an account holder may place the consolidation request at any time, the actual consolidation takes place as of the close of business each Friday. 

5) Select which username you want to keep from the drop down menu. The screen will update to display the security device for the selected username. Once your accounts are linked, you will use the selected username and security device to login to any of the linked accounts. When finished, click CONTINUE.

6) You will be prompted to enter the username and password for each account to be linked, followed by additional authentication using your Secure Login device. Enter the username, password and authentication values for each account to be linked on the next screens, clicking CONTINUE to advance to the next screen.

7) We aggregate the financial information and trading experience information for all accounts to be linked. Verify your financial information and trading experience for the accounts to be linked, and then click CONTINUE.

8) Verify your account information and click CONTINUE. If you need to update your financial information, trading experience or account information, wait for those updates to be approved and then restart this linking procedure.

9) Verify any saved bank information you may have and click CONTINUE. Follow the remaining prompts on screen.

For information on how to cancel a linkage request, see Canceling a Pending Link Request.


* Once linked, account access to Account Management/Client Portal and the trading platform is accomplished using a single user name and password each of which will contain a drop-down window for selecting the account that the owner wishes to act upon.

* Linked accounts use the consolidated monthy commissions to calculate the Monthly Minimum Activity fee. Total commissions between the linked accounts must be at least (number of accounts) x USD 10 in order to avoid a fee. If the monthly consolidated commissions are less than this amount, an activity fee is charged on an account-by-account basis using the Standard Activity Fee calculcation. 

* As market data subscriptions are billed at a session level (i.e., user name) and only a single TWS session can be open for any one user at a given time, account holders previously maintaining subscriptions for multiple users have the opportunity to consolidate subscriptions to a single user.  Account holders wishing to view multiple TWS sessions simultaneously may add additional users (subject to separate market data subscribtions). In addition, only those market data subscriptions already associated with the surviving user name will remain in effect following consolidation.  Account holders maintaining different subscriptions across multiple users are advised to review those subscriptions subject to cancellation in order to determine which they wish to resubscribe to under the surviving user name.  Also note that the market data subscriptions either terminated or initiated mid-month are subject to billing as if they were provided for the entire month (i.e., fees are not prorated).

Message Center User Guide




Your Message Center allows you to submit questions directly to IB Customer Service in a secure and authenticated manner and provides the following features:
  • every inquiry is assigned a case number ("ticket"). This reference number can be used to efficiently track the progress of the inquiry.
  • the real-time status of an inquiry is always available via an overview screen. You will know if the issue has been picked up by an IB service expert, which expert is handling your issue, and whether it is being addressed by our main help team or by a specialty team.
  • both customers and IB staff can refine or add information to the ticket, permitting easy clarifications or follow up to the original inquiry. In addition, customers can cancel or close tickets once the issue has been addressed giving them greater control.
  • History Overview of both open and completed inquiries
  • Fast Response: Tickets will be assigned to an IB representative usually within a few minutes and always within 2 hours during European and North American trading hours. During Asian trading hours, response times may be longer.
This screen presents an overview of all inquiries in a tabbed view. 
  1. Open tickets are presented in the default view with date/time of submission, a brief description of the question, the most recent response from IB staff, the name of the IB Expert handling the inquiry, and a status indicator.
  2. A second tab shows closed or resolved inquiries going back 1 month.  This allows customers to refer to the solutions or information provided by IB and save them on their computers in a document system of their choice (simple cut-and-paste). Status indicators allow customers to know at a glance where their inquiry is in the process.  A key for the meanings of the various states are provided at the bottom of the overview screen. Action buttons (edit/view, close, cancel) permit customers to manage their inquiries directly.  
  • Resolve/Close : use this when you are satisfied with the response provided by the IB service expert. This will move the ticket onto the "Closed" tab.  Please note that IB staff may also close a ticket if they feel the inquiry has been completely addressed.
  • Cancel Ticket allows customers to retract an inquiry even if it has not yet been fully addressed.
  • Edit/View: customers can add additional information to an inquiry or respond back to an IB Expert's request for more detail.
  1. Click New Ticket in the menu bar. This will open a new window (you must allow pop-ups on your browser).
  2. Select the main Category and a SubCategory for the inquiry. The category will allow us to route your inquiry to the IB Expert who is specialized or is most experienced for your issue. We recommend choosing the category accurately to get the highest quality and speed of response.
  3. Enter a brief summary of the question.  This is the text you will see in the overview screen.
  4. Enter details about the problem as needed. Please be as specific and complete as possible (for example, exact dates/times, TWS version, etc) , as this will allow us to accurately research your inquiry to give you the best / fastest response.
  5. Click "Next".  This will take you to a confirmation screen that will allow you to review and submit your inquiry
  6. You will get a confirmation of receipt along with a ticket reference number.  Note this reference number (it is also viewable on the Overview Screen) and please use it in any follow up to your inquiry (for example, over chat or by phone).
  7. The inquiry will show in the Overview Screen with the status=New.
  1. On the Overview Screen, select the open ticket you wish to update, and click on the Edit icon at the end of the row.
  2. A new window will open showing the history of the "conversation" to date, along with a text entry box for the new information to be added.
  3. Click "Send" to submit. After some seconds, you will get a confirmation from IB that the update has been received by our system.
  1. On the Overview Screen, select the open ticket you wish to update, and click on the paperclip icon.
  2. A new window will open showing the history of the "conversation" to date, along with a text entry box to add information about the attachment(s).

  3. Click "Send" to submit. After some seconds you will be fowarded to the preview ticket mode where the attached file(s) name will be visible in the comment section.
To Cancel an Existing Open Ticket:
  • Use this when your inquiry has been resolved outside of the IB CIMS environment (for example, an exchange access problem that has already been fixed). This will move the ticket to a "Closed" state (CLS) immediately and will inform IB staff that there is no further need to investigate the issue.
  1. Just click on the Cancel on the appropriate ticket row. A confirmation page will be provided.
To Close/Resolve a Ticket
  • Use this when you have received a satisfactory answer to your inquiry. This will change the ticket state to "Closed" (CLS). We request that you close tickets as soon as possible once you are satisfied. IB Customer Service managers may close tickets in cases where the ticket appears to be fully answered but has not been closed by the customer.
  1. Just click on the Close icon on the appropriate ticket row. A confirmation page will be provided.
To Reopen a Ticket
  • The IB-Expert might close a ticket after responding if he/she believes the inquiry was fully and satisfactorily resolved. It may be the case thaat the Client does not agree that the question was properly answered so we provide a way to reopen recently closed tickets. Just click on the Re-Open link on the appropriate line of the overview page. The ticket status should show LV1 and the IB-Expert who handled the ticket will be notified.
  1. Just click on the "Reopen" link on the appropriate ticket row. A confirmation page will be provided.
There are a million possible questions and IB staff cannot possibly know all answers to all the possible questions equally well. Proper selection of the Category for your inquiry will allow IB to assign the best qualified Expert to your inquiry. It may take a few seconds more to find the right Category/SubCategory combination but this small time investment will be rewarded by a faster and higher quality response.
Customers can provide feedback to IB management regarding their service experience. Feedback surveys consist of four questions relating to overall experience, quality and speed of answer and courtesy which you are asked to rate.  Respondents also have the option to submit free form comments requesting additional follow-up or in recognition of exemplary service.  Feedback surveys are made available immediately upon closure of a chat session or webticket and are periodically sent via email following a telephone inquiry. While all surveys are not responded to, each is reviewed by our Quality Assurance team as a means of improving the overall quality of our service.


Setting Communication Preferences

As a convenience for customers who wish to monitor the receipt and content of communications delivered to their Message Center, IB will periodically scan your Message Center for communications which have not yet been read and send an email notifying you of them.  The frequency of these emails depends upon the  priority level of your unread communications, with a notification frequency set to hourly in the case of 'High' priority communications, once every 6 hours where the priority is 'Normal' and once every 12 hours where the priority is 'Low'.

In addition, customers may set their preference for the manner in which the content of these communications is displayed in the email.  The two preference settings available are Secure and Non-Secure: 

1. Secure - under the Secure setting the contents of the communication will not be provided in the body of the email.  The email will simply serve as a notice that the contents of the communication are available for viewing upon log into your Message Center within the secure Account Management application. 

2. Non-Secure - under the Non-Secure setting the full contents of the communication will be provided in the body of the email. While this doesn't require that you log into your Message Center to read the communication, in the event the communication is a response to an Inquiry Ticket you've initiated and you wish to provide a follow-up response, you will need to log in to post that response.



As commercial email is considered a form of communication which is inherently vulnerable to hacking, the default delivery preferences for all communications is set to Secure.  If you wish to change your delivery preferences, you may do so by first logging into Account Management and selecting the tab labeled Support and then Message Cente.  From the Message Center, click on the Preferences link located in the upper right hand corner of the screen (circled in red below).

A Message Preferences window will open which provides you the ability to specify by message type (e.g., Ticket Inquiries/Responses, General Notices, etc.) your subscription election (note that certain message types require subscription) and the available Delivery Modes by which you'd like messages sent. If a Delivery Mode of email has been selected for any message type, you will also be prompted to specify your Secure or Non-Secure delivery election to be applied to all emails regardless of message type.


2009 Gain/Loss Summary Worksheet: General Explanation

Important Note:  The Worksheet has been prepared using IRS guidelines for information purposes only.  It is not intended to replace any official IRS tax forms or schedules; and should not be regarded as an IRS Form Schedule D.

Interactive Broker's 2009 Gain/Loss Summary Worksheet ("Worksheet") provides the capital gains and losses for your account's year-end review.  Investors of a limited number of securities will find the pairing of 2009 sell trades useful.  Designed to aid with your year end reconciliation, the following securities and trades are included: Bonds, Equity Options, Fractional Shares, Index Futures*, Mutual Funds, Short Sale, T-Bills, Tender Offers, and WHIFITs.

A general explanation of the Worksheet is organized below by Parts, Columns, and Totals.

 *Only cash-settled

Worksheet Parts

The Worksheet is divided into two parts.  The period in which you held the position determines whether or not Short-Term or Long-Term applies. 

Part 1 - Short Term Capital Gains and Losses - Assets Held One Year or Less

Part 2 - Long Term Capital Gains and Losses - Assets Held More Than One Year

Worksheet Columns

Each section contains the following seven columns to identify your trades.

(a) Description of property (b) Date acquired (c) Date sold (d) Sales price (e) Cost or other basis (f) Gain or (loss) Codes

1.  (a) Description of property...shows the security symbol, name, quantity, and other information to identify the asset sold.


2.  (b) Date acquired...shows the trade date of your security's purchase. 

Asset Transfers:  IB has entered the date supplied by you through Position Transfer Basis.  If an update was not received by year-end, then the asset transfer settlement date appears. See your monthly or annual summary for details. 

Short Sales:  The box is left blank if the closing trade has not been completed.  For short sales included on a prior year Worksheet or 1099-B, the code ADJ is entered.

3.  (c) Date sold...shows the trade date of your security's sale.

4.  (d) Sales price...shows the gross security sale price, net of commissions. 

Option Adjustments:  For exercised call options, the writer's sale proceeds have been increased by the amount received for the call. For exercised put options, the holder's sale proceeds have been reduced by the cost of the put. See IRS Pub. 550, page 57, for details.  For expired options, an amount of 0.00 is entered, followed by the Code "Ep".

5.  (e) Cost or other basis...shows the total price paid for your security, plus commissions.

Corporate Actions:  Adjustments have not been made for any stock splits or non-dividend distributions. See IRS Pub. 550, page 44, for details.

Mutual Funds:  IB does not use an average basis for mutual funds. The First In, First Out (FIFO) method is used.

Original Issue Discount:  The basis has not been increased by the amount of OID included in your income. See IRS Pub. 550, page 13, for details.

Option Adjustments: For exercised put options, the writer's basis has been increased by the amount received for the put.  For exercised call options, the holder's basis has been increased by the cost of the call. See IRS Pub. 550, page 57, for details.

6.  (f) Gain or (loss)...shows the calculation for each security using the tax execution methods First-In, First Out (FIFO), Last In, First Out (LIFO), or Maximize Losses (ML). 

Loss: Negative amounts are identified in parentheses.  For example, a loss of $2,000.00 displays as (2,000.00).

Tax Method:  If no code appears in the Codes column, then FIFO applies.  The other methods are noted by either LI = LIFO or ML = Maximize Losses.

7.  Codes...shows various trade designations, such as: corporate actions, asset transfers, or option assignments.

Codes and Meanings Table:  The last page of the Worksheet contains a table to identify each non-security symbol used.

Worksheet Totals

1. Subtotal adjustment from option assignment...shows the total amount of all sale proceeds increases or decreases made from option assignments to the assigned stock sale proceeds (see Cost or other basis details above). 

The adjustments, in accordance with IRS guidelines, are added or subtracted in order for the next Subtotal line to equal the amount reported by IB on the 1099-B, box 2.  Please keep in mind that IB does not report any option proceeds or adjustments to sales proceeds from assignments on the 1099s.

2.  Subtotal for stocks, bonds and T-bills...shows the total non-adjusted proceeds reported for each trade under column (d) Sales price for stocks, bonds, and T-bills only.  This amount should equal the 1099-B, box 2, amount. 

1099-B, box 2:  In general, this 1099 figure should equal the combined Parts 1 & 2 Subtotal for stocks, bonds and T-bills figure.

3.  Total...shows the combined proceeds for all trades under column (d) Sales price, including option sale proceeds.

Total Option Sale Proceeds:  Subtract the Total amount of column (d) from the Subtotal for stocks, bonds and T-bills of column (d) to obtain the total proceeds from all option sales.

Username and password management for the IBKR Online Features


IBKR Online Features provides several forums where clients can express their opinion and vote for their favorite commercial or freelance software tools, programming features and third-party tutors.  In addition, the Features Poll forum allows clients to submit suggestions for future technology and service enhancements and to vote and make comments on the suggestions provided by others.  While there's no assurance that any one suggestion will be enacted, those which generate the widest support via this system tend to receive the highest priority in our programming queue.


To participate in a forum, clients must first establish a username and password combination unique from that established for Account Management and trading platform access.  To add, delete or modify a username or password, you'll first need to log into Account Management and go to the Settings section followed by User Settings. Once there, click the gear icon next to the words "Online Features" in the Login section. From there enter a username and password which differs from that which you use to log into your account.  Then enter your account username and password to confirm.

If you have forgotten your Online Features password and/or wish to reset your username, you may do so through this same screen by re-entering your choices, then entering your account username and password to confirm and clicking on the Change button. As clients have the availability to self-manage their password in this manner there is no process in place to supply a forgotten password.

How do I determine which market data subscription is applicable for a given security?

IBKR provides account holders with a Market Data Assistant tool which assists in selecting the subscription services available for a given security (stock, option or warrant) they wish to trade.  The search results show all exchanges upon which the product trades, the subscription offering and its monthly fee for both Professional and Non-Professional clients as well as the depth of market variations associated with each subscription.

To access the Market Data Assistant, login to Client Portal and select Support from the navigation menu. Click the option for the Market Data Assistant. From there you may search by entering either the symbol or ISIN for the product in quesiton. Results may be further filtered by specifying the exchange, Professional or Non-Professional designation and/or the security's currency of denomination.

Glossary terms: 

Security considerations following SLS opt out


Account holders who have elected to opt out of IBKR's Secure Login System (SLS) effectively relinquish the protections afforded by Two-Factor Authentication. They are strongly encouraged to utilize alternative security measures, with one of those being the IP Restrictions. By selecting this setting through Client Portal, you're telling Interactive Brokers that you only want access to your trading platforms from a specified IP address. In addition, should you have multiple authorized traders for a given account, these restrictions can be set at the individual trader level by the master user of the account. 


Preliminary checklist:

Before setting up the IP Restrictions, you will need to:

  • Know your WAN IP Address. That is the IP address exposed on the external (Internet) side of your network and it is different from your local IP address (called as well LAN IP address). If you trade from a company office, you can ask your IT or Networking department for the WAN IP address of your computer. If you connect to the Internet through a private broadband/cable/satellite connection you can get this information from your ISP (Internet Service Provider).
  • Make sure that your IP address is static. This means your IP address will always remain the same, and will not change upon router/modem reboot or after a certain time period. The same entities which provided you with the WAN IP address, can as well clarify whether it is a static or dynamic one.
  • Be aware that IP Restrictions are not effective immediately. Our systems apply the filters during their daily overnight restart. It can take up to 24 hours until they are active, depending on the time you submit your IP Restrictions request. The same applies when you modify or remove existing IP Restrictions. Please be sure to consider this when you are planning your course of action.
  • The IP Restrictions will be applied to ALL Trading Platforms offered by IBKR. It will not affect Client Portal access, which will remain accessible from any IP address.


Please take note that the technical ability to misrepresent one's IP address exists, and full account protection is only ensured by using SLS Two-Factor Authentication (

If you have any questions on the topic, please feel free to contact IBKR's Technical Assistance Center.

How to set the IP Restrictions:

  1. Login to Client Portal and click the menu icon in the top-left corner.
  2. From the left side menu, click on Settings, then on User Settings. Then click on the wheel (configure) icon next to IP Restrictions.
  3. You will see a brief description of the effects of IP Restrictions. To set up a new IP Restriction, click on Add IP Restriction.
  4. Select the Trader from the drop-down list and enter the IP Address (in the format you want to allow for him. Then click on Continue.
  5. If you logged into Client Portal without using the Two-Factor Authentication, you will now receive an email1 containing a Confirmation Number. Enter it in the Confirmation Number field. Once done, click on Continue to submit the request. If you logged in to the Client Portal using a security device, please proceed directly to point 6.
  6. If the operation completed successfully, you will see a confirmation screen. Click OK.
  7. The system will now list your active IP Address restrictions. Should you want to create an additional one, click again on Add IP Restriction, otherwise navigate away from this section


Opt-out and IP Restrictions for Penny Stocks traders:

Clients who have elected to perform an opt-out, thus using the Two-Factor Authentication only for the Client Portal, must activate the IP Restrictions in order to be able to activate Penny Stocks Trading Permissions.

Additional best practices for securing your computer and your network

  • When logging into the TWS, activate the checkbox “Use SSL” on the login screen. SSL (Secure Socket Layer) guarantees that all the information exchanged between your computer and our servers is protected using 128-bit encryption.
  • Use a firewall to prevent unauthorized access to the services exposed by your network or/and computer. During the firewall set-up, please make sure you authorize the host/ports listed in section DESKTOP TWS of KB2816.
  • Use antivirus software to identify and eliminate viruses which might have infected your computer.  As new viruses are constantly being created, you need to update the threats database of your antivirus software regularly.
  • Use anti-malware software to detect and remove spyware/malware programs which can collect various types of personal information, monitor your browsing activity and interfere with the control of your computer. Nowadays many antivirus solutions include a built-in anti-malware protection.
  • Refrain from using wireless connections (Wi-fi) which are public, unsecured or not operated by you. If the use of a unsecured network (e.g. public Wi-Fi hotspot) becomes necessary, do not log into any financial institution account you may have, including your IBKR account.


1. If you have not received the email, please make sure it did not land in the Spam/Junk folder of your mailbox and possibly add the email addresses and to the trusted senders list. You can then request a new email to be sent to you with the button Resend Confirmation Number.
