IBKR Advisor Family Account Allocation Profiles (2026)

Managing multiple investment accounts for family members, clients, or trust beneficiaries can be a logistical nightmare. If you are using Interactive Brokers, the Advisor Family Account feature is designed specifically to solve this problem. By linking individual accounts together, you can manage them from a single dashboard, execute consolidated trades, and—most importantly—set up allocation profiles to distribute trades across different accounts automatically.

In this guide, we will break down exactly what Advisor Family Accounts are, how to set them up, and how to use allocation profiles to automate your trading workflow across multiple IBKR accounts.

About this guide: I'm Lawrence, the writer behind supa.is. Between February and May 2026 I've published 150+ articles on supa.is across crypto and brokerage tooling — including 30+ Interactive Brokers-specific guides (recent examples: IBKR Account Setup, IBKR Bracket Order, IBKR Python API). The most-repeated reader question across that IBKR archive is exactly how to manage multiple accounts efficiently, which is why I'm publishing this standardized guide instead of answering one-off.

What Is an Advisor Family Account?

An Advisor Family Account is a feature within Interactive Brokers that allows a primary account holder (the "Advisor") to link multiple individual accounts (the "Family" or "Sub-accounts") under a single umbrella.

Instead of logging out and back in to check balances or place trades across five different accounts, you log into your primary Advisor account and see everything in one place.

This is incredibly useful for:

* Parents managing accounts for children (e.g., UTMA/UGMA accounts). * Family offices managing wealth for multiple relatives. * Financial advisors managing client portfolios. * Trustees overseeing trust accounts.

Once the accounts are linked, you can execute a single trade and have it automatically split across the linked accounts based on specific allocation rules. This is where Allocation Profiles come in.

Why Use Allocation Profiles?

Allocation profiles are pre-defined rules that tell IBKR how to split a trade across your linked accounts.

Imagine you want to buy $10,000 worth of Apple (AAPL) stock, and you want it distributed equally across three family accounts. Without an allocation profile, you would have to log into each account (or switch accounts in TWS) and place three separate $3,333.33 orders.

With an allocation profile, you place *one* order for $10,000, and IBKR automatically routes $3,333.33 to each account.

This saves time, ensures consistency across portfolios, and reduces the risk of manual errors.

How to Set Up an Advisor Family Account

Before you can use allocation profiles, you need to set up the Advisor Family Account structure.

Note: Steps below are reconstructed from official docs (linked). Verify each step against the current UI before relying on it.

Log into your primary Interactive Brokers account using Trader Workstation (TWS) or the Client Portal.
Navigate to the Advisor section. In TWS, this is typically found under Advisor > Advisor Family Account or through the Client Portal under Account Management > Advisor.
Add Family Members / Sub-Accounts. You will need the account numbers of the individual accounts you want to link. If you are setting up new accounts for family members, you will need to open them first and then link them.
Define Permissions. You can choose what level of access the Advisor has. Typically, you will want full trading and reporting access to manage the accounts effectively.
Save the Configuration. Once the accounts are linked, they will appear in your Advisor dashboard.

If you are just getting started with IBKR and need to open your first account, you can Open an IBKR Account to get started.

How to Create and Use Allocation Profiles

Once your accounts are linked, you can create allocation profiles. Here is how the process works in Trader Workstation (TWS):

Step 1: Create the Allocation Profile

Open TWS and log in to your Advisor account.
Go to the Advisor tab at the top of the screen.
Select Allocation Profiles from the dropdown menu.
Click New to create a new profile.
Name your profile (e.g., "Equal Split Family" or "Weighted Trust").
Select the accounts you want to include in this profile.
Set the allocation method:

* Equal Allocation: Splits the trade equally across all selected accounts. * Percentage Allocation: You define the exact percentage for each account (e.g., Account A gets 50%, Account B gets 30%, Account C gets 20%). * Cash Balance Allocation: Splits the trade based on the available cash in each account (useful if accounts have different funding levels).

Click Save.

Step 2: Execute a Trade Using the Profile

Open the Order Ticket for the security you want to trade.
Fill in the standard order details (Action, Quantity, Price, etc.).
Look for the Allocation or Advisor section in the order ticket.
Select the Allocation Profile you just created from the dropdown menu.
Place the order.

IBKR will execute the order and automatically split the fills across the accounts according to your profile. You will see the individual fills in each account's activity statement.

Common Allocation Strategies for Families

When setting up allocation profiles for family accounts, you generally have three main strategies:

Equal Split

The simplest approach. If you have three children with UTMA accounts and want to buy the same amount of an ETF for each, an equal split profile is perfect. Buy $1,000 of VOO, and each account receives $333.33 worth of shares.

Percentage Weighting

Not all family accounts are equal. You might have a primary spouse account holding 60% of the family's liquid assets, and two trust accounts holding 20% each. A percentage-weighted profile lets you replicate the overall family portfolio allocation in a single trade. Place a $10,000 trade, and the primary account gets $6,000 while each trust gets $2,000.

Cash Balance Pro-Rata

If your family accounts are funded irregularly, a cash balance allocation profile dynamically adjusts the split based on available buying power. It ensures you don't over-concentrate a trade in an account that has plenty of cash while leaving an under-funded account behind.

Tips for Managing Advisor Family Accounts

* Keep Account Names Clear: When setting up the sub-accounts, use clear naming conventions (e.g., "John Doe UTMA", "Jane Doe Trust") so you can easily identify them in the allocation profile.

* Monitor Margin and Buying Power: Allocation profiles will attempt to execute trades based on your rules. However, if one of the sub-accounts doesn't have enough buying power, the trade might be partially filled or rejected for that specific account. Always ensure accounts are adequately funded before placing large allocated trades. * Use Paper Trading First: If you are new to TWS and allocation profiles, test your setup in a paper trading account first. You can set up IBKR paper trading here to practice without risking real capital. * Review Activity Statements: After placing allocated trades, check the activity statements of the individual accounts to ensure the splits occurred as expected. You can export your IBKR activity statements for a detailed view.

FAQ

Can I change the allocation profile after placing an order?

No. Once an order is placed and executed, the allocation is final. If you want to change the allocation, you must place a new order with the updated profile. You can, however, modify the allocation profile for *future* orders.

Do I need to be a professional financial advisor to use Advisor Family Accounts?

No. While the feature is designed for professional advisors, Interactive Brokers allows any primary account holder to link family accounts (such as accounts for children or trusts) and use the allocation features. You do not need a Series 65 or other professional license to use this functionality for personal family management.

Can I allocate trades across different currency accounts?

Yes, but be careful. If you allocate a trade across accounts that hold different base currencies, IBKR will handle the currency conversion automatically. However, this may incur FX fees. It is generally best to allocate trades across accounts that share the same base currency to avoid unexpected conversion costs.

What happens if one sub-account is frozen or restricted?

If a sub-account is frozen, restricted, or lacks sufficient buying power, the allocation profile will fail for that specific account. IBKR will typically attempt to allocate the trade to the remaining active accounts, but the overall trade execution may be impacted. You will receive a notification regarding the partial failure.

Is there a limit to how many accounts I can link?

Interactive Brokers does not publish a strict public limit on the number of accounts you can link in an Advisor Family Account, but practical limits apply based on your relationship with IBKR. For standard retail family use, you can easily link 5-10 accounts without issue. For large institutional setups, you should contact IBKR support directly.

Risk Warning

Managing multiple accounts introduces operational risks, such as partial fills or margin constraints across sub-accounts. Always ensure accounts are adequately funded before placing large allocated trades. This is not financial advice.
