Interactive Brokers Joint Accounts guide

Joint accounts let two or more people hold investments together, which can suit couples and family members building a long-term portfolio. Availability, ownership structures and paperwork vary by broker and by the country you live in, so this guide focuses on what to check with Interactive Brokers directly rather than assuming any specific feature applies to you. Treat everything here as a verification checklist and confirm the details in the broker's current account documents before you apply.

What a joint account is and why the structure matters

A joint brokerage account is owned by more than one person, and the legal ownership structure decides what happens to the assets if one holder dies, divorces or becomes incapacitated. Common structures in some jurisdictions include joint tenants with rights of survivorship and tenants in common, but the options available depend on local law and on what the broker supports for your residency. Before opening a joint account with Interactive Brokers, confirm which ownership types are offered in your country, because the structure affects estate planning, tax reporting and who can give instructions on the account. If you are unsure which structure fits your situation, speak to a qualified legal or tax adviser rather than relying on general guides.

Confirm which joint ownership structures Interactive Brokers offers for your country of residence.
Check who is legally allowed to place trades, withdraw funds and close the account.
Ask how the account is treated if one holder dies or the relationship between holders changes.
Verify how the account is reported for tax purposes in your jurisdiction.

A verification checklist before applying

Do not assume a joint account is available to you until you have confirmed it in the broker's current documentation for your region. Application requirements for joint accounts are usually heavier than for individual accounts because every holder normally needs to pass identity and residency checks. Work through the checklist below using Interactive Brokers' official account opening pages and disclosures, and keep copies of what you read, since terms can change. If your residency, citizenship or tax status differs between the two holders, ask the broker how that combination is handled before you start the application.

Verify that joint accounts are offered to residents of your country and note any restrictions.
List the identity, address and tax documents required from every account holder.
Confirm minimum deposit rules, account fees and currency options in the current fee schedule.
Check whether both holders receive statements, tax forms and platform access.

Costs, ongoing administration and where to research next

Joint accounts carry the same trading and account costs as other accounts, so review the current commission schedule, currency conversion charges and any inactivity or data fees before funding. Also plan the practical side: agree with your co-holder how decisions are made, who monitors statements and how you will handle disagreements about the portfolio. You can estimate likely trading costs with the Brokerage fee calculator (/tools/brokerage-fee-calculator), compare your requirements against other brokers through Find my broker (/find-my-broker), and read related guides at the Long-term investing hub (/invest-long-term). Whatever you conclude, confirm final figures against the broker's own published fee schedule on the day you apply.

Review the current commission and fee schedule directly on the broker's site before funding.
Agree in writing with your co-holder how contributions, withdrawals and decisions are handled.
Use the Brokerage fee calculator to estimate ongoing costs for your expected activity.
Revisit the account terms periodically, since fees and eligibility rules can change.
