How to name beneficiaries and fund a trust at M1

Beneficiaries are managed online or by mail. Trust paperwork is taken online

There are two ways to keep your M1 investment accounts out of probate: adding beneficiary designations and retitling eligible accounts into a revocable living trust. Which approach works best depends on the account type and your overall estate plan.

With 12 product types, M1 offers a range of transfer options. Some investment accounts support Transfer on Death (TOD) designations, others can be retitled into a trust, and some require probate if no beneficiary is designated. The sections below break down each step.

Beneficiary form at M1

M1 Beneficiary Form and IRA Beneficiary Form (for IRAs).

Open the form →
M1 High-Yield Cash AccountM1 High-Yield Savings Account
1
Log in to M1 on the web and open Profile > Beneficiaries (the M1 mobile app does not support beneficiary management; use a desktop browser or a mobile browser)
2
Click "Add Beneficiary"
3
Configure beneficiary designations:
  • Enter each beneficiary's information, including Social Security Number — M1 requires an SSN for every beneficiary
  • If listing more than one, assign a percentage to each and mark them Primary or Contingent; totals must equal 100% using whole numbers only (e.g., 50/50 or 33/33/34)
  • The online tool applies the same beneficiaries to every eligible M1 account. To set different beneficiaries per account, or to name a trust, use the M1 Beneficiary Form instead
4
Click Save and review the designations listed under Profile > Beneficiaries — name, relationship, percentage share, and primary or contingent all display there
5
Designations are not effective until accepted by M1; M1 notifies the account holder once the update is processed

Required Documents

  • Beneficiary's Social Security number (for every beneficiary)
  • Beneficiary's name, date of birth and relationship (on the M1 Beneficiary Form or the IRA Beneficiary Form)
  • Trust legal name and Tax ID (for a trust)

What M1 says about beneficiaries and trusts

Each section is M1's own statement, with the document it comes from numbered under Sources.

Which accounts take a beneficiary6

Investment account

Individual and joint brokerage accounts take beneficiaries online, where the tool sets one shared set of beneficiaries across every eligible account. Account-specific designations take the M1 Beneficiary Form.1, 2

Payable-on-death account

High-Yield Cash and High-Yield Savings accounts are covered by the same online tool and share its one set of beneficiaries.1

IRA

Traditional, Roth and SEP IRAs take beneficiaries online through the shared tool, or on the IRA Beneficiary Form.1, 3

Crypto account

Crypto accounts (offered by Bakkt) cannot carry beneficiary designations.1

Trust account

Trust accounts cannot carry beneficiary designations.1

Custodial account (UTMA/UGMA)

Custodial accounts cannot carry beneficiary designations.1

Who can be named1

A trust

A trust can be named as beneficiary only through the M1 Beneficiary Form or the IRA Beneficiary Form, with the trust's legal name and Tax ID; the online tool does not take a trust.2, 3

How many beneficiaries, and how shares are split

All accounts

When more than one beneficiary is listed, each is assigned a percentage and marked primary or contingent. Percentages must be whole numbers and total 100% (for example 50/50 or 33/33/34).1

Up to 3 primary and 3 contingent beneficiaries per account when using the M1 Beneficiary Form.2

What M1's agreement says about beneficiaries3

When a designation takes effect

Beneficiary changes are not effective until accepted by M1. M1 notifies the account holder once the update is processed.1

Changing or revoking a designation

A new designation automatically voids the previous one for that account.1

Online access

The M1 mobile app does not support beneficiary management; the web platform or a mobile browser is used. The mobile app does support adding a Trusted Contact, which is a different designation.1

Which accounts a trust can hold2

Trust account

M1 supports U.S. domestic revocable and irrevocable trusts as a distinct account type. Foreign and testamentary trusts are not supported.4

The trust must be in good legal standing in the U.S., authorized to invest in stocks, and carry a valid EIN. The minimum initial account value is $5,000.4

Investment account

For an existing individual or joint brokerage account, the documented path into a trust is opening a Trust account and moving the assets; M1 Client Success coordinates it through the in-app Messenger or by email.4

What M1 says about trust accounts4

Whether a new account is opened

An M1 Trust account "is not a way to create a trust": the trust must already exist, and M1 does not create or draft trusts. An active M1 account in the applicant's own name is required before M1 will accept a Trust account application.4

The trust's tax identification number

The trust must carry a valid EIN; a trust operating under the grantor's SSN is not eligible.4

Review of the trust document

M1 reviews the submission within 7 to 10 business days and may request additional documents by email during review. Once approved, the Trust account appears in the M1 dashboard and can be funded.4

Online access

Only one external connection, a bank account or an M1 Earn account, may be linked to a trust account.4

Not in M1's published guidance1

  • Retitling of an existing brokerage account into a trust, for investment accounts
