Common confusion points

Where do I file this form?

The instructions state not to file Form 5305-S with the IRS.

Keep it with your records.

What is the required minimum distribution (RMD) calculation?

If the beneficiary is the surviving spouse, divide the account value by the joint and last survivor table number; otherwise, use the uniform lifetime table.

Check Article IV, paragraph 5 for details on how to determine this.

When must all my money be distributed?

The remaining interest must be distributed by the end of the calendar year containing the fifth anniversary of the participant’s death.

Confirm the date aligns with your required beginning date.

What is a 'transfer SIMPLE IRA'?

It is a SIMPLE IRA that was not the original recipient of contributions under any SIMPLE IRA plan.

Ensure this classification matches how you are establishing the account.

Who must sign this form?

Both the participant and the custodian must execute the agreement, and a witness signature may be required.

Check if your specific situation requires witnessing.

What is the difference between 5305-S and 5305-SA?

Form 5305-S is the model custodial account agreement; Form 5305-SA is the specific revision currently on file (Rev. April 2017).

Use 5305-SA to ensure you are using the correct version.
