Determining the Name Control for Form 1041

In 2023 the IRS changed the name control requirements for certain 1041 filers. Just because you were able to e-file a trust's return using a certain name control in prior years doesn't necessarily mean that same name control will be accepted on new filings.

How do I know what name control to use?

For most estates and trusts, there are three ways to find the correct name control for e-filing:

• On the original IRS notice CP 575B, which the estate or trust received when their EIN was assigned
• By computing the entity's name control following the rules in Pub. 4164
• Or by contacting the IRS Business Specialty Tax Line at 1-800-829-4933

To find the name control on CP 575B:

The name control appears on a tear-off tab attached to the notice.

If you no longer have that portion of the form, reference the top of the second page. You should see a string similar to the following example:

(IRS USE ONLY) 575B 10-31- 2018 NAME B 9999999999 SS-4

The name control is the four letters directly following the date in this string. In this example, the name control is "NAME".
