Getting a separate EIN for a specific series is a vital step for your legal “wall.” It allows the series to open its own bank account, hire its own employees, and file its own tax reports without tangling up the Parent Trust.

​Here is the process for a Wyoming Statutory Trust Series as of 2026.

​1. Timing: The “Order of Operations”

​Do not apply for a Series EIN until:

  1. ​The Master Trust is filed with Wyoming.
  2. ​You have already signed the internal Certificate of Designation (the “birth certificate” for that series).
  3. ​The Parent Trust already has its own EIN.

​2. How to Apply (The IRS Path)

​You can apply online at IRS.gov, but you must be careful with the naming conventions to ensure the IRS recognizes it as a sub-unit.

A. The Legal Name (Line 1)

​You must use the “Parent Name + Series Name” format.

  • Example: “Apex Statutory Trust – Series 01”
  • Why? This tells the IRS and the bank exactly which “bucket” this tax ID belongs to.

B. The Responsible Party (Line 7)

​This is usually the person who signed the Master Trust Agreement (the Benefactor/Settlor) or the Master Trustee. They must have a valid SSN or ITIN.

C. Type of Entity (Line 9)

  • ​Select “Trust.”
  • ​The IRS may ask if it is a “Grantor Trust” or “Other.” If you are raising money from investors (as we discussed), you will likely be checking “Other” (specifically a “Complex Trust” or “Partnership” depending on your tax advisor’s strategy for that series).

​3. Critical: The “Separate Records” Rule

​Once you get the EIN, you must use it to open a dedicated bank account.

​[!CAUTION]

If you use the Parent Trust’s EIN for Series A’s bank account, you are “commingling” the entities. In a lawsuit, a judge could decide that Series A is not actually separate, and your liability shield could collapse.

​Summary of the “Tax ID Hierarchy”

EntityHas its own EIN?Why?
Parent TrustYesTo hold master assets and sign general contracts.
Series 01YesTo raise funds and own specific assets (Real Estate, etc.).
Series 02YesTo keep its risks separate from Series 01.

Your Next Step

​Now that you have the paperwork and the tax ID strategy, the final piece of the “Legality” puzzle is the Form D Filing. Since you are raising funds, the SEC requires this notification within 15 days of taking your first dollar.
