Trust mapping policy
- Every trust type offered in the product is mapped to at least one official reference form or guide PDF.
- Many trust types share baseline administration forms (SS-4, Form 56, Form 1041, and Schedule K-1).
- Specialized trust categories include additional forms (for example Form 5227, Form 709, or foreign-trust forms).
- Mappings are informational and may be condition-based by trust tax status, funding method, and jurisdiction.
