General Instructions
Section references are to the Internal Revenue Code unless
otherwise noted.

Purpose of Form
Use Schedule B-1 (Form 1065) to provide the information
applicable to certain entities, individuals, and estates that
own, directly or indirectly, an interest of 50% or more in the
profit, loss, or capital of the partnership.

Who Must File
Schedule B-1 (Form 1065) must be filed by all partnerships
that answer “Yes” to question 3a or question 3b on Schedule
B of Form 1065. Attach Schedule B-1 to Form 1065.

Specific Instructions
Part I
Complete Part I if the partnership answered “Yes” to Form
1065, Schedule B, question 3a. List each corporation,
partnership, trust, or tax-exempt organization owning, directly
or indirectly, an interest of 50% or more in the profit, loss, or
capital of the partnership at the end of the tax year. Enter the
name, EIN, type of entity (corporation, partnership, trust, or
tax-exempt organization), country of organization, and the
maximum percentage interests owned, directly or indirectly,
in the profit, loss, or capital of the partnership. For an
affiliated group filing a consolidated tax return, list the parent
corporation rather than the subsidiary members. List the
entity owner of a disregarded entity rather than the
disregarded entity. If the owner of a disregarded entity is an
individual rather than an entity, list the individual in Part II. In
the case of a tax-exempt organization, enter “tax-exempt
organization” in column (iii).
Example 1. Corporation A owns, directly, an interest of 50%
in the profit, loss, or capital of Partnership B. Corporation A
also owns, directly, an interest of 15% in the profit, loss, or
capital of Partnership C. Partnership B owns, directly, an

interest of 70% in the profit, loss, or capital of Partnership C.
Therefore, Corporation A owns, directly or indirectly, an
interest of 50% in the profit, loss, or capital of Partnership C
(15% directly and 35% indirectly through Partnership B). On
Partnership C’s Form 1065, it must answer “Yes” to question
3a of Schedule B. Partnership C must also complete Part I of
Schedule B-1. In Part I, Partnership C must identify
Corporation A, which includes entering “50%” in column (v)
(its maximum percentage owned). It also must identify
Partnership B, and enter “70%” in column (v).

Part II
Complete Part II if the partnership answered “Yes” to Form
1065, Schedule B, question 3b. List each individual or estate
owning, directly or indirectly, an interest of 50% or more in
the profit, loss, or capital of the partnership at the end of the
tax year. Enter the name, social security or employer
identification number, country of citizenship (for an estate,
the citizenship of the decedent), and the maximum
percentage interests owned, directly or indirectly, in the
profit, loss, or capital of the partnership.
Example 2. A owns, directly, 50% of the profit, loss, or
capital of Partnership X. B, the daughter of A, does not own,
directly, any interest in X and does not own, indirectly, any
interest in X through any entity (corporation, partnership,
trust, or estate). Because family attribution rules apply only
when an individual (in this example, B) owns a direct interest
in the partnership or an indirect interest through another
entity, A’s interest in Partnership X is not attributable to B.
On Partnership X’s Form 1065, it must answer “Yes” to
question 3b of Schedule B. Partnership X must also
complete Part II of Schedule B-1. In Part II, Partnership X
must identify A, which includes entering “50%” in column (iv).
Partnership X will not identify B in Part II.
