Schedule B-1 (Form 1065) is an IRS attachment used by partnerships to disclose ownership of partnership interests by entities and individuals that own 50% or more of the profit, loss, or capital. Whether you are a general partner, limited partner, or an estate, accurate reporting on this schedule is critical for compliance with IRS Schedule B-1 requirements.

What Is Schedule B-1 (Form 1065)?

Schedule B-1 collects detailed information about owners who hold a significant stake (50% or more) in a partnership. The form asks for the owner’s name, taxpayer identification number, type of entity, and the percentage of ownership. This data helps the IRS track partnership structures and enforce tax rules on large ownership positions.

Who Must Complete Schedule B-1?

Any partnership filing Form 1065 that has an individual, estate, or entity owning 50% +  of the partnership’s profit, loss, or capital.
Foreign partners are also required to be listed if they meet the ownership threshold.
Partnerships that do not have any 50% +  owners can leave Schedule B-1 blank, but the form must still be attached to the return.

ABOUT

Internal Revenue Service (IRS) Forms

Form 1065 Schedule B-1 is one of the official tax forms used in the United States to report income, claim deductions and credits, calculate tax liability, and fulfill other tax-related obligations. The IRS is the federal agency responsible for administering and enforcing the internal revenue laws in the United States.

Here are some examples of Internal Revenue Service forms:

Form 1040: This is the primary individual income tax return form used by most taxpayers. It is used to report various types of income, claim deductions and credits, calculate tax liability, and determine whether a taxpayer owes additional tax or is entitled to a refund.

Form 1099: There are different variations of Form 1099, such as 1099-MISC, 1099-INT, 1099-DIV, etc. These forms are used to report income received by individuals or businesses from various sources other than employment, such as self-employment income, interest income, dividend income, and rental income.

Form W-2: This form is used by employers to report wages paid to employees and the taxes withheld from their pay. Employees use the information on Form W-2 to complete their individual tax returns.

Form 941: Employers use this form to report employment taxes, including federal income tax withheld, Social Security tax, and Medicare tax, for their employees.

Form 1065: This form is used by partnerships to report their income, deductions, and tax liability. Partnerships themselves do not pay income tax; instead, the partners report their share of partnership income on their individual tax returns.

Form 1120: This is the corporate income tax return form used by C corporations to report their income, deductions, and tax liability.

Form 990: This form is used by tax-exempt organizations, such as nonprofits and charities, to report their financial information, activities, and compliance with tax laws.

Form 8862: This form is used by taxpayers who previously claimed the Earned Income Tax Credit (EITC) but had it disallowed, and now want to claim it again.

These are just a few examples of the numerous IRS forms that exist to fulfill various tax-related obligations. The specific forms required for an individual or business depend on their unique circumstances, income sources, and deductions. It's advisable to consult the official website of the Internal Revenue Service (www.irs.gov) or seek professional tax advice to obtain accurate and up-to-date information regarding the specific IRS forms relevant to your tax situation.
