Form 1065 Schedule B-1 – Fillable PDF Download

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.

WAT BETREFT

Federale belastingformulieren

Form 1065 Schedule B-1 is een van de federale belastingformulieren die worden gebruikt voor het rapporteren en indienen van federale inkomstenbelastingen bij de Internal Revenue Service (IRS) in de Verenigde Staten. Deze formulieren worden door individuen, bedrijven en organisaties gebruikt om hun inkomsten, inhoudingen en andere relevante informatie te rapporteren die nodig is voor het berekenen van hun federale belastingplicht.

Het meest gebruikte federale belastingformulier is het Formulier 1040, dat door individuele belastingbetalers wordt gebruikt om hun personenbelasting aan te geven. Andere veelgebruikte formulieren zijn het Formulier 1065 voor partnerschappen, Formulier 1120 voor bedrijven, en Formulier 990 voor belastingvrijgestelde organisaties.

Federale belastingformulieren vereisen doorgaans dat belastingbetalers verschillende bronnen van inkomsten rapporteren, zoals lonen, salarissen en fooien, evenals inkomsten uit investeringen, huurwoningen en andere bronnen. Met de formulieren kunnen belastingbetalers ook aftrekposten en tegoeden claimen voor verschillende uitgaven, zoals liefdadigheidsbijdragen, hypotheekrente en zorgkosten.

Het is belangrijk om federale belastingformulieren nauwkeurig en op tijd in te dienen, omdat het niet doen hiervan kan leiden tot boetes en rentelasten van de IRS.
