The leading “pass-through” forms are limited partnerships, LLCs, LLPs, S corps, sole proprietorships and general partnerships. You have a lot of power over whether or not your entity is treated as a pass-through for federal tax purposes.
If you have a partnership of any type or a limited liability company, it is possible to choose if your business functions as a corporation or partnership for tax purposes. This is called the “check-the-box” system by tax and business advisors. You can qualify to have it treated as a pass-through by choosing S corp. status if your entity is incorporated or if you elect to be treated as a corporation.
This decision is binding. This means if you select one entity one year and a different one the next, you will have to pay the taxes as though last year’s entity was sold and use those profits towards this year.
