Form 8832: changing an entity's federal tax classification
Form 8832 is the mechanism behind the US "check-the-box" system, which lets many business entities choose how they are taxed rather than being locked into one treatment by their legal form. It is most often met by LLC owners deciding whether their LLC should be taxed as a corporation. This guide explains the default classifications the form departs from, what electing does, and the timing and limitation rules that make the election a considered step.
The default classifications
Every eligible entity has a default federal tax classification, and much of the time the default is exactly right, so no election is needed. The defaults are:
- A single-member LLC is a disregarded entity — ignored for federal tax, with its activity reported on the owner's return, as covered in single-member LLC taxation.
- A multi-member LLC is a partnership, filing Form 1065, per single- versus multi-member treatment.
- A newly formed domestic corporation is a C corporation.
Form 8832 exists for the cases where the owner wants to depart from that default.
What the election does
Filing Form 8832 lets an eligible entity elect to be taxed as a corporation (an association), or in some cases change between classifications. The central point is that it changes only the tax classification: an LLC that elects corporate taxation is still an LLC under state law, with the same owners, operating agreement, and liability protection. Only how the IRS taxes it changes. The most common reason an LLC owner considers this is to access corporate treatment — often as a stepping-stone to S corporation status — a decision that should be weighed against the pass-through baseline set out in LLC versus C corporation.

The election has a flexible effective date but a firm brake on changing your mind. The effective date chosen on the form can be up to 75 days before the filing date or up to 12 months after it, giving some room to make the election apply to a chosen point. Against that flexibility sits the 60-month limitation: once an entity changes its classification by election, it generally cannot elect to change again for 60 months. The rule is there precisely to stop entities toggling their tax treatment year to year, which means the choice is one to make deliberately rather than reverse casually.
Form 8832 and Form 2553
A frequent source of confusion is the relationship with the S election. Form 8832 elects corporate taxation; Form 2553 elects S corporation status specifically. An LLC that wants to be an S corporation does not usually need to file both: under the instructions, an eligible entity that files a timely Form 2553 is treated as having also made the deemed election to be a corporation, so Form 2553 on its own achieves the S outcome. Form 8832 is the right form when the goal is C corporation treatment, or a classification change that is not about S status. Knowing which form to file is half the task, because filing the wrong one — or both unnecessarily — creates avoidable confusion in the entity's record.

Questions people also ask
What is Form 8832 for?
Form 8832, the Entity Classification Election, lets an eligible business entity choose how it is taxed federally — this is the "check-the-box" election. An LLC, for example, can use it to elect to be taxed as a corporation instead of under its default treatment. It changes the tax classification only; it does not change what the entity is under state law, which remains an LLC or whatever it was formed as.
What happens if I do not file Form 8832?
The entity keeps its default classification. A single-member LLC is by default a disregarded entity, taxed as part of its owner. A multi-member LLC is by default a partnership. A newly formed domestic corporation is a C corporation by default. Many businesses never need Form 8832 because the default suits them; it is only needed to depart from the default.
How does Form 8832 relate to electing S corporation status?
They are different elections. Form 8832 elects corporate taxation; Form 2553 elects S corporation status specifically. An entity that wants S treatment does not usually need both — under the instructions, an eligible entity that files Form 2553 on time is treated as having also elected to be a corporation, so Form 2553 alone can achieve the S result. Form 8832 is used to elect C corporation treatment, or to change classification more generally.
