Can I make a check-the-box election on my Canadian corporation before I move to the US?

For most Canadian corporations the answer is no, and the reason is eligibility rather than merit. The US rules put entities formed in Canada as a “Corporation” or a “Company” on a fixed list of things that are always corporations for US tax purposes. An entity on that list isn’t an eligible entity, so Form 8832 simply doesn’t apply to it. The main Canadian exception is an unlimited liability company.

Why can’t I just file Form 8832 for my Canadian corporation?

Because the election is only open to an “eligible entity”, and your company probably isn’t one. The regulation defines that term by exclusion: an entity already classified as a corporation under paragraph (b)(8) of the foreign-entity rules is carved out of it. Paragraph (b)(8) is the per-country table of foreign entities that are always corporations, and Canadian corporations sit on that table. So there is no classification to elect. Filing the form anyway doesn’t change the answer.

“A business entity that is not classified as a corporation under 301.7701-2(b) (1), (3), (4), (5), (6), (7), or (8) (an eligible entity) can elect its classification for federal tax purposes as provided in this section.” Treas. Reg. 301.7701-3(a)

The relevant line in the table is short. Treas. Reg. 301.7701-2(b)(8)(i) reads, in full: “Canada, Corporation and Company.” A company incorporated federally under the CBCA, or provincially in Ontario, British Columbia, Alberta or anywhere else, is classified as a corporation by the regulation itself.

This trips people up because the same election is genuinely available, and genuinely useful, on a US LLC. An LLC is an eligible entity. A Canadian corporation isn’t.

Which Canadian companies actually can check the box?

Unlimited liability companies, and that’s essentially the entire list. The regulation carves them out of the always-a-corporation table, which puts them back inside the definition of an eligible entity and makes Form 8832 available. The carve-out names the Nova Scotia ULC and then describes a wider class in a parenthetical, and the parenthetical is the part that matters.

“The following entities will not be treated as corporations under paragraph (b)(8)(i) of this section: (1) With regard to Canada, a Nova Scotia Unlimited Liability Company (or any other company or corporation all of whose owners have unlimited liability pursuant to federal or provincial law).” Treas. Reg. 301.7701-2(b)(8)(ii)(A)(1)

Read that parenthetical closely. It’s wider than the Nova Scotia reference suggests, because it reaches any Canadian company where all of the owners have unlimited liability, which in practice picks up the Alberta and British Columbia ULCs too. It’s also narrower than people hope. It doesn’t reach a company with one unlimited shareholder among several, and it doesn’t reach an ordinary limited company whose shareholders agreed to accept liability privately. The unlimited liability has to arise “pursuant to federal or provincial law”.

Entity	On the always-a-corporation table?	Form 8832 available?
Canadian corporation (CBCA, OBCA, provincial equivalents)	Yes, as “Corporation”	No
Canadian company limited by shares	Yes, as “Company”	No
Nova Scotia ULC	No, carved out by (b)(8)(ii)(A)(1)	Yes
Alberta or BC ULC (all owners unlimited by statute)	No, same carve-out	Yes
US LLC owned by a Canadian	Never on the foreign table	Yes

If my company is a ULC, when does the election have to be filed?

The effective date you write on the form is bounded on both sides of the day you file it, and the backward bound is short. You can reach 75 days into the past and 12 months into the future. Ask for an earlier date than that and the regulation doesn’t reject the form, it quietly gives you the 75th day instead. That single number usually decides whether pre-move planning is still available, because the date most people want is the day before US residency began.

“can not be more than 75 days prior to the date on which the election is filed and can not be more than 12 months after the date on which the election is filed” Treas. Reg. 301.7701-3(c)

There’s a lock on the other side as well. The same paragraph provides that an entity which elects “cannot change its classification by election again during the sixty months succeeding the effective date of the election.” The regulation adds that the Commissioner may permit a change inside those sixty months where more than fifty percent of the ownership interests are held by people who didn’t own the entity when the earlier election took effect. That’s a discretionary permission rather than an entitlement, so it isn’t something to build a plan on.

What do I do instead if my corporation can’t elect?

You plan around the corporation itself. Once you become a US person, a Canadian corporation you control is a controlled foreign corporation, and the live questions become whether you have a US information-return obligation on it, how its income reaches your US return, and what happens to the Canadian corporate tax you’ve already paid. Those get answered at the corporate level. An entity election that was never available to you can’t help with any of them.

• What happens to a Canadian corporation when you move, which covers the corporate-residence and CFC side
• Whether to wind up the corporation or keep it, which is the decision most of these files actually turn on
• Whether the move creates a Form 5471 obligation, which is the filing people miss

The route people reach for most often is closing the company. That carries a real Canadian tax cost and is a decision in its own right, so it’s worth reading those three together. The answer usually turns on whether the company still runs a real business.

What should I do next?

Two steps, in order. Pull the incorporation document and establish what the company actually is, because the words “Corporation” or “Company” on its face settle the question before any planning begins. Then, if it turns out to be a ULC, fix the date you want the election to bite and count 75 days forward from it. That date, and not anything printed on the form, is your real filing deadline.
