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 per-country list of entities treated as corporations for US tax purposes. An entity on that list isn’t an eligible entity, so Form 8832 doesn’t apply to it. Unlimited liability companies are carved out of the list, and for a single-owner ULC the useful answer is usually that no election is needed at all, though a disregarded ULC still brings a Form 8858 with it.

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. Treas. Reg. 301.7701-3(a) 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 a per-country table of foreign entities treated as corporations, and Canadian corporations sit on that table. So there’s no classification left to elect.

“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)

That table runs to roughly eighty jurisdictions, and the Canadian entry lists “Corporation” and “Company”. Its lead-in matters more than its length, because the list isn’t unconditional.

“Except as provided in paragraphs (b)(8)(ii) and (d) of this section, the following business entities formed in the following jurisdictions:” Treas. Reg. 301.7701-2(b)(8)(i)

Two carve-outs, then. Paragraph (b)(8)(ii) is the one that reaches Canadian companies and is the subject of the next section. Paragraph (d) is a grandfather rule this page doesn’t work through.

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 among the Canadian corporate forms that’s essentially the entire list. Treas. Reg. 301.7701-2(b)(8)(ii)(A)(1) carves them out of the table, which puts them back inside the definition of an eligible entity. The carve-out names the Nova Scotia ULC and then describes a wider class in a parenthetical, and the parenthetical is the part that does the work. Whether a particular Alberta or British Columbia company qualifies is a question about that province’s own statute, and this page doesn’t answer it.

“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)

It reaches any Canadian company where all of the owners have unlimited liability under federal or provincial law, so it isn’t confined to Nova Scotia. 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 took on liability by private agreement, because the liability has to arise “pursuant to federal or provincial law”.

If my ULC is eligible to elect, does it need to?

Usually it doesn’t need to elect, and that isn’t the same as having nothing to file. A foreign eligible entity with a single owner who doesn’t have limited liability is disregarded by default, so where a province’s statute does leave a ULC’s owners carrying unlimited liability, a single-owner ULC reaches disregarded treatment without a Form 8832. What arrives instead is Form 8858: a US person who is directly the tax owner of a foreign disregarded entity is a Category 1 filer, and the form goes in with the income tax return.

“Except as provided in paragraph (b)(3) of this section, unless the entity elects otherwise, a foreign eligible entity is … (C) Disregarded as an entity separate from its owner if it has a single owner that does not have limited liability.” Treas. Reg. 301.7701-3(b)(2)(i)

Now note what the default does for someone who has never had a US filing obligation. Where a foreign eligible entity’s classification has never been relevant, the regulation settles it under those default rules at the moment it first becomes relevant, which for most people is the year they become a US person.

“If the classification of a foreign eligible entity has never been relevant (as defined in paragraph (d)(1) of this section), then the entity’s classification will initially be determined pursuant to the provisions of paragraph (b)(2) of this section when the classification of the entity first becomes relevant.” Treas. Reg. 301.7701-3(d)(2)

Disregarded is a classification, not an exemption from filing. Once the ULC is a foreign disregarded entity and you are a US person who is directly its tax owner, the Instructions for Form 8858 put you in Category 1.

“Category 1 filer. A U.S. person that is directly a tax owner of an FDE or operates an FB at any time during the U.S. person’s tax year or annual accounting period. Complete the entire Form 8858, including the separate Schedule M (Form 8858), Transactions Between Foreign Disregarded Entity (FDE) or Foreign Branch (FB) and the Filer or Other Related Entities.” IRS Instructions for Form 8858

The same instructions define an FDE as an entity that is not created or organized in the United States and that is disregarded as an entity separate from its owner under 301.7701-2 and 301.7701-3, which is what the default rules above produce, and they put the form in with the income tax return it accompanies. A multi-owner ULC sits outside Category 1, because a partnership isn’t disregarded, and what it files instead is a question this page doesn’t work through.

The election a ULC is eligible to make is mostly the one it doesn’t want. Filing Form 8832 buys association treatment, which means corporation, the opposite of what most people arrive asking for. Two or more owners without limited liability default to a partnership rather than a disregarded entity, and disregarded treatment isn’t reachable for a multi-owner entity in any case.

One qualifier on how limited liability gets decided for those default rules, and the regulation scopes it to them. It does not travel to the carve-out in 301.7701-2(b)(8)(ii)(A)(1), which runs on the different phrase “all of whose owners have unlimited liability pursuant to federal or provincial law” and has no organizational-documents limb.

“For purposes of paragraph (b)(2)(i) of this section, a member of a foreign eligible entity has limited liability if the member has no personal liability for the debts of or claims against the entity by reason of being a member. This determination is based solely on the statute or law pursuant to which the entity is organized, except that if the underlying statute or law allows the entity to specify in its organizational documents whether the members will have limited liability, the organizational documents may also be relevant.” Treas. Reg. 301.7701-3(b)(2)(ii)

Entity	On the per-country table?	Default US classification	Form 8832
Canadian corporation (CBCA, OBCA and provincial equivalents)	Yes, as “Corporation”	Corporation	Not available
Canadian company limited by shares	Yes, as “Company”	Corporation	Not available
Nova Scotia ULC, single owner	No, carved out by (b)(8)(ii)(A)(1)	Disregarded	Available, but it buys corporation treatment
ULC with two or more owners	No, same carve-out	Partnership	Available, same effect
US LLC owned by a Canadian	Never on the foreign table	Turns on the number of owners	Available

When does the 75-day window actually matter?

When you actually file an election, rather than accepting whatever the default gives you. The effective date you write on Form 8832 is bounded on both sides of the day you file it: 75 days back, 12 months forward, and those bounds reach every election filed under Treas. Reg. 301.7701-3(c)(1)(i). Ask for an earlier date than that and the regulation doesn’t reject the form, it quietly gives you the 75th day instead.

“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)(1)(iii)

There’s a lock on the other side, and it’s narrower than it usually gets described, because paragraph (c)(1)(iv) narrows “change” for its own purposes in a way the bound above does not. It bites on an election to change classification, and the same paragraph says an election by a newly formed entity effective on its formation date isn’t a change for this purpose. Where it does apply, the Commissioner’s escape hatch turns on two dates rather than one, and it’s a discretionary permission rather than an entitlement.

“If an eligible entity makes an election under paragraph (c)(1)(i) of this section to change its classification … the entity cannot change its classification by election again during the sixty months succeeding the effective date of the election. However, the Commissioner may permit the entity to change its classification by election within the sixty months if more than fifty percent of the ownership interests in the entity as of the effective date of the subsequent election are owned by persons that did not own any interests in the entity on the filing date or on the effective date of the entity’s prior election. An election by a newly formed eligible entity that is effective on the date of formation is not considered a change for purposes of this paragraph (c)(1)(iv).” Treas. Reg. 301.7701-3(c)(1)(iv)

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 can be 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.

• 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

What does this page not settle?

Three things, named rather than left implied. It doesn’t establish that any particular Alberta or British Columbia company has unlimited-liability owners, because no provincial statute is cited here. It doesn’t work through the grandfather in Treas. Reg. 301.7701-2(d), the controlled-foreign-corporation tests, or any Canadian tax consequence of the entity’s US classification. And it makes no claim about the US treatment of a ULC that has already had a US filing history, where the classification was relevant before you arrived.

What should I do next?

Two steps, in order. Pull the incorporation document and establish what the company actually is, because the words on its face settle eligibility before any planning begins. Then, if it turns out to be a ULC, work out what the default already gives you before you reach for a form, because for a single owner the default is usually the treatment people are trying to buy. The 75-day count only starts mattering once you’ve decided you want something other than the default. Whichever way that lands, a disregarded ULC still puts a Form 8858 on your return.
