S corporation owner in Canada: ineligible election and relief

Does moving to Canada end my S election?

Moving to Canada does not, by itself, end an S election. Becoming a nonresident alien shareholder does. A nonresident alien is someone who is neither a US citizen nor a US resident for tax purposes, and an S corporation cannot have one as a shareholder, wherever the person lives or whatever other citizenship the person holds (IRS: S corporations; 26 CFR 1.1361-1(g)). The election then ends for the whole company on the date the owner becomes one, unless relief applies.

A US citizen living in Canada can remain an eligible shareholder; green card and treaty cases need their own status review. See moving across the border with a company for that review and the decision to keep, pay out or wind up the company.

Which owners make an S election ineligible?

Only individuals who are US citizens or US residents, estates, certain trusts and certain exempt organizations can own S corporation shares. One ineligible shareholder can defeat S status for the whole corporation, and no minimum shareholding makes a nonresident alien acceptable (Form 2553 instructions).

A spouse in Canada can make the company ineligible even when only the US spouse holds the shares. If a US shareholder's spouse is a nonresident alien with a current ownership interest in the stock under an applicable law, such as a community property law or a foreign country's law, the corporation fails the shareholder test from the date the spouse acquires it (26 CFR 1.1361-1(g)(1)). The regulation names section 1362(f) relief for this case, and in its example a section 6013(g) election already in effect cures it: both spouses sign a statement attached to a joint return for the first year it covers, made within 3 years after filing the original return or 2 years after paying that year's tax, whichever is later (26 CFR 1.6013-6(a)(4)). It does not say whether a later election repairs an earlier year. See married to a nonresident for what the election changes. Whether a particular Canadian family property law gives a spouse that interest is a legal question this page does not decide.

A nonresident alien who is only a potential current beneficiary of an electing small business trust does not defeat eligibility. The trustee must make that election within 2 months and 16 days after the shares reach the trust, and no interest in the trust may have been bought. One treated as the owner of a trust that holds shares is treated as the shareholder, and a foreign trust cannot hold shares (Form 2553 instructions; 26 U.S.C. 1361(c)(2) and (e); 26 CFR 1.1361-1(m)(2)).

On what date did my S election end, or was it never valid?

A valid S election ends on the date an event makes the corporation ineligible. The date is the shareholder's status change or stock acquisition, not the date someone discovers the problem or receives an IRS notice (26 CFR 1.1362-2(b)).

Reconstruct who held shares on each date and each owner's US tax status on those dates, then compare them with the intended effective date on Form 2553.

A resident alien who leaves the US becomes a nonresident alien on the residency termination date, not the day of the move: December 31 of the last year the person is a US resident, or an earlier date if the person's tax home and closer connection were abroad for the rest of the year (Publication 519). A green card holder who moves generally stays a resident until that status is formally ended; see leaving the US. For a dual resident who claims treaty nonresident status, the regulations generally treat the person as a US resident for other Code purposes but reserve the S corporation rule, so that case is unsettled (26 CFR 301.7701(b)-7(a)(3) and (4); 26 CFR 1.1361-1(g)(2)).

An LLC needs special care. A timely S election creates a deemed election to be taxed as a corporation only if the LLC meets the other S eligibility requirements on the effective date. Without a separate effective corporate classification election, an LLC whose Form 2553 was invalid from the start may retain its default classification: disregarded with one owner, or a partnership with several. A corporate classification from a valid S election continues after S status ends (26 CFR 301.7701-3(b) and (c)(1)(v)(C)).

Does the IRS acceptance letter mean my election is valid?

An IRS acceptance letter does not cure an ineligible shareholder. Revenue Procedure 2022-19 describes the CP261 notice as an administrative acknowledgment; shareholder eligibility remains a separate legal requirement (sections 2.01 and 2.03(4)).

If the issue is only a late Form 2553 or a missing acknowledgment, see late S corporation election relief.

Which returns apply if the election ended, or an LLC's election never took effect?

A corporation whose S election ended files Form 1120-S for the S period and Form 1120 for the C period; Form 1120-S is not the correct return for a C corporation period (Form 1120-S instructions; Form 1120 instructions). An LLC whose election never took effect stays in its default class unless a separate election made it a corporation, so Form 1120 may not apply at all.

A distribution to a Canadian owner in a C period may be a dividend, so the payer may owe withholding at 30% or a lower treaty rate and Forms 1042 and 1042-S, even for payments made while it believed it was an S corporation (IRS: withholding on payments to nonresident aliens; Form 1042 instructions). The company, as payer, is liable for tax it should have withheld (26 U.S.C. 1461), assessable 3 years after Form 1042 is filed, or at any time if none was (26 U.S.C. 6501(c)(3)). Cash paid after a termination, within the post-termination transition period (the later of one year after the last S corporation day or the final S return's due date (with extensions), or 120 days after a determination that the election ended), first reduces stock basis up to the accumulated adjustments account, unless every shareholder paid elects out (26 U.S.C. 1371(e); 26 U.S.C. 1377(b)).

For a midyear termination, the S part's return is due when the C part's return is due: the 15th day of the fourth month after year-end (the C part's year-end), or six months later with Form 7004, which does not extend the time to pay (26 CFR 1.1362-3(c)(5); Form 1120 instructions). Profit is split between the two parts by days, not by when invoices were issued or paid, unless the company's normal accounting method decides, either by election or because half or more of the shares changed hands by sale or exchange (26 CFR 1.1362-3(b)). The election is a statement filed with the C part's return, with a signed consent from everyone who held shares during the S part or on the first day of the C part, the Canadian owner included (26 CFR 1.1362-6(a)(5) and (b)). On the final Form 1120-S, check the "S election termination" box in item H and attach a statement giving the termination and its date (Form 1120-S instructions).

For the C corporation period, a foreign shareholder holding at least 25% of vote or value, directly or indirectly, at any time in the year can make the corporation a Form 5472 reporting corporation if it has reportable transactions with the owner or persons related to the owner (Form 5472 instructions). See foreign-owned C corporation filing for what counts and the penalties.

A Form 1120-S filed for a C corporation period may still leave a Form 1120 outstanding. The usual late-filing penalty is 5% of the unpaid tax for each month or part of a month, up to 25%; see late filing and payment penalties and correcting a filed business return. The corporation owes the corporate tax for a C period. If it cannot pay, the IRS can assess shareholders who received its assets as transferees where the law makes them liable, within one year after the period for assessing the company ends (26 U.S.C. 6901(a) and (c)(1)).

If a ruling request is pending when a return is filed, the IRS procedure requires notification and a copy of the request or the permitted electronic filing statement; requesting relief does not remove filing obligations (Revenue Procedure 2026-1, section 7.05(2)).

Can an ended or invalid election be rescued?

Section 1362(f) allows discretionary relief for an inadvertently invalid election or inadvertent termination. The corporation must establish inadvertence, take steps to restore eligibility within a reasonable period after discovery, and obtain the required adjustment agreements (Revenue Procedure 2022-19, section 2.02).

A relief request has to show, roughly in this order (26 CFR 1.1362-4(c); Revenue Procedure 2026-1):

1. The failure date, and how and when the problem was discovered.
2. Why the failure was inadvertent, with supporting records.
3. Steps taken within a reasonable period after discovery so that the corporation is a small business corporation again.
4. Corporate and shareholder consents to the required adjustments.
5. A private letter ruling request with the facts, correction steps, legal analysis, required declarations and the applicable user fee.

The IRS user fee for this kind of request is generally US$43,700. With a certification, a reduced fee of US$3,450 applies below US$400,000 of gross income, or US$9,775 below US$10,000,000; certain related persons' income is combined (Revenue Procedure 2026-1, Appendix A). The simplified procedures in Revenue Procedure 2022-19 cover six specified areas; they do not provide a general correction procedure for nonresident alien ownership (section 2.03).

Relief is not permission to keep an ineligible owner indefinitely: the statute requires steps, within a reasonable period after discovery, so that the corporation is a small business corporation again, or to obtain missing consents. Which steps fit depends on who the owner is and how the shares are held, and a share transfer can have its own tax effects in the US and Canada. The IRS decides whether to grant relief, for which period and on what adjustments (26 U.S.C. 1362(f); 26 CFR 1.1362-4(a)).

Relief can reach back to the failure date, treating the company as if its election had been valid or had not ended. Or it can start only when eligibility was restored, leaving the ineligible period taxed as a C corporation period (26 CFR 1.1362-4(f); Revenue Procedure 2022-19, section 2.02(3)).

What must all shareholders agree to if relief is granted?

The corporation and everyone who held shares at any time during the IRS-specified relief period must consent to the adjustments the IRS requires. Former shareholders and the ineligible shareholder are included, so consent from current eligible owners alone is insufficient. Each consent is a written statement agreeing to the adjustments, signed by the shareholder, or for the corporation by a person authorized to sign its Form 1120-S, and giving the signer's name, address, taxpayer number and, for a shareholder, shares held and dates (26 CFR 1.1362-4(e)).

The IRS can require adjustments that protect revenue and treat the ineligible owner as an S shareholder for the period of actual ownership. For a Canadian owner, that can mean reporting a share of past company income on a US return for each year the shares were held (26 CFR 1.1362-4(d); Revenue Procedure 2022-19, section 2.02(3)).

If relief is unavailable, when can I elect S status again?

After termination, a new S election generally cannot take effect before the fifth tax year after the first tax year in which termination took effect unless the IRS consents. Restoring eligible ownership does not automatically revive the old election (Form 1120-S instructions). A corporation that elects again after a C period also faces the built-in gains tax on gain from assets it held when the new election began, for a recognition period of 5 years (26 U.S.C. 1374).

The corporation must qualify for S status again. The IRS can consent to an earlier election: consent tends to be supported when more than half the stock is held by people who owned none on the termination date, and is otherwise ordinarily denied unless the event was outside the control of the corporation and its substantial shareholders and not part of a plan to end the election. The restriction can also reach a successor corporation, so a replacement company does not by itself avoid the waiting period (26 CFR 1.1362-5(a) and (b)).

The statutory waiting period applies to a terminated election (26 U.S.C. 1362(g)). If an owner was ineligible on the first day of the first intended S year, the regulation gives automatic consent to a later election; whether it fits depends on the facts, and it does not correct the original period (26 CFR 1.1362-5(c)(2)).

What changes in Canada if the company is a US C corporation?

US C corporation treatment does not settle the Canadian tax position. A Canadian resident individual generally includes dividends from a nonresident corporation in income (Income Tax Act, section 90), and can be taxed on a controlled foreign affiliate's foreign accrual property income, a category of investment-type income, as it is earned rather than when paid out (section 91). Managing the company from Canada can also make it resident in both countries. The treaty tiebreaker generally treats a corporation as resident where it was created, and subsection 250(5) then deems it nonresident in Canada (CRA: corporate residency; section 250). See Canadian owner of a US corporation: filing in each country for the Canadian filings.

What should I gather before a CPA reviews this?

Records of ownership, US tax status and returns filed, for each affected period:

• Formation documents, stock ledger, share certificates, transfers and shareholder agreements.
• Form 2553, proof of filing, the CP261 acceptance letter and IRS correspondence.
• For an LLC, Form 8832 and any other classification election or relief already obtained.
• Each owner's citizenship, green card history, US presence and residency dates, relevant elections, and treaty positions.
• Company and owner returns in both countries, K-1s, extensions, assessments and notices.
• Accounts for the affected periods, and records of distributions, loans, salary and other payments to each Canadian owner, including any Form W-8BEN.
• A dated account of discovery and correction, plus contact information for former shareholders whose consents may be needed.

Example

A calendar-year US corporation has a valid S election and one eligible owner. On July 1, a Canadian resident who is neither a US citizen nor a US tax resident buys 30% of its shares from the owner. The company earns US$100,000 of profit during the year. These figures are illustrative; no tax is calculated.

Without relief, S status ends on July 1. The corporation reviews a Form 1120-S for January 1 through June 30 and a Form 1120 for July 1 through December 31, both due on the C return's due date. By default the profit is split by days, not by when customers paid: in a 365-day year, 181 days puts about US$49,600 in the S period and about US$50,400 in the C period. All shareholders, the Canadian owner included, could instead consent to use the company's normal accounting method; a 30% change is below the half-or-more change that also forces it. The foreign ownership also calls for a Form 5472 review (termination-year rules).

If the company discovers the ownership problem and restores eligibility within a reasonable period, it may request relief. The IRS decides whether to grant it and what adjustments the company and both shareholders must accept (Revenue Procedure 2022-19, section 2.02). Without relief, the company generally cannot elect S status again for any year before the fifth calendar year after the year of termination unless the IRS consents (Form 1120-S instructions).
