Canadian Partner in a US LLC: Withholding and Returns

Is a multi-owner US LLC a partnership in both countries?

A domestic US LLC with multiple owners is a partnership for federal income tax unless it elects corporate status. Canada generally treats a US LLC as a corporation, even when the US taxes its members as partners. A US limited partnership may instead be a partnership in both countries. IRS: LLC classification; CRA: LLC classification.

The LLC elects US corporate status on Form 8832. All current owners or an authorized officer, manager or member sign; affected former owners also sign a retroactive election. To use an earlier effective date, it generally files within 75 days after that date. IRS: Form 8832.

The CRA compares the entity's rights and obligations under state law and its governing agreement with Canadian business forms. Its published LLC discussion is archived, but its current competent authority guidance still says it treats a US LLC as a taxable corporation. An unusual LLC agreement or a limited partnership needs its own classification review. CRA: partnership classification.

Before using the foreign corporation rules, check where the LLC is actually managed. Central management and control in Canada can make the LLC resident under Canadian domestic law, with its own T2 unless treaty residence makes it nonresident under Income Tax Act section 250(5). If the LLC is resident and transfers property to a non-arm's-length member for less than fair value, section 160 can make the recipient jointly liable for the lesser of the value shortfall and the LLC's tax for the transfer year or earlier; the CRA may assess the recipient at any time. CRA: corporate residency; Income Tax Act: section 250; Income Tax Act: section 160.

Why did the LLC withhold tax when it paid me no cash?

Section 1446 withholding applies to a foreign partner's allocated effectively connected taxable income from a US trade or business, regardless of distributions. It is a payment toward the partner's US tax, not the partner's final tax bill. IRS: foreign partners.

The usual withholding rate is 37% for a noncorporate foreign partner and 21% for a corporate foreign partner; certain income may qualify for a preferential rate. The partnership owes unpaid section 1446 withholding under sections 1446 and 1461. A limited partnership's general partner may also owe that debt under its formation state's law; that personal exposure needs a state-law review. Federal levy or suit generally must start within 10 years after assessment, subject to suspension or extension. The partnership remits the tax, and US law treats that payment for you as a distribution even if you receive no cash. Reconcile it with your cash distributions and capital account; its Canadian treatment may differ. 26 USC 1446; 26 USC 1461; IRS: Form 1065 instructions; 26 USC 6502; IRS: Form 8804 instructions. For withholding adjustments and the partnership's forms, see Foreign partners and withholding.

An eligible individual or corporate partner can sign Form 8804-C for partner-level deductions and give it to the partnership during its tax year, before it files Form 8804. The partnership may use it to reduce withholding. IRS: Form 8804-C instructions.

What do Schedule K-1 and Form 8805 show if their amounts differ?

Schedule K-1 shows your US share of partnership tax items; Form 8805 shows the share used for section 1446 withholding and the tax credit allocated to you. They answer different questions, so their income figures can differ without either form being wrong. IRS: K-1 instructions; IRS: Form 8805 instructions.

Compare the partnership's allocation schedule, K-1, K-3 and Form 8805 before filing. Form 8805's effectively connected amount can differ from total K-1 income, and withholding may reflect allowed adjustments. If tax was withheld but Form 8805 is missing, ask the partnership for it before claiming the credit. Ask it to correct any wrong form; if you must report a K-1 or K-3 item differently, check whether Form 8082 is required. IRS: Form 8805 instructions; IRS: Form 8082 instructions.

The partnership may also withhold on US-source income that is not effectively connected with a US business. That withholding is reported on Form 1042-S and, if you file Form 1040-NR, goes on line 25g rather than the Form 8805 line 25e. IRS: partnership withholding types; IRS: Form 1040-NR instructions.

When do I file Form 1040-NR and claim the withholding?

If the partnership carries on a US trade or business, a nonresident individual partner is treated as carrying it on and generally must file Form 1040-NR, even if a treaty may exempt the income or the partnership withheld tax. Report the taxable US items and attach Form 8805 to claim its withholding on line 25e. IRS: effectively connected income; IRS: Form 1040-NR instructions.

You need a valid US taxpayer identification number to claim a refund; an individual who cannot get a Social Security number may need an ITIN. IRS: foreign partner taxpayer IDs.

For a calendar-year individual with no US employee wages subject to withholding, Form 1040-NR is generally due on the 15th day of the sixth month after year-end. If you had such wages, the general date is the 15th day of the fourth month. These rules come from the latest published Form 1040-NR instructions, which cover the prior return year. If withholding exceeds the final federal tax, the return is also how you request a refund. Other US business income, estimated tax and state returns are covered in Nonresident US business returns.

What goes on my Canadian return if Canada sees the LLC as a corporation?

If the US LLC is a nonresident corporation for Canadian purposes, a K-1 alone does not make its annual profit your Canadian partnership income. Canada generally taxes a Canadian-resident shareholder on a dividend when the LLC distributes it; a controlled foreign affiliate can also create current income from foreign accrual property income, or FAPI, even without cash. Income Tax Act: dividends; Income Tax Act: FAPI.

If you personally receive a foreign dividend, report it in Canadian dollars on T1 line 12100; it does not qualify for the Canadian dividend tax credit. The K-1 profit is not itself the dividend amount. CRA: line 12100.

A distribution is not automatically a dividend: capital returns, redemptions and other transactions can have different rules. For a foreign affiliate's pro rata paid-up-capital reduction that would otherwise be a dividend, Income Tax Act section 90(3) permits a qualifying return-of-capital election by written notice to the CRA by the owner's filing due date for the tax year containing the affiliate year-end; connected owners may need a joint election by the earliest applicable due date. A Canadian shareholder must also convert reportable amounts to Canadian dollars. Income Tax Act: section 90; Income Tax Regulations: subsection 5911(6). For a partnership recognized by Canada, CRA's partnership guidance says partners report their shares, while its foreign tax credit folio addresses currency conversion.

Does the Canada–US treaty remove US tax on my share?

The treaty can limit US tax on a Canadian treaty resident's business profit if the resident has no US permanent establishment. If both countries treat an individual as resident, apply Article IV's individual residence tie-breaker before claiming treaty relief; a dual-resident company follows different Article IV rules. This generally means a fixed place through which the business operates, such as an office; some agents can also create one. Check the partnership's US activities. Treaty relief does not automatically erase section 1446 withholding or the US filing duty, but income proven exempt by treaty is excluded from the partnership's section 1446 withholding base. A treaty claim on Form 1040-NR may also require Form 8833. The classification of the entity and how each country taxes the same amount matter. Canada–US treaty, Articles IV, V and VII; IRS: Form 8804 instructions; IRS: nonresident filing.

For a partnership that Canada also treats as transparent, the partner may be able to invoke the business-profits rule after reviewing the partnership's US activities and permanent establishment. For an LLC that Canada treats as a corporation, Article IV(7) can deny a benefit where the US attributes the profit to you but Canada would not tax it in the same way as if you earned it directly. This needs a transaction-by-transaction treaty review; a K-1 and Canadian residence are not enough. Treaty, Article IV(7).

Can I claim the US tax on my Canadian return?

A Canadian foreign tax credit may be available for eligible US income tax on income reported in Canada, but Form 8805 withholding is not automatically the credit amount. An individual's Canadian return is generally due the following April 30, or June 15 if the individual or spouse carried on a business; tax remains payable by April 30. File using supported eligible US tax. If the final US liability or refund changes, request a Canadian return adjustment and match the tax to the Canadian taxpayer, income type, source and year. Income Tax Act: filing dates; CRA: payment date; CRA: foreign tax credit; CRA: change a return.

An individual generally calculates the federal credit on Form T2209 and, outside Quebec, the provincial or territorial credit on Form T2036. A Quebec resident also files a separate Quebec return and uses Revenu Québec Form TP-772-V for a Quebec foreign tax credit. The US may tax your LLC profit now while Canada taxes a later dividend, leaving no matching Canadian income for the earlier year. The CRA says unused nonbusiness foreign tax cannot be carried to a later year as that type of credit; another deduction may sometimes apply. Eligible unused foreign business tax credit can instead be carried back 3 years or forward 10 years. For a carryback, an individual files Form T1-ADJ, or a corporation files T2 Schedule 21 Part 4, by the filing due date for the year the unused credit arose. Income Tax Act: section 126; CRA: foreign tax credit folio; Revenu Québec: foreign tax credit. The full credit calculation is covered in Foreign income on a Canadian return.

Do I report the interest on Form T1134 or T1135?

A nonresident LLC treated as a corporation can be a foreign affiliate; a US partnership treated as a partnership is not itself a foreign affiliate. Whether you file Form T1134 or T1135 depends on classification, ownership and the property held. Income Tax Act: foreign affiliate definition; CRA: T1135 property.

You do not report an interest in a partnership that is itself a specified Canadian entity on your T1135; if it is not, the interest may be reportable when the partnership holds specified foreign property. Recheck after ownership changes or a shift of LLC management to Canada. T1134 is generally due within 10 months after your year-end; T1135 is due by your income tax return's filing deadline, even if no return is required. CRA: T1135 partnership interests; CRA: T1134 deadline. For the full filing tests and exceptions, see Foreign property and affiliate reporting.

What changes if my Canadian corporation owns the interest?

The Canadian corporation, rather than its shareholder, is the US foreign partner. If the US partnership carries on a US trade or business, the Canadian corporation generally files Form 1120-F, claims its Form 8805 credit there and may face US branch profits tax. For a calendar-year corporation, Form 1120-F is generally due the 15th day of the fourth month after year-end if it has a US office, or the 15th day of the sixth month after year-end if it has none; a late return can lose effectively connected income deductions after the general 18 months limit. The partnership generally withholds at the corporate rate shown above. IRS: Form 1120-F instructions; IRS: Form 8805 instructions.

In Canada, the corporation files a T2 within six months after its year-end. If Canada treats the US entity as a partnership, it generally includes its allocated partnership income for the applicable fiscal period. If Canada treats the LLC as a nonresident corporation, the K-1 profit does not flow through as Canadian partnership income; review dividends, foreign affiliate income and T1134 instead. A dividend from a foreign affiliate may qualify for a section 113 deduction, including its exempt-surplus portion. A corporation with a Quebec establishment also files Revenu Québec Form CO-17. Income Tax Act: filing date; Income Tax Act: partnership income; Income Tax Act: dividends; Income Tax Act: FAPI. Corporate US tax and Canadian credits follow different rules from an individual's. Income Tax Act: section 113; Revenu Québec: Form CO-17; CRA: corporate foreign tax limits.

What if earlier K-1s or Forms 8805 were never filed?

Check each missing year separately. A K-1 does not prove that a US or Canadian filing was required, but a US partnership's trade or business can trigger Form 1040-NR even when the Form 8805 shows withholding. IRS: Form 1040-NR filing rules.

Gather the operating agreement, ownership dates, K-1s and K-3s, Forms 8805, distribution records, US tax transcripts, prior US and Canadian returns, and Canadian residency dates. Reconcile the US income and tax year by year, then check Canadian dividends, FAPI and information returns before filing or amending. A US refund claim is generally due within 3 years after filing the return or 2 years after paying tax, whichever is later; if no return was filed, the limit is 2 years after payment. A separate lookback rule can limit the refund. Check each missing year's payment date and any overdue Canadian T1134 or T1135. IRS: refund limits; 26 USC 6511. Use Cross-border tax help when the LLC classification, treaty claim or Canadian credit is uncertain.

Example

Illustrative figures only; all amounts are US dollars.

A Canadian resident owns 25% of a US LLC with US partners. The LLC earns US$400,000 of US business profit and allocates US$100,000 to the Canadian member. It pays the member US$20,000 cash. Assume the entire share is effectively connected taxable income, with no withholding reductions. The partnership also pays 37% × US$100,000 = US$37,000 of section 1446 tax for the member. Form 8805 shows US$100,000 on line 9 and US$37,000 on line 10. US law treats the tax payment as a distribution, making US$57,000 of cash and tax payments to reconcile. IRS: Form 8805; IRS: Form 8804 instructions.

The member uses the K-1 and Form 8805 to prepare Form 1040-NR. Suppose the final US federal tax on that share is US$25,000; the member can seek a US$12,000 refund by claiming the withholding. If Canada treats the LLC as a nonresident corporation, determine the Canadian treatment of both the cash and the tax paid for the member; the US$100,000 K-1 profit is not automatically Canadian income. Income Tax Act: shareholder benefits. The US$25,000 final tax therefore does not automatically become a Canadian credit. The LLC's control, income type and Canadian residency could change this result.
