US syndications: ask one question before you wire the funds.
Is the issuing entity an LP or an LLC? For a Canadian investor that single word decides whether you get foreign tax credits — or pay tax twice on the same return. Add 37% US withholding on your share of income, K-1s that arrive after Canadian deadlines, and a 10% withholding on early exits, and passive investing is anything but passive at tax time.

The LLC question, first and always
Most US syndications are Delaware LLCs taxed as partnerships. The US is happy; Canada is not — CRA treats an LLC as a corporation, denies the foreign tax credit for US tax paid on flow-through income, and taxes your distributions again as foreign dividends. Combined rates can exceed 70%. A true US Limited Partnership keeps flow-through treatment in both countries and preserves every credit. This is diligence question number one, before the wire — and if you're already in an LLC deal, there are mitigation options worth pricing.
What the sponsor's forms actually do
| Mechanism | What it means for you |
|---|---|
| Section 1446(a) withholding | The partnership withholds 37% (individuals) of your share of effectively connected income — whether or not cash was distributed |
| Form 8805 | Your annual statement of income and tax withheld — this is your credit voucher on the 1040-NR |
| Your 1040-NR | Files annually with ITIN; flat 37% withholding usually exceeds graduated-rate tax, so refunds are common |
| Section 1446(f) on exit | Selling your LP interest early? The buyer withholds 10% of the amount realized — including your share of the debt |
| State returns | Properties in taxing states can require nonresident state filings; Florida/Texas-only deals avoid this entirely |
The K-1 calendar problem
US partnerships routinely extend to September 15. Your K-1 and 8805 arrive months after Canada's April 30 / June 15 filing deadlines — and Canada grants no extension, for the T1 or for T1135 ($25/day penalties, tax owing or not). The working method: estimate, file on time, amend when the K-1 lands. Sponsors handle none of this — "the sponsor's CPA does the tax stuff" covers US partnership filings only, never your Canadian side.
Depreciation-heavy years cut both ways
With 100% bonus depreciation permanent again, early K-1s often show large paper losses — little or no US withholding. Those US losses have no immediate Canadian credit value, so the timing mismatch between the two countries needs managing across the life of the deal, not year by year.

Common questions.
The sponsor says foreign investors are welcome. Doesn\u2019t that mean it\u2019s fine?
It means the US side is handled. Whether Canada respects the structure — and whether you keep your foreign tax credits — is a separate question the sponsor has no reason to have answered.
I got an 8805 showing withholding. Do I need to do anything?
Yes — file a 1040-NR to claim it. The 37% flat withholding usually exceeds your actual US tax; without a return, the difference stays with the IRS.
Does my $150K LP interest go on a T1135?
If your total specified foreign property cost is over CAD $100,000, yes — an LP interest is specified foreign property. LLC interests can trigger the T1134 foreign-affiliate form instead at ≥10% ownership.
