Putting US Income on a Canadian T1: Which Lines, Which Exchange Rate, and How the Foreign Tax Credit Is Claimed

Short version: Canadian Foreign Tax Credit Explained: Form T2209

Canada taxes residents on worldwide income, and the T1 has a place for every kind of US income — the work is finding the line, converting the currency, and claiming the credit correctly. Line by line. US employment income (a W-2): reported as foreign employment income on line 10400 (other employment income), gross of US withholding, converted to Canadian dollars; the US federal income tax withheld and paid, and the state income tax, are foreign taxes for the credit — and the Social Security and Medicare (FICA) taxes are creditable too, not as non-business income taxes (the CRA stopped treating US social security taxes that way in 2006, on the view that contributors receive specific benefits) but because the Canada-US treaty specifically obliges Canada to allow a foreign tax credit for FICA, a point worth stating because these taxes are frequently omitted. US self-employment income (a Schedule C business): reported as business income on the T2125 in Canadian dollars, with the US self-employment tax creditable as a business-income tax where the totalization agreement's coverage rules put the taxpayer in the US system, and with the treaty's business-profits article limiting US tax where no US permanent establishment exists (the kept-clients guide). US interest and dividends (a 1099-INT, 1099-DIV, or 1042-S): reported as foreign interest and dividends on line 12100 in Canadian dollars, gross of withholding, with no dividend tax credit (the Canadian dividend credit applies only to Canadian corporations' dividends — US dividends are ordinary foreign income), and the US withholding (15% under the treaty on dividends with a W-8BEN, 0% on most interest) creditable as non-business income tax. US pensions, IRAs, 401(k)s, and Social Security: US Social Security on line 11500 (other pensions) with the treaty's 15% exemption claimed as a deduction on line 25600 (so that 85% is taxed), no US tax to credit (the US doesn't tax a Canadian resident's Social Security under the treaty); IRA and 401(k) distributions on line 11500 in full, with the US withholding (15% on periodic payments with a W-8BEN, 30% on lump sums) creditable as non-business income tax — and, for taxpayers 65 and over, eligible for the pension income amount and pension splitting where the payment qualifies as periodic pension income under the Canadian definition. US rental income (a Schedule E property): reported on Form T776 in Canadian dollars — gross rent, expenses, and Canadian capital cost allowance computed under Canadian rules (the US depreciation is irrelevant to the Canadian computation; the property's Canadian cost base is its purchase price converted at the purchase date), with the US tax on the net rental income (under the net election on the 1040-NR, or the resident's 1040) creditable as non-business income tax — and with the T1135 reporting the property as specified foreign property at its cost amount. US capital gains (a 1099-B, or a property sale): reported on Schedule 3 in Canadian dollars with the gain computed from the Canadian cost base (the purchase price converted at the purchase-date rate) and the proceeds converted at the sale-date rate — so that currency movement is part of the Canadian gain even where the USD gain was zero — half included, and the US tax on the gain (for a nonresident alien, none on stock gains; FIRPTA-level tax on US real property) creditable. Currency conversion: the CRA accepts either the Bank of Canada's exchange rate on the day the income was received (the transaction-date method, precise and laborious) or the annual average rate published by the Bank of Canada (acceptable for income received throughout the year — salary, periodic pensions, dividends), used consistently; capital transactions (purchases, sales) use transaction-date rates, not annual averages; and the method chosen is documented because the credit computation uses the same conversions for the tax paid. The foreign tax credit (Form T2209 federally, the provincial form — T2036 or the province's equivalent — for the provincial portion): computed separately for non-business income tax (the credit is limited to the Canadian tax on the net foreign non-business income from that country, with any excess non-business tax generally not carried forward — it may be deductible instead under subsection 20(11) or 20(12) in some cases, a fallback for over-withheld amounts) and for business income tax (limited similarly, with a ten-year carryforward and three-year carryback for the excess); the credit is per country (the United States as one country — federal, state, and FICA taxes pooled); the provincial credit picks up the portion the federal credit couldn't absorb, computed on the provincial form; and the foreign tax must have been paid or accrued for the year and must be a genuine income tax (US state income taxes qualify; property taxes, sales taxes, and the FIRPTA or 1042-S withholding that exceeds the actual US liability do not — the withheld amount is creditable only to the extent of the final US tax, so over-withholding recovered by a US refund claim is not creditable). The reconciliation discipline: the US return's final tax (not the withholding) is the creditable amount, so the Canadian return is prepared with the US return in hand — and where the US return is filed after the Canadian deadline, the Canadian credit is claimed on the expected US tax and adjusted by T1-ADJ when the US return is finalized. The T1135 rides alongside: US accounts, US real property (non-personal-use), and US securities held with a Canadian broker are specified foreign property reported annually where the total cost exceeds C$100,000. The failure modes: omitting the FICA taxes from the credit (leaving money on the table); crediting the withholding rather than the final US tax; using annual-average rates on capital transactions; forgetting the 15% Social Security exemption; claiming the dividend tax credit on US dividends; and computing the US rental's Canadian income with US depreciation — each a T1-ADJ in a later year.

Key takeaways

• Every US dollar has a T1 line: employment (10400), business (T2125), interest and dividends (12100 — no dividend tax credit), pensions and Social Security (11500, with the 15% exemption on 25600), rental (T776 with Canadian CCA), gains (Schedule 3 from the Canadian cost base).
• Convert in Canadian dollars: transaction-date or annual-average Bank of Canada rates for periodic income (consistently); transaction-date rates for capital purchases and sales — currency movement is part of the Canadian gain.
• The credit is the final US tax, not the withholding: federal, state, and FICA taxes pooled as one country; non-business and business income taxes computed separately on T2209 with the provincial form for the overflow; over-withholding recovered by US refund is not creditable.
• Don't forget FICA: US Social Security and Medicare taxes on US employment income are creditable — the most commonly omitted item.
• Social Security's 15% exemption; IRA periodic payments' pension treatment; US rental computed under Canadian rules; US dividends as ordinary foreign income.
• The T1135 rides alongside for US accounts, non-personal-use property, and securities above C$100,000 of cost.

The US-income T1 workpaper

Per slip or source: the US form (W-2, 1099, 1042-S, Schedule E, 1099-B), the USD amount, the conversion rate and method, the CAD amount, the T1 line, the US tax paid on it (final, from the US return), and its credit category (non-business or business). Totals by category into T2209 and the provincial form; the 15% Social Security deduction on line 25600; the T1135 inventory. The workpaper is built from the US return, which is why the two returns are prepared together — and it is the document that answers the CRA's processing review of the foreign tax credit, which the review guide says arrives for this credit more than any other.

Worked example

A Toronto resident with a US employer (remote), a US brokerage account, and a Phoenix rental. W-2: US$95,000 of wages converted at the annual average rate to about C$129,000 on line 10400; US federal tax, Arizona-equivalent state tax (none — remote from Ontario; the employer withheld federal only), and FICA (about US$7,300) all pooled as creditable non-business tax. 1099-DIV and 1099-INT: US$4,200 of dividends and US$800 of interest converted to line 12100, no dividend tax credit; the 15% withheld on dividends (W-8BEN on file — though as a nonresident alien employee her wages ran through a 1040-NR, her investment withholding was at treaty rates) creditable. Phoenix rental: gross rent and expenses converted to T776, Canadian CCA computed on the property's Canadian cost base (purchase price at the purchase-date rate), net rental income taxed; the US tax on the rental's net income under her 1040-NR net election creditable. T2209: non-business income tax pooled (federal on wages and rental, FICA, dividend withholding) against the Canadian tax on the net US-source non-business income — the wages' credit fully absorbed, the rental's credit absorbed, a small excess on the dividends (where Canadian tax on ordinary foreign dividends exceeded the 15%) — no, the reverse: the 15% withholding is below the Canadian tax on the dividends, fully absorbed. Provincial form: the Ontario portion of the credit. T1135: the brokerage account and the Phoenix property (non-personal-use) above C$100,000 of cost. Her prior preparer had omitted the FICA (about C$10,000 of credit over the years, recovered by T1-ADJ for the open years) and computed the rental with US depreciation figures — two errors the workpaper structure makes impossible.

Practitioner note

US income on a Canadian return is a mapping exercise with three recurring errors — FICA left out of the credit, withholding credited instead of the final US tax, and US depreciation used on a Canadian T776 — and our US-income workpaper is built to make all three impossible: per source, the slip, the conversion, the line, and the final US tax by credit category. The workpaper is prepared from the US return, which is why we never file the Canadian return first, and it is the document the CRA's foreign-tax-credit review asks for every year.
