Tax Already Paid in China: Can You Claim It in Canada?

How to use the foreign tax credit, which records to keep, what happens when the credit can't all be used

Scott Tang, CPAUpdated 2026-11-052026 rules4 min read

You have already paid individual income tax in China on your wages or rent there, and Canada also wants you to report your worldwide income — but in general you won't pay the full tax twice. Canada has a foreign tax credit: income tax you paid abroad on a piece of foreign income can be credited against the Canadian tax on that same income. But the credit has a limit: at most, it covers "the tax Canada would have charged on that income".

T2209

The form for calculating the federal foreign tax credit; the provincial part is calculated separately

Country by country

China, Hong Kong and the US each have their own limit

15%

For individuals, foreign tax on property income other than real estate (such as dividends and interest) is credited at no more than 15% (also subject to the Canadian tax limit); the excess can be deducted

Same exchange rate

Convert the income and the foreign tax to Canadian dollars at the same rate

How much you can claim: the lower of two amounts

Item	Income tax actually paid in China	Canadian tax on this income from China
What it is	Income tax payable under the treaty and actually paid	The Canadian tax on this net income (calculated proportionally)
Credit	The lower of the two	The lower of the two

A simplified example: net rental income from China equal to C$20,000.

China's tax is lower

Paid in China 2,000

Canada would charge 4,000

Credit 2,000

Canada collects another 2,000

4,000 in total, the same as paying tax only in Canada

China's tax is higher

Paid in China 5,000

Canada would charge 4,000

Credit limited to 4,000

Canadian tax: 0

The extra 1,000 can't be refunded or carried forward to later years; if you have other non-business income from China in the same year, it is combined when working out the credit limit

So overall, you roughly pay tax at whichever of the two rates is higher.

The rules differ by type of income

Points to watch

Only "income tax" can be credited
Individual income tax can be credited; building management fees and agent fees are not taxes. In the consolidated collection (综合征收) common for rented homes in China, only the individual income tax portion counts as income tax; property tax, value-added tax and similar taxes can't be claimed as a foreign tax credit, and whether they can be treated as an expense, added to the cost or counted as a selling expense depends on the nature of the payment.
Only for the period you were resident
Foreign tax can be credited only on income earned while you were a Canadian resident.
Reclaim over-withheld tax at source
Tax withheld above the treaty limit generally can't be credited; you need to apply for a refund from the source country.
Adjust if China changes your tax
If you later get a tax refund in China, or pay additional tax there, the credit in Canada must be adjusted too.
Keep your records
Tax payment certificates, withholding certificates and bank statements — these are what the CRA most often asks for when it reviews a return, and if you can't produce them, the credit may be denied.

We calculate the T2209 and the provincial credit separately for income from China, Hong Kong and the US, and handle the 15% limit and the deduction together.
