For a t3 the box 34 foreign non business income tax paid is 84.54 and shows that on FTC. Carry fwd to T2209 is 67.08 cannot override. There is no calculation showing why

Have you been able to resolve this issue?  I am having the same problem.  Thanks

Review the federal schedule 1 and the provincial schedule ??428 for split FTC. The remainder may also transfer to Line 232 on the T1 General.

I'm sorry but this doesn't answer the above question.  I am having the same problem.  Why is the amount of foreign tax paid(Box 34 of my T3) not the same as the amount populated on Line 431 of T2209S?  Thanks

What is the source of your foreign income in 2017 and how much are you reporting for tax purposes.

The source is US however it is being reported on the T3 in Cdn $.The income shows up alright as canadian with no exchange rate conversion. I don't think there was an option on turbo tax to say what the source was it automatically defaulted to US. The foreign non business income was 447.23 which is in cdn $ as is the foreign income tax paid of 85.54 all from the T3. Also as a note the T3 form says box 34 - Foreign non business income tax paid - Include this amount on line 1 of Form T2209. It does not say to adjust it.

US Index fund, from T3 Box 25 is $3662.89 and Box 34 foreign tax paid is $638.63. The amount populated on T2209S Line 431 is $549.43
