If your foreign tax credit is showing as $0, there are three possible reasons:

1. Missing foreign tax information
   • Check if you've entered the amount of foreign tax paid in your profile
   • Navigate to the relevant income section (e.g., Employment Income, Investment Income, Rental Income) and ensure you've entered the foreign tax amount
2. No federal tax payable
   • Your foreign tax credit is limited by the amount on line 42900 of your Schedule 1
   • If you don't owe any federal tax, there's no amount to be credited
3. Low foreign income or tax amounts
   • The foreign income or tax paid might be too low to result in a credit
   • Review your entries to ensure they're accurate and complete

To resolve this issue:

1. Double-check your foreign income entries
   • Go to the relevant income sections in your profile (e.g., Employment Income, Investment Income)
   • Verify that you've reported all foreign income correctly
2. Review your foreign tax paid entries
   • Ensure you've entered all foreign taxes paid in the appropriate sections
3. Check your T1 and Schedule 1
   • Locate your T1 and Schedule 1 in the Documents section of your profile
   • Verify the amount on line 42900

If you've confirmed all information is correct and still have questions, consider consulting a tax expert or a tax professional familiar with international tax situations.
