CRA generally expects Canadian taxpayers to obtain U.S. transcripts to back up U.S. FTC claims

At the June 2016 STEP Roundtable, CRA noted that, starting in 2015, it began to no longer exempt Canadian taxpayers' claims for U.S. foreign tax credits from the approach, which it already had been applying to FTC claims for other jurisdictions, of requiring a copy of the foreign tax return as well as proof of payment of the foreign tax. In its official response published last week, CRA suggested that taxpayers get U.S. transcripts (evidencing payment) even before any CRA review and stated:

According to the IRS website “Most [transcript] requests will be processed within 10 business days”. ...

[T]he IRS has a very structured process for requesting tax account transcripts online or through the mail using Form 4506-T. … In addition, the majority of the U.S. states have an online system which allows the taxpayer to print his/her “account statement” which would confirm the taxpayer’s final tax liability.
