Important Changes To US Tax Filing Deadlines For Canadians

On July 31, 2015, President Obama signed into law the "Surface Transportation and Veterans Health Care Choice Improvement Act of 2015" (the Act). Although the Act was not primarily tax focused, it nevertheless contained several important changes to US tax filing deadlines, which may catch Canadians who have US tax and filing obligations off-guard.

New extended filing deadline for some (but not all) US corporate returns

Under prior law, the filing deadline for US corporations (that is, corporations subject to the US corporate income tax), was the fifteenth day of the third month following the end of the taxable year. Under the new rules, which generally apply to taxable years beginning after December 31, 2015, the filing deadline has been extended to the fifteenth day of the fourth month following the end of the taxable year.
