CRA hints at more GST/HST reviews
If your previously filed GST/HST remittances require some adjustments, this is your chance.

In December 2016, the Canada Revenue Agency (CRA) will conduct a GST/HST compliance letter campaign pilot project. The CRA will send 250 letters in December followed by 250 in February, 2,500 in May, and 2,500 in August to GST/HST registrants. Those receiving a letter will be asked to review a previously-submitted GST/HST return with suspected errors and confirm whether the amounts they reported are correct or need to be changed.
