During construction, it’s a good idea to file
monthly so you can recover the GST you pay on building expenses as
soon as possible. When the building is complete, you may opt to
file less frequently.
You initially choose your filing period when you register for the
GST. Later, you can change your GST reporting period by submitting
a GST form 20, Election for GST Reporting Period.
The change can only take effect at the beginning of your fiscal
year. The election must be filed no later than two months after the
day it is to take effect. For example, let’s assume you
currently file annually using a calendar year, so your fiscal year
starts January 1. You are planning to start a new housing project
in April of the following year, with completion in October, and
want to file monthly during construction. You must submit the
election form by the end of February in the construction year (two
months after your fiscal year starts). To return to annual filing
the year after construction, you must submit another request by the
end of February the following year.
See page 17 in chapter one of the GST Guide for more information on
changing your GST filing frequency.
