Credit of 1% on the first $30,000 of
eligible supplies
In calculating your net tax using the quick method, you are
entitled to a 1% credit on the first $30,000 of your eligible
supplies (including the GST/HST) on which you must
collect the GST at 5% or the HST at the applicable rate (see
the chart on page in each fiscal year.
To qualify for the 1% credit, your quick method election
must be in effect at the beginning of a fiscal year or, if you
are a new registrant, on the day you became a registrant.
If you file monthly or quarterly GST/HST returns, the 1%
credit applies to the first and the following reporting
periods of a fiscal year until you reach the $30,000
threshold, or the fiscal year ends. If you file annual
GST/HST returns, use the 1% credit on your first $30,000
of eligible supplies in that fiscal year.
If the 0% remittance rate applies to your eligible sales, you
are entitled to the 1% credit in addition to the credit given
to businesses that purchase goods for resale (for more
information, see the remittance rates chart on page 9).
Note
If you do not make $30,000 in eligible supplies in a fiscal
year, you cannot carry forward any unused portion of
the credit to a later fiscal year.
