For the savvy entrepreneur, understanding the concepts of ITCs and ITRs is essential.

A ITC is essentially a credit that businesses can claim to recover the GST they paid when purchasing inputs, that is, goods or services necessary for the operation of their business. For its part, the ITR is the equivalent of the ITC but for the QST.
