If you are a senior with a lower income, you might be entitled to receive the GST/HST credit. It is important to note that to be eligible for this credit, you must file your income tax returns, even if there was no income. The credit is restricted to one spouse or common-law partner, which means that both cannot claim it. The credit will be granted to the individual who first made the request for it, notwithstanding the person who eventually receives the payment, which is generally the same amount.
