Married couples, common-law couples and same-sex couples are treated the same for tax purposes. A same-sex partner is considered a common-law partner. A common-law partner is defined as someone who has cohabited in a conjugal relationship with another individual for at least one year or is the parent of a child of the other taxpayer.
