Partnerships file partnership and look-through company income tax returns each year. These returns show how much profit or loss was shared between each partner.
Partnerships do not pay income tax on their profits. Instead, the profit or loss is shared between the partners. The partners separately pay income tax on any profit, and they can also claim any partnership losses against their own personal income.
Each partner also needs to file their own Individual income tax return showing their partnership income or losses.
