I am in Canada and I have some rental properties. I want to ask if principal in mortgage payment should be counted as net-income or taxable income? I always think the principal part of mortgage payment is tax free income. I should only pay tax if I have positive cash flow. But my accountant told me that even my property break even with 0 cash-flow after mortgage payment. I still have principal as income, because only Interest is expense. So my principal become net-income and it is taxable. I can only claim depreciation to defer the tax. Is it true? It is against my knowledge that equity & principal is tax free income. Please clarify.
