Bookkeeping For Landlords

Rental property owners often underestimate the complexity of real estate bookkeeping. From mortgage interest to repairs, each transaction affects your taxable income and CRA audit exposure. Mackisen CPA Auditors Montreal provides specialized bookkeeping and accounting services for landlords to ensure full CRA and Revenu Québec compliance while maximizing eligible deductions.

Legal and Regulatory Framework
Income Tax Act (Canada) Section 20(1): Defines deductible rental expenses including mortgage interest, repairs, and management fees.

Taxation Act (Quebec) Section 34: Mandates recordkeeping for property-related QST or GST filings.

Key Court Decisions
