Mortgage broker and agent tax returns involve commission income reported through T4A slips, substantial vehicle and professional expenses, and often a mix of employed and self-employed income depending on brokerage arrangement. This checklist covers what you need to file your 2025 return accurately.
Income Documents
- All T4A slips from your brokerage (or multiple brokerages if you moved during the year)
- Commission statements or year-end summaries from your brokerage showing gross commissions, clawbacks, and referral fees paid and received
- Any referral fees received directly from clients or other brokers
- If employed at any point in 2025: T4 slip from the employer
- Interest and investment income: T5 slips
Commission clawbacks: If a client refinanced or broke their mortgage within the clawback period and you repaid commission to the lender, that repayment is a business expense. Obtain documentation of the clawback amounts from your brokerage.
Referral fees paid: Referral fees paid to other brokers, real estate agents, or others are deductible as business expenses. Keep records of each payment, the recipient, and the related transaction.
Business Expense Documents
- Brokerage fees and dues: Monthly brokerage fees, desk fees, and association membership dues (CAAMP, provincial mortgage broker associations)
- Licensing and professional development: Annual licensing fees, continuing education courses, exam fees
- Marketing and lead generation: Website costs, online advertising, business cards, printed materials, CRM subscriptions
- Technology: Mortgage software subscriptions, office productivity tools, phone
- Professional fees: Accounting and bookkeeping fees, legal fees related to business matters
- Bank charges: Business account fees and transaction costs
- Home office: Rent/mortgage interest, utilities, if you work from a dedicated home workspace (see calculation and rules)
- Vehicle expenses: Full vehicle expense details (see below)
Vehicle Expenses and Mileage Log
Vehicle expenses are significant for mortgage brokers who meet clients at properties, lenders, and lawyers’ offices.
Mileage log requirements:
- Odometer readings: January 1, 2025 and December 31, 2025
- Log of each business trip: date, destination (client name or lender), purpose, and kilometres
- Total annual km and total business km
Vehicle expense receipts:
- Fuel
- Insurance
- Maintenance and repairs
- Licence and registration
- Lease payments (if leased) or purchase details and prior-year CCA schedule (if owned)
The business-use percentage applied to total vehicle expenses must be supported by the mileage log. CRA regularly requests mileage logs for mortgage brokers claiming vehicle expenses.
Home Office Calculation
- Total home square footage
- Dedicated workspace square footage
- Annual rent (or mortgage interest, property taxes, insurance for owners)
- Annual utilities (heat, electricity, internet)
The workspace must be exclusively used for business activities.
GST/HST Documents
Mortgage brokerage commissions on residential mortgage transactions are generally exempt from GST/HST. However, some activities (such as commercial mortgage brokerage or certain finder’s fee arrangements) may be taxable. If you are registered or unsure of your registration requirement, provide:
- Total 2025 revenue broken down by type of service
- Any GST/HST collected on taxable supplies
- Input tax credit receipts for business expenses
Prior Year and Carryforward Items
- 2024 Notice of Assessment (shows RRSP room, carry-forward losses, prior-year balances)

- Charitable donations: official receipts
- Medical expenses: all receipts for the family over the 12-month period that maximizes the credit
