Realtor Home Office Deduction Canada 2025 — T2125 Workspace Claim Guide

Updated March 2026 · Realtor home office deduction Canada · 7-minute read

Most Canadian realtors work primarily from home — making calls, writing offers, doing market research, and managing client relationships. The workspace-in-home deduction allows self-employed realtors to deduct a portion of their home expenses as a business cost. This deduction can reduce taxable income by $3,000–$100+ per year depending on your home costs and office size.

CRA Requirements for the Workspace-in-Home Deduction

To claim a workspace-in-home deduction on T2125 (Part 7), your home workspace must meet one of two conditions:

The workspace is your principal place of business — meaning it is where you primarily conduct your business, OR
The workspace is used exclusively and on a regular and continuous basis for meeting clients, customers, or patients in your business.

Most realtors satisfy condition 1 easily — their home office is where they do the majority of their paperwork, client communication, and administrative work. The key word is "exclusively" — a dedicated room used as a home office qualifies; a kitchen table used sometimes for work does not.

The "Exclusively Used" Requirement

The CRA requires the workspace to be used exclusively (or almost exclusively) for business purposes. A dedicated spare bedroom converted to an office works. A corner of your living room where you also watch TV does not. Invest in a door. Document the space with photos. Do not have a guest bed in your "office."

How to Calculate the Deduction

The deduction is calculated using the square footage method:

Business-use % = Office sq ft ÷ Total home sq ft

Apply this percentage to eligible home expenses to get your deductible amount.

Eligible Expenses by Situation

Expense	Renters	Homeowners
Rent	Yes — business % of annual rent	N/A
Mortgage Interest	N/A	Yes — business % of annual interest
Property Tax	N/A	Yes — business %
Home Insurance	Yes — business %	Yes — business %
Utilities (heat, hydro, water)	Yes — business %	Yes — business %
Internet (home portion)	Yes — business %	Yes — business %
Maintenance & Repairs	Business % of general repairs	Business % of general repairs
Capital improvements	No	No (CCA may apply separately)
Mortgage principal	N/A	No

Important: The No-Loss Rule

Your workspace-in-home deduction cannot create or increase a business loss. If your net business income (before the home office deduction) is $15,000 and your calculated home office deduction is $20,000, you can only deduct $15,000 this year. The remaining $5,000 carries forward to the next tax year indefinitely. Track your carry-forward amounts carefully — they can accumulate and be used in high-income years.

Documenting Your Home Office

Take dated photos of the workspace showing it is a dedicated business area
Measure square footage of the office and the total home — keep a note of these figures
Keep copies of all utility bills, mortgage statements, property tax bills, and insurance documents
If you renovate the office space, keep all receipts — some renovation costs may be claimable
Note on your T2125: the CRA has an optional home office expense worksheet that is useful to prepare even if not required

FAQs

Can I claim home office expenses if I also have a brokerage office?

Yes, as long as your home is your principal place of business. Many realtors use the brokerage office only occasionally and do most of their work from home. The key is that the home office is where you primarily conduct your business activities.

Does a home office deduction affect my capital gains when I sell my home?

Potentially. If you claim CCA on the home office portion (which most self-employed people choose NOT to do), it can affect your principal residence exemption. Most realtors wisely avoid claiming CCA on their home to preserve the full principal residence exemption.

Can I deduct the cost of furniture in my home office?

Yes — office furniture (desk, chair, filing cabinet) used exclusively for business is deductible, either as a current expense (if under $500) or via CCA as a Class 8 asset (20% declining balance). Keep receipts and note the business purpose.
