Personal vs Business Use of Assets: What Canadian Business Owners Need to Know

Many small business owners in Canada use the same assets — vehicles, equipment, tools, even their home — for both personal and business purposes. While this is common, it comes with important tax implications that can impact your deductions, GST/HST claims, and corporate tax filings.

Understanding how to properly separate personal and business use is essential for accurate bookkeeping, maximising deductions, and staying compliant with CRA requirements.

This guide breaks down everything you need to know.

1. What Does “Personal vs Business Use” Actually Mean?

A business-use asset is something used to earn income. A personal-use asset is something used for everyday life.

Many assets fall into both categories:

  • Vehicles used for deliveries and school runs
  • Home office spaces used for work and family
  • Equipment used for side jobs and personal projects
  • Farm tools used for both commercial and private land

When an asset is mixed-use, CRA requires you to calculate and claim only the business-use percentage.


2. Why This Matters for Tax Filing

Misreporting business vs personal use affects:

  • Income tax deductions
  • GST/HST input tax credits (ITCs)
  • Capital Cost Allowance (CCA)
  • Corporate tax filing (T2)
  • CRA audit outcomes

If CRA reviews your return, they will ask how much of the asset is actually used for business — and you must be able to prove it.


3. The Most Common Mixed-Use Assets

1. Vehicles

This is the #1 area CRA consider during audits/reviews.

You must track:

  • Business kilometres
  • Personal kilometres
  • Total annual kilometres

Only the business percentage of fuel, repairs, insurance, leasing, and depreciation can be claimed.

2. Home Office

To claim home-office expenses, the space must be:

  • Your principal place of business or
  • Used regularly & exclusively to earn income

You can deduct a percentage of:

  • Utilities
  • Rent
  • Internet
  • Mortgage interest (limited)
  • Property taxes
  • Maintenance

3. Equipment & Tools

If tools or equipment (e.g., cameras, machinery, laptops, tractors) are shared, you must prorate the use.

4. Phones & Internet

You can only deduct the portion related to business calls, data, and usage.


4. How CRA Expects You to Separate Use

CRA requires reasonable, supportable records, such as:

  • Mileage logbooks
  • Receipts
  • Digital usage reports
  • Calendar or appointment logs
  • Work vs personal hour breakdowns

If you can’t show your business-use percentage, CRA may deny the deduction entirely.


5. Asset Depreciation (CCA) Rules for Mixed-Use Assets

Capital assets such as:

  • Vehicles
  • Farm machinery
  • Office furniture
  • Computers
  • Equipment

are depreciated using Capital Cost Allowance (CCA).

For mixed-use assets, you can only claim the business-use portion.

Example:

A $30,000 vehicle used 60% for business → CCA can only be claimed on $18,000.


6. GST/HST Input Tax Credits (ITCs)

You can only claim ITCs on the business-use portion of:

  • Purchases
  • Expenses
  • Leases
  • Repairs
  • Equipment

Claiming 100% ITCs for a mixed-use asset is a common CRA audit red flag.


7. What Happens If You Misreport?

CRA may reassess your:

  • T1 personal tax return
  • T2 corporate return
  • GST/HST filings

This can result in:

Denied deductions

GST/HST ITC clawbacks

  • Interest charges
  • Penalties
  • Multi-year audits

Accurate reporting protects your business.
