Capital Cost Allowance on the T2125: How CCA Works for Canadian Sole Proprietors

Capital Cost Allowance Confuses Most Sole Proprietors

When you buy a $2,500 laptop or a $40,000 vehicle for your Canadian sole proprietorship, you cannot just deduct the full amount on your T2125 the year you buy it. That is what trips up most freelancers. Big-ticket purchases are capital property, and the CRA makes you deduct them over several years using a system called Capital Cost Allowance (CCA).

CCA is the CRA's version of depreciation. Instead of expensing the asset at once, you write off a percentage of its remaining value each year on a separate part of the T2125.

Current Expense vs. Capital Expense: The Key Test

The first decision is whether a purchase is a current expense (deduct in full this year) or a capital expense (claim CCA over time). The CRA generally asks:

Small tools or supplies under a few hundred dollars are usually fine as current expenses. Once you are spending into the thousands on equipment, expect to use CCA.

How CCA Works on the T2125

Every depreciable asset gets sorted into a CCA class with its own rate. You enter your year-end CCA claim on Line 9936 in Part 4 of the T2125. The calculation lives in Area A of the form, where you list:

The CCA percentage is applied to the UCC, not the original cost, so each year the deductible amount gets smaller as the pool depreciates.

Common CCA Classes for Freelancers

Most sole proprietors only deal with a handful of classes:

When in doubt, check the CRA's published class list before filing.

The Half-Year Rule

In the year you buy an asset, you can usually only claim CCA on half the addition. This is the half-year rule, and it prevents you from buying a $5,000 laptop in December and claiming a full year of depreciation on it.

There are exceptions — notably the Accelerated Investment Incentive for eligible property, which lets you claim a higher amount in the first year. The exact treatment depends on the asset class and when it was put into use, so check the rules for your specific purchase.

Selling a Capital Asset: Watch for Recapture

If you sell a business asset for more than its remaining UCC, the CRA can claw back prior CCA as recapture and include it in income. If you sell for less than UCC, you may have a terminal loss to deduct. Either way, dispositions need to be recorded in Area A of the T2125, not buried in your bank statements.

You Cannot Claim Mileage and CCA Together

For vehicles, freelancers often ask if they can claim a per-kilometre rate and CCA. You cannot. Sole proprietors generally claim actual vehicle expenses (including CCA) multiplied by business-use percentage. The per-kilometre rate is mainly for tax-free employee reimbursements, not self-employed claims.

A Quick Worked Example

Say you buy a $3,000 laptop in March for 100% business use. It is Class 50 (55%).

You keep claiming a shrinking amount each year until the pool is fully depreciated or you sell the asset.

Track Capital Purchases Separately All Year

The cleanest way to survive CCA at tax time is to log capital purchases as you go, separated from current expenses. ClaimHero lets Canadian sole proprietors categorize expenses by T2125 line throughout the year — including notes on equipment and vehicle purchases — so your accountant has everything they need to calculate CCA.
