Should I Claim CCA? When to Skip a Year

You bought a computer, a vehicle or some tools for your business. Your accounting software works out the year's capital cost allowance (CCA) and enters it automatically. Many self-employed people do not realise they are allowed to turn that amount down, in full or in part — and that in some years, turning it down pays better than deducting it.

“Optional” means anything from zero to the maximum

A durable asset is not deducted all at once. Its cost is spread over several years, through the capital cost allowance, or CCA. If the mechanism is new to you, start with our introduction to CCA; the rest of this article assumes it is understood.

What many people miss is that the year's amount is in no way compulsory. The CRA's T4002 guide puts it in one sentence: you do not have to claim the maximum amount of CCA in any given year, and you can claim any amount you like, from zero to the maximum allowed for the year.

Each year, for each class of property, you therefore have three choices:

• claim the maximum allowed;
• claim only part of it;
• claim nothing at all.

One obligation remains. Even if you claim zero, the CRA asks you to fill in the appropriate areas of the form anyway, to show the additions and dispositions of the year. You report the asset; you simply choose not to depreciate it this time.

What you do not claim is not lost

This is the point that unlocks everything else. CCA you do not claim does not vanish: it stays in the balance of its class.

Each class of property carries a balance — what is left to depreciate. CCA is worked out on a declining balance basis: the class rate applies to the balance that remains, not to the original purchase price. Every deduction cuts that balance by the same amount, and therefore cuts the CCA available in later years.

The reverse is just as true, and that is where your room to manoeuvre lies. A year without CCA leaves the balance untouched. The following year, the same rate applies to a bigger balance, so the deduction is bigger. Nothing is lost; everything is shifted.

Why the same deduction is not worth the same every year

A deduction does not hand you back its own amount. It takes that amount off your taxable income, and what you save depends on the tax rate that applied to that slice of income.

That rate has a name: your marginal rate. It is the percentage of tax that applies to your last dollar earned — not to your whole income, only to the top slice. And it climbs in steps. Here are the federal brackets for 2026:

Read the table like this: a self-employed person whose taxable income sits around $40,000 has their last dollar taxed at 14% federally; someone reporting $125,000 has it taxed at 26%. Same deduction, close to twice the saving for the second.

In Quebec, two taxes stack

In Quebec, the federal rate is only half the story: a Quebec tax applies on top, with steps of its own. What matters to you is therefore the combined marginal rate, both taxes together.

Our Quebec calculator shows it from your income. Two reference points, for 2026:

• around $40,000 of income, the combined marginal rate sits near 25.7%;
• around $125,000, it sits near 45.7%.

Take a CCA claim of $5,000. Claimed in the $40,000 year, it saves you about $1,285 in tax. Deferred to the $125,000 year, the same deduction is worth about $2,285. That is $1,000 of difference, for exactly the same purchase and exactly the same spending.

Four situations where waiting is the better call

1. The year is thin. Income down, a contract lost, a long leave. Your marginal rate is at its floor, so the deduction is worth the least it can be worth.

2. You already owe no tax. If your income is low enough that your tax bill is already nil, one more deduction brings you nothing. It would simply be wasted.

3. It is your first year in business. A business starting up rarely earns its full income in the first months, yet that is precisely the year it buys the most equipment. Depreciating straight away means spending the deduction at the worst moment.

4. You know a big year is coming. A contract signed for next year, the end of a parental leave, a rate revised upwards: if your income is about to cross a step, the deduction will be worth more on the other side.

What deferring also costs you

Deferring is not free. Three trade-offs deserve weighing before you give up a deduction.

The money comes later. A tax saving collected twelve months from now is not worth the same sum today, especially for a business that has to fund its working capital.

A declining balance is in no hurry. Because the rate applies each year to the balance that remains, the deduction comes back in smaller and smaller slices. It never disappears, but it can take a long time to come out.

Next year is not guaranteed. The big contract can fall through. Deferring a deduction means betting on future income, and that bet is sometimes lost.

One last point of timing: in the year of the purchase, CCA is generally worked out on half of the additions only — the half-year rule, covered in our article on when to buy an asset. CCA is also based on your fiscal period, not on the calendar year.

How to decide, in practice

The decision comes down to four moves, to be repeated every year.

1. Estimate this year's taxable income, once all your other business expenses are deducted.
2. Estimate next year's, even roughly.
3. Compare the two marginal rates. If the gap is only a few points, take the deduction now: money today beats a small gain later. If the gap runs to ten points or more, deferring is worth serious thought.
4. Fill in the form either way, even for a CCA of zero, showing the year's purchases and sales.

And remember that the choice is not all-or-nothing: you can claim part of the maximum — just enough to bring your income down to the bottom of a step — and keep the rest for later. That is often the smartest answer.
