Year-End Expense Timing: What You Can and Cannot Accelerate

You can move an expense into the fiscal year you are closing only by moving the underlying event - the goods being received, the service being performed, the obligation becoming real. You cannot move it by moving the payment. For a business reporting on the accrual basis, which covers virtually every Canadian corporation, the cheque date is close to irrelevant.

This trips up owners every year, usually in one of two directions. Some pay a pile of January invoices in late December believing they have bought a deduction; they have bought nothing except worse working capital. Others hold back December payments to conserve cash and assume they have deferred the deduction too; they have not, and their financial statements are wrong. Getting timing right is mostly about knowing which of four rules governs the item in front of you.

The 60-second version

• Accrual, not cash. Income from a business is the profit for the year [1]; an expense belongs to the year the benefit was received and the liability became certain, not the year it was paid.
• Prepaid amounts do not accelerate. Subsection 18(9) pushes prepaid services, insurance, interest and taxes into the year they actually relate to [2].
• Capital is not current. A year-end equipment purchase is added to a CCA class and deducted over years, not expensed [2][3].
• Accruing is legitimate; inventing is not. Work performed and not yet invoiced is a valid year-end accrual. Work not yet performed is not.
• Unpaid amounts to related parties come back. Section 78 adds them to income if they stay unpaid past the second following year [6].
• The line into impropriety is documentary. Change the facts before year end, never the paperwork after it.

Does the payment date decide the year an expense falls in?

No. Under the accrual method, an expense is recognized when the business becomes liable for it and the corresponding benefit is received, which normally means when goods are delivered or services are performed. The cash method - deducting when paid - is available in Canada only in limited circumstances, principally for farming and fishing businesses, and is described in guide T4002 [5]. Everyone else accrues.

Two immediate consequences for the last month of your fiscal year. First, an invoice for work done in your final month is deductible in that year even if you pay it two months later; it should be sitting in accounts payable at year end. Second, paying a supplier in advance for work scheduled for next quarter creates a prepaid asset, not a deduction. The bank balance moved; the profit did not.

This is also why the last month of the year demands a genuinely complete month-end close. The expenses most often missed at year end are the ones with no payment to trigger them: work performed in the final weeks, invoiced after the books were nominally closed, and never accrued. Those are real deductions, legitimately yours, and they vanish through sloppiness rather than any rule.

Why can I not deduct a year of software or insurance paid in December?

Because subsection 18(9) of the Income Tax Act says so [2]. It denies a current-year deduction for amounts paid for services to be rendered after the end of the year, for interest, taxes or rent relating to a period after the year, and for insurance covering a later period. The amount is deducted instead in the year to which it relates.

So a twelve-month policy or subscription paid in the final month of your fiscal year yields roughly one month of deduction this year and eleven next. The cash left in November; the deduction arrives across the following twelve months. Sometimes that is still the right decision - an annual prepayment discount can be worth more than the timing cost - but make it as a purchasing decision, not as a tax one.

The reverse is what actually creates year-end value: cost that has already been consumed but is not yet recorded. Unbilled subcontractor work, statutory amounts accrued, utilities consumed in the final period, employee expenses incurred but not yet submitted. That last category is bigger than most owners think, and it is a reporting problem rather than a tax one - see employee expense reimbursement policy for why submission deadlines belong in the policy, and expense report approval workflow for the mechanics of getting the last month in before the books close.

Is a year-end equipment purchase deductible?

Not as a current expense. Paragraph 18(1)(b) denies the deduction of a capital outlay, and paragraph 20(1)(a) then allows the cost to be recovered over time through capital cost allowance [2][3]. The practical questions at year end are which class the property falls into, what first-year rules apply, and - the one people forget - whether the property is available for use. A machine delivered on the last day of the year and still crated cannot generally be claimed as though it were in service.

The current-versus-capital distinction also governs the classic year-end repair decision. A repair that restores property to its previous condition is generally a current expense; work that materially improves the property or extends its useful life is capital [4]. Replacing broken shingles differs from replacing the roof. If you are deciding what to do before year end, that distinction changes the size of this year's deduction far more than the date on the invoice does. Our guide to CCA classes covers how each class behaves.

What can I legitimately accelerate before year end?

Plenty, as long as the underlying event actually happens inside the year:

• Do the work now. Repairs, maintenance, professional services, training, marketing production - if the service is performed before year end, it is this year's expense, whenever you pay for it.
• Take delivery now. Supplies and consumables received before year end are this year's cost. Ordered-but-not-shipped is not.
• Declare and document compensation properly. Bonuses and management fees have their own rules about when the amount must be paid before the deduction is affected; decide and document before year end rather than after.
• Write off what is genuinely gone. Bad debts and obsolete inventory belong in the year the determination is made, not the year you get around to it.
• Capture the receipts you already have. Personal cards used for business purchases in the final weeks are among the most commonly missed expenses of the year; see shareholder loan account and personal credit card purchases.

MapleExpense helps with the last of these: receipts forwarded or photographed as they occur are extracted and categorized when they happen, so the final-month expenses are already in the ledger at year end instead of surfacing in February when someone cleans out a wallet. It does not decide the accrual for you, but it removes the most common reason a legitimate deduction is lost - the receipt that never made it into the system at all.

Where exactly is the line into impropriety?

The line is the difference between arranging your affairs before the year closes and rewriting what happened after it closed.

On the legitimate side: deciding in November to do the repair in December; ordering supplies early enough that they arrive before year end; accruing an invoice for work genuinely performed in the final week; electing an available method and applying it consistently.

On the other side: asking a supplier to date an invoice to a period in which nothing was supplied; dating a cheque into a closed year; recording an accrual for a service that will not be performed until spring; or splitting a capital purchase into small invoices so it looks like current expense. These are not aggressive positions. They are false statements in a return, and subsection 163(2) provides for a penalty where a false statement is made knowingly or in circumstances amounting to gross negligence [7], with section 239 reserving prosecution for the serious end.

The defence against the accusation, in either direction, is the same thing: contemporaneous records showing when the work was done, what was received, and when the obligation arose. That is exactly what section 230 requires you to keep anyway [8], and the retention rules are covered in books and records retention.

One more trap: amounts owed to yourself

Small corporations frequently accrue management fees, interest, or rent payable to the owner at year end, deduct them, and then never actually pay. Section 78 addresses this: where a deducted amount payable to a non-arm's-length person remains unpaid at the end of the second taxation year following the year of deduction, it is generally brought back into income unless a joint election is filed [6]. The deduction was real. It was also temporary, and the clock started the day it was claimed.

Is accelerating expenses even worth the cash?

Often, no. A deduction saves tax at your corporate rate; paying early costs you the full amount now. For a corporation paying tax at small-business rates, prepaying a dollar to save a fraction of a dollar, months early, is a working-capital decision disguised as a tax decision - and it is a bad one in any year when cash is tight or an instalment stream is starting. Before accelerating anything, check it against your instalment obligations: the business that spends December buying deductions and January missing an instalment has converted a small tax saving into non-deductible interest.

Frequently asked questions

Can you deduct an expense in the year you paid it?

Not necessarily. A business computing income on the accrual basis - which corporations and most unincorporated businesses in Canada must do - deducts an expense in the year the goods or services are received and the liability becomes certain, regardless of when the invoice is paid. Paying a January invoice in December does not move the deduction into December, and leaving a December invoice unpaid at year end does not push it into January. The cash-basis exception is narrow and applies mainly to farming and fishing businesses.

What is the rule for prepaid expenses in Canada?

Subsection 18(9) of the Income Tax Act prevents a business from deducting, in the current year, an amount paid for services to be rendered after the end of that year, for interest or taxes relating to a later period, or for insurance covering a later period. The amount is instead deducted in the year to which it relates. In practice, a twelve-month subscription or insurance policy paid in the last month of your fiscal year is deductible roughly one twelfth this year and eleven twelfths next year, not in full when paid.

Can I buy equipment before year end to reduce this year's tax?

Buying equipment before year end does not create a full deduction, because a capital outlay is not deductible as a current expense under paragraph 18(1)(b) of the Income Tax Act. Instead it is added to a capital cost allowance class and deducted over several years under paragraph 20(1)(a). Two conditions matter more than the purchase date: the property must be acquired and available for use, and the applicable CCA class and rate determine how much of the cost is claimable in the first year. Equipment bought in the last week of the year uses a full year of cash for a fraction of a deduction.

What is the difference between year-end tax planning and backdating?

Planning changes the facts before the year ends: you actually order the supplies in December, the contractor actually performs the work in December, the repair actually happens in December. Backdating changes the record after the fact to claim an expense the business did not incur in that period - altering an invoice date, dating a cheque to a period that has closed, or booking an accrual for work nobody performed. The first is legitimate and routine. The second is a false statement in a return, exposing the taxpayer to gross negligence penalties under subsection 163(2) and, in serious cases, prosecution under section 239 of the Income Tax Act.

Can you accrue an expense at year end without an invoice?

Yes, if the liability genuinely exists at year end and can be measured with reasonable accuracy. Work performed in December and invoiced in January is a December expense and should be accrued, supported by evidence such as a contract, a purchase order, a timesheet, or the invoice itself once it arrives. What is not permitted is accruing for something that was merely anticipated - a service not yet performed, a discretionary bonus not yet declared, or a cost booked to a period simply because that is where the deduction would be more valuable.

What happens to an expense owed to a related party that stays unpaid?

Section 78 of the Income Tax Act addresses unpaid amounts owing to a person with whom the taxpayer does not deal at arm's length. If a deducted expense payable to a non-arm's-length person remains unpaid by the end of the second taxation year after the year of deduction, the amount is generally added back to the debtor's income for that later year unless a joint election is filed. This directly affects small corporations that accrue management fees or interest to an owner and then never actually pay them.

Does a deposit paid before year end count as an expense?

Usually not. A deposit or advance is a prepayment for goods or services not yet received, so it sits on the balance sheet as an asset until the supplier delivers. It becomes an expense when the goods are received or the services are performed. The same logic applies to retainers: paying a lawyer or accountant a retainer in the final week of the fiscal year creates a prepaid asset, not a deduction, unless the work has already been done by year end.
