Small Business Loans in Canada and Their Tax Impact

A small business loan is not taxable income, and repaying the principal is not a deduction. Only the interest is deductible, and only where the borrowed money was used to earn business income. Financing fees spread over five years, and a forgivable portion of a government loan is usually income in the year it arrives.

That is the whole answer in four sentences, and almost every mistake owners make with business debt is a variation on one of them. The money lands in the account, the payments start, and a set of tax consequences begins that most owners never see until the corporate return is being prepared. This guide works through the tax impact of small business loans in Canada in the order the questions actually come up, for owner-managed corporations and sole proprietors alike, the way a professional tax accountant handling bank financing support would work through it with you before the loan is signed rather than after the assessment arrives.

01

Principal is not income, and repaying it is not a deduction

Start with the part that trips up more owner-managed businesses than any other single item. When a bank advances $150,000 to your corporation, that $150,000 is not revenue. It does not go on the income statement, it does not increase taxable income, and it is not reported on the T2 as income of any kind. It is a liability: the business now owes money, and the balance sheet records that. Nothing taxable has happened.

The mirror image is where the tax cost hides. Because the advance was not income, the repayment of that same principal is not an expense. Every dollar of principal you pay back is simply the liability shrinking. It never touches the profit-and-loss statement and it never reduces taxable income. Only the interest portion of each payment is a deduction, and only if it meets the conditions in the next section.

This matters because of how loan payments feel. A business paying $2,850 a month on a term loan experiences $2,850 a month leaving the bank account. If the books treat the whole payment as an expense, the year-end statements understate profit — sometimes badly — and the corporate return that follows understates tax. That gets corrected at some point, and the correction is never welcome: the tax was always owed, and arrears interest has been running on it in the meantime. Splitting each payment properly is the single most valuable bookkeeping habit around debt, and it is covered in section twelve.

Common mistake

Coding the full loan payment to an expense account called "loan repayment" or "bank charges". The principal portion is not deductible, so the statements show less profit than the business made and the tax return is wrong from the first entry. A lender reading those same statements also sees a business that looks weaker than it is.

02

When loan interest is deductible: the four conditions

Interest is not automatically deductible in Canada. Paragraph 20(1)(c) of the Income Tax Act allows a deduction for interest only where four things are true at once, and the fourth is the one that decides most disputes.

First, there must be a legal obligation to pay the interest. An informal family arrangement with no written terms and no enforceable obligation does not create a deduction, however real the payments are. Second, the amount must be interest on borrowed money — a fee that is genuinely something else does not become interest because the loan agreement uses the word. Third, the rate must be reasonable in the circumstances. Fourth, and decisively, the borrowed money must have been used for the purpose of earning income from a business or property.

That fourth condition is about use, not about the security given. A loan secured against the owner's home, used entirely to buy inventory for the corporation, produces deductible interest because the money went into an income-earning use. A loan secured against a commercial building, used to buy a family car, does not. The CRA looks at where the money actually went, and the tracing is your job to evidence — which means the loan proceeds should land in the business account and be spent from there, not routed through a personal account on the way.

Mixed use is where owners lose deductions they were entitled to. If $100,000 is borrowed and $70,000 goes into the business while $30,000 pays down a personal credit card, only 70 per cent of the interest is deductible, and only if you can show the split. Where the tracing has been lost, the CRA is not obliged to accept a favourable estimate. A short conversation about structure before the money moves is worth more than any amount of reconstruction afterwards; that is ordinary work for a firm doing cash flow forecasting alongside the financing.

How it works

Deductibility follows the use of the borrowed money, not the asset pledged as security. Two businesses can pledge identical collateral and get opposite answers, because one spent the proceeds on income-earning activity and the other spent them on something personal.

03

Financing fees and the five-year rule

Loans arrive with costs that are not interest: arrangement and commitment fees, the lender's legal costs charged to you, appraisal and registration costs, guarantee fees, and the accounting fees for preparing the statements the lender demanded. These are real cash costs of borrowing, and most owners expense them in the year they are paid. That is usually wrong.

Paragraph 20(1)(e) treats most costs incurred in the course of borrowing money as deductible over five years — twenty per cent a year, prorated in a short taxation year — rather than immediately. The logic is that the cost was incurred to obtain financing that benefits several years, so the deduction is spread across them. Standby charges and guarantee fees can fall under a related provision and be deductible annually instead, and where a loan is repaid early the unamortised balance can generally be claimed in the year the obligation ends.

Two practical consequences follow. The first is a timing difference the year-end statements need to show correctly, which means the fee sits on the balance sheet and releases into expense over the five years rather than disappearing into a single year's professional fees. The second is that the deduction survives: it is not lost, only deferred, and a business that expensed the whole amount in year one has claimed too much now and will claim nothing later.

Borrowing to buy equipment: two claims, not one

When a loan funds a piece of equipment, there are two separate deductions running in parallel and they are easy to confuse. The equipment itself is a capital asset: it goes on the balance sheet and is written off over time through capital cost allowance, at the rate for its class. The loan is a separate arrangement: its interest is deductible under the rules above. The purchase price of the equipment is never an outright expense simply because it was financed, and the loan principal is never depreciated.

Getting this wrong in either direction is expensive. Expensing a financed asset in full overstates the deduction and invites reassessment. Treating the loan payments as the only cost of the asset — and never setting up the asset or claiming CCA — leaves a real deduction unclaimed year after year. If you want to see how the write-off actually profiles over the life of an asset, our capital cost allowance calculator works through a class and a cost without any guesswork,.

There is a related trap with leases. A capital lease and an equipment loan can produce almost identical monthly cash flow while being treated very differently for tax, because a true lease payment is generally deductible in full while a purchase financed by a loan produces CCA plus interest. Which one you have is a question about the substance of the agreement, not the word printed at the top of it, and it is worth resolving before the first payment rather than at year-end.

05

Government-backed lending and the registration fee

Many small business loans in Canada are made under the Canada Small Business Financing Program. The structure matters for tax because of what the programme is: the loan still comes from a bank or credit union on commercial terms, and the government's role is to share the lender's loss if the loan defaults. It is not a grant, it is not forgivable, and nothing about it changes the basic treatment. Interest is deductible on the ordinary conditions; principal is not.

The programme charges a registration fee of two per cent of the amount loaned, payable to the government by the lender and normally passed on to the borrower and financed into the loan. Because the fee is a cost incurred in the course of borrowing money, it generally falls under the five-year rule rather than being expensed on day one. There is also an annual administration charge built into the interest rate the lender charges you, which simply forms part of the interest.

The practical value of the programme to a small business is access rather than tax: it exists so that a lender will advance funds against equipment and leasehold improvements where the security alone would not support the loan. That is why the paperwork is heavier and why lenders ask for statements prepared to a recognisable standard, which is the subject of the last section.

06

Forgivable loans: why free money shows up as income

Government support for small business is often delivered as a loan with a forgivable portion — repay a defined amount by a deadline and the rest is written off. The cash feels like a loan. Part of it is treated for tax like a subsidy, and that surprises people every time.

Where an amount is received as government assistance in respect of the cost of property or an outlay or expense, paragraph 12(1)(x) generally includes it in income in the year it is received. For a forgivable loan, that reaches the forgivable portion, and the timing is what stings: the income inclusion can land in the year the money arrives, well before the year the forgiveness is confirmed. A business that received support in one year and quietly carried the whole amount as a liability has an unreported income inclusion sitting on its balance sheet.

There is an alternative. Subsection 12(2.2) permits an election to reduce the cost of the related property or the amount of the related expense instead of taking the assistance into income. That can be the better answer, particularly where the assistance funded a depreciable asset, because it lowers the base on which CCA is claimed rather than creating an immediate inclusion. It is an election, with its own requirements, so it has to be made deliberately on a filed return and not assumed.

Watch the year

If the business ever received a loan with a forgivable component, check which taxation year the forgivable portion was brought into income, and whether an election was filed to reduce a cost instead. Finding an unreported inclusion yourself is a very different conversation with the CRA than having it found for you.

07

Settling a loan for less than you owe

Sometimes a commercial loan is settled for less than the principal outstanding: a negotiated write-down, a compromise with a lender, a formal proposal. The relief is real, and so is the tax machinery that follows it. Section 80 of the Act deals with the settlement of commercial debt, and its effect is to make the forgiven amount work through a defined sequence rather than simply vanish.

Broadly, the forgiven amount is applied to reduce the debtor's loss balances in a prescribed order — non-capital losses first, then other balances — and where balances run out, part of the remaining amount can be included in income, with relief available in some circumstances through a reserve or an election to apply the amount against the cost of certain property. The design is deliberate: the business got the benefit of a deduction when the expense was incurred, so relief from paying the debt cannot also be tax-free.

Two points follow for an owner facing a workout. The first is that the tax outcome depends on balances the corporation already has, which means the answer differs between two businesses with identical debt. The second is that the sequencing rewards planning: a settlement negotiated in one taxation year rather than another can meet a very different set of loss balances. If a lender has raised a write-down, the tax position should be modelled before the agreement is signed, alongside whatever corporate tax debt resolution work the arrears themselves require.

08

A shareholder loan is not a business loan

Two arrangements share the word "loan" and behave nothing alike. A bank lending to your corporation is external debt, handled as described above. A corporation lending money to you as a shareholder is a different animal entirely, and it carries a rule with real teeth.

Under subsection 15(2), an amount a corporation lends to a shareholder is generally included in the shareholder's income unless it is repaid within one year of the end of the corporation's taxation year in which the loan was made. That is a longer window than most people expect and a shorter one than most people use. Repaying and immediately re-borrowing does not solve it either, because a series of loans and repayments can be looked through.

Where the loan stays outstanding, there is also an interest benefit to consider based on a prescribed rate that changes quarterly, so the amount is calculated on the periods involved rather than quoted as a single figure.

The direction that owners underuse is the other one. Where the shareholder lends money to the corporation, the corporation can generally deduct interest paid on ordinary principles, and the shareholder reports interest income. That is a legitimate structure with a real cash consequence and it needs documentation to survive review. The mechanics of both directions are set out in our answer on how a shareholder loan is taxed.

09

Interest limitation rules and who they actually touch

Two sets of rules can cap an interest deduction that would otherwise be allowable. Most owner-managed businesses are outside both, but knowing where the edges are stops a nasty surprise as a group grows.

The thin capitalisation rules limit deductible interest where debt owed to specified non-residents exceeds a one-and-a-half-to-one ratio against the corporation's equity. Interest on the excess is denied and treated as a dividend for withholding purposes. This bites on inbound structures — a Canadian subsidiary funded with debt from a foreign parent — rather than on a local business borrowing from a Canadian bank.

The excessive interest and financing expenses limitation, usually shortened to EIFEL, is newer and broader in concept: it restricts net interest and financing expenses to a fixed proportion of tax-adjusted earnings for taxation years beginning after 2023, with a transitional proportion for the first affected years.

It is aimed at large and multinational groups, and it carries exclusions that keep most owner-managed Canadian-controlled private corporations and smaller groups out of it, including a de minimis threshold for a group's net interest expense. If your corporation is part of a group with substantial intercompany debt, or has taxable capital well beyond the small business range, this is worth a specific look rather than an assumption.

Financing a purchase, or renegotiating one?

A professional tax accountant will trace the use of the proceeds, split the interest and fees correctly and tell you what the loan does to this year's return — at a fixed fee agreed before any work starts, and you pay only after the service is delivered.

Interest the CRA will never let you deduct

Some interest is denied outright, and it is worth knowing the list because these amounts often sit in the same general ledger account as deductible interest.

Interest and penalties charged on unpaid income tax are not deductible. Paragraph 18(1)(t) denies them specifically, which means arrears interest on a late corporate balance is a pure cost with no tax relief attached — one of the reasons instalment discipline pays for itself. The same logic applies to penalties for late filing. Our late-filing penalty calculator shows what those amounts build to, and none of it comes back as a deduction.

Interest on money borrowed for personal purposes is not deductible, and personal use inside a business loan taints its own share of the interest. Interest on funds borrowed to contribute to a registered plan is not deductible either. And where the income-earning source that justified a loan disappears — a business sold, an investment that became worthless — the borrowing may continue while the source does not. The Act contains a specific rule that can preserve deductibility in defined circumstances after a source is lost, but it is a rule with conditions rather than a general continuation, so a loan that outlives the asset it financed needs a fresh look.

11

GST/HST on borrowing and on what you buy with it

Lending money is a financial service, and financial services are exempt supplies for GST/HST. Practically, that means no GST/HST on the interest a lender charges you, and no input tax credit to claim on it — there was no tax in the first place. The same is generally true of the fees a lender charges as part of the lending arrangement, though a fee for something that is genuinely a separate taxable service is treated on its own merits.

What the borrowed money buys is a different question, and this is where the recoverable amounts sit. HST paid on equipment, leasehold improvements, professional fees or inventory acquired for use in commercial activity is generally recoverable as an input tax credit in the ordinary way, regardless of whether the purchase was funded from cash flow or from a loan. In Ontario the rate on those purchases is 13 per cent for 2025, and on a substantial financed purchase the credit is a material amount of working capital that the business should be claiming in the right reporting period rather than late.

The timing point is worth stating plainly: the input tax credit belongs to the period in which the tax became payable, so a large financed purchase near a period end deserves attention to which return it lands in. Our GST/HST calculator handles the arithmetic; the allocation question, where a business has both taxable and exempt activities, is judgement and should be documented.

12

Bookkeeping the loan so the return is right

Everything above depends on the books being able to show it. Four entries do most of the work, and they are not difficult once they are set up.

Set up the loan as a liability account at the advanced amount, not as income. Split every payment between principal, which reduces that liability, and interest, which is an expense — the lender's amortisation schedule gives you the split for each payment, and the schedule should live in the file rather than in somebody's memory. Hold financing fees separately so the five-year release is visible and can be picked up in later years by whoever is preparing the return. And keep the evidence of where the proceeds went: the deposit into the business account, and the payments out of it that show the income-earning use.

Reconcile the loan balance to the lender's statement every month, in the same pass as the bank reconciliation. A loan account that drifts from the lender's figure is telling you that payments have been posted wrongly, and the drift compounds until year-end. That monthly discipline is ordinary bookkeeping work, and it is also what makes a lender's next request for statements a five-minute job instead of a fortnight's reconstruction.

Planning tip

Keep the amortisation schedule, the loan agreement and the proof of where the proceeds were spent in one place for the life of the loan. Those three documents answer almost every question the CRA could ask about the interest deduction, years after the people involved have moved on.

What a lender asks for, and why the numbers must tie

Financing decisions are made on documents, and the documents are the ones your bookkeeping produces. A lender will typically want two or three years of financial statements, the most recent corporate tax return, recent bank statements, an aged receivable and payable listing, and often a forward view of cash flow. The single thing that slows an application down more than any other is a set of statements that does not reconcile to the tax return filed for the same year.

That is a solvable problem. Statements prepared as a compilation engagement carry a note describing the basis on which they were prepared, which is what a lender is reading for, and the trial balance behind them should tie to the schedules filed with the T2. Where a business has been running on internally produced numbers, having a compilation engagement prepared before the application is usually faster than answering questions about inconsistencies afterwards.

Owners searching for small business loan assistance and tax implications in Toronto are usually asking two questions at once: will a lender advance the money, and what will the loan do to the return. They are separate problems with one shared answer, which is books that reconcile.

The Toronto lending market makes this concrete. Businesses across the city — construction and trades in particular, where progress billings and holdbacks complicate the picture — are asked for exactly this package, and the ones that get through underwriting quickly are the ones whose books were already reconciled monthly.

Sector context helps here too: the working-capital cycle in construction is not the one a lender expects from a professional services firm, and statements that explain the cycle on their face get fewer questions. For businesses across the region, our Toronto tax accountant team handles the statement-and-return package end to end, remotely, anywhere in Canada. Where the ask is straightforward corporate compliance, the fixed-fee corporate tax filing price is published rather than quoted on request, and the fee is agreed before work begins.

One more forward-looking point. A lender is assessing whether the business can service the debt, which is a cash flow question rather than a profit question, and the two differ precisely because principal repayment is not an expense. A business can be profitable and still fail a debt service test, because the principal has to come out of after-tax cash.

Modelling that before you borrow — what the payment does to monthly cash, and what the tax bill looks like once only the interest is deductible — is the difference between debt that funds growth and debt that quietly consumes it. Our break-even calculator is a reasonable starting point for the cash side.

Frequently asked questions

Is a business loan taxable income in Canada?

No. Loan proceeds are a liability, not revenue, so receiving the money does not create taxable income and it is not reported as income on the corporate return. The consequence of that treatment is that repaying the principal is not deductible either. Only the interest, and certain financing costs, reduce taxable income.

Can I deduct the whole loan payment as a business expense?

No. Each payment has to be split. The interest portion is generally deductible where the borrowed money was used to earn business or property income; the principal portion simply reduces the loan balance and is never an expense. Your lender's amortisation schedule gives the split for every payment.

Is interest deductible if I secured the business loan against my house?

Deductibility follows the use of the money, not the security. If the proceeds were used in the business to earn income, the interest is generally deductible even though the security was residential. Keep evidence of where the funds went, because that tracing is what supports the claim if it is ever questioned.

Why can't I deduct the loan arrangement fee this year?

Most costs incurred in the course of borrowing money are deductible over five years rather than immediately, under paragraph 20(1)(e). The deduction is not lost, only spread. Where the loan is repaid early, the unamortised balance can generally be claimed in the year the obligation ends.

Is a forgivable government loan taxable?

The forgivable portion is generally treated as government assistance and included in income under paragraph 12(1)(x), often in the year it is received rather than the year forgiveness is confirmed. An election under subsection 12(2.2) can instead reduce the cost of the related property or expense. Which is better depends on what the money funded, and the election has to be made on a filed return.

What happens for tax if a lender writes off part of my loan?

Section 80 applies to the settlement of commercial debt. The forgiven amount is applied against loss balances in a prescribed order, and where those run out part of it can end up in income, with some relief available by reserve or election. Because the outcome depends on the balances your corporation already has, model it before signing a settlement.

Can I deduct interest the CRA charged me on unpaid tax?

No. Paragraph 18(1)(t) denies a deduction for interest and penalties charged on income tax, so arrears interest is a pure cost with no tax relief attached to it at all. That is different from interest on a commercial loan, which is generally deductible. It is also why staying current on instalments is worth more than it looks: every dollar of arrears interest is paid with after-tax money and never comes back.

Do I pay GST/HST on business loan interest?

No. Lending is a financial service and exempt for GST/HST, so there is no tax on the interest and nothing to recover on it. The HST on what you buy with the loan is a different matter and is generally recoverable as an input tax credit where the purchase is for use in commercial activity — 13 per cent in Ontario for 2025.

Is a loan from my own corporation treated the same way?

No, and the difference is significant. Under subsection 15(2) a loan from the corporation to a shareholder is generally included in the shareholder's income unless it is repaid within one year of the end of the corporation's taxation year in which the loan was made, and an interest benefit may apply while it is outstanding. It is not interchangeable with third-party business debt.

Does taking on debt affect my small business deduction?

Borrowing itself does not. What can affect the small business deduction is what the business does with the money: passive investment income earned inside the corporation, and the size of the corporation's taxable capital, both interact with the deduction. If a loan is funding investments rather than active business assets, the interaction is worth checking before rather than after.

Fixed fees, no hourly billing Pay after service 900+ social reviews

Debt is a tool, and like most tools its tax treatment is unforgiving of guesswork. The rules themselves are stable: principal is neither income nor a deduction, interest follows the use of the money, financing fees are spread across five years, forgivable assistance is income before it feels like it, and a settlement works through your loss balances rather than around them.

What varies is the business — what the money bought, where it went, which year it landed in, and whether the books can show any of it. Decide those questions while the loan is being arranged and the return almost writes itself; leave them until filing season and you are reconstructing evidence for a deduction you already earned.
