In Canada, if a client goes bankrupt and fails to pay your invoice, you can claim a ‘bad debt’ deduction to legally reduce your taxable business income. You must keep the Licensed Insolvency Trustee’s Notice of Bankruptcy as proof for the CRA. As of June 2026, you can also recover the GST/HST you already remitted on that unpaid invoice.
Running a small business in Canada takes immense dedication, and unpaid invoices are a major threat to your cash flow. Whether you operate a marketing agency in Halifax, a logistics firm in Winnipeg, or an IT consultancy in Montreal, a client filing for bankruptcy can leave you with thousands of dollars in uncollectible receivables.
Many business owners mistakenly believe they simply have to swallow the loss. Fortunately, the Canada Revenue Agency (CRA) provides a mechanism to soften the blow. When a debt becomes truly uncollectible due to a formal insolvency proceeding, you can write it off as a bad debt, significantly lowering your corporate or personal tax burden for the year. 💰
However, the CRA is strict about what qualifies as a bad debt. You cannot simply guess that a client will not pay. You need concrete, legal documentation from the federal bankruptcy system. Working alongside a certified accountant is highly recommended to ensure you claim this deduction flawlessly.
Step-by-Step Process for Claiming a Bad Debt in Canada
Turning a lost invoice into a tax advantage requires proper accounting. Generally, Canadian tax law requires you to follow these exact steps to satisfy CRA auditors. 📊
Step 1: Obtain the Notice of Bankruptcy
To prove the debt is dead, you need official evidence. When your client files for bankruptcy, their Licensed Insolvency Trustee (LIT) will mail you a Notice of Bankruptcy. Keep this document securely in your corporate minute book or accounting files.
Step 2: File Your Proof of Claim
Even though you are writing off the debt, you should still file a Form 31 Proof of Claim with the LIT. This ensures that if the bankrupt estate miraculously pays a tiny dividend to unsecured creditors three years from now, you will receive your share. 📝
Step 3: Calculate the Net Income Deduction
Identify the exact pre-tax amount of the unpaid invoice that you previously reported as income. Because you operate on an accrual accounting basis, you already paid tax on this ‘phantom’ money. You will deduct this exact amount from your current year’s gross business income.
Step 4: Calculate the GST/HST Adjustment
If you already sent the CRA the GST or HST for that unpaid invoice, you are entitled to get it back. You must calculate the exact tax portion of the bad debt and claim it as a deduction on your next regular GST/HST return.
Step 5: File Your Annual Tax Return
When tax season arrives, your accountant will enter the bad debt deduction on your T2 Corporate Income Tax Return (or your T1 if you are a sole proprietor). This directly reduces your net taxable income, lowering your overall tax bill.
Step 6: Retain Records for Six Years
The CRA frequently audits bad debt claims. You are legally required to keep the original unpaid invoices, the client communications, and the LIT’s bankruptcy documents on file for a minimum of 6 years from the end of the tax year.
Bad Debt vs. Allowance for Doubtful Accounts
Accounting for missed payments happens in two distinct stages. Here is how the CRA views the difference between a struggling client and a bankrupt one:
| Accounting Term | CRA Treatment & Proof Required |
|---|---|
| Allowance for Doubtful Accounts | Used when a client is heavily delayed (e.g., 90+ days late) but still operating. You can claim a temporary reserve, but you must constantly reassess if they might still pay. |
| Bad Debt Expense (Write-Off) | Used when the debt is 100% uncollectible (e.g., formal bankruptcy or company dissolved). It is permanently removed from your accounts receivable and fully deducted from income. |
How Much Does it Cost in Canada?
Managing bad debts and adjusting your tax returns involves administrative and professional expenses. As of June 2026, small businesses should budget for the following:
- CRA Processing Fees: Claiming a bad debt deduction on your T2 or adjusting your GST/HST return is $0. The CRA does not charge fees to file standard returns.
- OSB Search Fee: If a client ghosts you and you need to check if they filed for bankruptcy, searching the federal OSB database costs $8 CAD per name.
- Accountant (CPA) Fees: Having a professional accountant handle complex bad debt write-offs and GST adjustments typically costs between $300 CAD and $1,000 CAD depending on the volume of invoices.
- Collection Agency Fees: If you try to collect *before* they file bankruptcy, agencies usually take 20% to 40% of whatever money they successfully recover.
How Long Does the Process Take?
You can claim the bad debt deduction in the exact tax year that the debt is formally recognized as uncollectible (the year you receive the Notice of Bankruptcy). Adjusting your GST/HST can be done on your very next monthly or quarterly filing. If you are filing an amendment for a previous year’s tax return because you forgot to write it off, the CRA typically takes 2 to 8 weeks to issue a Notice of Reassessment and refund your overpaid taxes.
Frequently Asked Questions (FAQ)
What if the bankrupt client pays me a dividend later?
If the Licensed Insolvency Trustee sends you a small dividend cheque two years from now, you simply declare that exact amount as ‘recovery of bad debt’ income in the year you receive it.
Can I write off unbilled time or unworked hours?
No. You can only claim a bad debt deduction for amounts that were previously invoiced and officially included in your business income. You cannot write off the ‘potential’ value of unbilled labour.
Does a Consumer Proposal count for a bad debt?
Yes. If your client files a Consumer Proposal or Division I Proposal and you agree to accept only 30% of the invoice, the remaining 70% that is legally forgiven becomes an eligible bad debt deduction.
Do I need a lawyer for this?
Writing off a debt is primarily a tax issue best handled by a CPA. However, if the client is hiding assets to avoid paying, browse our directory to find a Canadian debt recovery lawyer to investigate further.
