When a Client Never Pays: The Bad Debt Write-Off
An unpaid invoice hurts twice. You did the work for nothing — and if you're like most Canadian freelancers, you already reported that invoice as income and paid tax on money you never received. The bad debt deduction is the tax system's partial remedy: when a receivable genuinely goes uncollectible, you deduct it, reversing the income you reported, and you can usually recover the GST/HST you remitted on it too. But the write-off has conditions, a documentation standard, and a common trap that catches cash-basis thinkers. This guide walks through when an unpaid invoice becomes deductible, how to claim it on T2125 line 8590, how the GST/HST adjustment works, and — because a deduction only ever recovers a fraction of the fee — the invoicing habits that prevent bad debts in the first place.
Why an Unpaid Invoice Is Deductible at All
The logic starts with how freelance income is counted. Under accrual accounting — the default for most self-employed Canadians — an invoice becomes income when you issue it, not when it's paid. The subtotal of every invoice you issued during the year goes into Line 8000 of your T2125, paid or not. Our line-by-line T2125 guide covers that mechanic in detail.
That rule usually works in your favour at collection time and against you when a client vanishes: you've paid income tax (and possibly remitted HST) on revenue that never arrived. The bad debt deduction restores the balance. When a receivable is established to be uncollectible, you deduct the unpaid amount on T2125, Part 4, line 8590 — Bad debts, cancelling out the income you reported earlier.
Seen this way, the write-off isn't a bonus deduction. It's a correction: the income turned out not to exist, so the tax on it shouldn't either.
The Two Conditions
A bad debt claim stands on two legs, and the CRA expects both:
| Condition | What It Means in Practice |
|---|---|
| 1. The amount was included in your income | The invoice's subtotal went into Line 8000 in this year or a previous year. Work you never invoiced, or amounts you never reported, don't qualify. |
| 2. The debt became uncollectible in the year you claim it | You made a genuine determination — supported by evidence — that the client will not pay. Overdue is not the same as uncollectible. |
The first condition is the trap for freelancers who think in cash terms. If you never counted the invoice as income, there is nothing to write off — deducting it anyway claims the same loss twice. The second condition is a judgment call, but it must be a documented judgment call made in the year of the claim, not a shrug.
What "Established Uncollectible" Actually Looks Like
The CRA doesn't publish a checklist, but the pattern that survives review is consistent: a receivable that aged past its terms, followed by escalating and documented collection attempts, ending in a reasonable conclusion that further pursuit is futile. In practice:
- Dated payment reminders — the polite follow-up sequence every freelancer should run anyway. Our guide on following up on unpaid invoices lays out the cadence.
- A formal demand letter — a dated, written demand for payment with a deadline, sent once reminders fail.
- Escalation you genuinely considered or pursued — a collection agency, small claims court, or a documented decision that the amount doesn't justify the cost of either.
- Evidence about the debtor — the client's business closed, they filed for bankruptcy or a consumer proposal, they've become unreachable, or a dispute made recovery realistically impossible (see what to do when a client disputes your invoice).
Timing matters: the deduction belongs to the year in which you established the debt was bad — which is not necessarily the year the invoice was issued. An invoice from November that goes bad the following June is a deduction in that following year.
A write-off claimed the week an invoice went overdue, with no collection trail behind it, is the version that gets denied. The paper trail is the claim.
The GST/HST Side: Recovering Tax You Remitted
If you're GST/HST-registered, an unpaid invoice stings a third time: you likely remitted the tax on it to the CRA even though the client never paid you. The system provides a remedy here too — the bad debt adjustment.
In general terms: where you reported and remitted the GST/HST on a supply, and the receivable has since been written off as a bad debt in your records, you can claim an adjustment on a GST/HST return to recover the tax you remitted but never collected. Take a $2,260 Ontario invoice — $2,000 fee plus $260 HST — that goes bad after you remitted the $260:
$2,000 deduction on line 8590 + $260 recovered on your GST/HST return
Two caveats. The adjustment has conditions and time limits, so verify the current mechanics on canada.ca or with your accountant before claiming. And it's symmetrical: if the client later pays, you add the corresponding tax back on a future return, just as the recovered fee goes back into income. For how adjustments fit into your filing rhythm, see the quarterly GST/HST remittance guide.
Partial Payments, Settlements, and Later Recoveries
Partial Payments
If a client paid $1,500 of a $4,000 invoice and then went silent, only the unpaid $2,500 is a candidate for the write-off. The collected portion stays income, as it should.
Negotiated Settlements
If you settle — the client pays $2,000 to close out a $4,000 invoice — the forgiven $2,000 remainder is generally deductible as a bad debt once the settlement is final, with the settlement agreement itself serving as the documentation.
When a Written-Off Debt Gets Paid
Recoveries happen — a client resurfaces a year later with a conscience or a solvent business. A recovered bad debt is income again in the year you receive it, reported as other income on line 8230. You don't amend the old return; the correction runs through the current year.
A Note on Cash-Basis Reporting
A small number of self-employed people report on a cash basis (certain farmers and fishers, under specific rules). If income only counts when received, an unpaid invoice never entered income — so there is no bad debt to deduct. For nearly all freelancers, contractors, and consultants, accrual applies and the write-off is available.
Prevention Beats the Deduction — Every Time
Keep the write-off in perspective: a $4,000 bad debt deduction saves you perhaps $1,200–$1,800 of tax depending on your marginal rate. You still lost the rest of the fee and every hour of the work. The deduction is a consolation prize, and the better game is not needing it:
- Deposits on new clients and large projects — money up front is the single strongest bad-debt vaccine. See our deposit invoice guide.
- Clear, short payment terms — the longer the window, the colder the debt. Our payment terms guide covers choosing terms by client type.
- Late fees stated on every invoice — a stated 1.5%/month charge changes payment priority even when you never enforce it.
- Follow up early and on schedule — receivables that get chased in week one rarely become write-offs in month twelve.
Frequently Asked Questions
Can I write off an unpaid invoice on my taxes?
Yes — if the amount was already included in your income and you've established during the year that it's genuinely uncollectible, it's deductible as a bad debt on T2125 line 8590. Overdue alone isn't enough; document your collection attempts first.
Can I write off an invoice I never reported as income?
No. The deduction only reverses income you already reported. If the invoice never entered Line 8000 — unbilled work, or income counted on a cash basis and never received — there's nothing to reverse, and claiming it anyway double-counts the loss.
Can I get back the HST I remitted on an unpaid invoice?
Generally yes, through a bad debt adjustment on a GST/HST return, once the receivable is written off in your records. Conditions and time limits apply — verify current rules before claiming — and if the client later pays, the tax goes back on a future return.
What happens if the client pays after I've written it off?
The recovered amount becomes income again in the year you receive it (line 8230, other income), and any recovered GST/HST is added back on a future GST/HST return. You don't amend the year of the write-off.
How long should I wait before writing off an invoice?
There's no fixed waiting period — the standard is a genuine, documented determination that the debt is uncollectible, made in the year you claim it. In practice that usually means months of escalating collection attempts, or clear evidence like the client's insolvency. Judgment plus paper trail, not a calendar rule.
