When and How to Write Off an Unpaid Invoice

Some invoices die. The client vanished, the company folded, or the balance is too small to justify a fight. Writing off an unpaid invoice is how you formally stop counting that money as coming, so your books describe reality instead of hope. It stings, but done at the right moment it frees up hours you were burning on a lost cause, and done correctly it keeps your records and your taxes clean.

When an Invoice Crosses the Line

There's no official day an invoice becomes bad debt, but the signals converge: it's 90 or more days past due and a full reminder sequence has produced nothing, the client is unreachable or the business has dissolved, the amount is disputed and you've decided the fight costs more than the balance, or collections and small claims would eat most of what you'd recover. Run the cheap plays first. Reminders, a phone call, and a settlement offer at 50-70% resolve a surprising number of standoffs, and the full escalation path is in what to do when a client won't pay. Write off what's left after real effort, not instead of it.

The Tax Part Most Freelancers Get Wrong

Here's the catch: you can generally only deduct a bad debt if you already counted that invoice as income. Most freelancers and small service businesses use cash basis accounting, meaning income is recorded when money arrives. An unpaid invoice never became income, so there's nothing to deduct; you simply never report money you never received. The real out of pocket costs of the job, like materials you bought, are still deductible as ordinary business expenses. Accrual basis businesses, which record income at invoicing, may be able to claim a genuine bad debt deduction. Rules differ by country and situation, so have an accountant confirm how this applies to you before you touch your return.

How to Record the Write Off

1. 1Send one final demand, in writing, stating the amount and a last response date. It closes the loop and documents your effort.
2. 2Mark the invoice as written off in your records, with the date and a one line reason. Don't delete it, and don't void it; voiding is for invoices that were mistakes, as covered in how to void an invoice. This invoice was real. It just won't be paid.
3. 3File the evidence of your collection attempts alongside it: reminder emails, call notes, the final demand.
4. 4On accrual books, record the bad debt expense against receivables. On cash books, no income entry changes; you're just updating your own tracking so the balance stops appearing in money you're owed.
5. 5Keep the invoice and notes for your normal retention period, since written off does not mean erased.

You Can Still Collect Later

A write off is internal bookkeeping, not forgiveness. The client still owes the money, and if they resurface next year with a conscience or a lawsuit scare, you can absolutely accept payment; you'd record it as income when it arrives. Collections and small claims remain open options until your state's limitations period runs out. If you decide to genuinely forgive the debt, that's a separate step: say so in writing and stop pursuing it. Just don't tell a client you've written it off casually, because they'll hear forgiveness even when you meant paperwork.

Make the Next One Less Likely

Every written off invoice is tuition, so extract the lesson. Most bad debts trace back to the same handful of causes: no deposit on a new client, exposure that grew unchecked because work continued while invoices aged, and warning signs that were visible on invoice one. Turn your specific loss into a specific rule, like deposits on all new clients or work pauses at 14 days past due, and write the rule down where you'll see it. A write off you learn from costs once. The same write off repeated annually is a pricing problem wearing a disguise.
