You issued a tax invoice and discovered an error in the amount, or the client canceled the transaction right after it was sent? It happens to everyone. The problem is that once a tax invoice is issued, a tax event is created: its VAT goes into the VAT report for the period in which it was issued and is paid with it, even if the client hasn't paid you yet. Canceling an invoice outside the rules is not just a bookkeeping issue: it can make your books non-compliant, and canceling one to evade tax is a criminal offense.
Key Takeaways
- You cannot delete an issued tax invoice: you cancel or correct it with a credit invoice that states the original invoice's number and date and the reason for the change. An unpaid transaction invoice (payment request) can usually just be marked as canceled, and the document is kept.
- A tax invoice puts its VAT into that period's VAT report even if the client hasn't paid, and the VAT stays payable until the invoice is corrected, usually with a credit invoice. Only an Osek Murshe may issue tax invoices, so this process does not apply to an Osek Patur.
- A credit invoice fits a wrong amount (credit it and issue a new invoice), a canceled deal or returned goods (credit the refund, minus any cancellation fee you keep) and a discount agreed after invoicing (credit the discount only).
- If the original invoice already reached the client, you can reduce the VAT you reported only with proof that the client received the credit invoice, such as their signature on your copy or registered mail with delivery confirmation.
- Registered invoicing software does not let you delete an issued tax invoice. It keeps the numbering unbroken and records every correction as a further document, such as a credit invoice that references the original.
The First Rule: Critical Difference Between Document Types
Before diving into cancellations, you must understand the fundamental difference between document types. Confusion between them is the source of most mistakes freelancers make.
Transaction Invoice (Payment Request): A document that does not by itself create a tax event. It's simply a payment request. If you issued a transaction invoice and the client didn't pay or the deal was canceled, you can mark it as canceled in the system: the document itself is kept and the numbering stays unbroken. For most small service providers, VAT arises only when payment is received, so canceling it has no VAT effect. Where VAT arises on delivery, for example when a larger business sells goods, canceling the document does not cancel the liability. The method is common among Osek Murshe service providers, who issue the tax invoice only once payment arrives.
Tax Invoice: This is the binding document, and only an Osek Murshe may issue one. The moment you issue it, you've declared to the state that a transaction occurred and that you're obligated to remit VAT on it. The amount also counts toward the turnover your income tax advances are calculated on, if your advances are set that way. This document cannot be "deleted," "shredded," or made to disappear. The usual way to handle it is through a counter-document - a credit invoice.
If you are an Osek Patur, the credit-invoice rules in this article do not apply to you: you issue receipts, and sometimes a transaction invoice as a payment request, but never a tax invoice that would need a credit. A receipt issued in error is not deleted either: in invoicing software it is canceled with a further document, and the original stays on file.
When Can You Issue a Credit Invoice?
A credit invoice is the usual legal way to cancel the effect of a tax invoice that was issued in error or whose transaction basis was canceled. Here are the main scenarios:
- Clear clerical error: You issued an invoice for 10,000 NIS instead of 1,000 NIS by mistake. If the error was discovered immediately, issue a credit invoice for the incorrect amount and generate a new, correct tax invoice.
- Transaction cancellation and product returns: The client returned the product, or the service was canceled before delivery. Note: if you charged cancellation fees, the credit invoice should be for the original amount minus the cancellation fees collected.
- Retroactive commercial discount: You agreed on a discount with the client after the original invoice was issued. Issue a credit invoice for the discount amount only.
Critical technical detail: Under the Income Tax (Bookkeeping) Instructions, the credit invoice must state, among other details, the number and date of the original invoice and the reason for the change in the amount. Issuing a "generic" credit without justification may be considered non-compliance with proper bookkeeping regulations.
Before issuing a credit invoice, check what exactly is wrong. A discount agreed afterwards needs a credit for the discount amount only, while a wrong amount, including one that is too low, is usually fixed by crediting the wrong invoice and issuing a new, correct one. A credit invoice can never be larger than the original invoice it refers to.
The Pitfall: Invoice Already Sent to the Client
Things get complicated when the original tax invoice has already been sent to the client. In this case, there's concern that the client already used the invoice to offset input VAT for themselves.
For a credit invoice to reduce the VAT you reported, you need proof that the client received it. This applies to every client, private or business. A VAT-registered client must, for its part, reduce its input tax deduction in the period it receives the credit invoice.
The Bookkeeping Instructions list four ways to prove receipt: the client's signature on the copy you keep, registered mail with delivery confirmation, a fax receipt confirmation, or a receipt confirmation signed with the client's certified electronic signature. An automatic send log in invoicing software helps document delivery, but it is not one of those four.
Store the proof with your copy of the credit invoice, since it is what supports the VAT reduction if your VAT file is audited. Registered mail counts as proof only when it is sent with delivery confirmation, and when the VAT on the original sale is above 1,400 NIS (as of September 2026), that confirmation must also be attached to your copy.
Summary Table: When and How to Cancel?
| Scenario | Document Type | Can You Cancel? | Required Action |
|---|---|---|---|
| Amount error before sending | Transaction invoice | Yes, easily | Mark as canceled (the document is kept), issue a new one |
| Amount error before sending | Tax invoice | Yes, mandatory | Issue credit invoice and new tax invoice |
| Transaction canceled after sending | Tax invoice | Yes, mandatory | Credit invoice (minus cancellation fees), send to client |
| Client didn't pay (bad debt) | Tax invoice | Very complex | Requires proof the debt cannot be collected (collection efforts, sometimes legal proceedings) and a notice to the VAT office |
| Attempt to evade tax | Tax invoice | Absolutely prohibited | Criminal offense of income concealment |
The bad-debt row has a time window: the credit invoice and a written notice to the VAT office can be filed no earlier than 6 months and no later than 3 years after the invoice date. Time spent in the client's bankruptcy or liquidation proceedings, or between filing a collection lawsuit and a final judgment, is not counted toward the 3 years.
The Digital Era and the "Israel Invoices" Model
In a manual invoice book, a tax invoice that has not left the business and has not been reported is canceled by writing "canceled" on the original and every copy and keeping them together. Tearing the documents up was never allowed. In a computerized system even that option is gone: an issued tax invoice is corrected only with a further document, usually a credit invoice.
Modern digital invoice systems prevent you from performing illegal actions like deleting an issued tax invoice. They require you to go through the proper process of issuing a credit invoice, creating a clear link between the credit document and the source document.
Furthermore, under the new model, a tax invoice to an Osek Murshe client above 5,000 NIS before VAT (as of September 2026) needs an allocation number from the Tax Authority's system. It is usually requested when the invoice is issued, but can also be requested afterwards. Without it, the client cannot deduct the input VAT. The Tax Authority therefore receives these invoices' details when the number is requested, and it can refuse an allocation number when it suspects a fictitious invoice.
The allocation-number threshold has dropped in steps: 20,000 NIS before VAT in 2025, 10,000 NIS from January 2026 and 5,000 NIS from June 2026. If you issue tax invoices to businesses, check that your invoicing software requests the number whenever an invoice is above the current threshold.
Staying Organized, Avoiding Complications
Proper handling of cancellation documents is a critical part of running a healthy business. Tax authorities view irregularities in income recording and unjustified invoice cancellations very seriously.
A simple way to avoid mistakes is to work with an organized system that guides you through legal actions and prevents you from performing prohibited ones.
In Keep, canceling a tax invoice issues a credit invoice, on every plan, as part of issuing income documents. The recommended plan also includes a personal accountant for professional guidance and representation before the tax authorities.
Check the amount, the client's details and the VAT before you issue a tax invoice, not only before you send it: in invoicing software even an unsent tax invoice cannot be deleted, only corrected with a further document, usually a credit invoice. Errors that are not about the amount, such as the wrong client or a duplicate invoice, are usually fixed the same way: a credit invoice for the full amount of the wrong invoice and, where needed, a new correct one.
Frequently Asked Questions About Canceling an Invoice
Can you delete a tax invoice issued by mistake?
No. An issued tax invoice stays in your books. If it contains an error or the deal was canceled, you issue a credit invoice that references the original and states the reason, and then a new, correct invoice if needed.
What is the difference between canceling a transaction invoice and a tax invoice?
A transaction invoice is a payment request and does not by itself create a tax event, so an unpaid one can usually be marked as canceled while the document stays on file. A tax invoice creates a VAT liability, so it is corrected with a credit invoice, never deleted.
When do you need to issue a credit invoice?
When a tax invoice has already been issued and its effect has to be corrected or canceled: a wrong amount, a canceled deal, returned goods or a discount agreed afterwards. Late payment on its own is not one of these reasons.
Do you have to send the credit invoice to the client?
Yes, if the original invoice has already left your business. To reduce the VAT you reported, you need proof that the client received the credit invoice, whether the client is a private person or a business.
What if the client simply never paid the invoice?
Non-payment alone is not a reason to issue a credit invoice. If the debt becomes bad, a separate VAT procedure lets you reduce the VAT: you show that the debt cannot be collected (collection efforts, sometimes legal proceedings), then issue a credit invoice and file a notice with the VAT office. This is done between 6 months and 3 years after the invoice date.
