Invoice Allocation Numbers: The Full Business Guide

Category: VAT & Reporting | Reading time: approx. 7 minutes

The "Israel Invoices" model is one of the Tax Authority's most significant moves of the past decade, designed to fight a phenomenon that cost the state billions of shekels a year: fictitious invoices — invoices issued with no real transaction behind them, used to unlawfully deduct input VAT. The chosen solution is simple in principle and far-reaching in its consequences: above the statutory threshold, a tax invoice between dealers entitles the customer to an input VAT deduction only if it received an "allocation number" from the Tax Authority in advance.

What Is an Allocation Number and How Does It Work?

An allocation number is a nine-digit number issued by the Tax Authority's system for each specific tax invoice, in real time, before it is issued. In practice, the process is nearly transparent for those set up correctly:

• In connected accounting and invoicing software — the software sends the invoice details to the Tax Authority's server at the moment of issuance, receives the allocation number back, and it is printed automatically on the invoice. A few seconds;
• For those without connected software — an allocation number can be requested manually in the personal area on the Tax Authority website, but this is a cumbersome route unsuitable for a business with ongoing activity;
• The customer (invoice payer) can verify the invoice with the Tax Authority and confirm that the allocation number is genuine and matches the details.

The Thresholds: A Gradual Descent — Today Almost Everything Is In

The model was applied gradually, with the threshold (invoice amount including VAT) dropping year by year:

• May 2024 (model launch): invoices above NIS 25,000;
• 2025: above NIS 20,000;
• From January 1, 2026: above NIS 10,000;
• From June 1, 2026: above NIS 5,000 — the current threshold.

The meaning: if at first the model touched mainly large transactions, today — with a NIS 5,000 threshold — it applies to the vast majority of business-to-business transactions in the economy. A business that has not yet prepared simply cannot function with business customers.

Who Does It Apply To — and Who Not?

• Required: authorized dealers, companies and partnerships issuing tax invoices above the threshold to business customers seeking to deduct input VAT;
• Exempt dealers — do not issue tax invoices at all, so the model does not apply to them;
• Transactions with private consumers — the consumer does not deduct VAT, so there is no practical need for an allocation number;
• Invoices below the threshold — do not require an allocation number (though one may be requested for them too, and some software does so automatically for every invoice).

What Happens Without an Allocation Number?

Here lies the model's "whip", and it is aimed at the customer: a tax invoice that requires an allocation number and lacks one — does not entitle the customer to an input VAT deduction. In other words, your business customer loses the VAT they paid you (18%!) if you fail to provide an invoice with a lawful allocation. The practical result in the field: business customers simply refuse to pay invoices without an allocation number, and an unprepared supplier finds itself with a collection and cash-flow problem. On your side as a customer — make sure every supplier invoice above the threshold carries an allocation number, or your input deduction is at risk.

What If the Tax Authority Refuses to Allocate?

This is the heart of the model from the Tax Authority's perspective: it may decline to allocate a number where there is a real concern the invoice is being issued unlawfully (suspected fictitious invoice). In such a case:

• The request moves to review, and the dealer is invited to a fast clarification and hearing process — documents proving the genuineness of the transaction can be presented (agreement, delivery notes, correspondence, payment evidence);
• A final refusal decision can be objected to and appealed through the statutory channels;
• Important to know: for legitimate businesses refusal is rare — but when it happens, it stops the transaction on the spot, so immediate professional handling is required.

An allocation refusal is also a warning sign: it indicates the business has been flagged in the Authority's risk-analysis systems. In that situation it is worth reviewing the full picture with your CPA — before the matter rolls into a comprehensive audit.

How to Prepare? A Checklist

1. Make sure your invoicing software is connected to the Tax Authority's allocation system and up to date — all leading platforms support it, but an active authorization is needed;
2. Arrange access permissions — connection requires the business's digital identification with the Tax Authority, including a power of attorney for the software or the representative;
3. Implement supplier-invoice checking — every incoming invoice above the threshold must carry an allocation number; otherwise do not deduct input VAT on it before clarification;
4. Watch out for split transactions — artificially splitting a deal into several invoices below the threshold to avoid allocation is an invitation for trouble;
5. If you received a refusal or clarification demand — do not ignore it and do not go alone: orderly documentation of the transaction and professional accompaniment at the hearing are the difference between quick approval and a stuck deal.
