Receiving Is an Obligation Too: Deduction and Fines Since 1 April 2026

You spent a year making sure your invoices leave in the right format. Nobody rehearsed the other direction: the invoices arriving.

Since 1 January 2026 a Belgian business that buys from another Belgian business has to be able to receive a structured electronic invoice, not only send one. That half of the obligation attracted almost no attention, because sending is visible — you can watch an invoice go — and receiving is not. An invoice that never arrives produces no error message, no bounce, and no complaint until a supplier calls about a payment.

The window in which "we are getting there" was an answer has closed.

The dates that still matter

The obligation took effect on 1 January 2026, together with the Royal Decree that sets the penalties. A general tolerance meant no penalties were applied until 31 March 2026. From 1 April 2026, they are possible.

There was one further reprieve after that, but it was narrow: it covered self-billing arrangements only, and it ran out on 30 June 2026. It is quoted in practice far more often than it deserves, usually by someone who believes it bought them another quarter. It did not. If you are working from that date, you are working from the wrong one.

The fine is for not being able to, not for getting it wrong

This is the part most people have backwards. The penalty in the Royal Decree is not charged per invoice and it is not charged for a badly formatted document. It attaches to not having the technical means to issue and receive structured electronic invoices at all — the equivalent of a business that never installed the till it was required to have.

The amounts are €1,500, then €3,000, then €5,000.

There is a detail inside that escalation worth knowing, because it is genuinely in your favour. A later breach only counts as a repeat if it is established at least three months after the previous one. Three findings in the same audit are not €1,500 plus €3,000 plus €5,000. An inspector cannot climb the ladder inside a single visit.

That is a real defence, and it is the reason the honest advice is fix it now rather than panic. The exposure is bounded. What is not bounded is how long it stays unfixed.

The supplier PDF sitting in your inbox

Here is the sentence that makes bookkeepers uncomfortable, and it deserves to be said precisely rather than dramatically.

For a purchase that is covered by the obligation, the tax administration's own guidance says the right to deduct the VAT rests on holding a structured electronic invoice. A PDF from the supplier is, in principle, not the document that supports that deduction.

"In principle" is doing real work in that sentence, and so is "covered by the obligation". Neither of them is a technicality.

It is not money gone. Belgian VAT doctrine holds that where the substance is right — the purchase happened, it was for the business, the VAT was genuinely due — a deduction is not refused because a document has the wrong form. Treat a supplier PDF on an in-scope purchase as a flag to chase, not as a loss to book. What it actually costs you is the chase: writing to a supplier four months later to ask for the same invoice again, and doing that across a year of purchases at once instead of one at a time.

And not every PDF is a problem. A change in the law in February 2026 kept the lawful PDF alive in two situations. If your supplier is not established in Belgium, they are no longer obliged to issue you a structured invoice at all. And if the customer genuinely cannot receive one technically, the supplier is not obliged to issue one either and must issue an ordinary invoice instead — an ordinary invoice being a perfectly normal invoice that supports deduction in the perfectly normal way. A client buying from a Dutch or German supplier and booking the PDF has done nothing wrong.

So the question to ask about any PDF in the file is not "is this legal", it is "was this purchase in scope, and if it was, why did it come as a PDF".

The asymmetry nobody points out

Read that carve-out from both ends and something uncomfortable appears.

If your customer cannot technically receive a structured invoice, you are discharged. You send them an ordinary invoice, and you are compliant.

If you cannot receive one, nothing discharges you. The relief was written for the person sending, not for the person who was not ready. The obligation to have the means is yours, and no supplier's flexibility cures it.

That asymmetry is the whole argument for treating receiving as its own project rather than as a side effect of having sorted out sending.

Sending working does not mean receiving works

The most common failure in Belgium right now is not a rejection. It is silence.

Peppol routes invoices to a participant identifier. Belgium identifies its participants by enterprise number. Some businesses were registered years ago under an older identifier based on the VAT number instead, and were never migrated. An invoice addressed to the identifier a supplier assumes you use is simply never delivered — and, because nothing was rejected, nobody is told. Not the supplier, not you.

Nothing about your outgoing invoices leaving successfully tells you anything about this. They are different capabilities, with different registrations and different failure modes. Watching your sales invoices depart and concluding you are ready is the single most common mistake being made on this file.

Four things to do this month

• Ask your bookkeeper or your provider one question: is our Peppol receiving live, and on which identifier. Not "are we on Peppol". The identifier.
• Have someone send you a real invoice. A live test to your own identifier, and confirmation that it landed where your books are kept — not a screen that says no error occurred.
• Ask what happened to supplier PDFs booked since January. You want a list, not a reassurance. If the list is short, the problem is small and worth closing today.
• If a Belgian supplier keeps sending you PDFs, ask why. Either they are not ready, or they think you are not — and the second answer is the one that costs you.

What ignoring it actually costs

Not a catastrophe. A slow, compounding, entirely avoidable mess: invoices you never received and therefore never paid, suppliers chasing you for money you did not know you owed, a year of deduction flags to reopen with counterparties who have moved on, and a penalty that starts at €1,500 and can grow every three months you leave it alone.

None of that is dramatic. All of it is the kind of thing that surfaces in the worst week of the year.

The fix is an afternoon. Confirm the identifier, receive one real invoice, and check the file.
