Credit Notes for EU Freelancers: When to Issue One (2026)

The rule sounds simple: issued invoices are permanent. But most freelancers only discover this when they need to fix an error — they open the PDF, change the amount, resend it, and assume the problem is solved. It is not. The original invoice still exists in your client's accounting system, in their VAT return, and potentially in a national e-invoicing platform. Here is how to correct it properly.

Why You Cannot Delete or Edit an Issued Invoice

EU VAT law requires sequential invoice numbering with no gaps (Article 226 of Directive 2006/112/EC). Once you issue invoice INV-2026-042, that number is permanently committed. If you delete it and replace it with a corrected document carrying the same number, you have:

1. Created a gap in your invoice sequence (the original, now deleted, was the legally issued document)
2. Altered a document that may already be in your client's VAT records
3. In countries with e-invoicing platforms (Italy, Romania, Germany from 2027), the original XML has already been transmitted — the platform holds a copy you cannot change

Beyond the legal mechanics, your client's finance team has likely already processed the original invoice. Sending a revised version with the same number creates duplicate-entry confusion in their accounting software and may result in payment delays or double-payment.

The correct approach is a credit note — a separate document that legally reverses the original invoice, in part or in full.

The 5 Situations That Require a Credit Note

1. Invoice error (wrong amount, wrong VAT rate, typo)

You issued an invoice for €5,000 but the agreed amount was €4,500. Issue a credit note for −€5,000 (full credit of the original invoice) and a new invoice for €4,500 with a new sequential number.

Alternatively, if the error is a small adjustment, issue a partial credit note for −€500, bringing the net amount to €4,500 without cancelling the original entirely.

2. Goods returned or service cancelled after invoicing

You delivered a service, invoiced for it, then the client legitimately cancelled under the contract terms. Issue a credit note for the full or partial amount agreed as a refund.

3. Service cancelled before delivery but after invoicing

You sent an invoice for upcoming work, then the project was cancelled. Issue a full credit note against that invoice. If you are entitled to a kill fee, issue a credit note for the full original amount and a new invoice for the kill fee amount only.

4. Agreed discount applied retroactively

You agreed to a 10% early payment discount but the client paid the full amount. Or a volume discount was agreed after invoicing. Issue a partial credit note for the discount amount.

5. Bad debt relief (client never pays)

You have exhausted payment collection and the debt is irrecoverable. A credit note for VAT purposes allows you to reverse the output VAT you already paid to your tax authority on income you never received. The mechanism and requirements differ by country — see the FAQ below for details.

Credit Note Mandatory Fields

A credit note must contain all the same mandatory fields as a standard invoice, plus two additional elements:

Example reference wording: "Credit Note CN-2026-007 — Issued against Invoice INV-2026-042 dated 15 February 2026. Reason: Partial cancellation of services by mutual agreement — amount credited: €1,200.00."

The amounts on a credit note are typically shown as negative figures: Net −€1,200.00, VAT −€228.00 (at 19%), Total −€1,428.00. Some accountants prefer to show positive figures with a clear "Credit Note" header; either approach is acceptable provided the document unambiguously reduces the amount owed.

Full Credit Note vs. Partial Credit Note

Full credit note: Cancels the entire original invoice. Use when the invoiced amount is completely wrong, the service was cancelled in full, or the invoice was issued to the wrong entity. After issuing, you typically follow up with a corrected invoice (new number, correct details).

Partial credit note: Reduces the original invoice by a specific amount. Use for discounts, minor overcharges, or partial cancellations where part of the service was delivered as invoiced. The original invoice remains partially valid; the credit note adjusts the outstanding balance.

VAT Timing Rules by Country

When you issue the credit note matters for your VAT return:

In practice: issue the credit note as soon as the decision to cancel or correct is made. Do not hold it to a specific calendar date unless your tax advisor recommends it for a specific reason.

Bad Debt Relief: Reclaiming VAT on Unpaid Invoices

If you issued an invoice with VAT, paid that VAT to your tax authority in your quarterly return, and then the client never pays — you have effectively donated the VAT to the government on income you never received.

Bad debt relief allows you to reverse this:

Germany (§17 UStG): The debt must be genuinely irrecoverable. Triggers include: client insolvency (Insolvenzverfahren opened), court judgment for the debt, or a documented history of failed collection. You adjust your output VAT in the period when irrecoverability is established — not simply because the invoice is overdue.

France (Article 272 du CGI): Issue a credit note to the client and obtain a certificat d'irrécouvrabilité (certificate of irrecoverability). The client must return the original VAT reclaim they made.

Netherlands (Article 29 Wet OB 1968): Submit a teruggaaf (VAT refund) request to the Belastingdienst when the debt is more than 1 year overdue or when irrecoverability is certain.

Important: bad debt relief typically requires that you have already issued a credit note or made a formal VAT adjustment entry. Simply writing off the debt in your accounts without the VAT adjustment does not reclaim the tax. Document everything — the original invoice, collection efforts (emails, legal letters), and the reason irrecoverability was established.

The Bookkeeping Entry for a Credit Note

When you issue a credit note, your accounting system should record:

1. Reverse the revenue entry from the original invoice (debit revenue, credit accounts receivable)
2. Reverse the VAT output liability entry (debit VAT payable, credit accounts receivable)
3. Net effect: accounts receivable balance reduces by the credit note gross amount

If you are using a cloud accounting tool (Lexware, Sevdesk, Xero, QuickBooks), creating a credit note linked to the original invoice typically generates these entries automatically. Check that the credit note appears in both the accounts receivable ledger and the VAT report for the correct period.
