Traceable VAT correction: what information is required under the European directive

01

What makes a VAT correction traceable

Traceability depends on the ability to verifiably link the corrected invoice to the original transaction. The directive requires that the authenticity of origin, integrity of content and legibility of the invoice be guaranteed from issuance until the end of the archiving period, including through business controls that create a reliable audit trail between the invoice and the supply of goods or services. The amount of VAT payable or to be adjusted must be expressed in the national currency. Sufficiently detailed accounting allows the tax administration to verify the application of the tax.

02

The regulatory framework of reference

The reference is Directive 2006/112/EC on the common system of VAT, which governs declarations, invoicing and archiving across all Member States. The VAT return must contain all the data needed to determine the tax due and the deductions to be made, including exempt transactions, within a deadline set by each Member State and referring to a tax period of one, two or three months, unless a different duration not exceeding one year is set. If invoices are stored electronically, the Member State may also require the data guaranteeing authenticity and integrity, and grant authorities the right of access.

Operational sequence for a verifiable correction

Steps

1. Check that the original invoice contains all the elements set out in Article 226, including the taxable amount per rate.
2. Link the correction to the transaction through business controls that form a reliable audit trail.
3. Record the VAT amount to be adjusted in the national currency, even if the original invoice was in another currency.
4. Revise the accounting records with sufficient detail to allow the tax administration to carry out checks.
5. Archive the copy of the corrected invoice together with the original one, ready for access by the authorities.

04

A hypothetical case

Hypothetical example: a company issues an invoice with an incorrect VAT rate and needs to correct it. To make it traceable, the new invoice shows the same transaction date, the quantity and nature of the goods supplied, the correct taxable amount for the applied rate, and a reference linking it to the original invoice through the company's business controls, so that the audit trail between the correction and the supply can be reconstructed.

05

Elements to check before recording the correction

• The corrected invoice states the date, quantity and nature of the goods or services.
• The taxable amount per rate and the VAT amount are expressed correctly.
• The accounting records link the correction to the original invoice with verifiable detail.
• Copies of both invoices are archived and accessible to the authorities.
• The correction data is reflected in the VAT return for the correct period.

06

How management software can support these requirements

Management software can be configured to support these requirements without replacing the company's own legal assessment. A responsible role can be assigned for each correction, the new invoice can be linked to the original one with a unique reference, and both versions can be kept with their issue and archiving dates. A review workflow can require verification of the Article 226 elements before recording, while a change log can show who created the correction and when, making the audit trail queryable in case the tax administration requests it. These are suggested operational choices, not requirements guaranteed by the software.

07

Frequently asked questions on traceability

• The audit trail required by Article 233 can be based on internal business controls, not only on technical tools.
• The archiving obligation covers both issued and received invoices, including corrections.
• The corrected VAT amount must always appear in the national currency of the Member State.

Before recording your next correction

Check that the new invoice contains the elements set out in Article 226, that it is linked to the original one by a reliable audit trail, and that both versions are archived in a way accessible to the authorities.
