According to the European Commission, 7.6% of the value-added tax (VAT) that should have been collected in Spain in 2023 was not. This is partly due to administrative and calculation errors. To reduce these incidents, The Create and Grow (Crea y Crece) Law passed that same year. The law introduced several changes and mandatory electronic invoicing requirements.

Electronic invoicing reduces manual intervention. Therefore, it also reduces errors on invoices. However, it does not completely eliminate inaccuracies when issuing invoices. It also does not eliminate the need to make subsequent modifications to invoices to apply discounts or document returns. Regardless of the reason for changing an original invoice, Spanish regulations provide a legal mechanism to do so: the corrective invoice. In this article, we explain corrective invoices, including when and how to issue them.

What is a corrective invoice?

A corrective invoice changes a previous invoice and records the corrections applied. It must be issued when the changes affect the tax base, tax amount, or identifying information on a previously issued invoice. In Spain, there are three types of corrective invoices, including those for differences, replacement, and credit.

• Corrective invoices for differences: These corrective invoices complement the original invoices and serve to correct specific errors.
  
• Corrective invoices for replacements: In this case, the corrective invoice cancels the previous invoice and legally replaces it. It is issued to correct various types of errors in the mandatory information on the original invoice, such as an incorrect Tax Identification Number (NIF) in a B2B transaction.
  
• Corrective invoices for credits: This subtype of corrective invoice is known as a “credit note” and shows a decrease in the tax base due to returns or discounts. It is issued to return an amount or to compensate for a charge that was higher than what was due.
  

Differences between corrective invoices and credit notes

Corrective invoices are established by regulations to correct errors in previously issued invoices. Credit notes are a subcategory of corrective invoices. Therefore, they share some characteristics. For example, both are used to change previous invoices, and both must contain virtually the same information. However, there are certain differences, depending on the type of invoice. Here are the main differences:

• Identification of the previous invoice
  On a corrective invoice, it is mandatory to identify the original invoice. Conversely, on a credit note issued to change the tax base when applying a purchase volume discount, it is not necessary to identify the previous invoice. Instead, it is sufficient to specify the period, as established in Article 15.4 of Royal Decree 1619/2012.
  
• Type of change
  Corrective invoices allow for upward and downward changes and other corrections, such as the invoice number, date, or customer name. On the other hand, credit notes only allow for downward changes to the amount (i.e., reductions).
  
• Positive or negative amount
  The amount of a corrective invoice can be positive or negative, depending on the correction applied. However, on a credit note, the amount is always negative because it exclusively reflects a balance in favor of the customer.
  

When is it mandatory to issue a corrective invoice in Spain?

Article 15 of Royal Decree 1619/2012 specifies cases when corrective invoices must be issued in Spain. Here is a summary of the three cases:

• Content errors
  It is mandatory to issue a corrective invoice when the invoice contains content errors, such as the number or series, date, identifying information, or description of the transactions.
  
• Tax base errors
  When the actual value of the transaction does not match the value shown on the original invoice, a corrective invoice is mandatory. If the original tax base is reduced (e.g., by applying a discount or receiving a purchase refund), the issued invoice is considered a credit note.
  
• Tax amount errors
  This occurs when the tax base is correct, but the tax amount has an error. This is common when manually calculating the VAT percentage or when mistakenly believing that a transaction is a non-VAT transaction.
  

For credit notes issued in bankruptcy proceedings, deadlines are set by the Bankruptcy Law. However, corrective invoices must be issued as soon as a company becomes aware of the situation. This must be within four years since one of the following situations:

• Accrual of VAT on the invoice (i.e., the moment when the obligation to declare it arose)
  
• Change in the VAT tax base for any of the reasons set forth in Article 80 of the VAT Law
  

Failure to issue a corrective invoice for these mandatory scenarios within the established deadlines can result in penalties. This can include fines from 50%–100% of the amount of incorrectly declared VAT.

Example of a corrective invoice in Spain

Corrective invoices vary depending on the information from the original invoice that needs to be corrected. To better understand this step-by-step process, we include an example below that features two of the most common modifications made by Spanish companies: identifying information and tax base.

Suppose a company in Seville sells a product to a business in Barcelona for €30 excluding VAT, but its actual value was €300. After issuing the initial invoice, the issuer realizes that error and notices that the customer’s tax address is also incorrect.

The table below demonstrates how to apply these changes to the new document to ensure compliance with the Spanish Tax Agency’s invoicing regulations:

How to create a corrective invoice with Stripe

If you use Stripe Payments to process payments for your business, you can offer more than 100 payment methods to customers in 195 countries. This payment gateway simplifies the purchase process and allows you to apply promotions, such as discounts on specific products or coupons. Regardless of the type of promotion, Stripe carries out the process automatically, which helps to minimize errors that require issuing corrective invoices.

Furthermore, to facilitate the creation of corrective invoices and many other operations, Stripe has the Stripe App Marketplace. This is a library of applications that easily integrate with your payment platform and adapt to the most specific needs of your business.

One of the applications available in the App Marketplace is Billit, a pioneering electronic invoicing platform in Europe that focuses on ensuring compliance with various electronic invoicing requirements across the EU. Billit has automated features that allow you to link your company’s bank account and simplify invoice reconciliation.

On the other hand, Invopop is a solution developed in Spain that has specific functions for editing corrective invoices and other commercial documents to ensure compliance with Spanish regulations. One of its most important features is its complete integration with the Verifiable Invoice Issuance System (VERI*FACTU) to send invoices in real time to the Tax Agency. This is expected to be mandatory starting January 1, 2027. Furthermore, Invopop complies with certain regional regulations, such as TicketBAI in the Basque Country. In fact, it is listed as certified software for TicketBAI by the Provincial Tax Authorities of Álava, Vizcaya, and Guipúzcoa.

FAQs about corrective invoices in Spain

Can a business issue a corrective invoice to increase the tax base?

The tax base can only be increased using a corrective invoice for B2B transactions. For example, this is the case if a company makes a calculation error and applies a price without VAT or a lower tax amount, and the company realizes it after issuing the invoice. Conversely, if the customer is a private individual (i.e., a B2C transaction) and the reason for the price increase is not covered by Article 80 of the VAT Law, the company cannot issue a corrective invoice to increase the VAT amount charged.

There is one exception: in the case of an increase in VAT rates, a corrective invoice reflecting the increase can only be issued before the end of the month following the month the increase took effect.

Can a business issue a corrective invoice if the original does not include VAT?

Yes, according to regulations, businesses can issue corrective invoices if the original invoices do not have VAT charged in the following two cases:

• VAT-exempt transactions: A corrective invoice can be issued if the original invoice should not include VAT (e.g., in the case of an intracommunity transaction) but contains errors in other information, such as the customer identification, item, etc.
  
• VAT omission errors: This happens when the original invoice should have included VAT, but it was not included or added to the tax base.
  

How is a corrective invoice recorded?

Recording a corrective invoice in Spain depends on its subcategory, including corrective invoices for replacement, differences, or credit. If it is a corrective invoice for replacement, it cancels the original invoice. Therefore, the correct final amount shown on the corrected and final invoice must be recorded. For corrective invoices for differences or credit, only record the amount of the difference.
