For tax reasons, if you make a mistake when issuing an invoice to a customer, you must issue a corrective invoice. In fact, the law forbids you to delete an invoice, it must be replaced by a new one.

The obligation to follow the numbering of the invoices is a way of being able to verify that none is missing. A "hole" in the numbering could mean that you have made an invoice disappear. In order to manage invoice errors, we would like to introduce you to a type of invoice adapted for this purpose: the rectifying invoices.

What is an amendment invoice?

A rectifying invoice is generated like a standard invoice. This type of invoice replaces an invoice with errors either in the total amount or in the data that must be included according to the regulations.

A rectification invoice must include all the mandatory information in the same way as an original invoice. However, both the credit invoice and the amendment invoice must refer to the original invoice(invoice number and date).

How to make a corrective invoice

The corrective invoice is usually identical to the original invoice with the modifications resulting from the corrections. Then, from the original invoice we must make the following modifications:

Specify the reason for the change with respect to the original invoice.
Use a different numbering (usually starting with an R: R00345, R00346, etc.).
Place the reference of the original invoice.
Make the corresponding change: VAT, customer data, total amount, etc.

The invoice is an official document and a legal obligation, therefore, respecting the regulations is of utmost importance. The most efficient way to make invoices is to automate the calculations and the integrity of the process.

Credit Correction Invoice

The credit invoice is a type of amendment invoice. The amendment invoice is relatively new (2013), previously the credit invoice was the document used to correct/replace an invoice. Nowadays, credit invoice and amendment invoice are synonymous.

However, there are positive credit amendment invoices and negative credit amendment invoices.

Positive credit amendment invoice

The crediting of this invoice is positive for the company, i.e. the company has made a mistake in favor of the customer. The company will receive more money than the initial amount.

Negative Credit Correction Invoice

The credit of this invoice is negative, i.e. the company has made a mistake against the customer. The company must pay the differential to the customer.

Requirements and mandatory data in the amendment invoices

In addition to the reference to the original corrected invoice, all corrective invoices must state that they are corrective invoices, as well as the description of the reason for the modification.

Likewise, the following must appear, as the case may be:

names and addresses of the parties,
amount excluding the discount and the corresponding VAT ,
amount of the total VAT and the VAT due after the application of the discount,
Identification and proper numbering.

Numbering of rectifying invoices

Although it follows the same invoicing scheme, the rectifying invoice must be differentiated from the ordinary invoice. Therefore, the amendment invoice must have a header describing the type of document. In this sense, the amendment invoice must have a different numbering from the original one.

The numbering must be correlative and the invoices must be identified as rectifications, as mentioned above this is done through the R or RT nomenclature and be ordered by ascending date.

The objective is to differentiate in order to facilitate the identification and accounting of the same.

What is the deadline for issuing the rectifying invoice?

The rectification can be made within the following four years from the time the tax was accrued or from the date on which the circumstances regulated in Article 80 of Law 37/1992, which give rise to the modification of the VAT taxable base, have occurred.
