The 5 differences between a fake invoice and a falsified invoice that you should know about

The differences between false invoices and falsified invoices are vital in the financial and tax spheres. One term implies the creation of a document that never existed, while the other refers to the alteration of a legitimate invoice. For many CFOs, understanding these nuances is both a legal requirement and a strategic necessity to protect their reputation and ensure the health of the company. So let's analyze what these two types of fraud are, how to detect them with tools and best practices, what penalties they carry, and how to eradicate them from your electronic invoicing.

By definition, what is the difference between a false invoice and a falsified invoice?

To understand the difference between a false invoice and a falsified invoice, you first need to have a thorough understanding of the meaning of each concept. 

• False invoice: an accounting document issued by a supplier or company that does not exist or has not carried out any actual transactions. For example, this occurs when a company is created solely for the purpose of invoicing or documenting a transaction that never existed.
• Falsified invoice: part of a legitimate document, but its content is modified. In this case, two examples are increasing the amounts invoiced to deduct more VAT or changing dates, items, or recipients.

Basically, the main difference is that a false invoice does not exist and is a completely fabricated document, while a falsified invoice is a real document that has been manipulated with erroneous information in order to deceive.

The 5 differences between a fake invoice and a falsified invoice

From the definition of each, it is clear that a false invoice and a falsified invoice are not the same thing. They are sometimes mistakenly used as synonyms, but they have different and severe legal and tax consequences, especially if you are financially responsible in a company. 

Specifically, these are their five main differences :

Difference	False	Falseada
1. Document	The invoice is fictitious, as there is no actual transaction.	The invoice is real, but it has been altered or tampered with.
2. Nature of the fraud	He invents an operation that never happened.	Alter an actual transaction to modify quantities, items, or dates.
3. Tax risk	Very high. It may constitute a tax offense directly.	High, but it can be considered a violation if it does not exceed certain thresholds.
4. Detection by the Tax Authorities	It is easily detected by cross-referencing data between companies and non-existent suppliers.	It is more difficult to detect and requires detailed, technical analysis.
5. Intention of the sender	Falsifying income, transactions, or justifying expenses that never existed.	Inflating expenses, changing dates, or improperly taking advantage of deductions.

Practical examples:

• False invoice: a "ghost" company invoices another company for consulting services that were never provided in order to deduct VAT or justify expenses.
• Falsified invoice: a real transport invoice is modified by increasing the amount from €2,000 to €3,000 in order to deduct more VAT than is due.

Cases in which false or falsified invoices are used

1. Pay less VAT: increase expenses to deduct non-existent VAT and, therefore, deceive the supplier.
2. Reducing income/taxes: issue invoices with amounts lower than the actual amount by adjusting costs and income.
3. Capitalizing on unemployment by playing with documentation: simulating registration/service with false invoices.
4. Insurance claims or accidents: falsified invoices to justify a higher value of the asset.
5. Internal embezzlement: a person generates inflated expenses with falsified invoices.

How does the tax authority detect false or falsified invoices?

Both fake and falsified invoices are illegal. But how does the tax authority detect them? The control exercised by the Spanish tax authority is becoming increasingly intelligent and effective. 

In fact, today, with digitization and automated systems, the tax authorities can:

• Cross-check data and suppliers. This allows you to compare VAT numbers of suppliers and customers or detect missing suppliers in other tax records.
• Review Forms 347 and 349. This allows you to verify important transactions (e.g., foreign trade or intra-Community trade).
• Analyze Intrastat and IOSS. In other words, it performs internal control of trade operations.
• It applies OCR technology and document analysis. This method also recognizes patterns of falsification: atypical margins, manipulation of series, etc.
• It works with Big Data and company correlation. This allows it to detect invoices that fit fraudulent patterns: groups of related companies, unusual volumes, etc.
• On-site checks. Request documentation: contracts, delivery notes, accounting receipts.

In addition, the Treasury's data analysis engine automatically "alerts" about invoices that do not comply with consistency standards.

Tips for detecting a fake or falsified invoice

More specifically, to identify false and falsified invoices, you can also look at the following aspects in each case, as the tax authorities do.

Fake invoices

• Unknown supplier or without an online presence.
• Activity that does not fit with your sector or purchase volume.
• Incomplete data: Incorrect tax identification number, questionable address, omission of mandatory billing information...
• Unusual amounts in relation to your usual purchases.
• Inconsistencies in bank records: invoice issued but no transfer.

Falsified invoices

• Modified amounts with respect to accepted budgets or prior agreements.
• Altered concepts to justify VAT deductions or non-genuine expenses.
• Date discrepancy.
• Duplication or incorrect use of the same invoice in different accounting sections.
• Visible edits to a PDF: for example, the modified Adobe property.

Quick checklist for your financial team

We also provide you with a quick checklist so that you and your team can identify false or falsified invoices before they reach the tax authorities.

• Verify that the supplier's tax identification number appears in the tax registry.
• Cross-check supplier and bank: does it add up?
• Compare a history of regular expenses.
• Check dates: issuance vs. service vs. collection...
• Use accounting software with legal formats and that detects alterations (PDF+XML versioning).

Penalties applicable for falsified and false invoices

If the tax authorities identify any of these documents, there is a risk of penalties such as those mentioned below. 

• Minor tax violation: 50% penalty on the amount owed, if corrected.
• Serious violation: this is where falsified invoices are categorized, at most. They are 100% of the tax base and 150% if there is repeated false documentation.
• Tax crime: false invoicing usually carries a fine proportional to the amount defrauded (up to 150%) and prison sentences of 1 to 6 years in serious cases (Article 305 of the Criminal Code).

Invoice type	Tax violation	Potential penalties/practices
Totally false	Tax offense if serious; Minor/serious violation	Imprisonment (1–6 years) + fine + AGILE block
Falseada	Minor or serious violation	Fine of 100-150% and deduction rejected

In addition, there are more indirect risks such as:

• Loss of right to deduct of VAT.
• Reputational repercussions on the media and customers.
• Control and preventive blocking by the Treasury, which will halt subsequent declarations.
