Top 10 VAT Audit Questions Answered

VAT audits can be really stressful, so it’s no wonder we get so many questions about them. Knowledge is power, so we’ve answered the most common VAT audit procedure questions in one place for your reference. 

VAT Audit Questions and Answers 

What triggers a VAT audit for an ecommerce business selling in multiple countries? 

Getting audited doesn’t necessarily mean you’ve done something wrong. You could have to face a VAT audit for several reasons: 

  • If you miss a VAT filing
  • Your sales or import data is mismatched
  • Your VAT refunds are unusually high or low
  • You’ve been randomly selected 

Selling across borders increases the likelihood you’ll be audited, as you’ll be working with more tax authorities. 

How long do I need to keep my VAT and transaction records in case I’m audited? 

How long you need to keep your records varies by country, but generally speaking, it’s between 5 and 10 years. If you do business in multiple countries, you’ll need to keep everything for the longest required period. For example, if one country requires records for 10 years and another for 6, keep everything for 10. This is so that you have the complete picture for a period, should you be audited. 

Can a past VAT mistake be corrected during an Audit without me getting a penalty? 

Penalties really depend on the situation and your behaviour. By that we mean: 

  • How big the error is
  • How old the error is
  • Whether you’ve voluntarily disclosed it
  • Whether it’s a genuine mistake or deliberate VAT fraud 

The Tax Authority doing the audit also makes a difference to the level of penalty you get. Every country has different laws that set out levels of penalty and the situations in which they apply. 

What’s the difference between a desk audit and a field audit for VAT? 

A desk audit is done remotely. The Tax Authority will review the returns you’ve submitted and the electronic versions of supporting documents. A field audit involves physical documents, and sometimes an auditor will visit your business in person. This is usually reserved for cases where serious fraud is suspected. 

For ecommerce sellers shipping internationally, desk audits are far more common.

What documents should I have to be ready for a VAT audit? 

Some countries require specific documents, but generally, ecommerce businesses should have: 

  • Invoices for sales and purchases
  • Shipping and customs documents
  • Customer address records
  • IOSS/OSS declarations
  • VAT returns
  • Bank Statements
  • Any correspondence with the tax authorities 

You should store these documents by date and by country. Even if you have a period with no sales, hold onto any relevant documents from that time. 

Can I get a VAT consultant to handle a VAT audit for me? 

Yes, and in fact, this is something that SimplyVAT can help you with. We can talk to the Tax Authorities on your behalf and handle all the paperwork for you. Audits can be stressful, especially if you don’t speak the same language as the Tax Authority. Working with a team like ours gets you process expertise in over 10 languages. 

What common mistakes do ecommerce businesses make that get them audited? 

The most common mistakes we see that have triggered an audit are: 

  • Sales and returns data that doesn’t match
  • Under-declared imports or sales
  • Missing or late VAT, IOSS or OSS returns
  • Inconsistent or incomplete invoicing
  • Messy record keeping

Incorrect invoicing is a really common problem and causes all sorts of issues – not just getting audited. 

It’s important to remember that a good portion of audits are routine, and not because you’ve done something wrong. You might be chosen at random or because a Tax Authority has a policy of conducting an audit when you take a specific action. For example, requesting a refund in Poland might trigger an audit. 

I’m registered for VAT in multiple countries. How can I easily stay ready for an audit? 

The easiest way to store your records is by country and date. Use a consistent naming convention for all your files and timestamp them. Building a master spreadsheet isn’t a bad idea, but even better would be finding accounting software that can help you keep everything in order. 

Can a VAT audit result in me getting a VAT refund? 

Yes! If an audit uncovers that you’ve overpaid VAT, you might end up with credit or be in a position to claim a refund

How far back can a Tax Authority audit? 

Many EU countries allow audits to review up to the last 10 years. However, it depends on the local statute of limitations. When you’re selling internationally, you’ll be dealing with multiple jurisdictions. You should keep your records for the longest period in any of the countries you’re operating in. 

Even if you stop trading in a country and de-register, you should keep your records for the required period. The Tax Authority can audit you within the period of the statute of limitations, even if you’re not VAT-registered in their jurisdiction anymore.
