VAT Reporting During the Tax Filing Period: What E-Commerce Businesses Should Check

Introduction

For e-commerce businesses operating in the European Union, VAT is one of the most complex and sensitive areas of compliance. During the tax filing period in the Netherlands, VAT reporting becomes a critical checkpoint—not only to confirm accuracy but also to identify inconsistencies across systems, transactions, and jurisdictions.

Unlike corporate income tax, VAT is reported periodically throughout the year. However, the tax filing period is often the moment when discrepancies become visible, particularly for businesses with cross-border operations, multiple sales channels, or high transaction volumes.

At TAMM Solutions, we support e-commerce companies by ensuring that their VAT, administrative, and operational setupis aligned and compliant—especially during this key reporting period.

Why VAT Requires Special Attention During the Filing Period

VAT errors are among the most common triggers for audits and corrections. During the tax filing period, businesses should:

• Reconcile VAT returns with accounting records

• Verify cross-border transaction treatment

• Confirm alignment with customs and logistics data

• Identify reporting inconsistencies

For e-commerce businesses, these checks are essential due to the complexity of their operations.

Key Areas E-Commerce Businesses Should Review

1. Alignment Between Sales Data and VAT Returns

E-commerce businesses often operate across multiple platforms:

• Webshops

• Marketplaces (e.g. Amazon, Bol.com)

• Payment providers

It is essential to ensure that:

• Reported revenue matches VAT filings

• Marketplace sales are correctly reflected

• Refunds and returns are properly accounted for

Misalignment here is one of the most frequent sources of VAT discrepancies.

2. Cross-Border VAT Treatment

Selling across the EU introduces additional complexity. Businesses should review:

• Intra-EU supplies and distance sales

• Correct application of VAT rates

• OSS (One-Stop Shop) reporting where applicable

Incorrect classification of cross-border sales can lead to underpayment or overpayment of VAT.

3. Import VAT and Customs Data

For businesses importing goods into the EU:

• Import VAT must align with VAT returns

• Customs declarations should match accounting records

• Article 23 deferral (if used) must be correctly applied

Discrepancies between customs and VAT data are a key audit trigger.

4. Warehouse and Fulfillment Structures

Using multiple warehouses or fulfillment providers can create complexity. Businesses should verify:

• Where goods are stored

• Which country VAT applies

• Whether additional VAT registrations are required

This is especially relevant for businesses using EU-wide fulfillment networks.

5. VAT Registration and Reporting Scope

Businesses should confirm:

• All required VAT registrations are in place

• Reporting obligations are correctly fulfilled

• No jurisdictions have been overlooked

Late or missing registrations are a common issue for growing e-commerce companies.

Common VAT Mistakes in E-Commerce

In practice, we frequently see:

• Incorrect treatment of marketplace sales

• Missing VAT registrations in certain EU countries

• Misalignment between logistics and VAT reporting

• Inconsistent handling of returns and refunds

• Errors in OSS reporting

These issues often arise due to rapid growth and system complexity.

The Role of the Dutch Tax Authorities

VAT compliance is closely monitored by the Dutch Tax and Customs Administration, particularly for:

• Cross-border e-commerce

• Import structures

• High-volume transactions

Authorities increasingly rely on data matching between:

• VAT filings

• Customs declarations

• Third-party platform data

How to Approach VAT Reporting Strategically

A structured approach includes:

• Regular reconciliation between systems

• Clear documentation of VAT treatment

• Alignment between logistics, accounting, and VAT

• Coordination between internal teams and advisors

VAT should be treated as an operational process, not just a reporting obligation.
