Who needs ecommerce VAT and tax support in Spain?

​

• Non-residents running online businesses in Spain

​

What is OSS (One Stop Shop) and when does it apply in Spain?

​

OSS (One Stop Shop) is a system that simplifies VAT compliance for businesses selling goods or digital services across multiple EU countries.

Many ecommerce businesses in Spain are required to use OSS when selling to customers in other EU countries.

Instead of registering and filing VAT in each country where sales take place, OSS allows you to declare all those transactions in a single VAT return in Spain.

This significantly reduces administrative work, but it must be set up and managed correctly to avoid errors or penalties.

​

Common VAT mistakes ecommerce businesses make in Spain

​

Many online businesses unknowingly create tax risks when selling internationally.

Some of the most common issues include:

Applying incorrect VAT rates
Not registering for OSS when required
Issuing non-compliant invoices
Missing reporting obligations in multiple countries
Mixing personal and business activity

These issues can lead to penalties or unexpected tax liabilities if not handled properly.

 

How we help ecommerce businesses manage VAT and accounting in Spain

​

We start with an initial assessment to understand how your ecommerce business operates — especially if you sell across multiple countries in the EU.

Most of our clients are expats who are not familiar with the Spanish tax system, so our goal is not only to manage compliance, but also to explain clearly what your obligations are and how everything works.

During the first month, we focus on setting up your systems correctly.

We configure your ecommerce platforms — such as Shopify, Amazon or WooCommerce — and integrate them with our accounting system, Holded, one of the most modern tools available in Spain.

This allows:

Real-time accounting
Automated bank reconciliation
Income tracking by sales channel
Clear financial visibility

We also guide you on how to use the system so you can upload invoices, track expenses and understand your financial situation at any time.

Once everything is properly set up, your accounting becomes partially automated while we handle ongoing maintenance, adjustments and compliance.

On a quarterly basis, we prepare and submit your VAT and tax returns — which are typically more complex for ecommerce businesses than for other activities.

We also offer regular calls to review your tax filings and discuss your business.
