Your challenges in the field of VAT: Is this familiar to you?
International VAT compliance is a maze of rules, thresholds, and deadlines. You’ve probably faced:
- Constantly changing legislation: VAT rules in the EU and other countries are regularly updated, and it is extremely difficult to keep track of everything.
- The risk of unintentional errors: An incorrect rate, an incorrectly executed document, or a missed deadline can have serious consequences.
- Huge time costs: Registration, data collection, preparation, and filing of declarations take away valuable time that could be spent on business development.
- Fear of checks: Uncertainty in the correctness of accounting creates constant tension.
- Difficulties with OSS and IOSS: New systems for e-commerce simplify but require a precise understanding of the principles of operation.

FAQs about VAT Compliance
What is VAT Compliance in simple words?
This is the process of complying with all the rules and requirements related to value-added tax (VAT) in the countries where your business has tax obligations.
When does my business need VAT registration in another country?
The need arises when certain thresholds are reached in sales volume to that country, when there is a warehouse in the territory of that country, when certain services are provided, or in other cases provided for by local legislation. We will help you determine when and where you need registration.
How does OSS differ from regular VAT registration?
One Stop Shop (OSS) is a simplified system that allows you to register for VAT in one EU country and report on sales of goods and services to end consumers in all other EU countries through a single declaration. This greatly simplifies the process for e-commerce but does not completely replace regular registration if you have a warehouse or other obligations in a specific country.
What happens if you do not comply with VAT Compliance?
Failure to comply with VAT obligations can lead to severe consequences, including significant fines and penalties, backdated VAT assessments, potential blocking of bank accounts, prohibition of business activities in a country, damage to your business reputation, and complications for future operations in that jurisdiction.
How long does VAT registration take?
The timing depends on the specific country and the workload of its tax authorities. We will do everything possible to expedite the process and will keep you informed at every step.
What information will you need from me to start?
Initially, we will need information about your company, business model, sales volumes, and the geography of your operations. A complete list of documents and data will be provided after a consultation and assessment of your specific situation.
How much do your VAT Compliance services cost?
The cost depends on the volume and complexity of your operations, the number of countries requiring registration, and the frequency of declarations filed. We offer individual service packages. Contact us for an accurate quote after analyzing your situation.
