Welcome to SimplyVAT.nl

Every organization and business is different. But all companies, large or small, locally or internationally active, profit or loss making: all should take into account VAT. VAT is a tax imposed on transactions. With every purchase and sale it must be determined whether and which VAT consequences this activity may have. Suppliers calculate VAT, and you want to reclaim this VAT. And with every supply of a service or a good you need to determine whether and how much tax should be calculated.

The management and mapping of processes in the field of indirect taxation (VAT, customs and excise duties), explaining and implementing and applying the rules, and finally filing a proper Return can sometimes be very complicated. The solution? Click on the options below and see where I can help you.

In-house VAT Training

VAT is included in all processes of a business. A standard VAT training is often one-sided and does not include the necessary topics and details that are important for all these processes.

A specific in-house VAT training ensures that the right people are trained at the right level, so that the whole organization eventually can deal with its VAT obligations much more efficiently.

VAT Interim Management

Even companies that have a dedicated in-house VAT specialist, practical VAT issues and questions may be difficult to cope with due to time-restraints, lack of knowledge or because of special projects.

A (temporary) expansion of your tax or finance department with a pragmatic, knowledgeable and experienced VAT specialist is the ideal solution for that.

Indirect Tax Advice

Companies are changing continuously. VAT rules as well. The difficulty is to translate the VAT rules into your business processes in a clear and simple way. 

With almost 20 years experience as indirect tax advisor and as 'in-house' indirect tax manager with global responsibility for indirect taxes in large multinational companies, I can assist you with all you VAT, customs and excise related questions, efficiently and effectively.
