How can Baat be of service to you?


Given the fact that national borders  are always near in Limburg over the course of years we have developed an accountancy and consulting practice with a strongly  internationally orientated character. We service our clients  from offices in Maastricht, Roermond, Sittard and Maasmechelen (Belgium).


Next to the regular accountancy  and consulting practice, Baat is spezialized in tax and social security issues related to cross-border labour. The specialists from our cross-border labour team are happy to assist you, whether you're an employee or an employer.


Our services in short:

  • The preparation of income tax returns | check of income tax assessments
  • Advice on social security | application of A1 certificates
  • Advice on 30% ruling | split payroll issues
  • Payroll

We  make pro forma payroll calculations, examine the options to optimize salary splits and secondment situations and offer insight in which country an employee has to pay taxes and social premiums.


Over the course of the years, Baat has built up an extensive international network. We'll be happy to let you benefit from that expertise pool!


We'll be happy to communicate with you in English, French and German, both spoken and in writing.
