Expat Income Tax Advice

Per definition a cross border tax situation is complex, as the employee is usually confronted with at least two jurisdictions. Where you I pay taxes? How do I do that? What is the impact on my personal deductions and investment? Can I get the 30% ruling? Where should wage taxes be withheld? What about my social security position?

The TTT team combines over 40 years of Big Four experience with these type of questions and will help you understand, comply and plan with Dutch and international tax rules.

National Wage Tax Advice

Did you know that wage tax (or payroll tax) is the highest contributing tax on the Dutch government budget? Employers act as tax collector for the government. And have to follow strict, detailed and complex rules in order to calculate the amounts to be withheld and paid. Optimising your compensation and benefits plans can help you lower your cost base, increase the reward of your employees and limit the risks of you as a company.

Do you want to know where your organisations has opportunities? One of our experienced consultants is pleased to visit you.

Tax Control Framework

A Tax Control Framework helps you set tax goals, identify the risks that may jeopardise success, define controls to avoid or limit those risks and monitor the performance of your payroll tax function. The Dutch tax authorities demand a Tax Control Framework as a pre-requisite for agreeing on horizontal monitoring.
TTT has a broad experience with supporting companies in the development, testing and implementation of national and global payroll control frameworks.

Dispute resolution with the Dutch tax authorities (“inkeer”)
