Legal advice for all stages of a tax dispute

Understanding what tax avoidance is, what is the "right tax" - and what is not – is essential for any business. New laws have led to greater scrutiny of whether businesses are paying the right taxes in the right jurisdictions.

Tax authorities often now pursue businesses for tax that would not have been pursued a few years ago. In some cases, domestic governments have granted tax authorities significant new powers to demand information and collect tax even before it is shown to be due. They may also require corporations to police other taxpayers.
