ITAX – TAX-Tools

As tax systems become ever more complex and reporting obligations increase, IT solutions are gaining importance. They enable companies to retrieve information about their tax burden quickly and easily, to identify potential areas for optimisation and, last but not least, to be sure that they fulfil their tax reporting obligations.This applies to VAT and income tax transactions in particular, which are often handled in bulk, but in which even small errors can have serious consequences for a company.
An IT-based tax solution will achieve the most and be the most efficient if it is adapted to the company’s individual situation. That is why we at WTS place high value on tailored implementation. Our experts develop the right IT-based tax solutions for your specific issues and business processes, and integrate these into your existing IT infrastructure. We see tax consultancy and IT implementation as one entity, which is why consultants across all disciplines of the WTS group are trained using a strictly integrated consultancy approach.
