Notes about the TAXX file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.

Ringler Informatik is a Switzerland based global eTax and eForms solution provider for government institutions, tax professionals and tax payers.
