SISTERdigi

SISTERdigi is a web system for submitting tax forms online, including the annual settlement of advance payments and tax relief. It began as a tool for that purpose and has since been extended with modules for other tax requests and for personnel and tax administration.

Customers are employers and their payroll accountants, HR staff and administrators, as well as employees, who see only the functions their role allows. The website lists per-user licences from 340 CZK per year and a system licence from 59,000 CZK per year, which includes one year of support and implementation of legislative changes.

The product is run by SISTERdigi, s.r.o., registered in Prague with a founding date of 25 February 2025; the registry lists it as a subsidiary of a foreign group. The website's Czech home page cites user and company counts, but the numbers are shown as placeholders and are not reproduced here.
