I would like to present you my first app in Google Play. It is Income Tax Calculator for Poland.
By means of Income calculator you can count in a simple way net income/gross income/costs of employer for each form of employment in Poland:
- labour contract (Umowa o pracę)
- contract of mandate (Umowa na zlecenie)
- contract of specific work (Umowa o dzieło)
- self-employment (Samozatrudnienie)
You can download it from:
