update

Changelog

We keep improving ladnepodatki.pl,
so that calculating taxes is simpler and more accurate.

Fix for VAT-free costs in the B2B calculator

24.08.2026
  • We fixed how costs are calculated for non-VAT payers — with “VAT on costs” set to 0%, costs were not reducing income tax or the health contribution.
  • Costs in this configuration now correctly reduce both the taxable base and the health contribution base, so your net profit is higher.

2027 tax bracket simulation

21.08.2026
  • B2B, UoP and B2B vs UoP comparison calculators now let you simulate the government proposal from 19 Aug 2026 — the 2nd bracket raised from 120k to 130k PLN and a 24% rate for income between 130k and 150k PLN.
  • Turn on the “Check” toggle in the banner at the top of the form to see your net income before and after the proposed changes (progressive tax scale).
  • The simulation also covers joint filing with a spouse; by default, calculators use currently applicable tax brackets.
  • The 2027 simulation panel now includes spouse settlement in net amounts; the UoP calculator shows “Net salary” instead of “Net profit”.
  • We refined icons and spacing in summaries — including IKZE, joint filing and the PPK/PPE savings section in UoP (clearer on mobile).
  • Smaller, more compact percentage chips for PPK and PPE contributions in the UoP form.

Vacation calendar 2026

01.08.2026
  • New vacation planning tool — an interactive calendar with public holidays and weekends.
  • Mark vacation days, set your allowance and share your plan via link.
  • Calendar data is saved in your browser; the page is available in Polish, English, Ukrainian and Russian.

Language versions added

30.07.2026
  • The site is now available in English, Ukrainian and Russian.
  • Added a language switcher with flags in the page header.
  • Changing the language keeps you on the same calculator or page.

PPE in UoP calculator and refreshed design

27.07.2026
  • The UoP calculator now supports PPE — the employee pension program alongside PPK.
  • The annual summary includes a new Savings section with PPK and PPE contributions.
  • We refreshed the app design and typography — results are easier to read on mobile and desktop.
