Taxonary helps all kind of companies, staffing agencies, and employees calculate salaries, taxes, allowances, and project costs for posted workers and cross-border work in the EU.

A posted worker is someone who temporarily works in another country while staying employed by their home-country company.


Calculating salaries and costs for posted workers in the EU is complex and time-consuming. Different tax rules, allowances, and hidden costs can lead to mistakes, delays, and fines.
Taxonary makes this easy by giving fast, accurate, and contract-ready calculations based on real data. It adjusts to each case - so you can get clear answers for any project, client, or country. This helps you explain your pricing, make quicker decisions, and reduce financial risks.
Getting tax calculations wrong in EU isn't just a minor error — it can lead to audits, fines, back payments, and even bans from future contracts.
Local tax authorities in countries like Norway, Sweden, and Denmark are strict, and non-compliance is treated seriously. A single mistake in calculating employer or employee obligations can put your project, reputation, and finances at risk. When every detail matters, guesswork isn't an option.

Taxonary helps businesses manage posted worker taxation and compliance across the EU.
