Een praktisch planningsplatform voor Europese werk-, salaris- en btw-vragen

WorkDaten begon begin 2025 als een persoonlijk spreadsheet. Ik werkte als freelance softwareontwikkelaar gevestigd in Oostenrijk, werkte voor klanten in Duitsland, Nederland, Frankrijk en Italië, en bleef dezelfde antwoorden nodig hebben: hoeveel werkdagen heeft dit kwartaal in welk land, wanneer is de volgende feestdag daar, wat is de huidige Blue Card salarisdrempel dit jaar, en hoe factureer ik precies een Duitse B2B-klant vanuit Oostenrijk met btw-verlegging?

Telkens als ik een van deze antwoorden zocht, sprong ik tussen vier overheidssites in drie talen, een paar expatforums van twijfelachtige actualiteit en enkele blogs van boekhouders die elkaar tegenspraken. Ik besteedde meer uren aan datacheck dan aan klantcode. Na drie maanden begon ik één persoonlijk document bij te houden, één tabblad per land, met de data en de bron-URL's.

Halverwege 2025 was het spreadsheet nuttig genoeg om als kleine website voor mijn eigen bladwijzers te herbouwen. Vrienden en andere freelancers vroegen toegang. Eind 2025 was duidelijk dat de site iedereen kon helpen die werkende leven over Europese grenzen plant — payroll-teams bij kwartaalafsluiting, HR bij verlofplanning, freelancers met grensoverschrijdende facturen, families die overwegen te verhuizen. Dus heb ik het netjes herbouwd, in vijfentwintig talen, en online gezet.

Every piece of substantive information on WorkDaten is traced back to a primary source — a government website, an EU regulation, a published statistical release, or a parliamentary gazette. Aggregator sites, commercial blogs and AI summaries are not acceptable sources for us. When we cite a salary threshold or a visa requirement, we link to the exact decree that set it.

Translations into our twenty-five languages are produced by professional translators and human-reviewed before publication. We do not publish raw machine-translated text as final content; pages we have not yet been able to translate to that standard are held back from indexing rather than served as low-quality content. The same rule applies to substantive text: WorkDaten does not publish AI-generated articles.

Each visa, holiday calendar and salary page is reviewed end-to-end at least once per year, and again whenever a legislative change comes to our attention through official-gazette monitoring. The "Reviewed by the WorkDaten editorial team on …" date you see at the top of every content page is the date of the most recent review, not the date the data was first published.

WorkDaten is self-funded by its founder, runs on a small Vercel hosting bill, and accepts no outside investment. We do not represent any law firm, relocation agency, immigration consultancy, bank or accountant. We do not accept payment for editorial coverage and we do not amplify or hide a country, visa or city based on commercial interest.

If at some point we add affiliate links — for example to a recognised bank that offers expat-friendly accounts, or to a credentials-evaluation service — those links will carry a visible "Affiliate" tag and will appear only where the recommendation is genuinely useful to the reader, never on the data pages themselves. Until that day, every link on this site is editorial.

The next twelve months are about depth, not breadth. Immigration coverage will expand from the current six countries (Germany, Austria, Spain, Italy, the Netherlands, France) to also include Portugal, Ireland, Belgium and Sweden, each with the same Austria-level depth — full visa pages with eligibility, salary thresholds, document checklists, family rules and PR pathways.

Working-days and public-holidays pages will gain seasonal context and bridge-day analysis for every month. The salary section will gain per-country take-home pay calculators that read directly from the tax-bracket data. We will add a visa-fee calculator and an EU residence-permit eligibility quiz before the end of the year.

If you spot a mistake, a stale figure or a missing visa, the Contact page reaches us directly. Reader corrections move faster than any of our internal review cycles, and we are grateful for every one.
