How it works
Upload a supported PDF or photo. The output separates meaning, dates and suggested actions so you can compare each point with the original document.
Illustrative output
Document type
Example · monthly payslip
What this says
You earned €4,850 gross this month. After tax and deductions, the example shows €3,210 net. The figures shown do not point to an obvious issue.
Worth checking
The tax-free allowance of €1,455 is close to 30% of gross. That is consistent with the example, but the calculation basis still needs to be checked on the payslip.
Next step
No immediate action is suggested in this example. Keep the payslip with your records.
Check any result against the original document and the relevant official source. DutchDecoded provides information, not legal, tax or immigration advice.
Deadline guardian
Guardian uses the details you provide to show supported deadlines that may be relevant. Each entry keeps the rule, consequence and official source together.
4 months from employment start
Applying within the window can affect the date from which an eligible decision takes effect.
Usually within 5 days of arrival
For people staying longer than four months, municipal registration creates the BRP record and BSN.
As soon as possible; commonly within 4 months
The applicable timing depends on whether Dutch basic insurance is compulsory in your situation.

How the product earns trust
Dutch terms are explained in the context of the document. Results should still be checked against the original.
Tracked deadline rules include their relevant official source, so the basis is available for inspection.
Raw files and explanations are not saved in the DutchDecoded database. Files pass through Vercel to Anthropic for analysis; Anthropic API retention of up to 30 days applies.
