Translating a Dutch letter from a photo: why a translation may not be enough
Published: October 9, 2026 · 4 min read · The Letrin team
Dutch words in this post
Hover over an underlined word in the text (tap it on a phone) and see what it means straight away.
| Word | Meaning |
|---|---|
| aanslag | tax assessment · In everyday language it means 'attack' |
| voorlopige aanslag | provisional tax assessment |
| beschikking | administrative decision |
| dagtekening | date of the letter · The date from which periods are counted |
| bezwaar | objection |
| betalingskenmerk | payment reference |
| BSN | citizen service number |
| IBAN | bank account number |
| bijlage | enclosure |
When a Dutch letter arrives, many people point their phone camera at it and use a translation app. That makes the text of the letter readable. A translation, however, conveys what the letter says; it does not tell you separately what you are expected to do, by which date, or what happens if you do nothing.
Translation and explanation
We would like to show the difference with an example: a two-page voorlopige aanslagprovisional tax assessment from the Belastingdienst.
A translation gives you two pages of text in your language. The sentences may well be translated correctly, but the text contains several dates, a large number of amounts and a calculation table. Working out which of them matter to you is left to you.
An explanation gives you the outcome of the letter directly: this letter sets out the estimated tax calculation for this year, the Belastingdienst will pay a certain amount every month for a certain period, you need to report any change in your income, and you have until a certain date to object to the estimate.
Where translation struggles
Official terms. In everyday language "aanslagtax assessment · In everyday language it means 'attack'" means "attack"; in a tax letter it means an assessment. In the dictionary "beschikkingadministrative decision" also has meanings such as "being available for use"; in an official letter it is used for an administrative decision. A translation that ignores the context can render these words wrongly.
Tables. Camera translation reads the text line by line. In tables of amounts the columns can get mixed up, and the amount to be paid may be impossible to tell apart from the amount already paid.
The last part of the letter. The right to object, the objection period and the address to send it to are usually in the last paragraph of the letter, in small print. A translation carries that part over too, but gives it no emphasis.
Letters of several pages. The decision may be on the first page, the calculation on the second and the objection form in an enclosure (bijlageenclosure). When the pages are translated one by one, the link between them can be lost.
Before you share the photo
A single page of an official letter holds a great deal of personal information: your name, your address, your BSNcitizen service number, often your IBANbank account number, and details of your income or debts. Many translation apps send the photo, or the text in it, to a server to process it. We recommend checking in the privacy settings how the app you use handles this data and whether it stores it.
The same applies when you send a photo of the letter to someone you know or to a messaging group. A copy of the photo stays on the other person's phone, in their backups and in the chat history. We have covered the risks of BSNcitizen service number misuse in a separate post.
If you do need to share the photo, we recommend covering the BSNcitizen service number, the IBANbank account number and any file numbers before you send it.
Letrin's approach
We built Letrin to meet both needs together: making the letter understandable and protecting personal information.
The text is read on the phone. Text recognition runs on the phone's own processor and the photo does not leave the phone. Several pages can be scanned as one letter.
Personal details are hidden on the phone. Name, address, BSNcitizen service number, IBANbank account number, phone number and file numbers are detected and hidden before anything is sent. The text to be sent is shown on a confirmation screen, where you can mark other parts you want hidden too. No data is sent without your approval.
The result is a structured explanation. The explanation is made up of these sections:
- the type of letter and the body that sent it,
- a short summary,
- what is being asked of you,
- the steps to take,
- dates and amounts,
- warnings to pay attention to.
Official Dutch terms keep their original form in the explanation, with their meaning in your language beside them. That way you recognise the same terms when you speak to the body.
Next steps. If the letter has a deadline, a reminder is set: 7 days before, 2 days before, and on the morning of the last day. If you need to reply, a draft in formal Dutch is prepared and shown with the translation next to it. The first draft reply for each letter is free.
Letrin is available in 19 languages. There is no need to create an account or give an email address, and the first explanations are free.
When a translation is enough
Not every letter needs a detailed explanation. For an event announcement, a waste collection calendar or general information, camera translation is enough. For letters that contain a decision, an amount or a deadline, the translation is the first step. What the decision means, whether the amount is correct and how long you have still need to be looked at separately.
Check it against the paper
Letrin's explanations are produced with AI and can contain mistakes. We recommend always checking dates and amounts against the original letter. Letrin does not give legal, tax or immigration advice; in a dispute, Juridisch Loket and the municipality's sociaal raadslieden give free help.
