# Valuation for a WOZ objection in Rotterdam: organise your file
For a WOZ objection in Rotterdam, check the decision, valuation reference date, property facts, evidence and six-week deadline.
For a WOZ objection in Rotterdam, start with the municipal decision and tax assessment. Check the valuation reference date, property description, comparison information and formal deadline. A separate valuation can help when the facts or evidence need deeper review, yet the municipality’s objection instructions remain the starting point.
If you are preparing a Rotterdam WOZ decision, keep the municipal assessment, reference date and property facts together.
## TL;DR
Use this file checklist:
1. Save the WOZ decision and tax assessment.
2. Write down the valuation reference date.
3. Check area, property type, condition, use and other facts.
4. Compare the municipal evidence with the home.
5. Submit the objection within six weeks from the date on the decision.
Follow the current form, address and submission instructions on the decision.

## Checklist overview
### What this covers
- reading a Rotterdam WOZ decision;
- checking the reference date and property facts;
- finding concrete differences in the tax record;
- deciding when extra valuation work may help;
- preparing a clear formal objection.
### Who can use it
Owners, tenants and other interested parties can use the checklist as general preparation. Rotterdam states that a tenant can also object to the WOZ value when it appears incorrect. Read the current notice and municipal instructions for your own position.
### What it cannot do
It does not decide whether your value is correct or predict the outcome. It does not replace advice about a personal tax, legal or procedural question.
## How to use the checklist
Save one folder with the decision, tax assessment, tax report, photographs, measurements, repair records and notes. Add the date you received the notice. Use the municipality’s current online instructions or the details printed on the decision.
Make a short timeline before collecting arguments.
## Phase 1: Read the decision
### Before you start
- [ ] Save the complete WOZ decision and tax assessment.
- [ ] Record the date printed on the decision.
- [ ] Note the WOZ value and the tax year.
- [ ] Find the municipality’s current objection instructions.
### Main checks
- [ ] Check the address and property type.
- [ ] Check the value reference date.
- [ ] Open the municipal tax report if available.
- [ ] Record the property area, plot area and building year shown.
- [ ] Note any stated outbuilding, parking, extension or other feature.
Rotterdam explains that the WOZ value uses a reference date of 1 January of the previous year. For the 2026 tax assessment, the city says the reference date is 1 January 2025. Use the date shown for your own assessment because the tax year can change.
### Common mistakes to avoid
- [ ] Do not argue only from the current asking price.
- [ ] Do not use a later renovation to describe the home at the reference date.
- [ ] Do not lose the printed deadline while researching.
## Phase 2: Check the facts
### Facts to compare
- [ ] Living area and plot area.
- [ ] Property type and building year.
- [ ] Maintenance and condition at the reference date.
- [ ] Extensions, outbuildings and parking.
- [ ] Location, noise, outlook and access.
- [ ] Ownership or use facts that affect the record.
### Evidence to collect
- [ ] Photographs showing condition at the reference date.
- [ ] Plans, measurements or permits that correct the file.
- [ ] Repair, damage or demolition records.
- [ ] Sales evidence for genuinely comparable homes.
- [ ] A clear note explaining each difference.
Write one fact per line. “The value feels high” is a starting feeling. “The tax report records an extension that was not present on the reference date” is a factual point that can be checked.
## Phase 3: Write the objection
### A clear structure
1. Identify the decision and property.
2. State the WOZ value you are challenging.
3. Explain the factual and valuation reasons.
4. Attach documents or identify where the municipality can check them.
5. Ask for a review and retain a copy of the submission.
### Deadline check
Rotterdam and the Waarderingskamer state that the objection period is six weeks from the date on the decision. The Waarderingskamer explains that the period normally starts on the day after the decision is dated, with publication and receipt rules that can matter in unusual cases.
Mark the final day in your calendar and submit early. If the date or receipt is unclear, contact the municipality or a qualified adviser promptly.
## Phase 4: Decide whether extra valuation work helps
You may be able to check and challenge a WOZ value yourself. The municipality and Waarderingskamer both point readers toward checking the record and contacting the municipality with questions.
Extra valuation work may help when the home has unusual condition, a clear measurement error, special rights, a major difference from the comparison homes or a question about a past date. A formal report still does not replace the written objection or deadline.
## Final checks before sending
- [ ] The correct municipality and decision are named.
- [ ] The property address and tax year match.
- [ ] Every factual reason has a document or clear explanation.
- [ ] The reference date is used consistently.
- [ ] The objection follows the current municipal instructions.
- [ ] The submission is sent within the six-week period.
- [ ] A copy and proof of submission are saved.
## A balanced view
A lower WOZ value can affect some municipal charges or other calculations. That effect does not prove that the municipal value is wrong. A useful objection needs a factual reason connected to the reference date and the property evidence.
## FAQ
### Can a tenant object to the WOZ value?
Rotterdam says a tenant can object within six weeks after the date on the decision when the value appears incorrect. Check the current municipal instructions and your own notice.
### What is the WOZ reference date?
It is the date used to value the property for the relevant tax year. Rotterdam says the date is 1 January of the previous year for its annual assessment, with separate rules for some changes in condition.
### Do I need a valuer for an objection?
No. You can first check the municipal information and contact the municipality. A valuer may help when the facts, date or evidence need a separate professional review.
### Can I object after six weeks?
Late objections can raise a legal question about admissibility. Contact the municipality or a qualified adviser quickly if you have missed or may miss the period.
### Does a mortgage valuation prove the WOZ value?
No. Mortgage and WOZ assignments can use different purposes, dates and conditions. Compare the question each report answers.
