Belgium is introducing new rules for cross-border workers starting on August 17, 2026, changing the procedures and documentation required depending on the worker’s nationality and country of residence. The new framework simplifies the process for EU citizens while introducing new requirements for non-EU nationals, including the replacement of Annex 15 with Annex 64 for workers residing in France, the Netherlands, Germany, or Luxembourg. The changes also introduce a specific visa route for non-EU nationals residing in the UK.
The following outlines the key changes and the practical steps employers and cross-border workers should take ahead of the new rules taking effect.
Who Is Considered a Cross-Border Worker?
- Cross-border worker: someone who works in Belgium but keeps their main residence abroad and regularly travels between Belgium and their country of residence.
- Cross-border workers are not registered in the Belgian National Register.
New Requirements by Worker Category
1. EU Citizens
- No longer need to report to the municipality.
- Can enter and leave Belgium for work with a valid ID card or passport.
- Annex 15 will no longer be issued.
- If they move their main residence to Belgium, the normal EU residence procedure applies.
- They may still request a BIS number if needed.
2. Non-EU Nationals Living in France, the Netherlands, Germany, or Luxembourg
- Must apply through the municipality where they work in Belgium.
- Applies to:
- Employees
- Self-employed workers
- Posted workers
- They will receive an Annex 64 instead of Annex 15.
- Annex 64:
- Is not a residence permit.
- Only allows entry into and exit from Belgium for cross-border work.
- Does not create a Belgian right of residence.
- Validity is linked to the work/professional authorisation and is generally limited to maximum 1 year.
- It cannot exceed the validity of the passport or residence permit issued by the neighbouring country.
- The worker must confirm that their main residence remains in the neighbouring Member State.
3. Non-EU Nationals Living in the United Kingdom (Including UK Nationals and Third-Country Nationals)
- Must apply through the competent Belgian embassy or consulate in the UK.
- If approved, they receive a D visa B63.
- The visa does not grant residence rights in Belgium.
- No municipal application or registration is required.
Renewal of Annex 64
- Possible if the worker still meets the cross-border worker conditions.
- The same supporting documents as for the first application must be submitted.
Transitional Period
- Existing Annex 15 documents issued under the old system remain valid for a 12-month transitional period.
Practical Actions from August 17, 2026
For non-EU nationals living in France, the Netherlands, Germany, or Luxembourg:
- Apply for Annex 64 for new cases.
- Existing Annex 15 holders will eventually need to move to Annex 64 under the new system.
- Main documents required:
- Valid passport
- Valid residence permit from the neighbouring country
- Declaration confirming main residence remains abroad
- Proof of professional activity in Belgium:
- Employee: work permit / authorisation to work
- Self-employed: professional card
- Posted worker: work authorization or A1 certificate
For cross-border workers living in the United Kingdom, including UK nationals and third-country nationals:
- Apply for a D visa B63 through the competent Belgian embassy or consulate in the UK.
- Begin the visa application process as soon as possible, as appointment availability may be limited.
