This skill walks the assembly of work-history evidence for the Belgian nationality declaration under article 12bis of the Code de la nationalité belge [code-nationalite-12bis]. The evidence is one of the four alternative routes for satisfying the integration-evidence requirement under CNB art. 12bis §1, 2° (the standard 5-year residence route). The user demonstrates at least 5 years of legal Belgian employment within the period of legal residence; mixed salaried + self-employed counts cumulatively.

Scope. Component skill consumed by nationality-application and by integration-evidence (Route 4). Walks the document-assembly process, not the underlying employment / self-employment activity itself. Out of scope: regularising past undeclared employment (separate procedure under Belgian labour law).

Statutory basis

CNB art. 12bis §1, 2° lists four alternative integration-evidence routes; Route 4 is the 5+ years of legal employment. The threshold is cumulative within the user's legal-residence period. The implementing detail (what counts as "legal employment", how periods are calculated) lives in the SPF Justice circular implementing CNB art. 12bis. # unverified — current circular not pinned in this walk; verify against justice.belgium.be.

Salaried employment:

  • Belgian employment contract (Dimona-declared by the employer — every legal employment is captured in BCSS / ONSS / RSZ data).
  • Annual fiscal fiche (281.10 form) issued by the employer.
  • Avis d'imposition / tax assessment showing taxable employment income for each year.

Self-employment:

  • BCE / KBO active business-number registration with documented commercial activity.
  • Caisse d'assurances sociales pour travailleurs indépendants (CASTI) affiliation with paid social-security contributions.
  • Avis d'imposition showing self-employed income (declared on the relevant tax forms).

Mixed employment is accepted — a user with 3 years salaried + 2 years self-employed satisfies the threshold cumulatively. Verify per case with the commune.

Periods of involuntary unemployment sometimes count under retention rules:

  • For EU citizens: under EU 2004/38 worker-status retention, a user who lost employment after 12+ months of work and registered with the regional employment service (Actiris / VDAB / FOREM / ADG) retains "worker" status during the unemployment period for residence-rights purposes. Whether this counts toward the CNB art. 12bis §1, 2° "5 years of employment" threshold is operational — typically yes for EU citizens, but verify per case.
  • For non-EU citizens: the rules are narrower; typically a brief unemployment period within continuous residence does not break the file but does not count as "employment" toward the 5-year threshold either.

Pre-residence employment in another country does NOT count — only Belgian-territory legal employment.

The mycareer.be authoritative source

The single most useful evidentiary instrument is the mycareer.be lifetime career view (operated by SFP / BCSS). Authenticated with eID + card reader or Itsme, the portal shows:

  • Year-by-year employment timeline with employer names, period worked, employer-side declarations.
  • Self-employment periods with BCE / KBO references and CASTI contributions.
  • Unemployment periods with ONEM / RVA registration data.
  • Cross-EU career data (where the user has worked in other EU Member States with portable social-security rights).

Print the lifetime view as a PDF; this is the primary document the commune accepts. Most communes do not require additional employment-side evidence when the mycareer.be extract is comprehensive and clean.

Required documents

Primary

  • Mycareer.be lifetime career extract as a printed PDF or commune-portal-uploaded PDF. Date of extraction matters; extract within 1-3 months of the commune appointment.
  • Identity document + Belgian residence document.
  • NISS (niss-bis-attribution).

Supplementary (when mycareer.be has gaps)

For old-employment gaps:

  • Old payslips and fiscal fiches (281.10) for years not covered by mycareer.be.
  • Employer attestations confirming employment dates, role, and language of work (the latter is useful for language-knowledge-evidence).
  • Old Dimona declarations retrieved by the employer at the user's request.

For self-employment-period gaps:

  • BCE / KBO active-period reports showing business-number activation and deactivation dates.
  • CASTI contributions statements for each self-employed year.
  • Tax assessments showing self-employment income.

For involuntary-unemployment gaps (EU citizens):

  • ONEM / RVA registration history showing dates of unemployment registration and reasons.
  • Job-search activity records confirming reasonable engagement with the employment service.

Process

  1. Pull the mycareer.be extract as the starting evidence file.
  2. Review for gaps — every year between first commune registration and the present should show employment / self-employment / documented protected-status (e.g. parental leave, illness, retention-of-worker-status).
  3. Compute cumulative employment years within the legal-residence window. Cumulative ≥ 5 satisfies the threshold.
  4. Fill gaps with supplementary evidence where mycareer.be is incomplete (typically for periods before BCSS data centralisation maturity, late 1990s and earlier).
  5. Assemble the bundle as a coherent narrative: timeline + supporting documents per period.
  6. Present at the commune as part of the broader nationality dossier (nationality-application).

Known surprises

  • Mycareer.be is rarely complete back to 2000s onward. For users with 5+ years of recent Belgian employment, mycareer.be alone usually suffices. For users with longer tenures (10+ years) the older records may be incomplete; build supplementary evidence proactively.
  • Self-employment periods less reliably captured. Salaried employment is captured at Dimona-event level; self-employment is captured at CASTI-affiliation level which can have transition gaps. Verify periods of self-employment against CASTI directly if mycareer.be is sparse on those years.
  • Old employer-side records may be hard to retrieve. Belgian employers retain payroll records for limited periods (10 years for fiscal purposes; longer in some industries). A user trying to document employment from 15+ years ago may face employer-side retention gaps.
  • The ≥ 5 years threshold is cumulative, not continuous. A user who worked 2 years, took 1 year off (e.g. parental leave), then worked 4 more years has 6 years of employment — satisfies the threshold despite the gap. The "of which 5 years" framing in the CNB is cumulative.
  • Domestic-worker employment under specific regimes. Workers under the titres-services regime (cleaning, child-minding) are captured in mycareer.be; informal cash work is not. A user whose work history is largely informal will have a thin mycareer.be profile and limited Route 4 prospects.
  • Cross-EU career data via portable social-security. EU citizens with prior employment in other EU Member States may have data merged into mycareer.be via the EU-wide social-security data exchange. The Belgian work-history is what the CNB requires (Belgian-territory employment), but the merged view may help orient the file.
  • Tax-assessment-side evidence is corroborating, not primary. Tax assessments confirm income but don't on their own establish employment legality (someone with declared self-employment income could be operating without proper BCE / CASTI cover). The BCSS / ONSS data via mycareer.be is the authoritative employment source.
  • Employment in a non-Belgian-language environment counts for Route 4 employment but NOT for language-knowledge-evidence Route 4. A user employed at an English-language NGO for 5 years has the work-history evidence but separately needs to demonstrate language knowledge (Selor / parcours / diploma).

Verify with

  • mycareer.be: mycareer.be for the lifetime career extract.
  • SPF Justice — nationality declaration: justice.belgium.be.
  • CNB art. 12bis: Justel.
  • Caisses d'assurances sociales (Acerta, Securex, Partena, Liantis, etc.) for self-employed users' direct CASTI records.
  • integration-evidence for the broader four-route evidence framework that this skill feeds into as Route 4.
  • language-knowledge-evidence for the parallel language-knowledge requirement.

Verify with the commune before relying on this skill — evidentiary thresholds vary in nuance per file.
