What is IR35 (UK) / Article L.8221 (France) — Worker Classification?

Worker misclassification is EMEA freelancers' biggest legal exposure — French URSSAF claws back 5 years of employer charges (~45% of gross billings); UK IR35 puts status control with the end-client.

Am I inside IR35 as a SAP contractor?

Short answer above

Worker classification is the legal test that decides whether someone invoicing as a "consultant" is genuinely independent — bearing commercial risk, working for multiple clients, controlling their own methods — or is, in substance, a disguised employee who should be on the client's payroll. Getting the classification wrong is the single largest legal exposure a solo SAP analytics freelancer carries, because the consequence is not a civil dispute between two commercial parties but a tax authority reopening years of history and assessing unpaid employer social charges plus penalties, sometimes with criminal exposure attached.

The two operative regimes

Why it matters

Five France red flags compound: fixed hours, sole client 12+ months, client-only equipment, org-chart integration, no own commercial structure — all five present means automatic recharacterisation.
Since April 2021, the UK end-client determines IR35 status via the Status Determination Statement — a decision outside the consultant's control costing 25-35% of headline rate if wrong.
Genuine right of substitution is the strongest UK factor working in the consultant's favour — if you can send a substitute, that alone weighs toward outside IR35.

Key points

France Article L.8221: lien de subordination test; URSSAF 5-year recovery, ~45% gross + penalties + criminal.
UK IR35 (2021 reform): end-client SDS; inside IR35 = 25-35% loss via PAYE + NIC.
Five FR red flags: fixed hours · sole client 12mo+ · only client infra · org-chart integration · no commercial structure.
Defences: SASU/EURL (FR), Ltd PSC (UK), GmbH (DE) + multi-client + own infra + documented independence.
Portage salarial sweet spot: first 6-12mo or clients refusing freelance; ~10% management fee, full employee benefits.
Multi-client discipline: 2-3 concurrent, < 80% concentration beyond 18mo.
EMEA cross-border: FR most aggressive; DE DRV parallel; UK SDS regime; NL DBA reform.
Quarterly independence self-audit catches drift before audit.
IR35 (UK) / Article L.8221 (France) — Worker Classification is mastered only when it changes a named buyer decision.
