Gegevens gecontroleerd · juli 2026
Who decides my IR35 status?
For medium and large clients, the client issues a Status Determination Statement and the fee-payer deducts tax at source. For small clients, your own company assesses status and operates the deemed payment if inside.

Alles over Off-Payroll Working (IR35)
📋Overzicht+
Models the 2025/26 deemed employment payment chain: the fee is grossed down for employer NIC (15%) and apprenticeship levy (0.5%), then income tax and employee NIC are applied. The outside route pays a £12,570 salary, corporation tax with marginal relief, and distributes the remainder as dividends.
💡 Best practices
- Employment Allowance cannot be used against deemed payments — employer NIC applies from the £5,000 secondary threshold.
- The outside-IR35 route assumes full profit distribution as dividends; retaining profit in the company defers dividend tax.
- Status is determined by working practices (control, substitution, mutuality of obligation), not by contract labels — check with HMRC's CEST tool.

FAQ — Off-Payroll Working (IR35)
Who decides my IR35 status?+
For medium and large clients, the client issues a Status Determination Statement and the fee-payer deducts tax at source. For small clients, your own company assesses status and operates the deemed payment if inside.
Why is employer NIC deducted from my rate inside IR35?+
The fee-payer's employer NIC (15% in 2025/26) and apprenticeship levy (0.5%) come out of the contract fee before the deemed payment is taxed, which is why inside-IR35 take-home drops sharply.
Is the outside-IR35 figure guaranteed?+
No — it is a simplified model (£12,570 salary, full dividend distribution, no expenses or pension planning). Actual results depend on your company's costs and remuneration strategy.
