Alles over Contractor IR35 Take-Home
📋Overzicht+
Runs the same annual contracting fee through both IR35 regimes for 2025/26. Inside IR35 the fee is taxed as employment income — income tax, employee NIC, and employer NIC borne through the fee. Outside IR35, your limited company pays a low director salary, deducts allowable expenses and employer NIC, pays corporation tax, then distributes the rest as dividends.
💡 Best practices
- Most of the outside-IR35 advantage comes from dividends escaping National Insurance — it narrows at higher fees as the 25% corporation tax main rate applies.
- This model is indicative — it excludes VAT/Flat Rate Scheme, the Employment Allowance and pension annual allowance tapering.
- Getting the IR35 determination wrong is costly: HMRC can recover unpaid tax, interest and penalties from the fee-payer or your company.
🔢 Concreet voorbeeld
£500 day rate over 220 billable days (£110,000 fee): the outside-IR35 route typically nets several thousand pounds more take-home than inside IR35, once salary, expenses and dividends are accounted for.

📚Woordenlijst+
- Inside IR35
- The engagement is treated as disguised employment — the fee is taxed as earnings, with income tax and employee NIC deducted, and employer NIC accounted for out of the fee.
- Outside IR35
- A genuine business-to-business engagement — your limited company pays corporation tax on its profit, then you extract the rest as a low salary plus dividends.
