An AI contractor using an umbrella company at £700/day (220 days = £154,000 gross contract value) typically takes home approximately £85,000–£92,000/year after umbrella fees, employer’s NI, income tax and employee’s NI. Umbrella companies are compulsory for most inside-IR35 contractors without a limited company. They handle all payroll admin but charge £15–£50/week. Compared to outside IR35 via limited company, the difference at £700/day is approximately £15,000–£25,000/year.
Based on 220 working days/year. FCSA-compliant umbrella. 2026-27 tax rates. Holiday pay shown separately (12.07%).

Pension tip: With a 5% salary sacrifice pension (£6,594/year), income tax falls by approximately £2,638. Net take-home is ~£85,812 after pension deduction, but your pension fund receives £6,594 — making the total effective value approximately £92,406 including pension. Salary sacrifice through your umbrella is the most effective tax mitigation available inside IR35.
Umbrella figures include holiday pay (12.07%). Inside IR35 assumes direct PAYE without umbrella fees. Outside IR35 via limited company. All estimates.

|---|---|---|---|
| £500/day | ~£60,000 | ~£65,000 | ~£78,000 |
| £700/daymedian | ~£88,000 | ~£92,000 | ~£108,000 |
| £1,000/day | ~£117,000 | ~£122,000 | ~£150,000 |
Umbrella is slightly lower than direct PAYE inside IR35 due to umbrella fees and employer NI being deducted from the contractor’s rate rather than paid on top by a direct employer. Outside IR35 via limited company is significantly higher due to the corporation tax and dividend tax treatment. All figures are estimates.
Only use umbrella companies accredited by the FCSA (Freelancer & Contractor Services Association) or Professional Passport. HMRC actively pursues non-compliant umbrella schemes. Avoid any umbrella that promises unusually high take-home percentages — these almost always involve disguised remuneration, which HMRC investigates and issues large retrospective tax bills for.
Legitimate umbrella companies charge a flat weekly or monthly fee (£15–£50/week). The fee covers payroll processing, employment liability insurance, and statutory benefits administration. Be wary of percentage-based fees or complex structures. Any umbrella offering take-home above ~65% of gross contract value at higher income levels is almost certainly running a non-compliant scheme.
Umbrella employment gives you statutory sick pay (SSP), statutory maternity/paternity pay, holiday pay (12.07% of earnings), pension auto-enrolment, and employer liability insurance. These have real financial value compared to operating a limited company where you must self-fund these protections. Factor this into your cost comparison, especially if you value sickness cover.
