Genuine Outside-IR35 Contracts, Defended
Independent contract reviews against the Ready Mixed Concrete, Autoclenz, and PGMOL tests — not a tick-box CEST run by someone who's never read the case law.
Who we helpAudience
IR35 Contractors accounting, handled.
A blanket "inside IR35" determination from your end client can cost you a third of your day rate — unless someone pushes back.
Since the April 2021 off-payroll reforms, most medium and large end clients issue a Status Determination Statement before you even sign. Too many are lazy, risk-averse cut-and-pastes that ignore your actual working practices. We review contracts, working-practice questionnaires, and CEST outputs — then build the evidence pack that gets a fair determination and keeps your PSC viable.

Our impact
How we help ir35 contractors succeed.
01 02 Challenge a Lazy SDS
When an end client throws you 'inside' on a determination that doesn't reflect reality, we draft the client-led dispute under Chapter 10 — most get reversed when properly evidenced.
03 Mixed Inside/Outside Income, Cleanly
Run an outside contract through your PSC while a deemed-employment payslip hits your personal tax — we structure the salary/dividend mix around the umbrella income.
04 Investigation-Ready Records
If HMRC opens an enquiry, your contract, SDS, working-practice notes, and substitution evidence are already filed — not scrambled together after the brown envelope arrives.
Tailored services
Everything you need for ir35 contractors.
01 Contract Reviews (Pre-Signature)
Line-by-line review of upper/lower contracts before you sign — mutuality, substitution, control, financial risk, exclusivity.
02 SDS Disputes Under Chapter 10
Drafted, evidenced disputes against an end client's inside determination, escalated through the client-led process.
03 Working-Practices Confirmation Notes
Sector-aware questionnaires that document the reality of how you actually deliver — the bit HMRC weighs heaviest.
04 PSC Setup, Closure & MVL Planning
When a contract goes inside long-term, we model whether to keep the company open, strike it off, or wind it up under an MVL for BADR.
05 Umbrella vs PSC Income Modelling
Honest take-home comparisons including Employer's NIC, apprenticeship levy, and umbrella margin — no spreadsheets that quietly forget the costs.
06 Year-End Accounts & Corporation Tax
Full PSC accounts, CT600, dividend vouchers, and director self-assessment — handled together so nothing falls between the cracks.
