Outside IR35 contractors working through their own limited company hold the strongest position in the contractor mortgage market. Most specialist lenders assess you on your full contract value — no PAYE deductions, no company accounts required — but approach the wrong lender and you'll be measured on tax-efficient drawings instead, often less than half your true earning capacity. We make sure that never happens.
An outside IR35 determination means your engagement is genuinely one of self-employment for tax purposes — you invoice your client or agency through your limited company, the company receives the gross fee, and you decide how to draw income from it. No tax is deducted at source.
For mortgage purposes, this means the cleanest possible day rate assessment. The contract shows the gross rate; the company bank statements show the gross receipts; and the lender annualises the rate directly. There is no employer's NI adjustment, no umbrella margin, no PAYE complication. A contractor on £650 per day is assessed on £149,500 annualised — full stop.
Outside IR35 contractors have a choice — or rather, their broker makes a choice for them — between day rate annualisation and accounts-based assessment. For the typical contractor paying a modest salary and dividends, day rate annualisation produces a far higher figure. Consider a contractor on £650 per day drawing £13,000 salary and £45,000 dividends. Accounts assessment: £58,000 income, maximum mortgage £261,000 at 4.5 times. Day rate assessment: £149,500 income, maximum mortgage £672,750. Same person, same earnings, £400,000 difference in the offer.
The exception is contractors with substantial retained profit who want it recognised — a small number of lenders will assess salary plus net profit, which can compete with day rate assessment in specific cases. We run both calculations for every client and recommend the stronger route.
Provide your current contract showing the day rate, client details, and contract end date to support income assessment.
A CV or work history demonstrating continuity within your profession helps lenders assess the long-term stability of your income.
Recent personal and business bank statements are used to verify contract income and payment history.
Standard identity and proof of address documents are required to complete your mortgage application with specialist lenders.
Lenders prefer to see a reasonable remaining term on your current contract — typically at least one to three months — or a documented history of renewals. A contractor mid-way through a six-month contract with two prior renewals at the same client is an easy case. A contractor in the final two weeks of a contract with no confirmed renewal is harder, though not impossible.
Where your contract is approaching its end, a renewal email or extension letter from the client or agency strengthens the application considerably. We advise on application timing relative to your contract cycle to present the strongest possible position.
An outside IR35 determination depends on the working practices and contract terms of each engagement. Contractors moving between clients should be aware that a future inside IR35 engagement changes the mortgage assessment route — not catastrophically, with the right lender, but materially with the wrong one.
For contractors planning a property purchase in the next six to twelve months, the IR35 status of your current and next contract is worth factoring into timing. We advise on how upcoming engagement changes affect your mortgage options so there are no surprises mid-application.
Outside IR35 contractors who invest in property have a structural advantage: the limited company they already run can sit alongside an SPV for property investment, keeping trading and investment activity separate. BTL lenders assess the rental coverage first, with the contractor day rate satisfying any personal income requirement comfortably.
We advise on BTL strategy for outside IR35 contractors as part of the wider mortgage conversation, including the personal-versus-SPV ownership question that should always involve your accountant.
Working outside IR35 puts you in one of the strongest positions for a contractor mortgage—but only if your application is assessed using your contract day rate rather than salary and dividends. Speak to our specialist team for tailored advice and access to lenders who understand contractor income.
