Working inside IR35 means your income is taxed at source as if you were an employee — PAYE income tax and National Insurance are deducted before you are paid. What it should not mean is a smaller mortgage. Yet that is exactly what happens to thousands of inside IR35 contractors every year, because their applications are assessed by lenders who use net take-home pay instead of the gross contract value.
Consider an inside IR35 contractor on £550 per day. The gross annualised contract value on the 46-week calculation is £126,500. At 4.5 times, a gross-assessment lender can offer up to £569,250.
The same contractor's net take-home — after employer's NI, income tax and employee's NI — might be around £80,000 per year. A net-assessment lender at 4.5 times offers up to £360,000. The difference between the two approaches is over £200,000 of borrowing capacity on identical earnings.
This is not an edge case. It is the standard experience of inside IR35 contractors who approach the wrong lender, and the standard correction we make when those contractors come to us after a disappointing offer elsewhere.
Inside IR35 mortgage applications require evidence of the gross contract value as well as the standard payslip evidence. The core documents are: your contract or assignment schedule showing the gross day rate; your most recent three payslips showing PAYE deductions; your P60 for the most recent completed tax year; and three to six months of bank statements.
If your contract document does not clearly show the gross rate — common where the umbrella or agency paperwork focuses on the net arrangement — a confirmation letter from the agency stating the gross engagement rate is usually sufficient. We help you obtain this in the format the lender requires.
Being inside IR35 doesn’t have to reduce your mortgage options. Specialist lenders focus on your gross contract value rather than your reduced PAYE take-home, giving a more accurate view of your earning capacity.
Specialist lenders assess affordability using your annualised gross contract value instead of your lower net PAYE income.
Income tax, National Insurance, and other payroll deductions are recognised as part of the inside IR35 payment structure and don't necessarily reduce your borrowing potential.
Using your gross day rate can significantly increase the mortgage amount available compared with lenders who rely on net take-home pay.
We match your application with lenders who understand inside IR35 contracting and apply the most suitable income assessment method for your circumstances.
Many contractors have moved from outside to inside IR35 in recent years as end clients reassessed engagements under the off-payroll rules. A status change mid-career raises two practical mortgage questions: how lenders view the income history across the change, and which assessment method applies now.
For lenders using gross contract value assessment, a move inside IR35 with the same or similar day rate has minimal effect on borrowing capacity — the gross figure is broadly unchanged. The income history across the status change demonstrates continuity of earnings, which works in your favour. We frame the transition clearly in the application so the lender sees a consistent contracting career rather than a disruption.

Contractors whose original mortgage was arranged while outside IR35, and who have since moved inside, often worry that remortgaging will trigger a less favourable reassessment. The concern is legitimate with the wrong lender — but a full remortgage to a gross-assessment lender typically maintains or improves the position.
Where a fresh affordability assessment is genuinely unattractive — for example, where the day rate has also fallen — a product transfer with the existing lender avoids reassessment entirely. We compare both routes and recommend the one that protects your position best.
We'll assess your gross contract value and match you to the lender whose methodology works best for you — so you know exactly what you could borrow before you apply.
