How Lenders Calculate Contractor Income
The most contractor-friendly income assessment method is day rate annualisation. Under this approach, your daily contracted rate is multiplied by five days per week and 46 weeks per year, giving a figure that accounts for a typical number of working weeks after holidays and between contracts. For example, a day rate of £400 would produce an annualised income of £92,000 using this calculation.
Not all lenders use this method. Some will revert to tax returns or payslips as their primary income evidence, which can produce a much lower assessed income — particularly if your accountant has legitimately reduced your taxable income through allowable expenses. It is therefore essential to identify lenders who explicitly use day rate annualisation before applying.
The length and status of your current contract is also a material factor. Most lenders will want to see that you have at least three months remaining on your current contract, or evidence of a signed renewal. A strong track record of continuous contracting, demonstrated through previous contracts, adds further confidence for the underwriter.
PAYE Contractors, Limited Companies and Umbrella Companies
The vehicle through which you contract makes a material difference to how lenders assess your income. PAYE contractors — those paid directly through the end client or agency with tax deducted at source — are typically treated most similarly to standard employed borrowers. Lenders can use payslips in the usual way, making the process relatively straightforward.
Contractors who operate through their own limited company (sometimes called a personal service company, or PSC) will generally be assessed on salary and dividends, though day rate annualisation is also available with specialist lenders. Umbrella company contractors, who operate through a third-party payroll provider, will have payslips available but these often show a range of deductions that can make the net figure appear lower than the contracted rate.
IR35 status is increasingly relevant for contractors who work through a limited company. Where HMRC deems a contractor to be inside IR35, they are effectively treated as employees of the end client for tax purposes. This may mean more tax is deducted at source, and lenders will take this into account when assessing net income. Some lenders may request confirmation of your IR35 status as part of the application process.
For umbrella company workers, providing the contract of engagement alongside payslips can help lenders understand the relationship between your contracted day rate and the take-home pay shown on your payslips, which can support a higher assessed income figure.
