Sole Trader vs Limited Company — How Each Structure Is Assessed
Sole trader shop and business owners are assessed on net profit — turnover minus allowable business expenses as declared on the self-assessment return. This figure is typically straightforward to calculate and appears clearly in the SA302. The challenge is ensuring that the net profit figure accurately reflects the business's real earning power. Where significant legitimate expenses have been claimed — particularly for trades with high material or stock costs, or where a vehicle is used substantially for business — the net profit figure may be considerably lower than the business's actual cash generation for the owner.
Limited company owners have more complexity. The most common income structure for a small limited company owner is a director's salary set at or near the National Insurance threshold (currently £12,570 per year) topped up with dividends from the company's post-tax profits. This is tax-efficient but creates an income picture that needs careful lender assessment. A lender who simply looks at the director's payslip salary will see £12,570 and dramatically undervalue the owner's true income. The correct approach is to add salary and dividends together as the total personal income drawn from the business.
Some lenders go further by also considering retained profit within the company — money left in the business that could have been drawn but was not. This recognition is important for business owners who deliberately leave capital in the company for reinvestment, working capital, or future corporation tax efficiency. Not all lenders will count retained profit, but those who do can significantly improve the income figure used in affordability, directly increasing borrowing power.
For business owners who have multiple companies — a common arrangement where related business activities are structured in separate entities — lenders will typically want to see accounts and income evidence for each entity that contributes to the owner's personal income. A clear accountant's summary showing total personal drawings across all companies can simplify the presentation considerably.
Add-Backs — What They Are and Why They Matter
Add-backs are adjustments made to a business's declared net profit figure to account for costs that reduce taxable income but do not represent ongoing cash outgoings from the business. The most common add-back in small business mortgage applications is depreciation. When a business buys equipment, vehicles, or other long-term assets, the cost is depreciated over several years in the accounts — reducing declared profit each year even though the actual cash was spent once. Adding depreciation back to net profit gives a more accurate picture of the business's ongoing cash earnings.
Other potential add-backs include one-off professional fees (legal costs, restructuring costs, or other exceptional expenses that are not expected to recur), amortisation of goodwill, and owner's salary if structured differently from standard drawings. The specific add-backs available and the proportion that lenders will accept vary between providers. Some lenders apply add-backs generously; others are highly conservative. A broker who regularly handles small business owner mortgages will know which lenders have the most favourable add-back policies for your specific accounts structure.
It is important to note that add-backs must be genuinely justifiable. Attempting to add back costs that are regular, recurring business expenses — rather than non-cash or one-off items — is something lenders and their underwriters will scrutinise carefully. The aim is to present an accurate picture of sustainable cash earnings, not to inflate the income figure artificially.
Working with an accountant who has experience preparing accounts for mortgage purposes is extremely valuable. The accountant can identify legitimate add-backs, present them clearly in the accounts or in a supplementary letter, and explain the business's financial structure in a way that helps the lender's underwriter reach a swift and favourable decision. This professional presentation can make a meaningful difference to the outcome of a small business owner's remortgage application.
