How Lenders Assess Bonus Income
Bonus income is treated as supplementary to your basic salary by virtually all UK mortgage lenders. While your base pay forms the foundation of the affordability assessment, bonuses can provide a meaningful uplift to your borrowing capacity if they are presented correctly.
The key factors that lenders consider when assessing bonus income include:
- Regularity - How frequently you receive bonuses. Annual bonuses paid consistently each year are viewed more favourably than one-off or sporadic payments
- Consistency - Whether the bonus amount has been broadly similar year on year, or whether it fluctuates significantly. Stable bonus levels are preferred
- Track record - How many years you have been receiving bonuses. A longer history provides more confidence that the payments will continue
- Proportion of total income - Some lenders cap the bonus element at a percentage of your total income, typically between 25 and 50 per cent
Most lenders will count between 50 and 100 per cent of your average bonus over the last one to three years. The percentage they use depends on their individual policies and how confident they are in the ongoing nature of your bonus payments.
Some lenders take a straightforward approach and simply average your bonus over two or three years, then apply a discount of around 50 per cent to account for the risk that future bonuses may be lower. Others may use a more sophisticated analysis that considers the trend in your bonus payments over time.
A small number of lenders will use your P60 as the primary income evidence, which includes all bonus payments. This can be advantageous because it captures your total actual earnings without the need for separate calculations about the bonus element.
It is important to understand that even within the same lender, the treatment of bonus income can vary depending on your industry, role and the nature of the bonus scheme. Bonuses in heavily regulated industries such as financial services may be treated differently from those in other sectors.
Types of Bonus Income and How They Are Treated
Not all bonuses are created equal in the eyes of mortgage lenders. The type of bonus you receive affects how it is categorised and assessed during the remortgage application process.
Annual performance bonuses are the most common type and are generally well accepted by lenders. These are typically paid once a year based on individual, team or company performance. Lenders will want to see evidence of bonuses received over two to three years and will usually average the amounts to arrive at a sustainable figure.
Quarterly or monthly bonuses tied to specific targets or metrics can actually be viewed more favourably than annual bonuses because they provide more frequent data points. If you receive regular quarterly bonuses, twelve months of payslips will show four separate bonus payments, giving the lender a clear picture of your typical bonus earnings.
Guaranteed bonuses, sometimes offered as part of a recruitment package for the first year or two of employment, are treated very favourably. Because they are contractually guaranteed, some lenders will count them at 100 per cent without any discount. However, lenders will also want to know what will replace the guaranteed bonus when it expires.
Discretionary bonuses are at the employer's discretion and are not guaranteed. These are treated more cautiously by lenders, who recognise that they may not be paid in future years. A consistent history of receiving discretionary bonuses helps, but lenders may still apply a steeper discount.
Profit-sharing and equity bonuses can be more complex for lenders to assess. Profit-sharing payments depend on company performance, while equity-based bonuses such as share options or restricted stock units involve valuation complexities. Not all lenders will consider these types of bonus, so specialist advice is recommended.
Sign-on or retention bonuses that are one-off payments are generally not counted by lenders because they are not recurring. While they may boost your income in the year they are paid, lenders recognise that they will not continue and therefore do not include them in the ongoing affordability assessment.
Evidence Required for Bonus Income
Providing comprehensive evidence of your bonus income is critical to ensuring it is properly considered in your remortgage application. The more thorough your documentation, the more likely the lender is to accept your bonus at a favourable level.
The standard documents you should prepare include:
- Payslips showing bonus payments - These should clearly show the bonus as a separate line item. If your bonus is paid annually, you will need the payslip from the month it was paid for each of the last two to three years
- P60 annual tax summaries - These show your total earnings for each tax year and are useful for confirming the overall contribution of bonuses to your annual income. Provide P60s for the last two to three years
- Employment contract - This should detail your bonus scheme, including the target bonus level, frequency of payment and any conditions that must be met for the bonus to be paid
- Bonus award letters - If your employer provides formal notification of bonus awards, these can serve as additional evidence of amounts and regularity
- Employer confirmation letter - A letter confirming your participation in the bonus scheme, recent bonus history and the expected continuation of the scheme
If your bonus has varied significantly from year to year, it is helpful to provide context for the variation. For example, if one year was unusually low due to a company restructure or an exceptional circumstance, an explanation can help the lender take a more balanced view rather than using the lowest figure.
For equity-based bonuses such as share options or restricted stock units, you may need to provide additional documentation including share vesting schedules, exercise statements and current share valuations. Not all lenders will consider these, so check in advance whether your chosen lender accepts equity-based compensation.
Some lenders may also want to see your bank statements showing the bonus payments being credited to your account. This serves as independent verification that matches the figures shown on your payslips and provides an additional layer of evidence.
