Understanding CIS Statements: How They Impact Mortgage Applications

The journey to homeownership can be both exhilarating and daunting. It’s a process filled with numerous financial evaluations, documentation checks, and evaluations. For many, the path is relatively straightforward, but for certain groups, like those self-employed within the construction sector, the process has its unique intricacies. One of the main challenges they face revolves around proving their income in a way that’s acceptable to mortgage lenders. For such individuals, the CIS (Construction Industry Scheme) statements become a crucial piece of the puzzle.

As essential as they are, many are still unclear about how these statements influence their chances of securing a mortgage, especially when aspiring to buy those more upscale, expensive houses on the market. So, what exactly are these statements, and why do they hold such significance in the mortgage application process? In this guide, we aim to shed light on the subject, helping you navigate the realm of CIS statements and their implications for mortgage applications with ease.

What are CIS Statements?


At its core, the Construction Industry Scheme is a tax deduction system, specifically designed for contractors and subcontractors within the construction industry in the UK. Under the scheme, contractors deduct money from the subcontractor’s payments and then pass it over to HM Revenue and Customs (HMRC). This system ensures that HMRC receives the taxes due from subcontractors in the construction industry.

Every month, the contractor provides the subcontractor with a CIS statement detailing the deductions made. This statement serves as an official record of the income the subcontractor has received and the tax that’s already been paid on their behalf.

Why are CIS Statements Important for Mortgage Applications?

  1. Proof of Income: If you’re self-employed, traditional payslips aren’t typically part of your financial records. Instead, your CIS statements serve as your proof of income. For a mortgage application, lenders want to be assured of your regular income and your ability to maintain mortgage payments over time.


  1. Demonstrating Financial Responsibility: By showing a history of consistent income and tax payments through your CIS statements, you demonstrate financial responsibility to potential lenders. This can be particularly persuasive if you’re seeking a larger mortgage for more expensive houses.


  1. Facilitates Self-Employed Mortgage Applications:For those in the construction industry, having an organised record of CIS statements can simplify the mortgage application process. Some lenders even offer specialised mortgage products tailored for those who can produce CIS statements, recognising the unique financial profile of subcontractors.

Potential Challenges

While the CIS statement can be a useful tool, there are some challenges to be aware of:


  1. Fluctuating Income:Unlike a fixed monthly salary, subcontractors might experience a more fluctuating income, which can concern some lenders. They might worry about the borrower’s ability to maintain consistent mortgage payments if their income varies significantly.


  1. Recent Changes in Income: If you’ve recently experienced a significant increase in your income, lenders may remain cautious. They’ll typically prefer to see a consistent income level over an extended period.


  1. Limited History: If you’ve only recently started working as a subcontractor or have gaps in your CIS statement records, this can raise red flags for lenders. They prefer a solid, consistent history of income and tax payments.


Tips for a Smooth Mortgage Application with CIS Statements


  1. Stay Organised: Regularly updating and maintaining your CIS statements will make the mortgage application process smoother. Ensure they are stored safely, and you can easily access them when needed.


  1. Consult a Specialist: Consider consulting a mortgage broker or advisor familiar with CIS mortgages. They can provide tailored advice and might know lenders more open to CIS statement-based applications.


  1. Plan Ahead: If you’re considering a mortgage in the near future, think about stabilising your income as much as possible. This might mean taking on more consistent contracts or being mindful of income fluctuations.


  1. Be Transparent: When talking to lenders, be open and transparent about your financial situation. If there are inconsistencies or gaps in your CIS statements, provide a clear explanation.


  1. Use Reputable Resources: Sites like [] offer invaluable insights into managing CIS statements effectively. Making use of such resources can help demystify the process and put you on a solid footing.


Impact of the Duration within the CIS on Mortgage Applications


Duration Matters: The length of time you’ve been part of the CIS can play a significant role in your mortgage application. Generally, mortgage lenders feel more confident in applicants who have a longer history within the CIS. This is because a lengthy track record can provide more robust evidence of consistent earnings and tax payments.


Establishing Trust: A longer duration in the CIS often translates to a more predictable income pattern. Lenders can use this history to anticipate your future earnings more reliably, fostering a sense of trust.


Overcoming Short-Term Fluctuations: Everyone can face short-term disruptions in income. However, if you’ve been part of the CIS for an extended period, these short-term fluctuations can be offset by your longer-term consistency, making lenders more understanding.


Potential for Better Rates: Some lenders might offer better interest rates or more favourable terms to those with a long-standing record within the CIS. They see these applicants as lower risk compared to someone new to the scheme.


It’s advisable to highlight your duration within the CIS when applying for a mortgage, especially if you’ve been a part of it for several years.

Wrapping Up

The property market can often feel like a maze, especially for those in unique employment situations such as subcontractors in the construction industry. However, knowledge is power, and understanding the role and impact of the CIS statement can significantly streamline the process. For many subcontractors, the dream of homeownership may initially seem riddled with complications, but with the right information, this dream can be realised. While the CIS statement can present its challenges, it also offers a gateway to prove financial stability and worthiness to potential lenders. By fully grasping the significance of CIS statements, meticulously organising them, and making informed decisions based on expert advice, you can elevate your chances of not just securing a mortgage but also landing your dream home, be it a cosy apartment or one of the more opulent, expensive houses on the market. As with any journey, understanding your tools and resources is the key to a successful outcome.
