Self-Employed Mortgage Documents Guide

If you are self-employed, securing a mortgage can sometimes feel more challenging than it does for someone in traditional employment. At Bolt Mortgages, we want to make the process as clear and straightforward as possible.

In this episode, Anthony McQuilliam explains which documents you need to gather, the differences between trading as a sole trader or a limited company, and how far in advance you should start preparing for your application to ensure everything goes smoothly.

What documents do self-employed borrowers need to provide for a mortgage application?

To start your application, you will need proof of ID, such as a passport or driving licence. You also need to prove your income, which varies depending on your business setup. Generally, you should prepare your last four months of bank statements for both your business and personal accounts, proof of your deposit, and a recent credit report.

If you are a sole trader, you typically need your last two years of tax calculations and tax year overviews. Limited company directors usually need those same tax documents plus their most recent two years of limited company accounts. However, some lenders are willing to work with just one year of records.

Is there a difference between what sole traders need to provide versus limited company directors?

While much of the paperwork is similar, limited company directors have extra requirements. If you own a limited company, you must provide your yearly company accounts in addition to your personal tax calculations and tax year overviews. You will also need to show four months of business bank statements, which are not required for those not set up as a limited company.

How many years of accounts or tax returns do most lenders ask for?

Lenders prefer to see the last two years of tax calculations, tax year overviews, and limited company accounts. Having two years of records available gives you access to a wide range of mortgage products and competitive rates.

If you have only been trading for one year, or if your most recent year was significantly more profitable, there are lenders who may still be able to help. It is worth keeping in mind that the interest rates may be slightly higher than those available on standard mortgage deals.

What is an SA302 and how do you get one from HMRC?

An SA302 is a document that confirms your total earned income for a specific tax year. If you have an accountant, they can easily produce this for you, along with your tax calculation and tax year overview.

If you do not have an accountant, you can get these documents yourself by accessing the HMRC Government Gateway. You can then download the relevant documentation and send these across to your mortgage advisor to prove your earnings.

Can an accountant’s certificate be used instead of full tax returns?

In many cases, lenders will not accept an accountant’s certificate by itself. Instead, they use it to support your tax returns if there are any unusual figures or anomalies that need explaining.

While this can be useful in supporting your tax calculations and tax year overviews, you will still be required to provide the full tax documentation.

Do lenders accept tax year overviews as well as SA302 forms?

SA302s are no longer the standard documents used for mortgage applications.

Instead, lenders will usually ask for your tax calculations and tax year overviews, as these are the documents used to confirm your income.
