SA302 and Tax Year Overview Guide

Caz Blake-Symes • February 15, 2021

Information needed for self employed clients

If you receive any income from being self employed including property rental income, we will need proof of income when preparing your mortgage application. Below is a brief guide about the documentation that we will require.
What is my SA302 and Tax Year Overview?
The SA302 is a summary of the income that has been reported to the HMRC. It is a response from HMRC which is only issued to those who submit a tax return before 31 October (for paper returns) or 31 January (for online returns) following the end of the tax year.
The form shows your income for the year and how much tax you owe. It is effectively a certificate that documents exactly how much income you have declared, therefore the form is an easy way for a lender to verify that the income on a mortgage application is the same as you have shown to HMRC.
An additional document called a Tax Year Overview verifies that the SA302 information is correct. It is produced by HMRC once you have submitted your self-assessment tax return and shows the amount of tax due to be paid direct to HMRC or any available amount for refund for a given tax year.
We recommend if you do not already have your SA302 and Tax Year Overview and intend to submit these as part of your mortgage application, you do so at the start of the application process as they can take a number of weeks to obtain. To ensure the loan is affordable, during the application process we require you to send both documents together.
How to get your SA302 and Tax Year Overview
If you or your accountant submitted your tax return online, you can log into your HMRC online account to obtain your forms. 
If you or your accountant submitted a paper tax return, you should automatically be sent these in the post in response to this.
If you have lost your paper forms, or you can’t access your HMRC online account, you will need to contact HMRC. You can do so by calling them on 0300 200 3310. They will ask for your National Insurance number and Self-Assessment Unique Taxpayer Reference (UTR) so it’s best to have them to hand when you phone.
The documents will take up to two weeks to arrive, so we recommend getting this done at the beginning of the application stage, ensuring you have it ready when you need to send it off to your lender.
Accessing your Government Gateway account
HMRC are using the Government Gateway portal for more and more information and all businesses and those filing self-assessments are required to have a Government Gateway account. The process is relatively straightforward and simple to set up.
If you have any queries whatsoever please contact your Adviser or one of our experienced Admin team who will be delighted to help you.

Adapted from Zoopla’s April 2025 Housing report I mage: The analysis uses average house prices from the house price index and for first-time buyers to assess mortgage payments at different mortgage rates applied to a 30- year mortgage, at different loan-to-values. One emerging trend that we expect to positively support market activity in the coming months is a relaxation in how lenders assess the affordability of new mortgages. While buyers focus on the mortgage rate they will pay, lenders also check whether the borrower can afford a 'stressed mortgage rate' at a higher level than the borrower will pay. ​ While the average 5-year fixed rate mortgage is around 4.5% today, many lenders are currently 'stress testing' affordability at 8-9%. This makes it harder to secure a mortgage without a large deposit. If average mortgage stress rates were to return to pre-2022 levels of 6.5% to 7%, this would deliver a 15-20% boost to buying power. ​ An average first-time buyer with mortgage repayments of £1,020pcm at a 4.5% mortgage rate would typically have to prove they could afford monthly repayments of £1,550pcm at an 8.5% stress rate. If the stress testing is relaxed to 6.5%, repayments would fall to £1,275pcm, boosting buying power. It's a similar pattern for the average homeowner, while the actual impact will vary by lender and type of borrower. ​ This change would consequently supporting demand and sales volumes, helping to clear the stock of homes for sale, rather than boosting house prices. Other existing rules and regulations that remain in place will continue to impact the availability of mortgage finance.  Comment from Phil Clark “This is potentially very exciting news and will give borrowers a greater choice of products if these rules are relaxed. Regardless of whether you are a First-time Buyer, Looking to move, remortgage or invest in property, there are a huge range of competitive mortgage deals on the market. I will be delighted to discuss your specific requirements and offer you the most suitable deal!” Please call Phil on 0117 3251511 or email info@swmortgages.com For more information about the Mortgage and Protection products we offer, please visit www.bristolmortgagesonline.com Your home/property may be repossessed if you do not keep up repayments on a mortgage or other debt secured on it.
