Recommendations
File your 2024/25 return early
The sooner you file, the sooner you can gather your SA302 and apply for your mortgage. Don't wait until the January deadline.
Apply before your documents expire
Ensure your application is submitted and ideally completed before your tax documents reach their 18-month validity limit.
Allow buffer time
Mortgage applications typically take 3-4 months from application to completion. Factor this into your timeline.
