Tax Year Overviews: What They Are and Why You Might Need One
If you’re applying for a mortgage, loan, or other type of finance, the lender will often ask for proof of your income. Many self-employed people assume their tax return is enough — but lenders usually want a Tax Year Overview (TYO) as well.
What is a Tax Year Overview?
A Tax Year Overview is a document you can download from HMRC’s online system.
It shows:
- Your declared income for the year
- The tax you owe (or have paid)
- Confirmation that your Self Assessment matches HMRC’s records
Why Do Lenders Ask for It?
Banks and mortgage providers want reassurance that:
- Your income figures on the mortgage application match your official HMRC record
- Your Self Assessment tax return has actually been filed
- Any tax owed has been paid or arrangements are in place
👉 In short, it’s an official stamp of credibility.
Tax Calculation vs Tax Year Overview
Here’s where people get confused:
- Tax Calculation (SA302): This shows how your tax was calculated, based on your income and expenses.
- Tax Year Overview (TYO): This confirms HMRC has accepted that calculation and records the tax position.
Lenders usually ask for both documents together.
How to Get a Tax Year Overview
- Log in to your HMRC online account.
- Select the tax year you need.
- Download and save the “Tax Year Overview” PDF.
- Provide it to your lender alongside your SA302.
If you use an accountant (like me), I can help access and supply these documents quickly. I’ve had to provide a lot of these recently.
Why Get Professional Help?
While you can download these yourself, mistakes are common — for example:
- Sending only the SA302 but not the overview
- Sending the wrong tax year
- Missing figures that don’t match the return
An accountant ensures you provide the correct documents, so your mortgage or loan application isn’t delayed.
Final Thoughts
If you’re self-employed and applying for finance, don’t get caught out. Lenders almost always want both the SA302 and the Tax Year Overview. With the right support, you can get these quickly and keep your application moving smoothly.
