Where to Find Your Tax Year Overview in HMRC

A lender asks for a Tax Year Overview, your mortgage application is moving, and HMRC’s online account suddenly feels less straightforward than it should. If you are wondering where to find your tax year overview, the good news is that it is normally available through your Self Assessment account - provided your return has been submitted and processed.

For sole traders, CIS subcontractors, landlords and company directors with Self Assessment responsibilities, this document is often needed alongside an SA302. It gives a clear record of the tax calculation for a particular year and the payments HMRC has recorded against it. That makes it useful evidence of income and tax paid, but it is not the same thing as your tax return, your SA302, or a bank statement.

Where to find your tax year overview online

The Tax Year Overview is accessed through your HMRC online services account using your Government Gateway sign-in details. Once you are signed in, go to the Self Assessment area rather than the PAYE or Personal Tax Account sections.

From there, select More Self Assessment details. You should then see an option for Tax year overview. Choose the tax year you need, and HMRC will show the calculation and payment position for that period. You can print the page or save it as a PDF if you need to send it to a mortgage broker, lender, letting agent or other third party.

The usual route is:

1. Sign in to your HMRC online services account.

2. Open the Self Assessment section.

3. Choose More Self Assessment details.

4. Select Tax year overview.

5. Pick the required tax year and print or save the page.

Tax years run from 6 April to 5 April, not from January to December. So, for example, the 2024/25 tax year covers income earned between 6 April 2024 and 5 April 2025. This catches people out regularly when they are asked for the “latest year” and select the wrong one.

What your Tax Year Overview actually shows

Your overview confirms the Self Assessment tax calculation for the selected year and records the payments and credits held by HMRC. Depending on your circumstances, it may include Income Tax, Class 2 National Insurance, Class 4 National Insurance and any interest or penalties attached to the account.

This is why lenders frequently ask for it. An SA302 shows the income declared and the tax calculation. The Tax Year Overview helps confirm that the tax position has been recorded by HMRC and indicates whether the amount due has been paid.

If you are self-employed, this distinction matters. A strong year’s turnover on a tax return is useful evidence, but a lender may still want to see that the corresponding tax records are up to date. For landlords, the same principle applies: rental income on an SA302 may need to be supported by the Tax Year Overview for the relevant tax year.

Why your overview may not look as expected

The figure shown is based on HMRC’s records at that point in time. It can therefore look different from the amount you first expected to pay when you submitted your return.

One common reason is payments on account. If you are a sole trader or landlord and your tax bill is more than £1,000, HMRC may ask for advance payments towards the following year’s tax. These are not an extra tax charge in themselves, but they can make the total payment requested in January look much higher than the tax due for the completed year.

CIS subcontractors can also see differences where tax deductions have been reported late, entered incorrectly, or not yet matched properly to their Self Assessment record. Keep hold of your CIS deduction statements throughout the year. They are the evidence needed to support the tax deducted from your payments, particularly where a refund is due.

For limited company directors, the position can be more varied. The Tax Year Overview only relates to your personal Self Assessment account. It does not replace your company’s Corporation Tax records, statutory accounts, VAT returns or payroll reporting. Dividends, salary, rental income and other personal income may all appear in your Self Assessment calculation, but the company’s taxes are dealt with separately.

When will a Tax Year Overview be available?

You will usually need to submit your Self Assessment return before the overview is available for that year. HMRC must also have processed the return, so it may not appear immediately after submission.

If you have just filed online and a lender is waiting, allow time for HMRC’s account to update. Do not assume that a submission confirmation is the same as a processed return or that it will satisfy a lender’s request. Requirements differ between lenders, and some will specify exactly which years they need and whether they want the overview and SA302 together.

In most cases, lenders ask for two or three years of documents. Check the wording carefully before downloading anything. Sending 2023/24 when they have requested 2022/23 and 2023/24 can create an unnecessary delay, especially if you are trying to secure a mortgage offer or remortgage before a deadline.

If you cannot see the Tax Year Overview option

First, make sure you are signed into the correct Government Gateway account. Many business owners have more than one login, particularly if they have a VAT account, PAYE scheme and personal Self Assessment account. The Tax Year Overview sits within the personal Self Assessment service.

Next, check whether your Self Assessment return for the requested year has actually been filed. If it has not, there will be no completed calculation for HMRC to show. If it was filed very recently, give HMRC time to process it before trying again.

A missing overview can also point to an account access issue. Your Self Assessment service may not be connected to the Government Gateway credentials you are using, or you may have changed address, contact details or security settings. In those cases, do not keep guessing at passwords and lock yourself out. Recover access through HMRC’s sign-in process and make sure your Unique Taxpayer Reference is linked to the right account.

If the page is visible but the payment figures do not make sense, compare them with your payment confirmations and tax return calculation. It may be a timing issue, a payment allocated to another year, or a record that needs correcting. This is particularly worth checking before you provide documents to a lender, because an unexplained balance can prompt further questions.

Tax Year Overview versus SA302: what should you provide?

An SA302 and a Tax Year Overview are often requested as a pair, but they serve different purposes. The SA302 is the tax calculation generated from your Self Assessment return. It sets out declared income, allowances, tax due and National Insurance for the year.

The Tax Year Overview is the companion document that shows the position on HMRC’s account. A lender may use both to assess income and see whether your tax affairs are current. If their request simply says “proof of income”, ask your broker or lender whether both are required rather than sending incomplete paperwork and waiting for it to be rejected.

Be careful not to confuse either document with HMRC’s Annual Tax Summary. That summary is generally aimed at PAYE taxpayers and explains how Income Tax has been spent. It is not normally the document requested for a self-employed mortgage application.

Keep your records ready, not just your return

The easiest time to deal with a Tax Year Overview request is before someone urgently asks for one. Once your Self Assessment return is filed, save copies of the submitted return, SA302 and Tax Year Overview in a secure folder, labelled by tax year. Keep your CIS statements, rental records, bank interest certificates and business expense evidence with your wider records too.

That habit is useful beyond mortgages. It gives you a cleaner audit trail if HMRC raises a query, helps when planning cash flow for payments on account, and makes it easier to show an accountant the full picture without digging through old emails and paperwork.

Where figures are unclear, it is better to resolve the issue early than explain it under pressure. Short And Sons Accountants can help self-employed workers, CIS subcontractors, landlords and directors check their Self Assessment position, correct errors and keep the records needed when an opportunity or deadline arrives.
