Tax Returns vs Notices of Assessment: What’s the Difference?

Tax Returns vs Notices of Assessment: What’s the Difference and Why Lenders Ask for Both

When applying for a home loan or refinance, you’ll often be asked to provide financial documents such as tax returns and Notices of Assessment (NOAs). While both documents are closely related, they serve very different purposes, understanding the difference can help to make your loan application smoother and faster.

At first glance, many borrowers assume these documents are interchangeable but they’re not. Let’s break down what each one is, why lenders need them, and why both are so important in the lending process.

What Is a Tax Return?

Your tax return is the document you (or your accountant) lodges with the Australian Taxation Office (ATO) each financial year. It details a breakdown of your income, deductions, expenses, and other financial information for that year.

For lenders, tax returns are primarily used to:

• Assess income stability and consistency

• Understand how your income is generated

• Review deductions and expenses

• Verify income for self‑employed borrowers, contractors, and investors

What lenders look for in a tax return?

If you’re self‑employed or earn an income outside of PAYG employment, lenders usually want:

• The last two financial years of personal tax returns

• Business tax returns, if applicable

• Confirmation of income trends (increasing, stable, or declining)

Tax returns tell the story of your income, but your tax return doesn’t confirm that the ATO has accepted it.

What Is a Notice of Assessment (NOA)?

A Notice of Assessment is issued by the ATO after your tax return has been assessed. It confirms:

• The income the ATO has accepted

• The tax payable or refund due

• Any outstanding tax debts

In short, your NOA is the ATO’s official confirmation that your tax return is finalised and all figures are correct.

Why lenders rely on NOAs?

From a lender’s perspective, an NOA provides:

• Independent verification from the ATO of income

• Assurance that the tax return has been lodged and accepted

• Confirmation that there are no unresolved tax issues

• Confidence that financial figures aren’t provisional or speculative

Think of the tax return as a draft, and the NOA as the official stamp of approval.

Why Lenders Often Require Both

Lenders assess risk very carefully, especially when income is not straightforward. Each document plays a different role:

Tax Return: Shows how income is earned and structured

Notice of Assessment: Confirms the income declared has been verified by the ATO

A tax return without an NOA is considered unverified. An NOA without the tax return lacks detail about how income is generated. Together, they give lenders the full picture.

Common Misunderstandings and Questions

“My tax return is lodged - surely that’s enough?”
Not always. Until the ATO issues a NOA, the figures aren’t validated.

“I can’t get my NOA yet - does that mean I can’t apply?”
Not necessarily. Some lenders will allow applications using accountant‑prepared figures or lodged‑but‑not‑assessed returns, but this may limit your borrowing options.

“My NOA shows less income than I expected.”
This can happen if deductions reduce taxable income. Lenders often assess income differently than the ATO, which is where broker guidance can be invaluable.

How a Mortgage Broker Helps?

Understanding how lenders interpret tax returns and NOAs can be complicated -especially if you’re self‑employed. A mortgage broker can:

• Review your documents before submission

• Identify lenders best suited to your income structure

• Help explain legitimate deductions that won’t hurt borrowing capacity

• Advise whether you need to wait for an NOA or can proceed sooner

In Summary

Both tax returns and Notices of Assessments play a crucial role in the lending process. One explains how you earn money; the other confirms that the income has been officially accepted. Providing both upfront can save time, reduce questions from the lender, improve your chances of approval or speed up the application process.

If you’re unsure what documents you’ll need, or how your income will be assessed, speaking with an experienced mortgage broker early can make all the difference.
