When Should You Get Your Business Accounts Done for a Mortgage Application?

If you're self-employed and planning to buy a home, here's something many business owners don't realise until it's too late: banks need your accounts completed much earlier than the IRD does. Understanding this timing gap can make the difference between getting the loan you need and being stuck waiting months.

The Self-Employed Mortgage Challenge

Self-employed borrowers face distinct challenges compared to salaried employees. While a PAYE worker can provide a few payslips and an employer letter, banks need much more from you: two years of accountant-prepared financial statements (profit and loss, balance sheet), two years of tax returns (IR3), GST returns for the past 12 months, business bank statements for the past 3-6 months, and an accountant's letter confirming income and business viability. The critical point: banks want current year financials, not just historical ones.

The Timing Gap You Need to Understand

Here's where it gets tricky. The IRD's deadline for submitting your 2024/2025 accounts extends to March 2026. Most accountants work to this deadline-which means many self-employed people don't have their current year accounts ready until early the following year.

But banks typically require current-year financials from August onwards. If you're applying for a mortgage in September 2025 and only have 2023/2024 accounts completed, you may find that lenders won't accept the application until current figures are available, your borrowing capacity is calculated on older (possibly lower) income, and competitors with up-to-date accounts get approved faster.

How Banks Calculate Self-Employed Income

Banks don't look at your gross revenue-they look at your net profit (what's left after expenses). This is often much lower than what you "earn."

However, banks may add back certain expenses that don't reduce your actual lifestyle spending, such as depreciation, home office costs, one-off or non-recurring expenses, and personal expenses claimed through the business. This is called "normalised" or "adjusted" profit, and it's what lenders use to calculate your borrowing capacity.

Important: If you've been aggressive with tax deductions to minimise your tax bill, this can backfire when applying for a mortgage. Lower declared profit = lower borrowing capacity.

Strategic Timing for Self-Employed Borrowers

If you're planning to buy property, consider this timeline:

April-May: Get your accounts completed for the financial year just ended. This puts you months ahead of most business owners and gives you current figures when banks want them.

June-July: Arrange your mortgage pre-approval with up-to-date financials.

August onwards: Shop for property with confidence, knowing your borrowing capacity is based on current income.

What If Your Income Is Inconsistent?

Banks typically average your income over two years, which smooths out fluctuations. However, strongly increasing income may be undervalued since banks average rather than use the higher year. Declining income raises red flags, so be prepared to explain why and show projections. And a single bad year can significantly impact your borrowing capacity.

Talk to your accountant about how to present your financials in the best light while remaining accurate and compliant.

Working With Your Accountant

Before applying for a mortgage, have a specific conversation with your accountant. Ask when your accounts will be ready and push for earlier completion if you're planning to buy. Find out your normalised profit, as this is what banks will use. Ask about any add-backs-expenses that could be added back to increase your lending income. And confirm whether they can provide a letter, since banks often want an accountant's confirmation of income.

Some accountants can prepare draft or interim accounts for mortgage purposes if your final accounts aren't ready.

Plan Ahead, Buy Sooner

Proactive financial planning is essential for self-employed borrowers. Don't assume you can apply for a mortgage whenever suits you-coordinate with your accountant to have current financials ready, ideally by April-May each year if you're planning to buy. The earlier your accounts are completed, the stronger your position when you find the right property.
