Getting a mortgage when you are self-employed

The short answer

Lenders assess self-employed income from tax returns, usually averaging two years and adding back certain non-cash items. Business owners who minimise taxable income aggressively often show far less income than they earn, which is the most common reason a well-paid owner struggles to qualify. Planning two tax years ahead is the real fix.

This is the mortgage problem we get asked about most, because it is the one that affects our actual clients. A business owner doing well, with money in the bank, gets told they do not qualify — and cannot understand why.

To be clear about our role: we do not originate mortgages and a licensed lender will make every decision here. But the mechanism is worth understanding, because the fix takes two years and has to start before you need it.

How lenders see your income

Not from your bank balance and not from your revenue. From your tax returns — typically two years, often averaged, with certain non-cash items added back.

So the question is not what your business earns. It is what your returns say you earn.

Why that hurts business owners

Because good tax planning and mortgage qualification pull in opposite directions.

Aggressive depreciation, a modest owner salary, personal expenses run through the business, and every legitimate deduction taken — all of it reduces taxable income, which is the point. It also reduces the income a mortgage lender can see.

An owner who took home a comfortable living and showed very little on paper has done exactly what their accountant advised and made themselves difficult to lend to. Both things are true.

If you intend to buy a home in the next two or three years, that changes what "optimal" means on your tax return. Have that conversation with your accountant before the returns are filed, not after — because by then the years a lender will examine are already written.

What gets added back

Lenders do adjust. Depreciation and amortisation are non-cash and usually come back. Certain one-off expenses can, with documentation. Depletion and some business use of home items may.

What generally does not come back is a genuinely low owner salary or ongoing personal expenses run through the business. Those are treated as real.

The two-year rule and its exceptions

Most programmes want two years of self-employment history. Some will consider one year where the borrower has a long track record in the same field — moving from employee to contractor in the same trade, for instance.

A borrower who left a salaried job eight months ago to start something new is in the hardest position, and the honest answer is often to wait.

Declining income is the other trap

If year two is lower than year one, many lenders will use the lower figure rather than the average, and will want an explanation. A business that had a bad year and recovered still shows a decline in the window being examined.

Worth knowing if you are choosing when to buy: applying after a strong year is materially easier than applying after a soft one, for the same reasons that apply to business lending.

Practical preparation

  1. Decide roughly when you want to buy, then work backwards two tax years.
  2. Talk to your accountant about the trade-off explicitly, with the purchase in mind.
  3. Separate business and personal finances cleanly. Commingled accounts make everything harder.
  4. Keep your business filings current and consistent. Returns that disagree with financial statements create problems.
  5. Talk to a licensed lender early — a year out, not a month. They can tell you what your returns will actually support, which is the number that matters.

There are also programmes designed for self-employed borrowers that assess income differently. They exist, they are not for everyone, and a licensed lender is the right person to explain whether one fits. That is their job and not ours.

Common questions

Why does my accountant’s advice hurt my mortgage application?
Because minimising taxable income is the right advice for tax and the wrong shape for qualification. Both are legitimate. If a purchase is coming, the accountant needs to know so the trade-off can be made deliberately.
How many years of returns do I need?
Usually two, with some programmes accepting one where there is a strong track record in the same field. Under a year of self-employment is the hardest position and often means waiting.
Does business debt count against me?
It depends on the structure and whether you are personally liable. Business debt with a personal guarantee frequently does count. Worth establishing early, since it affects the ratios directly.
Are there loans for self-employed buyers specifically?
Programmes exist that assess income differently. They are not right for everyone and they carry their own trade-offs. A licensed lender can explain whether one suits you — that is their decision to make, not ours.
