What is foreign income shading on an Australian home loan?

Foreign income shading is a discount applied by Australian lenders to overseas salary income when calculating borrowing capacity. After converting your income to AUD, lenders typically only count 70–80% of the resulting figure to account for currency fluctuation risk.

How much does foreign income shading reduce my borrowing capacity?

The combined effect of currency conversion, income shading, and tax rate application can reduce your assessed borrowing capacity by 30–40% compared to an equivalent AUD income. The exact amount depends on the lender, your currency, and your income structure.

Do all Australian lenders shade foreign income the same way?

No. Shading percentages and tax rate policies vary significantly by lender. Some apply 20% shading; others apply 30% or more. Some use local tax rates (e.g. Singapore's); others apply Australian marginal rates to overseas income. This is why the choice of lender matters enormously for expat borrowers.

Does bonus or RSU income count for an Australian expat home loan?

Bonus income is typically included if it's been paid consistently for two or more years, evidenced by payslips. RSU treatment varies by lender — some include vesting values; others exclude them. Allowances (housing, car) are also lender-specific. A specialist broker can identify which lenders treat your income structure most favourably.

Foreign Income Shading: How Australian Lenders Assess Your Overseas Salary

TL;DR: When you apply for an Australian mortgage using overseas income, lenders don't assess your full salary. They convert it to AUD at a discounted exchange rate, then shade (discount) the resulting figure by 10–30% to account for currency risk. The exact shading depends on the lender and currency. This directly determines how much you can borrow — and choosing the wrong lender can cost you hundreds of thousands in borrowing capacity.

This is the thing that trips up most expat mortgage applications. Not the distance. Not the paperwork. It's this.

Australian lenders were built to assess Australian dollar salaries. When your income is in SGD, HKD, AED, or any other foreign currency, they have to convert it — and they don't do it at the rate your FX app shows you.

What Foreign Income Shading Actually Means

Shading is a discount applied to your income before it's used to calculate borrowing capacity. Most lenders only count 70–80% of your converted foreign salary for serviceability purposes. Some go as low as 60%.

Here's what that looks like in practice.

Say you earn $15,000 SGD per month. At spot rate, that's roughly $16,500 AUD. A lender using 80% shading would assess you on $13,200 AUD/month. A lender using 70% shading would assess you on $11,550 AUD/month. That $1,650 difference in assessed monthly income changes your maximum loan by roughly $270,000–$350,000 depending on the loan term and current rates.

That's not a rounding error. That's the difference between being able to buy a property in your target suburb or not.

Why Lenders Shade Foreign Income

The logic is straightforward even if the impact is frustrating. Your mortgage repayments are fixed in Australian dollars. Your income is not. If the SGD weakens against AUD by 15%, your effective Australian dollar income just dropped by 15% — but your loan repayment hasn't changed.

Lenders build in a buffer for this. APRA (the prudential regulator) doesn't specify an exact shading percentage — it just requires "sound credit risk management" — so lenders set their own policies. This is why the shading varies so much from lender to lender.

The Tax Rate Problem Most Brokers Miss

Shading is one issue. The tax rate applied to your income is another — and this one's less obvious.

Some Australian lenders assess your overseas income using Australian tax rates. Not Singaporean. Not Hong Kong rates. Australian rates, which top out at 47%.

Singapore's effective tax rate for a high-earning expat is typically 15–22%. Hong Kong's is capped at 17%. If a lender applies Australian marginal rates to your SGD salary, your assessed net income drops significantly — even before the currency shading kicks in.

The right lenders apply local tax rates to local income. Finding those lenders is the entire point of using a specialist broker. It's not about schmoozing a bank manager — it's about knowing which lenders will treat your income correctly before you submit anything.

Which Currencies Get Better Treatment

USD, GBP, EUR, SGD, and HKD are all generally accepted by major lenders. AED is accepted by most specialist expat lenders. Less common currencies require a specialist lender review.

Within accepted currencies, treatment varies. SGD and HKD — the two most common for AEXPHL's clients — are well-understood by specialist lenders. Some lenders have dedicated policies for Singapore and Hong Kong-based borrowers. Others lump all foreign income together and apply blanket shading.

How This Affects Your Borrowing Capacity

The compounding effect of currency conversion, shading, and tax rate application can reduce your assessed borrowing capacity by 30–40% compared to what you'd have if your income were in AUD.

That sounds stark. The good news is that specialist expat lenders exist specifically to avoid this. They apply local tax rates, use more generous shading, and have existing frameworks for assessing the income structures common to expats in Singapore, HK, and Dubai — base salary, bonuses, RSUs, housing allowances, and more.

Bonus and RSU Income

Base salary is the straightforward part. It gets more interesting with bonus structures and RSUs.

Most lenders will include bonus income if it's demonstrably recurring — typically two years of payslips showing bonus payments. One-off bonuses generally don't count.

RSUs (restricted stock units) are more lender-specific. Some count the vesting value. Others exclude them entirely. If a significant portion of your income is in RSUs, this matters a lot for which lender you approach.

The same applies to housing and car allowances — which are common in Singapore and HK packages. Some lenders count them as income. Others strip them out. The difference can be material.

What to Do About It

The short version: don't go to a generalist broker or apply directly to a major bank without understanding how they'll assess your income. You may get a lower offer than you should — or a rejection that wasn't warranted.

The longer version: work with a broker who knows which lenders apply local tax rates to your specific currency, which accept your income structure (base + bonus + RSUs + allowances), and which will give you the most accurate picture of what you can actually borrow.

That's the work we do. If you'd like to run through your numbers, we can map your income against the current lender landscape and give you a realistic borrowing range — before you start looking at properties.
