Most mortgage guides assume you have a payslip. If you're a founder, freelancer, or consultant, the process looks very different — and the common advice often doesn't apply to you.
This is the guide we wish existed.
What documents you'll need
Forget the standard "3 months payslip" checklist. For non-standard income, banks want:
For sole proprietors and self-employed:
- Last 2 years' Notice of Assessment (NOA) from IRAS
- Last 2 years' business financial statements (if applicable)
- Business registration (ACRA)
- Bank statements showing business income (6–12 months, depending on bank)
For company directors:
- Last 2 years' NOA (personal)
- Company's latest 2 years of audited accounts
- Board resolution confirming your role and compensation
- Payslips if you take a formal salary from the company
For commission earners:
- Last 2 years' employment letter confirming commission structure
- 12 months of commission payslips or income statements
- Latest NOA
Banks want to see consistency. Erratic income — even high income — is a yellow flag. Two years of stable or growing documented income matters more than any single month figure.
How banks assess self-employed income
Banks don't just take your word for it. They triangulate.
For sole proprietors, the standard approach is:
- Take your NOA for the last 2 years
- Average the declared trade income
- Apply a 30% MAS haircut
- Use that number as your monthly gross income for TDSR
Example: NOA shows $180,000 trade income in 2024, $156,000 in 2023. Average: $168,000/year → $14,000/month After 30% haircut: $9,800/month assessed income
This is why sole proprietors often find their loan eligibility surprisingly low despite strong actual earnings.
The problem with aggressive tax minimisation
If you've been declaring minimal taxable income to reduce your tax bill — a common and perfectly legal strategy — you've also been minimising your bankable income.
There's no easy workaround here. The bank relies primarily on IRAS-verified figures. Some banks will consider bank statements showing higher inflows, but they'll also want to understand the discrepancy, and they may still anchor to NOA figures.
The uncomfortable truth: optimising for low taxes now can cost you significantly in loan eligibility later. It's worth modelling this tradeoff early if you plan to buy property.
Which banks are more flexible?
Not all banks apply the rules the same way. Within MAS guidelines, banks have discretion on:
- Dividend treatment: Some banks apply 0% to dividends (conservative), others apply the standard 70%. Worth asking explicitly.
- Commission income: Some banks accept 12 months of documented commissions; others want 24.
- Foreign income: Standard 30% haircut applies everywhere, but documentation requirements vary.
- Asset pledge: All major banks accept this, but eligible asset types differ.
The most consistent general advice: work with a mortgage broker who specifically handles self-employed clients. They know which banks have more flexible underwriting for your profile.
What to prepare before applying
Three to six months before applying:
- Ensure your NOA is filed and available (don't apply mid-year before your latest NOA is out)
- Get your business financials in order if banks will ask for them
- Don't make large unexplained transfers in/out of your accounts
- Check your credit bureau report (you can request this from Credit Bureau Singapore)
At application:
- Prepare a clear income narrative — why your income looks the way it does, especially if it's variable
- Consider applying to 2 banks simultaneously; different underwriters may assess the same income differently
- Don't take on new debt obligations in the 3 months before applying (it directly affects TDSR)
A note on IPA (In-Principle Approval)
Get an IPA before you make an offer on a property. It's a preliminary loan approval based on your financial profile, and it tells you:
- Roughly how much you can borrow
- Any documentation gaps the bank wants addressed
- Whether your income profile raises any flags
An IPA costs nothing and expires after 30–90 days depending on the bank. If you're house-hunting, it's essential.
Run the TDSR Calculator to model your specific income mix before your first bank conversation.
