How Banks View Self-Employed Income

For salaried employees, income is straightforward: payslips, CPF contributions, and the NOA all align. For self-employed individuals, the income figure that matters is taxable income as assessed by IRAS, shown in your Notice of Assessment (NOA). Banks do not use revenue. They do not use bank deposits. They use the number IRAS has assessed as your taxable income after deductions.

This is the source of the most common frustration among self-employed mortgage applicants: a business owner who earns $300,000 in revenue but deducts $180,000 in legitimate business expenses has an IRAS taxable income of $120,000. The bank sees $120,000 × 80% = $96,000 qualifying income. Their mortgage capacity is no different from a salaried employee earning $96,000 per year, despite having three times the revenue.

The 20% Haircut on Variable and Self-Employed Income

MAS Notice 645 (for banks) requires lenders to apply a haircut of at least 30% on variable income. In practice, most banks apply 20 to 30% haircut to self-employed income from NOA. This means only 70 to 80% of the NOA average income is counted. The majority apply 20% (recognise 80%), but confirm with your specific bank or mortgage broker.

Commission earners, real estate agents, insurance agents, financial advisers are treated similarly. Banks take the 2 year average of declared commission income and apply the 20% haircut.

Income Recognition by Employment Type

The Tax Optimisation Dilemma

Self-employed individuals often minimise IRAS taxable income through legitimate business deductions: professional development, equipment, home office, travel, and so on. This reduces the income tax bill, which is sensible tax planning.

However, it creates a direct problem for mortgage qualification: lower taxable income in the NOA = lower qualifying income at the bank. If you are planning a property purchase in the next 12 to 24 months, consider the trade off carefully. Maximising deductions saves you 7 to 22% of the deducted amount in income tax. But reducing your qualifying income by $20,000/year may cost you $70,000 to $100,000 in borrowing capacity.

Required Documents for Self-Employed Mortgage

• 2 years IRAS Notice of Assessment (NOA): AY2024 and AY2025 (for 2026 application)
• 6 months personal bank statements (showing regular deposits consistent with declared income)
• 3 to 6 months CPF contribution history (if self-contributing as voluntary Medisave top ups)
• Business registration documents (for sole proprietors, ACRA bizfile or equivalent)
• Some banks require 2 years of business financial statements for higher loan amounts or company directors

The Joint Application Advantage

The simplest solution for a self-employed borrower with variable TDSR capacity is to apply jointly with a salaried spouse or partner. The salaried income is assessed at face value (0% haircut on fixed component), which anchors the combined TDSR calculation on a stable base. The self-employed income supplements it with the 20% haircut applied.

A self-employed buyer with $96,000 NOA recognised income and a salaried spouse earning $84,000 ($7,000/month) have a combined qualifying income of $180,000, a TDSR allowable monthly debt of $8,250, supporting a loan of approximately $2.3M at 1.5% over 30 years.
