What are the requirements for 'proof of income' when a bank approves a mortgage?

"Ah Ken, I have all my payroll slips, so why does the bank say my proof of income is insufficient?" A client called me last month with a tone full of helplessness. He had been working as a freelancer for three years, earning a stable 50,000 HKD per month, but when he applied for a mortgage, he discovered that the 'proof of income' in the bank's eyes was completely different from what he understood.

This situation is actually very common. Many prospective buyers think that having a payslip and deposit records is enough, but when it comes time to actually apply for a mortgage, they realize that the bank's requirements for income proof are far more complex than imagined. Especially in Hong Kong's property market, where mortgage loans often amount to several million, banks naturally scrutinize approvals very carefully. Today, we will break down in detail what specific requirements banks have for income proof when approving a mortgage, so that you can be fully prepared before applying and avoid being rejected at the last moment.

Core Concept: 'Proof of Eligible Income' from the Bank's Perspective

Many people think that an income proof is as simple as a payslip, but when a bank approves a mortgage, they will assess your repayment ability from multiple angles. They need to ensure that your income is 'stable,' 'sustainable,' and 'verifiable.'

Salaried Employees: The Most Direct Way to Provide Proof

If you are an employee with a fixed employer and a stable monthly salary, congratulations, your income proof is relatively simple:

Required Documents:

• Payslips for the past 3 months (some banks require 6 months)
• Bank statements for the past 3-6 months (showing salary deposits)
• Copy of employment contract
• Tax documents for the past year (IR56B or tax return)

:::tip Expert Tips The date of deposit on the payroll must match the deposit date on the bank statement. If your company's payroll date is not fixed, or if you pay in cash, the bank will pay special attention and may even require additional supporting documents. :::

Income items calculated by banks:

• Basic monthly salary (calculated at 100%)
• Fixed allowances (such as housing allowance, transportation allowance, usually calculated at 100%)
• Commission/bonus (generally only 50-70% counted, need to provide an average of the past 6-12 months)

Self-employed / Freelancer: Proof Becomes Even More Difficult

If you are self-employed, a freelancer, or running a business, proving your income is much more complicated. Banks will be concerned about the instability of your income, so the requirements will be stricter:

Required Documents:

• Complete tax returns for the past two years (Profits Tax or Personal Income Tax)
• Auditor's reports for the past two years (if applicable to the company)
• Bank statements for the past 6 months (showing business income)
• Copy of business registration certificate
• Certificate of Incorporation of the company (if applicable)

:::warning Common Misconceptions Many freelancers think that paying less tax can save money, but they regret it when applying for a mortgage. Banks calculate your repayment ability based on your declared income, so if you declare less, you can borrow less. Some clients, just to get on the property ladder, even have to amend their taxes for the past two years, but doing so will delay the entire mortgage application process. :::

Bank Calculation Method:

• Usually takes the average taxable profit of the past two years
• Some banks apply a discount (for example, only 70-80%)
• If the business has loss years, it will seriously affect approval

Multiple Income Streams: How to Effectively Combine Them?

Many Hong Kong people have multiple sources of income — in addition to their main job, they also have part-time work, rental income, investment returns, etc. How do banks handle this kind of income?

Countable Additional Income:

1. Rental Income: Lease agreement and rental payment records for the past 6 months are required. Banks generally count only 70% as income (after deducting vacancy periods and maintenance costs).
2. Part-time Income: Payslips, contracts, and payment records are required, usually only 50-70% is counted.
3. Investment Income: Dividends, bond interests, etc., require proof from the past year. Banks calculate this more conservatively.

:::highlight Insider Tip If you have rental income, remember to keep all records of rent received. It's best to use bank transfers and not accept cash, because the bank requires clear proof of deposits. In addition, the lease must be stamped before it will be accepted by the bank. :::

Practical Cases: Analysis of Three Common Situations

After going through the theory, we will use three real cases to see how applicants in different situations should prepare income proof.

Case 1: Fixed Salary but Large Cash Income

Background: Amin is a sales manager at a small to medium-sized enterprise, with a monthly salary of 30,000, but he also earns 20,000–30,000 in commission each month, which the company pays in cash. When he applies for a mortgage, the bank only considers his basic monthly salary and does not count the cash commission.

Problems:

• Cash income cannot be verified
• Commission items are not shown on the food orders
• Bank statements have no corresponding deposit record

Solution:

1. Request the company to change the commission to a bank transfer and keep records for at least 6 months.
2. Update the payslip to clearly state the commission items.
3. Provide proof of commission income for the past year (such as a company letter).

Result: After 6 months of preparation, Amin successfully included commissions in his income calculation, increasing his mortgage loan amount by 40% and smoothly purchasing a property.

Case 2: Freelancer's Income Fluctuates Greatly

Background: Janice is a freelance designer, earning between 20,000 to 80,000 per month. To save on taxes when filing, she only reported 60% of her actual income. When applying for a mortgage, the bank calculated based on her reported income, resulting in a serious shortfall in repayment ability.

Problems:

• Tax-declared income is too low
• Monthly income fluctuates greatly, making it difficult for banks to assess stability
• Some income lacks official invoices

Solution:

1. Submit back taxes for the past two years (takes 3-6 months)
2. Organize all client contracts and invoices
3. Provide bank statements for the past 12 months to prove actual income
4. Consider finding a guarantor (such as parents) to increase approval chances

Result: After Janice eventually filed her tax return, she successfully got mortgage approval, but the process took 8 months, causing her to miss out on her desired bargain property.

:::success Key to Success When a freelancer applies for a mortgage, the most important thing is to plan early. If you plan to buy a property within two years, you need to seriously report your taxes now and keep all proof of income. The tax savings in the short term are far less than the mortgage loan amount lost in the long term. :::

Case 3: Investors with Rental Income

Background: David has a full-time job with a monthly income of 40,000. Additionally, he owns two rental units, earning a total of 30,000 per month in rental income. He wants to buy a third unit for self-occupation and hopes to include the rental income when applying for a mortgage.

Issues:

• One of the leases was not stamped
• The tenant pays rent in cash, with no bank record
• The bank is only willing to calculate 70% of the rental income

Solutions:

1. Immediately have the lease stamped (takes 1 month)
2. Request the tenant to pay rent via bank transfer
3. Provide rent deposit records for the past 6 months
4. Prepare a property valuation report to prove the rent is reasonable

Result: David successfully included rental income in the calculation, but the bank only counted 70% (i.e., 21,000), and he was eventually approved for a mortgage, successfully purchasing a third unit.

Notes: Five Common Mistakes and Pitfall Avoidance Guide

When applying for a mortgage, many people stumble over income proof requirements. Here are the five most common mistakes—see if you fall into any of them.

Misconception One: Thinking that simply having a ration card is enough

Many people think that having a pay slip is enough to apply for a mortgage, but in fact, banks also need to verify your bank statements. If the amount on the pay slip does not match the deposits in the bank, the bank will question the authenticity of your income.

Pitfall Avoidance Guide:

• Ensure the payroll list matches the bank deposit date and amount
• If the company delays salary payment, prepare a letter from the company explaining
• Avoid paying salaries in cash, switch to bank transfer

Misconception 2: Preparing documents at the last minute

Many people only start preparing income proof when signing a provisional agreement, and end up discovering that the documents are incomplete, resulting in a delay in the transaction or even losing the deposit.

Pitfall Avoidance Guide:

• Prepare all documents before viewing a property
• Regularly update payslips and bank statements
• If self-employed, start organizing tax documents a year in advance

Misconception Three: Hiding Debts or Other Mortgages

Some people think that if they don't mention the bank, it won't find out, but actually the bank will check your credit report (TU), and all loans, credit card debts, and other mortgages will be clearly recorded.

Pitfall Avoidance Guide:

• Proactively declare all debts
• Try to pay off credit card balances before applying for a mortgage
• If you have other mortgages, prepare proof of payments

:::warning Serious consequences If the bank discovers that you have concealed debts, not only will it refuse your mortgage application, but it may also blacklist you, affecting all future loan applications. :::

Misconception 4: Thinking that paying less tax can save money

This is a common problem among many self-employed individuals and freelancers. In the short term, they save a bit on taxes, but when applying for a mortgage, they realize they cannot borrow enough, ultimately having to amend their tax returns, which delays the entire home-buying plan.

Pitfall Avoidance Guide:

• If you plan to buy a property within two years, file taxes carefully
• Tax-reported income should reflect actual income
• Consult an accountant to balance tax requirements and mortgage needs

Misconception Five: Ignoring Stress Test Requirements

Even if you have all your income proof, the bank will still do a stress test to ensure that you can still afford the payments if interest rates rise by 3%. Many people only calculate based on the current interest rate and ignore the stress test, resulting in not being approved for the full mortgage amount.

Pitfall Avoidance Guide:

• Use a mortgage calculator, including the stress test
• Reserve enough down payment to reduce the mortgage ratio
• If you fail the stress test, consider finding a guarantor

:::tip Pressure Test Formula Monthly payment ÷ monthly income ≤ 50% (current interest rate) Monthly installment (interest rate +3%) ÷ monthly income ≤ 60% (stress test) :::

Professional Advice: How to Improve Mortgage Approval Success Rate

After looking at so many cases and pitfalls, you might ask: "So what should I do to increase the chances of mortgage approval?" Here is my professional advice.

Plan Ahead, Allow Plenty of Time

Don't wait until you are looking at your preferred unit to start preparing. Ideally, start organizing income proof 6-12 months in advance, especially for self-employed individuals and applicants with multiple sources of income.

Action List:

• Regularly update the food supply list and bank statements
• Organize all lease and contract documents
• Ensure tax records are complete
• Repay unnecessary debts

Choosing the Right Bank

Different banks have different requirements and calculation methods for income proof. Some banks are more lenient towards self-employed individuals, while others are more aggressive in calculating commission income.

Strategy Recommendations:

• Apply to 2-3 banks at the same time and compare the terms
• Get help from a mortgage broker, they are familiar with the requirements of each bank
• If one bank rejects, don't be discouraged, try other banks

Maintain a Good Credit Record

When a bank approves a mortgage, besides looking at income proof, they will also check your credit rating (TU). A good credit record can greatly increase the chances of approval.

Ways to Maintain a Good TU:

• Make repayments on time (credit cards, loans)
• Avoid applying for multiple credit cards at the same time
• Keep credit card balances below 30% of the credit limit
• Regularly check your own credit report

Consider Getting a Guarantor

If your income proof may not be stable enough, or you might fail the stress test threshold, you can consider finding a guarantor (usually a parent or spouse). The guarantor's income will be calculated together, greatly increasing the chance of approval.

Guarantor Notes:

• The guarantor needs to provide complete proof of income
• The guarantor's debts will also be taken into account
• The guarantor needs to understand their legal responsibilities

Summary: Be Well Prepared, Get On Board Smoothly

Applying for a mortgage is not an easy task, especially when it comes to income verification. Banks have strict requirements and the documents are complicated. But as long as you plan ahead and prepare everything thoroughly, it's actually not difficult to handle.

Remember the following key points:

1. Salaried Employees: Prepare payslips, bank statements, and tax documents, ensuring all documents are consistent.
2. Self-Employed Individuals: File taxes properly, keep all proof of business income, and start preparing 6-12 months in advance.
3. Multiple Income Sources: Organize all leases and contracts, ensuring clear records of income.
4. Avoid Common Mistakes: Do not hide liabilities, do not wait until the last minute, and do not underreport income to save on taxes.
5. Increase Approval Chances: Maintain a good credit record, choose the right bank, and consider having a guarantor.
