What Documents Are Required for Income Tax Filing in Singapore?

Filing income tax returns in Singapore requires accurate income information and relevant supporting documents. Whether you are a salaried employee, self-employed professional, freelancer, or business owner, maintaining proper tax records helps ensure a smooth filing process.

The documents required may vary depending on your employment status, income sources, and eligibility for tax reliefs. Having the necessary information ready can help reduce filing errors, avoid delays, and ensure that you report your income correctly to the Inland Revenue Authority of Singapore (IRAS).

Here is a checklist of the important documents and information you should prepare before filing your income tax return in Singapore.

1. Personal Identification Details

The first step is to keep your personal identification information ready. These details help IRAS identify you and process your tax return accurately.

You may need:

• NRIC or FIN number.

• Singpass login details for accessing myTax Portal.

• Current residential address.

• Contact details, including email address and phone number.

• Marital status and relevant dependent information, where applicable.

Ensure that your personal details are updated before submitting your tax return.

2. Employment Income Documents

If you are working as a salaried employee in Singapore, you need information about your employment income during the relevant Year of Assessment (YA).

Important documents and information include:

• Annual income statement or employment income details.

• Salary and bonus information.

• Commission and allowances, where taxable.

• Benefits-in-kind provided by your employer.

• Details of income from previous employers, if applicable.

Many employers in Singapore participate in the Auto-Inclusion Scheme (AIS), under which employment income information is submitted directly to IRAS. If your employer participates, you generally do not need to submit the same income information separately, but you should verify the details in your tax return.

3. Documents for Self-Employed Individuals and Freelancers

Self-employed individuals and freelancers must maintain proper records of their business income and expenses.

Depending on your business activities, prepare:

• Sales invoices and receipts.

• Business income records.

• Bank statements related to business transactions.

• Expense receipts and payment records.

• Accounting statements.

• Details of deductible business expenses.

• Records of capital allowances, where applicable.

These documents help determine your net trade income, which is generally calculated after deducting allowable business expenses from business revenue.

4. Rental Income Documents

If you earn rental income from residential or commercial properties in Singapore, you should maintain records of rental payments and related expenses.

Prepare the following information:

• Tenancy agreements.

• Rental income statements.

• Records of rental payments received.

• Property-related expense receipts.

• Property tax statements.

• Records of allowable repairs and maintenance expenses.

These records help you calculate your taxable rental income accurately.

5. Documents for Tax Reliefs and Deductions

Singapore offers various personal tax reliefs to eligible individuals. If you intend to claim tax reliefs, keep the relevant supporting information ready.

Depending on your eligibility, you may need:

• CPF contribution statements.

• SRS contribution statements.

• Approved donation receipts.

• Life insurance premium details, where eligible.

• Course fee and professional development records, where applicable.

• Parent, spouse, or child dependency details.

• Supporting information for eligible parenthood-related reliefs.

Remember that each tax relief has specific eligibility conditions. Check the latest IRAS guidelines before making a claim.

6. Documents for Other Sources of Income

If you receive income from sources other than employment or self-employment, you should also maintain the relevant records.

These may include:

• Dividend statements.

• Interest income statements.

• Overseas income records, where relevant.

• Commission income details.

• Income from additional employment.

• Other taxable income statements.

The tax treatment depends on the nature and source of income, as well as your tax residency status.

7. Previous Tax Returns and Tax Records

Keeping previous tax records can help you maintain consistency when preparing your current income tax return.

You should retain:

• Previous income tax returns.

• Notices of Assessment (NOA).

• Records of previous tax relief claims.

• Supporting documents for deductions.

• Relevant correspondence with IRAS.

For self-employed individuals and businesses, IRAS generally requires relevant accounting records and supporting documents to be retained for at least five years.

Do You Need to Submit All Supporting Documents to IRAS?

No. You generally do not need to submit every supporting document when filing your income tax return in Singapore.

For example, receipts for donations, insurance premiums, course fees, and business expenses are usually not required during filing unless IRAS specifically requests them.

However, you must maintain proper records to support the income, deductions, and reliefs declared in your tax return. IRAS may request these documents for verification.
