Freelancer Tax Filing Full Process: How to Prove Income Without a Payslip

The Hong Kong Inland Revenue Department (IRD) issued its 2024-25 tax return packs in April 2025, and for the first time, the accompanying notes for individuals explicitly expanded the acceptable evidence for business deductions claimed by self-employed persons. This shift, detailed in the IRD’s “Profits Tax – Guide for Self-Employed Persons” (2025 edition), signals a pragmatic response to the city’s ballooning freelance economy. Official Census and Statistics Department data from 2024 estimates that over 330,000 working-age individuals in Hong Kong now derive their primary income from non-standard employment—freelancers, gig workers, and sole proprietors. For this cohort, the core anxiety of tax filing is not the rate of tax, but the fundamental question of proof. Without a monthly payslip from an employer, how does one substantiate income and, critically, claim the deductions that lower the tax bill? This article provides the procedural framework for a freelancer’s Hong Kong profits tax return, focusing on the documentary evidence the IRD expects, the specific allowances available, and the common pitfalls that trigger an inquiry.

The Legal Basis: Profits Tax for the Self-Employed vs. Salaries Tax

The first distinction a freelancer must internalise is that they are not filing under Salaries Tax (Schedules 8 and 9 of the Inland Revenue Ordinance, Cap. 112). Instead, they are assessable under Profits Tax (Part IV, Cap. 112). This is not a minor administrative detail; it changes the entire structure of the return, the allowable deductions, and the burden of proof.

The Source Rule and the “Trade” Test

For a freelancer to be subject to Hong Kong Profits Tax, the IRD must first establish that the activities constitute a “trade, profession, or business” carried on in Hong Kong. Section 14(1) of the IRO charges profits tax on “every person carrying on a trade, profession or business in Hong Kong.” The IRD’s Departmental Interpretation and Practice Notes (DIPN) No. 21 (Revised) provides the framework for determining whether an activity is a trade or a mere series of isolated transactions. For freelancers, the key indicators are frequency of transactions, the intention to make a profit, and the organisation of the activity. A graphic designer taking on three projects a year for different clients is likely trading; a person selling personal household items on Carousell once a year is not.

Documentary Burden: The Absence of a Payslip

Unlike an employee who receives an IR56B form from an employer, a freelancer must construct their own income record. The IRD expects, at a minimum, a detailed income statement. The acceptable forms of evidence include:

• Invoices issued: Each invoice should carry a unique number, the client’s business name (if applicable), a clear description of the service, the amount in HKD, and the date of issue. The IRD may request a sample of invoices to verify the pattern of business.
• Bank statements: The IRD cross-references the total income declared against deposits into the freelancer’s Hong Kong bank account. A common error is failing to report income received in cash or via third-party payment platforms (e.g., PayPal, Wise). The IRD’s field audit teams, as noted in their 2023-24 Annual Report, now specifically check for discrepancies between declared turnover and bank deposits.
• Contracts or engagement letters: For larger projects (typically over HKD 100,000), a written contract provides the strongest evidence of the business relationship and the source of income.

The “No Payslip” Deduction Strategy

The absence of a payslip is not a disadvantage for deductions. Under Salaries Tax, deductions are tightly capped (e.g., self-education expenses up to HKD 100,000 per year of assessment). Under Profits Tax, a freelancer can claim all expenses “wholly and exclusively” incurred in the production of assessable profits, as per Section 16(1) of the IRO. This is a far more generous regime. Common deductible items for freelancers include:

• Home office expenses: A portion of rent, utilities, and internet, calculated on a floor-area basis. The IRD’s DIPN No. 9 (Revised) provides the “time and space” apportionment method, which is the most defensible.
• Professional subscriptions and continuing education: Unlike the Salaries Tax cap, these are fully deductible if directly related to the trade.
• Equipment and software: The cost of a laptop, camera, design software license, or professional indemnity insurance. Capital expenditure may be eligible for depreciation allowances under Part VI of the IRO.

Filing the Return: The BIR60 and the Supplementary Form

Freelancers do not file a standalone business tax return. They file the standard Individual Tax Return (BIR60) but must complete the supplementary pages for “Sole Proprietorship Business.” This is where most errors occur.

Completing Part 5 of the BIR60

Part 5 of the BIR60 is titled “Profits Tax – Sole Proprietorship.” The taxpayer must enter the net assessable profit (or adjusted loss) from the business. This figure is not the same as the bank account balance. It is the profit computed in accordance with the IRO, after adding back non-deductible items (e.g., private motor car expenses, capital expenditure) and deducting allowable expenses and depreciation allowances.

The Importance of the Tax Computation

The IRD does not require a full set of audited accounts for most small sole proprietorships (turnover below HKD 5 million). However, they do require a tax computation. This is a one-to-two page document that reconciles the accounting profit to the assessable profit. A typical tax computation for a freelancer would show:

• Gross receipts (from invoices)
• Less: Allowable expenses (listed by category)
• Equals: Adjusted net profit
• Less: Depreciation allowances (e.g., 20% reducing balance on a laptop)
• Equals: Assessable profit (the figure entered on the BIR60)

Failing to submit a tax computation with the return, or submitting one that is mathematically inconsistent with the bank statements, is the single most common trigger for an IRD enquiry. The 2024-25 IRD Annual Report noted that over 60% of field audits on small businesses were initiated due to “incomplete or inconsistent supporting documents.”

Deadlines and Penalties

For the 2024-25 year of assessment (ending 31 March 2025), the standard filing deadline for individuals is 2 June 2025 (for paper returns) and 2 July 2025 (for eTAX filers). Freelancers who operate as a sole proprietorship with a business registration certificate are generally given a longer deadline, often November 2025, but this extension is not automatic. The IRD issues a specific “Filing Deadline” notice on the return. Late filing carries a penalty of up to HKD 10,000 and the IRD may also impose a 5% surcharge on the tax assessed.

Proving Income Without a Payslip: The Audit-Proof File

The IRD’s audit cycle for self-employed persons is approximately 4 to 6 years after the filing date, per the statute of limitations in Section 82A of the IRO. A freelancer must maintain records for at least 7 years. The key to surviving an audit is a “paper trail” that is coherent and self-referencing.

The Three-Legged Stool of Evidence

The IRD’s field audit manual (not publicly released but referenced in tax court decisions) looks for three things:

1. Income: Bank statements, invoices, and contracts must agree. If a client pays HKD 50,000 in July 2024, there must be an invoice for HKD 50,000 dated around that time.
2. Expenses: Receipts for deductible items must be detailed. A credit card statement showing a charge at “Apple Store” is not sufficient. The receipt must show the specific item purchased (e.g., “MacBook Pro 16-inch, Serial No. XXXX”).
3. Business purpose: The IRD will challenge expenses that appear personal. A “business meal” at a restaurant on a Sunday evening with no client name noted on the receipt is a red flag.

Handling Client Non-Payment and Bad Debts

A frequent issue for freelancers is the client who does not pay. Under Section 16(1)(d) of the IRO, debts proven to be bad can be deducted. However, the deduction is only allowed in the year the debt is actually determined to be bad, not the year the invoice was issued. The IRD requires evidence of the debt recovery effort: a demand letter, a court judgment, or a final notice from the client’s liquidator. Writing off a debt in the accounts without this evidence will result in the deduction being disallowed on audit.

The Personal Services Company Trap

A freelancer earning over approximately HKD 2 million per year may consider incorporating a “personal services company” to split income and defer tax. The IRD is alert to this structure. DIPN No. 24 (Revised) discusses the “contract of service” vs. “contract for services” distinction. If the IRD determines that the individual is effectively an employee of their own company, they may reclassify the company’s income as the individual’s salary income, subject to Salaries Tax rates and the loss of the Profits Tax deduction regime. The landmark case of Commissioner of Inland Revenue v. Lee Kam Kee (2000) established that the IRD will look at the degree of control, the provision of tools, and the risk of profit/loss to determine the true nature of the relationship.

Practical Filing Strategy for the 2024-25 Year of Assessment

For a freelancer preparing their return in mid-2025, the following sequence is recommended.

Step 1: Reconcile Bank Statements to Invoices

Pull all bank statements from 1 April 2024 to 31 March 2025. Create a spreadsheet listing every deposit from a client. Match each deposit to an invoice. Any unmatched deposit (e.g., a client paying a 2023 invoice in May 2024) must still be reported as income in the 2024-25 year of assessment, as Hong Kong taxes on a receipts basis for most small businesses.

Step 2: Categorise Expenses into Three Buckets

• Direct costs: Materials, subcontractor fees, software licenses. These are fully deductible.
• Operating expenses: Rent, utilities, internet, insurance, professional fees. These are deductible with proper receipts.
• Capital expenditure: Equipment costing over HKD 1,000 and with a useful life of more than one year. These are not directly deductible but qualify for depreciation allowances (Annual Allowance) under Section 34 of the IRO.

Step 3: Prepare the Tax Computation and Review the Allowances

Ensure the tax computation correctly applies the depreciation allowances. For example, a laptop purchased in July 2024 for HKD 15,000 would qualify for an initial allowance of 60% (HKD 9,000) in the first year, plus an annual allowance of 20% on the remaining cost (HKD 1,200), for a total first-year deduction of HKD 10,200. This is a significant benefit compared to an employee who cannot deduct the cost of their work laptop.

Step 4: File via eTAX and Keep the PDF Receipt

The IRD’s eTAX system provides an immediate acknowledgement of filing. Keep this receipt. Also, save a PDF copy of the completed return and the uploaded tax computation. The IRD’s system sometimes fails to render attachments correctly; having a copy of what was submitted is the only way to prove compliance in a later dispute.

Closing: Three Actionable Takeaways

1. Build the three-legged stool: Maintain a consistent record of invoices, bank deposits, and a tax computation; the IRD’s audit focus on self-employed persons starts with a mismatch between these three documents.
2. Claim the home office deduction methodically: Use the floor-area ratio method from DIPN No. 9 (Revised) to deduct a portion of rent and utilities—this is the most defensible approach and is routinely accepted by the IRD on review.
3. File the BIR60 with a complete tax computation, not just a profit figure: The single most common reason for an IRD enquiry into a freelancer’s return is the absence of a supporting tax computation that reconciles the declared profit to the bank statements.
