When Does a New Company File Its First Profits Tax Return?
Many new business owners assume they need to file a Hong Kong tax return “immediately after incorporation” — this is actually incorrect. The IRD does not issue a Profits Tax return in the company’s first year of incorporation; instead, it generally proactively issues the first Profits Tax return about 18 months after incorporation, i.e. Form BIR51 (for limited companies) or BIR52 (for partnerships) (IRD: Types of Hong Kong Company Tax Returns).
This 18-month period doesn’t mean you can ignore tax matters entirely during that time — it simply refers to when the IRD proactively mails the return. During this period, your company still needs to maintain complete accounting records, receipts, and bank records, because once the first Profits Tax return is issued, you typically only have 1 month to submit it (unless an extension is obtained through a tax representative).
One thing to note in particular: first-year filing is not “file first, audit later”. Hong Kong company law and the Inland Revenue Ordinance require the Profits Tax return to be submitted together with an audited financial statement issued by a practising accountant — you cannot submit the return first and supplement the audit report afterwards. In other words, you need to have your complete accounts ready for the auditor to issue a report before and after the first Profits Tax return is issued, in order to file.
If you fail to submit the return by the deadline, the IRD has the right to issue an “estimated assessment”, and may charge you provisional tax or penalties before your actual accounts have been finalised. This often catches first-time business owners off guard — they assumed they could handle the audit gradually, only to receive a tax bill far higher than their actual profits.
A practical example: suppose your company was incorporated on 1 June 2026 with a financial year-end of 31 March — your first Profits Tax return would be issued at the earliest around April 2028. That means nearly two years pass between incorporation and receiving the first Profits Tax return — but your accounts and receipts for those two years must be complete and ready, because once the return arrives, the audit report and tax computation must follow right behind it.
How Is Profits Tax Calculated? Two-Tiered Rates and a Tax-Saving Example
Hong Kong Profits Tax operates under a two-tiered rate system, in effect since the 2018/19 tax year and unchanged for the 2025/26 and 2026/27 tax years (IRD: Profits Tax Rates):
| Assessable Profits | Limited Company Rate | Unincorporated Business (Sole Proprietorship/Partnership) Rate |
|---|
| First $2,000,000 | 8.25% | 7.5% |
| Excess over $2,000,000 | 16.5% | 15% |
Note a key restriction: within the same group, only one entity may elect to enjoy the two-tiered rates — all other connected companies are taxed in full at the standard rate (16.5% or 15%). When filing, the IRD requires disclosure of whether any connected entity also enjoys the two-tiered rates, to prevent groups from splitting into multiple companies to repeatedly dilute the tax bands.
Tax-Saving Example (Illustrative Calculation Only, Not Individual Tax Advice)
Suppose a limited company has assessable profits of exactly $2,000,000 for the year — comparing the “two-tiered” scenario with a hypothetical “all taxed at 16.5%” scenario:
| Item | Actual Tax Under Two-Tiered System | Hypothetical Without Two-Tiered System (All at 16.5%) |
|---|
| First $2,000,000 × 8.25% | $165,000 | — |
| $2,000,000 × 16.5% (hypothetical) | — | $330,000 |
| Tax Payable | $165,000 | $330,000 |
| Tax Saved | — | $165,000 |
In other words, at assessable profits of exactly $2,000,000, the two-tiered system saves the company $165,000 in actual tax — effectively cutting the tax bill in half. For profits above $2,000,000, the tax-saving effect of the two-tiered system gradually dilutes (since the excess is still taxed at 16.5%), but the tax saved on the first $2,000,000 remains a fixed $165,000, applicable to any limited company with profits at or above $2,000,000.
This is purely an illustrative calculation of how the two-tiered system works — actual tax payable still depends on factors such as whether the company has other connected entities also enjoying the two-tiered rates, and any tax computation adjustments (such as non-deductible expenses or capital allowances). We recommend having a practising accountant verify the actual figures when filing.
It’s also worth noting that under the 2026/27 Budget, the IRD is offering a one-off 100% reduction in Profits Tax for the 2025/26 tax year, capped at $3,000 per case (IRD: Profits Tax Rates) — this reduction is applied automatically upon assessment, with no separate application needed.
What Documents Do You Need to Prepare for Company Tax Filing?
For a limited company filing Profits Tax, you essentially need to prepare three core documents:
- Audited Financial Statements — issued by a practising accountant (CPA) in accordance with Hong Kong Financial Reporting Standards, including the profit and loss statement, balance sheet, and notes.
- Profits Tax Return (BIR51, for limited companies) — filed together with supplementary forms.
- Tax Computation — adjusts accounting profit to assessable profit, e.g. adding back non-deductible expenses (fines, private expenses) and deducting capital allowances.
The cost of these documents varies depending on the company’s transaction volume and total revenue. Using Alpha’s fees as an example: bookkeeping fees are based on the number of bank transactions, starting from $3,500 for up to 500 transactions; audit fees are tiered by the company’s total revenue, with a fee of $7,000 for total revenue under $2 million. Combined, this gives you the approximate annual accounting and audit cost for a small trading or service company. Higher revenue and more transactions increase the fee accordingly.
Can Offshore Income Be Exempt From Profits Tax? How to Apply
Hong Kong operates under the territorial source principle — only profits sourced in Hong Kong are subject to Profits Tax, while profits sourced outside Hong Kong are, in principle, not taxable (IRD: Scope of Charge to Profits Tax). The IRD primarily refers to Departmental Interpretation and Practice Notes No. 21 (DIPN 21) when determining the source of profits, with the core concept being the “operations test” — where the profit-generating operations actually took place — rather than the company’s place of incorporation or the location of its bank account.
However, it must be said honestly: an offshore exemption application carries a very heavy burden of proof, and IRD scrutiny has become increasingly strict in recent years. Vague statements such as “our customers are overseas” or “the company has no Hong Kong office” are far from sufficient to obtain an exemption. In practice, the IRD will require submission of:
- Sale and purchase contracts and related correspondence (showing where negotiation and signing took place)
- Invoices and payment records
- Proof of employees’ work locations and functions (who is responsible for procurement, who for sales decisions)
- A description of the company’s actual operational process (whether goods pass through Hong Kong, whether there is Hong Kong warehousing or office space)
The IRD reviews each transaction individually and may request additional documents or arrange an interview. If the evidence is insufficient, the IRD has the right to reject the offshore claim entirely and assess back tax and interest. Precisely because this type of application involves substantial document preparation and correspondence, Alpha’s fee for a full offshore exemption response service is $20,000 per letter, reflecting the actual workload involved — it is not a simple procedure that “gets approved with minimal documents.”
In short: offshore exemption is a genuine mechanism under Hong Kong’s tax system, but it is not “automatic tax exemption” and should not be treated as a routine tax-saving technique. We recommend first assessing whether your business model genuinely meets the substantive requirement that “profits are not generated in Hong Kong” before deciding whether it’s worth investing the resources to apply.
What Happens if You Don't File or File Late?
If you receive a Profits Tax return and fail to submit it on time, or don’t file at all, the consequences are more serious than you might think:
- The IRD can directly issue an “estimated assessment”, often for an amount higher than your actual profits, requiring you to pay a potentially excessive amount of tax upfront before resolving it through the objection process.
- A first-time late filing generally incurs a penalty of around 10% of the tax (if the return is filed only after two or more estimated assessments have been issued, the penalty can rise to 20%); a second offence within 5 years can reach 20% (or 30%), and a third or subsequent offence can reach 35% (or 50%) (IRD: Penalty Policy).
- Persistent non-compliance, deliberate tax evasion, or making false statements can lead to criminal prosecution under the Inland Revenue Ordinance, with a maximum penalty of $50,000 plus 3 times the amount of tax evaded and up to 3 years’ imprisonment — directors bear personal legal liability (IRD: Penalty Policy).
If you’ve already received an IRD enquiry letter but your company’s records are somewhat disorganised, many business owners choose to have an accountant prepare the response on their behalf to ensure it’s complete and accurate. Using Alpha’s fees as a reference: a general document-list enquiry response service is $3,000, while more complex technical enquiries (e.g. involving disputes over the scope of charge or cost recognition principles) are $8,000.
What Is Provisional Tax? Why Do You Pay Two Years' Tax in the First Year?
Many business owners are shocked the first time they receive a Profits Tax bill, because the first-year assessment usually isn’t just one year’s tax — it’s “this year’s tax” + “next year’s provisional tax” combined, making the amount appear to “double.”
This is part of how Hong Kong’s tax system is designed: because Profits Tax is charged on actual profits, but the IRD needs to ensure next year’s tax can be collected, it assesses your current year’s tax while also using this year’s assessable profits as an estimate to pre-collect next year’s provisional tax. Once the actual Profits Tax return for the following year is filed and real profits are calculated, the provisional tax already paid is used to offset the actual tax for that year, with any excess refunded or shortfall billed.
If you have reasonable grounds to believe next year’s profits will be significantly lower than this year’s (e.g. loss of customers, business transformation, worsening economic conditions), you can apply to the IRD for a holdover of provisional tax, with common grounds including an expectation that assessable profits will be less than 90% of the previous year’s. The application must be submitted 28 days before the provisional tax payment deadline, or within 14 days of the provisional tax notice being issued (whichever is later).
Frequently Asked Questions
Appendix: Company Financial Year-End → Filing Extension Deadlines (Block Extension Scheme)
Hong Kong Profits Tax returns generally must be submitted within 1 month of issuance, but the IRD offers a “Block Extension Scheme”, under which a tax representative can obtain an extended filing deadline based on the company’s financial year-end. Common arrangements are as follows (using the 2024/25 tax year return as an example, for reference only — actual annual deadlines are as published by the IRD each year):
| Financial Year-End Range | Year-End Code | Typical Extended Deadline |
| 1 April – 30 November | N code | Around early June of the following year |
| 1 December – 31 December | D code | Around mid-September of the following year |
| 1 January – 31 March (profit cases) | M code (Profits) | Around mid-December of the same year |
| 1 January – 31 March (loss cases) | M code (Loss) | Around early February of the following year |
