In Hong Kong, an Unlimited Company—operating either as a Sole Proprietorship or a Partnership—is registered solely with the Inland Revenue Department's Business Registration Office (BRO) under the Business Registration Ordinance (Cap. 310). Because an unlimited business is not an incorporated body corporate under the Companies Ordinance (Cap. 622), it does not possess a Certificate of Incorporation (CI), Articles of Association, or Form NNC1/NAR1. Many online shop owners, retail proprietors, and independent consultants mistakenly attempt to use personal savings accounts (or personal FPS/PayMe) to collect commercial revenue—a practice that directly breaches retail banking terms and triggers Anti-Money Laundering (AML, Cap. 615) account restrictions.
Authored by the Banking Compliance Division of Licensed TCSP (TC006431), this practical guide details: ① Statutory differences between Unlimited (Cap. 310) and Limited (Cap. 622) corporate accounts; ② Mandatory IRD documents: Business Registration Certificate (BRC) and Certified Extract of Information on the Business Register (Form 1(a) / Form 1(c)); ③ 2026 policy & fee comparison across 6 mainstream HK banks (ZA Bank Business, HSBC Sprint, Hang Seng Virtual+, BOCHK, OCBC HK, PAObank); ④ E-commerce & studio substance proof standards; and ⑤ KYC/CDD verification and tax segregation rules.
I. Statutory Framework: Unlimited Business (Cap. 310) vs. Limited Company (Cap. 622) Banking
Before submitting a business account application, proprietors must understand how Hong Kong banks classify legal entities. While a Hong Kong Private Limited Company is registered with the Companies Registry (CR) and verifiable via ICRIS statutory filings, an unlimited firm exists exclusively on the Business Register maintained by the Inland Revenue Department (IRD).
| Compliance Dimension | Unlimited Business (Sole Proprietorship / Partnership) | Private Limited Company (Body Corporate) |
|---|---|---|
| Governing Statute | Business Registration Ordinance (Cap. 310) & Partnership Ordinance (Cap. 38) | Companies Ordinance (Cap. 622) & Business Registration Ordinance (Cap. 310) |
| Primary Registry | Inland Revenue Department — Business Registration Office (BRO); 8-digit BRN only | Companies Registry (CR No.) + Inland Revenue Department (8-digit BRN) |
| Core Statutory Proof for Bank CDD | Valid Business Registration Certificate (BRC) + IRD Certified Extract of Information on the Business Register (Form 1(a) or Form 1(c)) | Certificate of Incorporation (CI), Business Registration Certificate (BRC), Form NNC1 / NAR1, Articles of Association (AA) |
| Legal Liability & Account Title | Proprietor(s) bear unlimited personal liability; bank account is opened in the registered business trade name (e.g., "ABC Trading Co." or "Chan Tai Man T/A ABC Studio") | Separate legal personality; limited liability; account opened strictly in the statutory corporate name ending with "Limited" |
| Bank Company Search Fee | HK$ 0 – HK$ 1,200 (Simpler single-layer ownership structure) | HK$ 0 (Digital Banks) to HK$ 1,200 – HK$ 10,000 (Traditional banks, depending on corporate shareholding layers) |
| Profits Tax Rate (Two-Tiered) | 7.5% on first HK$ 2,000,000 assessable profits; 15% thereafter (Unincorporated business rate) | 8.25% on first HK$ 2,000,000 assessable profits; 16.5% thereafter (Corporation rate) |
Under standard retail banking terms (e.g., HSBC One, BOCHK Integrated Account, Hang Seng Integrated Account) and the HKMA Guideline on Anti-Money Laundering and Counter-Financing of Terrorism, personal accounts are restricted strictly to personal salary, savings, and investment use. Receiving high-frequency third-party FPS transfers, personal PayMe commercial collections, or e-commerce settlement payouts into a personal account will trigger automated transaction monitoring alerts, leading to compliance inquiries and potential account termination. Opening a dedicated business account under your Cap. 310 Business Registration Certificate is the statutory solution.
II. Mandatory Statutory Dossier: BRC & IRD Certified Extract (Form 1(a) / Form 1(c))
A common reason unlimited company applicants are turned away at bank branches is bringing only the one-page Business Registration Certificate (BRC). Because the BRC itself only displays the Business Name, Address, Nature of Business, and BRN—without listing the proprietor's or partners' identity card numbers and residential addresses—banks cannot verify ownership from the BRC alone.
To satisfy Customer Due Diligence (CDD) under Schedule 2 to the AMLO (Cap. 615), banks require the following statutory documents:
- 1. Valid Business Registration Certificate (BRC): Must be within its validity period with the statutory levy paid in full. If your business operates under a trade name / branch name, the Branch Registration Certificate must also be presented.
- 2. Certified Extract of Information on the Business Register: Issued by the Inland Revenue Department (via GovHK eTAX or 4/F, Inland Revenue Centre, Kai Tak). This is the official certified copy of your initial registration application:
- Form 1(a): Applicable to a Sole Proprietorship, certifying the sole proprietor's full legal name, HKID/Passport number, and residential address.
- Form 1(c): Applicable to a Partnership, certifying the full particulars of all general and limited partners.
- 3. Partnership Agreement (Partnerships Only): For firms with 2 or more partners, banks require a signed Partnership Deed specifying profit-sharing ratios, capital contributions, and banking signatory authority (whether single partner signature or joint signatures are required).
- 4. Identity & Residential Address Proof of Proprietor / Partners: HKID Card (and valid Exit-Entry Permit / Passport for non-residents) plus residential address proof issued within the last 3 months (utility bill, bank statement, or government tax demand note) for the sole proprietor or all partners holding 25% or more interest.
III. 2026 Hong Kong Banks Accepting Unlimited Companies: Policy & Tariff Matrix
Not every commercial bank treats unlimited businesses equally. Moreover, several digital banks distinguish between HKID-holding sole proprietors and multi-partner firms. Compare the 2026 onboarding parameters below (for a broader comparison including limited companies, see our Virtual vs. Traditional Corporate Bank Account Comparison):
| Bank & Clearing Code | Account Tier | Eligibility (Sole Prop. vs. Partnership) | Account Opening / Search Fee | Min. Balance & Monthly Fee Waiver |
|---|---|---|---|---|
| ZA Bank (387) | ZA Bank Business Account | Sole Proprietorship & Partnership (HKID holders; 100% mobile/web onboarding) | HK$ 0 – HK$ 1,200 (Standard local CDD fee; often waived under startup promos) | HK$ 0 minimum balance; HK$ 0 monthly maintenance fee |
| HSBC HK (004) | HSBC Business Sprint | Sole Proprietorship & Partnership registered in HK (<3 years old) | HK$ 1,300 (Online application) / HK$ 1,600 (Branch) | HK$ 0 monthly fee for first 12 months; thereafter HK$ 50,000 TRB waives HK$ 200/mo |

| PAObank (392) | Digital Business Account | Sole Proprietorship & Partnership (HK local SMEs & retail merchants) | HK$ 0 | HK$ 0 minimum balance; HK$ 0 monthly maintenance fee |
IV. Business Substance Proof Checklist for Online Shops, Retail Studios & Freelancers
Whether you operate a Shopify/Instagram e-commerce store, a retail boutique, a design consultancy, or a tutorial center, bank relationship managers must verify genuine commercial substance. Prepare at least 2 to 3 items from the following category-specific checklist:
- For E-Commerce & IG / Social Commerce Merchants:
- Live storefront URL (Shopify, Shopline, HKTVmall, Amazon, or active Instagram/Facebook commercial page showing product catalog and pricing);
- Merchant settlement statements from payment gateways (Stripe, PayPal, PayMe for Business, AlipayHK/WeChat Pay HK merchant backend) or logistics waybills (SF Express monthly statement);
- 1 to 2 supplier purchase invoices or inventory procurement receipts matching the goods sold.
- For Independent Consultants, Designers & Service Studios:
- 1 to 2 signed client service agreements, engagement letters, or official quotations/invoices;
- Professional portfolio, qualification certificates, or previous employment/project track record in the same industry;
- Personal bank statements from the past 3–6 months demonstrating historical project income or initial working capital.
- For Physical Retail, F&B & Offline Shops:
- Stamped commercial tenancy agreement or co-working studio membership contract (see our Registered & Operating Address Compliance Guide);
- Photographs of the shopfront signage, interior inventory, and POS terminal setup;
- Relevant industry licenses (e.g., FEHD food license, retail distributor authorization) where applicable.
V. Customer Due Diligence (KYC/CDD) Verification & Tax Accounting Rules
During the onboarding review (either in-branch or via digital bank video/document check), compliance officers evaluate three primary dimensions under Cap. 615:
- 1. Consistency Between BRC "Nature of Business" and Actual Operations: Check your BRC under "Nature of Business". If it displays
CORPor a generic term that conflicts with your actual e-commerce or consulting contracts, submit form IRC 3110A to the IRD to update the business nature before applying to the bank. - 2. Source of Initial Capital & Expected Turnover Declaration: Declare your realistic monthly revenue and transaction volume based on actual orders. Avoid exaggerating projected turnover into tens of millions of HKD without supporting contracts, as disproportionate projections trigger Enhanced Due Diligence (EDD).
- 3. Accounting Segregation & Upgrade Path to Limited Company: Although an unlimited company is not legally required to appoint a CPA for statutory audit under Cap. 622 (unless total gross income exceeds HK$ 2,000,000 requiring certified accounts attachment for tax filing), the Inland Revenue Ordinance (Cap. 112 s.51C) mandates keeping complete business records for at least 7 years. Keep all business receipts and expenses strictly within this dedicated business account. When annual profits grow or when you need to onboard institutional investors, follow our Unlimited Company to Limited Company Conversion SOP.
VI. Frequently Asked Questions (FAQ)
Because an unlimited company (sole proprietorship or partnership) is established under the Business Registration Ordinance (Cap. 310) rather than the Companies Ordinance (Cap. 622). It is regulated by the Inland Revenue Department's Business Registration Office (BRO), not the Companies Registry. Therefore, to prove your ownership to a bank, you must apply to the IRD for a Certified Extract of Information on the Business Register (Form 1(a) or Form 1(c)).
You can apply online 24/7 via the GovHK eTAX portal ("Application for Supply of Information on the Business Register"). Select the "Certified Extract of Information" for your 8-digit BRN. The statutory government fee is HK$ 45 per copy, and it is typically ready for download or collection by the next working day. Most Hong Kong banks require the extract to be issued within the last 3 to 6 months.
Yes. Both digital banks (such as ZA Bank Business and PAObank) and startup-focused commercial tiers (such as HSBC Business Sprint and Hang Seng Business Virtual+) accept newly registered unlimited businesses. Since a new shop has no historical tax returns, you should provide your live online store URL, product procurement receipts, and the proprietor's personal bank statements showing startup capital.
In general, all partners holding 25% or more voting rights or profit share (as well as all authorized account signatories) must complete identity verification. At traditional banks (HSBC, BOCHK, Hang Seng), all principal partners and authorized signatories should attend the commercial center appointment together with the original Partnership Agreement and Form 1(c).
Yes. Once your unlimited company opens a business account with HSBC, you can immediately apply for PayMe for Business to collect payments from retail customers via QR code or payment link without violating personal PayMe rules. All Hong Kong business accounts also support registering a commercial FPS Proxy ID for instant HKD/RMB clearing.
No. Under Hong Kong law, an unincorporated sole proprietorship/partnership and an incorporated Private Limited Company are completely distinct legal entities with different Business Registration Numbers (BRNs). When upgrading to a Limited Company, you must open a new corporate bank account under the Limited Company's CI and BRC, and then transition your business operations accordingly.
