Hong Kong Annual Compliance Guide: Audit, Profits Tax Return, NAR1 & Business Renewal

Hong Kong continues to rank among the most efficient corporate jurisdictions globally. However, once a company is incorporated, ongoing compliance becomes a statutory obligation — not an option.

Every Hong Kong private limited company must carefully manage four core annual obligations:

1. Statutory Audit

2. Profits Tax Return (PTR) Filing

3. NAR1 Annual Return Submission

4. Business Registration Certificate (BRC) Renewal

Failure in any one area may trigger penalties, estimated tax assessments, or prosecution.

This guide provides a clear, regulator-aligned compliance roadmap for directors, shareholders, and overseas founders.

1. Statutory Audit Requirement (Companies Ordinance – Cap. 622)

Under the Hong Kong Companies Ordinance, every incorporated company must:

• Prepare annual financial statements

• Have those statements audited by a Hong Kong Certified Public Accountant (CPA)

• Present audited accounts to shareholders

There is no general small-company audit exemption for standard private companies.

Audit applies even if:

• The company has no revenue

• The company incurred losses

• Operations occurred outside Hong Kong

Exception: A company formally declared dormant under Section 5 of the Companies Ordinance may qualify for audit exemption, provided strict procedural requirements are met.

2. Profits Tax Return (PTR) – Filing with Inland Revenue Department

The Profits Tax Return is issued by the Inland Revenue Department (IRD).

When Is It Issued?

• First PTR: approximately 18 months after incorporation

• Bulk issuance cycle: typically April each year

What Must Be Filed?

A complete PTR submission includes:

• Completed Profits Tax Return form

• Audited financial statements

• Tax computation

• Supporting schedules (if applicable)

Even if the company has:

• No business activity

• No income

• Accounting losses

A return must still be filed.

Profits Tax Rates (Corporations)

Hong Kong operates a two-tier regime:

• 8.25% on first HKD 2 million of assessable profits

• 16.5% on profits exceeding HKD 2 million

Important compliance nuance:

• The two-tier benefit applies to only one entity within a connected group

• Offshore claims do not remove the obligation to file

• Loss-making companies must still submit audited accounts

3. Filing Deadlines & Block Extension Scheme

For companies represented by tax agents, IRD applies a Block Extension Scheme.

Deadlines vary depending on:

• Accounting year-end date

• Profit or loss position

• Annual IRD circular letter

Companies without representation typically must file within one month from the date of issue.

Failure to file may result in:

• Estimated tax assessment

• Additional tax surcharge

• Prosecution

4. NAR1 Annual Return – Companies Registry Filing

Form NAR1 must be filed annually with the Companies Registry.

Filing Deadline

• Within 42 days after the company’s incorporation anniversary

• Anniversary = date of incorporation (not financial year end)

Information Confirmed in NAR1

• Registered office address

• Directors

• Company secretary

• Share capital

• Shareholders

Late filing triggers statutory escalating fees.

Persistent non-compliance may lead to prosecution of responsible persons.

5. Business Registration Certificate (BRC) Renewal

The Business Registration Certificate is administered by the Inland Revenue Department.

Renewal Frequency

• Valid for 1 year or 3 years (if elected)

• Must be renewed before expiry date

Fees are gazette annually and subject to change.

Failure to renew may result in fines and court proceedings.

6. Dormant Company – What It Really Means

Dormancy is not automatic.

To qualify:

• Special resolution must be passed

• Filing must be made with Companies Registry

• No accounting transactions may occur

If properly declared:

• Audit exemption may apply

• Compliance obligations reduce

However:

• IRD may still issue Profits Tax Returns

• Any transaction invalidates dormancy

Improper dormancy claims carry risk.

7. Common Compliance Risks

• Confusing NAR1 anniversary with financial year end

• Delaying bookkeeping until PTR is issued

• Assuming “no activity” removes audit obligation

• Missing Business Registration expiry date

• Ignoring estimated assessments

Hong Kong regulators increasingly rely on digital monitoring and cross-agency data review.

8. Hong Kong Annual Compliance Checklist 

✔ Maintain proper accounting records (minimum 7 years)

✔ Close accounts promptly after year end

✔ Complete statutory audit

✔ File Profits Tax Return with audited accounts

✔ Submit NAR1 within 42 days of incorporation anniversary

✔ Renew Business Registration before expiry

Conclusion

Hong Kong’s corporate compliance framework is clear, structured, and strictly enforced.

Audit, Profits Tax Return, NAR1 filing, and Business Registration renewal operate independently and on different timelines. Directors must manage each obligation proactively to maintain good standing.

Disciplined compliance planning is essential to ensure:

• Regulatory protection

• Tax certainty

• Banking stability

• Long-term corporate credibility
