How to File and Pay Taxes in Hong Kong: 2026 Guide

The Inland Revenue Department does not send reminders. It sends a return, waits, and then charges you.

That is the single most useful thing to understand about Hong Kong tax filing, and it catches out foreign-owned companies more than any technical rule does. The deadlines are not aggressive, the forms are not complicated, and the rates are low. What goes wrong is that nobody in the company is watching for an envelope that arrives once a year at a registered office they have never visited.

This guide covers how to file and pay taxes in Hong Kong from both sides: the profits tax return your company files, and the individual return you file if you draw a salary there. It covers procedure rather than rates, and every figure in it is taken from the Inland Revenue Department rather than from other guides.

In short: A Hong Kong company files a profits tax return each year, normally with audited accounts and a tax computation attached. The IRD issues returns in early April and the filing window is usually one month, extendable through a tax representative. Tax is paid after assessment, not at filing, and late payment carries a 5% surcharge.

Which returns does your company actually have to file?

Most Hong Kong companies deal with three separate returns, issued by different parts of the system at different times of year, and confusing them is common.

A company with no employees in Hong Kong still files a profits tax return. A company with staff files the employer's return as well, and that one runs on its own calendar, issued in early April with a one-month window that does not move with your accounting date. The individual return is yours personally rather than the company's, and it is the one most non-resident directors never receive, because they draw no Hong Kong salary and so have nothing to report.

Unincorporated businesses, meaning partnerships and sole proprietorships, use BIR52. Non-resident persons chargeable to profits tax use BIR54, which is the one that occasionally applies to an overseas entity trading into Hong Kong without a local company.

The distinction matters because the deadlines differ, and missing one does not excuse the others.

When do Hong Kong tax returns arrive and when are they due?

The IRD bulk-issues profits tax returns in early April each year, and individual returns in early May. The standard filing window is one month from the date of issue. Companies represented by a tax representative can get substantially longer under the block extension scheme, which is the main reason most foreign-owned companies appoint one.

The extension depends on your accounting year-end, which the IRD sorts into three codes:

• Code N: accounting date between 1 April and 30 November
• Code D: accounting date in December
• Code M: accounting date between 1 January and 31 March

Each code gets a different extended deadline, electronic filing generally adds further time, and companies in a loss position can apply for longer again.

Here is the part worth taking seriously: the exact dates change every year, and published tables get them wrong. While researching this guide we compared several widely-read sources against the IRD's own circular letter to tax representatives. For Code D returns, the circular gives an extended date of 31 August 2026 for paper filing and 2 October 2026 for electronic filing. At least one well-known guide publishes different dates for the same code.

Read the dates from the IRD's Block Extension Scheme page for the current year, or ask your tax representative, and treat any blog table as a prompt to check rather than an answer.

One timing point that surprises new companies: your first profits tax return usually arrives around eighteen months after incorporation, not at the end of your first year, and it typically comes with a longer filing window than subsequent ones.

That gap is generous and it is also a trap. Eighteen months of transactions have to be reconstructed and audited at once, and a company that has not kept books since day one discovers the scale of the job only when the return lands. The cost of a first audit is routinely higher than subsequent years for exactly this reason.

Filing a profits tax return, step by step

Step 1: Close your accounts for the basis period. Your basis period is normally the twelve months ending on your accounting date. Get bookkeeping finished early, because everything downstream waits on it.

Step 2: Get the accounts audited. A Hong Kong limited company needs financial statements audited by a Hong Kong-registered CPA. There is no small-company exemption and no zero-revenue exemption. Only formally dormant companies are outside this. Our guide to Hong Kong audit requirements covers who needs one and what it involves.

Step 3: Prepare the tax computation. This reconciles accounting profit to assessable profit, adjusting for items treated differently under tax law, such as depreciation replaced by tax allowances.

Step 4: Complete the return and any supplementary forms. The main return is short. Most of the detail sits in supplementary forms, which cover specific matters such as preferential tax regimes, transfer pricing, and foreign-sourced income falling under the exemption rules. Only some apply to any given company, but working out which ones do is easier before you start than halfway through.

Before you begin filling anything in, gather:

• Audited financial statements for the basis period, signed by the auditor
• The tax computation reconciling accounting profit to assessable profit
• Prior year's assessment, for comparison and for provisional tax figures
• Details of any offshore income you intend to claim, with supporting evidence
• Records of any preferential regime you are relying on

Step 5: File, with the accounts and computation attached. Most companies must submit audited accounts and the tax computation alongside the return.

Step 6: Wait for the assessment. Filing is not paying. The IRD reviews the return and issues a notice of assessment, also called a demand note, telling you what to pay and when.

If you are claiming that profits are sourced outside Hong Kong, you still complete and file the return. An offshore profits claim is made through the return and supported with evidence, not by leaving the return unfiled.

The IRD may follow up with written enquiries after the return goes in, sometimes months later, asking where contracts were negotiated, where the work was performed and who performed it. Those enquiries have response deadlines of their own. Treating the filing as the end of the matter, rather than the start of a conversation, is how otherwise sound offshore claims get refused.

Filing your individual return

If you receive a BIR60, the sequence is shorter.

Your employer files its return on BIR56A with an IR56B for each employee, reporting what it paid you. The IRD then issues your BIR60, typically in early May. You complete it, claim your allowances and deductions, and submit within the window shown on the form. Sole proprietors get a longer period than employees.

Most non-resident owners of Hong Kong companies never receive a BIR60, because they take dividends rather than a Hong Kong salary and have no Hong Kong employment income to report. If you do draw a salary, the rates and allowances are covered in our Hong Kong salaries tax guide.

Can you file Hong Kong tax returns online?

Yes. The IRD runs eTAX for individuals and electronic filing for profits tax returns, and electronic submission generally buys additional time over paper filing under the block extension scheme.

The practical obstacle for non-residents is registration rather than the filing itself. Setting up access requires identity verification, which is straightforward for a Hong Kong ID holder and less so for someone abroad.

In practice most foreign-owned companies file through a tax representative, who submits on the company's behalf through the Tax Representative Portal. That is also what unlocks the longer block extension deadlines, so for a non-resident owner the representative is doing two jobs at once.

What is provisional tax, and can you reduce it?

Hong Kong charges provisional tax: an advance payment towards the current year, calculated on the previous year's assessable profits, billed at the same time as the final tax for the year just assessed. The first year a company becomes profitable therefore produces a bill covering both the year assessed and an advance on the next.

That double hit is the most common cash flow shock in Hong Kong tax, and it is entirely predictable once you know it is coming.

If your circumstances have changed, you can apply to hold over provisional tax, meaning defer or reduce it. Grounds include assessable profits being substantially lower than the amount used to calculate the provisional charge, the business having ceased, or an objection being lodged against the underlying assessment.

Holdover has its own deadline, which falls a set period before the tax is due, and an application made after that point will not help you. A company whose profits have dropped sharply and which does nothing will simply be billed on last year's better figures.

This is the section the previous version of this guide left out, and it is probably the most financially useful paragraph on this page.

How do you pay Hong Kong tax?

Payment is due on the date shown on the notice of assessment, not on the filing date. The Inland Revenue Department accepts payment by several methods:

• Internet: through the IRD website and linked government payment services
• PPS: by phone, using the IRD merchant code
• Bank ATM: at machines displaying bill payment functionality
• In person: at post offices, by cash, cheque or EPS
• By post: cheque to the Commissioner of Inland Revenue

Paying from overseas is where non-resident owners run into friction. There is no difficulty with the payment itself, but several of these routes assume a Hong Kong bank account or a local presence. Companies banking through a payment provider rather than a traditional bank should confirm the route works well before the due date rather than discovering it in the final week.

What happens if you file or pay late?

Late payment is the more mechanical of the two. The IRD imposes a 5% surcharge on tax still unpaid after the due date, and a further 10% surcharge on any amount still outstanding six months later.

Beyond surcharges, the department states it may commence recovery action without prior notice. That includes issuing notices to third parties who hold money for you, such as your bank, your tenants or your employer, requiring them to pay the department directly, and pursuing the debt through the District Court.

Late filing is handled separately, through prosecution provisions and additional tax assessed as a penalty. Published figures for these amounts vary between sources, so rather than repeat a number that may be wrong, check the current position with the IRD or your representative. The mechanism matters more than the number: the penalty scales with how late you are and how much tax was involved.

If you genuinely cannot pay on time, you can apply for an instalment arrangement. Worth knowing before you rely on it: the IRD is explicit that surcharges still apply to tax remaining unpaid after the due date even where an instalment application is approved. An arrangement manages the cash flow, it does not remove the cost.

What if the assessment is wrong?

An assessment is not final the moment it arrives. If the figures do not match your return, or the IRD has issued an estimated assessment because it did not receive one, you can object.

Estimated assessments are the common case for companies that missed a filing. The department does not wait indefinitely: it estimates the profit, assesses tax on that estimate, and the resulting demand note is enforceable even though the number is invented. Companies sometimes receive a bill far larger than their actual liability and assume it must be a mistake that will correct itself. It will not.

An objection has to be made in writing within a set period from the date of the notice, stating the grounds precisely. Two points decide whether it works:

1. File the outstanding return alongside the objection. An estimated assessment exists because a return is missing, and objecting without supplying one rarely resolves anything.
2. Deal with the tax in the meantime. Lodging an objection does not automatically suspend the obligation to pay. You can apply to hold over the tax in dispute, but that is a separate application with its own conditions, and surcharge exposure continues if it is refused.

The practical lesson is the same one that runs through this whole process. The system moves on a schedule whether or not anyone at the company is paying attention, and the cost of re-entering the conversation late is always higher than the cost of being on time.

The remote owner's problem, and how to avoid it

Everything above assumes someone sees the return. For a company whose director lives in Almaty or Tbilisi, that assumption is where compliance usually breaks.

The return goes to the registered office in Hong Kong. If that address belongs to a corporate services provider, whether it reaches you depends on the arrangement you have with them, and some forward post reliably while others hold it until asked.

Three things prevent almost all of it:

1. Confirm in writing how your registered office handles IRD correspondence, and how quickly.
2. Diarise your accounting date, then work backwards: audit booked three months ahead, computation after that, filing before the deadline.
3. Appoint a tax representative if you are not in Hong Kong. It buys the extension and gives the IRD someone who answers.

The second failure mode is subtler. Companies claiming offshore treatment sometimes stop treating the filing as urgent, reasoning that no tax is due. The return is still required, the deadline still applies, and a late filing weakens the credibility of the claim it carries. The full annual cycle is set out in our guide to annual compliance for Hong Kong companies.

Frequently asked questions

When is the Hong Kong profits tax return due?

Profits tax returns are normally issued in early April with a one-month filing window. Companies with a tax representative receive longer under the block extension scheme, with the date depending on the accounting year-end code. Electronic filing generally adds further time.

Does a company with no profit still have to file?

Yes. A profits tax return must be completed and filed whether the company made a profit, made a loss, or is claiming that its profits are sourced outside Hong Kong. Only formally dormant companies are treated differently, and dormancy is a narrow status.

What happens if I pay Hong Kong tax late?

A 5% surcharge applies to tax unpaid after the due date, with a further 10% on any amount still outstanding after six months. The Inland Revenue Department may also begin recovery action without prior notice, including notices to your bank or other third parties.

Can I pay Hong Kong tax from overseas?

Yes, though some routes assume a local account. Internet payment through the IRD's linked services is usually the most practical option for a non-resident. Confirm your chosen method works before the due date, particularly if you bank with a payment provider rather than a traditional bank.

What is provisional tax and can I reduce it?

Provisional tax is an advance payment for the current year, based on the previous year's assessable profits and billed alongside the final tax. You can apply to hold it over if profits have fallen substantially or the business has ceased, but the application has its own deadline.

Getting the cycle under control

Filing and paying tax in Hong Kong is not difficult once the calendar is set. The system issues returns predictably, the forms are stable, and payment is straightforward. What makes it go wrong for foreign-owned companies is distance: a return arriving at an address nobody checks, an audit booked too late, or a provisional tax bill nobody budgeted for.

Two habits solve most of it. Work backwards from your accounting date rather than forwards from the return, and appoint a tax representative if you are not in Hong Kong, which both extends your deadline and gives the department someone to deal with.

One caution on the specifics. Deadline dates shift every year, and published tables, including some from well-known providers, do not always match the IRD's own circular. Verify dates against the Inland Revenue Department for the year you are filing.
