Hong Kong Pay Tax Guide: How to File and Pay Your Tax Return

Hong Kong's tax system is simple, but the timing catches many people out. Nothing is taken from your paycheck each month. Instead, you file a return once a year and pay the tax yourself in two lump sums. Miss a date and the Inland Revenue Department (IRD) can add surcharges or issue an estimated bill.

This guide walks through the full Hong Kong pay tax process for individuals. It covers who has to file, how to complete the return, and the key deadlines. It also explains how to read your tax bill and every way to pay it.

How the Tax Return Cycle Works

For most employees, Hong Kong personal income tax means salaries tax. It covers income from a job, an office such as a directorship, or a pension. How rates and allowances work is covered in our guide to [Hong Kong salaries tax rates](FUTURE-LINK: blog #1, Hong Kong salaries tax rates guide). This article focuses on filing and payment.

The tax year, called the year of assessment, runs from April 1 to March 31. Each year follows roughly the same pattern.

Your exact due dates are always printed on your tax bill, so check it carefully.

Do You Need to File a Return?

If the IRD sends you a tax return, you must complete and return it, even if you had no taxable income. Ignoring it can lead to penalties.

If you didn't receive a return but you earned taxable income, you still have a duty to act. You must tell the IRD in writing within four months after the end of the tax year. Individuals can use Form IR6167 for salaries tax. Non-residents paid for services in Hong Kong can use Form IR623R.

How to File Tax Return: Hong Kong Step by Step

Here's how to file tax return Hong Kong forms correctly, whether on paper or online.

Step 1: Gather Your Documents

Before you start, collect:

• The income statement your employer gives you, which is a copy of the IR56B employer's return
• Records of your mandatory MPF contributions
• Receipts for deductions, such as self-education, home loan interest, rent, or approved donations
• Details of dependants for any allowances you plan to claim
• Rental income records, if you own property that you let out

Step 2: Choose Paper or Online Filing

You can mail the paper form or file through eTAX. The IRD launched a new Individual Tax Portal and the eTax mobile app in July 2025. Filing online is faster, checks for common errors, and gives you an automatic one-month extension.

Step 3: Complete the Return

The BIR60 asks for your employment income, any property or business income, and the allowances and deductions you want to claim. Married couples also choose here whether to be assessed separately or jointly. If you have more than one type of income, you can also elect personal assessment on the return.

Report the gross income figures shown by your employer. Don't subtract your MPF contributions from salary. Claim them in the deductions section instead.

Step 4: Sign, Submit, and Keep Records

Sign the return and submit it before the deadline. If you post it, allow enough time and use the correct postage. Keep your receipts and working papers, since the IRD can ask for proof of any claim later.

Salaries Tax Filing Deadline for 2025/26

The IRD issued 2025/26 individual tax returns on May 4, 2026. The salaries tax filing deadline depends on your situation and how you file.

Sole proprietors report their business profits on the same return, which is why they get extra time. If you're weighing that structure against a company, our guide on sole proprietorship vs limited company in Hong Kong compares the two.

If you need more time, you can apply to the IRD for an extension before the deadline. A tax representative can also often secure later dates for clients.

If You Miss the Deadline

A late or missing return can lead to penalties, and continued non-compliance can lead to prosecution. The IRD may also issue an estimated assessment, which can be higher than your real tax. If this happens, file the return as soon as possible and contact the IRD.

Understanding Your Tax Bill

After processing your return, the IRD sends a notice of assessment and demand for tax. It usually shows two amounts.

Final Tax and Provisional Tax

Final tax is the balance you owe for the year you just reported. Provisional tax is an advance payment for the current year, usually based on your latest income. When the next year's final assessment comes out, the provisional tax you paid is credited against it.

Most bills split payment into two instalments. The first covers the final tax plus most of the provisional tax. The second covers the rest of the provisional tax a few months later.

If you believe the assessment is wrong, you can lodge an objection in writing within one month of the date of the notice.

Holding Over Provisional Tax

If your income is falling, you may be able to pay less provisional tax. The most common reason is that your expected net chargeable income for the current year will be less than 90% of the previous year's. Other grounds include stopping work, becoming entitled to a new allowance, or having objected to the previous assessment.

The application must be made in writing. It must reach the IRD by the later of two dates. The first is 28 days before the payment due date, and the second is 14 days after the bill was issued. For example, the IRD's own guidance shows a bill issued on August 5, 2026 with a first instalment due on January 4, 2027. The holdover deadline for that instalment is December 7, 2026. Individuals can apply online or use Form IR1121.

Hong Kong Pay Tax Methods

The ways to pay tax HK taxpayers use most are electronic, and many work around the clock.

Each bill has its own account number, so use the right one for every payment. Electronic services have daily cut-off times and transaction limits, so check yours before the due date. Overseas taxpayers can find transfer instructions on the IRD's payment pages.

If You Can't Pay on Time

Don't ignore the bill. The IRD can add a 5% surcharge to tax not paid by the due date. If the amount is still unpaid six months later, a further 10% surcharge can be added. The IRD can also take recovery action, such as asking your employer or bank to pay the amount you owe.

If you're facing financial difficulty, apply to the IRD for payment by instalments as early as possible. Before you pay tax, HK taxpayers who expect a problem should contact the IRD before the due date, not after.

Income Tax in Hong Kong for Expats: Arriving and Leaving

Income tax in Hong Kong for expats follows the same filing rules as for local residents. A few extra points apply when you arrive or leave.

When You Arrive

You may not receive a tax return automatically for your first year. If you haven't received one but earned taxable income, notify the IRD within the four-month limit. Relocating staff should sort out their tax position at the same time as their Hong Kong employment visa.

When You Leave

If you're leaving Hong Kong for good or for a long period, your employer must notify the IRD at least one month before you go. The employer must then hold back money owed to you until you show a letter of release from the IRD. To get it, settle your tax bill before departure. Also give the IRD a forwarding address so later notices reach you.

Staying on Top of Your Tax Each Year

Most tax problems in Hong Kong come from missed dates rather than complex rules. Put the return deadline and both payment dates in your calendar as soon as your documents arrive. Set money aside each month so the January bill isn't a shock.

Employers have their own yearly filings, covered in our Hong Kong company annual compliance guide. If you run a company and want help with employer returns or payroll records, our accounting and bookkeeping team can prepare them. For personal or business tax questions, our tax advisory team can review your position.

Frequently Asked Questions

Q: Can I file my Hong Kong personal income tax return online?

Yes. You can file through eTAX using the IRD's Individual Tax Portal or the eTax mobile app. Online filing checks for common errors as you go, and it automatically gives you one extra month compared with the paper filing deadline.

Q: What is the salaries tax filing deadline if I file on paper?

It's usually one month from the date the return is issued. For 2025/26, returns were issued on May 4, 2026, so most paper returns were due by June 4, 2026. Sole proprietors with business income had until August 4, 2026.

Q: Why is my tax bill higher than I expected?

The bill usually includes provisional tax for the current year on top of the final tax for last year. That can make the first bill feel large. If your income is dropping, you may be able to hold over some provisional tax.

Q: Can I pay my Hong Kong tax by credit card?

The IRD doesn't list credit cards among its standard payment methods. Most people pay by FPS, internet banking, PPS, ATM, or at a convenience store. Some banks may offer other bill payment options, so check with your own bank directly.

Q: What happens if I leave Hong Kong without paying my tax?

Your employer must hold back money owed to you until the IRD issues a letter of release. Unpaid tax can also attract surcharges and recovery action. Settle your bill and give the IRD a forwarding address before you go.
