Mastering Provisional Tax in Hong Kong: Complete Guide

What is provisional tax in Hong Kong? It is a prepayment of income tax based on your estimated earnings for the next assessment year. The Inland Revenue Department (IRD) uses this system to ensure a steady flow of tax revenue while spreading taxpayers’ obligations more evenly. However, many individuals and businesses misunderstand how provisional tax works, leading to overpayment or even penalties.

If you’ve ever wondered why you’re paying tax before earning income, here is the article for you. Let’s explore how provisional tax Hong Kong is calculated and how the holdover mechanism reduces or defers payment when your income declines.

What is provisional tax and why is it charged?

Paying tax before earning income may sound unusual, but provisional tax is a key part of Hong Kong’s tax system.

What is provisional tax Hong Kong

Provisional tax in Hong Kong is an advance payment of income tax based on your previous year’s taxable income. Instead of waiting until the end of the next assessment year, the Inland Revenue Department (IRD) estimates your upcoming income and collects tax in advance to align with your expected earnings.

This system applies to three major tax categories:

• Salaries tax for individuals
• Profits tax for businesses
• Property tax for landlords

The provisional tax is later adjusted against your final tax assessment once the actual income is reported. If you have overpaid, the excess will be refunded or used to offset the next year’s provisional tax.

Simply put, the final assessment reflects your actual income for the year, while provisional tax represents a forecast based on past figures. The two payments are interrelated but serve different timing purposes.

Purpose of charging provisional tax in Hong Kong

The government’s rationale for charging provisional tax lies in maintaining stable cash flow and timely tax collection. Hong Kong operates under a pay-later income tax system, where taxes are typically settled after the end of the financial year. Without provisional tax, large volumes of payments would arrive at once, creating pressure on both taxpayers and the IRD. By collecting tax in advance, the government secures a steady flow of revenue to fund essential public services such as healthcare, education, and infrastructure throughout the year.

From a taxpayer’s perspective, the provisional tax system also helps distribute the payment burden more evenly. Instead of settling the entire liability at once, individuals and companies pay in two installments, easing the impact on their finances. According to the IRD, the first installment usually equals 75 percent of the provisional tax, with the remaining 25 percent due later in the year.

In short, provisional tax HK plays a vital role in keeping Hong Kong’s income tax system efficient and predictable. At the same time, it allows adjustments through the final assessment once the actual income is confirmed.

How to calculate provisional tax in Hong Kong 

As stated, calculating provisional tax in Hong Kong involves estimating the upcoming year’s tax liability based on the previous year’s assessable income. Here’s how to calculate provisional tax so you can manage payments efficiently and avoid overpayment or cash flow issues.

Standard calculation method

Provisional tax is computed using assessable income from the preceding year as a reference. The IRD assumes income for the following year remains similar unless there is valid evidence of change.

Provisional tax under salaries tax

Under salaries tax, provisional tax is based on net chargeable income after deductions and allowances, using the progressive rates below:

Net chargeable income (HK$)	Tax rate (%)
First 50,000	2
Next 50,000 (50,001–100,000)	6
Next 50,000 (100,001–150,000)	10
Next 50,000 (150,001–200,000)	14
Remainder (Above 200,000)	17

Alternatively, the IRD applies a standard rate of 15% on net income if it results in a higher amount. For instance, if a taxpayer’s net chargeable income is HK$1,200,000, the tax under progressive rates would total HK$163,000. However, applying the standard rate of 15% on the full amount results in HK$180,000. In this case, the IRD will charge HK$180,000 as provisional tax since it is the higher figure.

Provisional tax under profits tax

Under profits tax, the rate is 16.5% on assessable profits of corporations and 15% on unincorporated businesses. Property tax is charged at 15% on the net assessable value of rental income after allowable deductions.

For example, if an enterprise that reported HK$1,000,000 in assessable profits in the previous year, it will be charged HK$165,000 (1,000,000 × 16.5%) as provisional profits tax for the current year.

When the final tax assessment is issued, the provisional amount paid is deducted from the total liability. If the final tax amounts to HK$180,000, the taxpayer pays the HK$15,000 balance. If the final tax is HK$150,000, the HK$15,000 overpayment will be refunded or credited to the next year’s provisional tax.

Special considerations and exceptions 

Although the standard computation method applies in most cases, adjustments may be necessary. If income is expected to decline significantly due to a slowdown in business, employment changes, or reduced property returns, a holdover of provisional tax may be requested. The IRD will require supporting evidence like financial statements or employment termination letters to process the application.

Furthermore,new taxpayers or those with new income sources are assessed differently. Without a prior-year record, the IRD estimates income for the first year and adjusts the figure once the actual amount is reported.

Estimates may not always reflect the current financial situation, particularly in changing economic conditions. This is why reviewing assessable income regularly with expert services, and notifying the IRD of major variations are crucial steps to make sure that provisional tax payments are accurate.

When and how is provisional tax paid?

Provisional tax HK follows a structured payment schedule designed to make compliance straightforward for both individuals and businesses.

Payment schedule

The IRD typically issues a demand note for provisional tax between November and December. The note specifies your total tax payable, due dates, and payment instructions.

Provisional tax is usually paid in two installments:

• The first installment, which accounts for about 75 percent of the total amount, is due in December or January.
• The second installment, covering the remaining 25 percent, is generally due in April.

It is important to note that exact deadlines vary each year, so taxpayers should refer to their IRD demand note for the official payment dates. Moreover, employee taxpayers who have elected to settle tax through their employer under the “Tax Reserve Certificates Scheme” or through automatic deductions should still verify that payments align with the IRD requirements.

Payment methods

Hong Kong’s tax payment system is efficient and flexible. Taxpayers can settle their provisional tax through several channels, including:

• Online payment via the IRD’s eTAX portal or online banking
• Cheque payment sent by post or made in person at the Revenue Tower
• Payment through banks or ATMs, available at most local institutions
• Phone Payment Service (PPS), allowing payment by phone or the PPS website

All payments should reference the 11-digit Shroff Account Number stated on the demand note.

Late payment penalties

Failure to pay provisional tax on time may result in additional charges. First, the IRD imposes a 5 percent surcharge on any unpaid balance after the due date. If the tax remains outstanding after further notice, an additional 10 percent surcharge may then apply. Continued non-payment could also trigger recovery actions such as salary garnishment or bank account deductions.

Holdover of provisional tax explained 

What is the holdover of Hong Kong provisional tax? This mechanism allows taxpayers to request a reduction or deferral of their provisional tax when their income or profits are likely to decrease. Governed by Section 63 of the Inland Revenue Ordinance, it prevents overpayment and supports more accurate tax settlements.

As the holdover process is not automatic, taxpayers must apply to the Inland Revenue Department (IRD) before the payment due date.

Who can apply

The IRD accepts holdover applications from individuals, partnerships, and companies under certain conditions, such as:

• A decrease in income or profits in the current year compared to the previous year, often due to business downturns or changing market conditions.
• Significant loss carry-forwards that offset expected assessable profits.
• New businesses or recently incorporated companies that have not yet generated profits.
• Termination of business operations, retirement, or emigration that reduces taxable income in the following assessment year.

How to apply

Taxpayers must submit a written application to the IRD within the specified time limit stated on the demand note along with other supporting evidence. The date is typically before the due date of the second installment of provisional tax.

If the IRD accepts the application, the provisional tax may be fully or partially held over, depending on the estimated shortfall. If rejected, the taxpayer must still settle the tax as originally assessed, and interest may apply on any overdue amount

Key differences between the tax holdover and tax incentives

Tax holdover and tax relief or reduction serve different objectives within Hong Kong’s tax framework. In particular, tax holdover allows deferment or suspension of a provisional tax payment when projected income falls. It does not reduce the final tax liability.

Rather, the holdover adjusts payment timing to reflect changed circumstances. Meanwhile, tax relief or tax reduction lowers the total tax payable by granting allowances, deductions or credits, directly reducing the final assessed tax liability.

Key distinctions between the two:

• Purpose: Holdover focuses on matching payment timing to income changes, while relief/reduction aims to lower the amount of tax owed.
• Impact on tax amount: Holdover does not alter the amount owed. Relief or reduction decreases the amount payable.
• Timing benefit: Holdover fuels cash flow by delaying payments. The relief provides a permanent reduction in final liability.
• For example: an employee whose income drops can apply for a holdover, whereas a taxpayer claiming MPF deductions or personal allowances benefits from tax relief.

Knowing how each measure works will let taxpayers manage provisional tax in Hong Kong more effectively and plan finances with greater accuracy. Keep in mind to evaluate whether your circumstances justify a holdover application or qualify for relief or reduction.

Grounds and conditions for applying holdover

Applying for a holdover of provisional tax in Hong Kong requires valid reasons and compliance with specific IRD conditions.

Valid grounds accepted by the IRD

The Inland Revenue Department (IRD) recognizes several valid reasons for applying for a holdover of provisional tax. The most common is when income or profits for the current year are expected to be significantly lower than the previous year’s assessment. The situation often arises from reduced business activity, lower sales, or changes in employment income.

A taxpayer may also apply if tax is unlikely to be payable because of new deductions, allowances, or reliefs, such as additional MPF contributions or charitable donations. Another acceptable ground is when a business has ceased operations or is expected to make a loss in the current year. In addition, applications are valid if income is exempt or subject to double taxation under Hong Kong’s tax treaties.

Conditions to note when applying

Applications must be filed within 28 days from receiving the demand note or 14 days before the payment due date, whichever is earlier. Supporting documents, such as projected income statements, profit and loss accounts, or auditor’s reports, must accompany the application to substantiate the claim.

Approval is not automatic. The IRD assesses each case carefully and may approve a full or partial holdover depending on the evidence. Until approval is granted, the taxpayer must continue to pay any portion of provisional tax shown as payable.

Application process for holdover of provisional tax

Once a taxpayer confirms eligibility to apply for a holdover, the next step is completing the official application through the Inland Revenue Department (IRD).

How to submit an application

The IRD provides two specific forms for the process:

• Form IR1121 – for Salaries Tax
• Form IR1122 – for Profits Tax

These forms can be downloaded from the IRD website or completed online through eTAX, Hong Kong’s digital tax portal. The online option is often preferred as it provides faster processing and immediate confirmation of receipt. Applicants log in with their eTAX password or digital certificate, fill out the holdover form, upload the required files, and submit directly to the IRD.

Those choosing traditional submission methods can print the relevant IRD holdover form and send it by post or deliver it in person to the IRD office.

What happens after applying

After submission, the IRD reviews the information provided and may:

• Approve the holdover fully or partially
• Request further clarification or documents
• Reject the application if it does not meet the required standards

Taxpayers are advised to monitor their eTAX account or postal correspondence for updates. Unless notified otherwise, the provisional tax shown on the demand note must still be paid on time. If the holdover is approved, the IRD will issue a revised assessment reflecting the reduced amount. When the final tax assessment is completed, any overpayment will either be refunded or credited toward future tax liabilities.

Avoiding costly mistakes with Hong Kong provisional tax

Applying for a holdover provisional tax in Hong Kong can save unnecessary payments, but small mistakes lead to rejection or penalties.

Applying for holdover too late

Timing is one of the most common reasons for IRD rejection. Applications must reach the Inland Revenue Department within 28 days of receiving the demand note or 14 days before the payment due date, whichever is earlier.

Late submissions are automatically refused, even if the taxpayer has a valid reason. Thus, setting calendar reminders or preparing documents early helps you stay compliant.

Inadequate documentation

The IRD requires clear and credible proof to justify the application, and submissions without detailed backup are rarely approved. Hence, taxpayers should attach necessary figures, calculations, and written explanations to demonstrate how the expected income or profits differ from the prior year.

Eligibility misconceptions 6y

Not every decline in earnings qualifies for a holdover. The IRD assesses if the income or profit is “substantially less,” based on measurable data. For instance, minor drops in commission or temporary slowdowns may not meet the threshold. Applicants should evaluate their financial situation carefully and consult professionals like BBCIncorp if you are uncertain about eligibility.

Staying proactive, maintaining clear records, and keeping track with the IRD’s assessment criteria reduce the risk of rejection. Businesses that manage their applications correctly avoid unnecessary tax burdens and keep cash flow stable throughout the year.
