    What is Provisional Tax?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
    \n\t\t\t\t\t\t\t\t\t

    Provisional tax is a system under which tax for the following year is collected in advance based on the taxpayer\u2019s income in the previous year. Under the law, Salaries Tax, Property Tax, and Profits Tax all require payment of provisional tax for the next year. The calculation method and the actual amount of provisional tax are set out in detail in the notice of assessment. Therefore, after receiving a Salaries Tax, Property Tax, or Profits Tax demand note, taxpayers should verify the provisional tax amount as soon as possible.<\/p>

    How Provisional Tax (Advance Tax) Is Calculated<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
    \n\t\t\t\t\t\t\t\t\t

    Provisional tax is calculated based on the taxpayer\u2019s income in the previous year, with tax for the following year collected in advance.<\/p>

    For Salaries Tax, provisional tax is calculated based on the tax payable for the previous year<\/strong>.<\/p>

    Assume your Salaries Tax payable for the 2025\/26 year of assessment is $10,000. In principle, your provisional tax for the 2026\/27 year of assessment would also be $10,000. When you receive your Salaries Tax demand note, the Inland Revenue Department will set out the provisional tax and total tax payable in the Notice of Assessment and Demand for Payment for 2025\/26 and Provisional Tax for 2026\/27.<\/p>

    However, differences in tax rates and tax relief measures in each fiscal year will also affect the provisional tax amount. For example, in the 2025\/26 fiscal year, due to a tax reduction of $3,000, the provisional tax for 2026\/27 and the tax payable for 2025\/26 will differ by $3,000.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    Can I choose not to pay provisional tax?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
    \n\t\t\t\t\t\t\t\t\t

    No. Paying provisional tax is a tax obligation for companies and taxpayers. However, you may apply to defer provisional tax if you meet the relevant conditions.<\/p>

    Sections 63E (Deferral of Provisional Salaries Tax), 63J (Deferral of Provisional Profits Tax), and 63O (Deferral of Provisional Property Tax) of the Inland Revenue Ordinance (Cap. 112) provide that where the statutory conditions are met, companies and taxpayers may apply within the prescribed time limit to defer provisional tax online via eTAX<\/a>Individual Tax Portal<\/a>, or by submitting Form IR1121 to the Inland Revenue Department.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    \n\t\t\t\t\t\t\t\t\t

    Under section 63E of the Inland Revenue Ordinance, as provisional tax is based on this year\u2019s income or profits, if income decreases or expenses (deductions and allowances) increase, resulting in a reduction of 10% or more in the assessable net income or net profits, and relevant supporting documents are provided, the conditions for applying to defer provisional tax are met.

    Under section 63E of the Inland Revenue Ordinance, the conditions for deferring Salaries Tax mainly relate to changes in an individual\u2019s income and circumstances, including: income reduced compared with last year, unemployment or retirement, increased allowances, increased deductions, or an objection\/appeal against the previous year\u2019s assessment is in progress.<\/p>

    Income threshold: The estimated assessable income is less than, or may be less than, 90% of the assessable income for the preceding year.<\/p>

    Supporting documents: Applicants should provide relevant documents based on the reason, such as proof of unemployment, a termination letter, or a salary reduction notice issued by the employer.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

    Income threshold: The estimated assessable profits are less than, or may be less than, 90% of the assessable profits for the preceding year.<\/p>

    Supporting requirement: If the reason for deferral is reduced profits, the taxpayer must submit with the application a signed draft set of accounts covering not less than 8 months.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

    Correct Interpretation of Reduced Income, Profits, or Rent for Provisional Tax Deferral<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
    \n\t\t\t\t\t\t\t\t\t

    We have received many enquiries about reasons for applying to defer provisional tax, most of which stem from misunderstanding the correct interpretation of reduced income, profits, or rent. Many people misinterpret the percentage required by the Inland Revenue Department, believing that income must be 90% lower than in previous years to qualify. Below is the IRD\u2019s original wording with a detailed explanation:<\/p>

    \u201cYour assessable income for the year of assessment for which provisional tax is charged is less than, or may be less than, 90% of your assessable income for the preceding year, or is less than, or may be less than, 90%<\/em> of the estimated income for the year of assessment for which provisional tax is charged.\u201d<\/em><\/p>

    Source: GovHK \u2013 Deferral of Provisional Tax<\/a><\/p>

    In our experience, the public often mistakenly believes that income must drop by 90% to apply for deferral of provisional tax. The correct understanding is that income\/profits are 10% lower than in previous years; or that profits\/income are 90% of last year\u2019s level, which already meets the condition for reduced income or profits when applying to defer provisional tax.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    Will provisional tax be refunded?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t

    It may be. For example, if a taxpayer\u2019s assessable income for the year of assessment drops significantly such that the tax payable for that year plus the provisional tax for the following year is less than the provisional tax already paid, the Inland Revenue Department will refund the overpaid provisional tax.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    Using the above figure as an example, provisional tax paid for 2024\/25 is $12,123, but the tax payable for 2024\/25 ($4,941) plus provisional tax for 2025\/26 ($6,441) totals $11,382. Therefore, $741 can be refunded.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
