Provisional tax and how to hold it over

Why Hong Kong collects tax in advance, how provisional tax is calculated and paid, and when you can apply to hold it over.

By DBMS GlobalLast reviewed: 18 October 2026

The answer first

Hong Kong collects provisional tax in advance for the current year, normally based on the profits (or income) assessed for the previous year. It is then credited against the final tax when the following year's assessment is made. For a profitable new company, the first assessment can be a surprise: it often includes the final tax for the first period and provisional tax for the next.

Provisional tax is usually paid in two instalments, roughly 75% and 25%. You can apply to hold it over on specified grounds, such as profits expected to fall below 90% of the previous year, within strict time limits.

At a glance

Based on
Usually the previous year's assessable profits
Instalments
About 75%, then 25% about three months later
Credited
Against the final tax for the year it relates to
Holdover deadline
28 days before the due date, or 14 days after the notice, whichever is later

How it works

StepWhat happens
AssessmentThe notice of assessment shows final tax for the past year and provisional tax for the current year
First instalmentUsually about 75% of provisional tax, combined with any final tax due
Second instalmentUsually the remaining 25%, about three months later
Next yearProvisional tax paid is credited against the final tax for that year
Key takeawaySet aside tax as profits are earned. In the first assessment, a company can face final tax and provisional tax together, often almost double what it expected.

Holding over provisional tax

Ground (examples)In brief
Lower profitsAssessable profits for the year are expected to be less than 90% of the previous year's
Ceased businessThe business has ceased or will cease during the year
LossesLosses are expected that reduce the year's profits
Other specified groundsAs set out by the Inland Revenue Department
DeadlineApply in writing not later than 28 days before the due date for payment, or 14 days after the date of the notice, whichever is later. Late applications are only accepted in limited circumstances. Supporting evidence, such as management accounts, is required.

Practical points

  • Base holdover applications on reliable figures; if the year turns out better than estimated, the difference becomes payable.
  • Tax reserve certificates can be used to save for tax payments.
  • Instalment arrangements may be possible in cases of genuine hardship, by application.
  • Late payment attracts surcharges and recovery action.
