Provisional Profits Tax in Hong Kong: How It Works, and How to Hold It Over

By Di Ma, Project Manager 28 OCT 2026 · 4 MIN READ

A company's first profits tax bill often comes as a shock. It isn't only the tax on the year just finished. It also includes provisional tax for the year you're in now, worked out on the assumption that this year's profit will be the same as last year's. For a company in its first profitable year, the bill can be close to double what it expected.

What provisional tax is

Every person chargeable to profits tax is liable to pay provisional profits tax (section 63G of the Inland Revenue Ordinance). It's charged on the assessable profits of the preceding year, after any losses brought forward (section 63H), at the rates for that year (see profits tax rates). When this year's final assessment comes, the provisional tax you paid is credited against it: if you paid too much, the excess is set off or refunded; if too little, you pay the difference.

It arrives on the same notice of assessment as the final tax for the previous year, and is usually paid in two instalments: about 75% with the final tax, and the remaining 25% about three months later. The dates are on your notice.

A worked example

Example: a corporation with assessable profits of HK$1,000,000 for 2025/26, its first year of profit (two-tiered rates)
ItemAmountHow it's worked out
Final tax 2025/26HK$79,5001,000,000 × 8.25% = 82,500, less the 2025/26 one-off reduction of HK$3,000
Provisional tax 2026/27HK$82,500the same HK$1,000,000 at 8.25%; the one-off reduction doesn't apply to provisional tax
First paymentHK$141,375the final tax HK$79,500 + 75% of the provisional tax (HK$61,875)
Second payment, about three months laterHK$20,625the remaining 25% of the provisional tax

The first payment is nearly double the tax on the year's profit. If 2026/27 profits are similar, the provisional tax will roughly cover it, and from then on each year's bill is about one year's tax again. The surprise is a one-off, in the first profitable year, but it needs cash. Put both payments in your 13-week cash flow forecast as soon as the profit is known, not when the notice arrives.

Holding it over when profits fall

If this year is going worse than last, you can apply to the Commissioner to hold over (defer, in effect reduce) all or part of the provisional tax (section 63J). The grounds include:

The deadline

The application must be in writing and reach the IRD by 28 days before the payment's due date, or 14 days after the date of the notice, whichever is later (section 63J(1)). The notice of assessment states the date. It's usually still possible to apply for the second instalment if your figures change after the first has been paid.

The 90% test is about this year's profit, which is only known if the books are current. A company whose books are written up once a year usually can't show it in time, and pays the provisional tax anyway.

What to send

The Commissioner decides and tells you in writing. If the application is refused, or isn't made in time, the tax is due on the dates on the notice.

If you pay late

Tax not paid by its due date is in default. The Commissioner may add a surcharge of up to 5%, and a further surcharge of up to 10% on any amount still unpaid six months later (section 71). If you expect a cash problem, talk to your adviser before the due date, not after.

Frequently asked questions

What is provisional profits tax in Hong Kong?

An advance payment of profits tax for the current year of assessment, charged on the previous year's assessable profits (Inland Revenue Ordinance, sections 63G and 63H). It is credited against the final tax for the year when that is assessed.

Why is my first profits tax bill so high?

Because it usually includes both the final tax for the year just finished and provisional tax for the current year, worked out on the same profits. In the first profitable year that can nearly double the payment.

When is provisional tax paid?

Usually in two instalments shown on the notice of assessment: about 75% together with the final tax, and the remaining 25% about three months later. The exact dates are on your notice.

Can I reduce my provisional tax?

You can apply to hold over all or part of it under section 63J, for example if this year's assessable profits are, or are likely to be, less than 90% of last year's, if a loss brought forward was omitted, if the business is ceasing, or if you have objected to last year's assessment.

What is the deadline for a holdover application?

It must be lodged 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 (section 63J(1)).

What happens if I pay profits tax late?

The Commissioner may add a surcharge of up to 5% of the amount in default, and a further surcharge of up to 10% on any amount still unpaid six months later (section 71).

Know this year's profit before the IRD asks

With books kept current, you know whether this year's profit is falling in time to apply for a holdover, and the tax payments are already in your cash forecast.
