Tax prep support
Estimated tax payment support
Support for Hong Kong's provisional Profits Tax instalments rather than a US-style estimated payment. The IRD issues a provisional assessment each year, payable 75 per cent with the prior year's final tax and the remaining 25 per cent roughly three months later, and we build both dates into your cash flow forecast so neither one catches you short.

A different mechanism to the same problem
Hong Kong has no quarterly estimated tax regime. Instead, the IRD issues a provisional Profits Tax assessment for the current year alongside your final assessment for the year just ended, and both become payable on a fixed instalment schedule.
The 75/25 split
Provisional Profits Tax is payable in two instalments: 75 per cent falls due with the final tax for the prior year, and the remaining 25 per cent follows roughly three months later. Missing either date brings a statutory surcharge, so we set reminders against both instalments as soon as the assessment notice arrives, not when the due date is close.
Holding back cash without guessing
Because the provisional figure is based on last year's profits, a fast-growing or a slowing business can end up over-paying or under-paying against the year actually being assessed. We compare the provisional demand to your current management accounts each quarter and flag when an application to reduce the provisional charge is worth raising with your CPA, rather than leaving the cash sitting idle or the shortfall building unnoticed.
Where this fits with the audit
The provisional demand itself does not need an auditor's involvement, it is a straightforward IRD notice. Where the figures on it look out of step with your actual trading, we raise that with your practising Hong Kong CPA, since any formal application to revise the assessment runs through them.
What we track for you
Each provisional demand lands with its own reference number and two due dates. We log both against your bookkeeping calendar the day the notice arrives, note the amount against your management accounts, and flag it in your monthly reporting pack so the instalment is never the first line you read about it.
Delivery
Every month's work is reviewed by a senior principal before it reaches you, and your file stays in your own Xero, QuickBooks Online or Zoho Books account.
Questions
Frequently asked questions: Estimated tax payment support
Does Hong Kong have quarterly estimated tax like the US?
No. The IRD issues one provisional Profits Tax assessment a year, payable in two instalments: 75 per cent with the prior year's final tax, and 25 per cent about three months later.
What happens if I miss a provisional tax instalment?
A statutory surcharge applies. We track both instalment dates from the moment the assessment notice arrives so the deadline is never a surprise.
Can the provisional tax amount be reduced?
Yes, through an application your practising Hong Kong CPA can raise with the IRD when your actual profits are running well below the provisional figure. We flag when that comparison suggests it is worth pursuing.
Do you calculate the provisional assessment yourselves?
The IRD calculates and issues the provisional assessment based on your prior year's profits. We reconcile it against your current numbers and manage the payment schedule.
Where does the provisional tax figure actually come from?
The IRD calculates it, usually based on your prior year's assessable profits, and issues the demand directly; our role is to check it against your current-year figures and flag if it looks out of step with them.
How do you calculate the estimate?
We project the year from actual results to date and check the number against a safe-harbor based on last year's liability, whichever protects you better.
What if income changes a lot during the year?
We revisit the projection through the year rather than setting it once at the start.
Who reviews the work before it reaches us?
Every deliverable under estimated tax payment support is reviewed by a senior principal before it reaches you. You keep access to the underlying file at every stage, so nothing about the work happens somewhere you cannot see it.
What is included in estimated tax payment support?
Estimated tax payment support covers quarterly income projection built from current-year books and estimated payment calculation for each due date. The exact scope is agreed and set out in writing before work starts, so you know precisely what is and is not covered before the first deliverable arrives.
