Understanding Provisional Tax and IRD Payment Schedules
How provisional tax works in Hong Kong, when you need to pay it, and what happens if you don’t. Covers payment deadlines and what to expect during assessment.
What Provisional Tax Actually Is
Provisional tax isn’t something new you owe. It’s the IRD’s way of asking you to pay your tax in advance, based on what they think you’ll earn this year. Instead of waiting until your assessment is done, you’re making installment payments throughout the year.
Here’s the thing: if you’re self-employed or freelancing, the IRD doesn’t know your income upfront. They can’t deduct it from your salary like they do for employees. So they estimate your tax liability and ask you to pay it in chunks. You’ll either get a refund or owe more when your actual assessment comes through.
Most freelancers get their first provisional tax demand in the March before their income year ends. It’s based on your previous year’s assessable income. If you’re new to freelancing or your income changes dramatically, you can request an adjustment.
The Payment Schedule — What You Need to Know
The IRD splits your provisional tax into two payments. For the 2025-26 tax year, you’ll pay roughly half your estimated liability twice. The first installment is due around April 1st. The second is due around October 1st. These aren’t random dates — they’re built into the system.
If you don’t pay on time, there’s a penalty. The IRD adds surcharge interest — usually around 5% if you’re a few days late, up to 10% if you’re significantly overdue. That’s on top of regular interest. It adds up quickly. We’re not talking huge amounts for a small freelance business, but it’s money you don’t want to throw away.
You can pay by several methods: internet banking, check, or at the post office. Most people use their bank’s electronic system since it’s instant and there’s a record.
Key Payment Dates to Remember
- First installment: Usually April 1st
- Second installment: Usually October 1st
- Both payments combined cover your estimated annual tax
- Adjustment deadline: Can request change if income differs significantly
What Happens When Your Assessment Comes
After the tax year ends (March 31st for most people), the IRD processes your actual assessment. They look at your real income, your expenses, and your allowances. If you’ve overpaid through provisional tax, you’ll get a refund. If you’ve underpaid, you’ll owe the difference.
The assessment usually arrives 4-6 months after the year ends. You’ve got 1 month to object if you think something’s wrong. Most freelancers don’t object unless there’s a genuine error, but you do have that option.
One thing that surprises people: if you owe more at assessment time, the IRD will contact you. They’re not looking to catch you out. They want the money, and they’ll give you time to pay if it’s a reasonable amount. But it’s always better to have accurate records so there aren’t surprises.
Keeping Track — What You Actually Need
You don’t need fancy accounting software to handle this. A spreadsheet works. Track your income month by month. Keep receipts for business expenses — and be realistic about what counts. A meal with a client? Maybe. Your personal lunch? No.
Most importantly, put money aside when you get paid. Don’t spend your entire fee. A simple approach: set aside 15-20% of each payment. That covers your provisional tax, your actual tax liability, and gives you a buffer. When your assessment comes, you’ll either have enough set aside or you’ll get a refund.
The IRD doesn’t make this complicated on purpose. They just need to know your income and your genuine business expenses. Keep it organized from the start, and provisional tax becomes routine instead of stressful.
The Bottom Line
Provisional tax isn’t complicated, but it does require attention. You’ll get a demand notice, you’ll make two payments a year, and you’ll get an assessment after the year ends. The IRD’s system isn’t designed to trap you — it’s just how they collect tax from self-employed people.
The best approach is straightforward: keep good records, set aside money each month, pay on time, and don’t panic when the assessment arrives. Most freelancers either get a refund or owe a small amount that they’ve already prepared for. It’s manageable when you’re organized from the start.
