Online Tax Clearance - Permanent Departure

Is it possible to do tax clearance from abroad, having permanently departed HK?

I was a foreigner employed in HK until Dec 2025, and was looking for another job when I received an offer overseas late January. As I didn't plan to leave HK at the time of leaving my job in Dec 2025, my employer didn't provide an IR56G.

I had to leave HK in Feb and now I am looking to settle my taxes. I received IRF56G a couple of days after departure from HK and emailed IRD asking how to settle my tax obligations. They didn't respond yet. Though today, I see that they issued me a tax return to be filed for 2025/26 which has to be filed as paper-return, and by March 27. After rental deductions, my tax comes out about $1000 which is under the $1500 limit so it is eligible to be waived-off.

Can anyone please suggest the most painless way to do my tax clearance while physically not being in HK?

Thanks!
