Do I have to file at home while living in Hong Kong?
It depends on residence, not on address — except for US citizens and green-card holders, for whom the answer is yes regardless of where they live. We settle the residence question first, because every other answer follows from it.
Is there a treaty between my country and Hong Kong?
Treaty networks change with each protocol and each multilateral-instrument position, so we confirm the treaty in force for your specific year with the issuing authority rather than relying on a published summary. Where there is none, unilateral relief and domestic law do the work instead.
I own property in Hong Kong. Where is the rent taxed?
In Hong Kong, because that is where the property sits. The complication is the base: gross-rent withholding takes no account of mortgage interest, tax or repairs, so a leveraged property can face tax on turnover. An election onto net profit, where it exists, is what fixes that — and it has its own timing.
I work from Hong Kong for an employer abroad — who taxes my salary?
Two systems can reach for the same pay for different reasons. A source-based system asks where the services were performed, which points at Hong Kong if that is where you sat while doing the work, regardless of where the employer or the payroll is. Your home country may still treat you as resident and tax the same salary worldwide. The resolution is usually relief for tax paid on the other side rather than one country standing down, and it depends on evidence: a day record, the contract, and payslips showing what was actually deducted and where.
Does my employer create a taxable presence because I work from here?
It is a real risk and it is the employer's question rather than yours, though you will be asked about it. What matters is the nature of what you do from Hong Kong, not merely that you are there. Work that is purely internal is analysed differently from work involving negotiating or concluding business with customers, and from anything that looks like a place of business kept at the company's disposal. Employers usually want the arrangement documented before it begins. We set out what the position rests on and what records the company needs to keep to support it.
Can I stay on my home payroll while living in Hong Kong?
Mechanically, yes, and it happens constantly. The difficulty is that payroll keeps deducting on the old basis while the work has moved, so tax is collected in one place and may be due in another. That is corrected through filings rather than automatically, and the correction is only as good as the day record behind it. Tell the payroll team the date the arrangement changed, ask what basis they are applying and get the answer in writing. Left unaddressed for a full year, this becomes two filings to reconcile instead of one to prepare.
I invoice overseas clients from Hong Kong — where is that income sourced?
Source follows the activity that produced the profit, not the address on the invoice or the bank that receives the payment. If you personally do the work while sitting in Hong Kong, that is a strong pointer, but the analysis looks at the whole operation: where contracts are negotiated, where the work is carried out, where the people and the decisions are. Clients based elsewhere do not by themselves move the source. Keep engagement letters, a record of where you were when the work was performed, and correspondence showing where it was agreed.
Do work trips out of Hong Kong change where my salary is taxed?
They can, and they are the part people fail to record. Where taxation follows the place the services were performed, days worked in a third country belong to that country's analysis rather than to Hong Kong's, and enough of them can create an obligation there too. Casual travel is different from a pattern of working days. What settles it is a contemporaneous record: dates, locations and what you were doing, kept as you go. Boarding passes and calendar entries reconstructed at the end of the year are the weakest version of this evidence.
My home country still withholds from my pay — what do I do?
Deal with it on two fronts. Correct the deduction going forward by telling the payer what has changed and providing whatever documentation lets a different basis apply, and recover any excess for the period already deducted through the filing that assesses your actual liability. Do not simply stop reporting the income because you think the deduction was wrong. Keep every payslip and remittance advice, because the credit or repayment you eventually claim has to be evidenced with what was paid, to whom, and in which period it fell.
What is a foreign tax credit?
A credit against your home-country tax for income tax you already paid to another country on the same income, so the same amount is not taxed twice at full rates. It is capped: you cannot credit more than your home country would have charged on that income, which is why a higher foreign rate leaves an unused balance rather than a refund. In the US it is claimed on Form 1116, in Canada on the T2209 and T2036, in India on Form 67. See Form 1116.
Does hiring one remote employee in another country create a tax presence?
It can, on two separate fronts, and the second applies even when the first does not. A permanent establishment may arise if the employee has a fixed place of business there or concludes contracts for you. Independently of that, employing someone locally generally brings payroll registration, wage withholding and social security contributions in their country from the first payroll — obligations that do not wait for a permanent establishment finding. Contractor paperwork does not by itself avoid either. See remote work and tax exposure.
