Why is tax withheld on my gross rent and not my profit?
Because the default mechanism is collection at source from the payer, and the payer knows what the rent was, not what your costs were. Your agent or tenant is required to withhold from each payment and remit it, and the amount is calculated on the rent itself with nothing taken off. That is administratively simple and systematically too much, since it ignores every expense of owning the property. The route to being taxed on your actual profit is the elective return that the regime provides for non-resident owners, which is a separate step you have to take.
Can I deduct mortgage interest on my rental property abroad?
Only by electing to be taxed on the net income. While you are on the default basis the withholding is calculated on the gross rent, so interest, management fees, insurance, repairs and the rest count for nothing at all — not because they are disallowed, but because that basis never looks at them. Making the election changes the question from what the rent was to what the property earned, and expenses then come in on ordinary principles. Landlords who are geared are usually the ones for whom the difference between the two bases is largest.
What happens if I miss the deadline for the elective rental return?
The elective return has its own deadline, set by the regime that allows the election, and it is not the same date as ordinary filing. Missing it can leave the withholding on gross rent as the final tax for that year, with no route back to a net computation however large your expenses were. That is why the date matters more here than in most filings: the consequence of lateness is not a penalty on a figure but the loss of the basis itself. The deadline runs per year, so one missed year does not forfeit the next.
I have owned a rental abroad for years and never filed — what now?
Start by establishing what the position actually is, because two separate things may have gone wrong. Your agent may have withheld and remitted correctly, in which case the tax is largely paid and what is missing is the returns that would have reduced it. Or nothing was withheld at all, in which case there is unremitted tax as well as unfiled returns, and exposure can sit with the agent too. The years then have to be rebuilt from rent statements and expense records, and most administrations have a disclosure route worth approaching before they approach you.
Do I need a clearance certificate before selling my property?
In systems that operate one, the purchaser is required to withhold from the sale proceeds unless you obtain the certificate, and that withholding is calculated on the price rather than on your gain. On a long-held property bought for a fraction of its current value, that can exceed the tax actually due several times over. The certificate exists to align what is withheld with what is owed, and it is applied for around the transaction rather than after it. Without it, the money is recoverable only by filing, which takes far longer than the sale did.
Is my agent or me responsible for remitting the withholding?
Both, in different ways. The person paying the rent to a non-resident owner is generally the one obliged to withhold and remit, so an agent who collects your rent usually carries that duty and can be pursued for the tax if they fail in it. Reporting the income and making any election remains yours. Because the two obligations sit with different people, landlords discover a problem late: the agent believed the owner was handling it, the owner assumed the agent was withholding, and neither the remittances nor the returns were made.
What is Form 1042-S and what do I do with it?
The statement a US payer issues to a non-resident showing US-source income paid and tax withheld — the non-resident counterpart to a 1099. Use it two ways. In your own country it evidences the US tax paid for credit purposes. And where the rate withheld was higher than your treaty entitlement, or the income was not taxable at all, the way back to the money is a US non-resident return claiming the refund. Check the income and exemption codes before assuming the rate was right. See Form 1042-S.
Do green card holders living abroad have to file US taxes?
Yes. A lawful permanent resident is a US tax resident, taxed on worldwide income, and that status does not end simply because you moved away — it ends when it is formally abandoned or administratively terminated. Two traps follow. Filing as a non-resident on a treaty claim can put the immigration status itself at risk. And ending the status after holding it long-term can bring you inside the expatriation regime. See giving up a green card.
