Do I have to file at home while living in Zimbabwe?
Residence decides it, and residence is a question of facts rather than of where your post arrives. The one exception is US citizenship, which carries the filing obligation with the person wherever they go. So the first thing we establish is which system still claims you.
Is there a treaty between my country and Zimbabwe?
Possibly, and the version in force for your year is the one that matters — protocols and multilateral-instrument positions change what a treaty does without changing its name. We check it against the authority rather than a summary. Where no treaty applies, domestic relief takes over.
I own property in Zimbabwe. Where is the rent taxed?
Rent from immovable property is almost always taxable where the property is situated, frequently by withholding on the gross amount, with your home country taxing the same income and giving credit. A net-basis election, where one exists, is usually the difference between tax on profit and tax on turnover.
How do currency and remittance constraints affect reporting Zimbabwean income at home?
Currency and remittance constraints can affect both the exchange rate used to convert Zimbabwean income and the evidence available to support what was actually earned and received, so a home-country return reporting Zimbabwean-source income often needs more supporting documentation than a straightforward conversion would require.
Does holding legacy assets in Zimbabwe create an ongoing reporting obligation for a Zimbabwean-Canadian?
Yes — legacy assets held in Zimbabwe by a Canadian or American resident generally need to be considered under the home country's foreign asset and income disclosure rules, regardless of how difficult the assets are to value or convert given local currency conditions.
Why might a professional on a regional African assignment need Zimbabwe-specific advice rather than general expat guidance?
Because Zimbabwe's currency and remittance environment creates practical evidencing challenges that a general expat tax framework does not address, so a professional with Zimbabwean income or assets needs the specific local constraints factored into how their home-country return is prepared.
Where does the exclusion go on the return, and does it change my rate?
It is computed on Form 2555 and carried to the return as a negative adjustment to income, so the excluded amount is out of taxable income. It does not, however, pretend you never earned it: the tax on whatever income remains is calculated as though the excluded amount were still there, so the remaining income is taxed at the rates that apply above it. Deductions and credits attributable to excluded income are also disallowed. See the foreign earned income exclusion.
Does California allow the foreign earned income exclusion?
No. California does not conform to it, so foreign salary a resident excludes on the federal return is still in the California base — and California does not give a credit for foreign tax in the way it does for tax paid to other states. The result is the same income taxed federally at zero and by California in full. Whether it applies at all comes back to whether you are still a California resident, which is the question worth answering first. See state residency and domicile.
