If you're not a US citizen, you won't have to pay income at all due to tax residency rules. only the US is brazen enough to charge non-resident citizens income tax
Don't forget Hungary, Myanmar, and Eritrea, too!
Anyway, the Hungary part surprised me since I'm a Hungarian citizen living abroad and have never been bothered about tax. The Wikipedia table says residents of countries with tax treaties are exempt, and that should be pretty much all of them? The PDF link from Wikipedia is broken, which is normal for how the Hungarian government operates.
"Put simply, all MPG does is tell you approximately how far your vehicle will travel based upon a single UK gallon, which equates to approximately 4.55 litres of fuel"
This particular thing, I'm aware of because there is perennial confusion over comparing mpg given that Imperial gallons are larger than American ones. If people just used L/100km....
Chauvinists go to ridiculous lengths to magnify small differences.
My point is more about how in the UK you might give a measure in one system, but then increasing the measure you might convert into a different system entirely. e.g. If you ask an Englishman how far apart you should stand for social distancing, he might say 2 meters. But if you ask him how far it is from London to Brighton, he might say it is 50 miles.
I didn't go looking for an example; it's one that I've run into a lot over the years, because people spontaneously ask why, over and over, American cars get much worse MPG than elsewhere. Not realizing the gallons are smaller.
For an Australia, you pay income tax if you're a resident for taxation purposes. For an Australian Citizen to answer that they're not a resident for taxation purposes is complicated and depends in part on the type of Visa you have.
Last I looked, for me, as an Australian citizen, to not have to pay tax would mean getting a permanent Visa in another country and being resident in that country. They specifically excluded time-limited visas, even if you can get them renewed automatically.
It means travelling around the world, even for years at a time, I still need to account for my income and lodge tax returns in Australia. The one upside is getting credit for income taxes paid in another country.
I believe a similar situation also applies to Canadian citizens, as a few former Canadian colleagues in Australia had to go through a whole process of getting their Australian taxation recognised in Canada.
Do you have any links to information regarding Australian citizens being taxed abroad? I know for HECS, etc you're still meant to lodge and pay those amounts, but didn't realise it might be a fair bit worse than that!
It's made more difficult because tax years don't align, so it needs to be worked out that way too. Oh, and because Switzerland probably put their tax records in Swiss-Fench/Swiss-German all your documents would need to be formally translated.
I'd start by checking put the ATO site they had a bunch of tests for your residency there.
Even if the time-limit is years at a time?
