Taxes can be tricky, especially if you own assets and earn an income in two places. What you pay in taxes when you're working abroad will depend on your nationality and where you reside. Notify the tax authorities where you're living now to let them know you'll be moving. You may be liable for fewer taxes or even be exempt.
Some countries have eliminated dual social security taxation. Under these bilateral social security agreements (SSA), for example, non-resident Indians (NRIs) are exempt from paying twice in 18 countries, including Australia, Canada, Japan, France and Denmark.
If you're working in another country or region for only part of a year, you may also be eligible for a tax refund when you return home, depending on the country.
Are you moving from a country with a residential system, like Canada, or a citizen-based system, like the US? With a few exceptions, citizens under the latter system must file taxes in their home country or region, no matter where they are in the world. If you're still earning money in your home country or region, such as through rental income or from the sale of property, you may still be liable for income or capital gains tax.
