If you have moved to another country, there would be very little they could do as far as collecting any money you owe at this time. However, if the time ever comes that you would return to the country where the tax money is owed, you would probably face immediate levies on any wages or assets that you would acquire. If you think that is a possibility, you might want to try and work out a payment plan with them at this time, that way if you did move back you would already be locked in to some type of payment plan and not have to worry about levies being bade against your wages or assets.
