i'm a canadian citizen, have always lived in canada, and have not filed a tax return in 30 years. I also have not been in anyone's 'employment' during that time. In addition the last income I did generate from any method is now ten years gone by (2006). but from 2004 to 2006 I did operate a small unregistered storefront service based business. so my question is now that myself and my parents/siblings are getting old enough to see the possibility of our inevitable passing it's been suggested I start filing returns again in order to have a record of filing before that happens (if for example my parents predecease me I will likely inherit 2-3 million dollars) does anybody have any relevant thoughts and/or suggestions as to whether this is necessary or not?
Some Additional Information
what i'm hoping to have confirmed is that any/all money earned between the time of my last filing (around 1986) and the last moment in time that I actually generated a (limited) income (Aug 2004 - Aug 2006) is far enough in the past that if I file a return for this year (and all years going forward) I won't be subject to any unnecessary scrutiny. I honestly have not needed generate an income in any capacity for what will soon be 10 years gone by (family money keeps my head well above water) and will not ever need to do so again in my lifetime. I'm just trying to decide now how far in front of things i'd like to be before the somewhat eventual day that I inherit that moderate amount of cash mentioned earlier. That date could be anywhere from 5-15-25 years from now, depending on how healthy we all remains.
