Another tax break for seniors is the school tax exemption in some Georgia counties where people over 62 or 65 don't pay school taxes that would be included in property taxes.
Here's a link that covers counties in the Atlanta area:
That makes me want to convert all of mine and my wife's 401K money to Roth IRA's before I move to Georgia if I do move there in retirement. Since my wife and I will retire in different years, she before me, I plan to convert a huge chunk of her 401k each year to her Roth IRA -- as much as I can each year w/o going into a higher federal tax bracket. Then later when I retire do the same with my 401K.
But that means the first few years I'm retired I'll have a large taxable income for myself -- well past $65K. Hmmmm...of course I plan to retire in my late '50's anyway so I guess it won't matter. By the time my wife and I are 65 the only taxable income we'll have will be two pensions (which are taxable in Georgia, but neither over $65K) and each of us having SS (which is not taxable in Georgia). I should be done with Roth conversions even before we turn 62 (the lower Georgia income reduction for seniors).
