1 Human cells cultured in the lab have been observed to stop dividing when telomerase is inactivated, because the length of telomeres is not maintained after cell division.  The cells then enter a state of inactivity called senescence. However, once telomerase is reactivated, the cells are able to continue dividing.
In 2015, a taxpayer can give up to $14,000 per person per year without being taxed on the gift. For example, this year you could give Friend A $14,000, Friend B $14,000, and your sister $14,000 and not be taxed on your gifts.
By doing that, she could give even more without tax consequences. How the lifetime exclusion works. If you stay within the $14,000 annual exclusion, giving monetary gifts can be pretty simple. It's when you give more than $14,000 to any one person during the course of a year that things get a bit more complicated. You may have heard of the lifetime exclusion. This is the amount you can give above and beyond the $14,000 annual limit during the course of your life without incurring gift taxes. For 2015 that amount is a whopping $5,430,000 and will go up to $5,450,000 in 2016. With such a high limit, you'd be right to think that most people won't need to be concerned.
