A. Perhaps the most important tax rule change for many retirees will be the increase in the standard deduction. For older taxpayers who don’t carry a mortgage and have limited deductions, that standard deduction is often more valuable than itemized deductions. That will be the case for even more people, as the tax law roughly doubled the size of the standard deduction.
At the same time, the additional standard deduction for the elderly will still be available. In 2017, the tax rules allowed individual tax filers over age 65 to claim an additional standard deduction of $1,550, and married couples over the age of 65 could increase their standard deduction by $2,500. The new rules would increase these higher standard deductions for people over age 65 to $1,600 per individual and $2,600 per couple.
On the other hand, the new tax code eliminated personal exemptions. Still, many retirees may come out ahead due to the higher standard deduction, rate cuts, and other changes (see below).
