Last year my standard deduction when filing jointly and over 65 was15100. is this the corect amount

For 2017 the standard deduction amounts are:
Single 6,350 + 1,550 for 65 and over
HOH 9,350 + 1,550 for 65 and over
Joint 12,700 + 1,250 for each 65 and over
Married filing Separate 6,350 + 1,550 for 65 and over

So for Joint with both spouses 65+ would be 12,700+1,250+1,250 = 15,200

Or do you want 2016?

For 2016 the standard deduction amounts are:
Single 6,300 + 1,550 for 65 and over
HOH 9,300 + 1,550 for 65 and over
Joint 12,600 + 1,250 for each 65 and over
Married filing Separate 6,300 + 1,250 for 65 and over

So it would be 15,100 for 2016
