My standard deduction should be 12000?

The increase in Standard Deductions is not effective until the 2018 tax year, not for the 2017 tax year.

Standard deductions for 2017 

• Single - $6,350 add $1,550 if age 65 or older
• Married Filing Separately - $6,350 add $1,250 if age 65 or older
• Married Filing Jointly - $12,700 add $1,250 for each spouse age 65 or older
• Head of Household - $9,350 add $1,550 if age 65 or older

how will that 15,200 MFJ both over 65 change in 2018?

For 2018 - Married Filing Jointly - $24,000 add $1,300 for each spouse age 65 or older

thanks that will more than cover loss of exemptions
