For 2018, the standard deduction amounts will increase to $12,000 for individuals, $18,000 for heads of household, and $24,000 for married couples filing jointly and surviving spouse,s and the additional standard deduction amount for the aged or the blind is $1,300. The additional standard deduction amount increases to $1,600 for unmarried taxpayers.

Single or Married Filing SeparatelyStarting with tax year 2018 returns, the standard deduction will nearly double to $12,000 for single filers, $18,000 for head of household, and $24,000 for joint returns. Add another $1,300 for each taxpayer on the return who is over 65 or blind (plus another $300 if that taxpayer is also unmarried and not a surviving spouse).
The $4,050 personal exemption will be eliminated starting in tax year 2018. Even so, the number of taxpayers who itemize (currently around 30%) is expected to decrease as a result of the higher standard deduction.
