Personal Exemptions 
– For 2018, all personal exemption amounts for taxpayers, spouses and their dependents have been reduced to $0. In prior years, the total personal exemption amount reduced the taxpayer’s taxable income. There will be no reduction in taxable income due to personal exemptions on 2018 tax returns.

For 2018 the standard deduction amount will be $12,000 for Single and Married Filing Separately; $18,000 for Head of Household and $24,000 for Married Filing Joint and Qualifying Widow(er). The additional standard deduction amount for taxpayers that are age 65 or older and/or blind is $1,600 for Single and Head of Household and $1,300 for Married Filing Joint, Married Filing Separate and Qualifying Widow(er). The amount will not change for a dependent filing their own return. The standard deduction and remains $1,050 or $350 plus the dependent’s earned income, not to exceed the standard deduction amount for their filing status.

Special rules still exist for 2016 federally declared disasters and certain 2017 disasters (Hurricane Harvey or Tropical Storm Harvey, Hurricane Irma, Hurricane Maria and the California Wildfires).
  • All Miscellaneous Deductions that were subject to the 2% of the taxpayer’s adjusted gross income have been eliminated. This includes unreimbursed employee expenses, tax preparation fees, etc.
